Background: Up to now, there are quite number of studies on the origin and role of the nervous apparatus in controlling the kidney. However, in some articles, the authors do not fully highlight the anatomic morphology of renal nervous plexus and providing the rule of structure and distribution of the cell\u2019s components, nerve fibers in the nervous plexus. Objective: A study on the anatomical characteristics of renal nervous plexus of Vietnamese adults. Subject and methods: Based on the anatomical study by macroscopic and microscopic dissection with the micro MBC-2 on nervous plexus of 60 renal pedicles of adults at the age of 18-70 years. Results and Conclusion: The structure of renal nervous plexus is very complex. This plexus is formed by many nerve fibers and pedicles and is widely connected with perirenal nervous tissue. Beside, it has also the close connection between left and right plexus for the guarantee of nervous distribution with bilateral replacement. Thick concentrations of renal nervous plexus is not only at the renal sinus region, but also at the renal hilum, where the distribution of renal arterial branches. There are many nervous ganglion tissues in the renal nervous plexus. These ganglia are smaller than from aortorenal ganglion to intrasinual ganglion.

Background: Bach Thong, a mountainous district has large terrain withouta local district hospital. The commune health stations are newly built or upgraded and with added equipments, however this still does not reach national standards. The knowledge and practices in reproductive health care and population planning for families are still inadequate. Objectives: To discover various factors related to the reproductive health of women from 15 to 49 years old in Bach Thong district, Bac Kan province. Subjects and method: A descriptive, cross sectional study assesses the situation of knowledge and practice on the reproductive health of 15-49 age women at Bach Thong district, Bac Kan province in March, 2006. Results:Mass media were related to the context of pregnancy examinations, behavior of short interval of between births, having numerous children for women in the researched area. Women literacy level was related to awareness on negative affects of giving birth to over 3 children and at a young age. Household's income was related to the options of birth control method. Conclusion: It is recommended that the authorities, health service offices, population-family and children sectors need to enhance the primary health care as well as health care for women.

Objective:To explore the relationship between glycosylated hemoglobin (HbA1c)and carotid artery atheroscle-rosis in aged patients with normal glucose tolerance.Methods:A total of 100 aged patients with normal glucose tolerance were selected.Their bilateral carotid arteries were measured by color Doppler ultrasonography.They were grouped accord-ing to carotid intima-media thickness (C-IMT,normal,thicken and atherosclerosis)and plaque form (no plaque,hard plaque and soft plaque);blood pressure,blood lipids and HbA1c etc.were compared among groups.Results: (1)Along with CIMT rose,there was significant increase in HbA1c level [(4.98 ± 0.55)% vs.(5.51 ± 0.42)% vs.(5.92 ± 0.39)%],and there was significant difference between any two groups (P<0.01 all);(2)HbA1c level was (5.36±0.51)%,(5.89±0.44)% and (5.97±0.2)% in no plaque group,hard plaque group and soft plaque group respectively,and there was significant difference among hard plaque group,soft plaque group and no plaque group (P <0.01 all).Conclu-sion:Glycosylated hemoglobin may become an important index assessing carotid atherosclerosis in aged people.

Objective To study the pattern of intragastric acid secretion in bleeding ulcer patients to assess the role of gastric acid suppression in the prevention and treatment of ulcer bleeding.Methods 43 cases of peptic ulcer(PU) with ulcer bleeding and 53 cases of age-and sex-matched PU controls without ulcer bleeding were included. All patients received 24 hours gastric pH monitoring. PU was diagnosed by endoscopy. Hp infection was diagnosed by rapid urinase test, biopsy and C 13 breath test.SPSS software was used for statistic analysis.Results In bleeding group, average gastric pH in supine was 1 6,and the percent of accumulative time and the longest lasting time within 0～1 of gastric pH in supine were 21% and 26 0 minutes respectively,while in control group those were 2 0%, 4 5 minutes respectively.However, no differences of gastric pH were found between severe bleeding patients and other bleeding ones. Hp infection rate was 56 1%,54 8% in bleeding group and control group respectively.Conclusions Multiple factors might induce peptic ulcer bleeding. Higher gastric acid secretion at night might be one of the risk factors causing peptic ulcer bleeding.It is suggested that giving PU patients with a high risk of bleeding some acid inhibitor before sleeping may prevent PU hemorrhage. Hp infection may be the direct risk factor leading to ulcer bleeding.

Objective:To explore the directed forgetting ability of elder people to disease/death-related words under the conditions of the neutral and negative emotion.Methods:Thirty-six elder people and thirty-seven young people were included in this study.The directed forgetting effects to disease/death-related words were compared by using item-method directed forgetting paradigm under the neutral and negative emotional conditions.Results:Under the neutral and negative emotion conditions,higher recognition of to-be-remembered (TBR) than to-be-forgotten (TBF) words in elder group and younger group (Ps ＜ 0.05).The elder group showed the weaker effect of directed forgetting than younger group[neutral emotion:(0.4 ± 0.1) vs.(0.6 ± 0.1);negative emotion:(0.3 ± 0.1) vs.(0.7 ± 0.04),Ps ＜ 0.05].Under the negative emotion condition,elder people showed stronger effect of directed forgetting for sensitive words compared with control words[(0.4 ± 0.1) vs.(0.1 ± 0.1),P ＜ 0.001].Conclusion:The results suggest that the directed forgetting ability of elderly is weaker than that of young individuals,the ability of non-sensitive words than that with sensitive words,and the directed forgetting effect of elder people tonon-sensitive words in negative emotion is weaker than that in neutral emotion.

Objective To study the effect of propofol intravenous anesthesia on T helper cells of patients with primary liver cancer during perioperative period.Methods A total of 86 patients with primary liver cancer in our hospital from November 2014 to October 2015 were selected,who were divided into observation group and control group according to the method of random numbers,43 cases in each group.The observation group were taken propofol intravenous anesthesia,and the control group were treated with sevoflurane inhalation anesthesia.The Th1 cells percentage,Th2 cells percentage and the ratio changes of the Th1/Th2 cells of two groups before anesthesia and postoperative 1 day were compared.The plasma cortisol levels of two groups before anesthesia,after anesthesia,intraoperative and 1 day after operation were observed.Results The percentage of Th2 cells in observation group and control group 1 day after surgery had no significant difference (P ＞ 0.05).The percentage of Th1 cells and Th1/Th2 cells ratio of the observation group were higher than those of the control group [(16.32 ± 1.76) ％ vs.(14.16 ± 1.03),(8.48 ± 0.92) vs.(7.11 ± 0.72)],the differences were significant (P ＜ 0.05).The plasma cortisol levels of observation group during operation and 1 day after operation were lower than those of the control group[(12.34 ± 1.02) μg/dL vs.(16.13 ± 1.26) μg/dL,(12.01 ± 0.94) μg/dL vs.(15.25 ± 1.08) μg/dL],the differences were significant(P ＜ 0.05).Conclusion The propofol intravenous anesthesia can encourage more Th to differentiate into Th1 cells,which plays a protective role in the patient's immune function.

Microglia are the principal immune effectors in brain and participate in a series ofneurodegenerative diseases. The microglial shapes are highly plastic. The morphology is closely related with their activation status and biological functions. Cerebral ischemia could induce microglial activation, and microglial activation is subjected to precise regulation. Microglia could play either protective or neurotoxic roles in cerebral ischemia. Therefore, regulating the expression of receptors or protein molecules on microglia, inhibiting the excessive activation of microglia and production of pro-inflammatory factors, promoting the release of neuroprotective substances might be beneficial to the treatment of cerebral ischemia. The study about relationship between microglia and cerebral ischemia will shed a light on the treatment of cerebral ischemia. This paper is a review of microglial activation and regulation during cerebral ischemia as well as related therapeutic methods.

Background and purpose:Neuroendocrine neoplasm is one kind of infrequent neoplasms from neuroendocrine cell and peptidergic neurons. This study aimed to investigate the epidemiology and clinicopathological characteristics of neuroendocrine neoplasms (NEN) in Dalian. Methods: We retrospectively analyzed all neuroendocrine neoplasms patients in First Afifliated Hospital of Dalian Medical University from 2000 to 2013. The epidemiology characteristics, pathogenic sites and pathological types were reviewed, and the differences between gender and age were also analyzed. The statistics analysis such as independent-samples t test and one-way ANOVA and chi-square test were performed. Results:There were 279 NEN cases, including 166 male and 113 female patients (male:female=1.14:1), detection rate was 0.258%. The mean age of all cases was 59.4±17.1 (20-83), for male 58.9±19.4 (20-81) and female 61.7±15.0 (29-83). There was no statistical signiifcance of detection rate and mean age between male and female patients. Digestive system was the most common occurred site of NEN (71.68%), then was the respiratory system (20.79%). There was no statistical significance of pathogenic sites between male and female.In all case, 132 with neuroendocrine tumor (47.31%), 140 with neuroendocrine cancer (50.18%), 7 with mixed adenoneuroendocrine carcinoma (2.51%). There was no statistical signiifcance of pathological types between male and female (P>0.05).Conclusion:Recently, the detection rate of neuroendocrine neoplasms was raised in Dalian, but there was no signiifcance differences in detection rate,pathogenic sites and pathological types between male and female.

Objective To investigate the genotype-phenotype correlation between TSC1 and TSC2 associated tuberous sclerosis complex(TSC).Methods Nineteen infants with TSC were enrolled in the study.Their clinical manifestations and mutations of TSC gene were analyzed by chip capturing and next-generation sequencing.Results Among the total of 19 patients with TSC,13 TSC2 mutations and 4 TSC1 mutations were detected.The ratio of TSC2/TSC1 mutation-positive cases was 3.4/1.Six mutations were novel.There were epilepsy in 10 cases carrying TSC2 mutations,including 4 cases (31％) with refractory to antiepileptic treatment,and 3 cases carrying TSC1 mutations,including 1 case (25 ％)with refractory to antiepileptic treatment.The incidence and severity (grade 2)of epilepsy,brain imaging were not different in TSC2 and TSC1 patients(P =0.480 7,0.462 2).Compared with clinical manifestations,incidence of mental retardation (grade 1 or grade 2) was higher in TSC2 patients (85 ％,11/13 cases) than TSC1 patients (50 ％,2/4 cases).Also,the incidence of moderate and severe mental retardation (grade 2) was higher in TSC2 patients (54％,7/13 cases) in comparison with TSC1 patients(25％,1/4 cases).Compared with the phenotype of TSC2 and TSC1 patients,the frequencies of skin,renal and cardiac lesions were significantly higher in TSC2 patients than TSC1 patients.Conclusions TSC2 mutation may be the prominent molecular pathogenesis in Han population with TSC.TSC2 patients have much profound muhisystemitc leisions than TSC1 patients,including mental retardation,epilepsy,facial angiofibromas and renal angiomyolipomas etc,which should be confirmed further in domestic multicenter and large samples.
