RESUMO
Objective:To investigate the effect of anoxic cold environment at 4500 m altitude on female men-struation.Methods:From March 1 to March 20,2023,women in a unit at an altitude of 4500 meters were selected for reproductive health questionnaire survey,and were divided into≤6 months group,6 months to 12 months group and≥12 months group according to altitude exposure time.The changes of menstruation in each group were analyzed to explore the relevant influencing factors.Results:The total incidence of abnormal menstruation in working women in hypoxic cold environment was as high as 66.14%,and there was no statistically significant difference between the groups at different high-altitude exposure times(P>0.05).The highest incidence of dys-menorrhea among the types of menstrual changes was 61.90%,but there was no statistically significant differ-ence between the groups at different high altitude exposure times(P>0.05).There was a statistically significant difference(P<0.05)in the proportion of insufficient sleep for at least 3 days per week,nervousness and anxiety,and training during their menstrual period in the women who experienced changes in their menstrual cycle com-pared to those who did not.Conclusions:Hypoxic cold environment can lead to the change of female menstrua-tion,and it is combined with sleep deficiency,tension and anxiety,and menstrual exercise.
RESUMO
Objective:To establish the reference interval of serum triglyceride (TG) for 4 hours after meal in healthy middle and old people of Beijing community, and to provide the diagnostic basis for the judgment of dyslipidemia after meal.Methods:Selected 369 elderly people from January to October 2018 in the health examination of Guang′anmen Hospital of the Chinese Academy of Traditional Chinese Medicine. The subjects collected fasting venous blood samples in the morning the next day after fasting for 12 hours, then ate a standard breakfast that conformed to the local dietary habits, and collected venous blood samples again 4 hours after eating. Serum TG levels were measured 4 h after meal using AU5822 fully automatic biochemical analyzer and matching reagents. The comparison of postprandial TG between different age and sex groups was statistically significant using the nonparametric test of two independent samples, and the comparison between postprandial and fasting TG using the nonparametric test of two paired samples with P<0.05 as the difference. The 95% confidence interval was calculated using a nonparametric method according to the relevant requirements of the CLSI EP28-A3c file, and the reference interval was expressed as P2.5, P97.5. Results:The median 4-hour post-prandial TG of the middle-aged and elderly aged 45-59 years and those aged ≥ 60 years at health checkups were 1.65 (1.25, 2.13) mmol/L and 1.58 (1.25, 2.00) mmol/L, there was no significant difference between the two groups ( Z=-1.040, P>0.05). There was no statistical difference between males 1.69 (1.22, 2.31) mmol/L and females 1.63 (1.26, 2.12) mmol/L at 4 hours postprandial TG levels in the 45-59 year-old group ( Z=-0.179, P>0.05),there was also no statistical difference between 1.64 (1.22, 2.06) mmol/L for men and 1.53 (1.28, 1.99) mmol/L for women aged 60 years or older ( Z=-0.256, P>0.05).Compared with the median fasting TG of 1.05 (0.87, 1.29) mmol/L, the median serum TG of 1.61 (1.25, 2.09) mmol/L at 4 hours after meal was significantly increased ( Z=-16.449, P<0.01). The difference between postprandial and fasting was 0.52 (0.30, 0.85) mmol/L.The reference range of serum TG at 4 hours after meal was 0.82 to 3.02 mmol/L. Conclusion:In this study, the reference range of serum triglycerides for 4 hours after meal was established in some healthy elderly population groups in Beijing.
RESUMO
Objective:The current systematic review aims to evaluate the effectiveness and quality of interventions on depressive symptoms of informal caregivers of people with dementia in China and to provide evidences regarding protocols for the most effective interventions.Methods:A systematic literature search of Chinese and English databases was performed, covering randomized controlled trails published up to March 2019. The papers for final review were selected based on the inclusion and exclusion criteria. Data were extracted and analyzed with RevMan 5.3, after a quality appraisal of the included studies.Results:A total of 17 papers were identified as eligible for descriptive analysis and 14 of the papers provided estimates for meta-analysis, with 991 participants. An overall mean reduction in depression was identified among the participants of intervention group, compared to those in the control group ( SMD value was -0.75, 95% CI -0.88 - -0.62, P<0.01). Psychotherapeutic ( SMD value was -0.59, 95% CI -0.78 - -0.40, P<0.01) and psychoeducational interventions ( SMD value was -0.84, 95% CI -1.02 - -0.67, P<0.01) showed significant reductions of depressive symptoms among the caregivers. In addition, Evidence exists for the effectiveness across from the short-term ( SMD value was -0.54, 95% CI -0.82 - -0.26, P<0.01), medium-term ( SMD value was -0.68, 95% CI -0.83 - -0.52, P<0.01) to the long-term interventions ( SMD value was -0.80, 95% CI -1.08 - -0.53, P<0.01). Conclusion:Interventions targeting to reduce depressive symptoms are effective among informal caregivers of persons with dementia in China. However, insufficient evidences are found regarding the most effective protocols and more high-quality studies are needed for the target population.
RESUMO
Objective:To analyze the clinical characteristics of neonatal enteroviral meningitis.Methods:A retrospective analysis was conducted on 87 cases with intracranical infection.The cerebrospinal fluid(CSF)samples of these neonates were collected and tested by polymerase chain reaction(PCR) for enterovirus.According to the results, the cases were divided into the positive group(55 cases) and negative group(32 cases). The clinical characteristics of the cases were collected.Results:The time in hospital of the positive group was shorter than the negative group[(9.5±5.2)d vs.(21.8±15.8)d, t=4.295, P<0.001]. The cure rates of the positive group was higher[96.4%(53/55) vs. 81.2%(26/32), χ2=3.872, P=0.049]. There was no death case in the positive group, while there were 3 death cases(9.4%, 3/32)in the negative group.In summer and autumn, the morbidity of the positive group was higher[96.4%(53/55) vs.62.5%(20/32), χ2=17.181, P<0.001]. In two groups, the most predominant clinical presentation was fever[90.9%(50/55) vs. 68.8%(22/32), χ2=6.962, P=0.008]. CSF examination results showed that white blood cells, the proportion of polymorphonuclear cell and CSF protein in the positive group were lower than those in the negative group, while the proportion of mononuclear cell and CSF glucose level in the positive group were higher( P<0.001). Blood and CSF cultures were negative in the positive group.There were 10 cases whose blood cultures and CSF cultures were positive in the negative group.Among them, there were 3 cases infected by group B streptococcus, 6 cases by E. coli, 1 case by Chryseobacterium meningosepticum.The prognoses of the CSF culture positive cases were poor.The abonormal cases detected by cerebral ultrasound, MRI and aEEG were fewer in the positive group( P<0.05). Conclusion:Enterovirus is the common pathogen of nonbacterial meningitis in summer and autumn in our region.The prognosis of enteroviral meningitis is better.Neonates with suspected clinical presentation, such as fever, should undergo PCR test to check CSF for enteroviru.

RESUMO
<p><b>OBJECTIVE</b>To study the clinical and pathologic features of gliosarcoma of cerebral hemispheres.</p><p><b>METHODS</b>The clinicopathologic features of 10 cases of gliosarcoma involving cerebral hemispheres were reviewed. Immunohistochemical study was carried out using EnVision method.</p><p><b>RESULTS</b>The mean age of the patients was 54 years and the male-to-female ratio was 6 to 4. Clinical symptoms included headache (6/10), nausea/vomiting (5/10), and sensory or motor impairment (4/10). Nine of the cases were primary gliosarcoma, with maximum diameter ranging from 2.4 to 5.5 cm (mean = 4.2 cm). The remaining case represented secondary gliosarcoma involving skull base and extracranial tissues. Histologic examination showed a biphasic pattern in all cases. Regarding the glial component, there were 9 cases of pleomorphic glioblastoma and 1 case of giant cell glioblastoma. Reticulin stain was positive in all cases. Immunohistochemical study showed that the tumor cells variably expressed GFAP (10/10), p16 (4/10), EGFR (1/10), CD68 (1/10) and p53 (6/10). The Ki-67 index ranged from 15% to 70% (mean = 34%). Six patients had follow-up data available. One patient was disease-free for 45 months and 5 patients died of the disease at 3 to 17 months after the operation (mean duration of survival = 9 months).</p><p><b>CONCLUSIONS</b>Gliosarcoma is a highly aggressive tumor, often locates in the deeper part cerebral hemispheres and has a relatively short duration of symptoms. It carries a poor prognosis. GFAP immunostain and reticulin stain are helpful in confirming the diagnosis. p53 and p16 are also expressed in some cases.</p>

Besides normal medicine and first-stage institution-based rehabilitation similar with that of control, rehabilitation group received a standardized third-stage community-based rehabilitation. They were assessed with the National Institutes of Health Stroke Scale (NIHSS), Fugl-Meyer Assessment (FMA), Modified Barthel Index (MBI) and Modified Rankin Scale (MRS) before, 1 month and 6 months after treatment. Results The scores of the FMA and the MBI of the rehabilitation group were higher than that of the control group (P<0.01), while were lower of the NIHSS and MRS in the rehabilitation group than in the control group at the end of the sixth month (P<0.01). Conclusion The third-stage community-based rehabilitation may improve the recovery of the stroke patients with hemiplegia.
RESUMO
Objective To explore the histological morphological features of complications following liver transplantation. Methods In 639 patients with complications following liver transplantation, the percutaneous liver biopsy tissues were stained by HE method. Van Gieson, Masson, PAS, reticulin and immunohistochemical staining were performed. HBsAg, HBcAg, HCVAg, CMV-EA, CMV-LA, CMV pp65, EBVAg and the expression of CK19 were detected. The rejection was graded according to Banff standard and scored with RAI.Results 906 times of liver biopsies in 639 cases were performed. Acute cellular rejection (ACR) was most commonly seen in 386 cases ( 42.61 %), followed by complication of biliary tract (251 cases, 27.70 %), drug-induced liver damage (72 cases, 7.95 %), CMV infection (55 cases, 6.07 %), infection or recurrence of hepatitis virus (B or C) (45 cases, 4.97 %), ischemia-reperfusion injury (42 cases, 4.64 %), chronic rejection (32 cases, 3.53 %), obstruction of efferent tract (6 cases, 0.66 %), recurrence of the primary affection (5 cases, 0.55 %), and non-function of live grafts (4 cases, 0.44 %). The complications in 8 cases were difficult to diagnose ( 0.88 %). Compared with the previous report of complications, the incidence rate of ACR was decreased and that of complication of biliary tract and drug-induced liver damage increased in this study. Conclusion Percutaneous liver biopsy is valuable for the diagnosis of complications. It provides the evidence of settling plan of treatment and improves the survival rate.
