Objective To introduce an improved method of continuous intradermal suture,and to evaluate its clinical efficacy for the closure of surgical incisions.Methods Eighty-two patients were enrolled in this study,including 37 cases of nevus,10 cases of basal cell carcinoma,16 cases of sebaceous cyst,6 cases of lipoma,8 cases of seborrheic keratosis,3 cases of dermatofibroma and 2 cases of depressed scar.All the patients were managed by simple surgical excision with the shortest length of postoperative incisions being 0.8 cm and the longest length being 12 cm.An improved method of continuous intradermal suture was used for the closure of all the postoperative incisions.Specifically,an absorbable thread with a small triangle needle in both ends was inserted through and pulled out from the dermal layer at one side of the incision,and then inserted through and pulled out from the dermal layer at the opposite side of the incision,which was repeated until the incision was entirely closed.Results Among the 82 patients,80 achieved primary healing,and 2 developed erythematous painful swelling at the incision site 2 days after the operation,which disappeared after symptomatic treatment for 5 days.During 3-6 months of follow-up,the incisions closed leaving a flat and smooth surface in 78 patients,and proliferative scar formed in 4 patients,which was obviously improved after local injection with glucocorticoids.No disruption of incisions was observed.Conclusion The improved method of continuous intradermal suture can be applied to the closure of skin defects in the face,neck,trunk and extremities with a favorable healing outcome and cosmetic result.

Objective:To explore the effect of continuous obstetric-pediatric cooperative nursing on anxiety, depression and the parenting sense of competence in NICU premature mothers.Methods:Totally 140 mothers of NICU preterm infants in hospital from January 2018 to December 2018 were selected and randomly divided into the control group and intervention group according to the method of random number table, and each group 70 cases. The control group received the routine nursing mode in obstetrics and paediatrics and the intervention group received the continuous obstetric-pediatric cooperative nursing based on routine nursing. To compare the anxiety level, depression level, the score of parenting sense of competence, hospitalization days of preterm infants, the outpatient rate and the readmission rate of preterm infants within 1 months of discharge between two groups.Results:The levels of anxiety and depression of the mothers of premature infants in the intervention group during hospitalization ,1 week after discharge and 1 month after discharge were (43.17±6.89), (8.96±2.67), (34.65±6.87), (7.65±1.92), (34.97±6.06), (6.29±1.54) points, lower than control group (47.03±8.06), (10.97±3.34), (45.44±7.72), (9.43±2.61), (41.46±7.26), (8.28±2.23) points, the differences between the two groups showed statistical significance ( t value was 2.331-6.097, P<0.05). The two dimensions of parenting efficacy and parenting satisfaction were (31.47±4.97), (43.38±4.21) points, which were higher than (25.91±5.42), (39.43±5.91) points of the control group, there were significant statistical differences among the two groups ( t value was -6.314 and -4.528, P<0.01). The hospitalization days of premature infants, outpatient and readmission rate within 1 month of discharge were (13.25±3.27) days, 8.57% (6/70), 2.86% (2/70), which were shorter or lower than (15.59±2.79) days, 24.29% (17/70), 12.86% (9/70) in the control group, the differences were statistically significant ( t value was 2.909, χ2 values were 6.295, 4.834, P<0.05). There were significant statistical differences among interaction effect, time effect and intergroup effect ( F values were 4.921-99.310, P<0.05). Conclusion:Obstetrical-pediatric cooperative nursing can effectively to lower the anxiety and depression level of preterm mothers, improve the parental competence, promote the mental health of preterm mothers, and ultimately shorten hospital days and decrease the rate of outpatient and readmission of premature infants, which is conducive to preterm infants′ rehabilitation.

Objective To investigate the effects of lower limb training at different intensities on the recovery of walking function after stroke.Methods Thirty-six stroke patients were randomly divided into a 40-minutes of training group,an 80-minutes of training group and a 120-minutes of training group.Because of three missing followup cases,the final numbers of cases were 12,11 and 10 cases respectively.All of the patients received lower limb training based on regular rehabilitation therapy,but at the three different intensities:40 minutes,80 minutes or 120 minutes a day,five days per week,for 4 weeks.Walking function was assessed using the Holden functional ambulation categories (FACs) and the Fugl-Meyer assessment (FMA).These were carried out before treatment,and after two and four weeks of treatment.Results Before treatment,the average FACs of the three groups were (1.83 ±0.94),(1.73 ± 1.01) and (1.80 ± 1.03) respectively.Their average FMA scores were (19.17 ±5.52),(23.00±4.71) and (19.40 ±7.90).After two weeks of treatment,the average FAC in the 120-minutes training group was (3.30 ± 0.48),significantly higher than in the 40-minutes training group.After four weeks the average FACs in the 40-minutes,80-minutes and 120-minutes training groups were (2.67 ± 0.65),(3.18 ± 0.60) and (3.80 ±0.42) respectively.The differences between the 120-minutes group and the 80-minutes group as well as between the 80-minutes group and the 40-minutes training group were statistically significant.The average FMA scores of the three groups after four weeks were (25.08±4.46),(28.64±3.56) and (25.90±5.19) respectively.All the differences were significant compared with pre-treatment.There were no significant differences in FMA scores among the three groups after two weeks or four weeks of treatment.Before treatment,the proportion of patients able to walk independently in the 40-minutes,80-minutes and 120-minutes training groups were 16.7％,18.2％ and 20.0％.After two weeks the proportions had risen to 33.3％,36.4％ and 100％ respectively,so the results in the 120-minutes training group were significantly better.After four weeks of treatment the proportions of the three groups were 58.3％,90.9％ and 100％.All these improvements were significant compared with pre-treatment,but when compared with the 80-minutes training group,neither of the others showed a significant difference.Conclusions Intensive training can accelerate the recovery of walking function of patients after stroke and promote their ability to participate in daily activities.

Background and purpose:A variety of measures are taken preoperatively to reduce the tumor size of stageⅠb2 bulky cervical cancer before surgery. Which one is safer and more effective, currently, there is no consensus. This article compared the effect in 3 different treatment methods (neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy and operation) on patients with stageⅠb2 bulky cervical cancer, and provided evidence for clinical decision. Methods:Retrospective analysis the clinical date of 133Ⅰb2 bulky cervical cancer patients, who received preoperative neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy and direct operation from Apr. 2006 to Oct. 2010 in our hospital. Results: The effective rates of neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy group were 91.8% and 92.5%, respectively, there was no statistical difference(P>0.05). The tumor size got smaller after treatment compared with the size before treatment (P<0.05);The pathological efifciency rates were 95.56%and 97.30%, respectively, the difference was not statistically significant (P>0.05). The bleeding volume of neoadjuvant chemo radio therapy group was significantly higher than those in the other 2 groups (158.9±50.7 vs 116.8±45.5, 123.1±30.2;P<0.05), the infection of immediate surgery group was more severe than the other 2 groups (P<0.05). The pairwise comparison of average operation time in neoadjuvant chemotherapy group, neoadjuvant chemoradiotherapy group, and the immediate surgery group, pairwise comparisons of neoadjuvant chemotherapy group and the immediate surgery group in bleeding, comparion of neoadjuvant chemotherapy group and neoadjuvant chemoradiotherapy group on postoperative infection, and the comparison of the 3 groups on pelvic organ injury and lymphocele, had no statistical difference(P>0.05);Pathological examination showed that vascular invasion in surgery group had statistical differences than other 2 groups (P<0.05), there was no patient with positive margin in the 3 groups, and the lymph node metastasis rates also had no statistical difference (P>0.05);Besides, there were no statistical difference on vascular invasion between the 3 groups (P>0.05);And on 3-year overall survival, disease-free survival there was no statistical difference between the 3 groups (P>0.05). Conclusion:Neoadjuvant chemotherapy can effectively reduce tumor size for patients with stage Ⅰb2 bulky cervical cancer before operation, it is better than direct surgery or preoperative chemoradiotherapy in improving the resection rate, and reducing postoperative pathological positive rate, and infection. Neoadjuvant chemotherapy can improve the pathological complete remission rate. The combination of radiation and chemotherapy might produce synergistic effect on huge cervical tumor, but it can’t improve the survival rate. Therefore, neoadjuvant chemotherapy is the best choice for the stageⅠb2 cervical cancer patients. Therefore, a long-term follow-up or large sample randomized controlled trials is necessary to assess the prognosis of preoperative neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy.

Objective To compare theshort-term efficacy and safety between TP and PVB scheme chemoradiation for advanced cervical cancer. Methods Between January 2012 and January 2014, 187 Xinjiang uygur patients with advanced cervical cancer (stageⅡb to Ⅳa) who received concurrent chemoradiotherapy in Xinjiang medical university affiliated tumor hospital were analyzed. A1l cases were divided into two groups receiving radiotherapy concomitant (n = 104), PVB group (n = 83). Theshort-term efficacy and toxicity was evaluated four weeks aftertreatment. Results For squamous cell carcinomas, the response rates were 85.9% and 73.5% in TP and PVB group respectively (P > 0.05). For Non-squamous cell carcinomas (adenocarcinoma and adenosquamous), the response rates were 75.7% and 40% in TP and PVB group respectively (P < 0.05). B one marrow suppression, neurotoxicity, gastrointestinal reactionwere significant different between two groups (P <0.05). Liver and kidney functiondisorder, blood cellsreduction, and radiation damagewere not significantly different (P > 0.05). Conclusions For cervical squamous cell carcinomas, theshort-term efficacy of two chemotherapy regimens is similar while forNon-squamous cell carcinomas, TP regimengroup is superior toBone marrow suppression and neurotoxicity in TP regimengroup is significantly higher than PVB group (P < 0.05), while gastrointestinal adverse reaction lower than PVBgroup.

Objective To assess the therapeutic effects of activated charcoal on the acute dichlorvos poisoning in rats. Method Thirty male clean grade Wistar rats were randomly (random number) divided into three groups: control group (group A, n = 10), single dose activated charcoal group (group B, n = 10) and multi-dose activated charcoal (group C, n=10). The rats of group A were suffered from 35 mg/kg dichlorvos exposure by oral without activated charcoal and senna. The rats of group B received 35 mg/kg dichlorvos exposure by oral with 175 mg/kg activated charcoal given immediately after dichlorvos exposure and 35 mg/kg senna given half an hour later. In the group C, 35 mg/kg dichlorvos was given to rats by oral with 175 mg/kg activated charcoal given immediately after dichlorvos exposure and 35 mg/kg senna given half an hour later and then every four hours. Blood samples were collected from the carotid artery at different intervals after exposure. DDVP concentration and total blood acetyl-cholinesterase activity were detected. Differences in serum DDVP concentration, Cmax, AUC (0→∞ ), MRT and acetylcholinesterase among three groups were calculated by using ANOVA. Results Serum DDVP levels in single dose group and in multi-dose group were significantly different from those in control group (P < 0.05). The DDVP levels in multi-dose group were significantly different from those in single dose group 4 hours after exposure (P < 0.05). The AUC and Cmax in activated charcoal treatment groups were significantly different from those in control group (P < 0.05). There were no significant differences in MRT among three groups. Fours hours after exposure to dichlorvos,the levels of serum acetylcholinesterase in rats of group B and group C were significantly different from that in rats of group A (P < 0.05), and there was no significant difference in acetylcholinesteras between group B and group C (P > 0.05). Another four hours later, no differences in acetylcholinesterase were found a-mong three groups (P > 0.05). Conclusions The peak concentrations of dichlorvos in blood are lower in group B and group C, and the blood acetylcholinesterase inhibition is quelled by activated charcoal. Therefore, the effects of multi - dose of activated charcoal is better than that of single dose of activated charcoal.

OBJECTIVE:To observe the efficacy and safety of doxofylline combined with ceftazidime in the treatment of elder-ly patients with chronic emphysema. METHODS:Data of 78 elderly patients with ceftazidime was collected and divided into single drug group(31 cases)and combined medication group(47 cases)according to different treatment methods. All patients adopted flu-id infusion,oxygen inhalation and nutrition support. Based on it,single drug group received 0.05 g Doxofylline injection,once ev-ery 12 h. Combined medication group additionally received 1.0 g Ceftazidime for injection,once every 12 h. If the symptoms were out of control,20 mg prednisone was given,twice a day. The courses of 2 groups were 10 d. Total efficacy,pulmonary functions [maximum mid-expiratory flow(MMEF),1s forced expiratory volume percent predicted(FEV1%),peak expiratory flow(PEF)] before and after treatment,American Concise Health Survey Questionnaire(SF-36 scale)(QLS)and the incidence of adverse reac-tions in 2 groups were observed. RESULTS:The total effective rate in combined medication group was significantly higher than sin-gle drug group,the difference was statistically significant (P<0.05). Before treatment,there was no significant difference in MMEF,FEV1%,PEF and QLS scores between 2 groups(P>0.05). After treatment,MMEF,FEV1%,PEF and QLS scores in 2 groups were significantly higher than before,and combined medication group MMEF,FEV1%、PEF were higher than single drug group,the difference was statistically significant (P<0.05),but there was no significant difference QLS scores in 2 groups(P>0.05). And there was no significant difference in the incidence of adverse reactions in 2 groups (P>0.05). CONCLUSIONS:Based on conventional treatment,doxofylline combined with ceftazidime shows better efficacy than doxofylline alone in the treat-ment of elderly patients with chronic emphysema,it can improve pulmonary functions,with better safety.

Objective To investigate the impact of preload fasting and meal replacement in patients with metabolic syndrome.Methods A total of 92 subjects with metabolic syndrome were enrolled in the study.They were assigned into the preload fasting group (PFG),the meal replacement group (MRG),and the control group (CG) for 12-weeks intervention.Special dietary with 100 kcal was provided 30 min before each meal in the PFG,and while in the MRG the same dietary was taken just before each meal and the amount of meal was reduced appropriately.The subjects in CG took meals as usual.Body mass index,waist circumference,and insulin resistance were assessed.Satiety situation was investigated by the scale.Results After 12 weeks,improvement were found in fasting insulin(-3.29 mU/L) and waist circumference (-4.04 cm) in the PFG and significant difference was shown compared to the CG (P＜0.05).Satiety index in the PFG was the most significant among the three group.Conclusion Preload fasting is helpful in improving insulin resistance,reducing waist circumference,and enhancing satiety.

Objective: To evaluate the effect of functional training on the improvement of Cobb Angle, ATR and quality of life in adolescent idiopathic scoliosis. Methods: Database of CNKI, WanFang, WeiPu, Web of Science, PubMed were reconnoitered for the purpose of research articles of Interest. Literature was screened according to the inclusion criteria, randomized controlled trials (RCTS) were collected and Cochrane risk bias assessment methodology quality was used, and Revman 5.3 software was used to conduct combined effector subgroup analysis on outcome indicators (Cobb Angle, ATR, SRS-22 patient questionnaire). Results: A total of 10 RCT (398 AIS patients) were included in the study. There were two high , five moderate and three low quality studies, respectively. Compared with other non operative treatments, functional training could reduce Cobb horn in patients, MD = -6.56 (95% CI =-7.30--5.83, P <0.01, I 2=0). Further subgroup analysis showed that there were no statistically significant differences in effect size between the subgroups of Cobb Angle, age, intervention period and control method at the time of inclusion ( P >0.05). Compared with the non intervention blank group, the functional training group could reduce the Cobb Angle of patients ( MD = -5.25 , 95% CI =-8.27- -2.98 , P < 0.01 ), with high heterogeneity ( I 2=61%). Effect on angle of trunk rotation(ATR):functional training group could reduce patients ATR, MD =-1.91 (95% CI =-2.25--1.57, P <0.01, I 2=0). The impact on the quality of life:functional training of patients with SRS-22 questionnaire function, pain had no statistical significance ( P >0.05), and self image ( MD =0.64, 95% CI =0.53- 0.75 , P <0.01), mental health ( MD =0.44, 95% CI =0.15-0.74, P <0.01), satisfaction ( MD = 0.58 , 95% CI =0.11- 1.06 , P = 0.02 ) were statistically significant. Conclusion Functional training can not only reduce the Cobb Angle and ATR of AIS patients, but also improve the quality of life in terms of self image, mental health and satisfaction of the patients. However, due to heterogeneity and bias, more high quality studies are needed to verify.

Objective To investigate the expression of regulators of G protein signaling(RGS), including RGS2, RGS3 and RGS4 in OLETF rats, as well as the effects of metformin on these expressions. Methods LETO rats were used as control group. Eight-week-old male OLETF rats were assigned to two guoups randomly:model and trial(metfomin dose during 8~(th) to 22~(nd) weeks:300mg kg~(-1)·d~(-1);during 23rd to 28th weeks:400 mg·kg~(-1) ·d~(-1))groups. Expressions of RGS mRNA in aorta and heart werequantified by real-time PCR. Results RGS2, RGS3 and RGS4 mRNA of the thoracic aorta and left ventricle were significantly higher in model group than in control group (P<0.01). Compared with model group, metformin significantly reduced their mRNA in trial group (P<0.01). Conclusions Upregulation of RGS2, RGS3 and RGS4 mRNA expression in the thoracic aorta and left ventricle of OLETF rats is in correlation with cardiovascular lesions; while downregulation of their expression is in correlation with the action of metformin.
