Objective To investigate anti-ulcerative drug use in patients undergoing arthroscopic operation against stress ulcer. Methosds A total of 297 patients undergoing arthroscopic operation during Jan. to Aug. 2013 in our hospital were recruited and retrospectively analyzed with Excellspreadsheet. Results Among 297 patients in the study, ninety-four patients (31.6%) used AUD before operation, most (94.9%) administered by intravenous, and drug utilization index was 1.35. Ninety-eight point nine patients used proton pump inhibitors (PPIs) in which Lansoprazole was prescribed most. Conclusion This study highlights the overuse of PPIs in patients undergoing arthroscopic operation.

OBJECTIVE:To investigate sodium intake via drug used by hypertensive inpatients during hospitalization. METH-ODS:290 inpatients with hypertension were collected from vasculocardiology department of our hospital between Jan. and Oct. 2013. The types of sodium-containing drugs and sodium-intake during hospitalization were analyzed statistically. RESULTS:275 pa-tients with hypertension were prescribed 38 sodium-containing drugs(94.8%);82.7% were administered by iv gtt with a average drug treatment course of 6.7 days(average hospitalization days of 6.8 days). Solvent containing sodium such as 0.9% Sodium chlo-ride injection and Creatine phosphate sodium for injection were the most sodium donors. 43.3% patients’sodium intake exceeded upper limit of 2 g/day recommended by WHO. CONCLUSIONS:Hypertensive inpatients are prescribed too much sodium-contain-ing drugs,and less intravenous solutions and less adjuvant medicines should be took to decrease sodium intake. Only when prospec-tive benefit are greater than risk,the patients can be prescribed sodium-containing drug prescription.At the same time,manufacturers should annotate the content of sodium in package inserts,which is convenient for physicians to choose drugs.

Objective To explore the effect and potential mechanism of suppressors of cytokine signaling 3 (SOCS3) knockout on cell viability and apoptosis of retinal ganglion cells (RGCs) after optic nerve injury.Methods The optic nerve transection was used to construct optic nerve injury model of rats,and RGCs were isolated after optic nerve injury.The experimental animals were divided into optic nerve transection injury (ONT) group and sham-operation (Sham) group.The expression of SOCS3 in RGCs was detected by Western blot and RT-PCR in each group.Subsequently,SOCS3 siRNA was transfected into RGCs of Sham group and ONT group,and the experimental were further subdivided into blank control group,negative control group and SOCS3 silence groups.Cell viability was measured by CCK8 and MTr methods.Apoptosis was detected by Hoechst 33342 staining and flow cytometry.Furthermore,the mTOR siRNA and SOCS3 siRNA were co-transfected into RGCs,and cell viability and apoptosis were detected.Results The expression of SOCS3 was dramatically increased at 3 days after injury in the ONT group when compared with Sham group (P =0.049),and it showed an increased tendency gradually along with the extension of injury time.Compared with the blank control in the ONT group,SOCS3 silence markedly promoted cell viability [(49.47 ± 7.35) ％ vs.(73.24 ± 8.70) ％],reduced cell growth inhibition [(27.25 ±0.75)％ vs.(10.96 ± 1.07)％] and apoptosis [(23.06 ± 1.43)％ vs.(10.65 ± 1.77)％].The result of Hoechst 33342 staining indicated that SOCS3 silence ameliorated the cell apoptosis induced by ONT.In addition,SOCS3 silence significantly improved pS6 expression at 2 weeks after injury,and mTOR and SOCS3 co-silence reduced cell viability,increased cell growth inhibition and apoptosis compared with SOCS3 silence group after injury.Conclusion SOCS3 silence promotes injury-induced cell viability of RGCs and suppresses injury-induced apoptosis of RGCs via up-regulating mTOR activity in the later period of injury.

Objective To explore the distributions of genotypes of HPV infection in CIN and cervical carcinoma. Methods Cervical exfoliated cells were collected from 365 patients with abnormal cervical histology , and subjected to genotyping assay. Results The most prevalent HPV types were 16, 18,52, 58 and 33. The prevalence ratio of HPV 33,52,58 was signi cantly lower in squamous cell carcinoma. Multiple infections decreased from CIN II/III to cervical cancer. Conclusion Besides HPV 16/18, the 52/58/33 subtypes are also important in the development of cervical cancer.

Objective:To explore the treatment effect of A-NK cells on the subcutaneously transplanted tumor of tongue squamous cell carcinoma in nude mice.Methods:Tca8113-Tb cells were subcutaneously transplanted into nude mice,14 tumor bearing mice were randomly assigned to 2 groups(n =7).The mice in control group were injected with normal saline,those in the experimental group were injected with A-NK cells.All animals were killed 33 days after tumor cell transplantation,The tumor volume and weight of the mice were measured and compared.Results:A-NK cells significantly inhibited tumor growth in nude mice in terms of the volume (P ＜0.05).After 15 -33 d of treatment the tumor weight(g)in the treated and control mice were 0.96 ±0.38 and 3.74 ±1.22 re-spectively(P ＜0.05).Conclusion:A-NK cells can inhibit the growth of Tca8113-Tb cell induced tumor in nude mice.

Aim To study the effect and molecular mechanism of pretreatment with COPP on hypoxia/reoxygenation injury of H9c2 myocytes.Methods H9c2 myocytes model of hypoxia/reoxygenation injury was established and H9c2 myocytes were given COPP pretreatment before hypoxia/reoxygenation.Treatment with Znpp and all-trans retinoic acid(ATRA)inhibited HO-1 and Nrf2-ARE respectively.The level of LDH and CK in cell supernatants were measured.HO-1mRNA expression was analyzed by RT-PCR.HO-1 and Nrf2 protein expressions were analyzed by Western blot.Results Compared with hypoxia/reoxygenation group,the level of LDH and CK in COPP pretreatment groups decreased significantly and the level of HO-1mRNA,HO-1 protein expression and Nrf2 protein expression in the nucleus significantly increased.Znpp abolished protective effect of COPP pretreatment.ATRA blocked the nuclear accumulation of Nrf2 and decreased HO-1 protein expression that COPP pretreatment induced.Conclusions COPP can induce HO-1 overexpression which has protective effect on hypoxia/reoxygenation injury of H9c2 myocytes.Its mechanism is related to Nrf2-ARE signaling pathway.

OX40 (CD134) is a costimulatory molecule on the surface of T cells. It binds to OX40L (CD252) that is expressed on the surface of antigen presenting cells (APC) and participates in the transmission of the second signal of T cell activation, indicating that it is of great importance to the proliferation, differentiation, survival and migration of T cells. In theory, blocking the OX40/OX40L costimulatory pathway can suppress immune response and induce immune tolerance. In this review, we reviewed the research progress in OX40/OX40L-induced transplantation tolerance.

Objective:To observe the effect of Tuina(Chinese therapeutic massage)combined with functional training in improving clinical symptoms and balance function in patients with meniscus injury. Methods:A total of 93 patients with grade Ⅰ-Ⅱ meniscus injury were randomly divided into a functional training group,a Tuina group,and a combination group,with 31 cases in each group.The Tuina group received Tuina manipulation.The functional training group underwent functional training under the supervision of physicians.The combination group received Tuina manipulation in addition to the functional training.The treatment course of all three groups was 8 weeks.The clinical symptoms were observed before the intervention and after 4 and 8 weeks of interventions,and the changes in knee injury and osteoarthritis outcome score(KOOS)and Y-balance test(YBT)were compared. Results:There was no statistically significant difference in the total response rate among the three groups after treatment(P>0.05).The total and subscale KOOS in the three groups were significantly higher than those before treatment after 4 and 8 weeks of interventions(P<0.05).There was a statistically significant difference in the total KOOS between the combination group and the functional training group after 4 and 8 weeks of interventions(P<0.05);there was a statistically significant difference in the score of daily living ability and sports and recreation function between the two groups after 8 weeks of interventions(P<0.05).The YBT balance coefficients of the affected and non-affected knees of the three groups were significantly improved after 4 and 8 weeks of interventions(P<0.05),and there was no statistically significant difference among the groups(P>0.05). Conclusion:Tuina,functional training,and their combination can improve clinical symptoms and balance function in patients with grade Ⅰ-Ⅱ meniscus injury.Tuina combined with functional training is significantly effective in improving daily living ability and sports and recreation function.

Data analysis poses a significant challenge to the large-scale proteomics studies. Based on the structured and controlled vocabularies-Gene Ontology (GO), and the GO annotation from related databases, a strategy composed of several programs and local databases is developed to identify the functional distribution and the significantly enriched functional categories of the proteomic expression profile. It would be helpful for understanding the overall functions of these identified proteins and supply the fundamental information for further bioinformatics exploration. This strategy has been successfully used in the Human Fetal Liver (HFL) proteomic research, which is available online at http://www.hupo.org.cn/GOfact/.

Objective To reveal the difference between the standards for genu varum and genu valgum in the medical standard directory PLA Air Force( PLAAF) for recruitment of flying cadets and those adopted in the United States Air Force ( USAF) , and suggest a method for the reform of our flying cadets recruitment.Methods The rejection rate and comprehe nsive assessment qualification rate of genu varum and genu valgum during physical examinations for recruitment of flying cadets between 2012 and 2015 were analyzed.The different standards for genu varum and genu valgum in PLAAF and USAF flying cadets recruitment were compared and subjected to an empirical study.Results During the final physical examination for selection of flying cadets between 2012 and 2015, only 18 candidates were eliminated because of genu varum and genu valgum, accounting 9.1% of the total eliminated candidates because of orthopadics diseases.Four candidates with genu varum and genu valgum passed the comprehensive assessment in 2014 and 31 in 2015, which accounted for 15%of the candidates with orthopaedics diseases approved by comprehensive assessment.The standards for genu varum and genu valgum in PLAAF were based on morphology while those in the USAF based on the function of knees.According to the USAF medical standard directory, 9 of the candidates rejected because of genu varum and genu valgum were qualified and 9 disqualified.Among the candidates with genu varum and genu valgum approved by comprehensive assessment, 32 were qualified and 3 disqualified.Conclusion The standards for genu varum and genu valgum in PLAAF medical standard directory are of lower accuracy.The standards of USAF should be referred to and the function of knees should be considered in selection of flying cadets.Femur-tibia angle should be measured to improve the morphological standards.
