ABSTRACT

To systematically evaluate the clinical efficacy and safety of Ginkgo Leaf Tablets(GLT) in the treatment of acute cerebral infarction(ACI). Seven databases both at home and abroad were systematically retrieved from their establishment to March 2020. The data of the included studies were extracted after review and screening. The quality of the included studies was assessed with the Cochrane risk bias assessment tool, and then the included studies were put into Meta-analysis by RevMan 5.3 to evaluate the total cli-nical efficiency, neurological function score, blood lipids and incidence of adverse reactions in treatment of ACI by GLT. Finally, the GRADE system was adopted to evaluate the evidence quality of each outcome indicator and form recommendations. Ten studies involving 886 participants were included, all of which were of low quality. Meta-analysis results showed that,(1)in terms of the total clinical efficiency, GLT+Western medicine was superior to Western medicine alone(RR_(NDS)=1.20, 95%CI[1.06, 1.36], P=0.005; RR_(NIHSS)=1.35, 95%CI[1.09, 1.69], P=0.007), and there was no statistical difference between GLT+Xuesaitong Injection+Wes-tern medicine and Xuesaitong Injection+Western medicine(RR=1.16, 95%CI[1.00, 1.35], P=0.05).(2)In terms of improving neurological function score, GLT+Western medicine was superior to Western medicine alone(MD_(NIHSS[moderate(severe)])=-1.55, 95%CI[-2.22,-0.88], P<0.000 01; MD_(NIHSS(severe))=-7.51, 95%CI[-8.00,-7.02], P<0.000 01; MD_(NDS)=-1.36, 95%CI[-2.39,-0.33], P=0.01), and GLT+Danshen Injection+Western medicine was superior to Danshen Injection+Western medicine(MD_(NDS)=-3.09, 95%CI[-3.84,-2.34], P<0.000 01).(3)In terms of regulating blood lipids, GLT+Western medicine was superior to Wes-tern medicine alone(MD_(TC)=-1.40, 95%CI[-2.13,-0.66], P=0.000 2; MD_(TG)=-1.29, 95%CI[-1.86,-0.73], P<0.000 01; MD_(LDL-C)=-1.48, 95%CI[-2.91,-0.04], P=0.04; MD_(HDL-C)=0.07, 95%CI[0.02, 0.12], P=0.009).(4)In terms of incidence of adverse reactions, there was no statistical difference between GLT+Western medicine and Western medicine alone(RR=0.63, 95%CI[0.30, 1.32], P=0.22). The results of the evaluation showed that the evidence level of each outcome indicator was low, and the recommendation was at weak level. In conclusion, GLT+Western medicine could improve the total clinical efficiency, neurological function score, and blood lipid status, with a low incidence of adverse reactions. However, due to the small amount of included stu-dies, low study quality and low level of evidence, it is expected to carry out clinical studies with standardized design and large sample size in the future to further investigate the clinical efficacy and safety of GLT in the treatment of ACI.

ABSTRACT

Due to worldwide abuse of chemical antibiotics and continuous emergence of "superbugs", the harm of bacterial drug resistance to human beings has become more and more serious. Therefore, it is of great significance to look for green antibiotics with a wide range of sources, broad antibacterial spectrum, non-toxicity or low toxicity, environmentally friendliness, diverse active components and low drug resistance. The volatile oil of traditional Chinese medicine is a kind of volatile oily liquid that exists in plants and can be distilled with steam and immiscible with water. Because of its good potential to resist drug-resistant pathogens, it is widely used in food, medicine and other fields. This paper summarized the antibacterial advantages and characteristics of volatile oil of traditional Chinese medicine, and the antibacterial effect and antibacterial mechanism of combined application of volatile oil of traditional Chinese medicine, in order to provide some theoretical basis and study ideas for solving the problem of bacterial drug resistance and developing natural and green antibiotics.

ABSTRACT

As a precious traditional Chinese medicine(TCM), snake bile has been widely used in numerous Chinese medicine prescriptions. Bile acid(BA) derivatives have been demonstrated as the primary chemical family in snake bile. In-depth chemical characterization of BAs is of great importance towards the establishment of quality standards and clarification of the effective material basis for snake bile. This study firstly employed ~1H-NMR to preliminarily analyze the chemical profiles of snake bile, an automated fraction collector was subsequently implemented to obtain the fractions-of-interest. The fraction was then concentrated and re-analyzed by LC-MS. Based on ~1H-NMR, BAs were found to be the main components of snake bile, and six BAs including CDCA, CA, TCDCA, TCA, TDCA and GCA were tentatively identified from the representative spectrum with the assistance of literature and reference compounds. Whereas the content of TCA in snake bile was too great, resulting in a great obstacle for the detection of trace components, the automated fraction collector was subsequently implemented to obtain the fractions-of-interest for LC-MS analysis. According to matching MS/MS information and retention time with reference compounds as well as database retrieval, a total of 57 BAs were detected and annotated. Because of the combination of ~1H-NMR and LC-MS platforms, the findings are beneficial for the in-depth characterization of BAs in snake bile, which provides references for the establishment of quality control and evaluation methods of snake bile.

ABSTRACT

The present study aims to investigate the effects of aerobic exercise and resistance exercise on lipid metabolism of skeletal muscle in high-fat diet (HFD)-induced insulin-resistant (IR) rats and the underlying mechanisms. Male Sprague-Dawley (SD) rats at age of 10 weeks were fed with HFD for 10 weeks to establish IR model. The IR rats were then randomly assigned into 3 groups, including IR control (IR) group, aerobic exercise (AE) group and resistance exercise (RE) group. An additional chow diet sedentary control (CON) group was used as well. Fasting blood glucose (FBG), insulin (FIN), glucagon and lipids, as well as triacylglycerol (TG), free fatty acids (FFA), and the protein expression of fatty acid translocase/cluster of differentiation 36 (FAT/CD36), carnitine palmitoyltransferase-1 (CPT-1), stearoyl-CoA desaturase-1 (SCD-1) and peroxisome proliferators-activated receptors γ (PPARγ) in skeletal muscles were measured after 8-week exercise interventions. The results showed that the contents of FBG, FIN, and LDL-C were increased by IR compared with CON group, and significantly decreased by aerobic exercise and resistance exercise; while aerobic exercise induced an increase in HDL-C as well. Furthermore, IR exhibited no significant effects on TG content of skeletal muscles, but significantly increased FFA level. Both aerobic and resistance exercise led to a decrease in TG content, and FFA level was increased by aerobic exercise but deceased by resistance exercise. In addition, the protein expression of FAT/CD36, SCD-1 and PPARγ was increased and that of CPT-1 was decreased by IR, while both types of exercise resulted in a decrease in the protein expression of FAT/CD36, SCD-1 and PPARγ, and an increase in CPT-1. In conclusion, aerobic and resistance exercise may attenuate IR through decreasing HFD-induced ectopic fat deposition and increasing β-oxidation of fatty acids in skeletal muscle cells, and resistance exercise shows a greater improvement in lipid metabolism of skeletal muscles than aerobic exercise.

ABSTRACT

BACKGROUND@#Methylene blue is the most commonly used tracer for sentinel lymph node (SLN) biopsy (SLNB) in China. This study aimed to investigate the feasibility of clinical application of SLNB using methylene blue dye (MBD) for early breast cancer and the prognosis of patients with different SLN and non-SLN statuses.@*METHODS@#We retrospectively analyzed the clinicopathological data of patients with early breast cancer treated at the Peking University First Hospital between 2013 and 2018. We calculated the SLN identification rate (IR) in SLNB with MBD and the false-negative rate (FNR), and analyzed the prognosis of patients with different SLN and non-SLN statuses using Kaplan-Meier curves.@*RESULTS@#Between January 2013 and December 2018, 1603 patients with early breast cancer underwent SLNB with MBD. The SLN IR was 95.8% (1536/1603). Two SLNs (median) were detected per patient. There were significant differences in FNR between patients with SLN micrometastasis and macrometastasis (19.0% vs. 4.5%, χ2 = 12.771, P < 0.001). Chi-square test showed that there were significant differences in SLN successful detection rates among patients with different vascular tumor embolism status (96.3% vs. 90.8%, χ2 = 9.013, P = 0.003) and tumor (T) stages (96.6% vs. 94.1%, χ2 = 5.189, P = 0.023). Multivariate analysis showed that vascular tumor embolism was the only independent factor for SLN successful detection (odds ratio: 0.440, 95% confidence interval: 0.224-0.862, P = 0.017). Survival analysis showed a significant difference in disease-free survival (DFS) between patients with non-SLN metastasis and patients without non-SLN metastasis (P = 0.006).@*CONCLUSION@#Our single-center data show that, as a commonly used tracer in SLNB in China, MBD has an acceptable SLN IR and a low FNR in frozen sections. This finding is consistent with reports of dual tracer-guided SLNB. Positive SLNs with non-SLN metastasis are associated with DFS.

ABSTRACT

OBJECTIVE@#To verify the clinical effect of acupuncture on knee osteoarthritis (KOA).@*METHODS@#Forty-two patients with KOA were randomly divided into an acupuncture group (21 cases, 1 case dropped off) and a sham acupuncture group (21 cases, 1 case dropped off). The patients in the acupuncture group were treated with routine acupuncture at 5-6 local acupoints [Dubi (ST 35), Neixiyan (EX-LE 4), Heding (EX-LE 2), Yinlingquan (SP 9), Xuehai (SP 10), Zusanli (ST 36), etc.] and 3-4 distal acupoints [Fengshi (GB 31), Waiqiu (GB 36), Xuanzhong (GB 39), Zulinqi (GB 41), etc.]. The patients in the sham acupuncture group were treated with shallow needling technique at non-acupoint. The needles were retained for 30 min in both groups. All the treatment was given three times a week for 8 weeks. Knee injury and osteoarthritis outcome score (KOOS) were recorded before and after treatment and 18-week follow-up.@*RESULTS@#Compared before treatment, the scores of 5 dimensions of KOOS [pain, symptoms (except pain), daily activities, sports and entertainment, and quality of life] were increased after treatment and during follow-up in the two groups (@*CONCLUSION@#Acupuncture can reduce the pain symptoms and improve daily activities in patients with KOA.

ABSTRACT

Research on the material basis of Chinese materia medica (CMM) is the basis for modernization of CMM. High-resolution mass spectrometry (HRMS) has become a powerful tool for the qualitative analysis of the components of CMM. Some data-mining strategies based on high-resolution mass spectrometry, such as full-information tandem mass spectrometry scanning acquisition strategy, sequential windowed acquisition of all theoretical fragment ions, mass detect filter, characteristic ion filter, mass spectral tree similarity filter, etc. have greatly promoted the elucidation of the qualitative basis of CMM. In order to provide methods for the rapid discovery and structural characterization of components and metabolites of CMM, this review summarized the advances in HRMS-based data-mining technologies for detecting and characterizing the compounds and metabolites of CMM, which includes class compounds, all compounds and metabolites.

ABSTRACT

Objective:To compare the clinical outcomes between OTA/AO-C open and closed fractures of the distal humerus treated by open reduction and internal fixation.Methods:The clinical data were retrospectively analyzed of the 70 patients who had been treated at Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital for OTA/AO-C fractures of the distal humerus from January 2014 to June 2017. Of them, 22 suffered from open fractures (Gustilo types Ⅰ/Ⅱ) and 48 closed fractures. There were 18 males and 4 females with an age of (42.6±13.0) years in the open group and 21 males and 27 females with an age of (42.2±17.1) years in the closed group. Analyzed were interval from injury to surgery, hospitalization time, injury energy and functional outcomes which included range of motion (ROM) in elbow flexion and extension, ROM in elbow rotation, Mayo elbow performance score (MEPS), Disabilities of the Arm, Shoulder and Hand (DASH), complications and rate of secondary surgery.Results:There was no significant difference between the 2 groups in age, injury energy or interval from injury to surgery ( P>0.05), but there were significantly more males in the open group than in the closed group ( P=0.011). The follow-up time for all the patients averaged 34.0 months (from 25 to 54 months). There were no statistically significant differences between the 2 groups in hospitalization time [9.5(6.0, 13.0) d versus 8.5 (6.0, 11.0) d], ROM in flexion and extension [120.0° (100.0°, 137.8°) versus 128.5° (110.0°, 140.0°)], ROM in rotation [155.0° (151.3°, 155.0°) versus 155.0° (155.0°, 155.0°)], MEPS [95.0 (80.0, 100.0) versus 95.0 (80.0, 100.0)] or DASH [2.6 (0.63, 9.2) versus 1.7 (0.0, 8.5)] ( P>0.05). There were no statistically significant differences between the 2 groups either in rate of secondary surgery [36.4% (8/22) versus 33.3% (16/48)], ulnar nerve symptoms [54.5% (12/22) versus 60.4% (29/48)], local irritability in the region of internal fixation [9.1% (2/22) versus 6.3% (3/48)] or elbow stiffness [13.6% (3/22) versus 10.4% (5/48)] ( P>0.05). Conclusion:Open reduction and internal fixation can lead to similar clinical outcomes in the treatment of both open (Gustilo types Ⅰ/Ⅱ) and closed distal humeral fractures of OTA/AO-C, with no significant differences in postoperative ROM, functional scores or complications.

ABSTRACT

Congenital heart disease is one of the most common birth defects, which is the main cause of death in children.Cardiovascular development is a complex process involving multiple genes, signaling pathways and regulatory factors.According to the sequencing of human genome and encode project, more than 80% of the genes in the genome are transcribed, but only 3% of these transcripts correspond to protein-encoding RNA.It is pointed out that non-coding RNA is as important or even more important as encoding RNA.More and more evidences show that not only encoding genes are involved in the regulation of cardiovascular development, but also protein non-coding genes play an important role in the development of heart.This review will summarize the biological characteristic and function of long noncoding RNAs, and introduce the role of some representative lncRNA in heart development and congenital heart disease.

ABSTRACT

Huang-Qin Decoction (HQD) is a classic prescription for diarrhea in Chinese medicine treatment. Recent studies have demonstrated that HQD and its modified formulation PHY906 could ameliorate irinotecan (CPT-11) induced gastrointestinal (GI) toxicity and enhance its anticancer therapeutic efficacy. Nevertheless, which constituents in HQD are effective is still unclear so far. The study aims to screen out the key bioactive components combination from HQD that could enhance the anticancer effect of CPT-11. First, the potential bioactive constituents were obtained through system pharmacology strategy. Then the bioactivity of each constituent was investigated synthetically from the aspects of NCM460 cell migration, TNF-α release of THP-1-derived macrophage and MTT assay in HCT116 cell. The contribution of each constituent in HQD was evaluated using the bioactive index E

ABSTRACT

From the perspective view of Chinese medicine, the Gan (Liver) meridian of Foot-Jueyin starts from the great toe, running upward along the medial side of the thigh to the perineal area, where it curves around the external genitalia and goes up to the lower abdomen. In clinical practice, acupoints in the feet of the Gan meridian of Foot-Jueyin are used to treat the genitourinary and external genitalia diseases. Studies have shown that reproductive system diseases have specific pathological reactions in the places (radial side of tibia and foot) where Gan meridian of Foot-Jueyin passes by. Why does this happen? In this article, we begin by briefly reviewing the evidences linking foot and genitalia. We then explore the potential mechanism of the relationship between genitals and the Gan meridian of Foot-Jueyin. The brain cerebral cortex is characterized by cortical interactions. Numerous studies show that different cerebral cortex function areas (especially the adjacent areas) are overlapping and interact with each other. Finally, we presume that there is a specific connection between the feet and the genitals. Physiologically in the cortical homunculus, the genital area lies adjacent or overlapped to the foot areas, the two areas may interact with each other. The functional reorganization between different areas of the cerebral cortex under pathological conditions may be the underlying mechanism of the relationship between the feet and the genitals.

ABSTRACT

OBJECTIVE@#To study the clinical features of very preterm small-for-gestational-age infants born by cesarean section due to severe preeclampsia.@*METHODS@#Forty-two small-for-gestational-age infants who were admitted from August 2017 to July 2018 and were born due to severe preeclampsia were enrolled as the observation group. Forty very preterm infants who were born to healthy mothers since uterine contractions could not be suppressed were enrolled as the control group. Perinatal features, clinical manifestations of infection, complications, and clinical outcomes were analyzed for the two groups.@*RESULTS@#Within 6 hours and 2-3 days after birth, the observation group had significantly lower white blood cell count (WBC), absolute neutrophil count (ANC), and platelet count (PLT) than the control group (@*CONCLUSIONS@#Very preterm small-for-gestational-age infants born due to severe preeclampsia have a high incidence rate of infection and severe conditions. Early manifestations include reductions in the infection indicators WBC, ANC, and PLT, and CRP does not increase significantly in the early stage and gradually increases at 2-3 days after birth. Most of these infants require invasive ventilation after birth, with bronchopulmonary dysplasia as the main complication. Clinical changes should be closely observed and inflammatory indicators should be monitored for early identification of infection, timely diagnosis, and timely adjustment of antibiotic treatment, so as to improve the outcome.

ABSTRACT

Objective To analyze the intake and changes of food and nutrients in 223 residents of Yangpu District from 2011 to 2015. Methods From the China Nutritional Transition Cohort Study in 2011 and 2015, the data in the study was obtained on Yangpu District′s residents aged 2 and above.A dietary survey was conducted using the 3-day 24-hour dietary recall and condiment weighing method to obtain data on food and nutrients intake per reference man per day and the nutrient source of energy, and to analyze the intake status of different years. Results The intake of vegetables, fruits, livestock and poultry, aquatic products, eggs, milk and dairy products, soybeans and nuts, edible oil and salt per reference man per day was lower in 2015 than in 2011.The insufficient intake proportions of cereals and tubers, vegetables, fruits, aquatic products, eggs, milk and dairy products, soybeans and nuts, and edible oils were 56.0%, 84.0%, 98.2%, 56.0%, 70.2%, 97.8%, 85.3% and 91.1%, respectively, the excessive intake proportion of livestock and poultry meat was 51.6%;the intake of energy, protein, fat and micronutrient per reference man per day in 2015 was lower than in 2011, and the insufficient intake proportion of energy, protein, vitamin A, vitamin B1, vitamin B2, vitamin C, and calcium were 84.0%, 56.4%, 97.3%, 93.8%, 93.3%, 90.2% and 91.6%, respectively.In 2011 and 2015, it was found that residents who had the proportions of energy supply from carbohydrate lower than 50% accounted for 64.6% and 49.8%, those who had the proportions of energy supply from protein higher than 15% accounted for 76.2% and 40.4%, and those who had the proportions of energy supply from fat higher than 30% accounted for 76.7% and 72.9%. Conclusion In 2011-2015, the food and nutrients intakes among community residents in Yangpu District generally decrease, showing the coexistent problems of insufficient and excessive food intake, and the insufficient intake is serious.The insufficient intake of energy, vitamins and calcium is still a severe problem.And the dietary structure is not rational; the proportions of energy supply from three major nutrients are unbalanced.It is suggested that nutrition education for residents should be enhanced.

ABSTRACT

OBJECTIVE@#To study the pharmacokinetic characteristics, clinical effect, and safety of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in children with acute lymphoblastic leukemia (ALL).@*METHODS@#A prospective study was performed on children with ALL who cyclophosphamide, cytarabine, and 6-mercaptopurine were used for consolidation therapy. PEG-rhG-CSF (PEG-rhG-CSF group) or rhG-CSF (rhG-CSF group) was injected after chemotherapy. The plasma concentration of PEG-rhG-CSF was measured, and clinical outcome and safety were observed for both groups.@*RESULTS@#A total of 17 children with ALL were enrolled, with 9 children in the PEG-rhG-CSF group and 8 children in the rhG-CSF group. In the PEG-rhG-CSF group, the peak concentration of PEG-rhG-CSF was 348.2 ng/mL (range 114.7-552.0 ng/mL), the time to peak was 48 hours (range 12-72 hours), and the half life was 14.1 hours (range 11.1-18.1 hours). The plasma concentration curve of PEG-rhG-CSF was consistent with the mechanism of neutrophil-mediated clearance. Compared with the rhG-CSF group, the PEG-rhG-CSF group had a significantly shorter median time to absolute neutrophil count (ANC) recovery (P0.05).@*CONCLUSIONS@#The pharmacokinetic characteristics of PEG-rhG-CSF in children with ALL receiving consolidation chemotherapy are consistent with the mechanism of neutrophil-mediated clearance, with a short half life and fast recovery of ANC, and there are no significant differences in safety between PEG-rhG-CSF and rhG-CSF.

ABSTRACT

Objective To investigate the prevalence and risk factors of Blastocystis infections among primary school students in Jiangjin District, Chongqing City. Methods A cross-sectional questionnaire survey was conducted among students sampled from a primary school in Jiangjin District, Chongqing City on April, 2018, and their stool samples were collected for microscopic examinations, in vitro culture and PCR assays to analyze the prevalence of Blastocystis infections and subtype of the parasite. In addition, the risk factors of Blastocystis infections among primary school students were identified using univariate analysis and multivariate logistic regression analysis. Results A total of 466 primary students were surveyed, and the subjects had a mean age of (9.81±1.66) years and included 236 males (50.64%) and 230 females (49.36%). The prevalence of Blastocystis infections was 15.24% (71/466) among the study students, and there was no significance difference in the prevalence between male and fe- male students (16.52% vs. 13.91%; χ2 = 0.616, P = 0.433). In addition, there was a significant difference in the prevalence of Blastocystis infections among grade 1 (6.35%, 4/63), grade 2 (5.17%, 3/58), grade 3 (21.74%, 15/69), grade 4 (25.30%, 21/83), grade 5 (10.19%, 11/108) and grade 6 students (20.00%, 17/85) (χ2 = 15.410, P = 0.009). There were four Blastocystis subtypes characterized (ST1, ST3, ST6 and ST7), in which ST6 was the most common subtype (45.07%, 32/71), followed by ST3 (25.35%, 18/71). Multivariate logistic regression analysis revealed that minority ethnicity [odds ratio (OR) = 4.259, 95% confidential inter- val (CI) : (1.161, 15.621)] and low maternal education level (primary school and below) [OR = 9.038, 95% CI: (1.125, 72.642)] were identified as risk factors of Blastocystis infection among primary school students in Jiangjin District, Chongqing City. Conclusions There is a high prevalence of Blastocystis infections detected among primary school students in Jiangjin District, Chongqing City, and ST6 and ST3 are predominant subtypes. Minority ethnicity and low maternal education level (primary school and below) are risk factors for Blastocystis infections in primary school students.
