Objective To compare the advantages between CT and MRI examination and to evaluate the applied value of diffusion weighted imaging(DWI) in acute cerebral trauma.Methods 54 cases with cerebral trauma were undergone CT and MRI simultaneously,the advantages and disadvantages of both examination were analysed using self-comparative method. Results In showing subarachnoid hemorrhage, ultra-acute cerebral bleeding and bone fracture,CT was better than MRI,but cerebral contusion in 5 cases,laceration of white matter in 5 cases,acute white matter swelling in 2 cases and subdural haematoma in one case were misdiagnosed by CT.DWI was much better to show laceration of white matter and acute cerebral matter swelling than CT and conventional MRI.Conclusion In diagnosing acute cerebral bleeding and bone fracture, CT is better than MRI, for other diagnoses MRI better than CT. DWI should be applied to be a common scan method in diagnose of acute cerebral trauma.

OBJECTIVE:To standardized declaration of preparation registration in medical institutions. METHODS:With the combination of registration review of new varieties in the preparation registration in medical institutions in Liaoning province from 2010 to 2014,the existing problems in drug registration information of preparation in medical institutions were introduced,and the solutions and suggestions were proposed. RESULTS & CONCLUSIONS:The main problems of registration information of prepara-tion in medical institutions included non-standardized preparation name,unclear topic and writing,inappropriate instructions and la-bels,and imperfect preparation process,etc. To standardize the preparation registration authenticity and integrity of registration in-formation of medical institutions,it is suggested to increase on-site verification efforts,strengthen the five years clinical using his-torical inspection,improve the level of research and development of hospital preparations declaration units,and strengthen the idea that the medical institutions should be responsible for the quality and safety of preparations to ensure the safety and effectiveness.

Objective To evaluate the human resource in a national institute of parasitic diseases from 2007 to 2016，so as to provide a reference for the construction of a well⁃crafted human resource of national parasitic diseases control and prevention. Methods The basic information of the staff in the national institute of parasitic diseases was investigated and a related database was established to analyze the quantity and structure of the human resource allocation in 10 years through the annual statistics each year. Results The number of staff in the institute increased by 6.25% in 2016 compared with that in 2007，and 43.32% of the staff were under 35 years old. In 2016，59.36% of the staff had a master degree or a higher level degree，and 37.97% of the staff had senior technical titles. The difference value of the inflows and outflows was 3.21%. Conclusions The change of the structure and quality of human resource in this institute has a good tendency in the past ten years. The organization should optimize the human resource allocation and improve its capacity in disease control and prevention to broaden the methods of talent introduction and control the brain drain problem.

Objective: To investigate the coverage of rotavirus vaccination among children under five years in Xiuzhou District of Jiaxing City, so as to provide insights into rotaviral diarrhea control. Methods: The rotavirus vaccination data of children aged two months to five years were extracted from the vaccination clinics of eight township hospitals and community health service centers through the Zhejiang vaccination information system. The coverage of rotavirus vaccination was analyzed among children with different genders, ages, types of vaccines and doses of vaccination. Results: Totally 32 752 children were included, and the coverage of rotavirus vaccination was 47.09%. The coverage of rotavirus vaccination was significantly higher in boys than in girls ( 47.65% vs. 46.46%, P<0.05 ), and a higher vaccination rate was seen in children with local household registration than in those without ( 56.76% vs. 38.75%, P<0.05 ). The vaccination rates of monovalent and pentavalent rotavirus vaccines were 36.90% and 10.18%, respectively. Totally 26 982 doses of rotavirus vaccines were vaccinated, with a mean dose of ( 0.84±1.02 ) per capita, and the vaccination rates of one, two and three doses were 20.75%, 17.37% and 8.96%, respectively. The median age was 6.00 months ( interquartile range, 3.00 months ) among children vaccinated with the first dose. Conclusions The coverage of rotavirus vaccination and full-dose vaccination are low among children under five in Xiuzhou District, with monovalent rotavirus vaccines predominant. Intensified rotavirus vaccination is therefore recommended.

Objective : To investigate the fertility level of registered population in Baoshan District, Shanghai Municipality and the incidence of adverse birth outcomes of live births from 2013 to 2022, so as to provide the evidence for improving maternal and child health care strategies. Methods: The data pertaining to live births registered in Baoshan District from 2013 to 2022 were collected through the Shanghai Birth Medical Information System, including the basic information of live births and maternal fertility. The indicators such as fertility level, parity, birth age and incidence of adverse birth outcomes of live births were descriptively analyzed. The trend of crude birth rate and total fertility rate was analyzed by annual percent change (APC). Results: A total of 56 719 live births were registered in Baoshan District from 2013 to 2022. The crude birth rate was 6.54‰, the total fertility rate was 31.78‰, and the sex ratio at birth was 105.61. The crude birth rate showed a downward trend from 2016 to 2022 (APC=-11.054%, P<0.05), and the total fertility rate showed a downward trend from 2017 to 2022 (APC=-10.377%, P<0.05). The proportion of second parity and above showed an increasing trend from 2013 to 2017 (P<0.05) and a decreasing trend from 2017 to 2022 (P<0.05). The maternal childbearing age showed an increasing trend from 2013 to 2022 (P<0.05), the incidence of premature infants and low birth weight infants showed an increasing trend (both P<0.05). The incidence of premature infants and low birth weight infants increased with the rising childbearing age (both P<0.05). Conclusions The fertility level in Baoshan District was relatively low from 2013 to 2022. The proportion of second parity and above showed an upward trend followed by a downward trend. The incidence of premature infants and low birth weight infants increased with the rising childbearing age.

Objective To investigate the schistosomiasis japonica infection and preventive knowledge of immigration popula-tion in Jinshan District,Shanghai so as to provide the evidence for improving the control work. Methods The immigration popula-tion from schistosomiasis endemic provinces and local people were screened by serum IHA screening for schistosome infection, and the positives were further examined by Kato-Katz technique and the miracidium hatching method. The schistosomiasis preven-tive knowledge and behaviors were investigated by questionnaires. Results A total of 579 were investigated with 348 immigration people and 231 local people,and among them,the male accounted for 72.0%and female accounted for 28.0%. In the immigration population,the main age group was 20-29(56.0%),and 56.6%of the immigration had an education level at senior middle school or higher. The most proportion of immigration was from Anhui Province(36.2%). There were 4 IHA positive persons(1.15%)in the immigration,and 1 was positive in the stool test,and the schistosome infection rate was 0.29%. There were no positives in the local people. The schistosomiasis preventive knowledge of the immigration was generally poor,and some people’s behaviors of see doctor and medication were incorrect. Conclusion There are schistosome infected persons among the immigration population from schistosomiasis endemic provinces,and their schistosomiasis prevention knowledge was poor,thus there is a schistosomiasistransmission risk.

This investigation was aimed to explore whether over-expression of 27heme oxygenase-1 (HO-1) could protect bone marrow mesenchymal stem cells(BMSCs)against injury induced by high-concentration glucose. We cultured BMSCs in high-concentration glucose medium, and up-regulated or inhibited HO-1 expression in BMSCs through its agonist or inhibitor. We detected the ability of BMSCs proliferation and secretion respectively by MTT and enzyme-linked immunosorbnent assay (ELISA). Then we detected the effect of BMSCs conditions medium on proliferation and migration of human umbilical vein endothelial cells (HUVECs) through scratch experiments and transwell assay. It was found that HO-1 over-expression could not only promote BMSCs proliferation, but also promote secretion of vascular endothelial growth factor (VEGF), and could further accelerate the proliferation and migration of HUVECs. It could be well concluded that HO-1-over-expressing BMSCs can not only inhibit damage induced by high-concentration glucose, but can promote the proliferation and migration of vascular endothelial cells through paracrine as well. The result indicated that HO-1-over-expressing BMSCs played an important role in the treatment of diabetic vascular complication.

Objective To study the prognostic role of plasma neutrophil gelatinase-associated lipocalin (NGAL) early after renal transplantation.Methods A total of 37 kidney recipients were enrolled from Department of Organ Transplantation,Guangdong Second Provincial General Hospital within a 12-month period of time.Plasma NGAL was measured immediately before and at 6 and 12 h post-transplantation.Changes of serum creatinine were documented daily within the first week postoperation.Acute kidney injury (AKI)/graft rejection during the first week after transplantation was the outcome variable.Results The levels of serum NGAL in the 37 patients were (311.14 ± 102.69),(317.81 ± 107.28) and (312.16 ± 134.80) μg/L respectively immediately before and at 6 and 12 h post-transplantation.There was no significant difference in serum NGAL levels before and 6 h or 12 h after operation (P =0.70,and P =0.96).There were no significant differences in gender and age between the two groups (P =0.29,and P =0.20).There was significant difference in creatinine levels between the AKI group and the non-AKI group (P =0.002) and between pre-operation and 6 or 12 h postoperation.The preoperative levels of serum NGAL in AKI group and non-AKI group were (333.58 ± 116.30) and (300.36 ± 96.15) μg/L (P =0.36),and those were (383.3 ± 147.16) and (286.32 ± 65.97) μg/L (P＜0.01) at 6 h,and (437.33 ± 164.16) and (252.08 ± 57.53) μg/L (P＜ 0.001) at 12 h after operation.The sensitivity and specificity of serumNGAL (317μg/L at 12 h after operation as the cutoff value) predicting AKI was 100％ and 92％ respectively,which was much better than that of serum creatinine at the corresponding time point (sensitivity =66.7％,and specificity =61.9％).Conclusion Plasma NGAL,particularly at 12 h after transplantation,is a very sensitive and specific biomarker for predicting AKI.

Objective To explore the feasibility of serum Klotho level in the elderly donors to predict the renal graft function in the recipients. Methods Clinical data of 16 elderly donors and 27 recipients undergoing renal transplantation were collected. The general status of the recipients was observed. The levels of serum Klotho and serum creatinine (Scr) in the elderly donors were measured on the day of renal transplantation. The Scr levels in the recipients were measured at postoperative 1, 3 and 12 months respectively. The estimated glomerular filtration rate (eGFR) was calculated. The correlation between the serum Klotho level of the donors and postoperative graft function of the recipients was analyzed. Results The cold ischemia time during renal transplantation was (649±245) min. The incidence rate of delayed graft function (DGF) was 26%. The incidence rate of acute rejection was 7%. In the elderly donors, the serum Klotho level was 537 (245-793) pg/mL and the Scr level was (164±62) μmol/L. At postoperative 1, 3 and 12 months, the Scr levels in the recipients were (136±47), (132±43) and (133±46) μmol/L, respectively. The corresponding eGFR was (52±20), (52±19) and (53±21) mL/(min?1.73m²), respectively. The serum Klotho level in the elderly donors was negatively correlated with the renal graft function at postoperative 1 month in the recipients (P < 0.05). The sensitivity and specificity of serum Klotho level in predicting the renal graft insufficiency at postoperative 1 month were 0.909 and 0.769. Conclusions The preoperative serum Klotho level in the elderly donors have predictive value for renal graft function in the recipients at postoperative 1 month.

Objective To investigate the effects of olanzapine combined with metacognitive training on social cognition and insight of schizophrenic patients.Methods One hundred twenty patients with schizophrenia were randomly divided into two groups. All patients received four week treatment. The study gr oup received olanzapine combined metacognitive training treatment and the control group only used olanzapine treatment. The positive and negative symptoms scale (PANSS), the Insight and Treatment Attitude Questionnaire (ITAQ), the Beck Cognitive Insight Scale (BCIS) and Faux Pas Recognition Task (FPRT) were assessed at baseline and after four weeks of treatment. Result There was no statistically significant difference in the scores of all battery between two groups before treatment (P>0.05). the scores of total PANSS and subscales, ITAQ, BCIS and FPRT were statistically significant between study and control groups (P<0.05).After 4 weeks of treatment,the total PANSS scores and subscales scores were significantly lower in the study group than in the control group (P<0.05). The ITAQ score, self-reflection factor of BCIS, composite index and FPRT scores were significantly higher in the study group than in the control group (P<0.05). The difference in self-certainty of BCIS difference was not statistically significant(P>0.05).Differences of the remaining scales were statistically significant(P<0.05). Conclusion Olanzapine combined with metacognitive training has a significant effect on the social cognitive dysfunction in schizophrenic patients,improving the patient's insight and enhancing the social function.
