Objective To observe the clinical efficacy of stage treatment withTiao He Ying Wei(regulating Ying-nutritional and Wei-defensive qi) needling in treating insomnia.Method A hundred insomnia patients presenting difficulty falling asleep were randomized into group A1 and B1, 50 cases each; 100 insomnia patients presenting difficulty maintaining sleep were randomized into group A2 and B2, 50 cases in each group; 100 insomnia patients presenting early-morning awakening were randomized into group A3 and B3, 50 cases each. Group A1, A2 and A3 were treated withTiao He Ying Wei needling, while group B1, B2 and B3 were treated with conventional medication. The Symptoms score and cerebral blood flow indicators were observed before and after the intervention.Result After the treatment, the symptoms scores were significantly changed in each group (P<0.05). The improvement of symptoms score in group A1 was superior to that in group B1 (P<0.05); the improvement of symptoms score in group A2 was superior to that in group B2 (P<0.05); the improvement of symptoms score in group A3 was superior to that in group B3 (P<0.05). The cerebral blood flow indicators (middle cerebral artery, posterior cerebral artery, anterior cerebral artery, and basilar artery) were significantly changed after the treatment in group A1, A2 and A3 (P<0.05). After the treatment, there were significant differences in comparing the cerebral blood flow indicators between group A1 and B1, A2 and B2, and A3 and B3 (P<0.05).Conclusion Stage treatment withTiao He Ying Wei needling can improve the sleep quality of insomnia patients.

Objective:To explore the epidemiological characteristics, clinical characteristics, treatment strategies and clinical results of non-dislocated hyperextension tibial plateau fracture.Methods:A total of 25 cases of non-dislocated hyperextension tibial plateau fracture patients were collected, including 12 males and 13 females, aged 27-79 years with an average age of 51±15 years. Causes of injury: 18 cases of traffic accident, 2 cases of heavy injury, 5 cases of falling injury. Schatzker classification of tibial plateau fracture: 4 cases of type II, 5 cases of type IV, 13 cases of type V, 3 cases of type VI. Three columns theoretical classification: 4 cases of simple lateral column, 5 cases of simple medial column, 7 cases of medial column+lateral columns, 9 cases of three columns. Preoperative tibial plateau posterior slope angle was -10-0 degrees, average-5.2 degrees. Preoperative MRI showed 5 cases of medial collateral ligament (MCL) injury, 3 cases of posterolateral complex (PLC) complex injury, 2 cases of PLC+ posterior cruciate ligament (PCL) injury and 10 cases of menisci injury. The change of tibial plateau posterior slope angle was more than 10 degrees in patients with ligament injury, 5 patients had a tibial plateau posterior slope angle change more than 15 degrees, 5 patients had a tibial plateau posterior slope angle change more than 10 degrees, and the patients with a tibial plateau posterior slope angle change less than 10 degrees had no ligament injury; 6 patients with simple lateral column or medial column fracture had a ligament injury, 2 patients with medial column+lateral column fracture had a ligament injury, and 2 patients with three column fracture had a ligament injury.Results:All patients were followed up for 12-24 months, with an average of 16.4 months. The operation time was 124±33 min (65-180 min), and the bleeding volume was 106±48 ml (20-200 ml). All patients were treated by open reduction and internal fixation. According to the characteristics of fracture, targeted reduction of articular surface and restoration of lower limb force line were carried out. The plate was placed on the anterior part of tibial plateau to fix the fracture fragment. Evaluation of postoperative fracture reduction: 20 cases were anatomic reduction, 5 cases were good reduction (between 2-5 mm articular surface collapse), and the excellent rate of fracture reduction was 100%. Internal fixation: 4 cases were treated with simple lateral plate, 2 cases with simple medial plate, 15 cases with medial+ lateral plate, 1 case with medial plate+ lateral anchor suture, 1 case with medial plate+ posterior screw, 1 case with lateral plate+ fibular screw, 1 case with medial plate + lateral plate+ lateral anchor suture. The meniscus was repaired in 8 patients, including 5 medial and 3 laterals. The fracture healing time was 3-6 months (mean 3.3 months). The postoperative knee Rasmussen score was 24.9±3.5 (18-29), and the postoperative knee joint mobility was 118°±9° (90°-130°). Superficial infection occurred in 2 patients.Conclusion:The main imaging characteristic of "non-dislocated hyperextension tibial plateau fracture" is the change of tibial plateau posterior slope angle. The injury of single anteromedial column/anterolateral column fracture is easy to combine with the "diagonal" injury, and when the tibial plateau posterior slope angle changes more than 10 degrees, it is easy to be associated with peripheral ligament injury. By using open reduction and internal fixation, restoring the joint articular surface and lower limb force line, repairing the soft tissue structure and ligament, and reconstructing the stability of knee joint, we can achieve satisfactory results.

Objective:To study the effect of diabetes mellitus (DM) on sepsis in patients with pyogenic liver abscess (PLA).Methods:The clinical data of 116 patients with PLA treated in the Affiliated Hospital of Jiangnan University from January 2021 to May 2022 were retrospectively analyzed, including 64 males and 52 females, aged (62.3±12.6) years old. Patients were divided into DM group ( n=56) and non-DM group ( n=60), which were also divided into the sepsis group ( n=29) and the non-sepsis group ( n=87). The clinical features were compared among the groups, the risk factors of PLA complicated with sepsis were analyzed by multivariate logistic regression. Mediation model was used to analyze how DM affects the development of sepsis. Results:Compared with the non-DM group, patients in DM group had higher incidences of hypertension and acute physiology and chronic health evaluation II, a higher proportion of blood neutrophil count, a higher serum levels of triglyceride, urea nitrogen, fasting blood glucose and glycated hemoglobin at admission. The DM group also higher incidences of hypoproteinemia, pleural effusion, and sepsis, with longer hospital stay and higher hospitalization cost (all P<0.05). The levels of hemoglobin, albumin and hematocrit were lower in DM group (all P<0.05). Multivariate logistic regression analysis showed that comorbidity of DM ( OR=3.431, 95% CI: 1.245-9.455) and abscess with a larger diameter ( OR=1.664, 95% CI: 1.258-2.220) were associated with a higher risk of developing sepsis (all P<0.05). Mediation model showed that neutrophil count and triglyceride were the mediating variables of sepsis in patients with PLA. Conclusion:Comorbidity of diabetes is an independent risk factor of developing sepsis in patients with pyogenic liver abscess. Diabetes may induce sepsis by affecting the neutrophils and triglyceride.

Background::Polycystic ovarian syndrome (PCOS) is a heterogeneous and complex reproductive endocrinological disease that could lead to infertility. There were many attempts to classify PCOS but it remains unclear whether there is a specific subgroup of PCOS that is associated with the best or worst reproductive outcomes of assisted reproductive techniques (ART).Methods::Infertile PCOS patients who underwent their first cycle of in vitro fertilization (IVF) in West China Second University Hospital, Sichuan University from January 2019 to December 2021 were included. Basic clinical and laboratory information of each individual were extracted. Unsupervised cluster analysis was performed. Controlled ovarian stimulation parameters and reproductive outcomes were collected and compared between the different clusters of PCOS. Results::Our analysis clustered women with PCOS into "reproductive", "metabolic", and "balanced" clusters based on nine traits. Reproductive group was characterized by high levels of testosterone (T), sex hormone-binding globulin (SHBG), follicular stimulation hormone (FSH), luteinizing hormone (LH), and anti-Müllerian hormone (AMH). Metabolic group was characterized by high levels of body mass index (BMI), fasting insulin, and fasting glucose. Balanced group was characterized by low levels of the aforementioned reproductive and metabolic parameters, except for SHBG. Compared with PCOS patients in reproductive and balanced clusters, those in metabolic cluster had lower rates of good quality day 3 embryo and blastocyst formation. Moreover, PCOS patients in the reproductive cluster had greater fresh embryo transfer (ET) cancelation rate and clinical pregnancy rate after fresh ET than metabolic cluster (odds ratio [OR] = 3.37, 95% confidence interval [CI]: 1.77-6.44, and OR = 6.19, 95% CI: 1.58-24.24, respectively). And compared with PCOS of metabolic cluster, PCOS of balanced cluster also had higher chance for fresh ET cancelation (OR = 2.83, 95% CI: 1.26-6.35).Conclusion::Our study suggested that PCOS patients in metabolic cluster may be associated with adverse reproductive outcomes and might need individualized treatment and careful monitoring before and during ART.

Sarcopenia and physical deconditioning are common complications in patients with liver cancer,which are frequently caused by insufficient physical activity and poor nutritional status,resulting in physical frailty and a significant impact on the patient's physical fitness.Notably,sarcopenia,frailty,and poor cardiopulmonary endurance have all been linked to higher mortality rates among patients with liver cancer.Exercise intervention significantly improves various health parameters in liver cancer patients,including metabolic syndrome,muscle wasting,cardiorespiratory endurance,health-related quality of life,and reduction in hepatic venous pressure gradient.However,the link between physical exercise and liver cancer is commonly overlooked.In this article,we will examine the impact of exercise on liver cancer and present the most recent evidence on the best types of exercise for various stages of liver cancer.This article also summarizes and discusses the molecular mechanisms that control metabolism and systemic immune function in tumors.In brief,physical exercise should be considered an important intervention in the prevention and treatment of liver cancer and its complications.

Objective:To study the logistic regression model and Chi-square automatic interaction detection decision tree model in the prediction of the recurrence of acute pancreatitis (AP).Methods:Clinical data of 364 patients with AP admitted to the Affiliated Hospital of Jiangnan University from June 2021 to June 2022 were retrospectively analyzed, including 219 males and 145 females, aged 53 (19-91) years. The patients were divided into the recurrence group ( n=63), those who experienced a second or more episodes of AP, and the initial group ( n=301), those who were diagnosed of AP for the first time. Univariate and multivariate logistic regression analyses were performed to identify the factors associated with recurrence of AP, and the decision tree model was used to analyze those factors. Receiver operating characteristic (ROC) curve were plotted to analyze the predictive performance of the two models. Results:Multivariate logistic regression analysis showed that age ( OR=0.969, 95% CI: 0.949-0.990, P=0.004), body mass index ( OR=1.142, 95% CI: 1.059-1.232, P=0.001), and hyperlipidemia ( OR=3.034, 95% CI: 1.543-5.964, P=0.001) were independent factors influencing the recurrence of AP. The accuracy of the model in predicting recurrence was 83.2% (303/364). The decision tree model showed that hyperlipidemia and body mass index were factors influencing the recurrence of AP, with an accuracy of 82.7% (301/364) in predicting recurrence. The area under the ROC curve was larger in the logistic regression model compared to that in the decision tree model (0.776 vs 0.730, Z=2.02, P=0.043). Conclusion:The logistic regression model and the Chi-square automatic interaction detection decision tree model can help predict the recurrence of AP. It is recommended to combine the two models to better guide clinical practice.

Objective To investigate the effect of compound betamethasone adjuvant on break-through pain after unicompartmental knee arthroplasty under sciatic nerve combined with femoral nerve block.Methods A total of 100 patients underwent unicondylar knee arthroplasty,32 males and 68 females,aged 55-75 years,BMI 18.5-35.0 kg/m2,ASA physical status Ⅰ-Ⅲ,were divided into three groups according to random number table method:no adjuvant group(group C,n=34),dexamethasone adjuvant group(group D,n=33)and compound betamethasone adjuvant group(group B,n=33).The patients in the three groups received sciatic nerve block and 0.4％ropivacaine 15 ml before anesthesia in-duction,then femoral nerve block,0.4％ropivacaine 15 ml in group C,0.4％ropivacaine 15 ml in group D(containing dexamethasone 5 mg),and 0.4％ropivacaine 15 ml in group B(containing compound beca-methasone 4 mg).The occurrence of breakthrough pain,the number of effective analgesic pump compres-sions,opioid dosage,and the number of remedial analgesia cases were recorded.The ground movement dis-tance was recorded 0-24 hours,24-48 hours,and 48-72 hours after operation.The sleep quality scores and adverse events were also recorded.Results Compared with group C,the incidence rate of breakthrough pain was lower(P＜0.05),the number of effective analgesia pump compressions,the dosage of opioid,and the sleep quality score on the first night after operation were significantly decreased in group B(P＜0.05).Compared with group D,the incidence rate of breakthrough pain and breakthrough pain score were lower(P＜0.05),the number of effective analgesia pump compressions,the dosage of opioid,and the sleep quality score on the 1 st night after operation were significantly decreased in group B(P＜0.05).There was no significant difference in the ground movement distance of in different time periods and inci-dence of adverse events among the three groups.Conclusion Compound betamethasone adjuvant can reduce the incidence of breakthrough pain after unicompartmental knee arthroplasty under sciatic nerve com-bined with femoral nerve block,provide perfect analgesic effect,reduce postoperative opioid consumption,and improve the sleep quality of patients on the first night after surgery.

Nucleos(t)ide analogues (NUC) can inhibit the replication of hepatitis B virus (HBV) and effectively treat chronic hepatitis B (CHB), but they cannot completely eradicate HBV and cannot prevent the progression to hepatitis B cirrhosis and liver cancer in the context of a low viral load. In recent years, traditional Chinese medicine has been widely used in the treatment of CHB. This article elaborates on the application and mechanism of traditional Chinese medicine in inhibiting HBV replication, reducing the content of HBeAg, and delaying the progression to hepatitis B cirrhosis, and it is proposed that traditional Chinese medicine can improve the therapeutic effect of NUC in the treatment of CHB.

Objective:Recently, increasing number of lung cancer patients benefit from immune-checkpoint inhibitors (ICIs). However, the data of Chinese small cell lung cancer (SCLC) patients is limited. This study aims to analyze the response and survival data of ICIs treatment in SCLC and to explore the predictive biomarkers.Methods:Forty-seven SCLC patients who received ICIs treatment from Peking University Cancer Hospital from May 2017 to September 2019 was recruited. Clinical characteristics including sex, age, smoking status, ICIs strategy, PD-L1 expression and therapeutic efficacy were collected to explore the clinical predictive biomarkers for SCLC ICIs treatment.Results:Among the 47 patients, 18 (38.3%) cases were partial repose (PR), 11 (23.4%) were stable disease (SD), 18 (38.3%) were progressive disease (PD), and the objective response rate (ORR) was 38.3%, disease control rate (DCR) was 61.7%, the median progression-free survival (PFS) was 5.3 months. ICIs monotherapy accounts for 27.7%, the ORR was 15.4%, DCR was 53.8%, median PFS was 2.7 months. Combined therapy accounts for 72.3%, the ORR was 47.1%, DCR was 64.7%, median PFS was 5.4 months. Fourteen (29.8%) patients received ICIs as the first line treatment, their ORR was 85.7%, DCR was 100%, median PFS was 9.1 month. The ORR was not related to the age, sex, body mass index (BMI), smoking status and programmed death-ligand 1 (PD-L1) expression ( P>0.05). The ORRs were higher in patients underwent PD-L1 monotherapy ( P=0.001), combined therapy ( P=0.002) and received ICIs as the first line treatment ( P<0.001). Log-rank analysis indicated that the PFS of female patients were 12.0 months, significantly longer than 4.4 months of male patients in ICIs treatment ( P=0.038). Patients who received PD-L1 monotherapy, combined treatment, or ICIs as the first line treatment had longer PFS than their counterparts, though no statistical significant was observed ( P>0.05). Cox multivariate analysis showed that, the gender was not an independent predictor for PFS in ICIs treatment ( HR=3.777, 95% CI=0.974~30.891, P=0.054). Conclusions:Immunotherapy is an effective treatment strategy for SCLC. Patients who receive combined ICIs treatment, first line ICIs treatment and PD-L1 treatment may get greater benefits. PD-L1 expression cannot predict the response and PFS in SCLC ICIs treatment.
