[Analysis of lumbosacral sagittal balance parameter variation in minimally invasive transforaminal lumbar interbody fusion with real-time 3D navigation techniques].

Objective: To explore the dynamic changes of lumbosacral sagittal parameters after real-time three-dimensional navigation assisted minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and traditional open TLIF for treatment of lumbar degenerative disease.

Methods: The clinical data of 61 patients with lumbar degenerative disease underwent single-segment surgery from September 2017 to September 2019 were retrospectively analyzed. Among them, 31 cases underwent MIS-TLIF with 3D navigation techniques (MIS-TLIF group) and another 30 cases underwent conventional open TLIF (traditional open TLIF group).

[Low-dose testosterone undecanoate capsules combined with tadalafil for late-onset hypogonadism accompanied with ED].

Objective: To observe the clinical effect of low-dose testosterone undecanoate capsules combined with tadalafil on late-onset hypogonadism (LOH) accompanied with ED.

Methods: Ninety cases of LOH accompanied with ED who met the inclusion criteria were randomly divided into a control group and a combination therapy group, the former treated with tadalafil and the latter with low-dose testosterone undecanoate capsules combined with tadalafil. The LOH symptoms, IIEF-5 scores, sexual encounter profile (SEP) scores, prostate volumes, and the levels of total testosterone (TT), free testosterone (FT) and prostatic specific antigen (PSA) were recorded and compared between the two groups before and after treatment.

Root-derived auxin contributes to the phosphorus-deficiency-induced cluster-root formation in white lupin (Lupinus albus).

Formation of cluster roots is a typical morphological response to phosphorus (P) deficiency in white lupin (Lupinus albus), but its physiological and molecular mechanisms are still unclear. We investigated the role of auxin in the initiation of cluster roots by distinguishing the sources of auxin, measuring the longitudinal distribution patterns of free indole-3-acetic acid (IAA) along the root and the related gene expressions responsible for polar auxin transport (PAT) in different developmental stages of cluster roots. We found that removal of shoot apex or primary root apex and application of auxin-influx or -efflux transport inhibitors, 3-chloro-4-hydroxyphenylacetic acid, N-1-naphthylphthalamic acid and 2,3,5-triiodobenzoic acid, to the stem did not affect the number of cluster roots and the free-IAA concentration in the roots of P-deficient plants, but when these inhibitors were applied directly to the growth media, the cluster-root formation was greatly suppressed, suggesting the fundamental role of root-derived IAA in cluster-root formation.

Nitric oxide is the shared signalling molecule in phosphorus- and iron-deficiency-induced formation of cluster roots in white lupin (Lupinus albus).

Background And Aims: Formation of cluster roots is one of the most specific root adaptations to nutrient deficiency. In white lupin (Lupinus albus), cluster roots can be induced by phosphorus (P) or iron (Fe) deficiency. The aim of the present work was to investigate the potential shared signalling pathway in P- and Fe-deficiency-induced cluster root formation.

Transarterial chemoembolization compared with conservative treatment for advanced hepatocellular carcinoma with portal vein tumor thrombus: using a new classification.

We aimed to compare the survival benefit of transarterial chemoembolization (TACE) with conservative treatment for patients with advanced hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT), furthermore, to reveal which PVTT types benefit from TACE treatment. From August 2007 to January 2010, a prospective controlled study was performed on consecutive patients with advanced HCC and PVTT. Of a total of 150 patients, 115 were treated with TACE (lipiodol and anticancer agents ± gelatin sponge embolization), and 35 who refused to accept the procedure were treated with conservative treatment.

Iron deficiency-induced increase of root branching contributes to the enhanced root ferric chelate reductase activity.

In various plant species, Fe deficiency increases lateral root branching. However, whether this morphological alteration contributes to the Fe deficiency-induced physiological responses still remains to be demonstrated. In the present research, we demonstrated that the lateral root development of red clover (Trifolium pretense L.

[Repairing the defect of benign bone tumor with the coralline hydroxyapatite].

Objective: To observe the clinical effect of repairing bone defectin post-operation benign tumor with coralline hydroxyapatite(CHAP).

Methods: The natural coralline was treated into coralline hydroxyapatite by "hydrothermal exchanging" at specific condition. The CHAP was implanted into the lesion after bone tumor curettage to 25 patients.
