ABSTRACT
OBJECTIVES@#To detect the contents of Tangwei capsule main components with high performance liquid chromatography-quantitative analysis of multicomponents by single marker (HPLC-QAMS) method and to evaluate the quality with chemometrics and entropy weight-technique for order preference by similarity to an ideal solution (EW-TOPSIS).@*METHODS@#A symmetry C18 column and 0.1% formic acid-acetonitrile as mobile phase were used for HPLC of Tangwei capsule. The contents of 3'-hydroxypuerarin, puerarin, 3'-methoxypuerarin, methylnissolin-3-O-glucoside, calycosin, formononetin, rosmarinic acid, salvianolic acid B, dihydrotanshinone Ⅰ, cryptotanshinone, tanshinone Ⅰ, tanshinone ⅡA and cucurbitacin B in 15 batches of Tangwei capsule were determined simultaneously. The quality differences of 15 batches of samples were analyzed by chemometrics and EW-TOPSIS.@*RESULTS@#The HPLC-UV showed that 13 components had good linear relationships in corresponding concentration ranges (r≥0.9991). The relative standard deviations (RSD) of precision, repeatability and stability were all less than 2.00%. The average recovery rates were between 96.86% and 100.13%, and RSD were all less than 2.00%. Cluster analysis showed that 15 batches of samples were clustered into 3 groups. Partial least squares-discriminant analysis showed that salvianolic acid B, formononetin, puerarin, 3'-methoxypuerarin and rosmarinic acid were the main potential markers affecting the quality of Tangwei capsule. EW-TOPSIS analysis showed that the quality of S12-S15 was superior.@*CONCLUSIONS@#The analytical method established in this study can be used for the comprehensive evaluation of the quality of Tangwei capsule to provide laboratory support for its quality control and overall evaluation.

In the context of the reform of group payment related to disease diagnosis, a tertiary first-class hospital focused on the needs of patients and guided by value-based healthcare, established a professional and normalized refined anti-tumor drug management system, setted up a multidisciplinary diagnosis and treatment team, and promoted " Internet plus pharmaceutical services" in December 2018.From 2019 to 2021, the proportion of hospital drugs were 30.8%, 30.1%, and 27.3%, respectively. The amount of money spent on anti-tumor drugs were 83.25 million yuan, 76.41 million yuan, and 62.48 million yuan, respectively, showing a decreasing trend year by year. The practice of refined management of anti-tumor drugs fully reflected the core concept of value based healthcare, achieving closed-loop management of the entire process of drugs, improving the level of rational drug use, reducing the economic burden on patients, and providing reference for improving the level of rational use of anti-tumor drugs in public hospitals.
ABSTRACT
Objective: To observe the effects of acupuncture plus spinal manipulations on the physical functioning and levels of alkaline phosphatase (ALP), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and osteoprotegerin (OPG) in patients with ankylosing spondylitis (AS). Methods: A total of 128 AS cases were allocated into a control group and an observation group using random number table method, with 64 cases in each group. Patients in both groups took sulfasalazine and meloxicam. Patients in the observation group received additional acupuncture plus spinal manipulations. The efficacy, Bath AS functional index (BASFI), Bath AS disease activity index (BASDAI), and the levels of ALP, ESR, CRP and OPG were compared between the two groups after eight weeks of treatment. Results: After treatment, the symptom scores of traditional Chinese medicine in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); the VAS, BASFI and BASDAI scores in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); and the ALP, ESR, CRP and OPG levels in both groups were decreased (all P<0.05), and these levels in the observation group were significantly lower than in the control group (all P<0.05). The total efficacy rate was 92.2％ in the observation group, versus 78.1％ in the control group, presenting a statistical significance (P<0.05). Conclusion: Conventional medication combined with acupuncture and spinal manipulations can improve clinical symptoms, accelerate the recovery of physical functioning, and reduce the ALP, ESR, CRP and OPG levels.
ABSTRACT
Objective:To investigate the expression of Pyruvate dehydrogenase kinase 1(PDK1), phosphorylated Pyruvate dehydrogenase (p-PDH) and Pyruvate kinase isozyme type M2 (PKM2) based on Warburg effect pathway in cervical cancer tissues, and explore the roles of these molecules on prognosis and recurrence after postoperative radiation.Methods:The expressions of PDK1, p-PDH and PKM2 in primary tissues of 102 patients with cervical cancer were detected by immunohistochemistry, including 63 patients receiving postoperative radiation. The expression of the three molecules on prognosis and the efficacy of postoperative radiation on cervical cancer were analyzed separately and corporately.The level of mRNA were verified by using the 300 patients from GEO database. Kaplan-Meier method and COX proportional hazards regression model were used for univariate and multivariate analysis.Results:High expression of PDK1 and all the three indicators (PDK1 high/p-PDH high/PKM2 high) were positively correlated with pelvic lymphnode metastasis ( χ2=10.890, 7.407, P<0.05). PDK1 high/p-PDH high/PKM2 high, Federation International of Gynecology and Obstetrics (FIGO) staging, pelvic lymph node metastasis and postoperative radiation could affect the overall survival (OS) and disease-free survival (DFS) ( P<0.05). Multivariate analysis showed that PDK1 high /PDH high/PKM2 high, FIGO staging and postoperative radiation were the independent prognosis factors for OS and DFS( P<0.05). The verification result of the GEO dataset showed that PDK1 high/PDH high/PKM2 high was the risk factor for DFS( P<0.05). Pathological type, pelvic lymph node metastasis and PDK1 high/p-PDH high/PKM2 high could affect the DFS of those patients with postoperative radiation ( P<0.05). In addition, the multivariate analysis showed that pathological type and PDK1 high /p-PDH high/PKM2 high were the independent prognosis factors for DFS( P<0.05). Conclusions:The patients of PDK1 high /p-PDH high/PKM2 high phenotype have poor prognosis and DFS with postoperative radiation, which may be a high-risk group with poor prognosis and high recurrence rate after postoperative radiotherapy of stageⅠ-Ⅱ B cervical cancer.This study provides a novel strategy for stratified treatment of cervical cancer.

ABSTRACT
Primitive mammalian heart transforms from a single tube to a four-chambered muscular organ during a short developmental window. We found that knocking out global microRNA by deleting Dgcr8 microprocessor in Mesp1 cardiovascular progenitor cells lead to the formation of extremely dilated and enlarged heart due to defective cardiomyocyte (CM) differentiation. Transcriptome analysis revealed unusual upregulation of vascular gene expression in Dgcr8 cKO hearts. Single cell RNA sequencing study further confirmed the increase of angiogenesis genes in single Dgcr8 cKO CM. We also performed global microRNA profiling of E9.5 heart for the first time, and identified that miR-541 was transiently highly expressed in E9.5 hearts. Interestingly, introducing miR-541 back into microRNA-free CMs partially rescued their defects, downregulated angiogenesis genes and significantly upregulated cardiac genes. Moreover, miR-541 can target Ctgf and inhibit endothelial function. Our results suggest that microRNAs are required to suppress abnormal angiogenesis gene program to maintain CM differentiation.

ABSTRACT
Objective@#To investigate the expression of DNA damage repair factor PDZ binding kinase (PBK) and matrix metalloproteinase 9 (MMP-9) in cervical cancer and the effect on clinical outcomes of concurrent chemoradiotherapy.@*Methods@#A total of 65 cervical cancer pathological specimens were collected from January 2014 to July 2016. Immunohistochemistry was used to detect PBK and MMP-9 expression in the specimens.External irrsdeation was treated with intensity-modulated radiation therapy at a dose of 50 Gy/25 F. After 18 times of external irradiation, high-dose rate postoperative treatment was giver at a dose of 30-36 Gy/5-6 F which lasts 3-4 weeks. Weekly chemotherapy with Cisplatin(DDP) begins simultaneously at the beginning of external irradiation. DDP was administered intravenously at a dosage of 40 mg/m2 for 2 to 6 week. All patients were followed-up as routine. The relationship between clinical characteristics and prognosis of patients and the expression of PBK and MMP-9 were analyzed.@*Results@#PBK was expressed in 92.3% of tissues and MMP-9 was expressed in 69.2% of tissues. The expression of PBK was positively associated with overall survival (OS) and disease progression-free survival (PFS) of cervical cancer patients (χ2=4.324, 8.068, P<0.05). The expression of MMP-9 was related with PFS (χ2=5.134, P<0.05). Patients with PBK and MMP-9 expression suffered poor OS and PFS (χ2=5.382, 9.364, P<0.05).@*Conclusions@#PBK and MMP-9 could be a biomarker to predict the prognosis of cervical cancer.
ABSTRACT
The raw and processed roots of Plygonum multiflorum Thunb (PM) are used to treat different diseases in clinical practice. In order to clarify the influence of processing, a comparative study of chemical substance analysis was carried out. As the xenobiotics with a high enough exposure in target organs being considered as the potential effective or toxicity components, an in vivo study was also implemented to characterize the constitutes and metabolites, and meanwhile, the factor of compatibility with black bean were also considered. As a result, a total of 148 compounds were detected in PM extracts and more than 40 compounds were only detected in the processed products, which were probably new components produced during the steaming process. In in vivo study, 7 prototype components and 66 metabolites were detected or tentatively identified, 24 of which were reported for the first time. Our results indicated that processing greatly changed the chemical composition of PM and influenced the disposition of the compounds in vivo. To the best of our knowledge, this was the first global comparative study of raw and processed PM. These results expanded our knowledge about the influence of processing of PM and provided the essential data for further efficacy or toxicity studies.

Conclusion Electroacupuncture at "Baihui"and "Zusanli" acupoints can decrease the contents of TNF-α, IL-1 and IL-6 in the cortex of VCI rats, and improve the learning and memory ability of rats.
ABSTRACT
Objective To explore the clinical value of uncinate process resection combined with portalsuperior mesenteric vein resection and end-to-end anastomosis in distal pancreatectomy.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 11 patients who underwent distal pancreatectomy combined with portal-superior mesenteric vein resection and end-to-end anastomosis in the Peking University Cancer Hospital (8 patients) and Jilin Guowen Hospital (3 patients) between January 2014 to April 2018 were collected.During the vascular reconstruction,uncinate process of the pancreas was first resected for reducing anastomotic tension,and then end-to-end anastomosis was done after portal-superior mesenteric vein resection.Observation indicators:(1) intraoperative situations;(2) postoperative recovery situations;(3) postoperative pathological examination situations;(4) follow-up and survival situations.Follow-up using outpatient examination and imaging examination was performed to detect patients' postoperative survival,tumor recurrence and metastasis and postoperative venous anastomotic patency up to May 2018.Measurement data with normal distribution were represented as x±s.Measurement data with skewed distribution were described as M (range).The non-recurrence and non-metastasis survival curve,overall survival curve and survival rate were respectively drawn and calculated by the Kaplan-Meier method.Results (1) Intraoperative situations:11 patients received uncinate process resection of the pancreas,and successfully underwent distal pancreatectomy combined with portal-superior mesenteric vein resection and end-to-end anastomosis.Eight patients underwent distal pancreatectomy + Appleby combined with celiac axis resection due to pancreatic tumor involving common hepatic artery,including 2 undergoing combined total gastrectomy due to gastric ischemia;2 patients underwent distal pancreatectomy;1 patient underwent distal pancreatectomy + distal gastrectomy due to blood supply obstacle of distal stomach.Operation time and volume of intraoperative blood loss of 11 patients were (5.8± 1.1) hours and 800 mL (range,200-2 500 mL).(2) Postoperative recovery situations:there was no grade C of pancreatic fistula of 11 patients.Four patients had grade B of pancreatic fistula,including 2 were cured by drainage-tube indwelling of pancreatic wound ＞ 3 weeks,1 was cured by continous washing due to pancreatic fistula combined with infection,and 1 was cured by the second abdominal puncture drainage due to pancreatic fistula with fever;1 of 4 patients was combined with grade C of delayed gastric emptying and cured by conservative treatment,and other 3 patients didn't occur postoperative complications.Of 5 patients diagnosed as biochemical fistula,1 had esophagus-jejunum anastomotic leakage,and 1 had changes of hepatic ischemia in S2,S3 and S4b segments by CT examination and recovered normal liver function at 2 weeks postoperatively,with long-term hepatatrophia in S2 and S3 segments.There was no postoperative death and reoperation in 11 patients.Duration of postoperative hospital stay of 11 patients was (22± 5) days.(3) Postoperative pathological examination results:tumors of 11 patients were located in neck and body of the pancreas,with a maximum diameter of (4.8± 1.7)cm.Among 11 patients,10 were confirmed with moderate-or low-differentiated ductal adenocarcinoma and 1 with anaplastic carcinoma.The length of portal-superior mesenteric vein resection of 11 patients was (2.6± 0.8) cm.Seven of 11 patients occurred different degrees of tumor infiltration in the portal-superior mesenteric vein,and other 4 patients occurred inflammatory adhesion,without tumor infiltration.(4) Follow-up and survival situations:11 patients were followed up for 3.0-37.6 months,with a median time of 15.7 months.During the follow-up,8 patients died of tumor recurrence and /or metastasis,and 3 survived;the non-recurrence and non-metastais survival time and overall survival time were respectively 9.0 months (range,3.0-37.6 months) and 24.6 months (range,3.0-37.6 months).One patient was complicated with anastomotic stenosis and surrounding varices of portal-superior mesenteric vein by postoperative half-year reexamination,anastomotic vein anomalies and venous thrombosis were not found in other patients before local tumor recurrence and / or death.Conclusion The combined uncinate process resection of the pancreas cannot increase the risk of postoperative pancreatic fistula,and it could effectively reduce the anastomotic tension in the distal pancreatectomy combined with portal-superior mesenteric vein resection and reconstruction,meanwhile,it can also achieve end-to-end anastomosis after longer vein resection.
ABSTRACT
BACKGROUND: Embryonic stem cells are pluripotent stem cells that can differentiate into all cell types and propagate themselves indefinitely in vitro, which have been used widely in biological research. OBJECTIVE: To summarize the culture methods of embryonic stem cells in vitro, as well as the significance, methods, clinical applications of embryonic stem cells as genetic disease models. METHODS: Relevant articles were searched in PubMed using the key words of "embryonic stem cell, genetic diseases" which appeared in the titles and abstracts. The latest articles were preferred. Totally 43 eligible articles were obtained for result analysis. RESULTS AND CONCLUSION: In the genetics study, embryonic stem cells have been widely used to construct monogenic and chromosome disease models, which can make up the limitations of animal and cell models. Models constructed by embryonic stem cells are conducive to the investigations on pathological processes and molecular mechanisms of genetic diseases. But there are also some ethic disputes on the use of embryonic stem cells, which need further studies.
ABSTRACT
Objective: This study was conducted to determine the proper percentage of EN in the total energy and nutrition support for critically ill patients with traumatic brain injury (TBIs). Methods: 94 cases were randomly divided into 3 groups according to the percentage of EN in the total energy: 100％ EN group in which patients received 100％ calories from EN; 75％ EN group in which patients received 75％ calories from EN, 25％ from PN; 50％ EN group in which patients received 50％ calories fromm EN, 50％ from PN. At baseline and follow-up on day 4, 7, 10, nutrition parameters, complete blood count and electrolytes as well as metabolic parameters including tests of liver and renal function were measured. Complications during treatment were recorded and the prognosis was finally judged. Results: Total protein and albumin were significantly higher in the 50％ EN and 75％ EN group on day 7 than in TEN group (P＜ 0. 05). There was significance difference found in complications between 75％EN and 50％EN group. A reduction in the length of stay in the hospital and expenses in the ICU for 10 days in the 75％ EN group (P ＜ 0. 05) was also observed. Conclusion: 75％ calories from EN in the total energy and nutrition support appeared to have great impact on management of critically ill patients with traumatic brain injury.

ABSTRACT
The aim of this study was to systematically review the efficacy and safety of iodine-125 brachytherapy combined with chemotherapy in patients with advanced lung cancer. PubMed, MEDLINE, EBSCO, FMJS and Web of Science were searched to obtain randomized controlled trials [RCTs], published in English and Chinese, until February 2016. The evaluating indicators were complete response [CR], partial response [PR], stable disease [SD], progressive disease [PD], overall response rate [ORR], disease control rate [DCR], one-year overall survival, two-year overall survival and adverse events. Revman 5.2 software was used for data syntheses and analyses. A total of 296 patients enrolled in 5 RCTs were ultimately included in this study based on our selection criteria, and 150 patients received chemotherapy alone, while another 146 patients received the combination therapy of iodine-125 brachytherapy and chemotherapy. The results showed that iodine-125 brachytherapy combined with chemotherapy was superior to chemotherapy alone in CR [risk ratio [RR] = 3.66, 95% confidence interval [CI]: 2.08 to 6.44, p<0.001], PR [RR = 1.47, 95% CI: 1.16 to 1.86, p=0.001], ORR [RR = 1.85, 95% CI: 1.54 to 2.22, p<0.001], DCR [RR = 1.19, 95% CI: 1.10 to 1.29, p<0.001], one-year overall survival [RR = 1.46, 95% CI: 1.12 to 1.92, p=0.006] and PD [RR = 0.20, 95% CI: 0.09 to 0.43, p<0.001]; meanwhile, there was no significant difference in two-year overall survival [RR = 1.30, 95% CI: 0.72 to 2.37, p=0.39]. In terms of adverse events, the combination therapy significantly increased the incidence of pneumothorax [RR = 4.93, 95% CI: 1.94 to 12.55, p=<0.001]; however, no significant differences were found in the incidence of other adverse events. This study indicated that the combination therapy of iodine-125 brachytherapy and chemotherapy could improve the therapeutic efficacy of advanced lung cancer without increasing the incidence of adverse events, except pneumothorax
