Objective To evaluate the long-term efficacy of transjugular intrahepatic portosystemic shunt(TIPS)with bare stents and Fluency covered stents in the treatment of portal hypertension,and to discuss its clinical value.Methods The clinical data of 29 patients with intractable ascites or esophagogastric fundus varices rupture and hemorrhage caused by cirrhotic portal hypertension,who received TIPS with bare stents and covered stents at the First Affiliated Hospital of Xinjiang Medical University of China(25 patients)and the Lishui Municipal Central Hospital of China(4 patients)between August 2012 and December 2017,were retrospectively analyzed.The patients were regularly followed up to check the survival status.The postoperative cumulative shunt patency rate and cumulative survival rate of the patients were analyzed by Kaplan-Meier method.Results The technical success rate of TIPS was 100％.The mean portal vein pressure was decreased from preoperative(40.21±3.24)cmH2O to postoperative(24.55±3.55)cmH2O(P＜0.05).The patients were followed up for 5.1-10.5 years.The postoperative 1-,3-,5-,7-year primary cumulative patency rates of the shunt were 89.7％,75.9％,75.9％ and 52.5％,respectively.The postoperative 5-,7-,9-and 10-year cumulative survival rates were 100％,66.9％,66.9％ and 33.4％,respectively.The incidence of hepatic encephalopathy was 13.8％(4/29).Conclusion Using bare stents combined with Fluency covered stents for TIPS is clinically safe and effective in the treatment of portal hypertension.This technique carries higher long-term shunt patency rate and low incidence of hepatic encephalopathy.Therefore,it can be used as a substitute for Viatorr stent when necessary.(J Intervent Radiol,2024,33:295-299)

This article systematically analyzes the historical evolution of the name， origin， scientific name evolution， medicinal parts， producting area， harvesting and processing， clinical efficacy of Paridis Rhizoma by consulting the ancient materia medica， medical books and prescription books， combined with modern literature， in order to provide a reference for the development of famous classical formulas containing Paridis Rhizoma. According to research， it can be verified that Paridis Rhizoma was first recorded in Shennong Bencaojing with the name of Zaoxiu， and this name has been used for ancient materia medica in the past generations. The name of Chonglou was first appeared in Xinxiu Bencao of the Tang dynasty， and has gradually become the rectification of name， with it being the correct name in modern legal names at all levels. The mainstream source of Paridis Rhizoma used in ancient times was the dried rhizomes of Paris polyphylla var. chinensis， but due to the similarity plant morphology of the genus Paris， there was much confusion， and the same genus of plants with thick rhizomes were also used as Paridis Rhizoma， such as P. polyphylla， P. polyphylla var. stenophylla. Since modern times， P. polyphylla var. yunnanensis has also been included as one of the mainstream sources of Paridis Rhizoma. The origin recorded in ancient materia medica are mainly in Shandong， Anhui， Jiangsu， Jiangxi， Yunnan and other regions， which are collected in the wild for medicinal purposes， modern cultivation is more prevalent in southwestern regions， such as Yunnan， Sichuan， Guizhou and Guangxi. In ancient times， the harvest time was mostly root harvesting in April and May of the lunar calendar， while in modern times， they are mostly harvested throughout the year or in autumn. Autumn harvesting is the best choice， with roots removed from the production area， washed， and dried in the sun. In ancient times， Paridis Rhizoma was processed by baking， grinding and other methods， but in modern times， sliced raw products were mainly used as medicine. Paridis Rhizoma has a slightly cold nature， a bitter taste， and a small toxicity. It can regulate the liver meridian， clear heat and detoxify， reduce swelling and pain， cool the liver and calm convulsions. It is used for symptoms such as boils and carbuncles， throat swelling and pain， snake and insect bites， and its flavor and efficacy are basically consistent in ancient and modern records. Based on the results of the textual research， it is recommended that the dried rhizomes of P. polyphylla var. chinensis or P. polyphylla var. yunnanensis should be used in the development of famous classical formulas containing Paridis Rhizoma， the processing method is selected according to the requirements of the formula， and the raw product is recommended to be used as medicine if not specified.

Objective: To investigate the mechanism of action of Wuzi Yanzong pill (WYP) in rats with oligoasthenozoospermia (OAZ) via metabolomics and to provide a possible basis for improving this WYP-based treatment. Methods: A rat model of OAZ was established by treating male Sprague–Dawley rats with glucosides from Tripterygium wilfordii Hook. F. Seventy-two rats were randomly divided into six groups: control, L-carnitine (positive control), model, and low-, medium-, and high-dose WYP groups. Rats in the experimental groups were treated with WYP for 4 weeks. At the end of the treatment period, sperm cell quality (density, motility, and viability) was assessed using a semen analysis system, mitochondrial membrane potential (MMP) was assessed using flow cytometry, and testicular injury was assessed using hematoxylin and eosin staining to validate the therapeutic effect of WYP in OAZ. Further, serum metabolomics-based analysis was performed using high-performance liquid chromatography-mass spectrometry to identify differential metabolic pathways and possible mechanisms of action of WYP in OAZ treatment. Results: A rat model of OAZ was considered successfully-established after comparing the quality of spermatozoa in the model group to that in the control group. WYP-M and WYP-H treatments significantly improved sperm cell density, motility, and viability compared with those in the model group (all P < .05). Compared with the model group, both WYP-M and WYP-H treatments increased MMP values (P = .006 and P = .021 respectively), while there was no significant difference in the L-carnitine group. L-carnitine and WYP administration reversed damage to the testes to varying degrees compared with that in the model group. Further, 44 differential metabolites and four metabolic pathways, especially autophagy pathway, related to OAZ were identified via metabolomics. Conclusions WYP improves sperm cell quality and MMP in OAZ primarily via autophagy regulation. These findings can be employed to improve the efficacy of WYP in humans.

Pancreatogenic diabetes is a type of diabetes mellitus secondary to exocrine pancreatic disease,and it was officially proposed by the American Diabetes Association in 2014,with chronic pancreatitis as the most common etiology,followed by pancreatic cancer.At present,the misdiagnosis rate of this disease is extremely high,and patients with pancreatogenic diabetes have a higher risk of death and readmission than patients with type 2 diabetes.Therefore,it is of great significance to fully understand,correctly identify,and diagnose pancreatogenic diabetes in the early state,so as to reduce the disability rate and mortality rate of this disease.This article reviews the advances in the possible pathogenesis,diagnosis,treatment,and management of pancreatic diabetes secondary to pancreatitis and pancreatic cancer.

Objective To evaluate the mechanism of governor vessel electroacupuncture in rats with post-stroke limb spasm by observing the changes of glutathione antioxidant system-related factors.Methods A total of 60 SD rats were randomly divided into the normal group(n=12),sham operation group(n=12)and modeling group(n=36).The middle cerebral artery obstruction model was prepared by thread approach method in the modeling group,and 24 rats with successful modeling were randomly divided into the model group and the electroacupuncture group,with 12 rats in each group.At the 3rd day after modeling,the electroacupuncture group was treated with electroacupuncture at three acupoints of the governor vessel,namely,"Dazhui"(GV14),"Jizhong"(GV6)and"Houhui"(anteromedial of the transverse process of the sixth lumbar vertebra),for 30 min each time,once a day for 7 days.The neurological function of rats was assessed by Zea Longa neurological deficit score.The muscle tension of rats was detected by modified Ashworth dystonia rating and electrophysiological tracing method.The brain tissue water content was measured by the dry-wet weight method.The volume of cerebral infarction of rats was measured by the TTC staining method.The contents of glutathione(GSH),catalase(CAT),oxidized glutathione(GSSG),superoxide dismutase(SOD),and malondialdehyde(MDA)in the cortex of rats were detected by colorimetry.The protein and mRNA expressions of glutathione reductase(GR),glutamate cysteine ligase(GCL)C,GCLM,and glutathione peroxidase 4(GPX4)in the cortex of rats were measured by Western blotting and real-time PCR,respectively.Results Compared with rats in the normal and sham operation groups,the Zea Longa neurological deficit score,modified Ashworth dystonia rating,the volume of cerebral infarction,brain tissue water content,and GSSG and MDA contents in cortex were increased in the model group,the tension signal value and the proteins and mRNA expressions of GR,GCLC,GCLM,and GPX4 in cortex were decreased,and the contents of GSH,CAT,and SOD in cortex were decreased(P＜0.05).Compared with the model group,the Zea Longa neurological deficit score,modified Ashworth dystonia rating,the volume of cerebral infarction,brain tissue water content,and GSSG and MDA contents in cortex were decreased in the electroacupuncture group,the tension signal value and the proteins and mRNA expressions of GR,GCLC,GCLM,and GPX4 in cortex were increased,and the contents of GSH,CAT,and SOD in cortex were increased(P＜0.05).Conclusion Governor vessel electroacupuncture can improve the severity of post-stroke limb spasm in rats,and its mechanism may be related to the regulation of glutathione antioxidant system in cerebral cortex.

Objective:To investigate the quantification assessment of segmental volume after thigh liposuction utilizing three-dimensional(3D) scanning technology.Methods:This retrospective study was performed with the analysis of 3D scanning images of patients who had undergone bilateral thigh liposuction in Body Contouring & Fat Grafting Center, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from January 2018 to September 2022. Preoperative and postoperative 3D scanning were performed to build visual 3D models of bilateral thighs. From top to the bottom, bilateral thighs were segmented into seven sections with a space of 5 cm in acquired 3D model. Certain measurements and calculation of preoperative and postoperative volume and volume change rate of the overall thigh and each segment were conducted, to validate the efficiency of liposuction (EOL). Additionally, EOL of each thigh segment was computed and the symmetry of bilateral thighs was analyzed before and after surgery. The volume differences were computed using the paired Wilcoxon rank-sum test, and intraclass correlation coefficient (ICC) was exerted to assess the symmetry of bilateral thighs before and after surgery.Results:A total of 36 female patients were included in the study, with an age range of 18 to 49 years and a mean age of (28.6±7.6) years. Follow-up duration ranged from 23 to 1 133 days postoperatively, with a mean follow-up period of 274.7 days. The results of 3D scanning measurements indicated significant changes ( P<0.01) in both the overall volume of the thigh and the volumes of each segment before and after surgery. The highest volume change rate and EOL were observed in the uppermost segment, and the volumetric change rate and EOL exhibited a descending trend across the segments of the thigh from the uppermost to the lowermost segments. The ICC of the volume of each segment consistently surpassed 0.950 whether preoperatively or postoperatively, indicating a high level of symmetry between the bilateral thighs, and the ICC of overall volume showed a notable increase from 0.992 preoperatively to 0.997 postoperatively. Conclusion:3D scanning technology can be exerted to quantify the volume changes before and after thigh liposuction. This study provided quantitative and objective evidence to confirm the efficacy of thigh liposuction procedure, elucidating that the most significant liposuction effects observed in the uppermost segment of the thigh. Moreover, postoperative assessments reveal a further enhancement in bilateral thigh symmetry.

Objective:To investigate the intention to stay on among primary health care workers (PHWs) during the COVID-19 epidemics and its influencing factors.Methods:An online questionnaire survey was conducted among PHWs from 62 primary health institutions in 31 provinces, autonomous regions and municipalities across China selected by multi-stage whole cluster random sampling method between May and October 2022. According to the job position, the PHWs were divided into 5 categories: general practitioners (GPs), nurses, public health doctors, managers and support staff. Intention to stay was measured using the Chinese version of the Intention to Stay Questionnaire. Multiple linear regression model was used to analyze the influencing factors of the intention to stay in PHWs of different occupational categories, including personal factors, work factors, factors related to the COVID-19 and psychological reactions.Results:A total of 3 769 PHWs from 44 community health service centers, 18 township hospitals of 27 provinces/autonomous regions and 4 municipalities participated in this survey. The mean age of participants was (37.4±9.2) years, including 2 971(78.8%) women. The mean score of intention to stay of participants was 21.7±4.1. Compared with GPs, managers had lower intention to stay ( P=0.004). Age, female, in marriage, monthly income, years of primary care service, self-evaluation of unit support function, MSQ-SF score, and PA score were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 score, EE score, and DP score were negatively correlated with the score of intention to stay (all P<0.05). The MSQ-SF scores of all occupational categories were positively correlated with the scores of intention to stay (all P<0.01). In addition, among GPs, monthly income, years of service in primary care, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 scores and EE scores were negatively correlated with the score of intention to stay (all P<0.05). Among nurses, age, female gender, monthly income, self-evaluation of unit support function, and PA score were positively correlated with the score of intention to stay (all P<0.05), while EE scores and retention will score were negatively associated with ( P<0.001). Among public health doctors, in marriage was positively correlated with the score of intention to stay ( P=0.018). Among managers, DP score was negatively correlated with the score of intention to stay ( P=0.001). Among support staff, female gender, monthly income, years of primary care service, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while EE score and DP score were negatively correlated with intention to stay (all P<0.05). Conclusions:The intention to stay of PHWs in China during the COVID-19 was at an intermediate level, which was affected by many factors. Among them, job satisfaction was positively correlated with the intention to stay of all occupational categories, and the influencing factors of different occupational categories have some variations.

Objective:To investigate the diagnostic value of magnetically controlled capsule gastroscope in elderly patients with suspected upper gastrointestinal bleeding.Methods:A total of 102 patients with suspected upper gastrointestinal bleeding who underwent magnetically controlled capsule gastroscopy (MCCG) in General Hospital of Ningxia Medical University from October 2020 to September 2022 were enrolled. Patients were divided into two groups according to age: 38 patients in group A (≤65 years old) and 64 patients in group B (> 65 years old). The case data, changes of vital signs, detection of lesions and adverse reactions of the two groups were compared.Results:There were significant differences in combined diseases between group A and group B. The stomach examination time in group A was significantly shorter than that of group B (15.49±2.04 min VS 16.61±2.02 min, t=-2.685, P=0.009). There was significant difference in small intestine examination time between the two groups (331.69±14.96 min VS 337.83±14.28 min, t=-1.229, P=0.227). The incidence of adverse reactions in group A was significantly lower than that in group B [0.00%(0/38) VS 6.25%(4/64), χ2=6.186, P=0.013]. The changes of vital signs before, during and after examination were not statistically different. The detection rates of upper gastrointestinal lesions were 92.1% (35/38) and 98.4% (63/64), respectively. The positive rates of upper gastrointestinal bleeding under MCCG were 60.0% (21/35) and 50.8% (32/63), respectively. Patients with unexplained upper gastrointestinal bleeding under MCCG received small intestine examination. The detection rates of small intestinal lesions by small intestine examination were 84.6% (11/13) and 91.7% (22/24), respectively. Conclusion:MCCG demonstrates excellent diagnostic accuracy in elderly patients with suspected upper gastrointestinal bleeding. Additionally, it is safe and suitable for use in elderly patients with multiple comorbidities, allowing for concurrent small intestine examination.
