ABSTRACT

Objective:To investigate the efficacy of microsurgical decompression in carpal tunnel syndrome (CTS) caused by different etiologies.Methods:A retrospective analysis was performed. The clinical data of 54 patients with CTS, admitted to our hospital from January 2018 to December 2018, were chosen; 20 patients were with idiopathic CTS (20 laterals), 16 patients were with diabetic-related CTS (26 laterals), and 18 patients were with dialysis-related CTS (22 laterals). All patients were treated with median nerve microsurgical decompression. Before surgery and 2 weeks after surgery, Boston carpal tunnel questionnaire (BCTQ) was used to evaluate the symptom and function scores, and median nerve conduction velocity was detected.Results:Intraoperatively, there was definite nerve entrapment in all three groups, but the neuropathy scopes in the diabetic-related CTS group were more extensive than those in the idiopathic group and dialysis-related CTS group. The postoperative BCTQ symptom and functional scores in the three groups were significantly decreased as compared with the preoperative ones ( P<0.05); however, there were no significant differences among the three groups in the postoperative BCTQ symptom and functional scores ( P>0.05). The postoperative sensory nerve conduction velocity and motor nerve conduction velocity in the three groups were significantly improved as compared with the preoperative ones ( P<0.05). There were significant differences among the three groups in postoperative sensory nerve conduction velocity and motor nerve conduction velocity ( P<0.05); the sensory nerve conduction velocity and motor nerve conduction velocity in the diabetic-related CTS group were significantly decreased as compared with those in idiopathic CTS group, and the sensory nerve conduction velocity and motor nerve conduction velocity in dialysis-related CTS group were significantly increased as compared with those in the diabetic-related CTS group ( P<0.05). The main surgical complications in three groups included poor incision healing: the incidence was 5% (1/20) in the idiopathic group, 15.3% (4/26) in the diabetic-related CTS group, and 18.1% (4/22) in dialysis-related CTS group, without significant differences ( χ2=1.755, P=0.416). Conclusion:Microsurgical decompression can achieve satisfactory results in the treatment of dialysis-related CTS, diabetes-related CTS and idiopathic CTS.

ABSTRACT

Objective To investigate college students' awareness and cognition of 84 shared courses on the Internet and analyze the discrepancies between different ethnicity and majors in Xinjiang Medical University. Methods Purposive sampling was adopted with questionnaire of 1 448 students of 26 classes in Xinjiang Medical University. The survey aimed to investigate students' awareness and cognition of these In- ternet courses. Obtained data were statistically analyzed using SPSS 13.0, and the test level α=0.05. Result The hits of preventative medicine, Chinese medicine, clinical medicine and pharmacy were 19.0%, 33.3%, 35.7% and 11.9% respectively. Among the courses whose hits exceeded 50,000, clinical medicine accounted for 50%, preventive medicine for 21.4%, Chinese medicine and pharmacy for 14.3% respectively, there being no significant difference in overall hits (P>0.05). 90.1% of the surveyed students knew shared courses on the Internet, there being no difference between gender, ethnicity and profession (P>0.05). 89.8% had an accurate understanding of the concept of shared courses on the Internet, there being differences between gender and major ( χ2gender=11.013, P=0.026; χ2major=136.08, P=0.000) without significant differences in ethnicity ( χ2=11.378, P=0.497). 71.9% of the students used shared courses on the Internet as reference resources for the course study, 46.6% for the learning content, 35.5%for the understanding of other resources related to the course, 30.1% for lab-class and exercises, 10% for discussion on online course forum. The Han and Kazak students used the courses as a study, experiment and exercise tool, while the Uyghur and Kazak mainly used these for learning and discussion on the forum, there being differences in ethnicity ( χ2=26.889, P=0.001); the usage rate of the courses of preventive medicine students is higher, whereas pharmacy students relatively low, there being significant differences in major ( χ2=38.01, P=0.004). The Kazakh and Uygur students mainly used the courses to formulate learning plans, and the Han students to learn the current curriculum. 44.7% of preventive medicine students used the courses to improve their abilities, which was significantly higher than those of other majors. Only 18.4% and 1% of pharmacy students used the courses to formulate learning plans and to improve their abilities, which were both lower than those of other majors, showing ethnic and professional differences ( χ2ethnic=37.654, P=0.001; χ2major=73.68, P=0.000). Conclusion Students' awareness of shared courses on the Internet is high and their cognition is accurate. However, there are differences in the ways and purposes of the employment of the courses between different ethnicity and majors. The main reason may be related to major, the quality of the courses, as well as the lack of effec-tive supervision and evaluation system, suggesting that the management department in our university should strengthen the supervision and evaluation of the courses and give full play to the important role of shared courses on the Internet.

ABSTRACT

Objective To investigate the promotion effect of Danhong injection (DH) on brain-derived neurotrophic factor (BDNF) expression in Schwann cells (SCs) of SD rats.Methods In experiment of SCs apoptosis induced by advanced glycation end products (AGEs),SCs were divided into control group,AGEs treatment group and DH+AGEs treatment group; 48 h after each treatment,the SCs count was compared.In experiment of DH affecting mRNA and protein BDNF expressions in SCs,real time-PCR and Western blotting were used.In the experiment of DH combined with different inhibitors (Calphostin C,LY294002,H89,U0126,FR180204 and SB203580) affecting mRNA BDNF expression in SCs,real time-PCR was used.Results The number of SCs in AGEs treatment group was significantly decreased than that in the control group,but that in DH+AGEs treatment group was statistically increased than that in AGEs group (P<0.05).The mRNA and protein expressions of BDNF in the DH treatment group were significantly increased than those in the control group (P<0.05).As compared with DH group,DH+Calphostin C treatment group had significantly decreased BDNF mRNA expression (P<0.05); BDNF mRNA expression in the DH+U0126,DH+FR180204 and DH+SB203580 treatment groups was significantly decreased as compared with that in the DH treatment group (P<0.05).Conclusions DH could effectively inhibit SCs apoptosis induced by AGEs and significantly promote BDNF expression;protein kinase C (Calphostin C) and mehtyl ethyl ketone (U0126)/extracellular regulated protein kinases (FR180204EK)/p38 (SB203580) may be the important signaling transconduction pathways for BDNF expression.

ABSTRACT

We present a case of subarachnoid hemorrhage induced by chronic suppurative otitis media and discuss the possible mechanism here. Chronic suppurative otitis media is a common suppurative inflammation of middle ear, which can cause sorts of extracranial and intracranial complications in the situation of lower resistance or higher virulence. However, the condition of subarachnoid haemorrhage caused by chronic suppurative otitis media is quite rare. According to this case and previously published articles, we consider that meningitis may be the main reason of subarachnoid hemorrhage induced by chronic suppurative otitis media.

ABSTRACT

Objective To study methods and effect of granule bone grafting into the vertebral pedicle pyramid under endoscope for treatment of thoracolumbar fractures. Methods There were 26 cases (7 males and 19 females; age range of 32 79 years, average 51.2 years) with thoracolumbar fractures. The fractures included 8 cases (30.8%) of thoracolumbar compression burst fractures with no compression of the spinal cord by broken bone fragments and 18 (69.2%) compression fractures due to senile osteoporosis. Posterior to a preliminary reduction of the lumbar region on the operating table, all cases underwent vaginal vertebral pedicle reduction under endoscope and autogenous or hererogeneous granule bone graft in order to restore the height of the fractured vertebra pyramid. The patients kept in bed for two months postoperatively; meanwhile, the excise for the back muscle was performed. Results The mean follow up period was 3 18 months. Twenty one cases (80.8%) got excellent therapeutic result, four (15.4%) moderate and one (3.8%) poor. (1) The vertebral height recovered average 29%, with mean height loss of 5% through six month follow up. (2) The posterior convex cobb angle of the spine recovered for 10? 20? (mean 13.8?). (3) No lumbago or nerve compression symptoms were found in 21 cases. Conclusions Granule bone graft into vertebra pyramid under endoscope in the treatment of thoracolumbar fractures is a minimally invasive procedure that can enhance the bone capacity of the vertebra, alleviate pain, restore the height of the fractured vertebra pyramid and accelerate bone healing.
