Objective:To investigate the effect of laparoscopic splenectomy and azygoportal disconnection (LSD) on liver synthesis and development of liver cirrhosis.Methods:This is a prospective case series study.The clinical data of liver cirrhotic patients with portal hypertension who received LSD at the Department of Hepatobiliary Surgery of Northern Jiangsu People′s Hospital Affiliated to Yangzhou University from September 2014 to January 2016 were included. This study analyzed the diameter of the portal vein, the velocity of portal blood flow, the routine blood parameters, the liver function, the synthetic proteins of liver (antithrombin Ⅲ (AT-Ⅲ), protein S, protein C), and the serum content of liver fibrotic markers(collagen type Ⅳ, procollagen type Ⅲ, laminin, hyaluronidase). Repeated measures ANOVA was used for comparison between multiple groups, and least significance difference was used for post-hoc multiple comparison.Results:A total of 106 patients were included in the study, including 70 males and 36 females, aged (51.8±9.8) years(range: 28 to 75 years).Compared with the preoperative results, the diameter of portal vein and the velocity of portal vein decreased after surgery ( F=14.03, 12.15, respectively, both P<0.01). Compared with the preoperative results, the total bilirubin, albumin, prothrombin time, international normalized ratio, Child-Pugh score and classification were improved ( F=17.96, 56.01, 66.63, 35.83, 33.49, and 27.50, respectively, all P<0.01), and the AT-Ⅲ, protein S, protein C,collagen type Ⅳ, procollagen type Ⅲ, laminin and hyaluronidase levels were also improved ( F=47.87, 36.26, 18.02, 2.79, 14.58, 44.35, and 14.38, respectively, all P<0.01). Compared with the preoperative period, the diameter of portal vein was reduced from the first week to the 24 th month after surgery ( t=5.45 to 9.39, all P<0.01). Compared with the preoperative period, the velocity of portal vein blood from the first week after surgery to the 24 th month after surgery was decreased ( t=4.02 to 8.43, all P<0.01). Compared with the preoperative period, routine blood parameters (white blood count, hemoglobin, platelet count), liver function (total bilirubin, albumin, prothrombin time, international normalized ratio, Child-Pugh score), liver synthetic protein (AT-Ⅲ, protein S, protein C) and liver fibrotic markers (collagen type Ⅳ, procollagen type Ⅲ, laminin, hyaluronidase) were improved to varying degrees at the 24th month after surgery ( t=-20.46 to 11.93, all P<0.01). Conclusion:Preliminary findings show that LSD can reduce portal vein pressure, restore blood cell number, and improve liver synthesis function and the degree of liver fibrosis in patients with portal hypertension in liver cirrhosis.

ObjectiveTo explore the mechanism of Yishen Huashi granules in alleviating renal tubular epithelial cell injury and relieving diabetic kidney disease by regulating the mitogen-activated protein kinase （MAPK） signaling pathway. MethodsThe db/db mice of 12 weeks old were randomly assigned into model ， dapagliflozin （1.6 mg·kg^-1）， and Yishen Huashi granules （4.7 g·kg^-1）， and db/m mice were used as the control group. The general conditions of mice were observed， and fasting blood glucose and 24-h urinary protein and albumin-to-creatinine ratio （ACR） were measured at weeks 0 and 12 of administration. After 12 weeks of treatment， the levels of serum creatinine （SCr）， blood urea （UREA）， triglycerides （TG）， total cholesterol （TC）， and low density lipoprotein （LDL） were measured. The pathological changes in the renal tissue were observed by hematoxylin-eosin （HE） staining， Periodic acid-Schiff （PAS） staining， Mallory staining， and transmission electron microscopy. Real-time PCR was employed to determine the mRNA levels of monocyte chemotactic protein-1 （MCP-1） and CC chemokine receptor-2 （CCR2） in the renal tissue of mice. The immunohistochemical assay was employed to examine the expression of p38， phospho-p38 （p-p38）， MCP-1， and CCR2 in the renal tissue of mice. Western blotting was employed to measure the protein levels of p-p38， p38， MCP-1， and CCR2 in the renal tissue of mice.HK-2 cells cultured in vitro were grouped as follows： negative control， high glucose（30 mmol·L^-1）， Yishen Huashi granule-containing serum， and SB203580. After 48 h of cell culture in each group， RNA were extracted and the levels of MCP-1， and CCR2 mRNA were determined by Real-time PCR，proteins were extracted and the levels of p38， p-p38， MCP-1， and CCR2 were determined by Western blot. ResultsThe in vivo experiments showed that before treatment， other groups had higher body weight， blood glucose level， 24 h urinary protein， and ACR than the control group （P<0.05，P<0.01）. After 12 weeks of treatment， compared with the model group， the Yishen Huashi granules group showed improved general conditions， a decreasing trend in body weight， lowered levels of blood glucose， 24-h urinary protein， and ACR （P<0.01）， reduced SCr and UREA （P<0.01）， and declined levels of TC， TG， and LDL （P<0.05，P<0.01）. Compared with the model group， the Yishen Huashi granules group showed alleviated damage and interstitial fibrosis in the renal tissue as well as reductions in glomerular foot process fusion and basement membrane thickening. Moreover， the Yishen Huashi granules group showed down-regulated mRNA levels of MCP-1 and CCR2 （P<0.01）， reduced positive expression of p-p38， MCP-1， and CCR2 （P<0.01）， and down-regulated protein levels of p-p38/p38， MCP-1， and CCR2 （P<0.05） in the renal tissue. The cell experiment showed that compared with the high glucose group， the Yishen Huashi granule-containing serum group showcased down-regulated mRNA levels of MCP-1 and CCR2 （P<0.01） and down-regulated protein levels of p-p38/p38， MCP-1， and CCR2（P<0.05，P<0.01）. ConclusionYishen Huashi granules can regulate glucose-lipid metabolism， reduce 24 h urinary protein and ACR， improve the renal function， alleviate the renal tubule injury caused by high glucose， and protect renal tubule epithelial cells in db/db mice by reducing MCP-1/CCR2 activation via the p38 MAPK signaling pathway.

ObjectiveTo investigate the mechanism of Shenkang injection in delaying diabetic kidney disease by regulating endoplasmic reticulum stress and attenuating podocyte apoptosis through the Glucose regulated protein 78 （ GRP78 ） / transcription factor C / EBP homologous protein （ CHOP ） signaling pathway （GRP78/CHOP） signaling pathway. MethodsFor the animal experiment， 10 12-week-old db/m mice were selected as a normal group， and 30 12-week-old db/db mice were randomly divided into a model group， a Shenkang injection group （15.6 mL·kg^-1）， and a dapagliflozin group （1.6 mg·kg^-1）. To observe the general condition of mice， fasting blood glucose， urinary albumin/urine creatinine （ACR）， and 24 h urine protein quantification were detected in each group before drug administration. After 12 weeks of drug treatment， mice were tested for fasting blood glucose， total cholesterol （TC）， triglyceride （TG）， low-density cholesterol （LDL）， ACR， 24 h urine protein quantification， blood creatinine （SCr）， and blood urea （UREA）. Hematoxylin-eosin （HE） staining， periodic acid-Schiff （PAS） staining， and transmission electron microscopy were used to observe the pathologic morphology in renal tissue. Immunohistochemistry was used to detect the expressions of nephroprotective marker protein （Nephrin）， glucose-regulated protein 78 （GRP78）， CCAAT/enhancer-binding protein homologous protein （CHOP）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in renal tissue. Western blot was used to detect the expressions of GRP78， CHOP， Bcl-2， Bax， and Nephrin proteins， and Real-time polymerase chain reaction （Real-time PCR） was employed to detect the expressions of Nephrin， GRP78， CHOP， Bcl-2， and Bax mRNAs in renal tissue. ResultsBefore drug administration， compared with those in the normal group， the body mass of db/db mice was significantly increased， and blood glucose， 24 h urine protein quantification， and ACR were significantly elevated in the Shenkang injection group and Dapagliflozin group （P<0.01）. After 12 weeks of administration， compared with those in the model group， the general state of mice in the Shenkang injection group was significantly improved， and the body mass was decreased. The blood glucose was significantly reduced （P<0.01）， and blood lipids TC， TG， and LDL were significantly decreased （P<0.05， P<0.01）. The 24 h urine protein quantification and ACR were significantly decreased （P<0.05）， and SCr and UREA were significantly reduced （P<0.01）. Compared with those of the model group， the pathologic results of the Shenkang injection group showed that proliferation of mesangial cells， reduction of inflammatory cell infiltration， and alleviation of renal tubular vacuolization and podocyte damage were observed in renal tissue of mice. Electron microscopy showed that fusion of the pedicle protruding and thickening of the basement membrane were reduced. Immunohistochemistry results showed that the expressions of GRP78， CHOP， and Bax proteins were significantly reduced （P<0.01）， and the expressions of Nephrin and Bcl-2 proteins were significantly increased （P<0.01） in renal tissue of the Shenkang injection group. Western blot results showed that the expressions of Nephrin and Bcl-2 in the Shenkang injection group were significantly increased （P<0.05， P<0.01）， and the expressions of GRP78， CHOP， and Bax proteins were significantly decreased （P<0.05， P<0.01）. Real-time PCR results showed that the expressions of GRP78， CHOP， and Bax mRNAs were down regulated in the Shenkang injection group （P<0.01）， and the expressions of Nephrin and Bcl-2 mRNAs were up regulated （P<0.01）. ConclusionShenkang injection inhibits endoplasmic reticulum stress response and podocyte apoptosis by regulating the GRP78/CHOP signaling pathway， which in turn ensures the integrity of glomerular filtration barrier， reduces the occurrence of proteinuria， improves renal function， and thus delays the progression of diabetic kidney disease.

The nine groups of physical parameter monitoring, the first type of chemical indicator monitoring, and the five types of chemical PCD monitoring for lumen sterilization achieved 100% qualification rates, and there were no significant differences in the qualified rates of sterilization among the 9 groups (P>0.05). ConclusionWhen using hydrogen peroxide low temperature plasma to sterilize thoracoscopic instruments, it is recommended to use stainless steel or silicone resin rigid containers with a controlled loading capacity (≤12) to ensure optimal sterilization quality.

ObjectiveTo analyze the temporal distribution characteristics of crisis calls and eight major counseling issues to the Shanghai mental health hotline, and to provide recommendations for improving hotline management. MethodsDescriptive statistics were used to analyze 1 106 crisis calls and the calls of eight major counseling issues to the Shanghai mental health hotline across months, time periods and weeks from October 2021 to September 2023, and the chi-square test was used to analyze whether there was any difference in the distribution of 1 106 crisis calls and the calls of eight major counseling issues across months, time periods and weeks. ResultsThere were significant differences in the number of crises calls across different months (χ²=87.816, P<0.05), time periods (χ²=161.848, P<0.05), and weekly distributions (χ²=63.329, P<0.05). The highest number of calls occurred in September, while January had the lowest. The peak call times were between 18:00‒20:00, with the fewest calls occurring between 3:00‒5:00. The day of the week with the highest number of calls was Saturday, while Wednesday had the lowest. Among the different types of counselling issues in crisis calls, the highest number of calls were related to mental disorders, while the fewest calls were related to COVID-19. ConclusionCrisis calls to the Shanghai mental health hotline are concentrated at specific times, indicating that relevant organizations should optimize resource allocation based on this time distribution.

Objective To analyze the effect of different retained dosage of lauromacrogol within the thyroid cyst in the sclerotherapy of thyroid cysts.Methods A total of 200 patients with thyroid cysts,who were admitted to the Longyan Municipal First Hospital of China between August 2020 and August 2021,were enrolled in this study.The patients were randomly and equally divided into group zero(suctioning out all the amount of the injected lauromacrogol),and,according to the percentage of the retained lauromacrogol dosage to the total cystic fluid,group 10%,group 20%,group 30%and group 50%,with 40 patients in each group.Thyroid color ultrasound was reviewed at 1,3,6,and 12 months after treatment.The changes of capsule volume,curative efficacy,influencing factors,and adverse reactions after the cyst became sclerosis were analyzed.Logistic regression analysis was used to analyze the factors affecting the postoperative efficacy.Results In all the 5 groups,the suctioned fluid was dark red in colour,and the patients had cystic nodules.The preoperative mean cyst volume was(20.43±5.86)cm3.In all the 5 groups,the postoperative changes in cyst volume indicated that the postoperative one-month cyst volume significantly shrank when compared with the preoperative volume,the postoperative 3-month cyst volume remarkably shrank when compared with the postoperative one-month volume,and the postoperative 6-month cyst volume strikingly shrank when compared with the postoperative 3-month volume(all P＜0.05),while no statistically significant difference in the cyst volume existed between the postoperative 12-month value and the postoperative 6-month value(P＞0.05).The postoperative 6-month total effective rate of all the five groups was 87%(174/200),and no statistically significant differences in the postoperative 6-month curative effect existed between each other among the 5 groups(P＞0.05).Taking the postoperative 6-month curative effect as the dependent variable,and the age,sex,thick cystic wall,cystic septum,and preoperative cyst volume as independent variables,the binary logistic regression analysis was conducted,which revealed that the thick cystic wall(OR=0.24,95%CI=0.08-0.72,P=0.01)and the cystic septum(OR=0.21,95%CI=0.07-0.67,P=0.01)were the factors affecting the postoperative 6-month curative effect.The main side reaction was pain,which was tolerable by patients.There was no significant difference in the incidence of adverse reactions between each other among the five groups(all P＞0.05).Conclusion In treating thyroid cysts by using ultrasound-guided lauromacrogol sclerotherapy,there is no relationship between the curative effect and the percentage of the retained lauromacrogol dosage to the total cystic fluid.The best curative effect can be achieved at 6 months after injection of lauromacrogol,which can be used as the optimal time for follow-up check.The thick cystic wall and the cystic septum are the main factors that affect the curative effect of lauromacrogol sclerotherapy.For the treatment of thyroid cyst,lauromacrogol sclerotherapy carries reliable curative effect with few adverse reactions,therefore,this therapy is worthy of clinical application.(J Intervent Radiol,2024,32:69-73)

Methods: Twenty-four rats of the SD strain were randomly divided into the negative control group, PFASs group and protein powder group, with 8 rats (half males and half females) in each group. PFASs included 13 perfluorocarboxylic acids (PFCAs) and 8 perfluorosulfonic acids (PFSAs), and the mixture was used as a test subject for intervention. The rats in the negative control group were given deionized water at doses of 20 mL/kg·bw, in the PFASs group were given 5 mL/kg·bw of PFASs mixtures and 15 mL/kg·bw of deionized water, and in the protein powder group were given 5 mL/kg·bw of PFASs mixtures and 15 mL/kg·bw of protein powder (0.258 g/mL). After intervention for 28 successive days, body weight and kidney mass were weighed, and the kidney volume index was calculated. Serum creatinine and blood urea nitrogen were detected by an automatic biochemical analyzer. The PFCAs, PFSAs and PFASs contents were quantified in blood and kidney using ultra-high performance liquid chromatography-electrospray tandem mass spectrometry, and the bioavailability was estimated. Results: There was no significant differences in kidney mass, kidney volume index, serum creatinine and blood urea nitrogen among the negative control group, PFASs group and protein powder group (all P>0.05). The bioavailability of blood PFCAs, PFSAs and PFASs in the protein powder group was not significantly different from the PFASs group (all P>0.05). Compared with the PFASs group, the bioavailability of PFCAs, PFSAs and PFASs were significantly increased in kidneys of male rats in the protein powder group (all P<0.05), while were not significant different in those of female rats (all P>0.05). Conclusion Protein powder at the dose of this study can significantly improve the bioavailability of PFASs in kidneys of male rats, while there no obvious effects on the bioavailability of blood PFASs and renal function.
