Torque teno virus(TTV)is a nonenveloped virus containing a single-stranded,circular DNA genome of approximately 3.8kb.We completely synthesized the 3808 nucleotides of the TTV(SANBAN isolate)genome,which contains a hairpin structure and a GC-rich region.More than 100 overlapping oligonucleotides were chemically synthesized and assembled by polymerise chain assembly reaction(PCA),and the synthesis was completed with splicing by overlap extension(SOEing).This study establishes the methodological basis of the chemical synthesis of a viral genome for use as a live attenuated vaccine or gene therapy vector.

Objective:To prepare and evaluate the effectiveness of chitosan-carboxymethylcellulose membrane in preventing postoperative intestinal adhesion.Methods: Chitosan-carboxymethylcellulose membrane was prepared with 11 ratio of chitosan and carboxymethylcellulose.Glutaraldehyde and ammonium aluminium sulfate were used for cross-linkage,glycerin for enhancing plasticity;and then the product was dried.The membrane was observed with scanning electron microscopy(SEM) and its tensile strength and breaking elongation were measured.Forty-eight SD rats with ileum injury were randomly divided into A,B and C groups(n=16).During operation,the injury in group A was treated with chitosan-carboxymethylcellulose membrane,in group B with chitosan membrane,and in group C without treatment(control group).The adhesion was observed on the 14~(th) postoperative day.Results: The tensile strength of chitosan-carboxymethylcellulose membrane was 20 MPa and the breaking elongation was 65%.SEM showed that the morphology of the membrane had crossed fibroid structures and irregular pores. The severity of adhesion in group A and B was significantly lower than that in group C(P

Objective:To investigate the effect of carboxymethylchitosan on autocrine growth factor and morphology of fibroblasts cultured in vitro,so as to discuss the possible mechanism by which carboxymethylchitosan alleviates overhealing and prevents adhesion in wound healing.Methods: Fibroblasts were cultured in vitro.Fibroblasts of passage 4-6 were treated with different concentrations of carboxymethylchitosan(0.01,0.1,1.0 and 10 mg/ml) for 4 days or with 0.1 mg/ml carboxymethylchitosan for 1,2,3, 4,5,and 6 days.The levels of autocrine transforming growth factor-?_(1 )(TGF-?_(1)) and epidermal growth factor(EGF) of fibroblasts were determined by ELISA and radioimmunoassay.The fibroblastic morphology was detected by transmission electron microscopy(TEM) and microscope after fibroblasts were treated with different strategies.Results: Carboxymethylchitosan(≥0.1 mg/ml)inhibited autocrine TGF-?_(1) of fibroblast in a time-and concentration dependent manner(P0.05).Carboxymethylchitosan ((≥0.1 mg/ml))also inhibited the proliferation of fibroblasts and caused their ultrastructural changes.Conclusion: Carboxymethylchitosan (≥0.1 mg/ml)can inhibit fibroblasts proliferation and reduce tissue adhesion, possibly through altering fibroblast ultrastructure and selectively inhibiting secretion of TGF-?_(1).

Objective:To explore the perioperative safety management of patients with severe limb dysplasia, to select appropriate methods to monitor vital signs, and to prevent intraoperative acquired pressure sore, nosocomial infection and other related complications.Methods:A case of severe developmental disorder of extremities caused by acroscleroderma in November 2019 in Peking University Shenzhen Hospital needed to be amputated. By organizing multidisciplinary consultation to discuss the operation plan, repeatedly selecting appropriate tools, and multiple scenario simulation exercises, continuous transcutaneous oxygen saturation and noninvasive blood pressure monitoring could be realized for the patients with acromegaly deficiency of the extremities. Under the monitoring of color ultrasound, the arterial blocking pressure of the extremities was determined as the tourniquet pressure during the operation value, take appropriate measures to prevent intraoperative acquired pressure sore, nosocomial infection and other related complications.Results:With the cooperation of multidisciplinary team, amputation was successfully carried out for the patients. The position was comfortable during the operation, the operation process was smooth, the residual limbs healed well after the operation, and there was no intraoperative acquired pressure sore, nosocomial infection and other related complications.Conclusions:To establish a multidisciplinary cooperation mechanism, strengthen the construction of the operating room special group, and use evidence-based nursing methods and actual scenario simulation exercise can ensure the perioperative safety of patients with severe developmental disorder of extremities and similar patients with special body shape or very low weight.

BACKGROUND: Electrical muscle stimulation can certainly improve muscle protein synthesis and muscle mass growth, but there are also different research results. OBJECTIVE: To analyze the influence of electrical muscle stimulation as a strength training method on the muscle strength of exercisers through meta-analysis, providing advanced method and evidence-based basis for future strength training in sports field. METHODS: Databases such as PubMed, EBSCO host, Web of Science, CNKI, WanFang, and VIP were searched for randomized controlled trials regarding electrical muscle stimulation for improving the muscle strength of exercisers. The literatures were screened by PICOS principles. The subjects were athletes and healthy controls with exercise experience, and they were divided into electrical stimulation group and control group (without any intervention). According to Cochrane criteria we conduct meta-analysis, sensitivity analysis, subgroup analysis, and publication bias evaluation through Stata 15.1 and Review Manager 5.3. RESULTS AND CONCLUSION: Compared with the control group, electrical muscle stimulation significantly increased concentric contraction peak torque in exercise population (combined effect: weighted mean difference=8.23, 95% confidence interval: 6.71-9.76, P < 0.000 1), and the effect was most obvious at the age of 20-22 years. Compared with the control group, electrical muscle stimulation significantly increased eccentric contraction peak torque in exercise population (combined effect: weighted mean difference=5.58, 95% confidence interval: 4.16-7.00, P < 0.000 01). The number of included experiments about isometric contraction peak torque was small and it was not suitable for meta-analysis. To conclude, electrical muscle stimulation training can effectively promote the concentric contraction peak torque and eccentric contraction peak torque of the exercise population, and the effect of electrical muscle stimulation as a training method on the muscle strength of exercisers needs to be explored in terms of indicators, ages and subjects.

Objective To compare three ultrasonic methods of transabdominal , transvaginal , and transperineal ultrasonogra-phy for the cervical length ( CL) in predicting the preterm birth .Methods The pregnancy women with threatened preterm labor in Hunan Provincial Hospital of Maternal and Child Health from January , 2012 to December, 2013 were chosen to measure the cervical length by sonography , and were randomly divided into three guoups ( 280 pregnancy women in each group ) , including Group Ⅰ( transabdominal ) , groupⅡ( transvaginal ) , and group Ⅲ ( transperineal ) .The cervical length and the pregnancy outcome were fol-lowed up.Results The acceptance rate of group Ⅱ(81.8%=229/280) was significantly lower than that of groupⅠ(100%=280/280)and group Ⅲ(99.3%=278/280)( P <0.05).The realization ratio of the cervix in group Ⅰ(85.0%=238/280) was signifi-cantly lower than that of group Ⅱ(98.7%=226/229) and group Ⅲ (98.2%=273/278) ( P <0.05).The preterm birth rate of 48.6%(18/37) in groupⅠ, 37.8%(28/74) in groupⅡ, and 37.1%(33/89) in groupⅢin the pregnancy women with CL <3 cm was significantly higher than the corresponding preterm birth rate of 17.9%(36/201) in groupⅠ, 13.2%(20/152)in groupⅡ, and 13.6% (25/184) in groupⅢin the pregnancy women with CL≥3 cm.The sensitivity of groupⅠ(33.3%=18/54) was significantly lower than that of group Ⅱ(58.3%=28/48) and group Ⅲ(56.9%=33/58).Conclusions The cervical length measured by ultra-sound is valuable in predicting preterm birth among the pregnancy women with threatened preterm birth .The transperineal ultrasonogra-phy is superior to transabdominal and transvaginal ultrasonography in predicting preterm birth , and is worth being popularized .

Objective To explore the relative factors of polycystic ovarian syndrome (PCOS) in infertile women.Methods Ninety-eight infertile women diagnosed PCOS at affiliated hospital of the Chinese People's Armed Force Logistic college from Jan.2008 to Dec.2012 were served as PCOS group.Two hundred and eighty infertile women with normal ovarian structure according to laparoscopic examination result were selected as control group.The general information,factors related infertile and laparoscopic examination of the two groups were recorded.Results Fifty-one cases (52.0％) in PCOS group were with menarche age earlier than 13 years old,higher than that of control group (113 (40.4％),x2 =4.03,P ＜ 0.05).Eleven cases (11.2％) in PCOS group were with abnormal menstruation cycle,higher than that of control group (12 (4.3％),x2 =6.12,P ＜ 0.05).The incidence of pelvic adhesions in PCOS group was lower than the control group(60(21.1％) vs.224(40.4％),x2 =13.70,P ＜0.05).Irregular menstruation cycle was risk factor of PCOS (OR=1.770,95％ CI:1.09-2.88,P =0.002).Conclusion Women with earlier menarche and irregular menstruation cycle should be paid more attention in terms of PCOS,early screening,discovery,prevention and treatment,so as to reduce the incidence of PCOS induced infertility and the long-term complications.

ObjectiveTo assess the microscopic features of alopecia areata(AA) by using in vivo confocal laser scanning microscopy(CLSM).MethodsBetween January 2010 and May 2011,26 male and 20 female patients diagnosed with AA were enrolled in this study.AA lesions and perilesional normal skin were examined by means of in vivo CLSM.Tissue specimens were obtained from the lesions and perilesional normal skin of 10 out of the 46 patients and subjected to routine histopathologic examination.ResultsThe number of hair follicles per unit area(cm2) was decreased in lesions of progressive AA and resting AA compared with normal perilesional skin(134.856 ± 18.301 and 147.159 ± 17.536 vs.301.613 ± 35.317,both P ＜ 0.05).Although the quantity of hair follicles increased in lesions of recovery AA((227.778 ± 16.861 )/cm2),but was still less than that in the normal perilesional skin (P ＜ 0.05).There was a lack of hair shaft in follicles,as well as an inflammatory infiltration in hair follicles,around hair follicles and capillaries in superficial dermis in lesions of progressive AA.The inflammatory infiltration was attenuated in lesions of resting AA.In lesions of recovery AA,the infiltration was further attenuated with an apparent growth of lanugos and terminal hairs.ConclusionsAs far as AA lesions are concerned,CLSM images are consistent with histopathological findings.CLSM may serve as a promising tool for monitoring efficacy and predicting prognosis based on hair growth cycle,hair follicle number,and inflammatory infiltration degree.
