Objective To compare the prognostic differences between simple and complex segmentectomies. Methods We conducted a retrospective cohort analysis of patients with solid pulmonary nodules (≤2 cm) who underwent segmentectomy. Recurrence-free survival (RFS) and local recurrence rates were evaluated. Results We included57 patients undergoing complex segmentectomy and 53 patients undergoing simple segmentectomy. Among patients who did not receive adjuvant therapy, those in the complex group had a significantly lower five-year RFS than those in the simple group (69.86% vs. 85.97%, P=0.04). Furthermore, the local recurrence rate was significantly higher in the complex group (18.75% vs. 4.65%, P=0.003) than in the simple group. Conclusion For solid pulmonary nodules (≤2 cm), complex segmentectomy is associated with inferior local control and worse RFS than simple segmentectomy.

Objective To investigate the molecular mechanism of Huangjing Zanyu Capsule(HJZY),a new class-Ⅲ traditional Chinese medicine for the treatment of male infertility developed by Wang Qi,an academician of the Chinese Academy of Engineering,based on AMPK-mediated mitophagy in the treatment of oligoasthenospermia.Methods Acrolein(ACR)was used to treat GC-2spd(ts)mouse spermatocytes to establish a cell model of oligoasthenospermia.The optimal ACR concentration and exposure time for subsequent modeling were determined by CCK8 cell viability assay.After successful modeling,the cells were cultured in complete medium containing different concentrations of HJZY.Then,cell viability was assessed by CCK8 assay after 24 hours,and the subsequent treatment concentration was determined based on the cell viability.After the GC-2spd cells adhered to the wall,they were divided into a normal control(NC)group,a modeling group,and an ACR+HJZY treatment group.The effect of HJZY on mitophagy was observed by confocal fluorescence microscopy.The three groups of cells were transfected with siRNA-NC and siRNA-AMPK,respectively,and divided into six groups,including siRNA-NC+control,siRNA-NC+ACR,siRNA-NC+ACR+HJZY,siRNA-AMPK+control,siRNA-AMPK+ACR,and siRNA-AMPK+ACR+HJZY groups.Western blot was performed to validate the regulatory effect of HJZY on mitophagy-related proteins,such as p-AMPK,LC3B,P62,PINK1,Parkin,TBK1,and ULK1,which were all proteins mediated by AMPK.Results Through the cell viability assay,34 μmol/L was selected as the the modeling concentration of ACR,and 20 minutes was selected as the modeling time The treatment concentration of HJZY was 160 μmol/L.Confocal fluorescence microscopy showed that HJZY had,to a certain degree,a positive regulatory effect on the mitochondrial membrane potential of damaged spermatogenic cells.The mitochondrial membrane potential of the model group decreased significantly compared with that of the NC group.After exposure to treatment,the cell membrane potential of the ACR+HJZY treatment group increased compared with that of the model group,and the difference was statistically significant(P＜0.05).Western blot results showed that the expression levels of p-AMPK/AMPK and PINK1 proteins in the siRNA-NC+ACR group were significantly lower than those in the siRNA-NC+control group(P＜0.001).The level of Parkin protein in the siRNA-NC+ACR group was lower than that in the siRNA-NC+control group,but the difference was not statistically significant.After the administration of HJZY,the levels of these 3 proteins increased,and those in the siRNA-NC+ACR+HJZY group were higher than those in the siRNA-NC+ACR group(P＜0.001).The expression levels of LC3B,P62,TBK1,and ULK1 proteins in the siRNA-NC+ACR group were higher than those in the siRNA-NC+control group(P＜0.01),and those in the siRNA-NC+ACR+HJZY group were lower than those in the siRNA-NC+ACR group(P＜0.05).After transfection with the gene-silencing siRNA-AMPK,the expression levels of p-AMPK/AMPK,PINK1,and Parkin proteins in the siRNA-AMPK+ACR group were lower than those in the siRNA-AMPK+control group(P＜0.01).After the administration of HJZY,there was no significant difference in the levels of these three proteins between the siRNA-AMPK+ACR+HJZY group and the siRNA-AMPK+ACR group.The expression level of LC3B protein in the siRNA-AMPK+ACR+HJZY group was still lower than that in the siRNA-AMPK+ACR group(P＜0.01).There was no significant difference in the levels of P62,TBK1,and ULK1 proteins between the siRNA-AMPK+ACR+HJZY group and the siRNA-AMPK+ACR group.Compared with the siRNA-NC+control group,the siRNA-AMPK+control group showed significantly decreased expression levels of p-AMPK/AMPK,ULK1,and TBK1 proteins(P＜0.001),decreased expression of PINK1 protein(P＜0.05),and increased expression of P62 protein(P＜0.001).Compared with the siRNA-NC+ACR group,the siRNA-AMPK+ACR group showed decreased expression of TBK1 protein(P＜0.001),decreased expression of LC3B protein(P＜0.01),and decreased expression of ULK1 protein(P＜0.05).The expression levels of PINK1 and Parkin proteins in the siRNA-AMPK+ACR group were lower than those in the siRNA-NC+ACR group,but the difference was not statistically significant.Compared with the siRNA-NC+ACR+HJZY group,the siRNA-AMPK+ACR+HJZY group showed decreased expression of p-AMPK/AMPK,PINK1,and Parkin proteins(P＜0.05),decreased expression of LC3B protein(P＜0.01),and increased expression of P62 protein(P＜0.001).There was no significant difference in the levels of TBK1 and ULK1 proteins between the siRNA-AMPK+ACR+HJZY group and the siRNA-NC+ACR+HJZY group.Conclusion HJZY may exert its therapeutic effect on oligoasthenospermia by regulating AMPK-mediated mitophagy.

Objectives:To investigate the survival and tumor recurrence after en bloc spondylectomy of spinal tumor and analyze the risk factors of postoperative tumor recurrence.Methods:This is a retrospective case series study. Data of 101 patients undergoing en bloc spondylectomy of spinal tumors in the Musculoskeletal Tumor Center, Peking University People′s Hospital from December 2006 to June 2022 were analyzed. There were 58 males and 43 females, aged (38.2±15.8) years (range: 10 to 79 years) at the time of surgery; the follow-up time was(44.0±36.0) months (range: 12 to 171 months).Among them, there were 25 relapsed patients, with 7 females and 18 males; aged (34.8±16.3) years (range: 12 to 66 years) at the time of surgery. The types of tumors included 5 giant cell tumors of bone, 6 osteosarcomas, 1 chordoma, 5 chondrosarcomas, 1 undifferentiated sarcoma, 1 fibrosarcoma, 2 Ewing sarcomas, 3 metastases and 1 malignant giant cell tumor of bone. Survival analysis of overall and relapsed patients were performed using the Kaplan-Meier curves. A segmented regression model was used to fit the sequence of recurrence rate changes over time since admission and identify change points for further analysis on risk factors. Univariate and multivariate Logistic regression analysis were performed to assess risk factors associated with recurrence rate; results from multivariate regression analysis were presented using a forest plot.Results:The tumor recurrence rate after en bloc spondylectomy was 24.8% (25/101).The overall median recurrence-free survival after en bloc spondylectomy was 161 months (95% CI: 92 months to NA).The median recurrence-free survival of recurrent patients was 13 months (95% CI: 12 to 27 months).Regarding the classification based on tumor malignancy, and relapse-free survival of metastatic tumors was significantly shorter ( P=0.007); and among the surgical margin groups, relapse-free survival of R0 group was significantly better than the R1 and R2 groups ( P<0.01). According to the segmented regression model, the tumor recurrence rate for en bloc spondylectomy showed a significant downward trend over time, with relatively higher recurrence rates before 2009 and a relatively stable trend after 2014. The results of univariate analysis showed that surgical margin and time of admission were the influencing factors of patient recurrence. The results of multivariate analysis showed that the R1 resection( OR=13.453,95% CI:2.897 to 97.941, P=0.002) and R2 resection( OR=11.379,95% CI:2.658 to 79.429, P=0.003) were independent influencing factor affecting patient recurrence. Conclusions:The overall tumor recurrence rate after en bloc spondylectomy was high. The surgical margin of tumor resection is an independent risk factor affecting tumor recurrence. Specifically, R2 and R1 resections significantly increase the risk of tumor recurrence.

ObjectiveTo study the effect of Bushen Huoxuetang on the apoptosis and the expression of B-cell lymphoma （Bcl-2）-associated X protein （Bax）/ Bcl-2 and cleaved cysteine-containing aspartate proteolytic enzyme-3 （cleaved Caspase-3） in the nude mouse model of bone metastasis of breast cancer， and explore the mechanism of Bushen Huoxuetang in inhibiting bone destruction. MethodThirty BALB/c female nude mice were randomly assigned into blank group （n=6） and model group （n=24）. The suspension of 4T1 breast cancer cells was injected into the tibia of mouse right lower limb to establish model of bone metastasis of breast cancer. The successfully modeled nude mice were randomly assigned into model group， Bushen Huoxuetang group， zoledronic acid group， and combined drug group， with 6 mice in each group. Bushen Huoxuetang was administrated at a dose of 36.67 g·kg^-1， once a day， and zoledronic acid was administrated by subcutaneous injection at a dose of 100 μg·kg^-1， twice a week. The combined drug group was administrated with the same doses of Bushen Huoxuetang group by gavage and zoledronic acid by subcutaneous injection. The mice in the blank group and the model group were administrated with the same volume of distilled water by gavage for 14 days. On the next day at the end of drug administration， the mice were sacrificed by cervical dislocation. The general situation and weight changes of the mice were examined. The right lower limb was collected， and X-ray scanning and hematoxylin-eosin （HE） staining methods were used for observation of pathological changes in the bone. The terminal deoxynucleotidyl transferase dUTP nick-end labeling （TUNEL） was employed to detect the apoptosis of bone tissue in nude mice， and Western blot to determine the expression of Bax/Bcl-2 and cleaved Caspase-3 in the bone tissue. ResultCompared with the blank group， the modeling reduced the body weight （P<0.01） and increased the right lower limb weight of the nude mice （P<0.01）. Compared with the model group， Bushen Huoxuetang， zoledronic acid， and their combination increased the body weight （P<0.01） and decreased the right lower limb weight （P<0.01）. Compared with the blank group， the other groups showed obvious tumor cell atypia， deep nuclear staining， and clear bone metastasis， and the model group showed obvious osteolytic damage in right lower limb and loss of proximal tibia and knee joint. Compared with the model group， Bushen Huoxuetang， zoledronic acid， and their combination reduced the osteolytic lesions in the right lower limb and recovered part of the bone structure， demonstrating an inhibitory effect on bone destruction. The TUNEL assay showed that the model group had lower apoptosis rate of bone metastatic tumor cells than the blank group， Bushen Huoxuetang group， zoledronic acid group， and combined drug group （P<0.01）. Compared with the blank group， the modeling down-regulated the expression of Bax and cleaved Caspase-3 （P<0.01） and up-regulated the expression of Bcl-2 （P<0.01）. Compared with the model group， Bushen Huoxuetang， zoledronic acid， and their combination up-regulated the expression of Bax （P<0.01） and cleaved Caspase-3 （P<0.05， P<0.01） and down-regulated the expression of Bcl-2 （P<0.05， P<0.01）. ConclusionBushen Huoxuetang may inhibit bone destruction in the nude mouse model of bone metastasis of breast cancer by up-regulating the expression of Bax， down-regulating the expression of Bcl-2， activating cleaved Caspase-3， and further inducing apoptosis.

Objective:To investigate the influencing of preoperative biliary drainage on surgery-related complications after pancreaticoduodenectomy.Methods:The retrospective case-control study was conducted. The clinical data of 267 patients with periampullary space-occupying lesion who were admitted to Beijing Friendship Hospital of Capital Medical University from January 2016 to July 2020 were collected. There were 166 males and 101 females, aged 61 (range, 54?84)years. Observation indicators: (1) comparison of preoperative situations in patients with and without preoperative biliary drainage; (2) comparison of intraoperative and postoperative situations in patients with and without preoperative biliary drainage; (3) methods and efficacy of preoperative biliary drainage; (4) factors influencing surgery-related complications after pancreaticoduodenec-tomy. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(rang) or M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was conducted using the corresponding statistical methods based on data type. Multivariate analysis was conducted using the Logistic stepwise regression model. Results:(1) Comparison of preoperative situations in patients with and without preoperative biliary drainage. Of the 267 patients, there were 104 cases with preoperative biliary drainage and 163 cases without preoperative biliary drainage. Cases with malignant tumor, cases with borderline tumor, cases with chronic pancreatitis were 89, 13, 2 in patients with preoperative biliary drainage, versus 111, 41, 11 in patients without preoperative biliary drainage, showing significant differences in pathology type between them ( χ2=10.652, P<0.05). (2) Comparison of intraoperative and postoperative situations in patients with and without preoperative biliary drainage. There was no significant difference in operation time, volume of intra-operative blood loss, postoperative complications, grade B pancreatic fistula, grade C pancreatic fistula, biliary leakage, abdominal or gastrointestinal bleeding, incidence of abdominal infection, white blood cell count at postoperative day 1, white blood cell count at postoperative day 3, neutrophil-to-lymphocyte ratio at postoperative day 1, neutrophil-to-lymphocyte ratio at postoperative day 3, C-reactive protein-albumin ratio at postoperative day 1, C-reactive protein-albumin ratio at post-operative day 3, duration of hospital stay between the 104 patients with preoperative biliary drainage and the 163 patients without preoperative biliary drainage ( P>0.05). (3) Methods and efficacy of preoperative biliary drainage. Of the 104 patients with preoperative biliary drainage, there were 40 cases receiving endoscopic nasobiliary drainage with drainage time as (12±2)days, there were 38 cases receiving percutaneous transhepatic cholangial drainage with drainage time as (7±1)days, and there were 26 cases receiving endoscopic retrograde biliary drainage with drainage time as (19±2)days. The total bilirubin, direct bilirubin, aspartate transaminase, alanine aminotrans-ferase in 104 patients were (223±18)μmol/L, (134±11)μmol/L, (112±10)U/L, (160±16)U/L before biliary drainage and (144±13)μmol/L, (84±8)μmol/L, (79±8)U/L, (109±12)U/L after biliary drainage, showing significant differences in the above indicators ( t=3.544, 3.608, 2.523, 2.509, P<0.05). (4) Factors influencing surgery-related complications after pancreatocoduodenectomy. Results of multi-variate analysis showed that operation time was an independent factor influencing surgery-related complications after pancreaticoduodenectomy ( odds ratio=1.005, 95% confidence interval as 1.002?1.008, P<0.05). Conclusions:Preoperative biliary drainage does not increase the incidence of complications related to pancreaticoduodenectomy in patients with periampullary space-occupying lesion. Operation time is an independent factor influencing postoperative surgery-related complications.
