[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

OBJECTIVES: To explore the value of serum cystatin C (CysC) levels in evaluating renal prognosis in IgA nephropathy (IgAN) patients. METHODS: We retrospectively collected the clinical data of IgAN patients diagnosed by renal biopsy at Guangdong Provincial People's Hospital from January, 2014 to December, 2018. Based on baseline serum CysC levels, the patients were divided into high serum CysC (>1.03 mg/L) group and normal serum CysC (≤1.03 mg/L) group. The composite endpoint for poor renal prognosis was defined as ≥50% decline in estimated glomerular filtration rate (eGFR) and/or progression to end-stage renal disease (ESRD). Lasso regression, multivariate Cox regression and Kaplan-Meier survival analysis were used to identify the risk factors and compare renal survival rates between the two groups. Smooth curves fitting and threshold effect analysis were used to explore the relationship between serum CysC levels and the outcomes. A nomogram model was constructed and its predictive performance was evaluated using concordance index, calibration curve, receiver operating characteristic (ROC) curve and the area under curve (AUC). RESULTS: A total of 356 IgAN patients were enrolled, who were followed up for 4.65±0.93 years. The composite endpoint occurred in 74 patients. High serum CysC was identified as an independent risk factor for poor renal prognosis in IgAN (HR=2.142, 95% CI 1.222 to 3.755), and the patients with high serum CysC levels had a lower renal survival rate (Log-rank χ²=47.970, P<0.001). In patients with serum CysC below 2.12 mg/L, a higher CysC level was associated with an increased risk of poor renal prognosis (β=3.487, 95% CI: 2.561-4.413, P<0.001), while above this level, the increase of the risk was not significant (β=0.676, 95% CI: -0.642-1.995, P=0.315). The nomogram model based on serum CysC and 3 other independent risk factors demonstrated good internal validity with a concordance index of 0.873 (95% CI: 0.839-0.907) and an AUC of 0.909 (95% CI: 0.873-0.945). CONCLUSIONS Serum CysC levels are associated with renal prognosis in IgAN patients, and high serum CysC an independent risk factor for poor renal prognosis.

Objective:To explore the short-term effect of drug-coated balloon angioplasty (DCBA) and common plain old balloon angioplasty (POBA) in the isolated popliteal artery chronic total occlusion (CTO), and to analyze the factors affecting the postoperative primary patency rate.Methods:A retrospective cohort study approach was used in this study. A total of 42 isolated popliteal CTO patients admitted to the First Affiliated Hospital of Bengbu Medical University from January 2020 to June 2022 were divided into two groups according to their different balloons: 24 as POBA group and 18 as DCBA group. The primary patency rate of target lesions, the clinically-driven target lesion revascularization(CD-TLR) rate, amputation and toe amputation rate, and the improvement of ankle-brachial index (ABI) and Rutherford grade at 6 and 12 months after surgery were compared.Measurement data with normal distribution was expressed as xˉ± s and means between two groups were compared using independent samples t-test. The percentage of counting data was calculated, and the rate between groups was compared by χ2 test or Fisher's exact probability method. Kaplan-Meier survival curve method was used to plot the survival curves of primary patency rate and CD-TLR free rate at 12 months after surgery, and Log rank test was used to compare the differences between groups . Univariate log rank test and multivariate Cox regression was used to analyze the factors affecting the primary patency rate at 12 months in patients with isolated popliteal CTO. Results:12 months after surgery, 4 patients in the DCBA group experienced lumen restenosis or occlusion while 12 patients in the POBA group experienced lumen restenosis or occlusion. The cumulative primary patency rate of target lesions in the DCBA group was higher than that in the POBA group (Log-rank χ2=4.03, P=0.045). ABI in the DCBA group at 6 and 12 months was greater than that in the POBA group [(0.91±0.11) vs (0.83±0.09), (0.84±0.11) vs (0.70±0.12), t=2.40, P=0.021, t=3.64 and P=0.001].There were no significant difference in cumulative CD-TLR exemption, amputation and amputation at 12 months, and Rutherford grade at 6 and 12 months for both groups(all P>0.05). The results of univariate analysis showed that DCBA as surgical method, hypertension and coronary heart disease were the influencing factors of the primary patency rate after chronic occlusion of the isolated popliteal artery (all P<0.05). The results of multivariate Cox regression analysis indicated that DCBA as surgical method was a protective factor for primary patency at 12 months (odds ratio =0.31,95% confidence interval: 0.10~0.870., P=0.038), while hypertension was an independent risk factor( OR=5.63,95% confidence interval: 1.54~20.56, P=0.009). Conclusions:The cumulative primary patency rate of target lesions 12 months after isolated popliteal CTO was higher than that of POBA. DCBA as surgical method was a protective factor for primary patency rate 12 months in patients with isolated popliteal CTO, while hypertension was an independent risk factor.

Objective To investigate the correlation between pericarotid fat density(PFD)and carotid plaque CT vulnerability characteristics.Methods The clinical and imaging data of 78 patients were analyzed retrospectively.PFD and subcutaneous neck fat density(SNFD),as well as plaque density,degree of lumen stenosis,and maximum plaque thickness were measured on picture archiving and communication system(PACS),and PFD/SNFD ratio was calculated.The plaques were divided into 4 subgroups according to their composition,namely fatty plaque group,fibrous plaque group,calcified plaque group and mixed plaque group.The groups were divided into no/mild-to-moderate stenosis group and severe stenosis/complete occlusion group according to the degree of stenosis,and the differences between groups were compared for clinical indices,PFD,SNFD and PFD/SNFD ratio,respectively.Results The PFD/SNFD ratio[0.54(0.32,0.72)]in the fatty plaque group was lower than that in the calcified plaque group[0.74(0.56,0.96)],with a statistically significant difference(P=0.005).The PFD/SNFD ratio in the severe stenosis/complete occlusion group(0.51±0.29)was lower than that in the no/mild-to-moderate stenosis group(0.67±0.27)(P=0.001),and the PFD in the severe stenosis/complete occlusion group[-39.75(-61.13,-24.00)]was higher than that in the no/mild-to-moderate stenosis group[-61.75(-72.00,-45.38)](P＜0.001).Conclusion PFD,PFD/SNFD ratio are correlated with carotid plaque vulnerability.

Objective: To examine the impact of laser-assisted hatching (LAH) technique on perinatal outcomes in blastocyst culture of low-grade cleavage embryos, so as to provide insights into improving the utilization of low-grade cleavage embryos and embryo quality. Methods: A total of 369 single live births after transfer of thawed blastocysts following in vitro fertilization or intracytoplasmic sperm injection at Zhejiang Provincial People's Hospital were selected as subjects, and they were divided into 51 conventional culture blastocysts and 318 LAH blastocysts based on whether LAH was performed on day 4 of blastocyst culture. Gestational age, birth weight, birth defects and maternal perinatal information were collected, and the prevalence of premature birth, birth weight and birth defects were analyzed after propensity score matching (PSM). Results: After PSM, 98 matched cases were included in the study. There were no statistically significant differences in maternal age, body mass index, type of infertility and blastocyst age (P>0.05), indicating effective matching. The birth weight of offspring in the LAH group was lower than that in the conventional culture group [(3 261.08±432.24) g vs. (3 464.18±444.46) g; P<0.05]. Conclusion The birth weight of offspring can be reduced by using LAH during blastocyst culture of low-grade cleavage embryos.

The paper reported a patient under maintained hemodialysis for 11 years, with a large mass appeared in the right thigh after local injury. The mass was clinically considered as tumoral calcinosis combined with clinical, imaging and pathological findings. Several treatments such as enhancing dialysis adequacy, low calcium dialysate, calcimimetic agent, non-calcium- phosphorus binding agents, parathyroidectomy and intravenous infusion of sodium thiosulfate could not vanish the mass. Finally, the lump was surgically removed. The treatment of tumoral calcinosis in the hemodialysis patient can provide a instruction for similar situations in clinical practice.

The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.

Objective:To investigate the epidemiological characteristics of hospitalized children with respiratory syncytial virus (RSV)-associated acute lower respiratory tract infection (ALRTI), and to analyzed the risk factors for severe infection.Methods:The epidemiological and clinical data of hospitalized children with ALRTI and positive RSV test from Children′s Hospital of Fudan University from January 2013 to December 2018 were retrospectively analyzed.The hospitalized children from October 2016 to November 2017 were selected by random singular sequence and divided into severe infection group and non-severe infection group. The clinical data of the two groups were compared. Multivariate logistic regression analysis was used to analyze the risk factors of severe RSV-associated ALRTI.Results:A total of 34 192 hospitalized children were diagnosed with ALRTI, and 8 113(23.73%) children were positive for respiratory tract viruses, including 4 028(11.78%) children with RSV infection, which was higher than other common respiratory tract viruses. Among the 4 028 RSV-positive children, 2 550(63.31%) were under six months of age, 3 623(89.95%) were under two years of age. The detection rates of RSV in spring, summer, autumn and winter were 6.47%(553/8 551), 2.46%(176/7 161), 12.85%(1 042/8 111) and 21.77%(2 257/10 369), respectively. In 347 hospitalized children with RSV-associated ALRTI, 54 cases were severe cases. Multivariate logistic regression analysis showed that RSV-positive patients complicated with respiratory diseases ( Z=3.43), cardiovascular diseases ( Z=4.96), non-exclusive breast-feeding ( Z=-1.97) and premature birth ( Z=-1.98) were independent risk factors for severe RSV-associated ALRTI (all P<0.050). Conclusions:RSV is the most important and common viral pathogen in hospitalized children with ALRTI in Shanghai, and infants under six months of age are the most susceptible to RSV. RSV patients complicated with respiratory diseases, cardiovascular diseases, non-exclusive breast-feeding and premature birth are more likely to develope severe RSV-associated ALRTI.
