Objective To compare the benefits and drawbacks of primary patch expansion versus pericardial tube right ventricular-pulmonary artery connection in patients diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD). Methods A retrospective study was conducted on patients diagnosed with PA/VSD who underwent primary right ventricular-pulmonary artery connection surgery at our center between 2010 and 2020. Patients were categorized into two groups based on the type of right ventricular-pulmonary artery connection: a pericardial tube group and a patch expansion group. Clinical data and imaging findings were compared between the two groups. Results A total of 51 patients were included in the study, comprising 31 males and 20 females, with a median age of 12.57 (4.57, 49.67) months. The pericardial tube group included 19 patients with a median age of 17.17 (7.33, 49.67) months, while the patch expansion group consisted of 32 patients with a median age of 8.58 (3.57, 52.72) months. In both groups, the diameter of pulmonary artery, McGoon index, and Nakata index significantly increased after treatment (P<0.001). However, the pericardial tube group exhibited a longer extracorporeal circulation time (P<0.001). The reoperation rate was notably high, with 74.51% of patients requiring further surgical intervention, including 26 (81.25%) patients in the patch expansion group and 12 (63.16%) patients in the pericardial tube group. No statistical differences were observed in long-term cure rates or mortality between the two groups (P＞0.005). Conclusion In patients with PA/VSD, both patch expansion and pericardial tube right ventricular-pulmonary artery connection serve as effective initial palliative treatment strategies that promote pulmonary vessel development and provide a favorable foundation for subsequent radical operations. However, compared to the pericardial tube approach, the patch expansion technique is simpler to perform and preserves some intrinsic potential for pulmonary artery development, making it the preferred procedure.

PURPOSE: To methodically assess the effectiveness of augmentative plating (AP) and exchange nailing (EN) in managing nonunion following intramedullary nailing for long bone fractures of the lower extremity. METHODS: PubMed, EMBASE, Web of Science, and the Cochrane Library were searched to gather clinical studies regarding the use of AP and EN techniques in the treatment of nonunion following intramedullary nailing of lower extremity long bones. The search was conducted up until May 2023. The original studies underwent an independent assessment of their quality, a process conducted utilizing the Newcastle-Ottawa scale. Data were retrieved from these studies, and meta-analysis was executed utilizing Review Manager 5.3. RESULTS: This meta-analysis included 8 studies involving 661 participants, with 305 in the AP group and 356 in the EN group. The results of the meta-analysis demonstrated that the AP group exhibited a higher rate of union (odds ratio: 8.61, 95% confidence intervals (CI): 4.12 - 17.99, p < 0.001), shorter union time (standardized mean difference (SMD): -1.08, 95% CI: -1.79 - -0.37, p = 0.003), reduced duration of the surgical procedure (SMD: -0.56, 95% CI: -0.93 - -0.19, p = 0.003), less bleeding (SMD: -1.5, 95% CI: -2.81 - -0.18, p = 0.03), and a lower incidence of complications (relative risk: -0.17, 95% CI: -0.27 - -0.06, p = 0.001). In the subgroup analysis, the time for union in the AP group in nonisthmal and isthmal nonunion of lower extremity long bones was shorter compared to the EN group (nonisthmal SMD: -1.94, 95% CI: -3.28 - -0.61, p < 0.001; isthmal SMD: -1.08, 95% CI: -1.64 - -0.52, p = 0.002). CONCLUSION In the treatment of nonunion in diaphyseal fractures of the long bones in the lower extremity, the AP approach is superior to EN, both intraoperatively (with reduced duration of the surgical procedure and diminished blood loss) and postoperatively (with an elevated union rate, shorter union time, and lower incidence of complications). Specifically, in the management of nonunion of lower extremity long bones with non-isthmal and isthmal intramedullary nails, AP demonstrated shorter union time in comparison to EN.

ObjectiveTo investigate the genetic polymorphism and structure of 47 autosomal microhaplotypes in the Han population in Changshu City, Jiangsu Province, and to evaluate the forensic efficiencies and forensic parameters. MethodsThe DNA library of unrelated individual samples was prepared according to MHSeqTyper47 kit manual and sequenced on the MiSeq FGx platform. Microhaplotype genotyping and sequencing depth statistics were processed using MHTyper. The genetic information of samples was then evaluated. The fixation index and genetic distance between the Jiangsu Changshu population and the reference populations in the 1000 Genomes Project phase 3 (1KG) were calculated, and forensic parameters were evaluated. ResultsThe fixation index and genetic distance between the Han population in Changshu, Jiangsu, and the CHB (Han Chinese in Beijing, China) reference population in 1KG were the lowest. The effective allele number (A_e) of each locus is also the closest between the two populations. The combined matching probability (CMP) of the Changshu Han population is close to the 5 populations of the East Asian reference super-population in 1KG, which is 1.25×10^-36, and the combined probability of exclusion reached 0.999 999 999 964 1. ConclusionThis study reported the genetic polymorphism and allele frequency of 47 microhaplotypes in a Han population in Changshu City, Jiangsu Province. This information provides a data basis for 47 microhaplotypes in forensic applications. In addition, the polymorphism differences between the 1KG reference population and the Han population in Changshu, Jiangsu were compared, and the genetic structure of 47 microhaplotypes in the Han population in Changshu, Jiangsu was revealed. In general, the reference data of the East Asian super-population in 1KG is more in line with the genetic characteristics of Han population in Changshu, Jiangsu.

Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.

Objective To investigate the effect of plasma microRNA(miR)-93-5p on ovarian granulosa cell proliferation in patients with polycystic ovary syndrome(PCOS)and its possible mechanism.Methods A total of 120 PCOS patients of childbearing period who were treated at Jiaozuo People's Hospital from January 2022 to January 2023 were selected as the PCOS group,and 18 healthy women of childbearing period who were physically examined at the same hospital during the same period were selected as the control group.The age,body weight and height of the subjects in the two groups were recorded,and the body mass index(BMI)was calculated.Fasting venous blood was collected from the subjects during the follicular phase of the natural menstrual cycle or the progesterone-induced withdrawal bleeding phase,and serum levels of luteinizing hormone(LH),follicle-stimulating hormone(FSH),total testosterone(TT),anti-Mullerian hormone(AMH),aspartate aminotransferase(AST),alanine aminotransferase(ALT),fasting insulin(FINS),and fasting blood glucose(FBG)were measured by using the electrochemical method;and the homeostasis model assessment of insulin resistance(HOMA-IR)was calculated.Quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the expression level of miR-93-5p in plasma of patients in the two groups.Human ovarian granulosa cells(KGN cells)in logarithmic growth phase were cultured in 6-well plates with 3 × 105 cells per well,and they were randomly divided into the miR-93-5p mimics group,LY294002+miR-93-5p group,AZD5363+miR-93-5p group,negative control(NC)group,and blank control group.The KGN cells in the miR-93-5p group were transfected with miR-93-5p mimics;the KGN cells in the LY294002+miR-93-5p group were transfected with miR-93-5p mimics and treated with 50 mmol·L-1 LY294002 one hour before transfection;the KGN cells in the AZD5363+miR-93-5p group were transfected with miR-93-5p mimics and treated with 50 μmol·L-1 AZD5363 one hour before transfection;the KGN cells in the NC group were transfected with the negative control plasmids;and the KGN cells in the blank control group were not treated at all.The expression of miR-93-5p in the KGN cells in each group was detected by qRT-PCR,and the proliferation of the KGN cells in each group was detected by cell counting kit-8.Results There was no significant differences in age,FSH,ALT,and AST levels of patients between the PCOS group and the blank control group(P＞0.05).The BMI,TT,AMH,LH,FINS,FBG,and HOMA-IR of patients in the PCOS group were significantly higher than those in the blank control group(P＜0.05).The relative expression of miR-93-5p in plasma of patients in the PCOS group was significantly higher than that in the blank control group(t=-5.549,P＜0.001).miR-93-5p was moderately positively correlated with TT,FINS and HOMA-IR(r=0.434,0.622,0.586;P＜0.001)and was mildly positively correlated with FBG and LH(r=0.398,0.398;P＜0.001).The receiver operating characteristic curve showed that the optimal cut-off value for plasma miR-93-5p in diagnosing PCOS was 1.380,the area under the curve was 0.906(95％confidence interval:0.839-0.973,P＜0.001),the sensitivity was 0.858,the specificity was 0.833,and the Youden index was 0.691.The relative expression of miR-93-5p in the KGN cells in the miR-93-5p mimics group,LY294002+miR-93-5p group and AZD5363+miR-93-5p group was significantly higher than that in the blank control group and NC group(P＜0.05).After 24,48 and 72 hours of culture,the proliferation of the KGN cells in the miR-93-5p mimics group,LY294002+miR-93-5p group and AZD5363+miR-93-5p group was significantly higher than that in the blank control group and the NC group(P＜0.05);the proliferation of the KGN cells in the LY294002+miR-93-5p group and AZD5363+miR-93-5p group was significantly lower than that in the miR-93-5p mimics group(P＜0.05).Conclusion miR-93-5p in plasma is overexpressed in PCOS patients,and it may be involved in the occurrence and development of PCOS by mediating the proliferation of ovarian granulosa cells through the phosphoinositide 3 kinase/protein kinase B signaling pathway.The miR-93-5p level in plasma has a certain diagnostic value for PCOS.

Objective To explore the expression level of microRNA(miR)-320a-3p in peripheral blood in patients with polycystic ovary syndrome(PCOS)and its possible mechanism for regulating PCOS.Methods A total of 149 PCOS patients admitted to the Jiaozuo People's Hospital from July 2021 to July 2022 were selected as the research subjects(PCOS group),and 18 healthy volunteers with a regular menstrual cycle(28-35 d),no clinical or biochemical manifestations of hyperandrogenism,and no polycystic ovary changes detected by ultrasonography were selected as the control group.Clinical data of the subjects in the two groups were collected and compared.The expression level of miR-320a-3p in plasma of subjects in the two groups was detected by using the real-time quantitative polymerase chain reaction.The correlation between plasma miR-320a-3p expression and clinical indexes was evaluated by using the Pearson partial correlation analysis.The predictive value of miR-320a-3p for PCOS was analyzed by using the receiver operating characteristic curve.The relationship between miR-320a-3p and androgen receptor was evaluated by using the dual luciferase reporter gene assay.Results There was no significant difference in age,hip circumference,follicle stimulating hormone(FSH),prolactin(PRL),and high-density lipoprotein cholesterol(HDL-C)between the two groups(P＞0.05).The body mass index,waist circumference,total testosterone(TT),anti-Miillerian hormone(AMH),luteinizing hormone(LH),fasting insulin(FINS),fasting blood glucose(FBG),2-hour postprandial blood glucose(2 h BG),homeostasis model assessment of insulin resistance(HOMA-IR),total cholesterol,triglycerides(TG),and low-density lipoprotein cholesterol(LDL-C)of patients in the PCOS group were significantly higher than those in the control group,while the level of estradiol(E2)was significantly lower than that in the control group(P＜0.05).The relative expression level of miR-320a-3p in plasma of patients in the PCOS group was significantly lower than that in the control group(P＜0.05).The expression level of miR-320a-3p was moderately negatively correlated with TT(r=-0.594,P＜0.05)and slightly negatively correlated with waist circumference,FINS,2 h BG,HOMA-IR,and LDL-C(r=-0.293,-0.208,-0.227,-0.208,-0.208;P＜0.05),and showed no significant correlation with hip circumference,AMH,FSH,E2,PRL,FBG,TG,and HDL-C(r=-0.079,0.020,-0.042,0.089,0.005,-0.141,-0.116,0.059;P＞0.05).The area under the curve of miR-320a-3p for predicting PCOS was 0.968(95％confidence interval:0.922-1.000,P＜0.05),with a cut-off value of 0.515,a sensitivity of 0.917,a specificity of 0.789,and a Jordon index of 0.706.miR-320a-3p negatively regulated androgen receptors.Conclusion miR-320a-3p is abnormally low expressed in peripheral blood of PCOS patients and may participate in the occurrence and development of PCOS by negatively regulating androgen receptors to increase TT levels.It has high predictive value for diagnosing PCOS.

Objective To explore the clinical efficacies of different surgical methods for elderly patients with lumbar tuberculosis.Methods The clinical data of 289 elderly patients with lumbar tuberculosis admitted to Hebei Chest Hospital from August 2018 to August 2021 were retrospectively analyzed.According to surgical methods,the patients were divided into the posterior group(109 cases),the anterior and posterior combination group(81 cases),and the anterior group(99 cases).The time of bone graft and fusion,operation time,hospital stay,intraoperative blood loss,and complications of the three groups were collected and compared among the three groups.The spine Cobb angle was regularly determined,the correction degree was calculated;the levels of erythrocyte sedimentation rate(ESR),white blood cell count(WBC),and C-reactive protein(CRP)were collected and compared among the three groups;and the Frankel grading and visual analogue scale(VAS)scores of the three groups were compared.Results After a 2-year follow-up,there was no significant difference in the time of bone graft and fusion among the three groups(P>0.05),the anterior group had the shortest operation time,the posterior group had the shortest hospital stay,and the lowest intraoperative blood loss and incidence of complications,with statistically significant differences(P<0.05).The correction degree of the anterior and posterior combination group was better than that of the posterior group and the anterior group(P<0.05),and the Cobb angles after operation and at the last follow-up in the posterior group was better(P<0.05).The anterior and posterior combination group had better improvement effect on CRP and ESR at the last follow-up(P<0.05),the WBC level of the posterior group was lower(P<0.05).The proportions of patients in grade E of Frankel grading at the last follow-up in the three groups were higher than those after surgery(P<0.05);compared with the preoperative period,the VAS scores at the last follow-up of the three groups decreased(P<0.05),and the VAS score of the posterior group was lower(P<0.05).Conclusion The effects of anterior surgery,posterior surgery and anterior and posterior combined surgery in the treatment of elderly lumbar tuberculosis are good,and the approach method can be scientifically and reasonably formulated according to patients' physical condition to improve the clinical treatment effect.

Objective:To investigate the diagnostic method and value of echocardiography in screening right patent ductus arteriosus(PDA) of infants.Methods:This was a prospective study.Thirty-one infants with right PDA diagnosed by ultrasound and confirmed by prenatal ultrasonography, electronic computed tomography angiography, angiocardiography and/or surgery in Hebei Children′s Hospital from April 2014 to May 2022 were collected as research subjects, and the association of right ductus arteriosus with aortic arch anomalies and complex cardiac malformations were summarized. The diagnostic method and value of ultrasonic screening were summed up.Results:Of the 31 cases, 30 cases were correctly diagnosed by ultrasound and 1 case was misdiagnosed, who was a left aortic arch descending to the right, a crossover variation of the right and left pulmonary arteries, and a rightward displacement of the ductus arteriosus. Among these cases diagnosed correctly, 27 cases (including 24 cases with right aortic arch and 3 cases with left aortic arch) presented that ductus arteriosus was open and its ostium of pulmonary artery end was located in the proximal right pulmonary artery in views of parasternal short-axis view of great vessels at cardiac base with the combination of two dimensions and color Doppler flow imaging. Other 3 cases of right aortic arch were all single ventricle with transposition of the great artery. Due to the parallel relationship of the two great arteries, the standard parasternal short-axis view of great vessels could not be obtained, and the right ductus arteriosus was found in the high parasternal views.In all of the 27 cases with right aortic arch and right ductus arteriosus, high parasternal views showed that one end of the ductus arteriosus was connected to the right aortic arch isthmus and the other end was connected to the right pulmonary artery. In all of the 3 cases with left aortic arch and right ductus arteriosus, the high parasternal views showed that one end of the ductus arteriosus was connected to the right subclavian artery and the other end was connected to the right pulmonary artery. Among the 27 cases with right aortic arch, 16 cases were accompanied with mirror image branches, 9 cases of which had complex cardiac malformations; 10 cases were associated with aberrant left subclavian artery, 1 case of which had complex cardiac malformations; 1 case was with isolated left subclavian artery, and without complex cardiac malformations. All 3 cases of left aortic arch were accompanied with isolated right subclavian artery and none of them were associated with complex cardiac malformations. Clinical outcomes of 30 cases with right PDA: 14 cases underwent ductus arteriosus ligation due to thick ductus or other heart malformations. In other 16 cases, 4 cases were closed spontaneously, 9 cases had persistent small ductus arteriosus, and 3 cases were lost to follow-up.Conclusions:Right ductus arteriosus is mostly related to the right aortic arch, and those with mirror image branches are prone to complex cardiac malformations; cases of left aortic arch with right ductus arteriosus are tend to accompany isolated right subclavian artery. Ultrasound has an important application in the screening and diagnosis of right PDA.

Objective:To measure the partial parameters of the soft tissues of upper eyelid in young women with single eyelid in Shantou City, Guangdong Province, and to explore the asymmetry rate of the left and right palpebral fissure and its regularity.Methods:From March 2018 to July 2019, the Medical Cosmetology Center of the First Affiliated Hospital of Shantou University Medical College measured 108 young women with single eyelid, aged 18-35 years, with an average age of 24.6 years. Before operation, palpebral fissure width (PFW), palpebral fissure height (PFH), palpebral fissure inclination (PFI) and central eyebrow height (CEH) were measured. The resected intra-orbital septum fat pad during the procedure was weighed. Both direct measurement and the photo measurement were used to obtain the average value of the two sets of data for final analysis. We calculated out the incidence rate of asymmetry of each palpebral item.Results:The paired t-test showed that the mean value of PFW was (25.76±1.50) mm on the left and (26.04±1.55) mm on the right ( t=2.93); the mean value of PFH was (9.70±1.15) mm on the left and (9.49±1.05) mm on the right ( t=3.12); the mean value of PFI was (9.77±2.57)° on the left and (9.67±2.28)° on the right ( t=2.01); the mean value of CEH was (12.05±1.61) mm on the left and (12.32±1.69) mm on the right ( t=-2.66); the mean value of the weight of the intra-orbital septum fat pad was (0.20±0.11) g on the left and (0.22±0.12) g on the right ( t=2.29). There were significant differences between the two sets of data (all P<0.05). Conclusions:The asymmetric phenomenon of the upper eyelid is commonly found in Shantou young female undergraduates, in which the PFH in the left is higher than that in the left; the PFW, the CEH, the weight of the intra-orbital septum fat pad in the right more commonly found than that in the left.. This study provides a certain reference for the clinical evaluation of the operation.

Enhanced recovery after surgery (ERAS) measures have not been systematically applied in transurethral surgery for benign prostatic hyperplasia (BPH). This study was performed on patients with BPH who required surgical intervention. From July 2019 to June 2020, the ERAS program was applied to 248 patients, and the conventional program was applied to 238 patients. After 1 year of follow-up, the differences between the ERAS group and the conventional group were evaluated. The ERAS group had a shorter time of urinary catheterization compared with the conventional group (mean ± standard deviation [s.d.]: 1.0 ± 0.4 days vs 2.7 ± 0.8 days, P < 0.01), and the pain (mean ± s.d.) was significantly reduced through postoperative hospitalization days (PODs) 0-2 (POD 0: 1.7 ± 0.8 vs 2.4 ± 1.0, P < 0.01; POD 1: 1.6 ± 0.9 vs 3.5 ± 1.3, P < 0.01; POD 2: 1.2 ± 0.7 vs 3.0 ± 1.3, P < 0.01). No statistically significant difference was found in the rate of postoperative complications, such as postoperative bleeding (P = 0.79), urinary retention (P = 0.40), fever (P = 0.55), and readmission (P = 0.71). The hospitalization cost of the ERAS group was similar to that of the conventional group (mean ± s.d.: 16 927.8 ± 5808.1 Chinese Yuan [CNY] vs 17 044.1 ± 5830.7 CNY, P =0.85). The International Prostate Symptom Scores (IPSS) and quality of life (QoL) scores in the two groups were also similar when compared at 1 month, 3 months, 6 months, and 12 months after discharge. The ERAS program we conducted was safe, repeatable, and efficient. In conclusion, patients undergoing the ERAS program experienced less postoperative stress than those undergoing the conventional program.
