Objective To compare the efficacy of supraclavicular approach and infraclavicular approach in ultrasound-guided brachial plexus block(BPB).Methods One hundred and twenty patients,ASA Ⅰ-Ⅲ,aged 18-80 yr,scheduled for upper extremity surgeries of both gender,were randomized into two groups(n =60):supraclavicular group(group SCB)and infraclavicular group(group ICB).The anesthetic mixture consisted of ropivacaine 0.375％ and lidocaine 1％ in equal volumes with epinephrine 1∶200 000,the total dose was 0.5 ml/kg.The block performance time,duration of anesthesia and success of anesthesia(surgery was accomplished without supplementary block)were recorded.A blinded observer assessed pinprick sensory block in the seven distal nerve territories(axillary,radial,musculocutaneous,median,ulnar,medial antebrachial and medial brachial cutaneous nerves)every 5 min up to 30 min after injection.Success of nerve block,side effects and complications were recorded during and after operalion.Results Group ICB was superior in success rate of anesthesia and nerve block of ulnar,medial antebrachial and medial brachial cutaneous nerves,the rate of parasthesia was lower and the block performance time was longer compared with group SCB(P ＜ 0.05).No major complications occurred in both groups.Conclusion Under ultrasound guidance,infraclavicular BPB is superior to supraclavicular approach.

Objective : To investigate the characteristics of HIV/AIDS cases at ages of 15 to 24 years reported in Ningbo City from 2011 to 2021, so as to provide insights into AIDS control among adolescents. Methods : The epidemiological data regarding HIV/AIDS cases in Ningbo City from 2011 to 2021 were captured from the AIDS Comprehensive Prevention and Control Information System of Chinese Disease Prevention and Control Information System, and the temporal distribution, population distribution, and routes of infections and detection were descriptively analyzed. Results : A total of 1 218 HIV/AIDS cases at ages of 15 to 24 years were reported in Ningbo City from 2011 to 2021, accounting for 17.41% of totally reported cases, and the proportion of HIV/AIDS cases in total HIV/AIDS cases during the same year appeared a tendency towards a decline from 2011 to 2021 (χ2trend=17.170, P<0.001). There were 993 males (81.53%) and 225 females (18.47%), 123 students (10.10%) and 1 095 off-campus adolescents (89.90%), and 904 with non-local registered residence (74.22%). Sexual behavior was identified as the predominant route of HIV infections (97.45%), including 714 men who had sex with men (58.62%). There were 636 cases with passive testing (52.22%), 305 cases with active testing (25.04%) and 219 cases with diagnosis at sexually transmitted diseases clinics (17.98%). Conclusions Men, non-local registered residence and off-campus adolescents were predominant among HIV/AIDS cases at ages of 15 to 24 years in Ningbo City from 2011 to 2021, with men-men sexual behaviors as the predominant route of HIV infections.

Objective:To explore the postoperative complications of different incisions of parotidectomy in benign parotid tumor and the impact on life quality.Methods:62 patients with benign parotid ttmor underwent improved parotidectomy in our hospital from January 2010 to January 2015 were selected and randomly divided into group A and group B.The patients in group A were using improved S incision,and the patients in group B were using postauricular concealing incision.Then the perioperative indexes,complications after surgery and the influences to life quality of 2 groups were observed and compared.Results:The surgery time,blood loss,postoperative suction drainage and hospital stays of 2 groups had no great differences (P＞0.05).The early and forward complication rate of group A was 29.03 ％ and 25.81％ respectively,of group B was 19.35 ％ and 12.90 ％ respectively.There were no differences between them (P＞0.05).The scores of pain and emotion after surgery of group A were getting better,and appearance,smell and chewing function was getting worse than before surgery with statistically significance (P＜0.05).The scores of pain and emotion after surgery of group B were getting better than before (P＜0.05).The scores of appearance and emotion of group A were worse than those of group B with statistically significance (P＜0.05).Conclusions:Using postauricular concealing incision can obtain good life quality and safety for the patients with benign parotid tumor,which is superior to improved S incision,worthy of clinical applications.

Objective By observing the changes in NGF and its receptor P75 in liver of CCl4-induced toxic rats and to evaluate the role of NGF in the mechanism of hepatic fibrosis.Methods The expressions of NGF mRNA and its receptor P75 were detecteded by both hemi-quantitative RT-PCR and Western blot analysis.Results The expressions of NGF mRNA and its receptor P75 in liver of CCl4-induced toxic rats at 24th hour group were higher than that in control group(P

Objective To study the correlation of multi-slice CT portography (MSCTP) and digestive endoscopy in the diagnosis and evaluation of esophageal and gastric varices (EGV) caused by cirrhosis.Methods A total of 92 patients with cirrhosis were enrolled in the prospective study.All the patients were examined by endoscopy and 64-slice spiral CT scan in 4 weeks.The types,grading of EGV were observed by endoscopy and MSCTP,and Kappa conformance test was applied with the endoscopic findings as gold standard.The sensitivity,specificity,consistency,and Youden index were evaluated for the diagnosis of sophageal and gastric varices by MSCTP.Results Sixty-five patients were diagnosed to have EGV by endoscopy and 27 were negative.The positive patients included 45 patients of GOV1,19 of GOV2 and 1 patient of IGV1.MSCTP diagnosed 67 cases of EGV and 25 patients of negative results.The positive patients included 46 of GOV1,18 of GOV2 and 3 of IGV1.Two patients of IGV1 varicose veins without positive findings on endoscopy were diagnosed by using MDCTP,which revealed isolated varicose veins under the gastric mucosa.There was high consistency between MSCTP and EGV in the diagnosis of EGV (Kappa =0.732,P ＜ 0.01).The sensitivity of MSCTP was 93.8％,specificity was 77.8％,consistency was 89.1％,and Youden index 71.6％.There was high consistency between MSCTP and EGV in the classification of EGV (Kappa values were 0.743 and 0.763,P ＜ 0.01).Conclusions There is high consistency between MSCTP and digestive endoscopic in the diagnosis and classification of EGV in cirrhosis.MSCTP is superior to endoscopy in the detection of gastric varices.

Objective:To study whether sacral lymph nodes should be included in the target volume delineation for those patients with early (stageⅠB-ⅡA) uterus cervix cancer during postoperative radiotherapy. Methods:Forty-six patients with early uterus cervix cancer were given postoperative three dimensional conformal radiation therapy (3D-CRT) in our department for one month after radical resection. The patients were randomly divided into two groups. The sacral lymph nodes were not included in the target volume delineation in the treatment group. But they were delineated in control group. All the patents had no radiotherapy-related contraindications and signed the consent agreement. The patients were followed up. The local controlling rate and the incidence and degree of radioactive proctitis were compared between the two groups. Results:The local controlling rate of the two groups had no significant difference(t=0.000, P=1.000). The doses received by the 5% and 95% volume of the rectum(V_5, V_95), the average dose, and the minimum dose had significant difference between the two groups(t_(V5)=2.169, P_(V5)=0.041; t_(V95)=4.036, P_(V95)=0.001;t_(mean)=2.236, P_(mean)=0.036; t_(min)=2.265, P_(min=0.034), but the maximum dose received by the rectum had no obvious difference (t_(max)=0.518, P_(max)=0.610). The incidence of radioactive proctitis had significant difference between the two groups(t=2.174, P=0.190). Conclusion:For the early uterus cervix cancer patients who have recurrent risk after radical surgery, sacral lymph nodes should not be included in the delineation of target volume during 3D-CRT in order to decrease the incidence of radioactive proctitis.
