Treatment of stellate ganglion block in diseases: Its role and application prospect.

The stellate ganglion (SG), as a type of sympathetic ganglion, consists of the sixth and seventh cervical vertebrae and the first thoracic sympathetic ganglia. SG block (SGB) is a minimally invasive injection that aims to inject low-concentration local anesthetics to induce a broad sympathetic blocking effect near the SG. There have been no changes and progress in the clinical application of SGB since the 1830s due to several potential risks, including hematoma from blood vessel injury, hoarseness from recurrent laryngeal nerve injury, and cardiopulmonary arrest.

A deep learning model based on contrast-enhanced computed tomography for differential diagnosis of gallbladder carcinoma.

Background: Gallbladder carcinoma (GBC) is highly malignant, and its early diagnosis remains difficult. This study aimed to develop a deep learning model based on contrast-enhanced computed tomography (CT) images to assist radiologists in identifying GBC.

Methods: We retrospectively enrolled 278 patients with gallbladder lesions (> 10 mm) who underwent contrast-enhanced CT and cholecystectomy and divided them into the training (n = 194) and validation (n = 84) datasets.

[Assay of 18 amino acids in Chuanmingshen violaceum roots by pre-column derivative HPLC].

The roots of Chuanmingshen violaceum is a commonly used Chinese herb and food, which contains rich amino acids. However, the kinds and amounts of amino acids are variety in this herb among the geographical location and ecological environment. Therefore, this study firstly developed a new pre-column derived HPLC method to quantify the levels of 18 amino acids in Ch.

Acupuncture protects the interstitial cells of Cajal by regulating miR-222 in a rat model of post-operative ileus.

Background: Recovery of the interstitial cells of Cajal (ICCs) during post-operative ileus (POI) is important for the restoration of gastrointestinal (GI) motility. Acupuncture can protect ICCs, but the underlying mechanisms remain unclear. In this study, we investigated whether miR-222, c-kit and endothelial nitric oxide synthase (eNOS) are involved in the putative effects of acupuncture on ICC recovery.

[Effect of Acupuncture on Expression of Receptor Tyrosine Kinase c-kit in Interstitial Cells of Cajal, Carbon Monoxide and Heme Oxygenase in Colon Tissue After Colonic Anastomosis in Rats].

Objective: To observe the effect of acupuncture on expression of receptor tyrosine kinase (RTK) c-kit in interstitial cells of Cajal (ICCs), carbon monoxide (CO) and heme oxygenase (HO) in colon tissue after colonic anastomosis, so as to explore the mechanism of acupuncture in improving gastrointestinal motility.

Methods: SD rats were randomly devided into control group, model group and acupuncture group. The model was established using colonic anastomosis.

Two new isoflavone 7-O-α-4″-anhydro-4″,5″-didehydroglucuronides from Streptomyces sp. LZ35ΔgdmAI.

Two isoflavone 7-O-α-4″-anhydro-4″,5″-didehydroglucuronides, namely daidzein 7-O-α-4″-anhydro-4″,5″-didehydroglucuronide (1) and genistein 7-O-α-4″-anhydro-4″,5″-didehydroglucuronide (2), were isolated and identified from the mutant strain of Streptomyces sp. LZ35ΔgdmAI. Their structures were elucidated by the analysis of their high resolution mass spectrometry (HR-MS) and 1D, 2D Nuclear magnetic Resonance (NMR) spectroscopic data.

Identification and catalytic characterization of a nonribosomal peptide synthetase-like (NRPS-like) enzyme involved in the biosynthesis of echosides from Streptomyces sp. LZ35.

Echosides, isolated from Streptomyces sp. LZ35, represent a class of para-terphenyl natural products that display DNA topoisomerase I and IIα inhibitory activities. By analyzing the genome draft of strain LZ35, the ech gene cluster was identified to be responsible for the biosynthesis of echosides, which was further confirmed by gene disruption and HPLC analysis.

Cuevaenes C-E: Three new triene carboxylic derivatives from Streptomyces sp. LZ35ΔgdmAI.

Two pairs of geometrical isomers - cuevaenes A (1) and C (3) as well as cuevaenes D (4) and E (5) - and cuevaene B (2) were isolated from gdmAI-disrupted Streptomyces sp. LZ35. The constitution of cuevaene C (3) was found to be identical to cuevaene A (1) by means of NMR spectroscopy and high resolution mass spectrometry.

[Efficacy controlled observation on acupuncture and western medicine for gastrointestinal dysmotility in liver cirrhosis].

Objective: To observe the therapeutic effect of acupuncture on gastrointestinal dysmotility in liver cirrhosis.

Methods: Forty cases of gastrointestinal dysmotility in liver cirrhosis were randomized into an acupuncture group and a motilium group, 20 cases in each one. In the acupuncture group, on the basis of the conventional treatment, electroacupuncture was applied at Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3) for 30 min, once a day.

Effect of arctiin on glomerular filtration barrier damage in STZ-induced diabetic nephropathy rats.

Diabetic nephropathy (DN) is the major life-threatening complication of diabetes. Abnormal permeability of glomerular basement membrane plays an important role in DN pathogenesis. This study was performed to assess the effect of arctiin, the lignan constituent from Arctium lappa L.

[Effect of acupuncture on gastrointestinal stem cell factor/kit system after colocolic anastomosis in rats].

Objective: To observe the effect of acupuncture on colonic stem cell factor (SCF)-receptor tyrosine kinase (Kit, a transmembrane protein c-kit) system in colocolic anastomosis rats so as to explore its underlying mechanism in regulating intestinal motility after enteroenterostomy.

Methods: Thirty SD rats were randomized into control, model (colocolic anastomosis) and acupuncture groups (n = 10/group). Acupuncture was applied to bilateral "Zusanli" (ST 36), "Sanyinjiao" (SP 6) and "Taichong" (LR 3), once a day for 3 days.

[Observation on the therapeutic effect of acupuncture treatment of autism children].

Objective: To observe the therapeutic effect of acupuncture ("Jin's Sanzhen") treatment for autism patients with different severity.

Methods: A total of 202 autism children were divided into treatment group (n=118) and control group (n=84) according to their parents' will. Autism children in the treatment group were treated with "Jin's Sanzhen" therapy [for example, Niesanzhen: the point 2 cun superior to the ear tip, and those at the same level 1 cun apart on the left and right sides; Naosanzhen: Naohu (GV 17), bilateral Naokong (GB 19), etc.
