Hypothyroidism is one of the most common endocrine disorders in childbearing or pregnant women.Gestational hypothyroidism can increase the incidence rate of the variety of pregnancy complications and adverse pregnancy outcome.It also can make adverse effects on the fetus and neonate,such as death,placental abruption,fetal malformation,intrauterine growth retardation and preterm,low birth weight,neonatal respiratory distress syndrome,it can also cause abnormal thyroid function of neonate,severely can cause nerve,mental,physical and mental developmental abnormalities and even death.Therefore,it is recommended that childbearing women who are at high risk for pregnancy should strengthen to monitor pregnancy thyroid function and treat as soon as possible in order to reduce the adverse effects on offspring.

OBJECTIVE: To evaluate the current situation and trend of narcotic drug use in our hospital where the authors work in order to provide the reference for scientific management and rational use of these drugs. METHODS: The yearly amount of narcotic drugs administered in the whole hospital, the yearly amount in the separate departments, as well as drug expenditures and ratios between January 2002 and November 2005 were added up and analyzed statistically. RESULTS: The amount of bucinnazine use dominated in the first. The amount of morphine for oral use was increasing year by year. The amount of fentangl transdernal patch use was also bigger and increasing rapidly. However, the amount of pethidine and morphine for injection use was decreasing. CONCLUSION:Analgetics for oral and transdermal use will be the main categories of analgetics in the future.

Objective To explore the characteristics of TCM syndromes of acute coronary syndrome(ACS). Methods Clinical data of 127 ACS patients were collected and then a database was established.After that,the distribution of syndrome patterns was analyzed.Results The incidences of the following excess syndrome patterns were in a decreasing sequence:stasis syndrome,phlegm syndrome,cold syndrome and heat syndromes.The incidence of stasis syndrome was 90.5%,which was much higher than other excess syndromes.The incidences of the following deficiency syndrome patterns were in a decreasing sequence:heart-Qi deficiency syndrome,heart-Qi exhaustion syndrome,heart-yin deficiency syndrome,heart-Qi depletion syndrome,heart-kidney deficiency syndrome and heart-blood deficiency syndrome.The incidence of heart-Qi deficiency syndrome was 75.6%,which was much higher than other deficiency syndromes.The incidences of the stasis syndrome and cold syndrome in acute myocardial infarction(AMI)were higher than those in unstable angina(UA),and the incidences of heart-Qi deficiency syndrome and heart-Qi exhaustion syndrome in AMI were higher than those in UA(P

0.05). Other raw scores of MMSE in the vascular dementia group were lower than those in the cerebral infarction group and the normal control group ( P 0.05). P 300 peak latency in the vascular dementia group prolonged significantly as compared with that in the cerebral infarction group and the normal control group ( P

Bedside ultrasonography is used to provide information about the cardiovascular system and the function and anatomy of certain internal organs,and help to guide the invasive procedures.Compared to traditional ultrasonography,bedside ultrasonography is more focused on the optimization of the treatment.It has become a necessary tool,as a powerful adjunct to the physical examination,in the management of critically ill patients in advanced countries.The development trend is the clinical protocol based on bedside ultrasonog-raphy.The application of bedside ultrasonography in China is limited,especially in PICU.Standardized educa-tion and quality assurance system are needed to its popularization.

Objective To study the T Lymphocyte Subsets and the cytokines in the newborns with infectious diseases. Methods Twenty cases of neonatal bacterial pneumonia (bacterial group), 15 cases of rotavirus enteritis (virus group) and 20 newborns with jaundice (control group) were recruited in this study. The peripheral CD4+T Cells and lymphocyte subsets were assessed by flow cytometry. Results The IL-4 level was significantly different among different groups (F=3.39, P=0.041). The levels of IL-17 and IFN-γdid not differ signiifcantly among different groups (F=0.28 and 1.24 respectively, P>0.05). The IL-4 level was higher in bacterial group than that in virus group and control group (P<0.05). The percentages of CD3+, CD4+, CD19+and NK cells and the ratio of CD4+/CD8+ had significant difference among different groups (F=3.30-26.69, P<0.05). The percentages of CD3+and CD4+cells and the ratio of CD4+/CD8+were lower in bacterial group and virus group than those in control group (P<0.05). The percentage of CD19+cells was higher in bacterial group and virus group than that in control group (P<0.05). The percentage of NK cells was lower in virus group than that in bacterial group and control group (P<0.05). Conclusions The pattern of cytokines level is different in newborns with infection caused by different pathogens. Newborns with infectious diseases have immune dysfunction and Th2-dominated imbalance. The low percentages of T lymphocyte subsets indicate the depressed cellular immunity after infection, which may result in atypical symptom and prolonged disease course.

Gastrointestinal motility disorders are commonly seen digestive system diseases in elderly subjects. During the process of normal aging,digestive tract experiences a series of degenerative changes,which is the foundation of many gastrointestinal motility disorders. Further study on gastrointestinal dysmotility and its mechanisms is of great significance for the diagnosis and treatment of related diseases in aging population. In this article,the advances in studies on effects of aging on motility of digestive tract( including oropharynx,esophagus,stomach,small bowel,colon and anorectum)and its mechanism researches were reviewed.

Objective:To investigate the use of antibacterial drugs during the perioperative period of a cesarean section and observe the differences before and after antibacterial drug remediation. Methods:1 569 cesarean cases from 2010 to 2012 were investigated, and the use of antibacterial drugs, drug categories, drug combinations, medical expenses, and so on was statistically analyzed with the use of the statistical software SPSS13. 0. Results:The rate of antibacterial drug usage within the 1 569 cesarean cases was 100%;for pre-operative antibacterial drug remediation, azithromycin, cefathiamidine, and ornidazole were the top three, while the top three antibacterial drugs for post-oper-ative remediation were arecefathiamidine, cefuroxime, and clindamycin. There was no significant difference between the two groups of incision infections, and the rate for combined use of drugs dropped. The analysis of drug costs is of statistical significance. Conclusion:The analysis of antibacterial drug remediation is useful for the rational use of anti-bacterial drugs and a reduction of costs.

Objective To observe the effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on the proliferation of chondrocytes and metabolism of human osteoarthritis (OA) in short-term (48 hours). Methods The human knee OA chondrocytes were cultured in the presence or absence of NSAIDs (celecoxib, diclofenac and ibuprofen). BrdU assays were used to evaluate the effects of NSAIDs on the proliferation of OA chondrocytes. ELISA was used to detect the contents of pro-teoglycan and type-Ⅱcollagen in chondrocytes and culture supernatant. The differences of those indexes were compared be-tween groups. Results The positive rate of BrdU labelling index of chondrocytes increased significantly in ibuprofen group than that of other groups (P<0.05). The content of type-Ⅱcollagen in the culture supernatant increased significantly in di-clofenac group than that of other groups (P<0.05 or P<0.01). The content of proteoglycan in the culture supernatant in-creased significantly in ibuprofen group than that of other groups (P<0.05 or P<0.01). There were no significant differences in the content of type-Ⅱcollagen and proteoglycan between chondrocytes of NSAIDs groups (P>0.05). Conclusion Ibu-profen may stimulate the proliferation and the secretion of proteoglycan of human OA chondrocytes. Diclofenac may stimu-late the secretion of type-Ⅱcollagen of human OA chondrocytes. There were no effects of celecoxib on the proliferation and metabolism of human OA chondrocytes.
