BACKGROUND:Prevention of fractures after stroke is very important,and there are currently no models to predict the occurrence of hip fractures after stroke. OBJECTIVE:To investigate the risk factors leading to hip fracture in stroke patients and to establish a risk prediction model to visualize this risk. METHODS:A total of 439 stroke patients were selected from the Affiliated Hospital of Xuzhou Medical University from June 2014 to June 2017,including 107 males and 332 females,with a mean age of(71.38±9.74)years.They were divided into fracture group(n=35)and non-fracture group(n=404)according to the presence or absence of hip fracture.Univariate and multivariate analyses were used to determine the risk factors for hip fracture after stroke.The data were randomly divided into training set(70%)and test set(30%).Nomogram predicting the risk of hip fracture occurrence was created based on the results of the multifactor analysis,and performance was evaluated using receiver operating characteristic curve,calibration curves,and decision curve analysis.A web calculator was created to facilitate a more convenient interactive experience for clinicians. RESULTS AND CONCLUSION:(1)Univariate analysis showed significant differences between the two groups in the number of falls,smoking,hypertension,glucocorticoids,number of strokes,Mini-Mental State Examination,visual acuity level,National Institute of Health Stroke Scale,Berg Balance Scale,and Stop Walking When Talking scale scores(P<0.05).(2)Multivariate analysis showed that number of falls[OR=17.104,95%CI(3.727-78.489),P=0.000],National Institute of Health Stroke Scale[OR=1.565,95%CI(1.193-2.052),P=0.001],Stop Walking When Talking[OR=12.080,95%CI(2.398-60.851),P=0.003]were independent risk factors positively associated with new hip fractures.Bone mineral density[OR=0.155,95%CI(0.044-0.546),P=0.012]and Berg Balance Scale[OR=0.840,95%CI(0.739-0.954),P=0.007]were negatively associated with new hip fractures after stroke.(3)The AUC values of nomogram were 0.956 and 0.907 in the training and test sets,respectively,and the calibration curves showed a high agreement between predicted and actual status with an area under the decision curve of 0.038 and 0.030,respectively.(4)These findings conclude that the number of falls,low bone mineral density,low Berg Balance Scale score,high National Institute of Health Stroke Scale score,and positive Stop Walking When Talking are risk factors for hip fracture after stroke.Based on this,a nomogram with high accuracy was developed and a web calculator(https://stroke.shinyapps.io/DynNomapp/)was created.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective To investigate serum levels of soluble apoptosis-related factor ligand(sFasL)and stromal cell derived factor 1(SDF-1)in patients with aplastic anemia(AA)and their correlation with immunosuppressive treatment.Methods Forty-three AA patients who received immunosuppressive therapy for half a year were selected as the observation group,and another 43 healthy subjects at the same period were selected as the control group.Patients in the observation group received immunosuppressive therapy and hematopoietic propoietic therapy,and patients were divided into the ineffective group and the effective group according to the efficacy.Clinical data of patients were collected,and serum levels of sFasL,SDF-1,tumor necrosis factor-α(TNF-α)and interleukin-8(IL-8)were detected by enzyme-linked immunosorbent assay.The correlation between serum sFasL and SDF-1 levels was analyzed.Multivariate Logistic regression analysis was conducted to analyze influencing factors of immunosuppressive treatment in AA patients.The predictive values of serum sFasL and SDF-1 on immunosuppressive treatment were analyzed by receiver operating characteristic(ROC)curve.Results Serum levels of sFasL and SDF-1 were higher in the observation group than those in the control group(P＜0.05).Serum levels of TNF-α,IL-8,sFasL and SDF-1 were higher in the ineffective group than those in the effective group(P＜0.05).Serum sFasL level was positively correlated with SDF-1 level in AA patients(r=0.534,P＜0.001).Increased serum sFasL and SDF-1 levels were independent risk factors for ineffective immunosuppressive therapy in AA patients(P＜0.05).The area under the curve(AUC)of serum sFasL and SDF-1 combined to predict the immunosuppressive treatment effect of AA patients was 0.973(95%CI:0.872-0.999),which was better than that of single diagnosis(P＜0.05),and its sensitivity and specificity were 94.44%and 96.00%,respectively.Conclusion Serum levels of sFasL and SDF-1 are significantly increased in patients with AA.The combined detection of sFasL and SDF-1 has high predictive value for the immunosuppressive treatment effect of AA.

Objective:By analyzing the clinical phenotypic characteristics and gene sequences of two patients with Treacher Collins syndrome（TCS）, the biological causes of the disease were determined. Then discuss the therapeutic effect of hearing intervention after bone bridge implantation. Methods:All clinical data of the two family members were collected, and the patients signed the informed consent. The peripheral blood of the proband and family members was extracted, DNA was extracted for whole exome sequencing, and Sanger sequencing was performed on the family members for the mutation site.TCOF1genetic mutations analysis was performed on the paitents. Then, the hearing threshold and speech recognition rate of family 2 proband were evaluated and compared under the sound field between bare ear and wearing bone bridge. Results:In the two pedigrees, the probands of both families presented with auricle deformity, zygomatic and mandibular hypoplasia, micrognathia, hypotropia of the eye fissure, and hypoplasia of the medial eyelashes. The proband of Family 1 also presents with specific features including right-sided narrow anterior nasal aperture and dental hypoplasia, which were consistent with the clinical diagnosis of Treacher Collins syndrome. Genetic testing was conducted on both families, and two heterozygous mutations were identified in the TCOF1 gene: c. 1350_1351dupGG（p. A451Gfs*43） and c. 4362_4366del（p. K1457Efs*12）, resulting in frameshift mutations in the amino acid sequence. Sanger sequencing validation of the TCOF1 gene in the parents of the proband in Family 1 did not detect any mutations. Proband 1 TCOF1 c. 1350_1351dupGG heterozygous variants have not been reported previously. The postoperative monosyllabic speech recognition rate of family 2 proband was 76%, the Categories of Auditory Performance（CAP） score was 6, and the Speech Intelligibility Rating（SIR） score was 4. Assessment using the Meaningful Auditory Integration Scale（MAIS） showed notable improvement in the patient's auditory perception, comprehension, and usage of hearing aids. Evaluation using the Glasgow Children's Benefit Inventory and quality of life assessment revealed significant improvements in the child's self care abilities, daily living and learning, social interactions, and psychological well being, as perceived by the parents. Conclusion:This study has elucidated the biological cause of Treacher Collins syndrome, enriched the spectrum of TCOF1 gene mutations in the Chinese population, and demonstrated that bone bridge implantation can improve the auditory and speech recognition rates in TCS patients.

Objective: To analyze the survival time of reported HIV/AIDS and influencing factors of Yunnan Province from 1989 to 2021. Methods: The data were extracted from the Chinese HIV/AIDS comprehensive response information management system. The retrospective cohort study was conducted. The life table method was applied to calculate the survival probability. Kaplan-Meier was used to draw survival curves in different situations. Furthermore, the Cox proportion hazard regression model was constructed to identify the factors related to survival time. Results: Of the 174 510 HIV/AIDS, the all-cause mortality density was 4.23 per 100 person-years, the median survival time was 20.00 (95%CI:19.52-20.48) years, and the cumulative survival rates in 1, 10, 20, and 30 years were 90.75%, 67.50%, 47.93% and 30.85%. Multivariate Cox proportional risk regression model results showed that the risk of death among 0-14 and 15-49 years old groups were 0.44 (95%CI: 0.34-0.56) times and 0.51 (95%CI:0.50-0.52) times of ≥50 years old groups. The risk for death among the first CD4⁺T lymphocytes counts (CD4) counts levels of 200-349 cells/μl, 350-500 cells/μl and ≥501 cells/μl groups were 0.52 (95%CI: 0.50-0.53) times, 0.41 (95%CI: 0.40-0.42) times and 0.35 (95%CI: 0.34-0.36) times of 0-199 cells/μl groups. The risk of death among the cases that have not received antiretroviral therapy (ART) was 11.56 (95%CI: 11.26-11.87) times. The risk for death among the cases losing to ART, stopping to ART, both losing and stopping ART was 1.66 (95%CI:1.61-1.72) times, 2.49 (95%CI:2.39-2.60) times, and 1.65 (95%CI:1.53-1.78) times of the cases on ART. Conclusions: The influencing factors for the survival time of HIV/AIDS cases were age at diagnosis in Yunnan province from 1989 to 2021. The first CD4 counts levels, antiretroviral therapy, and ART compliance. Early diagnosis, early antiretroviral therapy, and increasing ART compliance could extend the survival time of HIV/AIDS cases.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

Blood loss and blood transfusion requirement are important quality control indicators of cardiovascular surgery and cardiovascular anesthesia. Patient blood management (PBM) is an evidence-based, multidisciplinary approach to optimizing the care of patients who may need transfusion, which encompasses anemia management, hemodilution, cell salvage, hemostatic treatment, and other approaches to reducing bleeding and minimizing blood transfusion. PBM in cardiovascular surgery is a "team sport" that involves cardiac and vascular surgeons, anesthesiologists, perfusionist, intensivists, and other health care providers. The current work provides an overview of evidence and practice of PBM at Fuwai Hospital. Implementation of PBM should also take local resource availability and cost-effectiveness of different devices, drugs, technologies, and techniques into consideration.

Abstract: Objective　To study the characteristics and diagnostic efficacy of Rose-Bengal plate agglutination test (RBPT), standard-tube agglutination test (SAT) and enzyme-linked immunosorbent assay (ELISA) in the diagnosis of brucellosis. Methods　A total of 489 suspected brucellosis patients with complete records, who admitted to Xing'anmeng People's Hospital from March 2020 to May 2021, were selected as the subjects. The diagnostic value of SAT, RBPT and ELISA for brucellosis was analyzed with exposure history + clinical symptoms + serological test/brucellosis isolation and culture as the gold standard. Results　Of the 489 suspected patients, 183 (37.42%) were diagnosed with brucellosis, while 234 (47.85%), 148 (30.27%) and 195 (39.88%) were positive by RBPT, ELISA and SAT, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of RBPT in the diagnosis of brucellosis were 95.08%, 80.39%, 74.36%, 96.47%, and 85.89%, respectively; the values of the above parameters for ELISA were 78.69%, 98.69%, 97.30%, 88.56%, and 91.21%, respectively; those values of SAT were 98.36%, 95.10%, 92.31%, 98.98%, and 96.32%, respectively. The sensitivity of RBPT was significantly higher than ELISA, but the specificity and accuracy were significantly lower than ELISA (all P<0.05). The sensitivity and accuracy of SAT diagnosis were significantly higher than ELISA, but the specificity was significantly lower than ELISA (all P<0.05). There was no significant difference between SAT and RBPT in the sensitivity of diagnosis, but the specificity and accuracy were significantly higher than those of RBPT (P<0.05). Conclusion　RBPT and SAT have high sensitivity in diagnosis of brucellosis, while ELISA has high specificity in diagnosis. RBPT with high sensitivity and convenient operation can be used for primary screening in field detection, and then the other two methods can be used for rechecking, so as to further improve the efficiency and accuracy of diagnosis of brucellosis.

One new and two known dammarane-type saponins were isolated from the leaves of Gynostemma pentaphyllum using various chromatographic methods. Their structures were identified by HR-ESI-MS,~( 1)H-NMR, ~(13)C-NMR, 2 D-NMR spectra as 2α,3β,12β,20,24(S)-tetrahdroxydammar-25-en-3-O-[β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl]-20-O-β-D-xylopyranosyl(1→6)-β-D-glucopyranoside(1, a new compound, namely gypenoside J5) and 2α,3β,12β,20,24(R)-tetrahdroxydammar-25-en-3-O-[β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl]-20-O-β-D-xylopyranosyl(1→6)-β-D-glucopyranoside(2) and 2α,3β,12β,20-tetrahydroxy-25-hydroperoxy-dammar-23-en-3-O-[β-D-glucopyranosyl(1→2)][β-D-glucopyranosyl]-20-O-[β-D-xylopyranosyl(1→6)]-β-D-glucopy-ranoside(3), respectively. Compounds 1 and 2 were a pair of C-24 epimers. All compounds showed weak cytotoxicity agxinst H1299, HepG2, PC-3, SH-SY5 Y cancer cell lines. However, they exerted protective effect against SH-SY5 Y cellular damage induced by H_2O_2 dose-dependently, of which compound 1 displayed the strongest antioxidant effect. The present study suggested that G. pentaphyllum has antioxidative potential and the saponins from G. pentaphyllum are considered as the active compounds with neuroprotecitve effect.

Objective: To investigate the safety and efficacy of ultrafiltration on diuretic sensitivity in heart failure patients with reduced ejection fraction and diuretic resistance. Methods: This was a single-center randomized controlled trial. A total of 148 heart failure patients with reduced ejection fraction admitted to the Hospital of Traditional Chinese Medicine of Xinjiang Uygur Autonomous Region from June 2010 to June 2020 were enrolled in this study, and these patients were randomly divided (ratio 1:1) into the ultrafiltration group (n=74) and the control group (n=74). All patients were treated with diuretics, cardiotonic, vasodilator and other comprehensive drugs according to relevant guidelines. After grouping, the patients in the control group were treated with standard treatment plan, while patients in the ultrafiltration group were treated with ultrafiltration on top of standard therapy. Diuretic drugs were discontinued during ultrafiltration, and intravenously furosemide (40 mg) was given immediately and 24 hours after the end of ultrafiltration. Clinical data including gender, age, complicated diseases, New York Heart Association (NYHA) function classification, etc. were collected. Effectiveness indicators include urine volume (the first 12-hour and 24-hour urine volume and the second 24-hour urine volume after using diuretic), body weight and dyspnea severity score. Safety indicators include systolic blood pressure, serum creatinine, serum Na⁺ concentration, blood K⁺ concentration and the number of deaths before and after intervention. Results: Two patients in the control group died due to worsening heart failure after randomization and were excluded in this study, 146 patients were finally analyzed (72 patients in the control group and 74 patients in the ultrafiltration group). There were 93 males, and the age was (68.3±11.2) years. There was no significant difference between patients in the ultrafiltration group and the control group in gender, age, body weight, course of disease, dyspnea severity score, NYHA function classification Ⅲ/Ⅳ, the proportion of patients with severe edema of both lower limbs, the proportion of patients with complicated diseases, and basic medication (all P>0.05). After using diuretics, the urine volume of the first 12-hour and 24-hour and the second 24-hour were significantly higher in the ultrafiltration group than in the control group (all P<0.05). Body weight decreased significantly after ultrafiltration treatment as compared with that before intervention in the ultrafiltration group (P<0.05). Compared with the control group, the dyspnea severity score was significantly improved in the ultrafiltration group (P<0.05). There was no significant difference in systolic blood pressure, serum creatinine, serum Na⁺ concentration, blood K⁺ concentration of patients between ultrafiltration group and control group before and after intervention (all P>0.05). During the clinical diagnosis and treatment, 2 male patients in the control group died, and the cause of death was aggravation of basic diseases complicated with acute heart failure and cardiogenic shock. There was no death in the ultrafiltration group, and there were no obvious clinical adverse events during and after ultrafiltration. Conclusion: Ultrafiltration therapy is safe and can improve diuretic sensitivity in heart failure patients with reduced ejection fraction and diuretic resistance.
