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 investigate the modification effect of atmospheric temperature on outpatient visits caused by O3 in Linzhi City. Methods The daily outpatient data, the daily O3 concentration and daily meteorological data (including daily average temperature, average relative humidity, etc.) in Linzhi City from 2018 to 2019 were collected. The distributed lag non-liner-model (DLNM) was used to quantitatively evaluate the impact of O3 in different temperature layers on the risk of outpatient visits. Results At low temperature layers, the cumulative relative risk (CRR) of total outpatient visits and non-injury outpatient visits increased by 53.8%(4.2% -126.9%) and 59.1%(5.8% -139.2%)for every 10 μg/m3 increase of O3 concentration, respectively. The subgroup analysis showed that for every 10 μg/m3 increase of O3 concentration at low temperature, the CRR of patients with circulatory diseases, men, women, and people being <14 years old and 14-65 years old increased by 152.1% (15.1% - 451.9%), 58.3% (2.1%-145.5%), 49.2% (3.0% -116.1%), 39.6% (2.5% - 90.3%), and 61% (0.8%-157.1%), respectively. Conclusion The average temperature may have a modifying effect on the outpatient visits caused by O3 in Linzhi City. In general, the cumulative risk increases as the temperature decreases.

OBJECTIVE To report on concurrent mutations of APC and MLH1 genes identified in a family affected with familial adenomatous polyposis(FAP). METHODS The proband was diagnosed with FAP based on her clinical manifestation, family history and histopathology examination. She developed endometrial epithelial neoplasia(EIN) two years later. With peripheral blood samples collected from her and members of her family, genomic DNA was extracted, and mutations of the APC and MLH1 genes were analyzed by Sanger sequencing. RESULTS Two novel heterozygous mutations were identified respectively in the APC gene(c.637C>T, p.R213X) and the MLH1 gene(c.1153C>T, p.R385C) in the proband. The former has resulted in a truncated protein, while the latter has led to substitution of Arginine by Cystine. CONCLUSION The concurrent mutations of the APC and MLH1 genes probably underline the FAP and Lynch syndrome(LS) in this pedigree. As the first female identified with such mutations, the proband manifested later onset of symptoms with certain degree of variation. For patient with FAP, a detailed family history should be taken.Potential mutation of the APC gene should be screened.Non-intestinal manifestations should be searched. For those who have developed endometrial lesion such as EIN, mutation of the MMR gene (associated with LS) should also be screened.

【Objective】 To summarize the CT and MRI imaging features of gallbladder neuroendocrine tumor.【Methods】 CT and MRI data of 10 patients with gallbladder neuroendocrine tumors proven by surgical pathology between January 2010 and May 2018 were retrospectively analyzed. Among them,6 patients underwent CT examination,3 underwent MRI examination,and 1 patient underwent both CT and MRI examinations. The size,morphologic features and contrast enhancement pattern of gallbladder tumors,and the presence of liver metastasis,bile duct and perihepatic metastasis,lymph node metastasis,and the presence of gallbladder stone were assessed.【Results】Among these 10 cases of gallbladder neuroendocrine tumor,the largest dimension of tumors ranged from 39 mm to 120 mm. The tumors manifest? ed as a mass protruding into the lumen with a broad base adhering to the wall of the gallbladder. In 7 patients who had undergone CT examination,the tumors manifested as an irregular mass with soft tissue density on CT. In 4 patients who had undergone MRI,the tumors showed homogeneous iso-intense signal on T1-weightedimaging,heterogenous hyper-intense signal on T2- weighted imaging,and limited diffusion on diffusion- weighted imaging. All tumors in 10 patients showed moderate,heterogeneous and persistent enhancement. Eight patients had liver metastasis,among whom 7 had metastases in liver segments 4 and 5,and 1 had multiple metastases in other liver segments. Six patients had bile duct invasion and 3 had hilar fat invasion. Seven patients had lymph node metastasis. One patient had gallstone.【Conclusion】Gallbladder neuroendocrine tumor has certain characteristic CT and MRI findings,such as a large mass in gallbladder,which tends to invade adjacent liver parenchyma,and extend along gallbladder neck and gallbladder ducts,accompanied with hepatic portal and retroperitoneal lymph node metastasis,and hilar fat invasion.

This study was carried out by the methods of typical plots investigation and laboratory test aiming at analyzing the survival state and fruiting characteristics of three Sinopodophyllum hexandrum populations in different environmental habitats. Meanwhile, it could provide scientific basis for enhancing wild population quantity recovery. The results showed that more population quantity grow in the habitats of large-area gap (Population A) and bushes (Population C) with a majority of the young individuals, while the minor-area gap (Population B) was the opposite. The development tendency of S. hexandrum populations would be the recession in the future. Spatial distribution pattern of populations was clumped at small scales but random at large scales. The indexes of population A and C, as fruit size,the quantity and quality of seeds,germ inability,were all superior to those of population B. Comparing the mainly environment factors of three populations, that favorable environmental factors for vegetative and reproductive growth of S. hexandrum populations were found,especially certain lighting intensity and fertile soil. Therefore, the favorable environmental habitats for S. hexandrum individuals growth could be artificial to promote the recovery and quantities of S. hexandrum populations in the future.

Objective:The incidence of infections in patients with malignant hematologic diseases is extremely high and significantly affects their prognosis.Identifying early and precise biomarkers for infection is crucial for guiding the treatment of infections in these patients.Previous studies have shown that procalcitonin(PCT)can serve as an early diagnostic marker for bloodstream infections in patients with malignant hematologic diseases.This study aims to compare serum PCT levels in these patients with different pathogens,disease types,infection sites,and severity levels. Methods:Clinical data and laboratory results of infected patients with malignant hematologic diseases treated at the Department of Hematology,the Third Xiangya Hospital of Central South University from January 2018 to August 2023 were collected.General patient information was retrospectively analyzed.Serum PCT levels were compared among patients with different pathogens,types of malignant hematologic diseases,infection sites,and infection severity;Receiver operator characteristic(ROC)curves were used to determine the cut-off values and diagnostic value of serum PCT levels in diagnosing bloodstream infections versus local infections and severe infections versus non-severe infections.Mortality rates after 4-7 days of anti-infective treatment were compared among groups with rising,falling,and unchanged PCT levels. Results:A total of 526 patients with malignant hematologic diseases were included.The main pathogens were Gram-negative bacteria(272 cases,51.7%),followed by Gram-positive bacteria(120 cases,22.8%),fungi(65 cases,12.4%),viruses(23 cases,4.4%),and mixed pathogens(46 cases,8.7%).The main types of malignant hematologic diseases were acute myeloid leukemia(216 cases,41.1%),acute lymphoblastic leukemia(107 cases,20.3%),and lymphoma(93 cases,17.7%).Granulocyte deficiency was present in 68.3%(359 cases)of the patients during infection,with severe infection in 24.1%(127 cases).Significant differences in serum PCT levels were found among patients with different types of pathogens(P<0.001),with the highest levels in Gram-negative bacterial infections.Significant differences in serum PCT levels were also found among patients with different types of malignant hematologic diseases(P<0.05),with the highest levels in lymphoma patients.Serum PCT levels were significantly higher in systemic infections and severe infections compared to local infections and non-severe infections(both P<0.001).ROC curve analysis showed that the cut-off values for diagnosing bloodstream infections and severe infections were 0.22 and 0.28 ng/mL,with areas under the curve of 0.670 and 0.673,respectively.After 4-7 days of anti-infective treatment,the mortality rates of the PCT declining,PCT unchanged,and PCT rising groups were 11.9%,21.2%,and 35.7%,respectively,and pairwise comparisons were statistically significant(all P<0.05). Conclusion:PCT can be used as an auxiliary indicator for early identification of different pathogens,infection sites,and severity levels in patients with malignant hematologic diseases combined with infections.Dynamic monitoring of PCT levels after empirical antibiotic treatment provides important guidance for assessing patient's prognosis.

Objective:To analyze whether triglyceride-glucose (TyG) index is associated with increased risk of cardiovascular diseases (CVD) and the value of TyG index in predicting CVD risk among Kazakh and Uighur population of Xinjiang.Methods:In this study, 5 375 Kazakh and Uygur people of Xinyuan county and Jiashi county were selected as the research objects. Subjects were divided into four groups based on the quartile of the TyG index level. Cox regression model was used to analyze the association between TyG index with the risk of CVD. The dose-response relationship between TyG index and CVD risk was described by restricted cubic splines. The area under the receiver operating characteristic curve, net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were used to estimate the value of TyG index for predicting CVD. Mediating effect analysis was conducted to analyze the mediating effect of TyG index in the association between body mass index and CVD.Results:The age of subjects was 41.06(30.11,53.00)years old, with 46.30%(2 489/5 375)was male. After multivariate adjustment, there was an increasing trend between the risk of CVD and the higher TyG index Ptrend<0.001, compared with subjects of TyG index in Q1, the HR (95% CI) of Q2, Q3, and Q4 groups was 1.53, 1.23 and 1.73, respectively. Restricted cubic splines showed that TyG index was the linearly associated with the risk of CVD. TyG index could improve the prediction ability of Framingham model for the risk of CVD (NRI=0.106, P=0.010; IDI=0.003, P=0.030). The mediating effect analysis showed that in the relationship between body mass index and CVD, the TyG index had a mediating effect ( P<0.001), and the ratio of mediating effect was 12.69%. Conclusion:TyG index is an independent predictor of CVD risk among kazakh and Uygur population in Xinjiang and has a good predictive value for the risk of CVD.

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.
