Objective To understand and to assess the current situation of iodine deficiency disorders in Qaidam Basin,and to provide the information for measures and strategies of prevention and cure of this disease.Methods Within the boarder of Qaidam,five counties(cities)were selected for the investigation,which were Delingha,Golmud,Dulah,Wulan,and Tianjun.Two townships(towns)have been selected in each county(city),51 students aged 8 to 10 in one of the primary schools in each township(town)underwent thyroid palpation examination,their urine samples were collected to test urine iodine using arsenic-Ce catalysis spectrophotometric method.Thirty students of fifth-grade class in the selected schools underwent the questionnaire of prevention knowledge of iodine deficiency disease,while 10 housewives in each village near by the school were asked for the same questions,and the edible salt in their home was quantified of iodine by using direct titration method.Results Among the children aged 8 to 10,the average prevalence rate of thyroid enlargement Was 5.9%(30/510),higher than that stipulated by the national standard.The median of urinary iodine of urinary iodine level for children aged 8 to 10 was 83.4μg/L,the ration of urinary iodine＜20μg/L Was more than 10 percent;qualified iodized salt consumption rate of residents was 59.0%(118/200);the average scores and the checkout rate of fifth-grade students and the housewives who had underwent the questionnaire survey were 31.5,12.0%(36/300)and 35.9,18.5%(37/200)respectively.Conclusions The prevention and cure of iodine deficiency disorders in selected area do not work well,iodized salt is not popular,therefore health education needs to be strengthened.

OBJECTIVE:To establish a set of scientific,standard management model and rational,impartial financial system in Chinese institutes for drug control.METHODS:The types of the established institutions and the financial appropriation model of institutes for drug control in China were studied by using the methods of classification,comparison and analysis.RESULTS & CONCLUSIONS:Under super-ministry system,local management in drug control institutions at all levels is expected to be put into practice soon.It is advisable to optimize the organization and management model and financial appropriation management system such as by shifting from county level institution to district level institution and carrying out a wage system in drug control institutes in accordance with the payment level of civil servants,etc.

OBJECTIVE:To provide references for the accountability of civil liability induced by different causes.METHODS:Literature retrieval and case study were applied to analyze the civil liability of pharmaceutical manufacturers and medical institution in medication misadventures.RESULTS & CONCLUSIONS:At present it is difficult for patients who suffered from medication misadventures caused by drug quality defects,drug adverse reaction or medication errors to claim.The main reasons are imperfect relevant law system and the vacancy of compensation mechanism of drug-induced injury events.It is suggested to establish technology institution for evaluating medication misadventures,state relief and compensation system and encourage pharmaceutical manufacturers to buy products liability insurance.

Systemic lupus erythematosus (SLE) is a serious multisystem autoimmune disease with different clinical manifestations.Childhood-onset SLE (cSLE) is similar to adult-onset SLE, while its morbidity and mortality are higher than adults, and it is prone to damage important organs.Therefore, early diagnosis and treatment are very important.With the in-depth exploration of the pathogenesis and the development of cell and molecular biology, the progress of drug therapy for SLE has been promoted.Immunosuppression still remains the cornerstone of treatment, and glucocorticoids still plays a leading role.Biologics bring the gospel to SLE patients, and non-specific immunotherapy gains treatment time for refractory and severe SLE patients.Treatment options are led by the level of disease severity.It is of great significance to understand the treatment progress of cSLE and combine theory with practice together to control the disease activity and improve the prognosis.This article reviews recent advances regarding the update on the treatment of cSLE in recent years.

The addition of HER2-targeted therapy has markedly improved the survival and prognosis of patients with advanced gastric cancer. Inhibiting the HER2 signaling pathway has become the backbone treatment for advanced HER2-positive gastric cancer in the first-line setting. TOGA trial established trastuzumab in combination with cisplatin and 5-flurouracil as the standard first-line treat-ment. In the post-TOGA era, combinations of trastuzumab with other chemotherapy agents were proven to be effective as both the second-line treatment and the conversion treatment. Such combinations are promising in the neoadjuvant treatment for locally ad-vanced gastric cancer. Research focuses on the development of novel anti-HER2 agents in combination with agents targeting against other signal pathways. Real-time monitoring of the gene expression profile is the key to discovering the mechanism of trastuzumab re-sistance. The preliminary results of existing clinical trials have shown potential to overcome resistance to trastuzumab. In this review, we summarized the treatment advancement for HER2 positive gastric cancer and the direction for future development, thereby provid-ing guidance on clinical practice.

The etiology and pathogenesis of Crohn’s disease(CD)are not fully clear,and genetic susceptibility, immunologic disorder,intestinal barrier dysfunction and intestinal microecology are considered to be involved in the pathogenic mechanism of CD. In recent years,the relationship between intestinal microecology and CD has received much attention. Several studies confirmed that the intestinal microecology in CD patients was different from that in normal person. The change of intestinal microecology was correlated with the occurrence of CD,and modulation of intestinal flora was effective in the treatment of CD. This article reviewed the relationship between intestinal microecology and CD and the therapeutic prospect of intestinal microecology for the treatment of CD.

To explore the state of domestic academic research on hospital administration, the authors, using the descriptive statistical method, investigated the literature on hospital administration included by CBMdisc from 1980 to 1998. The results are as follows. In the past 19 years, the output of literature on hospital administration has been growing steadily. The distribution of such literature has been rather dispersed. There lacks a specialized and ampre- hensive database of such literature. Chinese Journal of Hospital Administration and Chinese Hospital Administration are two major professional periodicals devoted to literature on hospital administration, publishing one fifth of the literature in this aspect. And Chinese Journal of Hospital Administration, the chief and most important key periodical devoted to literature on hospital administration, has become a professional periodical which is indispensable and of first choice to hospital administration personnel.

Objective:To analyze the clinical features, treatment efficacy and prognosis of cavernous lymphangioma.Methods:The clinical manifestations, laboratory findings, imaging examinations and treatment of 8 patients with pathology-diagnosed cavernous lymphangioma admitted in Peking Union Medical College Hospital from January 1990 to July 2020 were retrospectively analyzed.Results:All the patients were female. The onset age ranged from 0 to 58 years, with a course of 24 (5,78) months. There were 2 cases of abdominal mass, 2 cases of axillary mass, 1 case of neck mass, 1 case of inguinal mass, 1 case of mandibular mass and 1 case of pleural and peritoneal effusion. Seven cases had adult onset and 1 case had congenital onset. Two patients had had history of surgery adjacent to lesion sites. Contrast-enhanced CT scan showed a low-density round mass with no significant enhancement in 5 patients. Seven patients underwent complete resection of the mass, 1 patient received partial resection and intervention with medium-chain fatty-acid diet. During the follow-up, 4 patients were stable after 3.5 (1.3-17.8) years, while 2 patients relapsed 1 and 13 year after surgery, respectively. Additionally, one patient was diagnosed with Bowen disease.Conclusion:Cavernous lymphangioma can be congenital or acquired and usually occurs in female. The body mass is the common clinical manifestation; and surgery is the most common treatment, but it is prone to relapse and requires long-term follow-up.

AIDS caused by HIV-1, is a major threat to human being. An anti-HIV formulation from Chinese herbs, so called "Qu Du Zeng Ning", have been recently developed. In this work, the pharmacodynamics of the formulation in vitro was studied. The results showed that Qu Du Zeng Ning inhibit the replication of HIV-1 efficiently in all cell-based assay, with IC50 at 105.2, 70.7, 77.4 microg mL(-1), separately. A significant synergy between the formulation and zidovudine (AZT) was observed, and it also showed a potent activity against HIV-1 drug-resistant mutant.
