OBJECTIVE To explore the regulatory mechanism of Danshen decoction on dyslipidemia in hyperlipidemia model rats. METHODS The experimental rats were divided into blank group （n＝9， no modeling）， model group （n＝8， modeling）， and Danshen decoction group （n＝9， modeling）. Starting from the 9th week of feeding with the high-fat diet， rats in the Danshen decoction group were given the corresponding medication solution （3.6 g/kg） intragastrically， while blank group and model group were given equal volume of normal saline， once a day， for 4 consecutive weeks. After 4 weeks of administration， the plasma levels of triglycerides （TG）， total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were measured in each group of rats； the pathological and morphological changes of liver tissue were observed； the differential proteins between samples were screened out by TMT quantitative proteomic analysis； the expression levels of the key differentially expressed proteins in the liver， including epoxide hydrolase 2 （EPHX2）， perilipin 2 （PLIN2）， peroxisome proliferator activated receptor γ （PPAR γ） and glycogen synthase kinase-3β （GSK-3β）were detected. RESULTS Compared with the model group， the plasma levels of TC， TG and LDL-C in the Danshen decoction group were significantly reduced （P＜0.05）， while the level of HDL-C was significantly increased （P＜0.05）. The liver tissue of rats inmodel group showed uneven staining， disordered arrangement of liver plates， disappearance of liver sinusoids， nuclearcondensation or disappearance of some cells， swelling and fusion of cytoplasm， proliferation of connective tissue， and diffuse vacuolar-like fat droplet changes. The liver tissue of Danshen decoction group showed varying degrees of improvement in the above pathological and morphological. The results of differential protein analysis showed that the total number of differential proteins was 298 between the model group and the blank group； the total number of differential proteins was 139 between the model group and Danshen decoction group. Compared with the model group， the expression levels of EPHX2 and PLIN2 proteins in the liver tissue of rats in the Danshen decoction group were significantly reduced （P＜0.01）， while the expression levels of GSK-3β and PPARγ were significantly increased （P＜0.01）. CONCLUSIONS Danshen decoction has a significant improvement effect on the plasma lipid levels and the pathological and morphological of the liver tissue in hyperlipidemia model rats. Its regulatory mechanism may be related to the up-regulation of PPARγ and GSK-3β expression and down-regulation of EPHX2 and PLIN2 expression， and the signaling pathways involved may include PPAR-γ signal pathway.

ObjectiveTo decipher the mechanism of Danshenyin in regulating platelet activation in the rat model of hyperlipidemia by means of proteomics and molecular biology. MethodWistar rats were randomized into blank， model， and Danshenyin groups （n=10） according to the blood lipid level. The rats in the blank group were fed with a basic diet， and those in the model and Danshenyin groups with a high-fat diet. All the rats had free access to water and food. The treatment began at the 9th week. The rats in the Danshenyin group were administrated with Danshenyin by gavage at a crude drug dose of 3.6 g·kg^-1. The rats in the model and blank groups were administrated with an equal volume of normal saline according to body weight. At the 12th week， the tissue samples were collected for the measurement of related indicators， and the blood lipid level was measured by an automatic biochemical analyzer. The whole blood viscosity and plasma viscosity were measured by an automatic hemorheometer. The platelet proteome was determined by liquid chromatography-mass spectrometry. Western blotting was employed to determine the protein levels of platelet membrane glycoprotein 4 （CD36）， focal adhesion kinase （FAK）， phosphatidylinositol 4-phosphate 5-kinase （PIP5K）， phosphorylated phosphatidylinositol 3-kinase （p-PI3K）， protein kinase B （Akt）， and phosphorylated protein kinase B （p-Akt）. ResultCompared with the model group， Danshenyin lowered the levels of total cholesterol （TC）， triglyceride （TG）， and low-density lipoprotein cholesterol （LDL-C） in the plasma （P<0.05）， elevated the level of high-density lipoprotein cholesterol （HDL-C） （P<0.05）， and reduced the platelet aggregation rate （P<0.05）. Compared with the blank group， the modeling up-regulated the expression of 44 proteins and down-regulated the expression of 12 proteins. Compared with the model group， Danshenyin up-regulated the expression of 21 proteins and down-regulated the expression of 22 proteins. Compared with the blank group， Danshenyin up-regulated the expression of 31 proteins and down-regulated the expression of 49 proteins. The gene ontology （GO） functional enrichment showed that the differentially expressed proteins were mainly involved in cholesterol transport and efflux， production of cytokines， dyslipidemia， and platelet activation. The Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment showed that the differentially expressed proteins were mainly involved in ECM-receptor interaction， peroxisome proliferators-activated receptors （PPAR）， focal adhesion， and PI3K/Akt signaling pathways. Danshenyin can significantly down-regulate the expression of CD36， FAK， PIP5K， PI3K， p-Akt （Ser473）， and p-Akt1/2/3 （Thr308）. ConclusionDanshenyin can restore the blood lipid level of hyperlipidemia rats and inhibit the platelet activation caused by abnormal lipid levels by down-regulating the CD36/PI3K/Akt signal cascade.

Objective:To explore the characteristics, prevention and treatment strategies of lower urinary tract injury in transvaginal reconstructive pelvic surgery (vRPS).Methods:A retrospective analysis was conducted on 24 patients who suffered lower urinary tract injuries occuring in vRPS from January 2005 to June 2021, among which 4 cases were referred to our hospital from other hospitals.Results:(1) In our hospital, 1 952 patients underwent vRPS for anterior and (or) middle pelvic organ prolapse during that study period, with a 1.0% (20/1 952) incidence of lower urinary tract injuries occurring in 20 cases. (2) Ureteral injuries were observed in 14 cases who underwent transvaginal high uterosacral ligament suspension (1.4%, 14/966). The symptoms were relieved after the removal of sutures. (3) Bladder injuries occurred in 6 cases in our hospital, with 4 cases (0.7%, 4/576) in anterior transvaginal mesh surgery (aTVM), one (0.4%, 1/260) in colpocleisis, and one (0.7%, 1/150) in apical suspension for fornix prolapse. An additional 4 cases of bladder injury were referred to our hospital after aTVM. Among the 8 cases of bladder injury during aTVM, 2 cases were intraoperative incidents. Cystoscopy confirmed that the superficial branch or puncture rod of anterior vaginal mesh had penetrated into the bladder. Re-puncturing and placement of the mesh were successfully performed. No abnormalities were observed during a follow-up period of 4-5 years. Postoperative bladder injuries were identified in 6 cases, characterized by mesh erosion into the bladder and formation of calculi. These injuries were confirmed between 6 months to 2 years after vRPS. The exposed mesh and calculi in the bladder were removed through laparotomy or cystoscopy, followed up for 2-12 years. One case experienced slight re-erosion of mesh to the bladder.Conclusions:Lower urinary tract injuries are difficult to avoid in vRPS, particularly in transvaginal high uterosacral ligament suspension and aTVM. However, the incidence is low. Lower urinary tract injuries during vRPS could be easily detected and managed intraoperatively because of the use of cystoscopy. As long-term postoperative complications, erosion of transvaginal mesh to lower urinary tract postoperatively could be treated correctly, seldom with severe sequelae.

OBJECTIVE To investigate the effects of Buyang huanwu decoction on red blood cells in hyperlipidemia model mice. METHODS Male C57BL/6 mice were fed a high-fat diet to prepare a hyperlipidemia model. Successfully modeled mice were randomly assigned to the model group， atorvastatin calcium group （0.26 g/kg）， fenofibrate group （1.3 mg/kg）， and high-， medium-， and low- dose groups of Buyang huanwu decoction （18.6， 9.3， 4.6 g/kg）， with 10 mice in each group. Additionally， 10 mice fed with regular chow served as the normal group. Each group of mice received intragastric administration with the corresponding drug or normal saline once daily for 21 consecutive days. After the last administration， the body weight of the mice in each group was measured， and blood glucose， total cholesterol （TC）， triglyceride （TAG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） levels were measured. Red blood cell morphology changes were observed， and the expression levels of glucose transporter type 1 （GLUT1）， erythrocyte membrane protein band 4.2 （protein 4.2）， caveolin-1， and flotillin-1 in erythrocyte membrane were determined. RESULTS Compared with the model group， the body weight and levels of TC， TAG， HDL-C， LDL-C， and the expression levels of GLUT1， caveolin-1 and flotillin-1 in the Buyang huanwu decoction groups were significantly decreased， while blood glucose levels and the expression levels of protein 4.2 were significantly increased （P＜0.05）. The red blood cell morphology in the low- and medium-dose groups of Buyang huanwu decoction was significantly promoted. CONCLUSIONS Buyang huanwu decoction can reduce blood lipid levels in hyperlipidemia model mice and strengthen the morphology and function of red blood cells in a hyperlipidemic environment， which has the potential to be used for preventing hyperlipidemia complications such as atherosclerosis.

OBJECTIVE To investigate the effects and mechanism of Danshen decoction influencing platelet physiological characteristics and function in hyperlipidemia model rats based on platelet membrane glycoprotein 4 （CD36）/phosphatidylinositol 3- kinase （PI3K）/protein kinase B （Akt） signaling pathway. METHODS The hyperlipidemia model rats were induced by feeding high- fat diet， and then randomly divided into model group， simvastatin group （0.004 g/kg）， Danshen decoction high-dose and low-dose groups （3.6， 0.9 g/kg）， and blank group （fed with basic feed）， with 10 rats in each group. Rats in each administration group were intragastrically administered with corresponding drugs every day， and the other groups were intragastrically administered with equal volume of normal saline for 4 weeks. After the last administration， the contents of blood lipid biochemical indexes [total cholesterol （TC）， triglyceride （TG）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）]， whole blood viscosity， plasma viscosity and fibrinogen （FIB）content in plasma， platelet-related parameters [platelet count （PLT）， platelet distribution width （PDW） and mean plateletvolume （MPV）] were detected. The levels of plateletphysiological characteristics and function-related factors [von Willebrand factor （vWF）， fibronectin （Fn）， phospholipase A2（PLA2）， thromboxane B2 （TXB2）， 6-keto-prostaglandin F1α （6-keto-PGF1α）， thromboxane A2 （TXA2）， prostaglandin I2 （PGI2）， cyclic adenosine monophosphate （cAMP）， cyclic guanosine monophosphate （cGMP）， β-thromboglobulin （β-TG）]， platelet aggregation rate （maximum aggregation rate， 60 s aggregation rate， 180 s aggregation rate） and fibrinolytic system-related factors [tissue plasminogen activator （t-PA）， plasminogen activator inhibitor 1 （PAI-1）] and the expressions of CD36/PI3K/Akt signaling pathway-related proteins [CD36， focal adhesion kinase （FAK）， phosphatidylinositol 4-phosphate 5-kinase （PIP5K）， PI3K， phosphorylated Akt （p-Akt）， p-Akt1/2/3] in platelet were all determined. RESULTS Compared with blank group， the contents of TC， TG and LDL-C in plasma， whole blood viscosity， plasma viscosity， the plasma levels of FIB， PLT， MPV， vWF， Fn， PLA2， TXB2， TXA2， cGMP and β-TG， maximum platelet aggregation rate， 60 s aggregation rate， the expressions of PAI-1 in plasma， protein expressions of CD36， FAK， PIP5K， PI3K， p-Akt and p-Akt1/2/3 were significantly increased in the model group （P＜0.05）. The content of HDL-C and the levels of 6-keto-PGF1α， PGI2 and t-PA were significantly decreased （P＜0.05）. After the intervention of Danshen decoction， most of the above indexes were significantly reversed （P＜0.05）. CONCLUSIONS Danshen decoction can improve the physiological characteristics and function of platelets in hyperlipidemia model rats， and its mechanism may be related to the down-regulation of CD36/PI3K/Akt signaling pathway activity and the reduction of platelet activation.

CONCLUSIONS ：Buyang huanwu decoction can significantly improve the pathological state in hyperlipidemia model rats by reducing blood viscosity and FN content ，improving platelet adhesion，enhancing fibrinolytic activity ，improving platelet aggregation ，inhibiting hypercoagulability and hyperplatelet release.

As a collective noun of incense and medicine, fragrant medicine has long been integrated into Chinese culture. It is not only a symbol of the cultural exchange between China and foreign countries in the middle ancient times, but also plays a very important role in medicine and other fields. Among them, Borneol can not only be used for medicinal purposes, but also for incense and fumigation, as well as food, tea, wine and other applications. This paper intends to sort out the medicinal properties, effects and other applications of Borneol recorded in ancient books of traditional Chinese herbs in the past dynasties, focusing on summarizing its medicinal properties, meridians, effects, compatibility and application characteristics. In addition, modern pharmacological action was included as a supplement, in order to provide reference for the clinical use of Borneol in medicinal aspects.

Objective:To evaluate the indications, surgical skills and clinic outcomes of abdominal minimal incision sacrocolpopexy (AMISC) for treatment of advanced pelvic organ prolapse (POP).Methods:The retrospective study analyzed 30 women with advanced POP who underwent AMISC between June 2016 and October 2019, including 9 cases of recurrent prolapse and 10 cases of vault prolapse. AMISC was especially applicable to: (1) patients with several medical complications who was unable to tolerate general anesthesia or laparoscopic surgery, but able to tolerate combined spinal-epidural anesthesia and open surgery; (2) other abdominal procedures were indicated to perform with AMISC simultaneously, such as myomectomy, subtotal hysterectomy etc, the specimens were easy to get out of the abdominal cavity and morcellation was avoided; (3) surgeons preferring open surgery to laparoscopic surgery or skilled in open surgery; (4) patients with prior pelvic operations, presenting severe abdominal and pelvic adhesions. Objective outcomes were assessed by pelvic organ prolapse quantification (POP-Q) system. Subjective outcome were assessed by pelvic floor distress inventory-short form 20 (PFDI-20), pelvic floor impact questionnaire-short form (PFIQ-7) and patient global impression of improvement (PGI-I).Results:All patients with 1-3 medical complications were successfully performed with AMISC without stopping procedure, enlarging the incision or changing to other procedure, the operation duration was (110±19) minutes. The mean time of follow-up was (33.5±12.4) months (range: 8-49 months). The postoperative points of Aa, Ba, C, Ap, Bp reduced significantly and point C improved from (2.33±2.50) cm to (-7.54±1.18) cm after AMISC ( P<0.01). The objective cure rates were both 100% (30/30) in apex and posterior compartment, while 97% (29/30) in anterior compartment. Postoperative scores of PFDI-20 and PFIQ-7 were all significant decreased (all P<0.01). About PGI-I, 29 patients chose “significant improvement”, subjective satisfaction was 97% (29/30). Anterior sacral plexus hemorrhage occurred in 2 cases (7%, 2/30). There was no intestinal obstruction or injury of bladder, bowel and ureter intra- and postoperation. Two cases (7%, 2/30) had mesh exposure. Conclusion:AMISC is a safety, convenient, minimal traumatic and durable procedure for apical prolapse with short learning curve in the most of cases.

Compared with model group ，the contents of TG ，TC， LDL-C and HMG-CoA reductase in administration groups as well as the contents of ALT ，AST in Buyang huanwu decoction low-dose and high-dose groups were decreased significantly （P＜0.05 or P＜0.01）；the contents of HL and MTP in administration groups as well as the content of LPL in positive control group were increased significantly （P＜0.05 or P＜0.01）. Pathological sections showed that the hepatocytes of model group were arranged irregularly ，and there was obvious cell steatosis. The hepatocytes in positive control group and Buyang Huanwu decoction high-dose group had almost no abnormal change compared with blank control gr oup，and there was a small amount of slight cell steatosis in Buyang Huanwu decoction low-dose group. CONCLUSIONS ： Buyang huanwu decoction has a 础。E-mail：zhang520-888@163.com significant lipid-lowering effect on hyperlipemia model rats ，which may be related to the regulation of lipid absorptiontransport and metabolism by regulating the expression of lipid 126.com metabolism related enzymes and transporter.

OBJECTIVE：To investigate the protective effect an d possible m echanism of Shenqi zhilong decoction （SZD） combined with Tripterygium polyglycoside tablets （TPT）on membranous nephropathy （MN）model rats. METHODS ：MN rat model was established by subcutaneous and caudal vein injecting cationic bovine serum albumin + incomplete Freund adjuvant emulsion for 6 weeks. At the 3rd week of modeling ，model rats were randomly divided into model control group ，SZD low-dose and high-dose groups （4，8 g/kg，by total crude drugs ），TPT group （9 mg/kg），low-dose and high-dose of SZD+TPT groups （same dose as single group ），with 10 rats in each group according to 24 h UTP and weight. Another 10 rats withoutmodeling were taken as blank control group. Blank control group was given equal amount of water intragastrically administration groups were given relevant medicine intragastrically，once a day ，for consecutive 4 weeks. The 24 h UTP of rats were detected one day before the last administration；1 h after the la st administration ，blood routine 中indexes（WBC，RBC，PLT），liver func tion indexes （TP，ALB，AST，ALT），blood lipid indexes （TC，TG，HDL-C，LDL-C）， the contents of glucose （GLU），urea nitrogen （BUN）and serum creatinine （Scr）were detected in each group. Uranyl acetate-lead citrate staining was used to observe ultrastructural changes of renal tissue. Immunohistochemical method was used to detect the protein expression of TGF-β1 and HPA- 1 in renal tissue. RESULTS ：Compared with blank control group ，in the model control group，the glomerular podocytes were widely fused or disappeared ，microvilli were formed ，basement membrane was heavily thickened，a large number of electron dense substance was deposited under the epithelium ，TGF-β1 and HPA- 1 positive cells were significantly increased ；24 h UTP ，PLT，the contents of TC ，TG and HDL-C ，the percentage of TGF-β1 and HPA- 1 positive cells were increased significantly ，while RBC ，the contents of TP and ALB were decreased significantly （P＜0.05 or P＜0.01）. Compared with model control group ，above ultrastructural changes of administration groups were improved to different extents ，and TGF-β1 and HPA- 1 positive cells were decreased. The 24 h UTP ，the percentage of TGF-β1 positive cells （except for SZD low-dose group），WBC（except for SZD alone groups and combination groups ），PLT and TC content （except for TPT group ），TG content （except for SZD low-dose alone and its combination group ），the percentage of HPA- 1 positive cells were decreased significantly ； the percentage of TGF-β1 positive cells in SZD high-dose+TPT group as well as the percentage of HPA- 1 positive cells in SZD+TPT groups were significantly lower than TPT group. RBC and GLU content （except for SZD low-dose group and TPT group ），TP and ALB content （except for SZD low-dose group ）were increased significantly ，while the content of GLU in SZD high-dose+TPT group was significantly higher than TPT tablets group （P＜0.05 or P＜0.01）. CONCLUSIONS ：SZD combined with TPT can relieve myelosuppression caused by TPT ，reduce proteinuria of MN model rats and improve pathological damage of renal tissue in rats. Its mechanism is related to the down-regulation of protein expression of TGF-β1 and HPA- 1，and the reduction of TC and TG content in the blood.
