Acupotomy versus nonsteroidal anti-inflammatory drugs for knee osteoarthritis: Protocol for a systematic review and meta-analysis.

BACKGROUND: Knee osteoarthritis (KOA), a common clinical chronic osteoarthropathy, has adverse effects on the working ability and life quality of patients. At present, acupotomy and nonsteroidal anti-inflammatory drugs (NSAIDs) have been widely applied on KOA in China and has achieved satisfactory results. However, there is no systematic review comparing the effectiveness of these two therapies for KOA. Therefore, this study will assess the efficacy and safety of acupotomy in treating KOA. METHODS AND ANALYSIS: Several databases including CNKI, Wanfang Database, CBM, VIP, PubMed, Cochrane library, Web of Science, and Embase will be used by two independent researchers to search the related clinical RCTs about acupotomy therapy for KOA patients until May 2019. Subsequently, meta-analysis will be conducted by using Review Manager 5.3, and the related data will be analyzed by using the method for GRADE. The continuous data will be presented as the WMD or SMD with 95% CI, while dichotomous data will be shown as the RR with 95% CI. CONCLUSION: Our results review will provide evidence to determine whether acupotomy can achieve the effect of NSAIDs, or whether it has advantages and safety compared with NSAIDs for patients with KOA. ETHICS AND DISSEMINATION: This study will not involve personal information. The ethical approval will not be required. This systematic review will be disseminated electronically through a peer-reviewed journal or international conference presentations. PROSPERO REGISTRATION NUMBER: CRD42019129089.

Twice daily short-message-based re-education could improve Helicobacter pylori eradication rate in young population: A prospective randomized controlled study.

BACKGROUND: To investigate the effects of twice daily short-message-based re-education (SMRE) before taking medicine for Helicobacter pylori (H pylori) eradication. MATERIALS AND METHODS: Treatment-naive patients with H pylori infection were prescribed 14-day quadruple regimen consisting of lansoprazole 30 mg, colloidal bismuth pectin 200 mg, amoxicillin 1000 mg, and clarithromycin 500 mg twice daily. Patients were randomly allocated to SMRE group or control group. Patients in control group received oral and written instructions at outpatient clinic. In contrast, patients in the SMRE group received extra short messages including dosage and time of administration twice daily. Successful H pylori eradication was assessed using the 13 C-urea breath test 6 weeks after treatment. The compliance, adverse events, and patient satisfaction were also analyzed. RESULTS: A total of 310 patients were enrolled in the intention-to-treat (ITT) and 283 in the per-protocol (PP) analysis. For young patients, the eradication rates were significantly higher in SMRE group than those in control group in PP analysis (88.6% vs 71.2%, P = 0.036), while for patients of all age groups, the eradication rate improvements were not statistically significant. The eradication rates in SMRE group and control group were 74.2% and 67.7% (P = 0.211) in ITT analysis and 82.1% and 73.4% (P = 0.078) in PP analysis, respectively. The compliance in SMRE group was significantly better than that in control group (84.8% vs 72.8%, P = 0.011). CONCLUSIONS: Twice daily SMRE could improve the eradication rate in young population, as well as the compliance with treatment during H pylori eradication.

[Relationship between dietary pattern during late pregnancy and fatty acid composition of transitional milk in inland regions of China].

OBJECTIVE: To investigate dietary pattern during late pregnancy and fatty acid composition of transitional milk in inland regions of China. METHODS: Eighty Chinese women were recruited from two different geographical inland regions (Jurong, an inland region close to freshwater. Xushui, an inland region with limited access to freshwater, forty women from each region) during late pregnancy. Their dietary status during late pregnancy was recorded and fatty acid composition in transitional milk was quantified. RESULTS: Both marine fish consumption frequencies during late pregnancy were less than one time/week. The consumption of rapeseed oil in Jurong was significantly higher than in Xushui (P < 0.05). The total lipids contents of Jurong and Xushui were (4.39 ± 1.18) g/100g and (3.92 ± 1.47) g/100g, respectively (P = 0.11), and DHA composition were (0.46 ± 0.20 )% and (0.29 ± 0.09 )%, respectively (P < 0.05). There was positive relationship between rapeseed oil consumption and DHA in transitional milk (r = 0.362, P < 0.05). CONCLUSION: Fatty acid composition in transitional milk differed between these two inland regions of China, which may be caused by difference of maternal dietary pattern during late pregnancy. The intake of precursor of n-3 long chain polyunsaturated fatty acid could compensate its dietary deficiency to some extent.

Fuzhuanins A and B: the B-ring fission lactones of flavan-3-ols from Fuzhuan brick-tea.

Fuzhuan brick-tea is a special dark tea prepared from the leaves of Camellia sinensis var. sinensis. Its production involves a fungal fermentation stage, which forms the unique flavors and functions by a series of biochemical reactions. Our phytochemical research of the material led to the isolation of two new B-ring fission lactones of flavan-3-ols, fuzhuanins A (1) and B (2). In addition, three other flavan-3-ol derivatives (3-5), three flavone C-glycosides (6-8), eight flavonoid O-glycosides (10-17), five simple phenolics (19-23), two norisoprenoid glycosides (24, 25), two sesquiterpenoids (26, 27), and theobromine (28), as well as two flavonoid anions (9 and 18), were also identified. The structures of these compounds were determined by spectroscopic methods. Compounds 4, 19, 20, 22-24, 26, and 27 were reported for the first time in Camellia spp. and tea. Furthermore, HPLC analysis method was performed to compare the chemical constituents of the before/after fungal fermentation Fuzhuan brick-teas. Compound 1 was indicated as one of the major characteristic constituents generated in the fungal fermentation process. The IC50 value of the antiproliferative activity of 2 on HeLa cells was assayed as 4.48 µM. None of the isolated compounds showed any inhibition activity against the enteric pathogenic microbes at 800 µg/mL by the hole plate diffusion method.

The fatty acid composition of colostrum in three geographic regions of China.

PURPOSE: To describe the fatty acid composition of human colostrum in three different regions of China. METHODS: Women were recruited from river/lake, coastal and inland regions of China during late pregnancy. Their diet frequency was assessed during the 34th week of pregnancy. Colostrum samples were collected between postpartum days 3 and 5. Thirty-one different fatty acids were separated and identified in colostrum. RESULTS: There were significant differences among the women in the three regions with respect to food and culinary oil consumption patterns. The mean±SD fat content (g/100 g) of colostrum from river/lake, coastal and inland regions was 2.17±1.26, 2.50±1.39 and 2.68±1.26, respectively (p=0.265, adjusted by pregnant women's age). The main saturated, monounsaturated, n-6 polyunsaturated and n-3 polyunsaturated fatty acids in colostrum were 16:0, 18:1n9, 18:2n6 and 18:3n3, respectively. Colostrum from river/lake region had the lowest composition of total SFA and of total n-6 PUFA and the highest composition of total MUFA and of total n-3 PUFA. The amount of DHA (22:6n3) in colostrum (mean±SD, % wt/wt) was 0.51±0.18, 0.52±0.20 and 0.35±0.13 in the river/lake, coastal and inland regions, respectively (p=0.0002, adjusted by pregnant women's age). Frequency of maternal marine fish intake during the late pregnancy was positively correlated with DHA in colostrum (r=0.203, p=0.040). CONCLUSIONS: The fatty acid composition of colostrum differs across geographical regions in China, which may be related to differences in maternal dietary pattern.

Randomized controlled trial of oatmeal consumption versus noodle consumption on blood lipids of urban Chinese adults with hypercholesterolemia.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death in China and worldwide. Whole grain oats can reduce risk of CVD by reducing total and LDL-cholesterol, major risk factors for CVD. While this association has been established in many populations, data from Asian populations is limited. Thus, this study investigated the impact of oat consumption on cholesterol levels in Chinese adults. Male and female data from this work were previously published separately in mandarin in two Chinese journals. The combined male and female data were reanalyzed and are presented here. METHODS: A randomized, controlled, parallel-arm study was conducted at Beijing Hospital, Beijing china. Subjects were adults (men and women) with mild to moderate hypercholesterolemia. The oat group (n=85) consumed 100 grams of instant oat cereal versus the control group (n=81) who consumed 100 grams of wheat flour-based noodles daily for 6 weeks. Laboratory and anthropometric measurements were conducted at baseline and at the end of the 6-week intervention. RESULTS: Dietary fiber intake increased significantly in the oat group compared to the control group at the end of the 6-week intervention. Total-, LDL-cholesterol and waist circumference decreased significantly in the oat group compared to the control. HDL-cholesterol decreased significantly in the control group versus the oat group. There were no significant changes in blood pressure, other anthropometric or laboratory measures between the two groups at the end of the intervention. CONCLUSIONS: Instant oatmeal consumed daily for 6 weeks significantly increased fiber intake and decreased major risk factors for CVD in Chinese adults with hypercholesterolemia. Increased consumption of whole grains, including oats, should continue to be encouraged.

Efficient 2,3-butanediol production from cassava powder by a crop-biomass-utilizer, Enterobacter cloacae subsp. dissolvens SDM.

BACKGROUND: 2,3-Butanediol (BD) is considered as one of the key platform chemicals used in a variety of industrial applications. It is crucial to find an efficient sugar-utilizing strain and feasible carbon source for the economical production of BD. METHODOLOGY/PRINCIPAL FINDINGS: Efficient BD production by a newly isolated Enterobacter cloacae subsp. dissolvens SDM was studied using crop-biomass cassava powder as substrate. The culture conditions and fermentation medium for BD production were optimized. Under the optimal conditions, 78.3 g l(-1) of BD was produced after 24 h in simultaneous saccharification and fermentation (SSF), with a yield of 0.42 g BD g(-1) cassava powder and a specific productivity of 3.3 g l(-1) h(-1). A higher BD concentration (93.9 g l(-1)) was produced after 47 h in fed-batch SSF. CONCLUSIONS/SIGNIFICANCE: The results suggest that strain SDM is a good candidate for the BD production, and cassava powder could be used as an alternative substrate for the efficient production of BD.

A new norisoprenoid and other compounds from Fuzhuan brick tea.

Fuzhuan brick tea, a kind of dark tea consumed mainly in the border regions of Southwestern and Northwestern China since the 1860s, is produced from the leaves of Camellia sinensis var. sinensis by microbial fermentation. From this special fermented tea, a new norisoprenoid, 3R,9R-oxido-5-megastigmene, was isolated, together with α-linolenic acid, strictin, isovitexin, astragalin, (+)-catechin, (-)-epicatechin, (-)-epicatechin gallate, (+)-gallocatechin, (-)-epigallocatechin, (-)-epigallocatechin gallate and gallic acid. The structures of the compounds were identified by spectroscopic means. The new compound didn't show any inhibition activity against the tested enteric pathogenic microorganisms at a concentration of 800 µg/mL by the hole plate diffusion method.

Dietary inclusion of salmon, herring and pompano as oily fish reduces CVD risk markers in dyslipidaemic middle-aged and elderly Chinese women.

Dietary intervention studies to assess the cardioprotective effects of oily fish are scarce in China. The present study aimed to examine the effects of the oily fish, Norwegian salmon, herring and local farmed pompano (Trachinotus ovatus) on CVD risk markers when included in the Chinese diet. In this 8-week, parallel-arm, randomised intervention study, 126 Chinese women with hypertriacylglycerolaemia, aged 35-70 years, were assigned to four groups to consume an experimental lunch containing 80 g fillets of either one of three oily fish or a mix of commonly eaten meats (pork/chicken/beef/lean fish) for 5 d/week. The results showed that inclusion of the three oily fish significantly increased the intake of n-3 long-chain PUFA (LC-PUFA) while decreasing the dietary n-6:n-3 PUFA ratio. Compared to the control group, significant increases of DHA, EPA+DHA and total n-3 PUFA in plasma choline phosphoglyceride were observed in the three oily fish groups. Plasma TAG levels were significantly reduced only in the salmon and herring groups. When compared to the baseline level, the three oily fish diets significantly decreased serum concentrations of TAG, apoB, apoCII and apoCIII, but only the salmon and herring diets significantly lowered TNF-α and raised adiponectin levels in serum. The salmon diet additionally decreased the serum concentration of IL-6. To conclude, dietary inclusion of salmon, herring and pompano as oily fish can effectively increase serum n-3 LC-PUFA content and are associated with favourable biochemical changes in dyslipidaemic middle-aged and elderly Chinese women, and these beneficial effects are mainly associated with n-3 LC-PUFA contents.

Inclusion of Atlantic salmon in the Chinese diet reduces cardiovascular disease risk markers in dyslipidemic adult men.

Although the beneficial effects of n-3 fatty acids on several physiologic functions have been widely reported, information about the effects of oily fish in the Asian diet on cardiovascular disease (CVD) risk is diminutive. We hypothesize that daily inclusion of oily fish for 8 weeks in the Chinese diet will elevate serum eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels and reduce CVD risk markers in dyslipidemic adult men, comparable with the effects generally observed by inclusion of oily fish in the Western diet. In this 8-week randomized, parallel-arm, food-based intervention study, lunches were prepared with 500 g pork/chicken/beef, typically consumed fish (hairtail and freshwater carp), or oily fish (salmon). Male subjects aged between 35 and 70 years with hyperlipidemia were randomly assigned to eat lunches with pork/chicken/beef (n = 30 subjects at 8 weeks), freshwater fish (n = 30), or oily fish (n = 32). Circulating markers were measured at baseline and at 8 weeks. In the oily fish diet, dietary EPA and DHA levels were significantly increased as compared with other diets; and the n-6:n-3 polyunsaturated fatty acid ratio was decreased (P < .05). Thus, the oily fish diet significantly elevated serum EPA and DHA concentrations (P < .01) and lowered serum n-6:n-3 ratio at 8 weeks (P < .05). Furthermore, oily fish intake significantly reduced serum levels of triglycerides (P < .05) and interleukin-6 (P < .01) and increased levels of high-density lipoprotein cholesterol (P < .01). In conclusion, daily inclusion of oily fish as part of the Chinese diet for 8 weeks is sufficient to significantly increase the serum content of long-chain n-3 polyunsaturated fatty acids and reduce levels of CVD risk markers in dyslipidemic adult men.
