200 units of eligible blood from donors with negative HBsAg reaction had been tested for hepatitis B virus markers (HBVM), using ELISA and dot-blot hybridization. The results of testing showed that 120 of the 200 units of blood had negative HBVM reaction, and the rest 80 units of blood had positive HBVM reaction. Among these 80 units of blood, 62 units had negative hepatitis B virus replication markers (HBVRM) and the rest 18 units had positive HBVRM. The rate, of post-transfusion HBV infection in the patients received HBVM (+) blood was 25.4%, significantly higher than the rate of post-transfusion HBV infection (3.75%) in the patients received HBVM (-) blood (P

Depression is the most common mental disorder in epilepsy, which means that they maybe have some common pathogene-sis. This paper discussed the biological relation mechanism, such as neurotransmitter, neuropeptide and its receptor, glial cell, immune-medi-ators, nerve signal transduction pathway, synaptic plasticity and nerve regeneration.

AIM: To investigate the effect of Ganoderma lucidum spores powder on the expression of insulin-like growth factor-1 (IGF-1), nuclear factor-?B (NF-?B) and apoptosis of nerve cells in rats with epilepsy established by pentetrazole. METHODS: The sub-eclampsia dosage of pentetrazole (PTZ) was used to make epilepsy model. Ganoderma lucidum spores powder group was given from stomach. The enduring time and latent period were recorded. The immune reactivity of IGF-1, NF-?B/P65 and apoptosis of nerve cells were measured with immunohistochemical staining and TUNEL method. RESULTS: In high power sight (?400), there were much more apoptosis cells in hippocampus and brain cortex of model group (18.80?2.13, 16.87?2.00) than those in control group (0.97?0.52, 0.58?0.25). The expressions of IGF-1, NF-?B in model group were higher than those in control group. Compared with model group, the latent period of Ganoderma lucidum spores powder group at the 17th, 21th, 25th days were longer (P

Objective:To explore the clinical effect of the V-Y plasty of musculocutaneous flap in repairing the excessive width of inner canthus deformity.Methods:Retrospective analysis was performed between July 2018 and June 2021 in patients treated with this method. V-Y design along the inner corner of the eye before operation. The key points of operation are the elevated under the orbicularis oculi muscle. The skin orbicularis oculi muscle flaps are formed on both sides of the incision. After the V-Y of the outside myocutaneous flap is advanced and formed at the new medial canthus point, the V-Y of the orbicularis oculi muscle and the skin are sutured in layers. The degree of reduction of the inner canthus width, epicanthal fold shape, incision scarring, and patient satisfaction was followed up. All patients were measured at the preoperative and postoperative review to record data of the intercanthal distance, and used paired t-test for statistical analysis. P<0.05 was statistically significant. Results:83 patients, including 81 female patients and 2 males, with an average age of 28 years (19 to 56 years) were followed up from 3 months to 2 years, with an average of 1 year. The overexposure of the tear caruncle was significantly reduced, the asymmetry of the bilateral inner corners has been improved, the shape of the epicanthal folds reverted to its natural appearance and the old scars became inconspicuous; patient satisfaction evaluation: very satisfied 34.94% (29/83), satisfied 54.22% (45/83), relatively dissatisfied 6.02% (5/83), dissatisfied 4.82% (4/83). Among the 4 cases of dissatisfaction, 2 cases were due to insufficient correction and were re-operated to obtain satisfactory result, 1 case was improved by reoperating due to excessive correction which led to the reduction of inner canthal distance, 1 case regrets surgery the next day after surgery and cannot accept the appearance and strongly requires removal and restoration. The distance between intercanthal distance of the patients was 28.8 mm to 38.0 mm, average (33.58±3.34) mm before the operation, and 32.2 mm to 41.5 mm, average (37.47±2.90) mm after the operation, an average increase of 3.89 mm ( t=-15.78, P<0.001) after the operation. Conclusions:The V-Y plasty of musculocutaneous flap is suitable for the repair of excessive width of inner canthus deformity after epicanthoplasty. The design idea is simple, the postoperative effect is reliable, and the postoperative satisfaction rate of patients is high.

Objective To observe the influence of Bugan Jianyao Fang (Liver-tonifying Lumbarinvigorating Decoction) on expressions of intervertebral disc matrix metalloproteinase-3 (MMP-3) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in rats with lumbar disc degeneration.Methods SD rats (n =75) were randomly divided into sham-operation group,model group,Yaobitong (Waist Impediment-Freeing Capsules) group,doxycycline (DOX) group and Bugan Jianyao Fang group (each n =15).Mter establishing successfully the model of lumbar disc degeneration in rats,all groups were,respectively,given orally Yaobitong,DOX and Bugan Jianyao Fang.The expressions of intervertebral disc MMP-3 and TIMP-1 were detected in all group after and 20 d and 4 d after intervention.Results After intervention for 20 d and 40 d,the expressions of intervertebral disc MMP-3 and TIMP-1 decreased in Yaobitong group,DOX group and Bugan Jianyao Fang group compared with model group (P ＜0.05).The difference in expressions of intervertebral disc MMP-3 and TIMP-1 had statistical significance in Yaobitong group,DOX group and Bugan Jianyao Fang group after intervention compared with those in the same groups before intervention (P ＜ 0.05).The comparison among Bugan Jianyao Fang group,Yaobitong group and DOX group showed that the difference had no statistical significance (P ＞ 0.05) at all time points.Conclusion Bugan Jianyao Fang can reduce the expressions of intervertebral disc MMP-3 and TIMP-1 in rats with lumbar disc degeneration,which may be one of mechanisms of Bugan Jianyao Fang preventing and curing lumbar disc degeneration.

Objective: To introduce the SVF-gel as a filling, and the application of SVF-gel for the treatment of horizontal neck wrinkles. Methods: This investigation presented a retrospective study of 30 patients (age ranged from 25 to 56 years, with mean 36 years) in Guangzhou Eye-Nose-Fat Cosmetic Plastic Clinic from December 2017 to June 2019. We used the SVF-gel injection for horizontal neck wrinkles for the patients. The effectiveness was observed 1 to 6 months later. Results: No serious complications occurred in all patients. Postoperative evaluation of horizontal neck wrinkles showed that the swelling time lasted for 1-3 days, and the satisfactory rate of the doctors and patients after one month was 83.33% and 86.67%, and that after 6 months was 86.67 % and 83.33%, respectively. Conclusions SVF-gel is an effective treatment for horizontal neck wrinkles.

Objective:To investigate the relationship between parathyroid hormone（PTH） level and permanent hypoparathyroidism（PHPP） on the first day after radical papillary thyroidectomy, and its predictive value. Methods:A total of 80 patients with papillary thyroid cancer who underwent total thyroid resection and central lymph node dissection were collected and analyzed from January 2021 to January 2022. According to whether PHPP occurred after surgery, the patients were divided into hypoparathyroidism group and normal parathyroid function group, and univariate and binary logistics regression were used to analyze the correlation between PTH and serum calcium levels and PHPP on the first day after surgery in two groups. The dynamic changes of PTH at different time points after operation were analyzed. The area under the receiver operating characteristic was used to evaluate the predictive power of PTH on the development of PHPP after surgery. Results:Among the 80 patients with papillary thyroid cancer, 10 cases developed PHPP, with an incidence rate of 12.5%. Binary logistics regression analysis showed that PTH on the first postoperative day（OR=14.534, 95%CI: 2.377-88.858, P=0.004） was an independent predictive risk factor for postoperative PHPP. Taking PTH=8.75 ng/L on the first postoperative day as the cut-off value, the AUC of the area under the curve was 0.874（95%CI: 0.790-0.958, P<0.001）, the sensitivity was 71.4%, the specificity was 100%, and the Yoden index was 0.714. Conclusion:PTH level on the first day after total thyroid papillary carcinoma surgery is closely related to PHPP, and is an independent predictor of PHPP.
