Objective To analyze the factors related to the fetal death and to find the effective interventions. Methods 84 women with fetal death were recruited.Clinical data were collected and analyzed based on the retro-spective method.Results Among the 84 women,21 women with pregnancy complications,2 women delivered fetal macrosomia,2 women with oligohydramnios,4 women with polyhydramnios,50 women with abnormal umbilical cord, 1 woman with fetal growth restriction,1 woman with racket -shaped placenta,2 women with unknown causes,and 1 woman with placental calcification.Conclusion The main cause of fetal death was pregnancy complications and umbilical cord abnormalities.The early diagnosis,promptly correct,and timely termination of pregnancy will be the effective interventions to prevent the development of the fetal death.

Objective To explore the change of the total level of lgE and specific allergen for acute exacerbation of bronchial asthma and to offer evidence for the prevention and cure of acute exacerbation of bronchial asthma.Methods The usual inhalant and ingested antigens were chosen in asthma patients,and the allergens were detected by ELISA in sera of acute exacerbation of bronchial asthma patients.Results Total positive rate of lgE was 92％ (48/52),dust mites 61.2％ (25/52),house dust 17％ (9/52),shrimp and crab 15％ (8/52),mould 9％ (5/52).Conclusion The main allergen of acute asthma exacerbation is dust mites.House dust,shrimp and crab,and mould folloo.The rats of pollen or weed are very low.

Objective To develop the quality of life questionnaire applicable to the Chinese patients with dysphagia by the translation and modification,as well as psychometric evaluation of the original swallowing quality of life questionnaire (SWAL-QOL).Methods The English version of the SWAL-QOL was translated into Chinese according to the well-accepted scale translation procedure.Then 103 patients with dysphagia were tested using the translated Chinese SWAL-QOL.The inter-rater reliability,test-retest reliability,internal consistency reliability,the content validity and construct validity were tested.Results The inter-rater reliability correlation coefficient of the SWAL-QOL was between 0.945-0.990 (P＜0.01).Its test-retest coefficients ranged from 0.965 to 0.992 (P＜0.01).The Cronbach coefficients ranged from 0.708 to 0.933 (P＜0.01).There revealed significant correlation between each item of SWAL-QOL and its domain,with correlation coefficients between 0.723 and 0.982 (P＜0.01).Factor analysis of each item of the 10 domains of SWAL-QOL extracted 10 common factors,which were with a cumulative contribution of 79.029％.Factor analysis of the total score of the 10 dimensions extracted 2 common factors including dysphagia-related quality of life and general quality of life,with a cumulative contribution of 54.718％.Conclusions The Chinese version of SWAL-QOL is reliable and valid.It can be used as an effective measuring tool to evaluate the quality of life of dysphagia patients.

Objective To observe the hemolysis,allergic reactions and stimulation of Polydatin Injection(PI),thus to provide evidence for clinical medication.Methods Hemolysis was observed by in-vitro rabbit blood hemolysis.Sys- temic allergy and passive skin allergy were tested on guinea pigs and rats.Vascular stimulation and muscle stimulation were tested on rabbits.Results There was no hemolysis or reaction in erythrocyte agglutination 30,60 and 180 rain after adding PI.No systemic anaphylaxis was found in guinea pigs.There was no skin allergy passive in rats.There was no vascular stimulation or muscle stimulation after injecting PI(0.39 mg/mL)5.6 mg/kg into rabbit ears.Con- clusion Under experimental conditions,PI(0.39 mg/mL)shows no hemolysis in vitro or agglutination reaction;it has no systemic anaphylaxis or passive skin allergy;it either has no stimulating effect in rabbit auricular vessels and muscles.

Objective To investigate the therapeutic effect of CTLA4Ig gene on experimental autoimmune thyroiditis (EAT) by the use of portable synthetic costimulatory molecules of cytotoxic T lymphocyte antigen 4 (CTLA-4) antagonist (CTLA4Ig) eukaryotic expression vector.Methods Thirty C57BL/6J female mice were divided into three groups,named EAT model group (EAT,n =10),CTLA4Ig-treatment group (CTLA4Ig-EAT,n =10) and control group(n =10).At 28 day after first immunization,plasmids mixture with pCI or pCI/CTLA4Ig were injected into thyroid tissues of EAT and CTLA4Ig-EAT by surgery,respectively.Serum,thyroid tissues and spleens were collected as samples.Thyroid autoantibody and expression of interleukin (Th)1,Th2 related cytokinesby were measured by real-time quantitative PCR and ELISA.Results Compared with EAT group,the expression of CTLA-4 in thyroid of CTLA4Ig-EAT group was elevated double folds (P =0.038),and the expression of Th1 cytokine interferon γ and intercellular adhesion molecule-1 decreased significantly (P =0.016,0.042).Meanwhile,Th2 cytokine IL-4 was increased after CTLA4Ig treatment (P =0.044).The same changes were seen in spleen tissues and serum.There was no significant difference in terms of TPOAb between EAT and treated group.Conclusion Local thyroid injection of CTLA4Ig gene shows the therapeutic effect to same degree on EAT through adjusting the underlying Th1/Th2 imbalance.

Objective To study the clinical characteristic of non puerperal mastitis and estimate the effect of anti-mycobacterial agents for non puerperal mastitis .Methods 22 cases of periductal mastitis and gran-ulomatous mastitis receiving anti-mycobacteria drugs therapy from Mar .2012 to Mar.2014 were retrospectively analyzed.Results All patients were female.The mean age was 30 years(ranging from 24 to 46 years).The main clinical manifestation of the 22 patients were 18 patients(81.8%)with mass, 20 patients(90.9%)with abscess, 15 patients(68.2%)with fistula and 9 patients(40.9%)with all of the above 3 symptoms.6 patients had incision and drainage of abscess and 2 patients had tumor resection before anti-mycobacterial therapy .All of the 8 patients had postoperative recurrence .All patients underwent anti-mycobacterial therapy with 3 to 16 months.11 cases (50.0%)patients were cured without recurrence until now .7 cases(31.8%) patients were improved markedly and they still received drug treatment .2 cases(9.0%)patients with tumor size reduced to 2 cm were ready to sur-gical resection.2 cases(9.0%)were lost to follow-up.Conclusion Patients with refractory non puerperal masti-tis can be treated with anti-mycobacterial agents with relatively long treatment time and can also avoid mastecto-my.

Objective To study the clinical features of senile salivary gland neoplasms. Methods A total of 104 cases of senile (beyond 60 years old) salivary gland tumors treated in the past 15 years were analysed. Results Among the 104 cases of senile salivary gland tumors, benigns(85.6%) was more than malignants; males(76.0%) was more than females, the ratio of M∶F was about 1.5∶1. Seventy-two cases(69.2%) were from the parotid gland, 19 (18.3%) from the submandibular gland, 6 (5.8%) from the sublingual gland, 7 cases(6.7%) from the minor salivary gland. Warthin tumor (34 cases) accounted for 32.7%(34/104) of all senile salivary gland tumors, and 47.2%(34/72) of senile parotid gland tumors, 54.8%(34/62) of benign parotid gland tumors. Conclusions The senile salivary gland tumor were mainly benign tumor; Warthim tumor is the most commonly seen and the parotid gland is the most frequently targeted organ. The incidence in males is higher than in females, patients at 60-70 years old (76.0%) are the main victims. Regional excision of parotid gland (resection of tumor together with its surrounding glands) was efficient for surgical treatment in the elderly.

Objective To compare the traditional electrophysiological testing with modified methods for differential diagnosis of Radial Tunnel Syndrome (RTS).Methods A total of 87 selected patients were initially diagnosed as Lateral Epicondylitis (LE) or Tennis Elbow (TE) by doctors from the Outpatient Department of Orthopedics and Rehabilitation.Medical history was asked.Patients received physical examination and examinations for the sensory nerve action potential (SNAP) of superficial radial nerve,the compound muscle action potential (CMAP) of radial nerve and needle electromyography (EMG) to record the muscle Motor Unit Action Potentials (MUAPs).Then,the modified methods for CMAP of radial nerve were conducted on the forearm in the neutral,pronation and supination positions.Three values of CMAP latency were compared.RTS was diagnosed when the difference value ≥0.3 ms.The x 2 test was used to compare the positive detectable rates of the two methods for the RTS diagnosis.Results Thirteen out of 87 patients were diagnosed as RTS,among which three had interosseous nerve lesion and one had superficial radial nerve lesion.The traditional EMG failed to diagnose the remaining 9 RTS cases.These patients were finally diagnosed due to their latency difference of radial nerve CMAP ≥0.3ms when their forearms were examined in three positions.Conclusion The modified electrophysiology method shows a higher positive rate for the diagnosis of RTS.(P＜0.05).

This paper is a follow-up study of 329 children in factory-run nurseries in urban Shanghai. The investigation lasted for a period of one year for each index-child, focusing on the conditions of nutrition, development and diseases of the children of various ages.Comparison between nutritionl findings and RDA of China disclosed that calorie intake of most of the index-child groups were 80-85% of RDA, the only exception being the 6-12 months group where the average calorie intake showed 90%. Protein intake of all groups was over 80% of RDA. Fe intake was lower than RDA, except for 18-month-old and over.Weight and height of the children were compared with the anthropo-metric data established in 1985 (1985 data) for Shanghai children under six years of age. It was found that the average weight and height appeared differently according to their age. Average weight of children under one year old was slightly higher than 1985 data, while average height was lower than 1985 data once the children reached 10 months old. Average weight, however, became lower than the 1985 data after the children were two years old. Over 60% of the index between 6-18 months old suffered from anemia (IDA).Accordingly, it is requested that calorie and iron intake should be supplemented.
