Objective To observe and analyze the clinical effect of laparoscopic assisted vaginal hysterectomy and vaginal hysterectomy for non prolapse of uterus.Methods From March 2015 to April 2016,126 cases of uterus benign lesions received surgical treatment in our hospital were selected and divided into observation group and control group.The observation group was given laparoscopic assisted vaginal hysterectomy resection,while the control group was given routine vaginal hysterectomy.The blood loss,operative time,hospitalization time and complications incidence were compared between two groups.Results The operation time and the amount of bleeding in the observation group were significantly higher than that in the control group,the difference was statistically significant (P ＜ 0.05).The length of stay in the observation group was significantly shorter than that in the control group,the difference was statistically significant (P ＜ 0.05).There was no significant difference in the incidence of surgical complications between the two groups (P ＞ 0.05).The quality of life of the two groups was compared with the total score,the observation group was higher (230.79 + 9.54),P ＜ 0.05,the difference was statistically significant.Concltsion Laparoscopic assisted vaginal hysterectomy and vaginal hysterectomy in the treatment of non prolapse uterus has a good clinical effect,should be chosen and applied based on the actual situation of patients.

Quantum dots( QDs) as a new type of nanostructured luminescent materials have been widely used in biology, materials science, and physical optics. QD-based biosensors can rapidly and accurately detect biological macromolecules or inorganic molecules both in vivo and in vitro. The surface of QDs, prior to their biological detection applications, needed to be modified to enhance their fluorescence properties and lower their biological toxicity. Currently, the surface modification technologies mainly include polymer modification, thiol compounds modification, mercapto propionic acid compounds modification and organic groups modification. Various biosensors can be developed by adopting different modification techniques, which have been adopted to locate and track a variety of biological molecules in vivo. Although a large number of literatures have reported the biological applications of QD-based biosensors, rare systematic reviews of surface modification technologies on QDs have been witnessed. In this paper, we reviewed the surface modification technologies of QDs in biosensors and their medical applications.

Objective To investigate the expression situation of thyroid cancer related gene-1 (TC-1),CyclinD1 andβ-catenin in the tissues of non-small cell lung cancer(NSCLC)and their relationship with the clinical pathologic characteristics,to analyze their relationship with the regulation of Wnt/β-catenin signal pathway to provide the basis for studying the role of TC-1 in NSCLC. Methods The expressions of TC-1,CyclinD1 and β-catenin in 48 patients with NSCLC were detected by immunohistochemical SP method and analyzed by combining the clinical pathological features.Results The expression levels of TC-1,CyclinD1 andβ-catenin in the NSCLC tissue were significantly higher than those in the normal lung tissue;in which,the expression of TC-1 in NSCLC tis-sue was associated with lymph node metastasis and TNM stages;the expression ofβ-catenin in NSCLC tissue was related with the pathological types and tissue differentiation degree.Conclusion The expressions of TC-1,CyclinD1 andβ-catenin show the up-regu-lating trend in NSCLC and may play an important role in the development of lung cancer;TC-1 may be involved in the regulation of Wnt/β-catenin signaling pathway,which provide the new research thought of the NSCLC targeted therapy.

Parathyroid hormone ( PTH) is an important hormone secreted by parathyroid cells , and regulates the metabolism of calcium and phosphorus in the body .In recent years , the toxic effect of PTH on myocardium has been re-ported.Calcium-sensing receptor (CaSR), a member of G protein-coupled receptor family, can feel the subtle change of extracellular calcium concentration and regulate intracellular calcium concentration through multifarious ways in order to control the secretion of PTH .The expression of CaSR is observed in parathyroid cells , renal tubular epithelial cells , myo-cardial cells, etc.Intracellular calcium, as a second messenger, participates in various cell functions , such as excitation-contraction coupling , fertilization and so on .The injury of myocardial cells is intimately linked with high concentrations of PTH and intracellular calcium , and high expression of CaSR .

To explore the relationship between HPRE mutations and noncytolytic anti-HBV infection, the objective eukaryotic expression vectors were constructed by molecular cloning and PCR-based site-directed mutagensis in vitro, and identification was performed using PCR and sequencing analysis. The results showed that eukaryotic expression vectors containing HPRE segment and mutating point were constructed successfully as confirmed by sequencing analysis. The activity of CAT gene obviously increased in the T to C mutation at nt 1504 of HPRE and no alteration in the C to T(G) at nt 1508. The mutation at nt 1508 of HPRE may escape the suppression role of IFN-?on HPRE. These results suggested that the mutation of HPRE might be affected the function of HPRE and influence the regulative function of IFN-? on HPRE, but not of 1FN-? nor of TNF-?.

Objective To explore diagnosis, treatment and prevention of remnant gallbladder from laparoscopic cholecystectomy (LC). Methods A retrospective analysis was performed for the clinical data of 12 patients treated in our hospital for remnant gallbladder caused by LC from December 1994 to December 2007. Results The occurrent rate of the remnant gallbladder in LC was 0.46%(12/2609). All the 12 patients with remnant gallbladder received surgical operations and 3 of them had remnant gallbladder with stones. Remnant gallbladders in the 12 cases were removed by surgical operations and were cured. Conclusion Ultrosonic or MRI examination is preferable and surgery is the effective treatment for this disease. For avoiding the occurrence of the remnant gallbladder in LC,it is essential to adhere to indications of LC before operation and standards of the surgical procedures.

OBJECTIVETo explore the role of traditional Chinese medicine (TCM) syndrome scores in effectiveness evaluation of clinical studies.

METHODSRandomized controlled trials (RCTs) of TCM published in five journals in 2013 were retrieved, including Journal of Traditional Chinese Medicine (JTCM), Chinese Journal of Integrated Traditional and Western Medicine (CJITWM), Chinese Journal of Integrative Medicine (CJIM), Evidence-Based Complementary and Alternative Medicine (ECAM), and American Journal of Chinese Medicine (AJCM). The details of TCM syndrome scores and other relevant factors reported in articles were extracted and analyzed. Descriptive statistics and Chi-square test were used to describe general features of inclusive studies, ratios of reports on CM syndrome scores in each journal, formulated evidence, adopted evaluation rules, important degrees. The difference in the application rate of CM syndrome scores were compared in various diseases, diseases with or without CM syndrome typing, places where clinical studies were implemented, and different journals.

RESULTSA total of 240 RCTs were included, involving 178 published in Chinese version and 62 in English version. CM syndrome scores were used for effectiveness evaluation in 27.1% (65/240) of RCTs, of which, the highest application percentage was 35.3% (18/51) in RCTs published in CJITWM, and the lowest was 0 (0/7) in RCTs published in AJCM. There were 17 methods for grading TCM syndrome scores, of which Guideline for Clinical Research of New Chinese Herbal Medicine was most commonly used. Detailed grading standards for CM syndrome scores were reported in 46 RCTs, and CM syndrome scores were taken as primary or secondary outcomes in 6 RCTs. When describing the percentages of RCTs adopting TCM syndrome score by diseases classification, the lowest was 9.5% (2/21) in mental and behavioral disorders, and the highest was 39.1% (9/23) in endocrine, nutritional, and metabolic diseases. RCTs with TCM syndrome differentiation had a higher percentage of adopting TCM syndrome score than those without TCM syndrome differentiation (P < 0.01). Statistical differences were also found among RCTs published in Chinese core journals (32.0%), domestic science citation index (SCI) journals (28.6%), and overseas SCI journals (4.9%) (χ2 = 12.4593, P < 0.01). For RCTs conducted by Chinese scholars, the percentage of using TCM syndrome score was 32.0% in three journals from China, while 7.1% in two foreign language journals, showing significant difference (χ2 =7.3615, P < 0.01); none of RCTs conducted by foreign scholars used TCM syndrome scores for effectiveness assessment.

CONCLUSIONSThere was a lack of agreeable and universal standards for TCM syndrome scores using in effectiveness evaluation. Therefore, it was not commonly used in domestic CM clinical studies. It was not so favorably agreed in overseas academic circles.
