Objective To discuss the effect of the occurrence of congestive heart failure on the outcome of pregnant women with pulmonary hypertension. Methods Fifty-four pregnant patients complicated with pulmonary hypertension were admitted from January 2000 through December 2010. Among them, 34 had comorbidity of congestive heart failure. The timing and mode of pregnancy termination, and perinatal outcomes were studied, and comparison was made between those with and without heart failure. Results ① Of all 54 pregnant women with pulmonary hypertension, 34 had congestive heart failure. The incidences of congestive heart failure in patients with mild, moderate and severe degree of pulmonary hypertension were 27.78% (5/18), 73.33% (11/15) and 85.71% (18/21), respectively (P<0.05).②The rate of maternal complications was 47.06% (16/34) and maternal mortality was 17.65% (6/34) in the patients with combined pulmonary hypertension and heart failure. The rate of iatrogenic fetal loss was 29.41% ( 10/34) , preterm labor 52.94% (18/34), neonatal asphyxia 35.29% (12/34) and neonatal mortality 23.53% (8/34) in case of patients with pulmonary hypertension complicated with congestive heart failure. ③The rate of Cesarean section was 91. 18% (31/34) in the patients with combined pulmonary hypertension and heart failure. ④ The rates of iatrogenic induction, premature delivery, maternal complications and mortality, neonatal asphyxia and fetal or neonatal fatality were significantly higher in women with combined pulmonary hypertension and heart failure than those with simple pulmonary hypertension ( P < 0. 05). Conclusions The risk of heart failure increases with the severity of pulmonary hypertension. The occurrence of heart failure is the most important factor affecting the outcome of patients in pregnancy already complicated with pulmonary hypertension , and Cesarean section is the safer mode of termination of pregnancy in this cohort of women.

Objective To discuss the change trends of pathogen of severe hand,foot and mouth dis-ease(HFMD) in Chaoshan area during 2011 to 2015. Methods All 1410 throat swabs of cases who were diagnosed as HFMD were collected from children hospitalized in our hospital during May 2011 to August 2015. Enterovirus were detected by nest RT-PCR,and the results of these positive cases diagnosed as severe HFMD were analyzed. Results (1) There were 216 positive cases(67. 29%,216/321) diagnosed as severe HFMD,including 53. 70% ( 116/216 ) enterovirus 71 ( EV71 ), 19. 91% ( 43/216 ) coxsackievirus A16 (CA16),12. 04%(26/216) CA6,8. 80%(19/216) CA10,3. 24%(7/216) CA4,0. 93%(2/216) coxsack-ievirus B5, 0. 46% ( 1/216 ) enteric cytopathogenic human orphan virus and 0. 93% ( 2/216 ) unclassified samples were unclassified to species. (2) Five cases of critical HFMD were all caused by EV71. (3) The EV71 positive samples were given priority to severe cases ( 51. 79%,116/224 ) and the non EV71 positive samples were given priority to mild cases ( 82. 08%, 458/558 ) , the difference was statistically significant (χ2 =91. 68,P<0. 001). (4) The change trends of severe HFMD year by year were consistent with the change trends of EV71 composition,and were highly correlated(Rs=0. 9,P=0. 037). (5) Severe HFMD caused by non EV71 virus gradually increased. Conclusion Severe HFMD in Chaoshan area during 2011 to 2015 were mainly caused by EV71,non EV71 viruses including CA16,CA6,CA10,CA4,coxsackievirus B5, enteric cytopathogenic human orphan virus 6 could also develop to severe HFMD. The composition ratio of severe HFMD increased accordingly in the year of EV71 as the dominant pathogen. The proportion of severe HFMD caused by non EV71 virus gradually increased after 2013 year.

Objective: To explore the analgesic effect of electroacupuncture on neuropathic pain and the role of
PI3K/AKT pathway in microglial activation in spinal cord.
Methods: Chronic constriction injury model was established using Sprague-Dawley rats to mimic
neuropathic pain. The pain intensity was then detected by paw withdrawal threshold and thermal
withdrawal latency. Real-time quantitative PCR (qRT-PCR), Western blot were used to evaluate the
activation of PI3K/AKT pathway as well as microglia in L4-5 of all rats. Proinflammatory cytokines
TNF-α and IL-6 were analyzed by Enzyme-linked immunosorbent assay (ELISA). Results: It was
demonstrated that chronic constriction injury-induced hyperalgesia was significantly improved by
LY294002 intrathecal administration and electroacupuncture stimulation at “Zusanli” 足三里 (ST36)
and “Yanglingquan” 阳陵泉 (GB34). Also, treatment with electroacupuncture significantly reduced
the activation of microglia and downregulated the levels of TNF-α and IL-6, which was similar to the
outcomes of LY294002 intrathecal administration. Furthermore, the expression and phosphorylation
of PI3K/AKT signaling was markedly suppressed by electroacupuncture treatment.
Conclusions: These findings indicated that electroacupuncture exhibited the analgesic effect on CCI
rats by inhibiting the activation of microglia and production of proinflammatory cytokines in spinal
cord through blocking the microglial PI3K/AKT signaling activation

PURPOSE:
Rapid decompressive craniectomy (DC) was the most effective method for the treatment of hypertensive intracerebral hemorrhage (HICH) with cerebral hernia, but the mortality and disability rate is still high. We suspected that hematoma puncture drainage (PD) + DC may improve the therapeutic effect and thus compared the combined surgery with DC alone.
METHODS:
From December 2013 to July 2019, patients with HICH from Linzhi, Tibet and Honghe, Yunnan Province were retrospectively analyzed. The selection criteria were as follows: (1) altitude ≥1500 m; (2) HICH patients with cerebral hernia; (3) Glascow coma scale score of 4-8 and time from onset to admission ≤3 h; (4) good liver and kidney function; and (5) complete case data. The included patients were divided into DC group and PD + DC group. The patients were followed up for 6 months. The outcome was assessed by Glasgow outcome scale (GOS) score, Kaplan-Meier survival curve and correlation between time from admission to operation and prognosis. A good outcome was defined as independent (GOS score, 4-5) and poor outcome defined as dependent (GOS score, 3-1). All data analyses were performed using SPSS 19, and comparison between two groups was conducted using separate t-tests or Chi-square tests.
RESULTS:
A total of 65 patients was included. The age ranged 34-90 years (mean, 63.00 ± 14.04 years). Among them, 31 patients had the operation of PD + DC, whereas 34 patients underwent DC. The two groups had no significant difference in the basic characteristics. After 6 months of follow-up, in the PD + DC group there were 8 death, 4 vegetative state, 4 severe disability (GOS score 1-3, poor outcome 51.6 %); 8 moderate disability, and 7 good recovery (GOS score 4-5, good outcome 48.4 %); while in the DC group the result was 15 death, 6 vegetative state, 5 severe disability (poor outcome 76.5 %), 4 moderate disability and 4 good recovery (good outcome 23.5 %). The GOS score and good outcome were significantly less in DC group than in PD + DC group (Z = -1.993, p = 0.046; χ
CONCLUSION
PD + DC treatment can improve the good outcomes better than DC treatment for HICH with cerebral hernia at a high altitude.

Objective To investigate the association between gallstones (GS) and metabolic syndrome (MS) in southern Xinjiang, China, and to provide experience for the prevention and control of metabolic diseases in southern Xinjiang. Methods The patients with GS who visited First Division Hospital, Second Division Korla Hospital, and Third Division Hospital of Xinjiang Production and Construction Corps from March 2015 to March 2019 were enrolled as case group, and cluster sampling was used to select the individuals who underwent physical examination in Third Division 51st Regiment Hospital during the same period of time were enrolled as control group. According to inclusion and exclusion criteria, 1140 cases were enrolled in each group after 1∶ 1 matching based on age and sex. The t -test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups; a logistic regression analysis was used to investigate the influencing factors for GS. Dummy variables were included by logistic regression to evaluate multiplicative interaction between MS components, and the parameter estimate and covariance matrix of the logistic regression model and interaction calculation table were used to calculate and evaluate additive interaction between MS components. Results The risk of GS in MS patients was 2.33 times that in non-MS patients (odds ratio [ OR ]=2.33, 95% confidence interval [ CI ]: 1.86-2.92). In addition, the components of MS also increased the risk of GS, including blood glucose ( OR =2.94, 95% CI : 2.36-3.68), blood pressure ( OR =1.50, 95% CI : 1.26-1.80), blood lipids ( OR =1.48, 95% CI : 1.25-1.75), and body mass index ( OR =1.44, 95% CI : 1.21-1.70). After adjustment for multiple factors, the risk of GS gradually increased with the increase in the number of metabolic abnormalities, i.e., one abnormality ( OR =1.55, 95% CI : 1.22-1.99), two abnormalities ( OR =2.13, 95% CI : 1.66-2.72), three abnormalities ( OR =3.48, 95% CI : 2.59-4.69), and four abnormalities ( OR =4.65, 95% CI : 2.79-7.84). No additive or multiplicative interaction was found between MS components. Conclusion GS is closely associated with MS in southern Xinjiang, and the risk of GS gradually increases with the increase in MS components. No additive or multiplicative interaction is found between GS and MS components.

This study aims at establishing a teaching catalog and content for breast rare diseases and developing the syllabus for the breast rare disease using integrated multimodality of case-/problem-/resource-based learning (CBL+PBL+RBL). By conducting bibliometrics co-occurrence analysis, we collected 6291 articles on breast rare disease published from January, 1975 to June, 2024. Additionally, we retrieved the Textbook on Rare Diseases, the Catalog of Chinese Rare Disease, and Second Batch of Rare Disease Catalog and then decided the teaching content. From 16, 387 keywords, 1000 (6.1%) keywords were identified through co-occurrence analysis, including 50(0.3%) candidate diseases. These were classified into three categories: rare primary breast diseases, rare genetic mutation-related diseases associated with breast cancer, and rare systemic multi-system diseases involving the breast. From the candidate list, 20(0.1%) rare primary breast diseases were further selected for their notable clinical teaching significance, and significant multi-systemic diseases affecting the breast, whether related to gene mutations or not. Teaching plans were drafted using a diversified parallel teaching approaches, taking into account the characteristics of different diseases and the focus of different teaching methods. This study initiated the development of the teaching content for breast rare diseases and developed the teaching syllabus using the CBL+PBL+RBL integrated multi teaching model and targeting each rare breast disease for the critical point for teaching.
