Objective To determine the effectiveness and clinical result of intraoperative monitoring of compound muscle action potential (CMAP) in avoiding nerve root impingement during lumbar spine intrapedical instrumentation. Methods Twenty-five cases were given intraoperative stimulus-evoked electromyographic monitoring. After anode of stimulating electrode was placed at the Kirschner wire inside the passage of pedicle screws, the integrity of the pedicle cortex was tested by stimulating each screw head and recording compound action potentials of relevant muscles. Results Stimulation at an intensity of 16.2 mA evoked a compound muscle action potential in one case and that at over 35 mA did in four cases. No neurologic deficits were found in any case intraoperatively or postoperatively. Conclusions Stimulating intensity below 10 mA needs rearranging screw site. A stimulation intensity of 10-20 mA indicates X-ray inspection and visual inspection to exclude any pedicle breaches. Stimulation thresholds above 20 mA can be regarded as safe threshold to monitor the nerve root impingement. Intraoperative electromyographic monitoring provides a real-time watch-dog for monitoring spinal nerve root injury during posterior lumbar instrumentation.

[Objective]To investigate the value of intra-operative somatosensory-evoked potential monitoring in surgery for thoracic spinal stenosis.[Method]Twenty-two patients with thoracic spinal stenosis underwent decompressive laminectomy surgery.The preoperative and intraoperative SPEs were recorded.The SEPs were analyzed with three indices:(1)SEPs wave pattern;(2)P40 latency;(3)P40-N50 amplitude.More than 50% decrease in SEPs amplitudes or more than 10% increase in latency was considered to be the warning threshold.[Result]Cases were classified into four groups according to preoperative SPEs wave pattern.Type Ⅰ inclued 2 cases whose SEPs monitoring had least meaning,and the spinal cord function remained unchanged postoperatively.4 cases with Type Ⅱ and the SEPs wave pattern were too unreliable to make analysis.Eleven cases in Type Ⅲ showed significant changes on SEPs,and most patients felt relief of symptom a week later.Type IV with 5 cases showed normal SEPs and all of them got well restored neurological function.[Conclusion]SEPs has good correlation with clinical outcomes.Its sensitivity,instant response and quantitative analysis make SEPs with great effectiveness in intraoperative monitoring on surgery of thoracic spinal stenosis.

For both Yin - and yang juandice observations were made on liver functions, bilirubin, RBC hematocrit, T lymphocyte subgroup, cholic acid, hyaluronie acid, laninated mucin. It was found that, for both group. there were, not only difference in signs and symptoms but also differences in laboratory indices. It was primarily supposed that, for yin - juandice. there are decrease of bilirubin catabolism by hepatic cells. Further, the source of bilirubin is increased, abnormal hepatic microcirculation, liver fibrosis and hypofunction of metabolism, the pathological characteristics of yin juandice being weekness in both body resistance, and the pathogens, with stagnation of bile and stasis of the blood.

Objective To explore the neuroprotective effects of Buchang Naoxintong Capsule on focal cerebral ischemia/reperfusion in rats.Methods Rat model of ischemic reperfusion of cerebral middle artery was established according to Zea Longa's pattern. Rats were randomly divided into pseudo-operation group, ischemia/reperfusion group and Buchang Naoxintong Capsule treated group. The ischemia/reperfusion group and Buchang Naoxintong Capsule treated group were both divided into five subgroups according to reperfusion time or administration time such as 1 d, 3 d, 7 d, 10 d and 15 d. Using immunohistochemical staining method and color image analysis, we measured the expression of vessel endothelium growth factor (VEGF) and Laminin in the region of ischemia. Pathological changes were observed with HE staining and transmission electron microscope. Besides that, the content of brain water was assayed.Results Compared with ischemia/reperfusion group, less numbers of shrinkage or swelling neurons were found in Buchang Naoxintong Capsule treated group.The content of brain water, the expression of VEGF were obviously different between Buchang Naoxintong Capsule treated group and the other two groups (all P

OBJECTIVE:To observe the curative efficacy of compound glycyrrhizin in the treatment of chronic type B hepatitis.METHODS:102patients with type B hepatitis were randomly selected to receive compound glycyrrhizin60ml by in-travenous drip infusion once daily for30days.The clinical symptoms,signs,and indexes of hepatic function and hepatic fibrosis were observed before and after treatment.RESULTS:As compared with treatment before,patients’symptoms,signs,indexes of hepatic function and hepatic fibrosis all had obvious amelioration after treatment(P

Objective To measure the equity of resources allocation in obstetric healthcare in Zhejiang Province, and provide evidence for decision making by healthcare departments of the government. Methods Lorenz curve and Gini coefficient were used to measure the equity of obstetric healthcare resources. Results The investigation found such allocation as equitable as measured by the layout of the number of live births, as the Gini coefficient of the distribution of obstetric doctors, nurses and beds was 0.1697,0.1971 and 0.1497 respectively by total birth, failing within the equitable range. However, when measured by geographic distribution, such coefficient were 0.2701, 0.3216 and 0.3341 respectively in cities, which were less equitable yet still within equitable range. Conclusions The government and health bureaus are recommended to scientifically predict the number of immigrants and rationally deploy healthcare resources according to the service radius of healthcare resources;moreover, more gynecologic doctors and nurses should be trained to improve the human resource structure in gynecologic departments. These effort can cater to the growing healthcare demands of the society resulting from a growing population of immigrants.

ObjectiveTo observe the efficacy of L-carnitine in prevention and treatment of toxicity of LFP chemotherapy with gastrointestinal cancer. Methods60 cases of gastrointestinal cancer were divided into 2 groups according to the admission date. The treatment groups received LFP chemotherapy and L-carnitine, while the control group received LFP chemotherapy alone.Both groups received 3 cycles chemotherapy. The gastrointestinal toxicity, neurotoxicity, hematologic toxicity and physical state were compared.ResultsThere were 12 cases of peripheral neurotoxicity in treatment group,the incidence rate was 40.0 ％;but in control group there were 21 patients, and the incidence rate was 70.0 ％. There was a significant difference between the two groups(x2=5.4545,P =0.0195). Anemia in the treatment group was 56.7 ％ (17/30); in the control group the rate was 86.7 ％ (26/30).There was a significant difference between the two groups (x2 =6.698,P =0.0351).After chemotherapy,in the treatment group,there were 4 cases with increasing Karnofsky score ≥ 10,19 patients whose Karnofsky score did not change,and 7 cases with reduced Karnofsky score ≥ 10; in the control group,there was 1 case with increasing Karnofsky score ≥ 10,13 cases with Karnofsky score no changing,and 16 cases with reduced Karnofsky score ≥ 10.The changes in physical state of two groups had a significant difference(x2 =5.711,P =0.0169).The gastrointestinal toxicity,thrombocytopenia,and neutropenia of two groups had no significant difference.ConclusionL-carnitine can reduce peripheral neurotoxicity and hematologic toxicity,improve the patient's physical state in patients received LFP chemotherapy.

Objective To explore the correlation of mycoplasma pneumoniae infection with frequent relapses of steroid-sensitive nephrotic syndrome (SSNS) in children.Methods 35 patients with relapse of SSNS and acute respiratory tract infection were divided into a observation group (mycoplasma pneumoniae infection) and a control group.The clinical and laboratory data including 24 h urine protein (24 h-Upro),urea nitrogen (Bun),serum creatinine (Scr),albumin (Alb) and cholesterol (Chol) were analyzed before and after treatment.Results The clinical and laboratory indexes were obviously improved after treatment,the difference was statistically significant (P ≤ 0.01).24 h-Upro decreased more significantly in the observation group than in the control group after treatment.In the observation group,15 of 18 children achieved the efficacy,9 of whom had complete response and 6 had partial response.In the control group,14 patients achieved the efficacy,6 of whom had complete response and 8 had partial response.Conclusions After treatment,most of the children with frequent relapses of steroid-sensitive nephrotic syndrome induced by cute respiratory infection are relieved.Proteinuria,hypoproteinemia,hyperlipidemia,and renal function were improved in those patients.Therapies with azithromycin achieves a more marked efficacy.

Tetraspanins are a class of cell surface glycoproteins that are expressed very broadly, which can form a complex tetraspanins net by combining with many kinds of cell surface molecules such as integrins, signal proteins, growth factors and so on.In recent years, more and more studies suggest that tetraspanins are closely related to the invasion and metastasis of malignancies and show a certain clinical value, which can be used as new diagnosis and prognosis indicators of malignancy.
