Landform and lithospheric development contribute to the assembly of mountain floras in China.

Although it is well documented that mountains tend to exhibit high biodiversity, how geological processes affect the assemblage of montane floras is a matter of ongoing research. Here, we explore landform-specific differences among montane floras based on a dataset comprising 17,576 angiosperm species representing 140 Chinese mountain floras, which we define as the collection of all angiosperm species growing on a specific mountain. Our results show that igneous bedrock (granitic and karst-granitic landforms) is correlated with higher species richness and phylogenetic overdispersion, while the opposite is true for sedimentary bedrock (karst, Danxia, and desert landforms), which is correlated with phylogenetic clustering.

The importance of temperature monitoring in predicting wound healing.

Upon wound formation, the wound temperature rises in the first 3-4 days until reaching its peak. It then falls at about one week after wound formation. In the second week after wound formation, the wound temperature decreases steadily to the baseline indicating a good wound condition and progression towards healing.

Methods: From April 2020 to September 2021, 25 women with vaginal laxity underwent vaginal tightening, and 22 women were included in this retrospective observational study.

 (Commelinaceae), a new species from Guangdong, China.

(Commelinaceae), a remarkable new species from Mount Danxia, Guangdong Province, China, is described and illustrated. This species is similar to in inflorescences and flowers but readily distinguishable in its nearly erect stems, larger flowers, and different petal colouration.

 (Lamiaceae), a new species from Jiangxi, China.

(Lamiaceae), a new species from Jiangxi Province, China, is described and illustrated. The new species is morphologically similar to , but can be easily distinguished from the latter by its cordate leaf base ( cuneate, decurrent), stem and calyx tube with glandular hairs ( short pubescent), and glabrous anthers ( ciliate anthers). A phylogenetic analysis, based on ITS regions, suggests that represents a separate branch in and is closely related to Clade II.

 (Rubiaceae), a new species from Guangdong, China.

, a new Rubiaceae species from E'huangzhang Nature Reserve, Guangdong Province, China, is here described and illustrated. A morphological comparison between the new species and its putative relatives, , and , is presented. The new species is mostly similar to , but they can be distinguished from each other since presents solitary flower (vs.

Research on the variants of FGFR1 and CEP290 genes in idiopathic hypogonadotropin hypogonadism.

Idiopathic hypogonadotropic hypogonadism (IHH) is a rare endocrine disease characterized by gonadal dysplasia. According to whether the sense of smell is affected, this disorder is classified into Kallmann syndrome (KS) and normosmic isolated hypogonadotropic hypogonadism (nIHH). In this study, we reported a case of nIHH patient and explored the pathogenic mechanism of FGFR1 in nIHH.

Case Report: Improved surgical treatment for breast capsular contracture by the punctiform-incision approach through the nipple.

Capsular contracture is one of the most common complications of breast implants, which often leads to secondary surgery. Patients with unconspicuous breast contracture do not need treatment, while for those with severe symptoms, a capsule revision surgery is of great necessity, including a total periprosthetic capsulectomy and replacement with a new implant. However, if the capsular contracture happens in the submuscular space, it will be very difficult to release it completely, and it may lead to more complications such as damage to surrounding tissue.

The compound losartan cream inhibits scar formation via TGF-β/Smad pathway.

The role of angiotensin receptor blocker in wound healing and cutaneous fibrosis has become a hotspot in recent years. We have developed a losartan cream that is comparable to triamcinolone ointment in inhibiting scarring. Considering the effects of chitosan and asiaticoside on wound healing and scarring, we added them to the losartan cream this time and improved the formula, expecting to get a better anti-scarring effect.

Effects of chitosan-collagen dressing on wound healing in vitro and in vivo assays.

The present study was designed to fabricate a new chitosan-collagen sponge (CCS) for potential wound dressing applications. CCS was fabricated by a 3.0% chitosan mixture with a 1.

The Roles of Inflammation in Keloid and Hypertrophic Scars.

The underlying mechanisms of wound healing are complex but inflammation is one of the determining factors. Besides its traditional role in combating against infection upon injury, the characteristics and magnitude of inflammation have dramatic impacts on the pathogenesis of scar. Keloids and hypertrophic scars are pathological scars that result from aberrant wound healing.

The efficacy of fractional CO laser in acne scar treatment: A meta-analysis.

Fractional CO laser is a good option for treating acne scars. However, the clinical efficacy of this treatment modality requires further evidence. To perform a meta-analysis to assess clinical improvements in acne scars with fractional CO laser and non-CO laser therapies.

New combinations and synonyms in (Styracaceae).

We demonstrate with morphological characters that the species W.W.Sm.

Flexible electrical stimulation device with Chitosan-Vaseline® dressing accelerates wound healing in diabetes.

The healing process of diabetic wounds is typically disordered and prolonged and requires both angiogenesis and epithelialization. Disruptions of the endogenous electric fields (EFs) may lead to disordered cell migration. Electrical stimulation (ES) that mimics endogenous EFs is a promising method in treating diabetic wounds; however, a microenvironment that facilitates cell migration and a convenient means that can be used to apply ES are also required.

Clinical value of bedside abdominal sonography performed by certified sonographer in emergency evaluation of blunt abdominal trauma.

Purpose: To investigate the accuracy and efficiency of bedside ultrasonography application performed by certified sonographer in emergency patients with blunt abdominal trauma.

Methods: The study was carried out from 2017 to 2019. Findings in operations or on computed tomography (CT) were used as references to evaluate the accuracy of bedside abdominal ultrasonography.

Angiotensin-converting enzyme inhibitor and angiotensin II type 1 receptor blocker: Potential agents to reduce post-surgical scar formation in humans.

Studies on the effectiveness and mechanisms of reducing scar formation by interfering with the renin-angiotensin-aldosterone-system (RAAS) have been demonstrated in animals, but not in humans due to the lack of clinical support. Our aim was to investigate whether angiotensin-converting enzyme inhibitor (ACEI) and angiotensin II type 1 receptor blocker (ARB) could inhibit scar formation in humans. Thus, an observational and hypothesis-generating study using a designed questionnaire was carried out.

CO Laser Punch-Assisted Minimally Invasive Surgery for Sebaceous Cysts.

Background And Objectives: Traditional surgical excision for a sebaceous cyst can completely eradicate the cyst, but the surgical processes are relatively complicated and may cause obvious scarring. Some patients are reluctant to choose this method because of the inconvenient procedures and the risk of conspicuous scarring, especially in esthetically important areas. We present a simple treatment method to prevent formation of a conspicuous scar.
