Objective:To explore the effectiveness and safety of pie-crusting the medial collateral ligament release (MCL) in treating posterior horn of medial meniscus (PHMM) tear in tight medial tibiofemoral compartment of knee joint.Methods:Thirty-two consecutive patients with PHMM tear in tight medial tibiofemoral compartment of knee joint were admitted to our department from January,2013 to December,2014.All patients were performed pie-crusting the MCL release at its tibial insertion with 18-gauge intravenous needle.All patients were evaluated by valgus stress test and bilateral valgus stress radiograph at postoperative 1st day,4th week and 12th week.Visual Analogue Scales (VAS),Lysholm scores,Tegner scores and International Knee Documentation Committee (IKDC) scores were recorded at the 1st,3th,6th month follow-up,then follow-up every 6 months.Results:The mean follow-up was 28 (24-36) months.All cases were negative in valgus stress test.MCL rupture,femoral fracture,articular cartilage lesion and neurovascular injury were not found at the last follow-up.The median medial joint space width of affected side and unaffected side for valgus stress radiographs were 6.8 mm and 4.3 mm (P＜0.05) at the 1st day,5.5 mm and 4.2 mm (P＜0.05) in the 4th week and 4.8 mm and 4.3 mm (P＞0.05) at the 12th week,respectively.VAS scores was changed from 4.5±1.5 preoperatively to 1.7±1.0 at the final follow-up (t=16.561,P＜0.05).Lysholm scores was changed from 52.3±5.8 preoperatively to 93.2±6.3 at the final followup (t=-41.353,P＜0.05).Tegner scores was changed from 4.1±1.1 preoperatively to 5.5±0.6 at the final follow-up (t=-18.792,P＜0.05).IKDC scores was changed from 54.5±6.2 preoperative to 93.8±4.5 at the final follow-up (t=-38.253,P＜0.05).Conclusion:Pie-crusting the medial collateral ligament release is a safe,minimal invasive and effective surgical option for posterior horn of medial meniscus tear in tight medial tibiofemoral compartment of knee joint.

Objective To investigate the effect and mechanism of colchicine on mouse liver cancer via Hippo sig-naling pathway.Methods The 6-week-old male C57BL/6J mice were randomly divided into 3 groups:diethylni-trosamine(DEN)/carbon tetrachloride(CCl4)/ethanol(C2H5OH)induced mouse liver cancer model and col-chicine(0.1 mg/kg)intervention were established in control group,model group and colchicine group.From week 1st to week 2nd,the model group and the colchicine group were intraperitoneally injected with 1.0％DEN once a week.From week 3rd to week 7th,20％CCl4 dissolved in olive oil solution(5 ml/kg)was intragastric ad-ministration twice a week.From week 8th to week 18th,20％CC14 dissolved in olive oil solution(6 ml/kg)was intragastric twice a week.The colchicine group was given continuous intragastric administration for 20 weeks.The control group was given the corresponding solvent.Liver index,alanine aminotransferase(ALT)and aspartate ami-notransferase(AST)serum biochemical indexes were detected.Western blot and immunofluorescence were used to detect the expression levels of MST1,pYAP,YAP,pTAZ and TAZ proteins in liver tissues of mice in each group.Results The liver surface of mice in the control group was smooth and soft,while the liver of mice in the model group was rough and hard with granular nodules.The above lesions were significantly improved in the colchicine group.HE staining showed that the liver lobular structure of mice in the control group was normal,while the liver lobular structure of mice in the model group was disordered,with a small amount of fat droplets,extensive tissue necrosis,inflammatory cell infiltration,and fat vacuoles.The degree of liver lesions of mice after colchicine inter-vention was significantly reduced.The results of immunofluorescence and Western blot showed that compared with the control group,the protein expression levels of pYAP and pTAZ in liver tissue of model group mice were signifi-cantly decreased,while the protein expression levels of MST1,YAP and TAZ increased.After colchicine interven-tion,the protein expression levels of MST1,pYAP and pTAZ were significantly up-regulated,while the protein ex-pression levels of YAP and TAZ were down-regulated.Conclusion The therapeutic effect of colchicine on mouse liver cancer may be related to its activated Hippo signaling pathway.

Objective:To evaluate whether early enteral nutrition could benefit patients with different degrees of shock by dynamic changes of intestinal biomarkers intestinal fatty acid-binding protein (I-FABP) and citrulline.Methods:(1) From February 2021 to February 2023, 133 target patients in the Intensive Care Unit of Suzhou Hospital Affiliated to Nanjing Medical University were enrolled. The observation period was 7 days after admission, and intestinal biomarkers were monitored three times: 24 hours after admission (D1), the third day after admission (D3), and the seventh day after admission (D7). (2) The enrolled patients were divided into two groups according to the dose of norepinephrine received within 48 hours after admission: safe dose group [receiving norepinephrine < 0.3 μg/(kg·min)] and hazardous dose group [receiving norepinephrine ≥0.3 μg/(kg·min)]. The safe dose group was given early enteral nutrition according to the guidelines, and the dangerous dose group was randomly (random number) given early enteral nutrition (EEN) and delayed enteral nutrition (DEN).(4)The dynamic changes of intestinal fatty acid binding protein and citrulline in three groups were observed; The differences of intestinal biomarkers at different time points of dangerous dose of EEN/DEN were compared. The survival time of EEN/DEN group within 28 days was recorded, and Kaplan-Meier survival curve was drawn. Univariate and multivariate regression analyses of 28-day mortality were performed for the included population.Results:(1) The baseline data, APACHEⅡ score, arterial blood lactic acid, AGI grade, feeding interruption, total feeding time within 7 days, and 28-day survival number were statistically different between safe dose EEN group and hazardous dose EEN group ( P < 0.05). Compared the baseline data of the dangerous dose EEN group and the dangerous dose DEN group, only the number of feeding interruptions was statistically different ( P < 0.05). (2) The trend of change in the safe dose EEN group was the same as that in the dangerous dose DEN group: I-FABP decreased significantly from D3 to D7 ( P < 0.05); Citrulline decreased from D1 to D3, but increased from D3 to D7 ( P < 0.05). In dangerous dose EEN group, I-FABP had no significant change during the monitoring period ( P > 0.05). Citrulline decreased significantly from D1 to D3 ( P < 0.05). The EEN/DEN ratio at dangerous dose was significantly different only for D7-I-FABP ( P < 0.05). Compared with the survival curve of EEN/DEN at risk dose, DEN could improve the early survival rate of critically ill patients at risk dose (Breslow test P = 0.0447). (4) Age( OR=1.069,95% CI: 1.002-1.140, P=0.044) was independent risk factor for 28-day death . BMI ( OR= 0.772, 95% CI: 0.604-0.987, P=0.039), no feeding interruption ( OR=0.044,95% CI: 0.004-0.455, P=0.009), total feeding time within 7 days ( OR=0.959, 95% CI: 0.923-0.997, P=0.036) were the protective factors. Conclusions:EEN at the safe dose and DEN at the dangerous dose can effectively reverse the necrosis of enterocyte and promote the recovery of enterocyte function. EEN is not a clear risk factor for death at 28 days, but it not only increases the incidence of feeding interruption, but also do not conduct the recovery of intestinal cell function from the perspective of intestinal biomarkers.

Objectives:To investigate the effect of cardiac rehabilitation exercise guided by cardiopulmonary exercise test on cardiopulmonary function, cardiopulmonary endurance and activities of daily living in patients who had coronary heart disease after percutaneous coronary intervention (PCI).Methods:Seventy patients who had coronary heart disease after PCI treated in the Wenzhou Central Hospital from July 2022 to May 2023 were enrolled perspectively (3 cases eventually dropped out of the study), and they were divided into the control group (33 cases) and the rehabilitation group (34 cases) by random number table method. The control group was given conventional medication after PCI, while the rehabilitation group was additionally provided with exercise rehabilitation for 12 weeks on the basis of the control group. The patient′s cardiopulmonary function indicators, cardiopulmonary endurance indicators and ability of daily living(ADL) score of the two groups were compared before and after treatment.Results:After treatment for 12 weeks, the cardiopulmonary function indicators left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left atrial inner diameter (LAD), left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), forced expiratory volume in the first second (FEV 1), ratio of FEV 1 to forced expiratory volume (FVC) (FEV 1/FVC), maximum ventilation quantity (MVV) in the rehabilitation group were obviously improved compared with the control group: (102.8 ± 14.4) ml vs. (114.8 ± 20.4) ml, (39.9 ± 13.7) ml vs. (48.4 ± 16.9) ml, (37.1 ± 3.4) mm vs. (38.9 ± 3.6) mm, (50.3 ± 3.6) mm vs. (52.5 ± 4.7) mm, (64.0 ± 6.8)% vs. (59.6 ± 6.5)%, (2.39 ± 0.38) L vs. (2.10 ± 0.26) L, (77.7 ± 4.0)% vs. (73.8 ± 4.3)%, (101.6 ± 18.7) L/min vs. (89.6 ± 11.1) L/min, there were statistical differences ( P<0.05). After treatment for 12 weeks, the cardiopulmonary endurance indicators peak oxygen uptake (VO 2peak), peak oxygen uptake per kilogram of body weight (VO 2peak/kg), anaerobic threshold (AT), peak metabolic equivalent (METspeak), maximum working load (MWL) in the rehabilitation group were obviously improved compared with the control group: (1 441.8 ± 251.9) ml/min vs. (1 272.5 ± 207.0) ml/min, (20.7 ± 3.6) ml/(min·kg) vs. (18.2 ± 2.5) ml/(min·kg), (1 346.8 ± 201.3) ml/min vs. (1 075.4 ± 176.7) ml/min, (5.9 ± 1.1) Met vs. (5.2 ± 0.7) Met, (107.3 ± 29.1) Watt vs. (88.4 ± 17.8)Watt, there were statistical differences ( P<0.05). After treatment for 12 weeks, the ADL scores in the rehabilitation group was higher than that in the control group: (90.9 ± 8.1) scores vs. (85.6 ± 11.6) scores, there was statistical difference ( P<0.05). Conclusions:Carrying out cardiac rehabilitation exercise guided by cardiopulmonary exercise test can significantly enhance the cardiopulmonary function, cardiopulmonary endurance and self-care ability in patients who had accepted PCI for coronary heart disease.
