Abstract
To investigate the safety and efficacy of "quadri-combination" therapy including maximal transurethral resection of bladder tumor (mTURBT), combined with systemic chemotherapy and immunotherapy, concurrent radiotherapy, and immune maintenance therapy. The clinical data of 8 patients with bladder cancer who could not tolerate or refused radical cystectomy at the Department of Urology, Peking University Cancer Hospital from November 2019 to October 2021 were retrospectively analyzed. There were 5 males and 3 females with a mean age of 69 years. The Eastern Cooperative Oncology Group(ECOG) score was 0 in 6 cases and 1 in 2 cases. There were 5 cases of high-grade urothelial carcinoma (1 case of T3b; 2 cases were T2; 2 cases of T1 stage, with multiple tumors and repeated recurrence), 1 case of high-grade urothelial carcinoma with carcinoma in situ (T1/Tis stage), 1 case of high-grade urothelial carcinoma with squamous differentiation (T3b stage), and 1 case of high-grade urothelial carcinoma with glandular differentiation (T2). All patients underwent "quadri-combination" therapy.The patient's tolerance, success rate of bladder preservation and prognosis were evaluated.The median follow-up time was 22.5 (12-35) months. One patient with high-grade muscle-invasive bladder cancer (T2) received mTURBT, albumin-bound paclitaxel and durvalumab combined therapy for 3 cycles, concurrent radiotherapy, and immune maintenance therapy for 18 months, and the tumor recurrence was found. The pathology was high-grade urothelial carcinoma. Salvage radical cystectomy combined with pelvic lymph node dissection is recommended. The remaining 7 patients were regularly reexamined, and no recurrence or metastasis was found.The 2-year progression-free survival rate was 80%, and the success rate of bladder preservation was 87.5%(7/8). Treatment-related adverse reactions were resolved by symptomatic treatment, and patients' compliance and tolerance were acceptable.The "quadri-combination" bladder-preserving therapy is feasible and well tolerated, but further studies are needed.

Abstract
Objective: To explore the safety and efficacy of laparoscopic microwave ablation combined with partial nephrectomy in the treatment of renal tumors. Methods: The 65 patients with renal tumors undergoing laparoscopic microwave ablation combined with partial nephrectomy from November 2017 to May 2021 were retrospectively analyzed. There were 46 males and 19 females. The average age was (56.6±14.1) years. The mean body mass index was (25.7±3.3) kg/m2. The tumors located in the left kidney in 30 cases and the right kidney in 35 cases. The ECOG score was 0 in 59 patients and 1 in 6 patients. The mean maximum diameter of the tumors was (2.3±1.0) cm(1.0-5.0 cm). According to R.E.N.A.L. scoring, 41 cases were of low difficulty (4-6 points), 23 cases of medium difficulty (7-9 points) and 1 case of high difficulty (10-12 points). The renal tumors were ablated by laparoscopic microwave ablation, then followed by partial nephrectomy. Postoperative complications were observed and the prognosis was assessed by CT or MRI. Results: The mean duration of operation was (76.6±19.4) min (40-120 min). The median intraoperative blood loss was 20 ml(5-50 ml). The median duration of postoperative hospitalization was 4 d(3-6 d). Complications of Clavien grade Ⅰ were found in 11 patients (fever, nausea and vomiting, lumbar pain), and no complications were grade Ⅱ or above. Postoperative pathology showed that no positive margin was found, and 46 cases of clear cell renal cell carcinoma (AJCC stage: T1a stage 42 cases, T1b stage 4 cases; WHO/ISUP classification: 21 cases of grade 1, 23 cases of grade 2, 2 cases of grade 3); 2 cases of type 1 papillary renal cell carcinoma (stage T1a, grade 1); 1 case of type 2 papillary renal cell carcinoma (T1b stage, grade 2); 2 cases of renal chromophobe carcinoma (all stage T1a); 1 case of low-grade malignant potential multilocular cystic renal tumor; 2 cases of adenocarcinoma (combined with the postoperative history of rectal cancer, metastasis was considered); 6 cases of renal angiomyolipoma; 2 cases of eosinophiloma; 1 case of papillary adenoma; 1 case of benign renal cyst and 1 case of renal hemangioma with calcification. The median follow-up was 24 months (1-42 months). Sixty-three patients survived and two died (one due to heart disease and one due to metastatic colorectal cancer). According to postoperative imaging, there were no signs of tumor recurrence or metastasis in other cases. Blood tests were performed regularly, and no significant abnormalities occurred. Conclusions: The safety and efficacy of laparoscopic microwave ablation combined with partial nephrectomy for the treatment of renal tumor is satisfactory, such as less intraoperative bleeding, fewer complications, less effect on renal function and postoperative pathology, providing a potential option for renal tumor treatment.

Abstract
BACKGROUND Angiotensin converting enzyme 2 (ACE2) has recently been identified as the functional receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent response for novel coronavirus disease 2019 (COVID-19). This study aimed to explore the roles of ACE2, apelin and sodium-glucose cotransporter 2 (SGLT2) in SARS-CoV-2-mediated cardiorenal damage. METHODS AND RESULTS The published RNA-sequencing datasets of cardiomyocytes infected with SARS-CoV-2 and COVID-19 patients were used. String, UMAP plots and single cell RNA sequencing data were analyzed to show the close relationship and distinct cardiorenal distribution patterns of ACE2, apelin and SGLT2. Intriguingly, there were decreases in ACE2 and apelin expression as well as marked increases in SGLT2 and endothelin-1 levels in SARS-CoV-2-infected cardiomyocytes, animal models with diabetes, acute kidney injury, heart failure and COVID-19 patients. These changes were linked with downregulated levels of interleukin (IL)-10, superoxide dismutase 2 and catalase as well as upregulated expression of profibrotic genes and pro-inflammatory cytokines/chemokines. Genetic ACE2 deletion resulted in upregulation of pro-inflammatory cytokines containing IL-1β, IL-6, IL-17 and tumor necrosis factor α. More importantly, dapagliflozin strikingly alleviated cardiorenal fibrosis in diabetic db/db mice by suppressing SGLT2 levels and potentiating the apelin-ACE2 signaling. CONCLUSION Downregulation of apelin and ACE2 and upregulation of SGLT2, endothelin-1 and pro-inflammatory cytokines contribute to SARS-CoV-2-mediated cardiorenal injury, indicating that the apelin-ACE2 signaling and SGLT2 inhibitors are potential therapeutic targets for COVID-19 patients.

Abstract
Euphorbiae pekinensis Radix (EP) is effective in treating various diseases, but it's toxicity is a major obstacle in use in clinical. Although EP was processed with vinegar to reduce it's toxicity, the detailed mechanism of toxicity in EP have not been clearly delineated. This study investigate the toxicity attenuation-mechanism of Euphorbiae pekinensis after being processed with vinegar (VEP) and the toxic mechanism of four compounds from EP on zebrafish embryos. The contents of four compounds decreased obviously in VEP. Correspondingly, slower development on embryos can be seen as some symptoms like reduction of heart rate, liver area and gastrointestinal peristalsis after exposed to the compounds. Some obvious pathological signals such as pericardial edema and yolk sac edema were observed. Furthermore, the compounds could increase the contents of MDA and GSH-PX and induce oxidative damage by inhibiting the activity of SOD. Also, four compounds could provoke apoptosis by up-regulating the expression level of p53, MDM2, Bax, Bcl-2 and activating the activity of caspase-3, caspase-9. In conclusion, the four compounds play an important role in the toxicity attenuation effects of VEP, which may be related to the apoptosis induction and oxidative damage. This would contribute to the clinical application and further toxicity-reduction mechanism research.

Abstract
The dried roots of Euphorbia kansui (EK) are especially beneficial for the treatment of edema, but the severe toxicity limits their clinical applications. Euphorbia kansui stir-fried with vinegar (VEK) is traditionally employed to reduce the toxicity of EK. However, the material basis for the toxicity reduction with effectivity conservation is still unclear. Therefore, in this study, a rapid, sensitive, and reliable ultra-fast liquid chromatography tandem mass spectrometry (UFLC-MS/MS) method was firstly established to simultaneously determine six ingenane-type diterpenoids, i.e. kansuiphorin C (1), 5-O-benzoyl-20-deoxyingenol (2), 20-deoxyingenol (3), 3-O-(2'E,4'E-decadienoyl)-20-O-acetylingenol (4), 20-O-(2'E,4'Z-decadienoyl)ingenol (5), and ingenol (6), in EK and VEK based on the processing conversion. Then, the toxicity evaluation on zebrafish embryos and modulation of the expression of aquaporin-3 (AQP3) proteins in HT-29 cells were employed to investigate the toxicity-activity of six compounds. Chromatographic separation was obtained on Waters BEH RP18 column (2.1 mm × 100 mm, 2.5 μm) with the mobile phase composed of 0.1 % formic acid in acetonitrile and water, respectively. The column temperature was 35 ℃ at a flow rate of 0.4 mL min-1. Multiple reaction monitoring was conducted in both positive and negative modes for quantitative analysis. The method was then successfully used for the determination of six compounds in EK and VEK. In addition, 1, 2, 4, and 5 had evident cardiotoxicity, intestinal irritation and nutrient absorption disorders on zebrafish larvae, while no in-vivo toxicity was seen for groups given 3 and 6 (LC50 > 200 μM). Meanwhile, 1, 2, 4, 5, and 6 significantly increased the expression of AQP3 protein (p < 0.05) to promote the excretion of water in the colon. This study demonstrated that toxic ingenane-type diterpenoids converted into the less toxic compounds with the same core structure through the breakage of multiple ester bonds in the side chain. At the same time, the laxative effect was retained, providing useful information for the optimization of the process of EK and quality evaluation of other similar toxic Chinese herbal medicines.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Euphorbia kansui is a toxic Chinese herbal medicine and exhibits promising treatment to the malignant ascites (MA) in its traditional use. Ingenane-type and jastrophane-type diterpenes are demonstrated to be responsible for the toxicity and efficacy of kansui. Two representative compounds, kansuiphorin C (KPC) and kansuinin A (KA) in each type were proved to effectively reduce the ascites. The biological and toxicological effects are closely associated with the gastrointestinal tract, but the possible mechanism and related metabolic functions of KPC and KA treating MA through modulating the gut microbiota remain unclear. AIM OF THE STUDY To investigate the possible mechanism and related metabolism of KPC and KA ameliorating malignant ascites through modulating gut microbiota. MATERIALS AND METHODS MA rats and normal rats were divided into different groups and administrated with KPC, KA, and positive drug, respectively. 16S rDNA gene sequencing and metagenomes analysis combined with the quantification of short-chain fatty acids of feces were performed to reflect the modulation of gut microbiota. Then, the metabolites of KPC and KA in rat feces under the normal and pathological circumstances were detected by ultra-fast liquid chromatography coupled with MS/MS detector (UFLC-MS/MS) to explore the in-vivo bacterial biotransformation. RESULTS KPC and KA were modulatory compounds for gut microbiota. The richness of Lactobacillus and the decreased abundance of Helicobacter involved in the carbohydrate metabolism and amino acid metabolism could be responsible for their prohibitory effects on malignant ascites. KPC exhibited stronger modulation of gut microbiota through making the abundance of Helicobacter about 3.5 times lower than KA. Besides, in-vivo microbial biotransformation of KPC and KA contained oxidation, hydrolysis, dehydration, and methylation to form metabolites of lower polarity. Besides, at the dosage of 10 mg kg-1, the toxicity of both compounds had weaker influences on the gut microbiota of normal rats. CONCLUSION KPC and KA could ameliorate malignant ascites by modulating gut microbiota mainly containing the increase of Lactobacillus and the decrease of Helicobacter and related carbohydrate and amino acid metabolism, providing a basis for their promising clinical usage.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Eclipta prostrata, a traditional herbal medicine, has long been used in Asia and South America for the therapy of hemorrhagic diseases (e.g. hemoptysis, hematemesis, hematuria, epistaxis and uterine bleeding), skin diseases, respiratory disorders, coronary heart disease, hair loss, vitiligo, snake bite and those caused by the deficiency of liver and kidney. AIM OF THE REVIEW In this review, we highlight relatively comprehensive and up-to-date information of E. prostrata on traditional uses, phytochemistry, pharmacology and toxicity, along with featuring the gaps in current knowledge, aiming to provide references for future research and possible opportunities for well applications of this medicinal plant. MATERIALS AND METHODS Information on E. prostrata was gathered from scientific databases (Google Scholar, Web of Science, Scifinder, Baidu Scholar, PubMed and CNKI). Information was also obtained from local books, Ph.D. theses and M.Sc. dissertations and Chinese Pharmacopoeia. The plant taxonomy was validated by the database "The Plant List". RESULTS Various phytochemical classes has been identified and isolated from the plant covering triterpenes, flavonoids, thiopenes, coumestans, steroids and others. Among these, coumestans are reported as the most common ingredients. The isolated crude extracts and individual compounds have been reported to exhibit promising pharmacological properties, such as hepatoprotective, osteoprotective, cytotoxic, hypoglycaemic, anti-inflammatory, anti-microbial, hypolipidemic, promoting hair growth, rejuvenative and neuroprotective effects. CONCLUSIONS Until now, significant progress has been witnessed in phytochemistry and pharmacology of E. prostrata. Thus, some traditional uses has been well supported and clarified by modern pharmacological studies. Moreover, E. prostrata also showed therapeutic potential in some refractory diseases such as cancer, dementia and diabetes. But, present findings are still insufficient that cannot satisfactorily explain some mechanisms of action. More well-designed studies in vitro especially in vivo are required to establish links between the traditional uses and bioactivities, discover new skeletons and activity molecules, as well as ensure safety before clinical use.

Abstract
Objective: To investigate the incidence of occult cervical lymph node metastasis and the common neck level of metastases in cN0 laryngocarcinoma, and the relationship between the clinicopathologic features of laryngocarcinoma and cervical lymph node metastasis. Methods: A total of 506 cases with cN0 laryngocarcinoma treated at the First Affiliated Hospital of Chongqing Medical University between March 2011 and March 2018 were enrolled, and their medical records and follow-up data were retrospectively analyzed. Of them, 211 cases of were glottic carcinoma in stage T1 without neck dissection and they were observed by clinical follow-up; other 295 cases, including glottic carcinoma, supraglottic carcinoma and hypopharyngeal carcinoma in stage T2-T4 were treated with surgical resection of the primary lesions and selective neck dissection. SPSS 22.0 software was used to analyze the data. Results: The total incidence of cervical lymph node metastasis was 10.87%(55/506), with a lower incidence in T1 stage glottic carcinoma(6/211,2.84%) than that in other cases(49/295,16.61%). The incidence of cervical lymph node metastasis in glottic carcinoma (29/426, 6.81%) was lower than those in supraglottic carcinoma (22/71,30.99%) and subglottic carcinoma (4/9) (χ(2)=35.810,P<0.01).The pN+ rates of glottic carcinoma at T1, T2, T3 were 2.84%(6/211), 5.31%(6/113), 16.05%(13/81), and 19.05%(4/21), respectively (χ(2)=18.572, P<0.01). The pN+ rates of supraglottic carcinoma at T2, T3 and T4 were 3/13, 32.50%(13/40) and 6/13, respectively (χ(2)=3.649,P>0.05). The incidence of cervical lymph node metastasis in poorly differentiated carcinoma (17/42, 40.48%) was higher than those in moderately differentiated carcinoma (26/205, 12.68%) and high differentiated carcinoma(12/246, 4.88%)(χ(2)=36.356, P<0.01). Moreover, 85 pN+ lymph nodes were obtained by selective neck dissection, respectively 43(50.59%) in level Ⅱa, 30(35.29%) in level Ⅲ, 1(1.18%) in level Ⅳ and 11(12.94%) in level Ⅵ. Conclusions: The occult cervical lymph node metastasis was frequently found in cN0 laryngocarcinoma. Selective neck dissection should be performed with surgery for the primary lesions in T3-T4 glottic laryngeal cancer, T2-T4 supraglottic laryngeal cancer and subglottic carcinoma, and the neck dissection for level Ⅱa and Ⅲ is appropriate. It is required to detect pre-laryngeal and pre-tracheal lymph nodes in patients with subglottic laryngeal carcinoma.

Abstract
To study the effects of different fraction of Euphorbiae Pekinensis Radix before and after processing with vinegar on liver and gastrointestinal toxicity of zebrafish embryos,the zebrafish embryos after fertilized 12 h(12 hpf) were exposed to different concentrations of solution until 96 h(96 hpf),for observation of the toxicity response of the liver and gastrointestinal of individual zebrafish embryos. The results showed that toxicity increased in a dose-dependent manner. The liver and gastrointestinal toxicity of the zebrafish embryos in various polar fractions of Euphorbiae Pekinensis Radix before and after processing with vinegar was mainly manifested as slow liver development,smaller liver area,edema of yolk sac,delayed absorption,slowing of gastrointestinal motility,abnormal function of gastrointestinal goblet cell secretion. In addition,the toxicity of different polarity was followed by petroleum ether,dichloromethane,ethyl acetate. The above results indicated that the toxicity was reduced after processing with vinegar,and the fractions of petroleum ether and methylene chloride were the main sites responsible for liver and gastrointestinal toxicity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Kansui, the root of Euphorbia kansui S.L.Liou ex S.B.Ho (E.kansui), is a classical traditional Chinese medicine (TCM) with certain toxicity. According to the theory of TCM, kansui fry-baked wtith vinegar (VEK) possesses low toxicity and mild diuretic and purgative efficacy. In clinical practice, it is commonly used for the treatmtablent of ascites and oliguria. The present study aimed to evaluate the toxicity and efficacy of different fractions of VEK and reveal the underlying material basis by employing an animal model of malignant ascites effusion (MAE) in rats. MATERIALS AND METHODSTA The MAE rats as the model were constructed in SPF male wistar rats by intraperitoneal injection of Walker-256 tumor cells. The MAE rats were used and randomly divided into the control group (normal rats), control groups with different fractions (VEKA, VEKB, VEKC and VEKD), model group (MAE rats), positive control group (model group with furosemide), model groups with different fractions (VEKA, VEKB, VEKC and VEKD). Histopathological observation was used to confirm Walker-256 tumor-bearing organ injuries in rats. For the efficacy evaluation, the ascites and urine volumes, the urinary electrolyte concentrations (Na+, K+ and Cl-) and pH, the ascites levels of pro-inflammatory cytokines (IL-2, IL-6, TNF-α, IFN-γ and VEGF), PRA, the serum levels of Ang II, ALD and ADH, as well as AQP8 protein expression in the gastrointestinal tract were detected. Furthermore, different levels of indicators were measured in the toxicity evaluation of different fractions both on normal and model rats, including serum liver enzymes (AST and ALT), serum oxidative damage parameters (GSH, MDA, LDH and SOD), expressions of inflammatory parameters (NF-κB, ICAM-1 and E-cadherin) and apoptosis signals (caspase-3, -8, -9, Bcl-2 and Bax) in the liver and gastrointestinal tract. RESULTS Walker-256 tumor-bearing malignant ascites effusion rats showed obvious hepatic and gastrointestinal injuries by histopathological observation. In the efficacy evaluation, model rats treated with VEKB and VEKC showed significant urine increase (VEKB, P < 0.01; VEKC, P < 0.01) and ascites reduction (VEKB, P < 0.01; VEKC, P < 0.01). These two fractions also balanced the concentrations of Na+, K+ and Cl- in urine (VEKB, all P < 0.05; VEKC, all P < 0.05), remarkably decreased urinary pH (VEKB, P < 0.01; VEKC, P < 0.01), and reduced the ascites levels of IL-2, IL-6, TNF-α, IFN-γ and VEGF (VEKB, all P < 0.01; VEKC, all P < 0.01) in the model rats. Moreover, levels of PRA, the serum Ang II, ALD and ADH of model rats were decreased after treated by VEKB and VEKC (VEKB, all P < 0.05; VEKC, all P < 0.05). Meanwhile, the expression of gastrointestinal AQP8 of the model rats was also enhanced after treated by VEKB and VEKC (VEKB, P < 0.01; VEKC, P < 0.01). In the toxicity evaluation, although VEKB and VEKC caused toxic indexes moved to the worse aspects in normal rats, nearly all of these indicators notably improved in the model rats. Additionally, VEKA showed no effect on the indicators, either in the efficacy evaluation or in the toxicity evaluation. And VEKD could significantly improve some indicators (urine volume, concentration of K+ in urine, serum MDA, AI and caspase-9) in MAE rats. CONCLUSIONS VEKB and VEKC were demonstrated a significant efficacy in treating malignant ascites effusion, which could reduce hepatic and gastrointestinal damage on the model rats but cause the same damage to the normal. These data embody the traditional Chinese medicine application principle: You Gu Wu Yun. And these results will provide reference for the safer and better clinical utilization of kansui.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rubia cordifolia is a common traditional Chinese medicine that promotes blood circulation and eliminates blood stasis, and has been used to cure diseases related to blood stasis syndrome (BSS) clinically for many years. It has been previously demonstrated that anti-thrombosis and pro-angiogenesis can improve BSS. However, the anti-thrombotic and pro-angiogenic activities of Rubia cordifolia have not been well investigated. AIM OF STUDY To determine the potential anti-thrombotic and pro-angiogenic activities of Rubia cordifolia and to elucidate the underlying mechanisms. In addition, the major chemical constituents of Rubia cordifolia extract (QC) were qualitatively analysed by UPLC-Q-TOF/MS to explore the association between pharmacological activity and chemical constituents. MATERIAL AND METHODS The QC samples were composed of a 95% ethanol extract and an aqueous extract following extraction using 95% ethanol. UPLC-Q-TOF/MS was used to analyse the major chemical constituents of QC. For the anti-thrombotic experiment of QC, a phenylhydrazine (PHZ)-induced AB strain zebrafish thrombosis model was used. The zebrafish larvae were stained using O-dianisidine, and the heart and caudal vein of the zebrafish were observed and imaged with a fluorescence microscope. The staining intensity of erythrocytes in the heart (SI) of each group and the morphology of thrombus in the caudal vein were used to assess the anti-thrombotic effect of QC. For the pro-angiogenic assay of QC, the intersegmental blood vessel (ISV) insufficiency model of Tg(fli-1: EGFP)y1 transgenic zebrafish (Flik zebrafish), which was induced by the VEGF receptor tyrosine kinase inhibitor II (VRI), was used. The morphology of the intact ISVs and defective ISVs was observed to evaluate the pro-angiogenic activity of QC. The mechanism involved in promoting angiogenesis was studied with real-time PCR. RESULTS A total of 12 components in QC were identified based on standard compounds and references, including nine anthraquinones and three naphthoquinones. After treatment with QC, the PHZ-induced thrombosis in AB strain zebrafish larvae decreased to a certain degree, which we believe was related to its dosages, and the therapeutic effect within the 50-200 µg/mL QC treatment groups was especially prominent (P < 0.01, P < 0.001) compared to that in the PHZ model group. Similarly, QC also recovered the loss of the ISVs, which was induced by VRI in Flik zebrafish larvae, which have a certain dose-effect relationship. The pro-angiogenic activity of QC was also conspicuous (P < 0.01, P < 0.001) compared to that of the VRI model group. The following real-time PCR assay proved that QC significantly restored the VRI-induced downregulation of vWF, VEGF-A, kdrl, and flt-1 in Flik zebrafish (P < 0.05, P < 0.01, P < 0.001). CONCLUSIONS A total of 12 compounds from QC were analysed by UPLC-Q-TOF/MS. The data of the pharmacological experiments demonstrated that QC presented anti-thrombotic and pro-angiogenic activities in zebrafish, and the principal active components were likely anthraquinones and naphthoquinones. Thus, the current study provided a theoretical basis for the clinical use of Rubia cordifolia as a traditional Chinese medicine in promoting blood circulation and eliminating stasis.

Abstract
The embryos of model organism zebrafish were used to evaluate the acute toxicity of the extracts of Euphorbiae Pekinensis Radix and vinegar-processing Euphorbiae Pekinensis Radix, and the total terpene content of each extract was determined by using euphol as the reference standards. Twenty-four h normally developed zebrafish embryos were chosen, and 8 concentrations were adopted for each extract. Then the growth and death of zebrafish embryos were observed at 96 h after administration, and median lethal concentrations (LC50) of the different samples on zebrafish embryos were calculated. The results showed that all of the extracts (before and after vinegar processing) had acute toxicity on zebrafish embryos. The toxicity of vinegar-processing Euphorbiae Pekinensis Radix was significantly lower than that of crude Euphorbiae Pekinensis Radix. Among different extraction methods, ethanol extract was more poisonous than water extract; in different polarity fractions, the toxicity was in the following order: petroleum ether>dichloromethane>ethyl acetate>n-butyl alcohol and remaining part. Combined with the results of the determination of terpene components, it can be concluded that the terpenoids are the main toxic components of Euphorbiae Pekinensis Radix, positively correlated with toxicity degree. It indicates that the zebrafish embryo model is appropriate for the toxicity evaluation of Euphorbiae Pekinensis Radix and provides appropriate research methods and theoretical basis for the further study of the toxic components and the mechanism of reducing toxicity.

Abstract
Objective: To establish a Fisher discriminant model in order to predict the outcome of postoperative blood pressure for primary aldosteronism (PA). Methods: A total of 83 cases from the First Affiliated Hospital of Chongqing Medical University were enrolled and divided into two groups: cure group and not cure group according to postoperative blood pressure. Fisher stepwise discriminant analysis was used to establish a discriminant model, and compared with aldosteronoma resolution score (ARS) and nomogram model by receiver operating characteristic curve. Results: Hypertension was cured in 52 cases, and 31 cases remained uncured. Patients in uncured group were older, and had bigger body mass index (BMI), longer duration of hypertension, higher serum triglyceride (TG), more types of antihypertensive drug, higher incidence of diabetes, smoking and alcohol intake, less typical nodules on computed tomography imaging, lower estimated glomerular filtration rate (eGFR) and high density lipoprotein cholesterol. The discriminant model based on BMI, types of antihypertensive drugs, typical nodules on CT, eGFR and TG was established and the cut-off value was 0.195 9, with a sensitivity of 86.5% and a specificity of 83.9%. The area under the curve was 0.857 (95% CI: 0.764-0.951), which was higher than that of ARS (0.733, 95% CI: 0.619-0.847) and the nomogram model (0.735, 95% CI: 0.619-0.851). Conclusion: The Fisher discriminant model had a high value to predict the outcome of postoperative blood pressure in PA.

Abstract
OBJECTIVE To compare the difference of Euphorbia Pekinensis Radix before and after being processed with vinegar in the toxicity on rat small intestinal crypt epithelial cells IEC-6, and make a preliminary study on the mechanism of detoxication of Euphorbia Pekinensis Radix processed with vinegar. METHOD With rat small intestinal crypt epithelial cells IEC-6 as the study object, the MTT method was adopted to detect the effect of Euphorbia Pekinensis Radix before and after being processed with vinegar on IEC-6 cell activity. The morphology of cells were observed by the inverted microscope. The down-regulated mitochondrial apoptosis pathway of enterocytes caused by the vinegar processing was analyzed by using the high content screening. RESULT Compared with the negative control group, the proliferation inhibition experiment showed that Euphorbia Pekinensis Radix showed a relatively high intestinal cell toxicity (P < 0.01). The results of HCS analysis showed that Euphorbia Pekinensis Radix could significantly reduce the cell nucleus Hoechst fluorescence intensity and mitochondria membrane (P < 0.05, P < 0.01), and increase Annexin V-FITC and PI fluorescence intensity and membrane permeability (P < 0.01, P < 0.01, P < 0.01). After being processed with vinegar, compared with Euphorbia Pekinensis Radix groups with different doses, Euphorbia Pekinensis Radix processed with vinegar could significantly decrease the cell proliferation inhibition effect on enterocytes, increase the cell nuclear Hoechst fluorescence intensity and mitochondria membrane (P < 0.05, P < 0.05), and decrease Annexin V-FITC and PI fluorescence intensity and membrane permeability (P < 0.01, P < 0.01, P < 0.05), and showed a certain dose-effect relationship. CONCLUSION The vinegar processing can further reduce the toxicity of Euphorbia Pekinensis Radix on enterocytes. Its possible mechanism can decrease the effect of Euphorbia Pekinensis Radix on the permeability of IEC-6 cell membrane, so as to provide a basis for further explanation of the detoxication mechanism of Euphorbia Pekinensis Radix processed with vinegar.

Abstract
OBJECTIVE To discuss the effect of Kansui Radix prepared by different processes on cell cycle and apoptosis of normal human liver cell lines LO2. METHOD With normal human liver cell lines LO2 as the study object, the MTT method was adopted to study the effect of Kansui Radix prepared by different processes, including Kansui Radix, stir-baking Kansui Radix, Kansui Radix moistening with vinegar and Kansui prepared by different processes, on LO2 cell activity. The cellular morphological changes were observed by inverted microscope. The effect of Kansui Radix stir-baked with vinegar on LO2 cell cycle and apoptosis was observed by flow cytometry. RESULT Compared with the negative control group, Kansui could obviously inhibit the activity of human normal liver cell lines LO2 (P <0.01) , and significantly increase the percentage of LO2 cells in S phase (P <0.05) , notably decrease the percentage of LO2 cells in G2/M phase (P <0.01) , significantly increase the early apoptosis rate, late apoptosis rate and necrosis rate and total apoptosis rate of human normal liver cell lines LO2 (P <0.01). Compared with the Kansui group, all of the other processed Kansui samples could significantly decrease the cell proliferation inhibition (P <0.01) , and the trend of morphological degradation. Besides, they could significantly increase the percentage of LO2 cells in G2/M phase (P <0.05, P <0.05, P <0. 01) , significantly decrease the early apoptosis rate, late apoptosis rate and necrosis rate, and total apoptosis rate of human normal liver cell lines LO2 (P < 0.01). The order of the increase in the percentage of cells in G2/M phase and the decrease in apoptosis rate was Kansui Radix stirbaked with vinegar > Kansui Radix moistening with vinegar > stir-baking Kansui Radix. CONCLUSION The toxicity of processed Kansui could be reduced by affecting LO2 cell cycle and apoptosis. The processes of stir-baking and moistening with vinegar can play a synergistic effect in the detoxication of human normal liver cell lines LO2, which provides a basis for unveiling the rationality of stirbaking with vinegar of Kansui in the detoxication, as well as the optimizing the process.

Abstract
OBJECTIVE To compare the toxicity of Euphorbia pekinensis before and after being processed by vinegar on normal liver cells LO2, and discuss its possible mechanism. METHOD LO2 cells were cultured in vitro, and processed with different concentrations of crude and vinegar-processed E. pekinensis. MTT assay was used to measure the inhibitory effect of LO2 cell; Hoechst 33258 staining was used to observe the morphological changes in apoptosis cell; Annexin V-FITC flow cytometry was used to analyze the apoptotic rate of LO2 cell; PI staining flow cytometry was used to analyze its impact on cell cycle. The level or content of ALT, AST, LDH, SOD, MDA and GSH were observed as well. RESULT Compared with the negative control group, crude E. pekinensis at all concentrations could obviously inhibit LO2 cell proliferation, induce LO2 cell apoptosis and cause cell arrest in S phase, with significant differences (P <0.05). E. pekinensis could significantly increase the levels of ALT, AST and LDH (P <0.05) in the supernatant of cell culture fluid, significantly decrease the level of SOD and the content of GSH (P <0.05) , and significantly increase the content of MDA (P <0.05). Compared with the crude E. pekinensis group, E. pekinensis after being vinegar-processed can significantly reduce cell apoptotic rate, cell cycle arrest, activities of ALT, AST, LDH in the supernatant of cell culture fluid (P <0.05) , and remarkably increase the level of SOD and the content of GSH, but reduce the content of MDA in the supernatant of cell culture fluid. CONCLUSION Vinegar-processed E. pekinensis can release the cytotoxicity of LO2 cell. Its mechanism may be related to the decrease in the oxidative damage of LO2 cells, thereby reducing the cell cycle arrest and apoptosis.

Abstract
Cytochrome P450 (CYP) 2C19 metabolizes arachidonic acid to biologically active epoxyeicosatrienoic acids, which significantly promote proliferation of cancer cells in vitro and in vivo. We looked for a possible association between human CYP2C19*3 gene polymorphism and breast cancer in the Chinese Han population. In a Chinese Han case-control study of breast cancer patients (N = 600) and age- and gender-matched healthy controls (N = 600), we investigated polymorphism in the CYP2C19 gene by PCR-RFLP analysis. The CYP2C19*3 AG + AA genotype was significantly more prevalent in breast cancer patients than in control subjects (6.67 vs 3.00%; P = 0.003). The odds ratio for carriers of AG + AA genotype for breast cancer was 2.31 (95% confidence interval = 1.27-4.43). Among patients, estrogen receptor, tumor size, histologic grade, presence of primary lymphonode metastases, progesterone receptor positivity, and age at diagnosis were not found to be significantly associated with CYP2C19*3 genotypes (all P > 0.05). We conclude that the CYP2C19*3 gene polymorphism is associated with breast cancer risk in Chinese Han women.

Abstract
Based on anatomical and dye injection observations, since 1984 42 cases of hand tissue defects (due to injury or surgery) have been reconstructed using a reverse flow unlar artery forearm island flap. Of the 42 cases, aetiology has included extensive crushing (25 cases), electric saw injuries (7 cases), burn scars (4 cases) and tissue defects following tumour or chronic ulcer resection (6 cases). Only one flap developed necrosis. The survival rate was 97.6%, including 4 cases of distal marginal necrosis. This procedure, therefore, offers a useful alternative in the repair and reconstruction of extensive tissue defects in the hand, whether caused by accidental injury or by surgery.
