Objective To investigate the clinical efficacy of Pinggan Capsules(composed of six Chinese herbs,i.e.Gentianae Radix et Rhizoma,Prunellae Spica,Rehmanniae Radix,Gastrodiae Rhizoma,Gardeniae Fructus and Plantaginis Herba)in treating patients with hypertension complicated with anxiety and depression of liver-yang hyperactivity type,and to explore the related influencing factors of efficacy.Methods A total of 150 patients diagnosed as hypertension complicated with anxiety and depression of liver-yang hyperactivity type treated at Guangdong Second Traditional Chinese Medicine Hospital from January 2022 to January 2023 were enrolled.The patients were randomly divided into the trial group and the control group using a random number table,with 75 cases in each group.The control group received conventional medicine treatment(Amlodipine Besylate Tablets plus Losartan Potassium Tablets),while the trial group received Pinggan Capsules in addition to the conventional treatment.The treatment for the two groups lasted for 8 weeks.Before and after treatment,the changes in blood pressure,Self-Rating Anxiety Scale(SAS)scores,Self-Rating Depression Scale(SDS)scores,and scores of each domain of World Health Organization Quality of Life-BREF(WHO-QOL-BREF)were observed in the two groups.Antihypertensive efficacy,TCM syndrome efficacy,and drug safety in the two groups were evaluated,and the main factors influencing the efficacy of Pinggan Capsules were analyzed.Results(1)During the treatment period,6 cases dropped out from the trial group and 4 cases dropped out from the control group.A total of 140 patients completed the full course of treatment,including 69 in the trial group and 71 in the control group.(2)After 8 weeks of treatment,the total effective rate for antihypertensive efficacy in the trial group was 89.86%(62/69),significantly higher than that in the control group[64.79%(46/71)].The intergroup(tested by chi-square test)showed that the antihypertensive efficacy of the trial group was significantly superior to that of the control group(P＜0.05).(3)After 8 weeks of treatment,the total effective rate for TCM syndrome efficacy in the trial group was 92.75%(64/69),significantly higher than that in the control group[66.20%(47/71)].The intergroup(tested by chi-square test)showed that the TCM syndrome efficacy of the trial group was significantly superior to that of the control group(P＜0.05).(4)After treatment,systolic blood pressure and diastolic blood pressure were improved in both groups compared to those before treatment(P＜0.05),and the improvement in the trial group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the scores of all domains(physical,psychological,social relationships,and environmental)of WHO-QOL-BREF scale were significantly improved in both groups compared to those before treatment(P＜0.05),and the improvement in the trial group was significantly superior to in the control group(P＜0.05).(6)After treatment,SAS and SDS scores were significantly improved in both groups compared to those before treatment(P＜0.05),and the improvement in the trial group was significantly superior to that in the control group(P＜0.05).(7)No significant adverse reactions occurred in either group during the treatment period,indicating high safety.(8)Sankey diagram and correspondence analysis showed that patients aged＜65 years,male,grade 1 hypertension,mild anxiety,and mild depression achieved significant hypotensive effect and symptom-relief effect(P＜0.05).Conclusion Pinggan Capsules have significant clinical efficacy in treating hypertension complicated with anxiety and depression of liver-yang hyperactivity type and is worthy of clinical promotion and application.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Objective:To investigate the characteristics of gastrointestinal (GI) symptom spectrum in patients with Parkinson′s disease (PD), and to help the early identification of gastrointestinal symptoms and management of PD.Methods:One hundred PD patients in the Department of Neurology, Peking Union Medical College Hospital from January 2017 to August 2017 were enrolled in this study. They were assessed by face-to-face GI dysfunction questionnaire, including eight common symptoms involved in oropharynx, upper and lower digestive tract. The Spearman correlation analysis was performed.Results:The age of PD patients was (61.9±10.5) years, the ratio of male to female was 53∶47 and the disease duration was 4.0 (2.0, 6.0) years. There were 42 cases of Hoehn-Yahr (H-Y) stage 1, 30 cases of H-Y stage 2 and 28 cases of H-Y stage 3 and above (24 cases of H-Y stage 3, three cases of H-Y stage 4 and one case of H-Y stage 5). Totally 58% (58/100) of PD patients had one or more GI symptoms. Constipation (42%, 42/100), dysdefecation (38%, 38/100) and salivation (28%, 28/100) were the top three of most common GI symptoms. Lower GI symptoms were the most common (57%, 57/100), followed by oropharyngeal symptoms (33%, 33/100), and upper GI symptoms (27%, 27/100). GI symptoms could appear in H-Y stage 1 patients, 26.1% (11/42) of which had 1-2 kinds of GI symptoms and over 20% of which had more than three kinds of GI symptoms. A total of 39.3% (11/28) of PD patients with H-Y stage ≥3 had more than three kinds of GI symptoms. The Gastroparesis Cardinal Symptom Index (GCSI) score in patients with upper GI symptoms was 3.0 (2.0,6.5). The constipation symptom score in patients with constipation and dysdefecation was 19.0 (12.0,27.3). As for the clinical type of constipation, 66.7% (38/57) of them were mixed, 21.0% (12/57) were slow transit and 12.3% (7/57) were dysdefecation. In 38.6% (22/57) of the constipated patients, constipation symptoms occurred earlier than PD motor symptoms. Correlation analysis showed that H-Y stage was positively correlated with the course of PD, the number of GI symptoms, salivation, constipation, dysdefecation and constipation symptom scores.Conclusions:Constipation, dysdefecation and salivation were the most common GI symptoms in PD patients. PD patients had at least one GI symptom in the early stage (H-Y stage 1). Lower GI symptoms were more common than oropharyngeal symptoms and upper GI symptoms. With the development of PD, the number of GI symptoms, salivation, constipation and dysdefecation were aggravated, which were important for early symptomatic identification and disease management.

Objectives To evaluate the effectiveness and safety of peramivir trihydrate in patients with influenza.Methods This was a randomized,double-blind,double-dummy,placebo and positive control,multicenter clinical trial,comparing peramivir trihydrate with oseltamivir and placebo.The inclusive criteria were 15-70 years old,onset within 48 h,positive rapid influenza antigen test,and febrile(＞38℃) accompanied with at least two associated symptoms.The severe cases complicated with chronic pulmonary and cardiac diseases,malignancies,organ transplantation,hemodialysis,uncontrolled diabetes,immunocompromised status,pregnancy and coexistence of bacterium infections were excluded.All patients were randomized 2:2:1 to receive peramivir,oseltamivir and placebo respectively.The primary endpoint was the disease duration,the secondary endpoints included time to normal axillary temperature and normal living activities,viral response,and adverse effects.Results Following informed consent,133 patients were included in this study.Four patients were exclude due to missing medical records,not fitting inclusion or exclusion criteria and poor compliance.A total of 129 patients were finally analyzed,including 49 cases,54 cases and 26 cases in peramivir group,oseltamivir group and placebo group.The median disease duration were 96 (76,120)hours,105(90,124) hours,and 124 (104,172)hours in three groups respectively(P＞0.05).The time to normal axillary temperature,normal living activities and viral response were not significantly different in three groups(P＞0.05).Conclusion The value of antiviral therapy in patients with mild influenza needs to be further determined.

Objective To investigate the stimulated proliferation of colon cancer cells in co-cultures of regenerating hepatocytes. Methods Regenerating hepatocytes(24 hours after partial hepatectomy)were obtained by collagenase perfusion of models of rats undergoing 70% liver resection. To determine whether the ratio of human colon cell line SW480 cells to hepatocytes in co-cultures has influence on their interaction,these cells were cultured in ratios of 1: 101:1, or 10: 1. Proliferation capacity was assessed by the percentage of 3 H-TdR incorporation. Expression of epidermal growth factor receptor(EGFR), insulin-like growth factor1 receptor(IGF-1R)and hepatocyte growth factor receptor(c-met) were analyzed by western blot. Results For co-cultured SW480 and hepatocytes in the ratios of 1: 1 and 1: 10, an increase of disintegrations per minute(dpm) occurred after 72 hours' culture, and lasted at 120 hours' culture(P < 0.05). No difference was found between the group with ratio of 10:1 and control group. Protein levels of EGFR and IGF-1R, but not c-met, were significantly increased between culture of 24 hours and 120 hours; however, no change of these receptors was found in the ratio of 10: 1. Conclusions These results imply that co-culturing human colon cancer cells with regenerating hepatocytes leads to increased expression of EGFR and IGF-1R. We conclude that this effect is probably dependent on paracrine stimulation, by which numerous signals from the hepatocytes contribute to the hyperproliferative state of colon cancer cells via up-regulating the responding receptors.
