Antithyroid drugs(ATD)is the main treatment for hyperthyroidism and its adverse reactions have been much concerned by physicians. Methimazole(MMI)and propylthiouracil(PTU)are the two common antitithyroid drugs used currently. Generally, the ATD are safe and effective, though their clinical adverse reactions are also relatively common. The toxic effects include liver damage and leukocytopenia, antineutrophil cytoplasmic antibody-associated pulmonary small-vessel vasculitis, hypoglycemia, allergic reactions, muscle impairment,and so on. They are usually reversible and disappear spontaneously when the drug is discontinued. However,the serious rare side effects can also occur and there may have potentially deadly threatening effects which need to be cautious for the clinicians. MMI is usually preferred over PTU because it has significantly fewer side effects. And unlike the dose-dependent side effects of MMI, there has no significant correlation between adverse reaction and drug dosage in using PTU. Moreover, PTU has more severe hepatotoxity than MMI, even fatal liver impairment and liver failure. The risk of liver damage from PTU is an important concern, particularly in children. For this reason, MMI is the first choice for treating children with hyperthyroidism.

Parathyroid carcinoma is a rare endocrine tumor.Clinical manifestations are varied with multiple organs involved,mainly due to hypercalcemia.So far the etiology and pathogenesis of parathyroid carcinoma are still unclear and preoperatively diagnosis is difficult.Technetium-99 m sestamibi scan and ultrasound can help to find the early lesions.Complete surgical resection with suspicious involved lymph nodes is the recommended treatment.Parathyroid carcinoma is insensitive to chemotherapy and radiotherapy.New immune therapy yields unsure efficacy.Therapeutic effect and prognosis mainly depend on primary surgical resection of the tumor.The disease recurs in more than 50％ of patients with poor prognosis.

Objective: To explore the therapeutic efficacy and mechanism of transcutaneous electrical acupoint stimulation (TEAS) for menopausal insomnia. Methods: A total of 80 patients with menopausal insomnia were randomly divided into a control group and an observation group, with 40 cases in each group. The patients in the control group received conventional Western medication treatment, and the patients in the observation group received TEAS on the basis of conventional Western medication treatment. The treatment for both groups lasted for 4 weeks. Before and after treatment, Pittsburgh sleep quality index (PSQI) and modified Kupperman scale were evaluated, and the serum levels of estradiol (E2) and follicular stimulating hormone (FSH) were measured. The therapeutic efficacy was evaluated after treatment. Results: After treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05); in the control group, the improvement of PSQI score was significant (P<0.05), while the change of modified Kupperman score was insignificant (P>0.05); the PSQI and Kupperman scores in the observation group were significantly improved after treatment (both P<0.05), and there were significant differences between the observation group and the control group in PSQI and Kupperman scores (both P<0.05). After treatment, the serum E2 and FSH levels in the control group were not statistically different from those before treatment (both P>0.05); the serum E2 level was significantly increased (P<0.05), and the FSH level was decreased (P<0.05) in the observation group after treatment, and the between- group differences in serum levels of E2 and FSH were significant (both P<0.05).Conclusion: TEAS plus conventional Western medication in treating menopausal insomnia is effective, and can significantly improve the symptoms of insomnia and menopause, which may be related to the regulation of serum E2 and FSH levels.

The identification and classification of Thermus to Thermales is revie wed. Up to now, the order Thermales is consist of only one family Thermaceae, w h ich includes 4 genera with 14 valid species about 50 strains, and with 4 unvalid spcecies and more than 50 strains unidentified. The morphology, physiology, G+ C mol%, DND hybridization, fatty acid components, 16S rRNA alignment and secondar y structure analyses have been tools for the taxonomy of Thermales.

Objective To explore the characteristics of clinic and epidemiology of neonatal respiratory syncytial virus(RSV) pneumonia in newborn infants.Methods Three hundred and nine neonates(male 196,female 113) who were admitted to children's hospital of Fudan University and identified as having RSV pneumonia from Jan.2004 to Dec.2008 were enrolled.RSV antigen was detected in exfoliated respiratory cells by direct immunofluorescence.All the clinical data were collected and subjects and they were divided into different groups based on path of infection,gestational age and RSV status.Results From case notes over the 5 years,309 eligible neonates with RSV infection were identified.Male term neonates were more likely to acquire infection,as compared to female,1.71.0.The incidence of RSV infection peaked in winter and spring.Compared with community acquired infection group,hospital acquired infection group had more premature infants(23.2% vs 8.7%,P=0.002),lower birth weight[(3 010.8?852.8) g vs(3 153.2?943.4) g,P=0.026],much longer mean length of hospital stay[(19.0?8.0) d vs(12.2?4.5) d,P=0],more expensive cost[(5 646.4?3632.2) RMB vs(4 175.8?2 879.2) RMB,P=0] and later occurrence day[(21.3?8.6) d vs(15.8?6.0) d,P=0].Compared with simple RSV infection group,mixed infection group had more expensive cost[(6 063.1?3 085.4) RMB vs(4 513.2?3 860.8) RMB,P=0.047] and more oxygen use(40.0% vs 25.7%,P=0.006).The clinical characteristics of patients with RSV pneumonia varied.Preterm group compared with term group more frequently exhibited apnea and cyanosis(20.0% vs 0.7%,42.9% vs 22.7%),respectively.Forty-two percent of them had bacterial infection,while 13.3% of them had infection of other part of body.The prognosis of most RSV(99.0%) infections was good.Conclusions RSV was an important cause of respiratory tract infections during the last five years.Clinical characteristics of RSV infections were atypical.Hospital acquired RSV infection was more severe than the community acquired infection in neonates.There are no specific,effective interventions for treating RSV infections,so preventive measures are most important.

ObjectiveTo observe the effect of Batroxobin and Urokinase on brain of diabetic rats following focal cerebral ischemia and reperfusion injury. To investigate the preventive mechanism of Batroxobin following focal cerebral ischemia and reperfusion injury in diabetic rats after thrombolysis therapy.MethodsDiabetic rat was induced by administrating streptozotocin intraperitoneally. Rat model of focal cerebral ischemia and reperfusion injury induced by intraluminal filament occlusion of middle cerebral artery(MCA) that removed 2h later was used. Batroxobin and Urokinase were administrated intravenously in different groups. Infarct volume,cerebral hemorrhage and matrix metalloproteinase (MMP)-2,MMP-9 were detected at 2h,24h,48h after ischemia and reperfusion injury.ResultsThe significant decrease of infarct volume were observed in Batroxobin and Urokinase groups. There were 5 rats observed cerebral hemorrhage in Urokinase group and no cerebral hemorrhage in Batroxobin group. The number of MMP-2 and MMP-9 positive cells in Batroxobin and Batroxobin Urokinase groups decreased compared with saline and Urokinase groups. ConclusionBatroxobin can decrease the infarct volume significantly without the complication of cerebral hemorrhage after ischemia and reperfusion injury in diabetic rats, which maybe relate to down regulation of the expression of MMP-2 and MMP-9.

The quality control of Chinese patent medicines containing animal-derived crude drugs is relatively difficult, because the effective constituents of most animal-derived crude drugs remain unknown. Even if there are relevant methods, they are usually qualitative, and quantitative indicators are either lacking or have poor specificity. This paper has proposed to use molecular quantitative technology to control the quality of Chinese patent medicines containing animal-derived crude drugs. In this study, a molecular quantitative method based on fluorescence quantitative PCR was established for the determination of Jinqian Baihua She in Jinlong Capsule. The method has good specificity, sensitivity, and repeatability. There is a good linear relationship between the content of DNA fragments and the CT (cycle threshold) value. The content of the Bungarus multicinctus-specific fragment in Jinlong Capsule is 24.1-46.6 IU·mg^-1. It is suggested that the content of the specific fragment of Jinqian Baihua She should not be less than 19.3 IU·mg^-1 as one of the quality control criteria of Jinlong Capsule. The study can provide a reference for the quality control of Chinese patent medicines containing animal-derived crude drugs.
