Objective To investigate the infection state and genotype of Babesia from tick at Alataw port,the China-Kazakhstan border.Methods Drag-flag method and animal body surface method were used to collect ticks at Ebinur Lake wetland,Alataw port.18s rRNA gene of Babesia was tested by polymerase chain reaction (PCR),the sequence analysis was conducted with Blast and phylogenetic analysis was conducted with Mega 6.0.Results The positive rate of Babesia gene in ticks was 12.65％ (32/253) at Alataw port.By sequencing,32 sequences were divided in ALSK174,ALSK191,ALSK019 three groups.Analysis of Blast showed that ALSK174 had the highest homology with Babesia caballi (EU888904,South Africa),it was 99.72％ (356/357);ALSK191 had the highest homology with Babesia occultans (KP745626,Turkey),it was 99.72％ (350/351);ALSK019 had 95.76％ (339/354) homology with Babesia odocoilei (KC460321,Canada).Conclusion In this study,we have first reported that the Babesia is infected from ticks at Alataw port,the China-Kazakhstan border.

Objective:To investigate the value of ultrasonography in diagnosis of transposition of great arteries of the fetus at 11-13 + 6 weeks gestation. Methods:A prospective study was conducted on fetuses screened by ultrasound in the first trimester in Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region between January 2015 and March 2022. Fetal heart structure was screened by three-section screening method. Fetuses with suspected transposition of the great arteries at 11-13 + 6 weeks gestation underwent followed-up ultrasound examination, chromosome and gene test results. The ultrasound characteristics and prognosis pregnancy outcomes were summarized. Results:Twenty-one cases of transposition of the great arteries were detected by ultrasonography, including complete transposition of great arteries (20 cases) and congenitaly corrected transposition of the great arteries (1 case). Two cases were miss diagnosed. Twenty-one cases showed parallel signs of two major arteries on grayscale outflow section at 11-13 + 6 weeks gestation. There were 6 cases with aneuploid ultrasonographic soft markers abnormality, 2 cases with extracardiac malformation. Chromosome and microarray analysis were performed in 13 cases. 4 cases with chromosomal abnormality. Four cases of chromosomal abnormalities were associated with ultrasonographic soft markers abnormality, and 1 case with extracardiac malformation.In the 23 cases, 20 cases were induced, 1 miscarried, and 2 delivered to term. Among the fetuses delivered at term, 1 case died before neonatal operation and 1 case survived. Conclusions:Standardized ultrasound scan at 11-13 + 6 weeks has high accuracy in diagnosis of transposition of the great arteries. And the incidence of chromosomal abnormality is high with ultrasonographic soft markers abnormality or extracardiac malformation.

Objective:To investigate the value of atrioventricular valve regurgitation in predicting atrioventricular septal defect (AVSD) in the first trimester.Methods:Fetuses were examined prospectively by ultrasound at 11-13 + 6 weeks in Maternity & Child Healthcare Hospital of Guangxi Zhuang Autonomous Region between February 2016 and February 2021. Congenital heart disease was screened and atrioventricular valve regurgitation was observed in fetuses of gestational age 11 to 13 + 6 weeks using color Doppler in four-chamber view and three vessels and trachea view. Results:Totally 43 549 fetuses of gestational age 11 to 13 + 6 weeks were screened by echocardiography, of whom 37 cases were screened out with AVSD, including complete atrioventricular septal defect (31 cases), partial atrioventricular septal defect(3 cases) and intermediate atrioventricular septal defect(1 cases), 2 cases were misdiagnosed, and ultrasonic scanning in the second trimester found 2 missed cases of intermediate atrioventricular septal defect. Atrioventricular valve regurgitation was observed in 91.89% of atrioventricular septal defects (34/37) in the first trimester, 59.46% (22/37) nuchal translucency greater than 95th percentile, 29.73% (11/37) absence of nasal bone, 32.43% (12/37) ductus venosus A wave inversion, and 40.54% (15/37) had tricuspid regurgitation. The sensitivity of common atrioventricular valve regurgitation in predicting atrioventricular septal defect is better than other ultrasonic indexes. Conclusions:Atrioventricular regurgitation can be used as a clue to predict atrioventricular septal defect in the first trimester, which is beneficial to detect atrioventricular septal defect in the first trimester.

Objective:To investigate the long-term efficacy and complications of augmentation uretero-enterocystoplasty (AUEC).Methods:The clinical data of 262 patients with lower urinary tract dysfunction who underwent AUEC at our center from January 2003 to June 2022 were analyzed retrospectively. There were 193 males and 69 females, the median age was 24 (4, 67) years, the median disease duration was 12.0 (0.2, 56.0) years and the preoperative creatinine was 91.5 (68.1, 140.0) μmol/L. 320 ureters had high-grade UUTD, 216 ureters had VUR, 14 of which had low-pressure reflux.The number of low-grade VUR ureter was 22 (10.2%) and the number of high-grade VUR ureter was 194 (89.8%). Video-urodynamics showed that the maximum bladder capacity was 102 (47, 209) ml, the maximum detrusor pressure was 33.0 (15.5, 50.5) cmH 2O, and the bladder compliance was 6.4 (3.0, 12.3) ml/cmH 2O. All patients underwent AUEC. The surgical method is to cut a segment of sigmoid colon, open the sigmoid colon along the mesenteric margin, fold and suture it into " U" or " S" shaped intestinal mesh according to the principle of " detubulization" . At the same time, perform ureteroplasty and replanting, and then anastomosis the intestinal mesh with the opened bladder flap to form an expanded new bladder. Follow-up was performed via outpatient clinic or telephone. The creatinine, maximum bladder capacity, maximum detrusor pressure, bladder compliance, ureteral reflux and upper urinary tract dilatation were compared preoperatively and postoperatively. The postoperative complications were also evaluated. Results:The median follow-up time was 57.4 (4, 151) months after surgery. At 1-3 months after surgery, the maximum bladder capacity and bladder compliance increased to 303.9% and 189.9% of the preoperative level, and the maximum detrusor pressure decreased to 63.6% of the preoperative level. At 6-10 years after surgery, the maximum bladder capacity and bladder compliance increased to 490.2% and 627.9% and the maximum detrusor pressure decreased to 25.8% of the preoperative level. The UUTD of the patients was significantly reduced after surgery. The number of the high grade UUTD decreased to 116 (116/398, 29.2%) at 1-3 months and 51 (51/274, 18.6%) at 4-6 months. At 6-10 years, the number of the high-grade UUTD decreased to 4 (4/76, 5.3%) ( P<0.001), which was significantly lower than that before operation. The VUR was significantly relieved after operation, and 393 ureters had no VUR at 1-3 months, accounting for 97.8% (393/402) of the total ureters. Sustained remission of VUR was observed during follow-up. 73 ureters had no VUR at 6-10 years, accounting for 96.1% (73/76) of total ureters ( P<0.001). Patients' creatinine decreased to 79.0 (65.0-128.2) μmol/L at 1-3 months postoperatively, with a downward trend but no statistical difference, and creatinine levels were not significantly elevated at any postoperative time point compared with preoperative levels ( P>0.05). Postoperative complications included metabolic acidosis in 26 cases (9.9%), vesicoureteral anastomosis stenosis in 15 cases (5.7%), recurrent urinary tract infection in 16 cases (6.1%), and urinary calculi in 20 cases (7.6%), and intestinal obstruction requiring laparotomy in 8 cases (3.1%), all of them could be improved after treatments. Conclusions:AUEC is a safe and effective method for treating high-grade VUR or VUR with impaired anti-reflux mechanism, high-grade UUTD or UUTD with ureteral or vesicoureteral junction obstruction, and all of the complications can be improved after treatment. This technique can increase the bladder capacity and compliance, reconstruct the anti-reflux mechanism, and release upper urinary tract obstruction. It may play an important role in stabilizing and protecting the residual renal function from further deterioration.

Objective To investigate the prevalence and influencing factors of HIV/AIDS patients with hyperlipidemia before and after receiving antiviral therapy in Wuhan. Methods A retrospective cohort study was used to analyze the data of HIV/AIDS patients in Wuhan from 2004 to 2021. Elevated levels of either TG or TC were determined as hyperlipidemia. Logistic regression model was used to analyze the influencing factors of baseline hyperlipidemia, and Cox proportional risk model was used to analyze the influencing factors of new-onset hyperlipidemia after receiving antiviral therapy. Results A total of 7 562 HIV/AIDS patients were enrolled, 30.61% (2 315/7 562) with hyperlipidemia at baseline and 69.39% (5 247/7 562) without hyperlipidemia. The mean person-years of follow-up for those patients without hyperlipidemia at baseline were 3.48, of whom 33.14% (1 739/5 247) developed hyperlipidemia during follow-up, with an overall density of 9.53/100 person-years. Multivariate logistic regression analysis showed that age ≥30 years and BMI ≥24 kg/m² were positively correlated with baseline hyperlipidemia, while CD4 cell count ≥ 200 μL was negatively correlated with baseline hyperlipidemia. Multivariate Cox model analysis showed that new-onset hyperlipidemia after receiving antiviral therapy was significantly positively correlated with BMI between 18.5-23.9 and ≥24 kg/m², the initial antiviral treatment regimen containing LPV/r, efavirenz and other factors A baseline CD4 cell count of 200 to 349 cells /μL was negatively correlated with new-onset hyperlipidemia. Conclusion HIV/AIDS patients with high BMI and an initial antiviral regimen including Kaletra or efavirenz have a significantly higher risk of hyperlipidemia. Follow-up monitoring of blood lipid in these patients should be strengthened.
