OBJECTIVE:To explore the effect of dexmedetomidine with different doses combined with ropivacaine on the bra-chial plexus block. METHODS:Totally 90 patients with upper extremity surgery of brachial plexus block were randomly divided in-to test group,control group 1 and control group 2. Test group was treated with 0.375%ropivacaine 40 ml+dexmedetomidine 100μg, brachial plexus injection;control group 1 was treated with 0.375% ropivacaine 40 ml+dexmedetomidine 50 μg,brachial plexus in-jection;and control group 2 was treated with 0.375% ropivacaine 40 ml,brachial plexus injection. Onset time of sensory and motor nerve block,block duration,postoperative pain time for the first time and pain score,analgesia duration,quality of analgesia and muscle relaxant,before anesthesia induction(T0),plasma cortisol concentrations in nerve block 10 min (T1),the start of surgery (T2)and incidence of adverse reactions were observed. RESULTS:The onset time of sensory and motor nerve block and postopera-tive pain score for the first time in test group werecontrol group 1>control group 2,plasma cortisol concentrations at T1 and T2 were higher than T0,and T2>T1>T0,test group0.05). CONCLUSIONS:Ropivacaine combined with 100 μg dexmedetomidine can effectively im-prove brachial plexus block and shorten the onset time of sensory and motor nerve block,with good safety.

ObjectiveTo study the clinical significance of splenectomy in cirrhotic patients undergoing hepatic resection for PLC.Methods26 PLC patients with portal hypertension and hypersplenism were randomly divided into two groups: incidental splenectomy group ( n =11), and hepatectomy only group ( n =15). Postoperative blood picture and liver function was compared.ResultsThe WBC and PLT count significantly elevated after splenctomy, (8 9?1 6)?10 9 /L, (310?32)?10 9 /L; vs. (3 7?1 4)?10 9 /L and (104?41)?10 9 /L respectively (all P

Objective To study T lymphocyte subsets immunological condition of spleen in primary hepatocellular carcinoma (PHC) with liver cirrhosis. Methods T lymphocyte subsets such as CD4,CD8,CD4/CD8 in peripheral and spleen venous blood in 31 cases of PHC with liver cirrhosis were detected by FCM.and 13 patients with liver cirrhosis were observed as the control group. Results In 6 patients with stage Ⅰ liver cancer, CD8 of peripheral venous blood significantly decreased (P

ObjectiveTo study the changes of immune function after hepatectomy for hepatocellular carcinoma(HCC) in patients with liver cirrhosis.MethodsPatients with liver cirrhosis were used as control group,CD4?CD8?CD4/CD8? and protein expression level of IFN ??IL2?IL10 in peripheral blood from 18 advanced HCC cases with liver cirrhosis before and after heaptectomy were detected by flow cytometry(FCM) and ELISA.Results Postoperative CD4(33?3)%?CD4/CD8(1 1?0 1)?IL2(71?11)?pg/ml?IFN ?(90?15)?pg/ml level elevated compared to that of pre operation 〔CD4(29?4)%?CD4/CD8(0 9?0 3)?IL2(57?15)?pg/ml?IFN ?(78?13)?pg/ml〕(all P

Objective To establish the capability level classification system and capability level staffing standard of ICUs in tertiary hospitals, in an effort to raise the efficiency of nursing resources while ensuring quality of care of patients. Methods Such methods as experts meetings and Delphi Method were called into play to establish the nurses capability level system in ICUs with the convenient sampling method, we made clinical observation and research in 5 ICUs of 3 tertiary hospitals in Shanghai. Results Nurses in ICUs were classified into four levels, so were their responsibilities and job description. This way the system of nursing staff capability levels takes shape, and the staffing standards for nurses in ICUs of tertiary hospitals come into being. Conclusion Such tiered staffing standards in tertiary hospitals enable clinical nursing managers to deploy and efficiently use nursing staff of all levels.

Objective To study the methods and effects of endoscope-assisted partial thyroidectomy through subclavicular approach between the cervical anterior muscles and the sternocleidomastoid muscle.Methods The study included 15 patients with unilateral thyroid benign nodules.A transversal subclavicular incision 2~3 cm in length was made.Endoscope-assisted partial thyroidectomy was performed through the subclavicular approach between the cervical anterior muscles and the sternocleidomastoid muscle.Results The operation was accomplished successfully in all the 15 patients.The operation time was 40~80 min(mean,50 min) and the intraoperative blood loss was 10~50 ml(mean,20 ml).No surgical complications occurred.The patients were discharged from hospital on 3~4 postoperative days.Follow-up observations in the 15 patients for 1~12 months(mean,7 months) revealed no recurrence.Conclusions Endoscope-assisted partial thyroidectomy through subclavicular approach between the cervical anterior muscles and the sternocleidomastoid muscle has the advantages of minimal invasion,little blood loss, low complication rate,quick recovery,and good cosmetic results.

Objective To study the relationship between the low level lead exposure of pregnant woman and the gestational age of fetus. Methods The peripheral blood and the umbilical blood samples were collected from 1 000 healthy puerperants and their newborns. The puerperants were divided into three groups according to the blood lead levels: very low-level group(0.483 ?mol/L). Results The rate of premature labor was 9.40% in the very low-level group, 14.07% in the low-level group and 23.81% in the high-level group respectively. The blood lead level of puerperants had a positive correlation with the umbilical blood lead of newborns. The umbilical blood lead of premature was higher than that of mature. As the blood lead level of the pregnants increased, the gestational age shortened and the probability of low age premature increased. Conclusion As for the toxicity of lead to the fetus, there is no a threshold. Low level lead exposure of the pregnant woman is one of the causes of premature labor.

Objective:To study the short-term effects,toxic side effects and immune function of Aidi injection adjuvant GP methods chemotherapy for advanced non-small cell lung cancer(NSCLC).Methods:130 patients with advanced NSCLC were divided into study group and the control group according to treatment methods.The study group were given Aidi injection +GP,and the control group only treated with GP.The short-term effects,toxic side effects gradeⅢ-Ⅳand immune function changes were compared between the two groups.Results:The overall response rate was 40.28%in study group,higher than 37.93% in control group(P>0.05).The two groups showed differences in the rates of leucocyte decrease,gastrointestinal reaction and platelets decrease(P<0.05).The levels of CD4,CD8 and CD4/CD8 didn′t changed obviously in study group(P>0.05),while in the control group the levels of CD4,CD8 and CD4/CD8 changed more significantly than before(P<0.05).The two groups also produced differences in CD4,CD8 and CD4/CD8 after treatment( P<0.05 ) .Conclusion: The short-term effects of Aidi injection adjuvant GP chemotherapy regimen for advanced NSCLC is similar to only GP chemotherapy,but it can obviously reduce the incidence of toxic side effects and prevent the immune func-tion.

Objective To investigate the pathological features of gastro-esophageal high-grade intraepithelial neoplasia (HGIEN) confirmed by biopsy and to compare the differences of its diagnosis after endoscopic resection. Methods Data of 147 patients with gastro-esophageal HGIEN confirmed by biopsy, who underwent EMR or ESD in recent 4 years were analyzed for the pathological findings of pre- and post- procedures. Results Among 147 cases of HGIEN diagnosed by endoscopic biopsy, 106 lesions were in esophagus and 41 in stomach. After endoscopic resection, intraepithelial neoplasia was confirmed in 97 (66%), and cancer was diagnosed in 50 (34%), of which submucosal layer was involved in 11. There were 34 cases of adenocarcinoma and 16 squamous cell carcinomas, in which 22 cases (44%) were poorly or moderately differentiated. Conclusion More than one third cases of biopsy diagnosed HGIEN are confirmed to be carcinoma after endoscopic resection, which needs active therapeutic measures.
