Objective To explore the correlation between air pollutants (PM2.5, NO2, and CO) and the mortality rate of HIV/AIDS patients in Wuhan. Methods The death data of HIV/AIDS patients from January 1, 2017, to December 31, 2019, and the daily average atmospheric pollutant concentration during the study period were collected. A time-stratified case-control study design was used to explore the correlation between atmospheric pollutant concentration and patient mortality. Results For every 10 µg/m³ increase in CO concentration within 0-4 days of cumulative lag, AIDS-related mortality in HIV/AIDS patients increased by 1.79% (95% CIs: 0.04, 3.56). There was no statistical correlation between PM₃ and NO₃ concentrations and mortality in patients with HI and AIDS. Conclusion CO is positively correlated with the risk of AIDS-related death in HIV/AIDS patients. This study can provide relevant epidemiological evidence for public health authorities to develop more effective prevention measures for HIV/AIDS patients.

Breast cancer has become the malignant tumor with the highest incidence rate. Although the emergence of new drugs has prolonged the overall survival of breast cancer patients， it still possesses a high recurrence and metastasis rate due to tumor heterogeneity and drug resistance. Glucose is the main source of energy metabolism for breast cancer cells， and the glucose metabolism of breast cancer cells is significantly different from that of normal breast cells. The high energy demand and rapid growth of breast cancer cells make their demand for glucose much higher than that of normal cells. Moreover， even under aerobic conditions， the glycolytic effect of breast cancer cells will be significantly enhanced to meet the high energy metabolism demand of breast cancer cells. The main reason for the enhanced glycolytic effect of breast cancer cells is the enhanced activity of glycolysis-related enzymes and regulatory factors， including pyruvate kinase， hexokinase， phosphofructokinase， lactate dehydrogenase， and glucose transporter protein. The metabolism process of glycolysis in breast cancer cells can be regulated by interfering with the activity of these enzymes and regulatory factors， thus inhibiting the proliferation of breast cancer， promoting apoptosis， and reversing drug resistance， invasion， and metastasis. Traditional Chinese medicine （TCM） has a long history of treating breast cancer and has made significant achievements in the aspects of anti-recurrence， metastasis， and drug resistance. In recent years， more and more research related to the intervention of aerobic glycolysis in breast cancer by TCM monomers， single-flavored TCM， and compounds has been conducted and has made great achievements. In addition， a large number of in vivo and in vitro experiments have shown that aerobic glycolysis is an important potential target for the treatment of breast cancer by TCM， but there is a lack of a comprehensive review and summary. On this basis， this paper elaborated on the roles of key targets in aerobic glycolysis and breast cancer and summarized the relevant studies on the treatment of breast cancer by intervention of glycolysis with TCM， with a view to providing new ideas for further research.

Objective:To investigate the effect of posterior nasal neurectomy（PNN） with pharyngeal neurectomy （PN） on chronic sinusitis with nasal polyps （CRSwNP）complicated with perennial allergic rhinitis （PAR）. Methods:83 patients with perennial allergic rhinitis combined with chronic group-wide sinusitis with nasal polyps who attended our hospital from July 2020 to July 2021 were selected. All patients underwent conventional functional endoscopic sinusitis surgery（FESS）+ nasal polypectomy. Patients were divided according to whether they underwent PNN+PN. 38 cases in the experimental group underwent FESS combined with PNN+PN; 44 cases in the control group underwent conventional FESS alone. All patients underwent the VAS, RQLQ, and MLK before treatment, and at 6 months and 1 year after surgery. Meanwhile, other relevant data were collected and the preoperative and postoperative follow-up data were collected and analyzed to assess the differences between the two groups. Results:The total postoperative follow-up period was 1 year. The recurrence rate of nasal polyps at 1 year postoperatively and the nasal congestion VAS score at 6 months postoperatively were not statistically significant in the two groups（P>0.05）. However, the patients in the experimental group had statistically significantly lower effusion and sneezing VAS scores, MLK endoscopy scores and RQLQ scores at 6 months and 1 year postoperatively, and nasal congestion VAS scores at 1 year postoperatively compared to the control group（P<0.05）. Conclusion:For patients with perennial AR complicated with CRSwNP, the combination of the PNN+PN in FESS can significantly improve the short-term curative effect, and PNN+PN is a safe and effective surgical treatment.

Objective:To compare the efficacies of 3D printed guide plate assisted positioning and C-arm X-ray machine fluoroscopic positioning for femoral tunnel reconstruction of medial patellofemoral ligament in treating recurrent patellofemoral dislocation.Methods:A retrospective cohort study was performed on the clinical data of 60 patients with recurrent patellar dislocation admitted to the First Affiliated Hospital of Kunming Medical University from January 2018 to December 2022. The patients included 29 males and 31 females, with age range of 14-40 years [(28.6±7.6)years]. The 3D printed guide plate was used to locate the femoral tunnel in 30 patients for medial patellofemoral ligament reconstruction (3D guide group), and C-arm X-ray machine was used for another 30 patients (conventional group). (1) CT data of the knee joint were collected before surgery and at 7 days after surgery. Mimics 19.0 software was introduced to measure the distance between the center of femoral tunnel and Sch?ttle point after surgery. (2) Knee Lysholm score and Kujala score were used to evaluate the knee function before and at 3, 6, 9 and 12 months after surgery. (3) At the same time points, Opti-Knee TM 3D knee kinematics analysis system was used to collect the forward and backward displacement, up and down displacement, internal and external displacement, internal and external flipping angle, internal and external rotation angle, and flexion and extension angle of the affected knee joint. The range of each freedom degree was calculated and 6 freedom degree items of 30 healthy people were subjected to knee kinematics analysis. Results:All patients were followed up for 12-15 months [(12.3±0.7)months]. (1) The distance between the center of femoral tunnel and Sch?ttle point in the 3D guide group was (5.5±2.3)mm, smaller than that in the conventional group [(7.6±2.5)mm] ( P<0.01). (2) The Lysholm score and Kujala score of the 3D guide group and conventional gruop gradually increased after surgery (all P<0.01). There were no significant differences in the Lysholm score or Kujala score between the 3D guide group and conventional gruop before surgery and at 12 months after surgery (all P>0.05). At 3, 6 and 9 months after surgery, the Lysholm score of the 3D guide group [(70.4±4.5)points, (86.4±3.1)points, (91.2±3.2)points] and Kujala score [(74.2±5.3)points, (80.9±3.5)points, (85.2±3.2)points] were higher than those of the conventional group [Lysholm score: (67.3±5.2)points, (81.8±2.5)points, (86.2±1.9)points; Kujala score: (69.8±5.2)points, (77.6±2.1)points, (82.7±2.6)points] ( P<0.05 or 0.01). (3) Before surgery, the forward and backward displacement in the 3D guide group and conventional group [(0.6±0.1)cm, (0.6±0.2)cm], up and down displacement [(0.5±0.1)cm, (0.6±0.0)cm], internal and external displacement [(0.7±0.1)cm, (0.6±0.2)cm], and flexion and extension angle [(50.6±10.3)°, (51.6±8.5)°] were less than those in the healthy controls [(1.6±0.3)cm, (1.7±0.5)cm, (1.0±0.4)cm, (63.2±5.1)°] (all P<0.05), while the internal and external flipping angle [(17.5±4.0)°, (17.1±3.8)°] and internal and external rotation angle [(17.9±1.9)°, (17.5±1.5)°] were greater than those in the healthy controls [(11.8±3.6)°, (15.8±4.9)°] (all P<0.05). At other time points, the results of front and back displacement, up and down displacement, internal and external displacement, internal and external rotation angle in the 3D guide group and conventional group were not significantly different compared with the healthy controls (all P>0.05). The flexion and extension angle in the 3D guide group and conventional gruop were smaller than those in the healthy controls at 3 months after surgery (all P<0.05). At 6 and 9 months after surgery, the flexion and extension angle in the conventional group [(55.0±3.7)°, (57.7±4.8)°] were smaller than those in the healthy controls [(63.2±5.1)°, (63.2±5.1)°] (all P<0.05), but no significant difference was found between the 3D guide group [(61.0±4.8)°, (61.8±4.9)°] and the healthy controls (all P>0.05). The flexion and extension angle in the 3D guide group and conventional gruop was similar with that in the healthy controls at 12 months after surgery (all P>0.05). Conclusions:Compared with the C-arm X-ray machine, the 3D printed guide plate assisted positioning of femoral tunnel is more simple and accurate for the medial patellofemoral ligament reconstruction in treating recurrent patellofemoral dislocation, together with better early knee function recovery, better satisfaction of the patients, and better and faster restoration of the flexion and extension angle of knee joint kinematic function.

The aim of this study is to evaluate the efficacy of endoscopic surgery and conventional surgery combined with radiotherapy in the treatment of Neuroblastoma. Forty-three patients with olfactory neuroblastoma undergoing surgery combined with radiotherapy were retrospectively analyzed. The patients were divided into endoscopic surgery and conventional surgery. All patients received postoperative radiotherapy at a dose of 60-70 Gy, the 5-year survival rate and local recurrence time of the two groups were compared, and the therapeutic effects of endoscopic surgery and traditional surgery were compared. Through survival analysis, the 5-year overall survival rates of the traditional surgery group and the endoscopic surgery group were 50% and 58% （=0.560）, the local recurrence rates were 44% and 48% （=0.288）, and the mean recurrence time was 5.6 months and 12.5 months （=0.032）. There was no difference between endoscopic surgery and conventional surgery combined with radiotherapy in the treatment of Neuroblastoma, and the time of local recurrence was significantly prolonged. In early Neuroblastoma, endoscopic sinus surgery may be superior to open surgery in terms of efficacy and patient survival.

Objective:To compare death causes and the survival time in elderly patients undergoing hemodialysis versus peritoneal dialysis in the nephrology department of Beijing Hospital in the last 10 years.Methods:This was a retrospective study.Patients aged more than 60 years who had undergone dialysis and died in the dialysis center of Beijing Hospital between January 2010 and January 2019 were enrolled.A detailed medical history including gender, age, primary diseases, diabetes mellitus, time of dialysis initiation, time of death and direct cause of death were recorded.Results:A total of 153 elderly dialysis patients were enrolled, with a mean age of 76.6±7.7 years, a median dialysis vintage of 54.1(26.9, 86.4)months, including 83(54.2%)cases with diabetes.Patients were divided into the hemodialysis group(HD, n=114)and the peritoneal dialysis group(PD, n=39)according to the dialysis method.The mean ages of patients in the HD and PD groups were 77.1±7.9 and 75.0±7.0 years, and the median dialysis vintages were 56.5(27.4, 104.2)and 48.3(26.3, 66.6)months, respectively.The primary diseases of patients undergoing HD and PD were diabetic nephropathy(DN, 32.5% vs.48.7%), chronic glomerulonephritis(29.8% vs.17.9%)and hypertensive renal damage(21.1% vs.10.3%). The top three causes of mortality in patients undergoing HD and PD were cardiovascular diseases(32.4% vs.43.6%), infections(29.8% vs.28.2%)and cerebrovascular diseases(11.4% vs.15.4%). The compositions of primary diseases and death causes were similar between the two groups, with no significant difference.Kaplan-Meier curves indicated that the survival time of dialysis patients with diabetes mellitus was shorter than that of patients without diabetes mellitus(chi-square value was 12.829, P<0.001), and the survival time of HD patients was longer than that of PD patients(chi-square value was 8.161, P=0.004). In patients without diabetes mellitus, the survival time of HD patients was longer than that of PD patients( Z=-2.716, P=0.007). In patients with diabetes mellitus, HD and PD had similar survival outcomes( Z=-0.581, P=0.561). Conclusions:The proportion of patients with diabetic nephropathy is high in elderly dialysis patients.Cardiovascular and cerebrovascular diseases and infections are the main causes of death in elderly dialysis patients.The survival time is longer in HD patients than in PD patients.

Objective To analyze the causes of death of maintenance hemodialysis (MHD) patients,and to compare the long term survival rate between elderly patients and non-elderly patients and between diabetic nephropathy (DN) patients and non-DN patients at our hemodialysis center during last 20 years.Methods A total of 317 MHD patients were collected,and divided into elderly (≥60 years) and non-elderly (＜60 years) groups based on the age at starting hemodialysis.Besides,data of gender,primary diseases,and the direct cause of death in maintenance hemodialysis patients from 1996 to 2016 were collected.Results Cardiogenic diseases,infections,and cerebrovascular accidents were the three leading causes of death.The mean dialysis age was shorter in elderly MHD patients than in non-elderly MHD patients[(51.8 ± 45.7) months vs.(81.6 ± 66.5) months,t =4.271,P=0.000]with a lower survival rate (x2 =32.422,P =0.000).The mean dialysis age was significantly lower in DN patients than in non-DN patients[(44.1±33.8) months vs.(69.4±60.6) months,t=3.632,P =0.000)] with a lower survival rate (x2 =13.361,P =0.000).The overall survival rate was 59.8％ after the fifth year of MHD,was 33.3％ after the 10th year,was 8.4％ after the 20th year,in our dialysis center.Conclusions The long-term survival rate of patients receiving maintenance hemodialysis in our center is as high as that in the developed countries and in other hospitals in Beijing.The top three death causes are cardiac diseases,infections,and cerebrovascular accidents.For old or DN patients,the overall prognosis is poor.

Objective To investigate the clinical characteristics and laboratory examinations in incident dialysis effect on the prognosis of elderly patients undergoing hemodialysis.Methods Ninety-three patients aged 65 years or older initiating hemodialysis were enrolled from Hemadialysis Center of Beijing Hospital from January lst,2007 to June 30th,2016.The duration time of HD of all patients was more than three months.Patients were divided into death group and non-death group.The clinical characteristics and laboratory examinations were compared between the two groups.Cox proportional hazards regression was used for the multivariate analysis to determine independent prognosis factors.Results The average year of patients was 74.2±6.5 years old with 43 months of median time of follow-up.The first two causes of death were infection (n =25,49.0％) and cardiovascular and cerebrovascular diseases (n =16,31.4％).Cox single factor regression analysis showed that the older ages,diabetic nephropathy being the cause of end-stage renal disease (ESRD),complicating with diabetes mellitus or congestive heart failure,the higher Charlson cardiovascular diseases score,ALB being under 35 g/L were correlated with poor outcome respectively(P＜0.05).Cox multivariate regression analysis indicated that older ages (HR =1.056,P =0.021),diabetic nephropathy being the cause of ESRD (HR =2.661,P =0.001),the higher Charlson cardiovascular diseases score (HR =1.675,P =0.010),central venous catheters being vascular access(HR=1.167,P=0.048) on incident dialysis were the main risk factors for mortality in elderly patients.Conclusion The older ages,diabetic nephropathy being the cause of ESRD,the higher Charlson cardiovascular diseases score,central venous catheters being vascular access on incident dialysis are independent risk factors influencing survival of elderly patients.

The clinical data of 143 patients with type Ⅱ a hepatolithiasis with normal function of the sphincter of Oddi were analyzed.The patients were divided into two groups at random.The data of the 2 groups of patients were compared on the operating time,hospitalization,rates of complication,residual stone rates and recurrence rates.The A group patients underwent laparoscopic video choledochoscopic hepaticocholangiolithotomy,T-tube drainage and choledochoscopic lithotomy.The B group patients underwent laparoscopic video hepatectomy and choledochoscopic lithotomy.For most of the patients in the A group,the treatment had the advantages of less trauma,less complications and quicker recovery.There was no significant differences in residual stone rates and recurrence rates between the two groups.As it was difficult to remove stones in the caudate lobes of Ⅱ a type patients in A group due to the sharp angle between the hepatic duct and bile ducts of the caudate lobe,individualized programs should be adopted according to the location of stones on individual patients.
