Objective:To investigate the surgical efficacy and prognosis influencing factors of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment.Methods:The retrospective cohort study was conducted. The clinicopathological data of 91 patients with hilar cholangiocarcinoma who underwent surgery in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from April 2004 to April 2021 were collected. There were 59 males and 32 females, aged (61±10)years. Patients who were admitted from April 2004 to March 2014 underwent traditional surgical diagnosis and treatment, and patients who were admitted from April 2014 to April 2021 underwent multidisciplinary diagnosis and treatment. Observation indica-tors: (1) surgical situations; (2) postoperative situations; (3) postoperative pathological examina-tions; (4) postoperative prognosis analysis; (5) influencing factors of postoperative prognosis. Follow-up was conducted using telephone interview and outpatient examination. Patients were followed up once every 6 months after surgery to detect survival. The follow-up was up to April 2023. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Comparison of ordinal data was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Kaplan-Meier method was used to draw survival curve and calculate survival rate. The Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard model. Results:(1) Surgical situations. Of the 91 patients, there were 65 cases receiving hemi- or expanded hemi-hepatectomy, 13 cases receiving tri-hepatectomy, 9 cases receiving partial hepatectomy, 4 cases receiving extrahepatic bile duct resection. There were 24 cases receiving combined vein resection and reconstruction, 8 cases receiving combined pancreaticoduodenectomy, 6 cases receiving com-bined hepatic artery resection and reconstruction, including 24 cases receiving extended radical surgery (tri-hepatectomy, hepatic artery resection and reconstruction, hepatopancreaticoduodenec-tomy). The operation time, volume of intraoperative blood loss and intraoperative blood transfusion rate of 91 patients was (590±124)minutes, 800(range, 500?1 200)mL and 75.8%(69/91), respectively. Of the 91 patients, cases receiving extended radical surgery, the volume of intraoperative blood loss were 4, 650(range, 300?1 000)mL in the 31 patients who were admitted from April 2004 to March 2014, versus 20, 875 (range, 500?1 375)mL in the 60 patients who were admitted from April 2014 to April 2021, showing significant differences between them ( χ2=4.39, Z=0.31, P<0.05). (2) Post-operative situations. The postoperative duration of hospital stay and cases with postoperative infectious complications were (27±17)days and 50 in the 91 patients. Cases with abdominal infection, cases with infection of incision, cases with bacteremia and cases with pulmonary infection were 43, 7, 5, 8 in the 91 patients. One patient might have multiple infectious complications. Cases with bile leakage, cases with delayed gastric emptying, cases with chylous leakage, cases with liver failure, cases with pancreatic fistula, cases with intraperitoneal hemorrhage, cases with reoperation, cases dead during the postoperative 90 days were 30, 9, 9, 6, 5, 3, 6, 3 in the 91 patients. Cases with abdominal infection was 10 in the 31 patients who were admitted from April 2004 to March 2014, versus 33 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=4.24, P<0.05). Cases dead during the postoperative 90 days was 3 in the 31 patients who were admitted from April 2004 to March 2014, versus 0 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( P<0.05). (3) Post-operative pathological examinations. Of the 91 patients, cases with Bismuth type as type Ⅰ?Ⅱ, type Ⅲ, type Ⅳ, cases with T staging as Tis stage, T1 stage, T2a?2b stage, T3 stage, T4 stage, cases with N staging as N0 stage, N1 stage, N2 stage, cases with M staging as M0 stage, M1 stage, cases with TNM staging as 0 stage, Ⅰ stage, Ⅱ stage, Ⅲ stage, ⅣA stage, ⅣB stage, cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 46, 30, 1, 9, 25, 30, 26, 49, 36, 6, 85, 6, 1, 7, 13, 58, 6, 6, 63, 28. Cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 16 in the 31 patients who were admitted from April 2004 to March 2014, versus 48, 12 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=9.59, P<0.05). (4) Postoperative prognosis analysis. Of the 91 patients, 3 cases who died within 90 days after surgery were excluded, and the 5-year overall survival rate and median overall survival time of the rest of 88 cases were 44.7% and 55 months. The 5-year overall survival rate was 33.5% in the 28 patients who were admitted from April 2004 to March 2014, versus 50.4% in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=5.31, P<0.05). Results of further analysis showed that the corresponding 5-year overall survival rate of cases without lymph node metastasis was 43.8% in the 16 patients who were admitted from April 2004 to March 2014, versus 61.6% in the 31 patients who were admitted from April 2014 to April 2021. There was a significant difference in the 5-year overall survival rate between these patients without lymph node metastasis ( χ2=3.98, P<0.05). The corresponding 5-year overall survival rate of cases with lymph node metastasis was 18.5% in the 12 patients who were admitted from April 2004 to March 2014, versus 37.7% in the 29 patients who were admitted from April 2014 to April 2021. There was no significant difference in the 5-year overall survival rate between these patients with lymph node metastasis ( χ2=2.25, P>0.05). (5) Influencing factors of postoperative prognosis. Results of multivariate analysis showed that poorly differentiated tumor and R 1 or R 2 resection were inde-pendent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma ( hazard ratio=2.62, 2.71, 95% confidence interval as 1.30?5.29, 1.30?5.69, P<0.05). Conclusions:Compared with traditional surgical diagnosis and treatment, treatment of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment can expand surgical indications, reduce proportion of dead patients within 90 days after surgery, improve proportation of radical resection and long-term survival rate. Poorly differentiated tumor and R 1 or R 2 resection are independent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma.

OBJECTIVE: To investigate the effect of Yinlai Decoction (YD) on the microstructure of colon, and activity of D-lactic acid (DLA) and diamine oxidase (DAO) in serum of pneumonia mice model fed with high-calorie and high-protein diet (HCD). METHODS: Sixty male Kunming mice were randomly divided into 6 groups by the random number table method: normal control, pneumonia, HCD, HCD with pneumonia (HCD-P), YD (229.2 mg/mL), and dexamethasone (15.63 mg/mL) groups, with 10 in each group. HCD mice were fed with 52% milk solution by gavage. Pneumonia mice was modeled with lipopolysaccharide inhalation and was fed by gavage with either the corresponding therapeutic drugs or saline water, twice daily, for 3 days. After hematoxylin-eosin staining, the changes in the colon structure were observed under light microscopy and transmission electron microscope, respectively. Enzyme-linked immunosorbent assay was used to detect the protein levels of DLA and DAO in the serum of mice. RESULTS: The colonic mucosal structure and ultrastructure of mice in the normal control group were clear and intact. The colonic mucosal goblet cells in the pneumonia group tended to increase, and the size of the microvilli varied. In the HCD-P group, the mucosal goblet cells showed a marked increase in size with increased secretory activity. Loose mucosal epithelial connections were also observed, as shown by widened intercellular gaps with short sparse microvilli. These pathological changes of intestinal mucosa were significantly reduced in mouse models with YD treatment, while there was no significant improvement after dexamethasone treatment. The serum DLA level was significantly higher in the pneumonia, HCD, and HCD-P groups as compared with the normal control group (P<0.05). Serum DLA was significantly lower in the YD group than HCD-P group (P<0.05). Moreover, serum DLA level significantly increased in the dexamethasone group as compared with the YD group (P<0.01). There was no statistical significance in the serum level of DAO among groups (P>0.05). CONCLUSIONS YD can protect function of intestinal mucosa by improving the tissue morphology of intestinal mucosa and maintaining integrity of cell connections and microvilli structure, thereby reducing permeability of intestinal mucosa to regulate the serum levels of DLA in mice.

Objective:To compare the clinical efficacy of the Simultaneous three scopes combined surgery [laparoscopic cholecystectomy(LC)+ choledochoscopy exploration + choledochectomy and removal of the common bile duct + primary suture of the common bile duct + endoscopic guided nasobiliary duct placement] and staged two scopes surgery[endoscopic retrograde cholangiopancreatography (ERCP) combined with LC] in the treatment of choledocholithiasis and cholecystolithiasis.Methods:From January 2018 to June 2020, we retrospectively analyzed the clinical data of 83 patients with choledocholithiasis and choledocholithiasis, who underwent minimally invasive treatment in our center. According to the different surgical procedures, the patients were divided into three-mirror group ( n=42) and two-mirror group ( n=41). All patients in the three-mirror group underwent three-scopy combined surgery. The patients in two-mirror group received endoscopic retrograde cholangiopancreatography (ERCP) combined with laparoscopic cholecystectomy (LC). In this study we compared the relevant clinical indicators of the two groups, in terms of the operation time, intraoperative blood loss, one-time stone clearance rate, postoperative exhaust time, postoperative defecation time, total hospitalization cost, incidence of postoperative acute pancreatitis, postoperative stone recurrence rate, incidence of postoperative cholangitis, and incidence of postoperative biliary fistula, total hospitalization time, postoperative bile duct stricture rate. Use SPSS 26.0 software to statistically analyze various indexes such as intraoperative, postoperative, follow-up, etc. Normally distributed measurement data were described by the mean±standard deviation ( Mean± SD), the comparison between groups was by t test, and measurement data with skewed distribution were destribed as M( P25, P75), Pairwise comparisons were analyzed using nonparametric test. The comparison of count data between groups was by the chi-square test. Results:No death was observed in both two groups. The operation time, intraoperative blood loss, one-time stone clearance rate, postoperative exhaust time, and postoperative defecation time of the three-mirror groupwere (167.98±47.37) min, 50(50, 100) mL, 100%(42/42), (2.10±0.76) days, 3(3, 4) days, the two-mirror group were (143.80±34.47) min, 50(50, 50) mL, 85.4%(35/41), (1.53±0.99) days and 2(1, 3) days. Compared with the two groups, the three-mirror group was higher than the two-mirror group, and the difference was statistically significant ( P<0.05). The total hospitalization expenses, postoperative acute pancreatitis incidence, and postoperative calculus recurrence rate in the three-mirror group were (3.46±0.77) ten thousand yuan, 0(0/42), 2.38%(1/42), the two-mirror group were (4.22±1.50) ten thousand yuan, 9.8%(4/41), 19.5%(8/41). Compared with the two groups, the three-mirror group was lower than the two-mirror group, and the difference was statistically significant ( P<0.05). No postoperative cholangitis or biliary fistula occurred in the two groups. There was no statistically significant difference in the total hospital stay and incidence of postoperative bile duct stenosis between the two groups ( P>0.05). Conclusions:For choledocholithiasis combined with cholecystolithiasis patients, simultaneous three-scopes combined surgery and elective LC after ERCP are safe and effective, and each has its own advantages. It should be selected reasonably according to the patient′s condition and combined with the technical advantages of the treatment team.

OBJECTIVE: To evaluate the effects of a 48-week course of adefovir dipivoxil (ADV) plus Chinese medicine (CM) therapy, namely Tiaogan Jianpi Hexue () and Tiaogan Jiedu Huashi () fomulae, in hepatitis B e antigen (HBeAg)-positive Chinese patients. METHODS: A total of 605 HBeAg-positive Chinese CHB patients were screened and 590 eligible participants were randomly assigned to 2 groups in 1:1 ratio including experimental group (EG, received ADV plus CM) and control group (CG, received ADV plus CM-placebo) for 48 weeks. The major study outcomes were the rates of HBeAg and HBV-DNA loss on week 12, 24, 36, 48, respectively. Secondary endpoints including liver functions (enzymes and bilirubin readings) were evaluated every 4 weeks at the beginning of week 24, 36, and 48. Routine blood, urine, and stool analyses in addition to electrocardiogram and abdominal B scan were monitored as safety evaluations. Adverse events (AEs) were documented. RESULTS: The combination therapy demonstrated superior HBeAg loss at 48 weeks, without additional AEs. The full analysis population was 560 and 280 in each group. In the EG, population achieved HBeAg loss on week 12, 24, 36, and 48 were 25 (8.90%), 34 (12.14%), 52 (18.57%), and 83 (29.64%), respectively; the equivalent numbers in the CG were 20 (7.14%), 41 (14.64%), 54 (19.29%), and 50 (17.86%), respectively. There was a statistically significant difference between these group values on week 48 (P<0.01). No additional AEs were found in EG. Subgroup analysis suggested different outcomes among treatment patterns. CONCLUSION Combination of CM and ADV therapy demonstrated superior HBeAg clearance compared with ADV monotherapy. The finding indicates that this combination therapy may provide an improved therapeutic effect and safety profile (ChiCTR-TRC-11001263).

OBJECTIVE: To investigate the effects of excessive endoplasmic reticulum stress on lung ischemia/reperfusion (I/R) induced myocardial injury in mice. METHODS: Forty healthy SPF male C57BL/6J mice were divided into 4 groups randomly (=10):sham operation group (Sham group), lung I/R group (I/R group), endoplasmic reticulum stress (ERS) pathway agonist Tunicamycin group (TM) and ERS inhibitor 4-phenyl butyric acid group (4-PBA). The model of lung I/R injury was established by clamping the left hilum of lung for 30 min followed by 180 min of reperfusion. In sham group, only sternotomy was performed, the hilum of lung was not clamped, and the mice were mechanically ventilated for 210 min. In TM and 4-PBA groups, TM 1mg/kg and 4-PBA 400 mg/kg were injected intraperitoneally, respectively, at 30 min before establishment of the model. At 180 min of reperfusion, blood samples were collected from the orbit for determination of myocardial enzyme. The animals were then sacrificed, and hearts were removed for determination of light microscope, TUNEL, Caspase 3 enzymatic activity, real-time polymerase chain reaction and Western blot. RESULTS: Compared with sham group, the cardiomyocytes had obvious damage under light microscope, and the serum creatine kinase-MB (CK-MB) and lactic dehydrogenase (LDH) activities, apoptosis index and Caspase 3 enzymatic activity were increased significantly, the expressions of p-Jun N-terminalkinase(p-JNK), Caspase 12, CCAAT/enhancer-binding protein homologous protein (CHOP) and glucose regulated protein 78(GRP78) protein and mRNA were up-regulated in I/R, TM and 4-PBA groups (<0.01). Compared with I/R group, the cardiomyocytes damage was obvious under light microscope, and the serum CK-MB and LDH activities, apoptosis index and Caspase 3 enzymatic activity were increased significantly, the expressions of p-JNK, Caspase 12, CHOP and GRP78 protein and mRNA were up-regulated in group TM; while all above changes were relieved in group 4-PBA (<0.01). Compared with TM group, the cardiomyocytes damage was relieved under light microscope, and the serum CK-MB and LDH activities, apoptosis index and Caspase 3 enzymatic activity were decreased significantly, the expressions of p-JNK, Caspase 12,CHOP and GRP78 protein and mRNA were down-regulated in group 4-PBA. CONCLUSIONS The excessive endoplasmic reticulum stress participates in myocardial injury induced by lung ischemia/reperfusion (I/R) and inhibit excessive endoplasmic reticulum stress response can relieved myocardial injury.

Objective: To evaluate the impact of KIT D816 mutation on the salvage therapy in relapsed acute myeloid leukemia (AML) with t(8;21) translocation. Method: The characteristics of the first relapsed AML with t(8;21) translocation from 10 hospitals were retrospectively collected, complete remission (CR(2)) rate after one course salvage chemotherapy and the relationship between KIT mutation and CR(2) rate was analyzed. Results: 68 cases were enrolled in this study, and 30 cases (44.1%) achieved CR(2). All patients received KIT mutation detection, and KIT D816 mutation was identified in 26 cases. The KIT D816 positive group had significantly lower CR(2) compared with non-KIT D816 group (23.1% vs 57.1%, χ(2)=7.559, P=0.006), and patients with longer CR(1) duration achieved significantly higher CR(2) than those with CR(1) duration less than 12 months (74.1% vs 31.9%, χ(2)=9.192, P=0.002). KIT D816 mutation was tightly related to shorter CR(1) duration. No significant difference of 2 years post relapse survival was observed between KIT D816 mutation and non-KIT D816 mutation group. Conclusion: KIT D816 mutation at diagnosis was an adverse factor on the salvage therapy in relapsed AML with t(8;21) translocation, significantly related to shorter CR1 duration, and can be used for prediction of salvage therapy response. KIT D816 mutation could guide the decision-making of salvage therapy in relapsed AML with t(8;21) translocation.

OBJECTIVE:To provide reference for clarifying the pharmacodynamic material basis of anti-inflammation effect of Uygur medicine Hyssopus cuspidatus. METHODS:HPLC was conducted to establish the fingerprint of 8 extracts with different po-larities. Using macrophage RAW264.7 as object,the inhibitory effect of extracts with different polarities on inflammatory factor ni-tric oxide(NO),TNF-α and IL-6 in supernatant of cell culture medium was detected,the differences of anti-inflammatory activity in vitro were compared. Grey correlation analysis method was used to analyze the spectrum-effect relationship of peak area of common peaks and anti-inflammation activity. RESULTS:The fingerprint of 8 extracts with different polarities showed obvious differences. Anti-inflammation in vitro results suggested that 30% ethanol extract had the strongest inhibitory effect on inflammatory cytokines in vitro. There were 14 common peaks in the established HPLC fingerprints,the 5 common peaks that was closely related to the in-hibitory effect of inflammatory factors in vitro were peak 8,6,5,10,13,respectively;peak 8 was rosmarinic acid. CONCLUSIONS:The established fingerprint and its spectrum-effect relationship with anti-inflammation activity in vitro can provide certain reference for its pharmacodynanic material basis study.

To investigate the effects of dexmedetomidine (DEX) on hypoxia/reoxygenation (H/R) injury-induced cell apoptosis and caspase-12 expression, A549 cells were randomly divided into 4 groups: control group, DEX group, H/R group and DEX+H/R group. Cells of control and DEX groups were cultured in the normoxic incubator for 30 h. Cells of H/R and DEX+ H/R groups were incubated in the anoxic cultivation for 6 h, followed by normoxic culture for 24 h, and DEX (1 nmol/L) was added into the culture medium in DEX and DEX+H/R groups. Morphological changes were observed under the inverted microscope. Cell viability was detected by CCK-8. The apoptosis index (AI) of A549 cells was detected by TUNEL method. The activity of caspase-3 enzyme in cells was detected by using caspase-3 kit. The expressions of GRP78, caspase-12 protein and mRNA were determined by Western blot and RT-PCR respectively. Compared with control group, the morphological changes of the cultured cells were observed: some of the cell fusion occurred and the shape of the cells was multilateral; the cell viability was decreased significantly (P < 0.01), the number of apoptotic cells and the AI value, caspase-3 activity, and the expressions of GRP78, caspase-12 protein/mRNA were significantly increased (P < 0.01) in H/R group. While the administration of DEX alleviated the H/R injury-induced cell damage, obviously increased the cell viability (P < 0.01), significantly decreased the increment of apoptotic cells and the AI value induced by H/R injury (P < 0.01), and also dramatically decreased the H/R injury-induced high level of caspase-3 activity (P < 0.01) as well as high expression of caspase-12 protein and mRNA (P < 0.01). Taken together, the results suggest that DEX can effectively protect A549 cells from the H/R injury, which may be mediated by down-regulating the expression of caspase-12 and inhibiting cell apoptosis.
