Objective To investigate the clinical value of King's College Hospital Criterion (KCH),Canadian Waitlisting Algorithm Criterion (CanWAIT) and Japanese Liver Transplantation Criterion (JLT) in predicting the prognosis of the patients with chronic severe hepatitis in China. Methods Fifty-five patients with chronic severe hepatitis were classified respectively by the three liver transplantation criteria.Those who were in line with the criterion were ascribed the matched criteria group (MCG),while those who were not in line with the criterion were ascribed the unmatched crite ria group (UCG).The end point of observation was the 90th day after their admission.The survival time and the mortality were compared between the MCG and UCG.The predictive ability for each cri- terion and their correlation with the clinical stages of chronic severe hepatitis were analyzed.Results Seventeen cases accorded with KCH and CanWAIT,while 38 cases did not accord with KCH and CanWAIT.The median survival time (MST) and their mortality in MCG group were 17.5 days and 100.0% respectively,while those in UCG group were 69.2 days and 34.2% respectively.Twenty- one cases accorded with JLT,while 34 cases did not accord with JLT.The MST and their mortality in MCG were 17.7 days and 95.2% respectively,while those in UCG group were 75.2 days and 29.4% repsectively.There were significant differences in MST and mortality between MCG group and UCG group with the 3 criteria (P

Objective To report the experience on the modified Abb? flap for correction of mild tightness of the corrected cleft lip deformity. Methods Forty-two patients with a mild or moderately tight lip deformity after primary unilateral cleft lip repair were performed a modified Abb? flap for correcting tight upper lip. The operative technique was that the pocket was creased for the vermilion tubercle by splitting the lip. The skin was incised several millimeters beyond the vermilion-skin border and was moved laterally for a distance equal to the breadth of the vermilion tubercle. The orbicularis oris muscle and the full length of the upper lip vermilion were incised. By releasing the tension, the slight concavity, expressed in profile by the slight pout which a normal upper lip had in cross section, was obtained. The Abb? flap that was taken from the central portion of the lower lip vermilion, was designed to repair the vermilion tubercle and the Cupid's bow. The flap was approximately 8 mm in width. The full length of the lower lip vermilion and the orbicularis oris muscle were incorporated. A ting portion of skin was included, which facilitated closure of the donor site, The flap, based on the labial vessels, was rotated 180?and sutured into the created defect of the upper lip. The pedicle was divided 10 days after operation. Results Forty-two patients all showed an obvious Cupid's bow, Cupid's bow peak, the median tubercle and the height and width of the upper lip. The scarring of the base of the nose was not obvious. Conclusion Use of modified Abb? flap to reconstruct the contour of the upper lip is successful in patients with cleft lip.

Objective:To explore the intervention effect of proteasome inhibitor MG132 in rats with collagen-induced arthritis(CIA),which resembles human rheumatoid arthritis(RA).Methods:Forty-eight female SD rats were randomly divided into three groups,including blank control group,CIA model group and MG132-treated group.There were sixteen rats in each group.Rats in CIA model group and MG132-treated model group were injected with type Ⅱ collagen to established CIA rats.21 days after the initial immunization,the rats in the MG132-treated model group were injected subcutaneously with 1 mg/kg MG132 once daily for 2 weeks.42 days after the initial immunization,the change of paw-swelling and the arthritis scores were determined.The synovial pathology examination was performed with HE staining.The 20S proteasome activity in synovial tissue was measured by fluorescence substrate assay.The expression of NF-κB/p65,IκBα in synovial tissue were analyzed by Western blot.Results:Proteasome inhibitor MG132 significantly attenuated the severity of arthritis and histopathological changes in CIA rats.Compared with the blank control group,the 20S proteasome activity was increased significantly in the CIA model group(P<0.05),and decreased after injection of MG132.Compared with CIA rats,the expression of NF-κB/p65 significantly decreased in rats treated with MG132(P<0.01).Compared with the blank control group,the expression of IκBα protein decreased in CIA model group.After injected with MG132,the protein was significantly increased(P<0.01).Conclusion:The proteasome inhibitor MG132 may attenuates the severity of arthritis and histopathological changes in CIA rats.These effects may be mediated through the inhibition of NF-κB activity.

Objective To optimize the extraction process of volatile oil and inclusion preparation of hydroxypropyl-β-cyclodextrin from compoundJinling Sini Siwu Shixiaosan Granules.Methods The orthogonal approach of L9 (34) was applied to investigate the volume of volatile oil extraction by 3 factors to obtain the optimum extraction conditions. With inclusion rate of volatile oil and yield of inclusion compound as comprehensive evaluation indexes, the optimum preparation conditions were discussed. The characterization of this prepared inclusion was analyzed by TLC.Results The optimum extraction conditions were as follows:the crude medicine with medicinal powder was shattered into 20 meshes;8 times the amount of water was added and was extracted for 8 h. The best inclusion conditions were as follows:the proportion of volatile oil to HP-β-CD was 1∶6, with inclusion temperature of 30℃, grinding time of 2 h. Analysis results of TLC showed that stable inclusion compound was formed from volatile oil and HP-β-CD.Conclusion The optimized extraction process and inclusion preparation are with stable quality and high feasibility.

Objective To investigate the association between (beta-parvin) PARVB gene rs5764455 polymorphism and susceptibility to non-alcoholic fatty liver disease (NAFLD). Methods A total of 230 patients with NAFLD (NAFLD, n = 230) and 230 control subjects (control, n = 330) were genotyped by PCR and direct sequencing. Clinical information was detected and compared in different groups. Genotypic frequency and gene frequency distribution in the two groups and relative risks to NAFLD susceptibility were assessed statistically , respectively. Results No statistical differences were observed between PARVB gene rs5764455 genotypic frequency with gene frequency distribution and the two groups, respectively (Genotypic frequency χ2 = 0.182, P = 0.913; gene frequency χ2 = 0.180, P = 0.672). Comparing C/T + T/T genotype carrier with C/C genotype carrier, there were no differences concerning the relative risks to NAFLD susceptibility (OR = 1.266, P =0.178;adjusted OR =1.631, P =0.096) before and after adjusting body mass, BMI and so on. In the latter group, there are significant differences in the increases of body mass, BMI, TG, ALT and AST (P < 0.05). Conclusion Non-relationship was observed between PARVB gene rs5764455 polymorphism and the risk of NAFLD in Qingdao Han Chinese.

Objective To evaluate the clinical repair effects of the reconstruction of different vermilion tubercle after primary cleft lip repair.Methods According to the tight lip deformity and dif ferent degrees of defect of the vermilion tubercle and exposing the gums and the crown of the anterior incisors,178 patients after primary repair of the cleft lip from Department of Oral and Maxillofacial Surgery of Xiangya Hospital,Central South University were classified into the tight lip deformity and four grades of whistling deformities.According to different deformities and defects,the different operative techniques were used as follows:classic Abbé flap and modified Abbé flap were used for tight lip deformity;the bilateral advanced myomucosal flaps of lip were used for the grade Ⅰ;modified Abbé flap was used for repairing the grade Ⅱ and the grade Ⅲ whistling deformities;for grade Ⅳ whistling deformity,we mainly used classic Abbé flap.The follow-up after operation was performed,all patient's Cupid's bow,Cupid's bow peak,the vermilion tubercle and the height and width of the upper lip were observed.The scarring of the upper lip was also observed.Results The follow-up after operation was performed from six months to ninteen years,all the 187 patient's anatomical structures of the upper lip were nearly normal after recovery.The all patients showed an obvious Cupid's bow,Cupid's bow peak,the vermilion tubercle and the height and width of the upper lip.The relation of the upper lip and lower lip was harmonious.The scarring of the upper lip was not obvious 2 years after operation.Conclusions The different repair methods are chosen to repair different deformity and defect that has an important clinical value.

Objective To investigate epidemiological characteristics and trends of gonorrhea in China, and to provide a scientific basis for the development of control strategies. Methods An epidemiological study was performed on gonorrhea cases reported from 31 provinces, autonomous regions or municipalities directly under the central government between 2000 and 2014. Results The reported incidence rate of gonorrhea decreased from 22.92 per 100 000 in 2000 to 7.25 per 100 000 in 2014, with the average annual rate of decrease being 7.89%. There was a significant difference in the incidence of gonorrhea between different regions. The regions with the highest incidence rate of gonorrhea were Yangtze River Delta region(Zhejiang, Shanghai, Jiangsu)and Zhujiang River Delta region(Guangdong, Guangxi, Hainan), followed by northwest China (Xinjiang, Ningxia, Inner Mongolia). The incidence of gonorrhea was higher in males than in females, and the average male/female ratio increased from 1.96 ∶ 1 in 2000 to 4.52 ∶ 1 in 2014. The population aged 20 - 44 years showed high incidence of gonorrhea, and the highest incidence rate of gonorrhea was observed in the age group 25 - 29 years in both men and women. The incidence of gonorrhea decreased in all the age groups from 2000 to 2014 except the age group 15 - 19 years with an annual growth rate of 4.18%. Of 20 occupations, peasant workers accounted for the highest proportion (26.00%)of reported gonorrhea cases, and the number of reported gonorrhea cases showed a decreasing trend in all the occupations. Conclusions Gonorrhea remains a major public health issue in China, and effective measures based on epidemiological features are urgently needed to control gonorrhea.

Objective To investigate the clinical features of malignant conversion of oral submucous fibrosis (OSF) and the application value of polyflaps perforator flaps in its surgical treatment.Methodis Ten patients who suffered from malignant conversion of OSF underwent simultaneous multiple defects reconstruction using polyflaps perforator flaps after radical tumor resection from August 2012 to October 2014.The fibrous bands leading to severe trismus near the pterygomandibular ligament as well as other intraoral lesions with malignant tendency were also resected besides from the known carcinoma.Patients with synchronous multiple primary cancers underwent radical resection and neck dissection of all other malignant lesions.The flaps were cut and tailored between adjacent perforators according to the amount and size of defects,forming several independent paddles for each defect reconstruction.Results Twenty-two defects were formed in 10 patients with malignant conversion of OSF.All of them were repaired with polyflaps anterolateral thigh (ALT) perforator flaps,including 8 cases of bipaddled ALT flaps and 2 cases of tripaddled ALT flaps.The total size of the flaps ranges from 3 cm ～ 8 cm × 6 cm ～ 24 cm,and the pedicle length ranges from 5 ～ 12 (9.7 ± 2.1)cm.Thirty-five perforator vessels were dissected,and each paddle included 1.6 perforators on average.All flaps survived after transplantation,and only 1 patient had infection of the neck incision.Post-operative adjuvant radio-chemotherapy was applied in 2 patients.All patients showed satisfactory accepting-site morphology with good speech function and swallowing recovery,and their trismus was improved during 6 to 30 (11.6 ± 3.7) months.One patient died from lung metastasis 10 months after the surgery while local recurrent or metastasis did not occur in others.The donor sites were closed primarily without skin-grafting,leaving no obvious surgical donor-site complications.Conclusions Polyflaps perforator flaps can reconstruct multiple and sizable complicate defects,increase month opening by one stage operation.They are worth being applied in surgical treatment of malignant conversion of OSF.
