Objective T_O analyze the electrophysiological features of shoulder-hand syndrome(SHS)fol- lowing stroke and investigate the relationships between peripheral nerve damage and the factors causing SHS.Meth- ods Fifty-eight stroke patients were divided into an SHS group(39 patients with shoulder-hand syndrome)and a model group(19 patients without shoulder-hand syndrome).Standard sensory and motor nerve conduction studies were performed with 58 of the patients,including sensory nerve conduction velocity(SCV),amplitude of the sensory nerve action potential(SNAP),distal motor latency(DMI)and the amplitude of the compound muscle action poten- tial(CMAP)of the median nerve.A needle electromyogram(EMG)test was performed on the abductor pollicis of the affected side with both groups.Results The needle EMG showed abnormal insertion potential,fibrillation po- tential and positive sharp waves in all 39 cases of the SHS group,which was significantly higher than in the model group.The amplitude of the sensory nerve action potential(7.77?4.34 mV)and the amplitude of the compound muscle action potential(10.13?3.15 mV)were significantly lower than those of the model group.Abnormal ampli- tude was more severe in sensory nerves than in motor nerves.Conclusion Peripheral nerve damage was found in the shoulder-hand syndrome patients,and this damage was mainly the dystrophy of axonal neuropathy.The damage severity was more in sensory nerves than in motor nerves.The study could offer an useful clue of prevention and treat- ment of shoulder-hand syndrome.

Objective In order to reveal the effect of extracorporeal shock wave therapy (ESWT) with ultrasonic orientation for soft tissue disorders of the shoulder. Methods 151 cases of severe disorders of the shoulder were treated with ESWT. The course of disorders was longer than 3 months. Among them, 65 cases were of subacromial bursitis (SB) and 86 of tenosynovitis of long-tendon of biceps muscle (ILBM). The treatment point of ESWT was oriented with color Doppler ultrasonography, while the pain-point was determined with tenderness combining with local anatomic markers. The energy density of ESWT was 0.12-0.16 mJ/mm2, and 1-2 shock-points were selected for each treatment, the number of shock waves were 800-1000 times, each course consisted of 2-5 times, with an interval of 5 days. 25 of 65 cases of SB were refered for ESWT by ultrasonic orientation, other 40 by pain-point orientation; 31 of 86 cases of ILBM were refered for ESWT of ultrasonic orientation, other 55 by pain-point orientation. The satisfactory rate of SB and ILBM with ESWT were compared between 2 different orientation cases. Results Through 6 months follow up, the satisfactory rates of SB and ILBM with ESWT were 89.6% and 92.3% respectively in cases of ultrasonic orientation, while in cases of pain-point orientation, the satisfactory rates of SB and ILBM with ESWT were 67.6% and 73.6% respectively, the difference of satisfactory rates was significant between 2 groups. Conclusion The effect of the ESWT with ultrasonic orientation is better than the ESWT with pain-point orientation both for SB and ILBM. The ultrasonic orientation plays an important role in promoting the satisfactory rates of ESWT.

Objective To investigate the clinical characteristics of septicemia in type 2 diabetes mellitus,to enhance prevention level and decrease death rate.Methods A retrospective study was carried out,the data were collected from 58 cases of type 2 diabetes mellitus complicated by septicemia in our hospital in the past 13 years.Results The pathogenic invasive pathways included:19 cases of urinary tract,17 cases of respiratory tract,7 cases of intravenous catheter detain,7 cases of biliary tract,1 case of skin breakage,and 7 cases of unclear origin.Twenty-three of 58 cases were from nosoeomial infection (39.7%),among which 10 cases of urethral detain,7 cases of intravenous catheter detain,and 6 cases of respiratory tract infection.Pathogenic distribution was as following:24 cases of klehsiella pneumoniae,16 cases of escherichia coli,10 cases of staph aureus,2 cases of staphylococcus cohnii cohnii,2 cases of staphylococcus epidermidis,2 cases of pseudomonas putida,2 cases of candida glabrata.Among the 24 cases of llehsiella pneumoniae,12 cases showed migrating hepatapostema (50.0%),and 15 showed pneumatosis phenomenon in the intrahepatie bile (62.5%).Two cases originated from fungal septicemia.Among 56 cases under antibacterial therapy 15 cases developed fungal septicemia (26.8%).Fifty-eight cases were treated with insulin for forcing down serum glucose,56 cases of bacterial septicemia were treated with the third generation cephalosporins and fluoroquinolones.Two cases of pseudomonas putida septicemia were treated with intravenous injection of fluconazole.Seven cases died (12.1%).Conclusions Gram-negative bacilli were the major pathogens of septicemia in type 2 diabetes mellitus.Migrating hepatapostema and pneumatosis phenomenon in the intrahepatic bile often showed klebsiella pneumoniae septicemia.The important risk factors for septicemia were intravenous catheter detain and urethral detain.Therefore,strictly aseptic operation and removing vessel detain in time is very important.It is key points to make an early diagnosis,have a strong antibiosis therapy and treat the migrating pathogenic focus.And it is important to intensify serum glucose monitoring and strengthen supportive treatment.

Objective To study the influence of hydrogen sulfide (H2 S)on the mitochondrial function of pulmonary artery smooth muscle cells of the rats with high pulmonary blood flow pulmonary hypertension, and to clarify the function and its mechanism in the occurrence of high pulmonary blood flow pulmonary hypertension.Methods A total of 27 rats were randomly divided sham operation group,operation group,and operation+sodium hydrosulfide (NaHS)group (n=9).The pulmonary hypertension rat model was built by left lung resection.After fed for 35 d, the mean pulmonary artery pressure (mPAP),ratio of right ventricle/body weight (RV/BW),and ratio of right ventricle/(left ventricle+septum)[RV/(LV + S)]of the rats in three groups were measured.The plasma H2 S levels and the CSE activities in pulmonary artery tissue of the rats were detected;the activities of total mitochondrial ATP enzyme,superoxide dismutase (SOD),glutathione peroxidase (GSH-Px)and malondialdehyde (MDA)levels were determined;the ultrastructure of pulmonary artery smooth muscle mitochondria was observed through transmission electron microscope.Results Compared with sham operation group,the plasma H2 S level and the CSE activity in pulmonary artery tissue of the rats in operation group were decreased(P<0.01);the mitochondrial membrane of pulmonary tissue was swelling, and the mitochondrial activity was decreased (P<0.01);the mitochondrial ATP enzyme,SOD and GSH-Px activities were significantly decreased,and the MDA level was significantly increased (P<0.01).Compared with operation group,the H2S level in plasma and the activity of CSE in pulmonary tissue of the rats in operation + NaHS group were increased (P<0.01 );the mitochondrial membrane swelling was reduced, and the vitality was restored;the ATP enzyme, GSH-Px, and SOD level in pulmonary tissue were significantly increased (P<0.01),and the MDA level was significantly reduced (P<0.01).Conclusion H2 S can enhance the activities of mitochondrial ATP enzyme,GSH-Px,and SOD,and decrease the mitochondrial lipid peroxidation level,thus it plays a protective effect on rat pulmonary artery smooth muscle.

Objective To investigate the anti-apoptosis effects of heme oxygenase-1 (HO-1) in a mouse model of liver ischemia-reperfusion ( IR ) injury and to analyze the possible mechanisms . Methods A cell model of hypoxia/reoxygenation injury was established after transfecting mouse liver AML12 cells with HO-1 small interfering RNA ( siRNA) . Real-time PCR and Western blot assay were performed to detect the changes of HO-1, B-cell lymphoma 2 (Bcl2) and caspase-3 at the cellular level. The mouse models of liver ischemia-reperfusion injury were established with/without pretreatments with cobalt proporphyrin (CoPP), CoPP+znic proporphyrin ( ZnPP) and/or ZnPP. The levels of aspartate transaminase ( AST) and alanine transaminase ( ALT) in serum samples were measured. Immunohistochemistry was used to analyze the chan-ges of caspase-3. Western blot assay was used to detect the expression of HO-1 and Bcl2 at protein level. The pathological changes of liver tissues were observed under light microscope. The apoptosis of hepatocytes was observed by using Tunel assay. Results Decreased expression of HO-1 and Bcl2 and increased expres-sion of caspase-3 were observed in the model of hypoxia/reoxygenation injury by pre-transfecting the AML12 cells with HO-1 siRNA. Compared with the IR injury group, the CoPP pretreatment group showed lower lev-els of AST and ALT (P<0. 05) and alleviated pathological damages in liver tissues. Moreover, the expres-sion of caspase-3 was inhibited, but the expression of HO-1 and Bcl2 were enhanced. Less apoptotic cells was detected by the Tunel assay (P<0. 05). However, these protective effects could be suppressed by adding ZnPP. Conclusion HO-1 has anti-apoptotic effects in the in vitro model of hypoxia/reoxygenation. CoPP can upregulate the expression of HO-1 and play the role of anti-apoptosis in a mouse model of liver is-chemia-reperfusion injury.
