Objective: To explore the learning curve of transurethral 450 nm blue light vaporization of the prostate (TUBVP) in a district hospital，in order to provide reference for clinicians who plan to perform TUBVP. Methods: The clinical data of 56 patients with benign prostatic hyperplasia (BPH) who received TUBVP performed by the same group of surgeons in Chang'an District Hospital during Jun. and Dec. 2023 were retrospectively analyzed. Cumulative sum (CUSUM) was used to fit the learning curve of ratio of volume to operating time (RVOT) of prostate volume /450 nm blue light. The learning curve was divided into different stages according to the inflection points，and the clinical data of patients operated at different stages were analyzed and compared. Results: The learning curve of TUBVP was 21 cases，including 1-21 cases in the learning stage，22-38 cases in the improvement stage and 39-56 cases in the maturity stage. With the increase of cases，the postoperative bladder irrigation time reduced \[40.00 (26.00，44.50) h vs. 23.00(20.50，34.00) h vs. 23.50(14.75，40.75) h\]，with statistical difference (P<0.05). The surgical efficiency increased \[(0.51±0.14) vs. (0.55±0.17) vs. (0.63±0.23)\]，while the reduction of hemoglobin \[(6.43±7.35) g/L vs. (5.65±10.91) g/L vs. (2.61±7.36) g/L\]，catheter indwelling time \[70.0 (66.0，106.0) h vs. 71.0 (66.0，89.0) h vs. 66.0 (58.5，78.5) h\]，and incidence of complications (9.5% vs. 5.9% vs. 0) in the three stages showed a gradually decreasing trend，but with no statistical significance (P>0.05). Conclusion: The learning curve of TUBVP is 21 cases. For clinicians in district hospitals，TUBVP is a worthy choice.

【Objective】 To investigate the application value of 450 nm blue laser vaporization in the treatment of benign prostatic hyperplasia (BPH) in district hospitals, so as to provide reference for the selection of BPH treatment methods in district-level hospitals. 【Methods】 The clinical data of 39 BPH patients who received surgical treatment in Chang’an Hospital during Jan.and Sep.2023 were retrospectively analyzed.The patients were divided into two groups, including 19 in blue laser group treated with 450 nm blue laser vaporization and 20 in the TURP group treated with transurethral resection of the prostate (TURP).The operation time, hemoglobin decline, postoperative bladder irrigation time, catheter indwelling time and adverse events were compared between the two groups. 【Results】 All operations were successfully completed.In the blue laser group, the operation time [(45.11±22.08) min vs.(81.25±29.37) min], postoperative bladder irrigation time [(34.05±9.41) h vs.(47.60±9.05) h] and the decrease of hemoglobin [(7.79± 5.86) g/L vs.(16.40±10.23) g/L] were significantly lower than those in the TURP group (P<0.05).There was 1 case of urinary retention in the blue laser group, and there was no significant difference in indwelling catheter time between the two groups (P>0.05). 【Conclusion】 The 450 nm blue laser vaporization of prostate has advantages of less blood loss, shorter operation time and shorter postoperative irrigation time.Therefore, it should be considered as a preferable option for BPH in primary hospitals.

Objective To investigate the distribution of the thalassemia genotypes and the characteristics of blood cell parameters in Changshou District,Chongqing.Methods Totally 4126 samples sent to our hospital were studied from June 2018 to March 2023.All samples were detected for thalassemia genotype and blood cells.The parameters of blood cells:redblood cell(RBC),hemoglobin(Hb),mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC),red blood cell distribution width CV(RDW-CV),red blood cell distribution width SD(RDW-SD)were detected.Gap polymerase chain reaction(Gap-PCR)combined with reverse dot blot hybridization were used to detect alpha and beta thalassemia genotype.The rate and distribution characteristics of thalassemia gene in Changshou district were analyzed.Results Among 4126 samples,408 cases of α and β thalassemia were detected,accounting for 9.89%.Among these,there were 255 α-thalassemia cases.-α3.7/αα was the most common genotype.Two cases of--αSEA/-α3.7 and one cases of--SEA/HKαα were also detected.There were 153 cases of β-thalassemia and CD17 accounted for the highest proportion.The date of MCV,MCH,MCHC in-α3.7/αα,--SEA/αα,-α4.2/αα and ααCS/αα groups was significantly difference compared with control group(P<0.05).Parameters of MCV and MCH in CD17,CD41-42 and Ivs-2-654 groups were lower than those in control group(P<0.05),while RBC,RDW-CV and RDW-SD were higher than those in control group,the difference was statistically significant.Conclusion The most common genotype in thalassemia were-α3.7/αα,--SEA/αα,-α4.2/αα,CD17,CD41-42 and Ivs-2-654 in Changshou District,Chongqing.The parameters of MCV,MCHC,MCH,Hb,RBC,RDW-CV and RDW-SD have important clinical significance for the screening of thalassemia.

Objective:To analyze the status quo and influencing factors of the equity,accessibility and sustainability of the development of medical insurance for urban and rural residents in 2021,and provide a reference for improving the management and service level of medical insurance.Methods:Firstly,the"evaluation index system of medical insurance for urban and rural residents"was constructed,and the total index of the development level of medical insurance and its three subsystem indexes of equity,accessibility and sustainability were calculated.Secondly,the Theil index was used to measure the level differences of the three major regions in the east,central and west,and the spatial auto-correlation was used to analyze the spatial agglomeration and heterogeneity distribution pattern of the total index.Finally,a geographic weighted regression model was constructed to analyze the main influencing factors.Results:There were provincial differences in the development level of medical insurance,which showed a decreasing trend from east to west in geography and a random distribution pattern in space.Policy factors,economic factors,population structure,medical resource allocation and education level had a significant impact on the development level of medical insurance.Conclusions:It is proposed to promote the fairness at multiple levels,enhance the accessibility in all directions and dynamically improve the sustainability,and further explore the policy suggestions to improve the management and service level and enhance the residents'sense of experience,sense of gain and sense of happiness.
