RESUMO
To analyze the outcome indicators from the randomized controlled trials(RCTs) on traditional Chinese medicine(TCM) treatment for diabetic foot, and to lay a foundation for the establishment of the core index set of the clinical trials on TCM treatment of diabetic foot. Computer retrieval of RCTs on TCM treatment of diabetic foot was performed in CNKI, Wanfang, SinoMed, PubMed, Cochrane Library, EMbase and Web of Science databases. Literature screening and data extraction were conducted independently by two researchers in strict accordance with inclusion and exclusion criteria. Any difference was resolved through discussion. A total of 72 RCTs involving 5 791 patients were included and 204 indicators were used. The number of indicators used in a single study was 2-22, with an average of 3 indicators used for each RCT. The indicators with top 16 frequency were clinical total effective rate, ankle brachial index(ABI), ulcer area, TCM syndrome integral, fibrinogen(FIB), fasting blood glucose(FBG), plasma viscosity(PV), c-reactive protein(CRP), saccharification blood of eggs(HbAlc), 2 h postprandial blood glucose(2 hPG), wound healing time, triglyce-rides(TC), TCM efficacy for syndromes, total cholesterol(TG), percutaneous oxygen partial pressure(TCPO2) and TCM symptom scores. The difference in selection of RCT indicators was large among TCM treatment methods for diabetic foot, and the combination of outcome indicators was arbitrary. The description on indexes was not standardized. Some non-laboratory examination indicators, some indicators not recommended in guidelines or not recognized in clinical practice, and some self-made indicators were not explained in detail. There was a lack of standardized evaluation criteria for indicators. The indicators had large time-point difference in measurement, and the time points were not distinguished in the measurement for diabetic foot patients with different degrees of severity. In addition, the patients with long course of treatment weren't timely measured. The characteristics of TCM or significant endpoint indicators were insufficient. It was urgent to establish the core index set of TCM in treating diabetic foot.

To systemically evaluate the efficacy and safety of Gingko Ketone Ester Dropping Pills in treating angina pectoris and co-ronary heart disease. CNKI, Wanfang, SinoMed, PubMed, Cochrane Library and EMbase databases were retrieved on computer, and the randomized clinical trial(RCT) on Gingko Ketone Ester Dropping Pills in treating angina pectoris and coronary heart disease, which were published from the database establishment to December 31, 2019, were comprehensively collected. Literature screening, data extraction and quality evaluation were conducted independently by two researchers according to inclusion and exclusion criteria. Literature methodology quality evaluation was conducted with use of the Cochrane Handbook 5.3.0(bias risk assessment tool). Meta-analysis was performed with RevMan 5.3.0 software. A total of 10 RCTs were included. The results of the Meta-analysis showed that as compared with conventional Western medicine alone, the application of Gingko Ketone Ester Dropping Pills combined with conventional Western medicine treatment further improved the total effective rate and electrocardiogram effect(RR=1.43,95%CI[1.20,1.71],P<0.000 1). There were statistically significant differences in the number of angina attacks, the duration of angina and the amount of nitroglycerin used. In terms of safety indicators, four studies reported adverse reactions in the experimental group, including facial flu-shing, tachycardia, dizziness, dyspnea, nausea and other symptoms. Based on the existing findings, in the treatment of angina pectoris and coronary heart disease, Gingko Ketone Ester Dropping Pills combined with conventional Western medicine can improve the clinical total effective rate, electrocardiogram effect, number of angina attacks, duration of angina and the amount of nitroglycerin used. However, in the included studies, due to some methodological quality problems which would impact the reliability of literature results more high-quality randomized controlled trials are still needed for further verification.

This study aimed to comprehensively analyze and compare the differences of different clinical study types currently published in the safety evaluation of Xuebijing Injection. Six databases, namely the Cochrane Library, PubMed, EMbase, CNKI, VIP and Wanfang database, were electronically retrieved to collect all types of studies on the safety of Xuebijing Injection, including randomized controlled trials, case-controlled studies, cohort studies, systematic reviews, and centralized monitoring studies of clinical safety(hospital), in order to comprehensively and objectively evaluate the safety of Xuebijing Injection, and analyze the differences of different research results. A total of 211 literatures were included, involving a total of 46 384 patients treated with Xuebijing Injection, and 423 adverse reactions(ADRs) occurred. They included 191 randomized controlled trials, 3 cohort studies, 15 systematic reviews, and 2 centralized monitoring studies of clinical safety(hospital), and the incidence of adverse reactions was 2.54%(common), 2.31%(common), 0.95%(occasionally), and 0.50%(occasionally). More than half of the 423 cases of ADRs occurred in skin and adnexal system(151 cases) and gastrointestinal system(65 cases), including such manifestations as rash, skin itching, nausea and vomiting, diarrhea. The degree of ADRs was mild. Randomized controlled trials showed that the incidence of ADR was the highest when Xuebijing Injection was used for malignant tumor and multiple organ failure. And the systematic evaluation showed that the incidence of ADR was the highest when Xuebijing Injection was used for spontaneous peritonitis of liver cirrhosis. In conclusion, different study types could lead to significant differences in the results of drug safety evaluation. Sample size, study type, and quality control are the main factors for biased results. Due to large sample size and high-quality, centralized monitoring studies become the better clinical safety evaluation model of drugs at present, and full life cycle management could more objectively reflect drug safety and guide clinical rational drug use.

To evaluate the efficacy and safety of Compound Danshen Injection combined with Western medicine in the treatment of vascular dementia. Databases of Cochrane Library, PubMed, EMbase, CNKI, SinoMed, VIP, Wanfang Data were electronically retrieved for collecting randomized controlled trial(RCT)about vascular dementia treated with Western medicine alone or combined with Compound Danshen Injection from the year of database establishment to January 2020. Two researchers independently screened out li-teratures, extracted data, and evaluated the risk of bias for inclusion in the study. Meta-analysis was conducted using RevMan 5.3 software. A total of 5 RCTs were included, involving 588 patients, with 299 in treatment group and 289 in control group. Meta-analysis results showed that compared with Western medicine alone, Compound Danshen Injection combined with Western medicine was better in the effective rate(RR=1.23,95%CI[1.14,1.33],P<0.000 01), MMSE score(MD=3.54,95%CI[3.01,4.06],P<0.000 01), ADL score(MD=11.49,95%CI[8.05,14.93],P<0.000 01), the level of CRP(MD=-0.72,95%CI[-1.25,-0.20],P=0.007) and the level of IL-6(MD=-7.64,95%CI[-9.65,-5.63],P<0.000 01). Adverse reactions mainly included rash and skin prick, which did not affect the treatment effect. Based on the findings, the combination of Compound Danshen Injection in the treatment of vascular dementia could improve the effective rates, relieve the mental state damage and improve the daily living ability, with mild adverse reactions and a low incidence. However, due to the low quality of the included literatures, high-quality and large-scale randomized controlled trials are needed for further verification.

BACKGROUND: The relationship between chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and erectile dysfunction (ED) has been shown in many studies. However, the specific mechanism remains unclear. This study was to investigate the corpus cavernosum smooth muscle cell function and phenotype transformation in Experimental autoimmune prostatitis (EAP) rats. METHODS: EAP was induced in rats by using prostate protein supplemented with immuneadjuvant extraction, and the max-ICP and MAP were measured. IHC and Masson staining were done to assess inflammatory infiltration and collagen deposition in the corpus cavernosum, respectively. Subsequently, normal rat and EAP rat CCSMCs were purified by tissue block implantation and differential adherence method. The oxidative stress, smooth muscle phenotype transformation, cell cycle and intracellular calcium ion transport were also evaluated. RESULTS: The ratio of max ICP/MAP in EAP rats significantly reduced, and the TNF-α content and collagen deposition in the corpus cavernosum markedly increased as compared to healthy rats. High-purity rat CCSMCs were obtained. Oxidative stress was evident and the cGMP content decreased in the EAP rat CCSMCs. The expression of Cav1.2, IP3R1 and RyR2 increased, but the SERCA2 expression decreased in EAP rat CCSMCs, which was accompanied by increased intracellular calcium. Increased expression of OPN, collagen and KCa3.1, decreased Calponin expression and increased proportion of cells in the S phase were also observed in the EAP rat CCSMCs. CONCLUSION: CP causes oxidative stress and imbalance of intracellular calcium in CCSMCs and promotes CCSMCs transformation from contractile to synthetic state, which may be involved in the pathogenesis of ED.
RESUMO
Objective: To evaluate the efficacy and safety of picosecond (ps) 755-nm alexandrite laser with a diffractive lens array (DLA) generating laser-induced optical breakdown, which may be beneficial for melasma treatment. Background: Melasma is notorious for difficult to treat with any modality setting. Recently, picosecond alexandrite laser with DLA seems promising for dealing with it without intolerable complications. Methods: Twenty (N = 20) Asian female melasma patients with Fitzpatrick skin type IV were recruited for 3 treatment sessions of picosecond 755-nm alexandrite laser with DLA at a 4- to 6-week interval. The pulse duration was 750 ps. An 8-mm spot size and the fluence of 0.4 J/cm2 was used over the target area with 2 passes per treatment area and around 2000-2500 passes in total. The repetition rate was 10 Hz. Melasma Area and Severity Index (MASI) score and VISIA® imaging system analysis were utilized for evaluation before treatment and 4 weeks after the completion of the third treatment session. The clinical improvement and adverse events were assessed by the physicians and patients, respectively. Results: The median age of the patients was 45 years (from 27 to 55 years). In the physicians' evaluation, 40% (n = 8) of patients showed good improvement and 40% (n = 8) of patients showed moderate improvement. The mean MASI score before and after laser therapy showed significant improvement from 9.0 ± 4.8 to 6.5 ± 3.7 (p < 0.001). VISIA analysis of the forehead presented significant improvement in spots (p = 0.007) and porphyrins (p = 0.032). Some patients experienced erythema (25%), pruritus (20%), and scaling (20%) but subsided within few days of using emollients and sunscreen. Only 5% (n = 1) of patients developed mild postinflammatory hyperpigmentation, which also subsided in 3 weeks. Conclusions: Three sessions of picosecond 755-nm alexandrite laser with a DLA were effective for melasma treatment in Asian patients with minimal side effects.

The relative randomized controlled trials( RCTs) of Yiqi Huoxue Chinese patent medicine for coronary heart disease with angina pectoris were retrieved from China National Knowledge Infrastructure( CNKI),Wan Fang,VIP and Chinese Biomedical Literature Database( CBM) in July 2018. Two researchers independently completed the literature screening,data extraction and quality evaluation according to the pre-determined inclusion and exclusion criteria,and the results were cross-checked.The data were analyzed by Win Bugs,and STATA software was used for plotting. Finally,114 RCTs were included,involving 7 Yiqi Huoxue Chinese patent medicines and 11 775 patients. Network Meta-analysis showed that the total effective rate for improvement in AP symptoms had 7 direct comparisons and 21 indirect comparisons,8 of which were statistically significant. The ECG improvement had 7 direct comparisons and 21 indirect comparisons,7 of which were statistically significant. In terms of the total effective rate of improvement in AP symptoms,the order of efficacy was as follows: Shensong Yangxin Capsules > Shexiang Baoxin Pills > Qishen Yiqi Dropping Pills > Tongxinluo Capsules > Wenxin Granules > Qishen Capsules > Naoxintong Capsules. In terms of ECG improvement,the order of efficacy was as follows: Shexiang Baoxin Pills > Tongxinluo Capsules > Naoxintong Capsules > Qishen Yiqi Dropping Pills> Wenxin Granules > Shensong Yangxin Capsules > Qishen Capsules. The results showed that Shensong Yangxin Capsules and Shexiang Baoxin Pills had certain advantages in the treatment of coronary heart disease with angina pectoris. Due to the small sample size,more studies were required to further verify the evidences.

Increasing evidence suggests that inflammation is related to the pathophysiology of depression. Curcumin (CUR), which is a natural component extracted from the rhizome of Curcuma longa, seems to be efficacious in depression treatment. Hence, the present study aims to explore whether the anti-depressive effect of curcumin is connected to its anti-inflammatory features. Twenty-one SD rats were randomly divided into three groups, namely, control, CUMS (chronic unpredictable mild stress), and CUMSâ¯+â¯CUR. After stress exposure for four weeks, the CUMS group showed depressive-like behaviors, and the curcumin treatment successfully corrected the depressive-like behaviors in stressed rats. Additionally, the curcumin could effectively decrease mRNA expression of proinflammatory cytokines (IL-1ß, IL-6, and TNF-α) and suppress NF-κB activation. Curcumin also inhibited the stressed-induced P2X7R/NLRP3 inflammasome axis activation, along with the reduced transformation of pro-IL-1ß to mature IL-1ß. The stress-induced activation of indolamine-2, 3-dioxygenase (IDO) and an increased kynurenine/tryptophan ratio were also ameliorated by curcumin supplementation. In conclusion, the study revealed that curcumin relieves a depressive-like state through the inhibition of the NLRP3 inflammasome and kynurenine pathway.

OBJECTIVE: To investigate the therapeutic effects and mechanisms of Salvia miltiorrhizae (Danshen) in the treatment of severe acute pancreatitis (SAP)- or obstructive jaundice (OJ)-induced heart injury. METHODS: A total of 288 rats were used for SAP- (n=108) and OJ-associated (n=180) experiments. The rats were randomly divided into sham-operated, model control, and Salvia miltiorrhizae-treated groups. According to the difference of time points after operation, SAP rats in each group were subdivided into 3, 6 and 12 h subgroups (n=12), whereas OJ rats were subdivided into 7, 14, 21, and 28 d subgroups (n=15). At the corresponding time points after operation, the mortality rates of the rats, the contents of endotoxin and phospholipase A2 (PLA2) in blood, and pathological changes of the hearts were investigated. RESULTS: The numbers of dead SAP and OJ rats in the treated groups declined as compared with those in the model control group, but not significantly (P>0.05). The contents of endotoxin (at 6 and 12 h in SAP rats and on 7, 14, 21, and 28 d in OJ rats, respectively) and PLA2 (at 6 and 12 h in SAP rats and on 28 d in OJ rats, respectively) in the treated group were significantly lower than those in the model control group (P<0.01 and P<0.001, respectively). Besides, myocardial pathological injuries were mitigated in SAP and OJ rats. CONCLUSION: In this study, we found that Salvia miltiorrhizae improved myocardial pathological changes, reduced the content of PLA2 in blood, and decreased the mortality rates of SAP and OJ rats, exerting protective effects on the hearts of the rats.

BACKGROUND: The good therapeutic effects of large dose of dexamethasone on severe acute pancreatitis (SAP) patients have been proved. This study was designed to investigate the influence of dexamethasone on apoptosis of acinar cells in the pancreas of rats with SAP and the protein expression of the apoptosis-regulating genes Bax and Bcl-2. METHODS: Ninety Sprague-Dawley rats with SAP were randomly divided into a model group and a dexamethasone treated group (45 rats in each group), and another 45 rats formed the sham operation group. Survival rates were calculated and gross pathological changes in the pancreas of each group were observed under a light microscope 3, 6 and 12 hours after operation. Tissue microarray technology was applied to prepare pancreatic tissue sections. The changes in Bax and Bcl-2 protein expression levels of pancreatic tissues from each group were assessed by immunohistochemical staining, and TUNEL staining was used to evaluate changes in apoptosis index. RESULTS: The model and treated groups did not differ in mortality at each time point. The pathological score for the pancreas in the treated group was significantly lower than that in the model group at 3 and 6 hours. The positive rates of Bax protein expression in the head and tail of the pancreas in the treated group at all time points were all markedly higher than those of the model group. The positive rate of Bcl-2 protein expression in the head of the pancreas in the treated group was significantly higher than that of the model group at 3 hours. TUNEL staining showed that the pancreas head and tail apoptosis indices of the treated group were markedly higher than those of the model group after 6 hours. CONCLUSIONS: Apoptosis may be a protective response to pancreatic cell injury. The mechanism of action of dexamethasone in treating SAP may be related to the apoptosis of acinar cells in the pancreas induced by apoptosis-regulating genes such as Bax and Bcl-2. The advantages of tissue microarrays in pathological examination of the pancreas include saving of time and energy, efficiency and highly representative.
