Objective To explore the reliability and validity of the simplified Chinese version of the Oswestry disability index (SCODI) and the curative effect of community-based rehabilitation for patients with lumbar disc herniation (LDH). Methods 165 patients with LDH received community-based rehabilitation according to the severity of their LDH. Before treatment and after 3 months, the SCODI, the Roland-Morris disability questionnaire (RMDQ) and a visual analogue scale (VAS) were used to evaluate the effects. The reliability and validity of the SCODI was thus tested. The reliability analysis included internal consistency as measured by Cronbach's coefficient,and test-retest reliability as measured by an interclass correlation coefficient (ICC). The validity analysis used Spearman's correlation coefficient (for concurrent efficacy validity) and factor analysis (for construct validity). The correlation between SCODI, RMDQ and VAS results was analyzed. Results There was statistically significant functional improvement and better QOL in LDH patients after community-based rehabilitation. The SCODI showed good validity and reliability. There was significant correlation among the SCODI, RMDQ and VAS results. Conclusion Community-based rehabilitation can significantly alleviate symptoms for patients with LDH and improve their QOL.The SCODI is a reliable and valid instrument for measuring the curative effect of community-based rehabilitation on patients with LDH.

Epiretinal membrane (ERM) is a relatively common macular disease that forms along the surface of the internal limiting membrane (ILM) of the retina to some reason.The pathogenesis is not clear.Microincision vitrectomy surgery has been confirmed as a minimally invasive and very safe modality of treatment.Deciding when to perform a vitrectomy can be difficult.There are many factors which can affect the postoperative visual acuity,such as age,the thickness of macular,integrity of photoreceptor inner segment/outer segment (IS/OS) junction.

Objective : To understand the prevalence of overweight and obesity, and the influencing factors among students aged 7-22 years in Zhejiang Province. Methods : Stratified random cluster sampling was used to randomly select students aged 7-22 years in 11 prefectures of Zhejiang Province in 2019. Height and weight were measured. The general information, dietary habits and living habits of students were collected using the Student Health Status and Influencing Factors Questionnaire. The multivariate logistic regression model was used to analyze the influencing factors of overweight and obesity. Results : A total of 33 800 respondents were included, 7 685 (22.74%) were overweight/obese, 4 729 ( 13.99% ) were overweight, and 2 956 ( 8.75% ) were obese. The multivariate logistic regression analysis suggested that boys ( OR=2.059, 95%CI：1.949-2.175), not living on campus( OR=1.306, 95%CI: 1.214-1.405), history of alcohol consumption ( OR=1.158, 95%CI：1.083-1.238 ), average daily consumption of sugar-sweetened beverages in the past week ( less than once, OR=1.214, 95%CI: 1.103-1.336; once and more, OR=1.431, 95%CI: 1.259-1.626 ), average daily consumption of fries in the past week ( less than once, OR=1.171, 95%CI: 1.065-1.288; once and more, OR=1.266, 95%CI: 1.102-1.454 ), and average daily consumption of sweets in the past week (less than once, OR=0.727, 95%CI: 0.658-0.802; once and more, OR=0.504, 95%CI: 0.444-0.572) were associated with overweight and obesity in students. Conclusion The prevalence rates of overweight and obesity among students aged 7-22 years in Zhejiang Province are 13.99% and 8.75%, respectively, which are associated with boys, not living on campus, and consumption of sugar-sweetened beverages, fries, sweets and alcohol.

Objective:To summarize and analyze the clinical characteristics of different treatment in children with esophageal foreign bodies.Methods:This study collected 246 children with esophageal foreign bodies in our hospital from January 2016 to January 2020, which was divided into endoscopic group and operative group.The general and clinical data of children treated with different treatment were collected and statistical analyzed.Results:There were 222 children in endoscopic group and 24 children in operative group, respectively.The rate of surgery was 9.75%.There were no significant differences in gender and location of esophageal foreign bodies.However, the average age of operative group was(2.92±2.67) years, which significantly younger than that in endoscopic group(4.12±3.37)years( P=0.049). The residence time in operative group(median 29.10 h)was remarkable longer than that in operative group(median 11.80 h)( P<0.001). The proportion of sharpness(50.00%) and corrosive(45.83%) foreign bodies in operative group were more than those in endoscopic group[16.22% and 8.11%( P<0.001)]. Moreover, the occurrence rate of major complication in operative group was 83.33%, which was dramatically higher than that in endoscopic group(0.90%)( P<0.001). Conclusion:The younger and longer residence time of esophageal foreign bodies in children contribute to the rate of operative treatment.Additionally, the sharpness and corrosive foreign bodies increase the risk of surgery and serious complications.

Objective:To analyze clinical and histopathological characteristics of infantile congenital melanocytic nevi (ICMN) .Methods:Clinical and pathological data were collected from 126 infants with confirmedly diagnosed congenital melanocytic nevi in Department of Dermatology, Xijing Hospital from January 2015 to January 2020, and were retrospectively analyzed. Chi-square test was used for comparisons of enumeration data.Results:Among the 126 patients with ICMN, 68 were males and 58 were females; 109 (86.5%) presented with skin lesions at birth; 73 (57.9%) were 2 - 3 years old at the first clinic visit. The skin lesions occurred on the head and face (76 cases, 60.3%) , trunk (24 cases, 19.1%) or extremities (26 cases, 20.6%) . There were 36 (28.6%) patients with small congenital nevi, 68 (54.0%) with M1-type medium-sized nevi, 13 (10.3%) with M2-type medium-sized nevi and 9 (7.1%) with giant nevi. Of 126 cases of ICMN, 121 (96.0%) had solitary lesions, 5 (4.0%) had multiple lesions, 44 (34.9%) had nevi with coarse hairs, 15 (11.9%) had nevi complicated by papules or hyperplastic nodules, and 6 (4.8%) had satellite lesions. Pathological subtypes included compound nevus (120 cases, 95.2%) , intradermal nevus (4 cases, 3.2%) , and junctional nevus (2 cases, 1.6%) . Under the microscope, the depth of the skin lesions was < 1 mm in 38 (30.1%) cases, 1 - 2 mm in 61 (48.4%) and > 2 mm in 25 (19.8%) , and 45 (35.7%) cases showed nevus cells infiltrating the subcutaneous fat layer or deeper tissues. Among the 126 ICMN lesions, common pathological features included nevus tissue maturation (100%, 2 cases of junctional nevi were excluded) , pigment granules in the stratum corneum (53 cases, 42.1%) , disordered/asymmetric distribution of nevus cells (80 cases, 63.5%) , scattered epidermal nevus cells (91 cases, 72.2%) , pagetoid spread of epidermal nevus cells (67 cases, 53.2%) , melanophages in the dermis (71 cases, 56.4%) , and nevus cells distributed along hair follicles/sebaceous glands (82 cases, 65.1%) . Special pathological features included nevus cells embedded in the vascular/lymphatic vessels (42 cases, 33.3%) , nevus cell lysis (45 cases, 35.7%) , fibromatous changes (25 cases, 19.8%) , involvement of the arrector pilli muscles (31 cases, 24.6%) , and mast cell infiltration (30 cases, 23.8%) . Pathological patterns of ICMN with different clinical features: the incidences of infiltration depth > 2 mm, pigment granules and columnar pigment granules in the stratum corneum were significantly higher in the giant nevi than in the small and medium-sized nevi ( χ2 = 7.93, 10.76, 5.89 respectively, all P < 0.05) ; the incidences of infiltration depth > 2 mm, epidermal spongiosis with scattered nevus cells, nevus cell nests distributed along the hair follicles/sebaceous glands, fibromatous changes and mast cell infiltration were significantly higher in the skin lesions with coarse hairs than in those without ( χ2 = 28.29, 8.11, 6.22, 7.92, 8.19 respectively, all P < 0.01) ; the incidences of pagetoid spread of epidermal nevus cells and atypical nevus cells were significantly higher in the skin lesions with papules/hyperplastic nodules than in those without papules/hyperplastic nodules ( χ2 = 4.92, 6.30 respectively, both P < 0.05) . Conclusions:The clinical and histopathological characteristics of ICMN are unique, and atypical nevus cells are common in ICMN. The diagnosis and treatment of ICMN need to be based on the combination of clinical and pathological characteristics.

Objective To construct the lentivirus carrying human ?-catenin-EGFP(enhanced green fluorescent protein)and observe its expression in human follicle stem cells.Methods The ?-catenin gene sequence was amplified by RT-PCR from extraction of total RNA of human vascular endothelial cells.TA cloning technique was utilized to acquire gene subcloned pUCm-T-?-catenin.After transformation reaction,candidate clone was further analyzed by PCR and gene sequencing.Then the plasmid was transfected into FT293 cells.After identification by Western blotting,the plasmid was transfected into FT293 cells again for packaging.Infection titer was monitored by green EGFP expression.The expression of ?-catenin-lentivirus in human follicle stem cells were observed under inverted fluorescence microscope.Results The ?-catenin gene was cloned into the lentivirus successfully.The high expression of green fluorescence protein in FT293 cell line was found under fluorescent microscope.Viral titer checked by real-time PCR was about 2.0?108 TU/mL.When the multiplicity of infection(MOI)was 10,the infection efficiency of ?-catenin-lentivirus in human follicle stem cells was nearly 80% after infection 48 h around.After 3 weeks of continuous observation,we found the infection efficiency still keeping in the range of 80%-90%.Conclusion The lentivirus expression vector for ?-catenin was successfully constructed.It can steadily infect human follicle stem cells and the infection efficiency is considerable high.

OBJECTIVETo observe the effect of activation of aldehyde dehydrogenase 2 (ALDH2) by ethanol on the expression of c-Jun N-terminal kinase (JNK) in the kidney of diabetic rats.

METHODSEightheen healthy male SD rats were randomly divided into 3 groups (n = 6): normal control group, diabetes group and ethanol + diabetes group. After 8 weeks, 24 h urine samples from rats were collected to detect urinary protein content. The kidney was isolated and the ratio of kidney weight/body weight (index of kidney weight) was detected. The levels of fasting blood glucose, glycosylated hemoglobin serum urea nitrogen and serum creatinine were measured. Morphological changes of renal tissue were observed by optical microscope. The protein expressions of ALDH2 and JNK in renal tissue were detected by Western blot.

RESULTSCompared with the normal control rats, the levels of fasting blood glucose, glycosylated hemoglobin, serum urea nitrogen, serum creatinine and the index of kidney weight were increased markedly in diabetic rats. The expression of ALDH2 protein was decreased, while p-JNK, JNK protein expressions and the ratio of p-JNK/JNK were increased. The morphological observation was shown that the amount of glomerular mesangial matrix were increased, basement membrane were thickened and capillary lumen were narrowed. However,in ethanol + diabetes group, renal function was improved and the damage of renal structure was attenuated. The expression of ALDH2 protein was increased, while p-JNK, JNK and the ratio of p-JNK/JNK were decreased.

CONCLUSIONEnhanced ALDH2 expression can protect kidney in diabetic rats, which may be relevant with inhibitting the activity of JNK pathway.
