Hepatic alveolar echinococcosis is a highly invasive zoonotic parasitic disease with poor prognosis. Surgical intervention serves as the pivotal approach to achieve radical cure and improve the prognosis of hepatic alveolar echinococcosis patients. In recent years, with the popularization of the concept of precision surgery and the development of the multidisciplinary diagnosis and treatment model, the surgical treatment strategies for hepatic alveolar echinococcosis have been continuously enriched, and the selection of surgical procedures has become increasingly diversified. Although key surgical techniques such as radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation have achieved remarkable progress in clinical application, many insurmountable challenges still remain. Therefore, by sorting out the latest evidence-based advances in the field of surgical treatment for hepatic alveolar echinococcosis, this article focuses on discussing the application status and bottlenecks of radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation in hepatic alveolar echinococcosis, aiming to provide a reference for the clinical treatment of hepatic alveolar echinococcosis.

Objective To investigate the effects of Xuetong capsule on blood lipids and liver lesion in hyperlipidemic model animals. Methods Sixty ICR mice were randomly divided into six groups. The normal control group was fed with normal diet, the other groups were fed with high-fat diet to induce hyperlipidemia. After four weeks feeding, the three groups were given low, middle, and high doses of Xuetong capsules （0.5, 1.0, and 2.0 g/kg） by gavage, and the positive drug control group was given atorvastatin calcium （1.5 mg/kg） by gavage. The model group was given solvent （0.5% carboxymethyl cellulose sodium）. After treatment for 8 weeks, the body weight, organ index, blood lipids, blood glucose and liver function index were measured. The liver oil red staining was used to determine the lipid droplet content, and quantitative PCR was used to detect the expression of inflammatory factors TNF-α, IL-6, and IL-1β. Results The body weight, the weight of liver and spleen were significantly increased by high-fat diet. High-fat diet increased the organ indexes of the liver and spleen, the degree of liver oil red staining, and also significantly increased the levels of glucose, triglyceride （TG）, cholesterol （CHOL）, and low-density lipoprotein cholesterol （LDL-C） in serum. Compared with the model group, the level of TG has no significant change in low, middle and high doses groups. The level of CHOL in serum was reduced by Xuetong capsule with a dose dependent manner. There were significant difference between the model group and middle, high doses groups. The results of LDL-C were similar, the level of LDL-C was significantly reduced by middle and high doses groups [middle dose (0.55±0.21) mmol/L, high dose (0.52±0.22) mmol/L vs (0.81±0.29) mmol/L in model group, P<0.05]. Compared with the normal control, there was no significant difference in HDL-C levels between the high-fat model and each drug-treated group. Liver function showed that Xuetong capsules significantly reduced the degree of liver oil red staining and decreased the level of alanine aminotransferase （ALT） induced by high-fat diet. The body weight, the weight and organ indexes of liver and spleen were significantly reduced by positive drug control group. The levels of CHOL, LDL-C, and TG, and the degree of liver oil red staining were also significantly reduced in positive drug control group. Further studies have shown that high dose of Xuetong capsules significantly reduced the expression of TNF-α and IL-6 induced by high-fat diet （P<0.05）, while the reduction of IL-1β was not so significant （P>0.05）. Conclusion Xuetong capsules significantly reduced the body weight of animals with high fat, liver size, fat deposition, inflammatory damage and also significantly reduced blood lipid CHOL and LDL-C levels and transaminase elevation. The above effects may be related to Xuetong capsules reducing the expression of inflammatory factors such as TNF-α and IL-6 in the liver.

OBJECTIVE To investigate the effects of different sterilization methods on 3D-printed polylactic acid(PLA)guide plates for orthopedic surgery,and to analyze their physical properties,microbial contamination,structural performance and bio compatibility after sterilization.METHODS PLA guide plates for orthopedic surgery were prepared with 3D printing technology and divided into a blank group,a hydrogen peroxide plasma steriliza-tion group,an ethylene oxide sterilization group and a pressure steam sterilization group.Before and after sterili-zation,the changes in volume and weight of the surgical guide plates were measured,microbial detection was con-ducted,structural changes were observed with a laser scanning confocal microscope,and cell co-culture was con-ducted to evaluate biocompatibility,thereby the effects of different sterilization methods were assessed.RESULTS The three sterilization methods had no significant effect on the volume and weight of PLA surgical guide plates.Microbial detection showed that all three sterilization methods were effective in killing bacteria,and bacte-rial cultures were negative.Laser confocal scanning microscopy revealed that sterilization treatment caused certain changes to the microstructure of the surgical guide plates,but high-temperature sterilization had a more pro-nounced effect on the deformation of the guide plate edges.Cell co-culture results indicated that the surgical guide plates treated with the three sterilization methods exhibited acceptable cytotoxicity and had little effect on cell pro-liferation.CONCLUSIONS All three sterilization methods cause microstructural changes to the surgical guide plate.Among them,pressure steam sterilization significantly deforms the structure of the guide plate,directly af-fecting its precise positioning of mutual spatial distances,angular relationships and orientation during surgery.Al-though hydrogen peroxide plasma sterilization does not cause significant deformation,ethylene oxide sterilization has the least impact on material properties and structural stability while ensuring the sterilization effect of PLA surgical guide plates.

Objective To explore the effect of a phased rehabilitation training programme to relieve shoulder dys-function in patients after neck dissection and to provide effective solutions for postoperative shoulder joint function recov-ery of patients.Methods This study has been reviewed and approved by the Ethics Committee,and informed consent has been obtained from patients.A phased rehabilitaiton training programme for the shoulder after neck dessection was developed through literature review and discussion,and 70 eligible patients from Hospital of Stomatology,Sun Yat-sen University from December 2020 to April 2021 were selected and randomly divided into the test group and control group(35 patients in each group).The control group underwent motor rehabilitation training from 6 weeks postoperative to 1 year after surgery,such as shoulder mobility and coordination training and small range of motion training of the neck,while the test group took part in a rehabilitation training program that included familiarization maneuver training,protective rehabilitation,exercise rehabilitation,and resistance training in the following four stages:preoperative,postop-erative general anesthesia and awake until the removal of stitches,the removal of stitches until 6 weeks after surgery,and 6 weeks after surgery until 1 year after surgery.The frequency of training in both groups was at least 3 days per week,and the length of each training session was 10-15 min.The intensity of exercise was 2-3 points on the Borg Conscious Ex-ercise Intensity Scale(i.e.,mild-to-moderate tachypnea or fatigue).The neck dissection injury index(NDII)was used to evaluate the quality of life related to shoulder joint function at four time points:preoperative,postoperative 3 months,postoperative 6 months,and postoperative 12 months.The higher the score,the better the quality of life.Results 28 cases in the test group and 32 cases in the control group completed a one-year follow-up.At 3 and 6 months postopera-tive,the NDII of the test group was significantly higher than that of the control group[3 months postoperative:test group(93.48±9.36)vs.control group(80.00±11.34)(P＜0.001),6 months postoperative:test group(98.21±4.76)vs.control group(90.70±9.12)(P＜0.001)];12 months after surgery,the NDII of the test group(97.23±4.88)was still higher than that of the control group(96.33±4.49),but the difference was not statistically significant(P=0.458).The difference in NDII scores among subjects at 3,6,and 12 months after surgery was statistically significant in each group(P＜0.001).Conclusion The application of the phased rehabilitation training method in neck dissection patients has a feasibility and could improve the quality of life of patients'shoulder joint function within 6 months after surgery.

Over the past decade, traditional Chinese medicine (TCM) has widely embraced systems biology and its various data integration approaches to promote its modernization. Thus, integrative pharmacology-based traditional Chinese medicine (TCMIP) was proposed as a paradigm shift in TCM. This review focuses on the presentation of this novel concept and the main research contents, methodologies and applications of TCMIP. First, TCMIP is an interdisciplinary science that can establish qualitative and quantitative pharmacokinetics-pharmacodynamics (PK-PD) correlations through the integration of knowledge from multiple disciplines and techniques and from different PK-PD processes

Objective:To investigate the status of innovative behavioral ability of undergraduate nursing students, analyze the relationship between nursing students′ sense of benefit, self-transcendence and innovative behavioral ability, and explore the mediating effect of occupational benefit in self-transcendence and innovative behavioral ability.Methods:A convenient sampling method was used to select 223 undergraduate nursing students in the First Affiliated Hospital of Guangxi University of Chinese Medicine as the research object from October 2017 to April 2019. The cross-sectional survey was conducted using the occupational benefit, self-transcendment scale and nurses′ innovative behavior scale. Apply SPSS21.0 to analyze the correlation between self-transcendence, occupational benefit and innovative behavior of undergraduate nursing students, apply AMOS 22.0 for mediating effect test, and use the bias-corrected percentile Bootstrap method to estimate the median effect of occupational benefit 95% confidence interval.Results:The path coefficient of undergraduate nursing students′ self-transcendence to innovative behavioral ability was significant ( r value was 0.31, P<0.01). Self-transcendence had a significant positive effect on positive occupational sense ( r value was 0.36, P<0.05). The 95% confidence interval for the Bootstrap test of the indirect effect of positive occupationality was 0.02-0.07; the positive sense of occupation had a partial mediating effect between self-transcendence and innovative behavioral ability, with an effect value of 0.14 and a total effect value of 0.42. That was, the mediation effect value accounted for 33.3% of the total effect value. The path coefficient of the team's ability to feel innovative behavior was significant ( r value was 0.39, P<0.05), and self-transcendence had a positive impact on team belonging ( r value was 0.28, P<0.01). The 95% confidence interval for the Bootstrap test for the indirect effects of team belonging was distributed in 0.10-0.42. The sense of belonging of the team had a partial mediating effect between self-transcendence and innovative behavioral ability. The mediating effect value was 0.07, and the total effect value was 0.42, that was, the mediating effect value accounts for 16.7% of the total effect value. Conclusions:Self-transcendence of undergraduate nursing students can directly predict the ability of innovative behavior, and can also indirectly predict the ability of innovative behavior through the mediating role of positive career perception and team belonging in the sense of professional benefit. Improving the professional benefit and self-transcendence of nursing students in clinical teaching may be an effective way to improve the ability of innovative behavior.
