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 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 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 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.

Objective:To explore the effect of psychological intervention based on Rosenthal effect in esophageal cancer patients with chemotherapy.Methods:From July 2018 to October 2020, 95 patients with esophageal cancer who received chemotherapy in Jiangsu Cancer Hospital were selected as the research object by convenience sampling. The patients were divided into the experimental group (48 cases) and the control group (47 cases) by random number table method. The control group was given routine health education and psychological intervention, while the experimental group received the psychological intervention based on Rosenthal effect. The hope level and self-management ability of the two groups of patients before intervention and after six months of follow-up were compared.Results:Before intervention, there was no significant difference in the hope level and self-management ability between the two groups ( P>0.05) . After six months of follow-up, the scores of hope and self-management ability of the two groups were higher than those before intervention, and those of the experimental group were higher than those the control group, with statistical differences ( P<0.05) . Conclusions:Psychological intervention based on Rosenthal effect can help enhance the hope level in esophageal cancer patients undergoing chemotherapy and improve the patients' self-management ability.

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 investigate the indoor fine particulate matter (PM 2.5 ) pollution and its influencing factors in children s bedrooms using solid fuel, so as to provide evidence for effective strategy to reduce PM 2.5 pollution. Methods: From December 2019 to November 2020, 198 households (108 in the north, 90 in the south) from two pilots in the north(Jiamusi in Heilongjiang Province) and south of China (Mianyang in Sichuan Province) were selected, and status of solid fuels using were obtained through home visits, dynamic changes in PM 2.5 concentrations in children s bedrooms were monitored by using real time online instruments, and the influencing factors of PM 2.5 pollution were analyzed by using a mixed effects model. Results: During the monitoring period, the daily PM 2.5 concentrations in the northern and southern pilot were 78.33 (40.50, 154.80) and 38.54(26.20, 58.46) μg/m 3, respectively, exceeding standard rates of 44.57% and 33.22%. During the heating period, the daily PM 2.5 concentrations in the northern and southern pilot were 212.50(133.60,244.10) and 104.42(73.97, 134.90) μg/m 3, respectively, with over standard rates of 96.75% and 86.96%. The mixed effects model analysis results showed that children s bedroom PM 2.5 concentrations were associated with solid fuel usage duration, window opening time, room layout (shared entrance door between kitchen and bedroom), indoor smoking, indoor humidity, and solid fuel use in the bedroom ( β =0.19, -0.05, 1.20, 0.43, 0.02, 0.35, all P <0.05). Conclusion Solid fuel combustion significantly comtributes to PM 2.5 pollution in children s bedrooms, with more pronounced impacts observed in northern China compared to southern regions.
