Surgical operation is still the main means of thyroid carcinoma,especially the differentiated thyroid carcinoma. Postoperative endocrine therapy is considered as an important adjuvant therapy. Giving the corresponding endocrine therapy after the surgery,not only prevent the hypothyroidism,but also reduce the recurrence rate and mortality in postoperative patients with thyroid carcinoma.

Cell polarity is a common feature of many different types of cells,and it is essential to the normal differentiation and function of cells. Partitioning defective 6( PAR6)gene encodes PAR6 protein, which is crucial to asymmetric cell division and polarized growth. PAR6 protein as a member of the PAR6 polarity complex,affects the synthetic of centrosome and protein recruitment to the centrosome. The abnormal number of centrosomal and the loss of cell polarity may eventually lead to the occurrence of tumor.

Objective To evaluate the clinical effect of laparoscopy in the modified nerve painesparing radical hysterectomy (NPSRH) of early stage cervical cancer.Methods From January 2014 to December 2015 in our hospital,38 patients with early cervical caucer were enrolled and randomly divided into NPSRH group and laparoscopic radical hysterectomy (LRH) group in the study.The surgery general situations of two groups were compared,and postoperative intestinal and bladder function of these patientswere also assessed.Results All of 38 patients were successfully completed the operation,without significant intraoperative or postoperative complications.There were no significant differences in the bleeding volume,pelvic lymph dissection number,cut length of main ligament and sacral ligament,cut length of anterior vaginal wall,and posterior vaginal wall between two groups (P ＞ 0.05).The mean operation time in NPSRH group was longer than in LRH group,but the duration of postoperative hospital stay was shorter than the latter (P ＜ 0.01).Compared to control group,the catheter retention time,residual urine volume,maximal micturition volume,and Qmax in the NPSRH group recovered better,and with lower rate of nocturia mnd dysuria (P ＜ 0.05).The exhaust time and anal defecation time in the NPSRH group were significantly shorter than the LRH group,and lower rate of constipation additionally (P ＜ 0.05).Conclusions The laparoscopy in the modified nerve paine-sparing radical hysterectomy is a safe and effective measurement for the treatment of early-stage cervical cancer patients.It can significantly reduce the duration of postoperative hospital stay,promote the functional recovery of bladder and rectum,and improve the patients'postoperative quality of life.

BACKGROUND:It is unclear whether hydrogen-rich water can be used to protect skeletal muscle injury induced by eccentric exercise, as wel as the relative mechanism. OBJECTIVE:To observe the effect of hydrogen-rich water on the mitochondrial oxidative stress and inflammation in rat skeletal muscle after eccentric exercise, and to investigate the relative signaling pathway of hydrogen-rich water. METHODS:Forty Sprague Dawley rats were randomly divided into four groups: control group, eccentric exercise group, eccentric exercise+saline group, and eccentric exercise+hydrogen-rich water group. Rats in three eccentric exercise groups were exercised on a motor-driven rodent treadmil at a speed of 16-18 m/min and a slope of-16° for 90 minutes per day. Rats in the eccentric exercise+hydrogen-rich water group were subjected to intraperitoneal injection of hydrogen-rich water (10 mL/kg) immediately after exercise; and rats in the eccentric exercise+saline group were administrated with normal saline after exercise. Al the interventions lasted for 5 days. RESULTS AND CONCLUSION:Hydrogen-rich water intervention after eccentric exercise could markedly enhance the mitochondrial Sirtuin-3 expression, improve the mitochondrial membrane potential and activity of manganese superoxide dismutase, down-regulate the mitochondrial reactive oxygen species generation and mitochondrial DNA oxidative damage, thus inhibiting inflammatory cytokines expression, such as NLRP3 and interleukin-1β. The results indicated that hydrogen-rich saline could directly scavenge reactive oxygen species. In addition, hydrogen-rich water could improve mitochondrial energy metabolism and antioxidant capacity through up-regulation of Sirtuin-3, which in turn inhibits eccentric exercise-induced mitochondrial oxidative stress and secondary inflammation in the skeletal muscle.

Objective: To evaluate the therapeutic effect of gamma knife on patients with intracranial cavernous angioma (CA). Methods: The medical records of 122 patients (134 lesions) who underwent radiosurgery were reviewed retrospectively. Results: hT e average follow-up period was 43 months. No patient died. One patient underwent CA resection. In patients with epilepsy, 83% patients showed alleviation of seizures. About 44% of the lesions shrank in size after treatment with gamma knife radiosurgery (59/134). Seven cases had hemorrhage again after radiosurgery, and the overall annual hemorrhage rate was 1.6%. Edema was found in 11.5% patients (14/122) and all patients showed improvement atf er treatment. Conclusion: Gamma knife is a safe treatment for CA, which could obviously improve the symptoms of epilepsy. Gamma knife radiosurgery is the if rst option for the treatment of cavernous sinus angiomas.

Objective To study activation effect of a natural compound baicalein on cystic fibrosis transmembrane conductance regulator(CFTR) chloride channel.Methods A cell-based fluorescence assay was used to determine CFTR-mediate iodide influx rate/dt(mmol?L-1?s-1)] activated by baicalein(the concentrations were 0.18,0.55,1.65,5,15,44,133 and 400 ?mol?L-1).Results The Ka of flavonoid baicalein stimulating CFTR was about 16 ?mol?L-1.The half of maximal activity was reached in ten minutes and the activation disappeared in 20 min after baicalein was washed out.The activation of baicalein was not affected obviously under different concentrations of Forsklin(0,20,50 and 100 nmol?L-1)and the activation could be totally inhibited by CFTRinh-172.Conclusion Baicalein can stimulate CFTR-mediated iodide influx in a dose-dependent way and its activity manifests a rapid and reversible characteristic.It might work in both elevating CFTR protein phosphorylation and direct binding way.

Objective To assess the association of three polymorphisms in Megsin (rs1055901,rs1055902 and rs2689399) and susceptibility of IgA nephropathy in Asian population.Methods We conducted a comprehensive search of electronic CNKI,VIP,WangFang Data,CBM,Pubmed,Web of Science and Google Scholar database on the association between Megsin rs1055901,rs1055902 and rs2689399 polymorphism and susceptibility of IgA nephrology in Asian population (last search update on 2 May 2016).Stata 12.0 software was used to calculate the odds ratio (OR) and 95 ％ CI (confidence interval),as well as sensitivity and publication bias analyses.Results Six publications encompassing mine case-control studies were finally included,including 2 179 cases and 1 769 controls.Finally,no significant association between Megsin rs1055901 and rs1055902 polymorphism and IgA nephrology in Asian population was identified,while a significantly decreased risk of IgA nephrology for rs2689399 polymorphism,was identified in Asian population (G and C:OR=0.754,95％CI 0.592-0.961,P=0.022;GG and CC:OR=0.506,95％CI 0.287-0.892,P=0.019;GG and GC+CC:OR=0.551,95％CI 0.316-0.961,P=0.036).Conclusion Rs2689399 G allele and GG genotype of Megsin may be the protective factors for IgA nephropathy in Asian population.

Objective:To investigate the expression of human epidermal growth factor receptor 4 (HER4) and metastasis-related protein (MMP-9) in human esophageal carcinoma tissues, and their relationship with clinicopathological features of the disease. Methods:Immunohistochemical Envision technique was applied to detect the expressions of HER4 and MMP-9 in 45 specimens of esophageal carcinoma tissues, paracancerous tissues and normal tissues. Statistical method was used to analyze the association of the positivity of HER4 with clinical pathological index and MMP-9 expression.Results:The positive rates of HER4 expression were 73.3%, 33.3%, and 2.2% in 45 specimens of esophageal carcinoma tissues, paracancerous tissues, and normal tissues, respectively. The expression of HER4 was correlated with TNM stage and lymph node metastasis (P<0.01), but not correlated with histological grade (P>0.05). The expression of MMP-9 correlated with T stage, invasion depth, TNM stage, and lymph node metastasis (P<0.05). Conclusion:The expression of HER4 is apparently different in esophageal carcinoma tissues, paracancerous tissues, and normal tissues. Its positive expression in esophageal carcinoma tissues is correlated with TNM stage and lymph node metastasis. The expression of MMP-9 in esophageal carcinoma tissues is correlated with the T stage, TNM staging, and lymph node metastasis. The positive expression of HER4 in esophageal carcinoma tissues is associated with the expressions of MMP-9.

Objective To explore the relationship of plasma level of B-type natriuretic peptide (BNP) with cardiovascular risk,the severity of coronary heart disease(CHD),and the short-term prognosis in patients with type 2 diabetes. Methods 154 patients with type 2 diabetes,of them 95 cases complicated with CHD and 65 with hyper-tension were selected in this study. The CHD patients were diveded into 3 groups: AMI(n=32), UAP(n=33) and SAP(n=30). The relationship of the plasma BNP levels with cardiovascular risks, with each coronary heart disea-ses,were observed. The patients were followed up for 6 months to study the predicting role of BNP on the death in pa-tients accompanied with CHD. Results The plasma BNP level was (397.34±217.79) ng/L, which was correlated with age, CRP, hypertension and CHD (r=0.631,0.672, 0.762,0.857, P<0.05 for each);the plasma BNP levels increased with age(r=0.896,P<0.01):(57.6±12.3) ng/L in patients <50 years old,(146.2±53.4)ng/L in patients 50≤and < 59 years old, (388.4±67.5) ng/in patients 60≤and < 69 years old, and (423.8±132.6) ng/L in patients≥70 years old (P<0.01 or P<0.05). The plasma BNP levels, was higher in patients with hyper-tension than that in patients without hypertension [(314.7±125.3) ng/L vs (136.8±98.7) ng/L, P<0.01];Higher in patients with CHD than that in patients without CHD [(425.03±200.80)ng/L vs (37.64±21.57) ng/L,P<0.01)]. The short-term prognosis of patients with CHD was correlated with the levels of BNP, and BNP levels≥485 ng/L may be an independent predicting factor for cardiac death within one month. Conclusions Plas-ma levels of BNP were associated with some cardiovascular risks,which may be one of biomarkers for cardiovascular risks in patient complicated with CHD.
