The prevalence and adjusted rate of Mental Retardation(M. R.) were 2.70% and 2.68% in the Qin-Ba Mountain Area in South-Shaanxi; 2.78% and 2.80% in childhood respectivety. These rates were all higher than overall rates in Shaanxi and in It is obvious that the prevalence of M. R. could be reduced by the social-environmental factors such as natural geographic situation, social development level, mean income per capita, mother's schooling, the family relationship with stepmother/stepfather, etc. Reducing prevalence rate of M. R., we need to take the multiple measures and services. It may help the reduction of M. R. prevalence and it is very important to continuously supply iodine salt in these area.

Ohjective To study the indications,clinical effect and complications of hysterectomy so as to im- prove therapeutic effect.Methods The clinical data involving 320 cases of hysterectomy in this hospital from 2000 to 2006 were reviewed,and the pathogenesis,operation mode,curative effect and post-operation complications were analysed.Results Patients who received hysterectomy due to benign gynecologic diseases were cured well cliniclly; those who received hysterectomy due to malignant gynecologic diseases or diseases with the tendency of malignant change were cured well in early stage but the effect was not so satisfactory in later stage.The operation mode was de- cided by considering the pathogenesis and individual difference.Conclusion For benign gynecologic diseases,hys- terectomy can be conducted with good effect after conservative treatment becomes ineffective.For malignant gyneco logic diseases,early treatment will bring good resuh,while late treatment will generate not so satisfactory effect.Indi- cations for operation should be controlled strictly for hysterectomy to guard against complications.

Objective:To investigate the preventive effect of nalmefene on sufentanil-induced cough in the patients with general anesthesia. Methods:Eighty patients with general anesthesia were randomly divided into the control group and the nalmefene group. The nalmefene group was intravenously given 0. 25μg·kg-1 hydrochloric acid natrium nalmefene 5 minutes before the induction, and physiological saline with the same capacity was given in the control group. Cough number and intensity in one minute after the injection of nalmefene were observed, and the changes of hemodynamic indices such as the blood pressure, heart rate and pulse oxygen satura-tion before the anesthesia induction (T0), 1min after sufentanil injection (T1) and after the intubation (T2) were observed and com-pared between the groups. Results:The incidence rate of cough was 37. 5% in the control group and 0% in the nalmefene group, and the incidence rate and strength of cough in nalmefene group were both lower than those in the control group (P<0. 05). The hemody-namic parameters at T1 showed notable changes when compared with those at T0 in the control group (P<0. 05), and had significant differences when compared with those in the nalmefene group (P<0. 05), and at T2, all the parameters recovered to the levels at T0. The parameters in the nalmefene group were much more steady than those in the control group (P>0. 05). Conclusion:Pretreatment with hydrochloric acid natrium nalmefene can prevent sufentanil-induced cough response during the induction of anesthesia without weakening the inhibitory effect of sufentanil on intubation response.

Objective To study and analyze the curative effect of linezolid in the treatment of severe pneumonia and the psychological countermeasures. Methods 100 cases of severe pneumonia patients treated in our hospital from March 2015 to August 2016 were selected and randomly divided into the control group and the experimental group. Two groups of patients according to the actual situation of patients with nutritional support and supplement electrolyte based treatment. The control group was treated with levofloxacin and ceftriaxone infusion treatment, the experimental group underwent intravenous linezolid therapy, and psychological care, pay attention to the psychological status of patients and patients, strengthen communication and exchanges, increase confidence in the treatment and the treatment compliance of patients. The therapeutic effects of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, the number of invalid cases in the experimental group was 4 cases, the number of effective cases was 31 cases, and the number of effective cases was 15 cases. The number of invalid cases in the control group was 10 cases, the effective number was 26 cases, and the effective cases were 14 cases. The effective rate of treatment in the experimental group was 92.0％, which was significantly higher than that in the control group, and the effective rate was 80.0％, with statistical difference (P<0.05). There were no obvious adverse reactions in the experimental group and the control group. The rate of adverse reactions in the control group was 14.0％, significantly higher than that in the experimental group (2.0％), and there was a statistical difference (P<0.05). Conclusion Linezolid is effective in the treatment of severe pneumonia, it can improve the therapeutic effect to a certain extent, and it has high security, it has the significance of clinical promotion.

Objective To explore the relationship of preoperative hemoglobin concentration and use of hospital resources.Methods 108 patients receiving cardiac surgery in the central hospital of wuhan were included.The relationship of preoperative hemoglobin concentration was explored on blood transfusion rates,return to the operating room for bleeding and/or cardiac tamponade,postoperative intensive care unit(ICU)and in-hospital length of stay,and mortality.Results For every 10-unit increase in hemoglobin(g/L),blood transfusion requirements were reduced by 8.0%,6.0%,and 3.0% for red blood cell units,platelet pools,and fresh frozen plasma units,respectively.For each 10-unit decrease in hemoglobin(g/L),the probability(over time)of discharge from the ICU and hospital increased 7.0%,16.0% respectively.Conclusion A lower preoperative hemoglobin concentration resulted in increased use of hospital resources after cardiac surgery.Therefore,the correction of decreasing preoperative hemoglobin concentration could improve the use of hospital resources after cardiac surgery.

Although the efficacy of tyrosine kinase inhibitor (TKI) for the treatment of chronic myeloid leukemia (CML) is obvious, the drug resistance is still inevitable, therefore, TKI drug resistance has become one of the reasons for the failure treatment of CML. According to the literature, about 5 % patients have primary resistance to TKI, and 20 %-30 % patients have secondary resistance to TKI. Current TKI drug resistance molecular mechanisms include the over-expression of bcr-abl, gene mutation, defect of DNA repair mechanism, medicine excretion mediated by ATP-binding cassette translocator, abnormal signaling pathway and bone marrow microenvironment. Meanwhile, the occurrence of drugs, based on the drug resistance mechanism development in preclinical or clinic investigation stage, are likely to provide the possibility for the overcoming of TKI drug resistance. This paper will review the progress of molecular mechanism of TKI drug resistance and the therapy strategy after drug resistance.

Objective To analyze the adverse events following immunization(AEFI) in Changning District of Shanghai in 2006,evaluate the safety of vaccines,and provide the evidence for establishing the safe monitoring system of standard vaccination.Methods The AEFI cases were collected and reported by the Vaccine Adverse Events Surveillance System(VAESS).The data were classified as nonserious,serious reaction according to the symptoms and medical records.Results In 2006,178 AEFI cases related to 12 kinds of vaccines from 126459 doses of 19 kinds of vaccines.Among the adverse events reported,amount of nonserious and serious events were 166 cases and 12 ases respectively.The most commonyl reported type of non-serious adverse events were low-grade fever and non-serious local reaction.AEFI cases caused by DTP combined vaccine was in the first rank.Supplementary immunization of DTP combined vaccine had more cases of AEFI than routing immunization.Conclusions Establishing and perfecting the standardized VAESS will improve the susceptibility and the utilization rate of data on AEFI.To reduce the AEFI,we should implement vaccination regulations,distinguish contraindications,and introduce safer vaccines.

Objective To explore influence of antibiotics and Jiuyi Dan combined with incision-thread-drawing procedure on perianal abscess patients' level of activin A (ACTA) and C-reactive protein (CRP).Methods120 cases of perianal abscess patients in our hospital during March 2015 to December 2016 Coloproctology were selected, they were divided into the experiment group and the control group by random number method.All of patients were taken incision-thread-drawing procedure.Then the experimental group were given nine one antibiotics and Jiuyi Dan, the control group were given antibiotics.The cure rate, 6months after the recurrence rate, average healing time of the wound, and wound edema rate of two groups were observed.Levels of ACTA and CRP expression levels of two groups of patients before and after operation were analyzed.ResultsPatients in the experimental group cure rate was 96.7% higher than that of the control group (P<0.05), the recurrence rate of patients in the experimental group than in the control group, the difference was not statistically significant;the patients in the experimental group the average healing time was (20.67±3.22) d shorter than the average healing time of patients in the control group (29.48±3.15) d, patients in the experimental group wound edema rate of 5% was significantly lower than in the control group 20% (P<0.05);3D ACTA, the expression level of CRP was significantly higher than the preoperative 7 d levels after operation in the two groups (P<0.05);after 7d, the expression level of the two groups of patients with ACTA and CRP were significantly lower than the preoperative level of expression of 7d (P<0.05), experimental group levels of ACTA were significantly lower than the control group, the difference was statistically significant (P<0.05);postoperative 14d patients, ACTA levels of two groups were significantly lower than the levels before operation (P<0.05).ConclusionPerianal abscess can be treated effectively and patients levels of Acta and CRP were obviously dereased by Jiuyi Dan combined with incision-thread-drawing procedure combined, postoperative inflammatory reaction could be importantly alleviated, it was worth clinical promotion.
