Objective To explore clinical and pathological characteristics of neurological lesions in primary Sj(o)gren's syndrome (pSS).Methods Ten patients diagnosed as pSS with nervous system involvement were analyzed retrospectively with autoimmune antibody test,cerebrespinal fluid examination and Schivmer's test,six pSS patients with peripheral nervous system lesions (PNS-pSS) were examined with electromyography and nerve conduction velocity and four pSS patients with central nervous system lesions (CNS-pSS) were examined with cranial MRI to analyze their clinical and pathological characteristics.Salivary gland biopsy was performed for all the ten patients,sural nerve biopsy for those with PNS-pSS and brain biopsy or spinal autopsy for those with CNS-pSS.Results Clinically,six patients with PNS-pSS presented symmetrical sensory-motor peripheral neuropathy or pure sensory peripheral neuropathy and four patients with CNS-pSS presented multiple sclerosis,subacute transverse myelitis,encephalitis,pituitary stroke and acute meningitis with varied lesions in the myelin sheath and axon by electromyography and motor nerve conduction velocity.Cranial MRI showed lesions in the white matter of the brain,spinal cord and abnormal signals in the pituitary.Pathologically,sural nerve biopsy showed typical vasculitis and nonvasculitis characterized as degeneration of the axon and myelin sheath,salivary acinar gland biopsy showed its atrophy and infiltration with lymphocytes,and brain biopsy showed demyelination of the brain and spinal white matter,as well as infiltration of lymphocytes surrounding the veins,typical vasculitis and bleeding and necrosis of the pituitary.Conclusions Both central and peripheral nervous systems can be involved in pSS,with complicated clinical manifestations.Electrophysiology,cerebrospinal fluid tests and histopathological examinations by biopsy are essential in diagnosis for neurological lesions in patients with pSS.Inflammatory reaction of the blood vessels and tissues mediated by cell immunity may be involved in mechanism of its neurological lesions.

Objective To value the effect and safety of butyl phthalide sequential treatment in cerebral infarction of branch sclerosis of arterial congee appearance. Methods Sixty patients with acute cerebral infarction were randomly divided into treated group( n = 31)and control group( n = 29). According to the condition of illness,all patients were given aspirin,atorvastatin calcium,and the injection of ozagrel sodium intravenous;controlled the blood pressure,blood sugar,blood lipid,and treated complications posstively;take the early rehabilitation of nerve treatment afte the illness was in stable condition. Butyl phthalide was used in the patients of treated group(100 ml,twice per day,intravenous drip,during 14 days period therapy,and then 0. 2 g oral,third per day),besides the routine therapy. The degree of neural function defect score( NIHSS)and activities of daily living score(BI)between two groups were observed before and after treatment. Corresponding adverse consequences were recorded. Results Compared with pretreatment,the NIHSS of postreatment at the 14th day in treat and control groups were decreased(treated group:(4. 36 ± 3. 11)vs.(11. 42 ± 3. 20);control group:(6. 12 ± 2. 67)vs.(11. 64 ± 3. 43),P < 0. 05,and the treated group was significantly lower than control group(F inner groups = 2. 125,P < 0. 01;F between groups = 18. 63,P < 0. 01;F cross groups = 25. 34,P< 0. 01;P < 0. 05). The BI of postreatment in two group were increased(treated group:(86. 72 ± 8. 44)vs. (26. 54 ± 13. 36);control group:(75. 96 ± 9. 86)vs.(26. 38 ± 13. 02)),and the treated group was significantly lower than control group(F inner groups = 29. 27,P < 0. 01;F between groups = 32. 48,P < 0. 01;F cross groups= 42. 41,P < 0. 01;P < 0. 05). There was no the adverse reactions. Conclusion Butyl phthalide sequential treatment can improve the NIHSS and BI of cerebral infarction of branch sclerosis of arterial congee appearance and have a better therapy effect.

Objective To observe the therapeutic effects and assess the feasibility of radiofrequency thermo- coagulation denervation(TRD)mediated by digital subtraction angiography(DSA)for patients with lumbar facet joint syndrome(LFJS).Methods Eighty LFJS patients were randomly divided into two groups:a denervated group(groupⅠ)and a control group (groupⅡ).The lumbar facet joints of the patients in groupⅠwere treated with TRD,while those in groupⅡhad their lumbar facet joint cavities injected with the mixture of 1 mg betamethasone and 1 ml lidocaine.All patients were assessed using the Visual Analog Scale(VAS)before treatment and 30 rain,1 d, 1 w,1 m and 6 m after.Schober values were measured at 1 w,1 m and 6 m after treatment.The therapeutic effects and side effects were assessed at 6 m after treatment.Results VAS scores in groupsⅠandⅡat 30 min,1 d,1 w and 1 m after treatment were remarkably lower than before treatment.In addition,those in groupⅠ6m after treatment were also significantly lower(P＜0.01).Compared with those in the groupⅡ,VAS scores in groupⅠwere signifi- cantly decreased at 1 m and 6 m after treatment(P＜0.05 and P＜0.01,respectively).The schober values in groupⅠat 1 m and 6m were obviously increased in comparison with those in groupⅡ,while the therapeutic effects in groupⅠat 6m after treatment were better than those in groupⅡ(P＜0.01).There were no side effects,such as injuries to the nerve roots or dysfunctional dermal sensation,in either group.Conclusion TRD,mediated by DSA,has ther- apeutic effects on LFJS.Such treatment is safe,convenient,and gives long-term pain relief.

[ Objective] To observe the therapeutic effect of fetus - soothing and liver - clearing therapy for pregnancy associated with chronic hepatitis B. [Methods] Fifty cases of pregnancy associated with chronic hepatitis B were treated with fetus - soothing and liver - clearing Decoction, which is mainly composed of Semen Cuscutae, Radix Astragali, Radix Scutellariae, Herba Phyllanthus and Herba Taraxaci. After treatment, general state of gravida, indexes of hepatic function, hepatitis B virus (HBV) marker and hepatic fibrosis were detected. [Results] No miscarriage was found in the cases. Serum levels of glutamic - pyruvic transaminase, bilirubin and hyaluronic acid ( HA) were decreased obviously , the difference being significant as compared with those before treatment ( P

OBJECTIVETo investigate the short-term prognostic value of the indocyanine green clearance test when used in combination with the model for end-stage liver disease (MELD) scoring system to assess patients with hepatitis B virus acute-on-chronic liver failure (HBV-ACLF).

METHODSClinical data of 105 patients diagnosed with HBV-ACLF were retrospectively analyzed. The indocyanine green retention rate at 15 minutes (ICGR15), clinical data within 24 h after diagnosis, Child-Turcotte-Pugh (CTP) classification, MELD score, MELD combined with sodium concentration (MELD-Na) score, and King's Hospital (KCH) criteria data were collected for analysis. Measurement data were assessed by t-test and count data by the chi-square test. Short-term predictive accuracy for patients with HBV-ACLF was compared between different models using the area under the receiver operating characteristic (ROC) curve (AUC).

RESULTSThe mortality rate for all patients was 45.71%. Comparison of the survivors versus the non-survivors showed that age, total bilirubin, albumin, cholinesterase, creatinine, international normalized ratio, and incidence positive rate of relative complications (hepatorenal syndrome, hepatic encephalopathy) were significantly different between the two groups (all, P less than 0.05). The ICGR15 was found to be positively correlated with MELD score (r = 0.205, P less than 0.05). The MELD-ICGR15 model constructed by logistic regression analysis was: Logit(P) = 0.193 * MELD + 0.130 * ICGR15 - 11.256. The AUC was 0.880 and the cut-off was -0.706, with 89.6% sensitivity and 75.4% specificity. The AUC of the MELD-ICGR15 model was significantly higher than that of the ICGR15 (0.820), MELD score (0.779), MELD-Na score (0.761), KCH criteria (0.680), and CTP classification (0.631) (all, P less than 0.05).

CONCLUSIONICGR15, MELD score, and MELD-Na score had higher predictive values for HBV-ACLF than did CTP classification or KCH criteria. Furthermore, the MELD-ICGR15 model was better than any single parameter model for predicting the short-term prognosis of patients with HBV-ACLF.

Food and drug supervision is a specialized job. However, the present supervisors coming from various departments have differences in supervision concepts, professional background, knowledge structure and work experience, which shows large gap with the requirements of supervision work. Therefore, it is urgent to strengthen the classified training for the improvement of quality construction and specialization. The article provided the curriculum system, teaching explanation and ideas about the classified training for all supervisors in the whole system, which may be beneficial to the training of food and drug supervisors.

The 13th five-year plan pointed out clearly that it is necessary to implement food safety strategy , and form a manage-ment system for strict and efficient social co-governance of food safety .The paper introduced the practice and the results of food safety co-governance in Yunnan province , and provided some proposals with the purpose to help the development of food safety co -governance work in the other areas .

After the structural reform in the food and drug supervision system, the knowledge structure and the professional re-quirements of the supervisors is unmatched, which hinder the fulfillment of regulatory responsibilities and the performance of adminis-trative efficacy. Effective ways for team building are actively explored throughout the country. The paper introduced the adult corre-spondence education of the supervisors in Zhejiang Ningbo food and drug supervision system to provide a good example for training work throughout the country and some useful suggestions for the quality improvement of the supervision team.

OBJECTIVETo develop a draft questionnaire (China Musculoskeletal Questionnaire, CMQ) for evaluating of musculoskeletal workload and associated potential hazardous working conditions as well as musculoskeletal symptoms of workers in Sitting Posture.

METHODSMulti-methods, which include the reviewing references, the summarizing results of preliminary studies, the reviewing ergonomic tools, the consulting experts and occupational health workers and the interviewing or discussing with individual workers in sitting posture, were used in developing item pool. The experts and epidemiologists of occupational health scored the importance of every single item in the item pool, and then the survey and sampling were carried out in 325 workers of sitting posture who completed the questionnaire. On the basis of these data, the methods including experts scoring, item analysis, Cronbach's α analysis and factor analysis were synthetically used to select the reliable items which consisted of the formal questionnaire.

RESULTSThe standard of the CMQ, which consists of 34 items on musculoskeletal workload and associated potentially hazardous working conditions, can be divided into nine indices (dynamic loads, static loads, repetitive loads, forces-exertion, prolong time, climatic factors, vibration, position and ergonomic environmental factors).

CONCLUSIONThe CMQ possesses good content validity, and the items of CMQ are divergent, reliable and typical. However, the reliability and validity of CMQ should be validated.

This study was aimed to investigate the effect of 1,25(OH)(2) vitamin D(3) [1,25(OH)(2) Vit D(3)] on the differentiation, maturation and function of human dendritic cells (DC) in vitro and its mechanism. Human peripheral blood mononuclear cells were induced to differentiate to DC in vitro. The DC in test group were cultured with 1,25(OH)(2) Vit D(3) 1 nmol/L for 9 d, while the DC in control group were cultured with the equivalent of absolute alcohol. The expression of co-stimulatory molecules on DC were analyzed by flow cytometry. T cell proliferation induced by DC was assessed by MTT method. The expression of indoleamine 2, 3-dioxygenase (IDO) protein was determined by Western blot. The results showed that compared with the control group, the expression of CD80, CD83 and CD86 on DC in test group was significantly down-regulated (P < 0.05), while the CD1a was up-regulated (P < 0.05). The expression rate of CD80, CD83, CD86, CD1a in test group were (40.43 ± 9.83)%, (20.04 ± 4.73)%, (14.45 ± 5.38)%, (58.48 ± 10.72)% respectively, while in control group were (29.36 ± 13.34)%, (35.91 ± 10.19)%, (27.15 ± 11.64)%, (72.20 ± 12.79)% respectively. Compared with the control group, 1,25(OH)(2) Vit D(3)-treated DC exhibited a markedly reduced ability to stimulate allogenic T cell proliferation and up-regulated IDO protein expression.It is concluded that 1,25(OH)(2) Vit D(3) efficiently inhibits the maturation of DC and DC-mediated T cell proliferation, which may be related to the up-regulation of IDO protein expression.
