Objective To observe the clinical effect and safety of propranololand imiquimod therapy for infantile hemangiomas of proliferative phase.Methods A total of 53 infantile patients with hemangiomas of proliferative phase that were treated in our department were collected.According to patient's condition,the patients were classified into treatment group and observation group.The treatment group consisted of 34 patients received propranolol and imiquimod treatment,and 19 cases belonged to the observation group.The changes of tumor were compared between the treatment group and the observation group.Pre-therapeutic and post-therapeutic heart rate,blood pressure,blood glucose were monitored in the treatment group,so were in post-treatment.Results After 6 months,the effective rate was 97.1％ (33/34) in treatment group,and the effective rate was 57.9％ (11/19)in observation group.There was significant difference between treatment group and observation group in effective rate (P＜0.05),and so did blood pressure and heart rate after medication in the treatment group,but not in blood glucose,heart rate six hours after medication (P＞0.05).Conclusions Propranolol and imiquimod therapy has a certain inhibitory effect on infantile hemangiomas of proliferative phase.Propranolol and imiquimod are safe in patients with infantile hemangioma,and adverse reactions are mild.

Objective To investigate the effects of rapid colloid and crystalloid infusions on the plasma concentration of propofol( Cp) during target-controlled infusion.Methods Thirty-six patients were randomly assigned to three interventions(12 patients per group).At least 30 min after the start of propofol infusion,the hydroxyethyl starch solution group(HES)received HES of 24 mL/(kg· h),on the former 20 min,the sodium acetate Ringer’s injection group(AR)received AR of 24 mL/(kg· h),while HES group and AR group of later 20 min and the control group of whole course received AR of 2 mL/(kg· h).The plasma concentrations of propofol were recorded per 2 min and a half.The cardiac outputting,blood volume and clearance of indocyanine green were measured by pulsed dye density analyzer,the effective hepatic blood flow( EHBF) were obtained.Results The varying of Cp with time showed a significant treatment factor(F[2,33] =14.14,P<0.001)and time factor(F[16,528] =10.37,P<0.001)and interaction between the above factors(F[32,528] =2.82,P <0.001) by ANOVA for repeated measurement;the difference of Cp among each group,Cp in HES group was significantly lower than AR group(5-40 min)or control group(10-40 min),with significant difference(P<0.05).The varying of EHBF with time showed a significant treatment factor(F[2,28] =3.68,P=0.038)and time factor(F[2,56] =5.37,P=0.007)and interaction between the above factors(F [4,56] =3.67,P=0.010);while there was no significant difference in other groups.Conclusion Rapid HES infusion increases the effective hepatic blood flow,resulting in a decrease of propofol concentration during target-controlled infusion.Rapid HES infusion should be used cautiously as it may decrease the depth of anesthesia.

Objective To observe the effect of restrictive transfusion in colon cancer surgery in elderly patients on postoperative VAP (ventilator-associated pneumonia). Methods Forty cases of elderly patients with colon cancer intending to undertake surgery were randomly divided into restrictive transfusion group (group R) and standard transfusion group (group S) with 20 cases in each group. In group R, patients were administered one third of accumulative fluid loss in the first 60 minute, then the infusion rate were 4 mL/(kg·h) and central venous pressure was maintained at 5 ~ 7 cmH2O. In group S, rate of fluid administration = CVE + deficit +maintenance + loss + third space. Blood gas index including lactic acid and volumes of fluid administered, blood loss, urine volume and thoracic fluid count (TFC) were recorded in the operation. Clinical pulmonary infection score(CPIS) was recorded respectively before operation, 1 day, 3 day, 7 day after operation to evaluate the risk of VAP. Results Compare with those in group S, there were significantly less TFC and intraoperative volumes of fluid administration in group R. The CPIS was significant lower at day1, day3, day7 after operation in group R. There was no significant difference in MAP, HR, CO and urine volume between two groups. Conclusions In colon cancer surgery for elderly patients, restrictive transfusion can maintain hemodynamic stability, ensure the tissue oxygenation, reduce conjunction edema, shorten the recovery and hospital stay and reduce the incidence of VAP.

Objective To investigate the role of IL-13 in the patients with acute and chronic urticaria. Methods In 22 patients with acute urticaria, 20 patients with chronic urticaria and 19 normal controls, the levels of IL-13, IL-4 and IFN-? of peripheral T lymphocytes were measured by flow cytometry. The serum concentrations of IL-13 and total IgE were tested by ELISA. Results The results of flow cytometry showed that the level of IL-13 of the patients with acute urticaria was significantly higher than that of the normal controls (P

Objective To investigate the methods and effects of different flaps for repair of high energy injury-induced soft tissue wound of the heel.Methods From January 2002 to June 2012,the patients including 12 males and 9 females aged 18-57 years (mean,32 years) underwent heel soft tissue defect reconstruction.Causes of injury were traffic injury in 11 case and mechanical injury in 10 cases.Dimension of soft tissue defect ranged from 5 cm × 3 cm to 8 cm × 6 cm.Soft-tissue defect was repaired with sural neurovascular flaps at the posterolateral heel in 9 cases (Group A),with posterior tibial artery flaps at the posterolateral heel in 5 cases (Group B),and with medial plantar flaps at the loading area of heel in 7 cases (Group C).Sensory recovery and two point discrimination motion of the ankle joint were observed and compared among groups 12 month after operation.Heel pain was observed during weight bearing and joint activity was evaluated using the visual analogue scale (VAS).Results All the flaps survived,except for one with epidermal necrosis over the distal part,which healed after partial changing medication.Duration of follow-up was 12-24 months.There were no differences in the appearance,texture and contour between the flaps and recipient sites.Flaps showed no ulcer in the weight-bearing area and recovered their protective sense.Patients could walk normally after surgery.At postoperative 1 year,sensory recovery rate of the flaps in Groups A,B and C was 0,20％ and 100％ respectively (P ＜0.01).Appearance of the heel in all groups recovered to almost normal.Cases that could start nil weight-bearing exercise without pain accounted for 8 (89％) in Group A,4 (80％) in Group B,and 6 (86％) in Group C (P ＞ 0.05).While heel pain existed in weight-bearing exercise.Difference in VAS was significant among the three groups (P ＜ 0.05),but ankle range of motion was not (P ＞0.05).Conclusion Medial plantar flaps are suitable for tissue defect of 5-8 cm in length but sural neurovascular flaps and posterior tibial artery flaps should be considered for over 8 cm defect in order to elevate survival rate of the flaps and reconstruct limb function.

Objective To study the therapeutic effects of intermittent hypoxia therapy(IHT)in isolated systolic hypertension(ISH)patients with elevated cerebral blood flow velocity(Vp),and to explore the mechanisms involved.Methods Seventy-six ISH patients with increasing Vp and normal pulsatility index(PI)of the middle ce- rebral artery(MCA)were randomly divided into a therapy group and a control group.IHT was administrated in the therapy group,and air in the control group.The Vp and PI of the MCA and blood pressure(BP)were observed be- fore and after treatment.Results Vp and systolic blood pressure(SBP)were significantly reduced after IHT(P＜0.01)compared with the therapy group's scores betore treatment,but PI and diastolic blood pressure showed no sig- nificant difference.There was no significant change in BP,Vp or PI in the control group before or after treatment. Conclusion IHT has therapeutic effects on ISH by reducing Vp and moderating SBP.

Objective To identify interleukin 17 (IL-17) and B cell activating factor (BAFF) that could influence B cell biology by detecting the expression of BAFF in the serum and labial salivary glands from primary Sj(o)gren's syndrome (pSS) patients and to test the apoptosis rates of B cells cultured with Th17 cells which were transfected with IL-17-siRNA,BAFF-siRNA.Methods A total of 40 patients with pSS who were referred to the Department of Rheumatology and Immunology at Anhui Provincial Hospital from June 2011 to June 2012 were enrolled into this study.The expression of BAFF on salivary gland and serum from pSS patients and healthy controls were detected by ELISA and immunohistochemical examination (22 patients with pSS).Flow cytometry was used to detect B cell's apoptosis,BAFF and IL-17 interfered with amplified Th17 cells,and co-cultured with B cells.Immunoblot was used to detect supernatant antibody in 5 patients with pSS.Independent samples t test was used for statistical analysis.Results In all pSS specimens,infiltrating inflammatory cells expressed BAFF,so did some ductual cells,but acinar cells did not express these markers.There was no expression of BAFF in the controls.BAFF-positive cell numbers in the labial salivary glands of pSS patients with focal infiltrating lymphocytes were more than that with non-focal infiltrating lymphocytes (888±372 vs 164±161,t=5.94,P＜0.05),and the percentage of BAFF-positive lymphocytes over the total infiltrating lymphocytes in the salivary glands of pSS patients with focal infiltrating lymphocytes [(0.18 ±0.08) ％] was higher than those with non-focal infiltrating lymphocytes [(0.09 ±0.07) ％] (t =3.03,P＜0.05).The level of soluble BAFF in patients with pSS [(6.0±2.8) ng/ml] was significantly higher than the controls [(3.8±1.7) ng/ml,t=3.26,P＜0.05].BAFF or IL-17 transfected group,B cell apoptosis rate [(24± 5)％,(23±5)％] were significantly higher than the non-transfected group [(7±4)％],t=4.6,4.4; P＜0.05].And there was no significant difference when compared with cultured B cells (P＞0.05).Compared with the controls,no antibody could be detected in the supernatants.Conclusion BAFF may be involved in the process of local inflammatory damage of the pSS,it may have a synergistic effect with IL-17 on abnormal B cell function.

Objective: To investigate the difference in influencing factors for diabetes between urban and rural residents in Hefei City, so as to provide the basis for control and research of diabetes. Methods: The residents aged 18 years and older were selected using the stratified multistage random sampling method from 5 districts (counties) in Hefei City from August to December 2021. Demographic information, smoking, self-rated health status and sleep duration were collected through questionnaire surveys. Height, body weight and fasting blood glucose were measured. The crude prevalence of diabetes was calculated and standardized by age using China Statistical Yearbook 2022. Factors affecting diabetes were identified using a multivariable logistic regression model. Results: Totally 10 443 residents were investigated, including 6 386 urban residents (61.15%) and 4 057 rural residents (38.85%). There were 4 690 males (44.91%) and 5 753 females (55.09%). Diabetes were detected in 1 492 cases, with a standardized prevalence of 9.57%. The standardized prevalence of diabetes among urban and rural residents were 9.21% and 12.58%, respectively, and the difference was statistically significant (P<0.05). Multivariable logistic regression analysis showed that region, age, educational level, occupation, body mass index and self-rated health status were influencing factors for diabetes. Further analysis stratified by urban and rural area showed that, in addition to the above factors, gender and smoking were influencing factors for diabetes among urban residents, while sleep duration was the influencing factor for diabetes among rural residents (all P<0.05). Conclusions There are urban-rural differences in the prevalence of diabetes among residents in Hefei City, and the prevalence of diabetes is associated with age, educational level, occupation, body mass index and self-rated health status.
