RESUMO
BACKGROUND AND OBJECTIVES: Citrus fruit are suggested to be associated with reduced risk of nasopharyngeal carcinoma (NPC), but findings from epidemiologic studies have been inconsistent. We aimed to synthesize the association by conducting a meta-analysis of existing evidence. METHODS AND STUDY DESIGN: Databases including Medline, EMBASE, Web of science, and the Cochrane Library were searched for eligible studies up to March 2019 using a series comprehensive searching terms. The adjusted odds ratios (ORs) of citrus fruit intake with NPC risk from each study were extracted to calculate a pooled association estimate with its 95% confidence interval (CI). RESULTS: Nine studies totaling 3304 cases and 3850 controls were included in this analysis. Citrus fruit intake was significantly associated with reduced risk of NPC (OR: 0.72, 95% CI 0.58-0.91, p=0.005). In addition, this association tended to be stronger in Chinese (OR: 0.67, 95% CI 0.54-0.84, p<0.001). Dose-response analysis using cubic splines showed the risk of NPC decreased by 21% for citrus fruit intake of 4 times/week (OR: 0.79, 95% CI 0.66-0.94). CONCLUSIONS: Consumption of citrus fruit was associated with a significantly reduced risk of NPC, especially in Chinese.

Previous studies have examined rotenone toxicity on the human central nervous system, especially in the pathogenesis of Parkinson's disease, but few have investigated the effects of rotenone on the kidney. Here, rotenone-induced nephrotoxicity was evaluated by determining morphological, biochemical, oxidative stress-related, and apoptotic factor alterations in rat renal tissue. Morphological and biochemical analyzes showed that rotenone administration to rats damaged renal tissue. Western blot results revealed that rotenone-induced oxidative damage, causing overproduction of glutathione, malonaldehyde, and reactive oxygen species (ROS), and inhibiting superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activity. Rotenone also decreased the mitochondrial membrane potential and increased voltage-dependent anion channel (VDAC), caspase-3, and caspase-9 protein levels, indicating an association of apoptosis with renal damage. Our results suggest that glutathione, malonaldehyde, and ROS may be signals of rotenone-induced oxidative damage, and that the mitochondrial pathway plays a key role in apoptosis of renal cells following rotenone administration.

5-Aminolevulinic acid (5-ALA) has been suggested for improving plant salt tolerance via exogenous application. In this study, we used a transgenic canola (Brassica napus), which contained a constituted gene YHem1 and biosynthesized more 5-ALA, to study salt stress responses. In a long-term pot experiment, the transgenic plants produced higher yield under 200 mmol L(-1) NaCl treatment than the wild type (WT). In a short-term experiment, the YHem1 transformation accelerated endogenous 5-ALA metabolism, leading to more chlorophyll accumulation, higher diurnal photosynthetic rates and upregulated expression of the gene encoding Rubisco small subunit. Furthermore, the activities of antioxidant enzymes, including superoxide dismutase, guaiacol peroxidase, catalase and ascorbate peroxidase, were significantly higher in the transgenic plants than the WT, while the levels of O2 ·(-) and malondialdehyde were lower than the latter. Additionally, the Na(+) content was higher in the transgenic leaves than that in the WT under salinity, but K(+) and Cl(-) were significantly lower. The levels of N, P, Cu, and S in the transgenic plants were also significantly lower than those in the WT, but the Fe content was significantly improved. As the leaf Fe content was decreased by salinity, it was suggested that the stronger salt tolerance of the transgenic plants was related to the higher Fe acquisition. Lastly, YHem1 transformation improved the leaf proline content, but salinity decreased rather than increased it. The content of free amino acids and soluble sugars was similarly decreased as salinity increased, but it was higher in the transgenic plants than that in the WT.

Introduction: Transcutaneous electrical acupoint stimulation (TEAS) has been proposed for postoperative urinary retention (POUR). This meta-analysis evaluated the effect of TEAS in preventing POUR. Methods: Databases were searched until February 6, 2023. Randomized controlled trials (RCTs) about TEAS for preventing POUR were included. The primary concern was the incidence of POUR, with post-void residual urine volume as a secondary outcome. Results: Fourteen studies with 2865 participants were identified. TEAS reduced the incidence of POUR (RR = 0.44, 95%CI = 0.33 to 0.58, P < 0.00001) and decreased the post-void residual urine volume (MD = -75.41 mL, 95%CI = -118.76 to -32.06, P = 0.0007). The preventive effect on POUR was found in patients receiving anorectal, gynecologic, orthopedic and biliary surgery, but not urinary surgery. Dilatational- and continuous-wave TEAS had a great outcome in preventing POUR. Intraoperative TEAS, preoperative and intraoperative TEAS, and postoperative TEAS were beneficial, and TEAS was more beneficial when compared with sham TEAS and blank control. It is nevertheless difficult to rule out publication bias. Conclusions: TEAS could prevent POUR. Due to insufficient evidence, multicenter, large-sample and high-quality RCTs should be conducted.

RESUMO
BACKGROUND: The incidence rate for migraine is 12% worldwide, and recurrence is common, which seriously affects the physical and mental health of patients. OBJECTIVE: To observe the clinical effect of Shallow Puncture and More Twirling method of acupuncture in treating migraine and its impact on serum 5-HT and ß-EP. METHODS: A total of 76 patients with migraine were randomized into a control group and acupuncture group with 38 cases in each. In the control group, patients were orally administered flunarizine hydrochloride before sleep, 2 capsules once daily for 4 weeks. In the acupuncture group, Shallow Puncture and More Twirling method was adopted for the acupoints of Sizhukong (SJ 23), Toulinqi (GB 15) Shuaigu (GB 8), Xuanlu (GB 5), Fengchi (GB 20), Waiguan (SJ 5), Zulinqi (GB 41). Patients were given acupuncture 3 times per week for 4 weeks. Then, the total VAS (Visual Analogue Scale) scores, composite score of migraine, serum level of 5-HT and ß-EP, and the clinical efficacy differences were observed before and after treatment and the side-effects were recorded among the two groups. RESULTS: The total VAS scores and composite score of migraine were significantly reduced among both groups after the treatment (P< 0.05), and the serum level of 5-HT and ß-EP was significantly improved (P< 0.05). Compared with control group, the acupuncture group reported lower results in VAS score and migraine composite score (P< 0.05), and higher results in serum 5-HT and ß-EP level (P< 0.05). The acupuncture group with shallow puncture and more twirling method showed a total effective rate of 86.5%, which is higher than the control group (78.4%). The difference is statistically significant (P< 0.05). CONCLUSION: Shallow Puncture and More Twirling method was superior to flunarizine hydrochloride in the treatment of clinical symptoms of migraine. Acupuncture also increases the serum level of 5-HT and ß-EP in migraine.

The previously reported begonias in a limestone forest of Guangxi mainly belong to Begoniasect.Coelocentrum Irmscher. In this article, we described and illustrated a new species in sect. Platycentrum (Klotzsch) A.DC., Begoniaparvibracteata X.X.Feng, R.K.Li & Z.X.Liu, which was discovered in a karst forest of south-western Guangxi. The begonia shows high morphological similarity to B.subhowii S.H. Huang and B.psilophylla Irmscher, but differs from the latter two in its narrower oblique-ovate asymmetric leaf blade, 4 (occasionally 6) tepals of pistillate flower and smaller membranous inflorescence bracts. Molecular phylogenetic analysis, based on ITS sequence data, supports the new species as monophyletic and distinct from B.subhowii and B.psilophylla. Considering its narrow distribution and the disturbance of human activities, the conservation status of new taxon is evaluated as "Vulnerable" (VU B1, B2 ab (i, iv, v), D2) according to the IUCN Red List Categories and Criteria.
RESUMO
BACKGROUND: Chronological age (CA) is not a perfect proxy for the true biological aging status of the body. A new biological aging measure, phenotypic age (PhenoAge), has been shown to capture morbidity and mortality risk in the general US population and diverse subpopulations. This study was aimed at evaluating the association between PhenoAge and long-term outcome of patients with multivessel coronary artery disease (CAD). METHODS: A total of 609 multivessel CAD patients who received PCI attempt and with follow-up were enrolled. The clinical outcome was all-cause mortality on follow-up. PhenoAge was calculated using an equation constructed from CA and 9 clinical biomarkers. Cox proportional hazards regression models and receiver operating characteristic (ROC) curves were performed to evaluate the association between PhenoAge and mortality. RESULTS: Overall, patients with more diseases had older PhenoAge and phenotypic age acceleration (PhenoAgeAccel). After a median follow-up of 33.5 months, those with positive PhenoAgeAccel had a significantly higher incidence of all-cause mortality (P = 0.001). After adjusting for CA, Cox proportional hazards models showed that both PhenoAge and PhenoAgeAccel were significantly associated with all-cause mortality. Even after further adjusting for confounding factors, each 10-year increase in PhenoAge was also associated with a 51% increased mortality risk. ROC curves revealed that PhenoAge, with an area under the curve of 0.705, significantly outperformed CA, the individual clinical chemistry measure, and other risk factors. When reexamining the ROC curves using various combinations of variables, we found that PhenoAge provides additional predictive power to all models. CONCLUSIONS: In conclusion, PhenoAge was strongly associated with all-cause mortality even after adjusting for CA. Our findings suggest that PhenoAge measure may be complementary in predicting mortality risk for patients with multivessel CAD.

Begoniapseudoedulis, a new species in Begoniasect.Platycentrum (Klotzsch) A.DC. (Begoniaceae) from southern Guangxi of China, is here described and illustrated. It morphologically resembles B.edulis H.Lév. and B.dielsiana E.Pritz. ex Diels but differs easily by its hairy petioles and inflorescences, and red hispidulous flower tepals, ovary and capsules. The molecular phylogenetic analysis based on ITS supported that the new species was a monophyletic lineage, separating from both B.dielsiana and B.edulis. Due to its isolated distribution with several small populations, which are possibly disturbed by human activities, the species is considered as "Near Threatened" (NT) according to the IUCN Red List Categories and Criteria.
RESUMO
OBJECTIVE: To compare the therapeutic effect on bronchial asthma between presence of skin reaction and the absence of skin reaction after acupoint application. METHODS: Sixty-one patients with bronchial asthma were treated with acupoint application during the hottest periods of summer ("dog days"). The acupoints included Dingchuan (EX-B 1), Feishu (BL 13), Xinshu (BL 15), Pishu (BL 20) and Shenshu (BL 23). The treatment was given once every 7 days, with the herbal plaster remained for 6 h each time, and 4 treatments were required totally. According to the local skin reaction after acupoint application, a skin reaction group (30 cases, 2 cases dropped off) and a non-skin reaction group (31 cases) were divided. Separately, before treatment and 1 year after treatment, using chronic disease management platform of asthma, the number of asthma attacks, the score of asthma control test (ACT) and the score of asthma quality of life questionnaire (AQLQ) were recorded online. Besides, the therapeutic effect was observed in the two groups 1 year after treatment. RESULTS: One year after treatment, the number of asthma attacks was reduced as compared with that before treatment in the patients of either group (P<0.001), the score of ACT and each domain in AQLQ, i.e. activity limitation, asthma symptoms, psychological state, reactions to stimuli and self-health care as well as the total scores of AQLQ were all increased as compared with those before treatment (P<0.001). The number of asthma attacks in the skin reaction group was less than the non-skin reaction group (P<0.05), the score of ACT and each domain of AQLQ and the total scores of AQLQ were all higher than the non-skin reaction group successively (P<0.05, P<0.01). The total effective rate was 82.1% (23/28) in the skin reaction group, better than 67.7% (21/31) in the non-skin reaction group (P<0.05). CONCLUSION: In treatment of acupoint application for bronchial asthma, the clinical therapeutic effect is better in the patients with local skin reaction after acupoint application. The chronic disease management platform of asthma is convenient for online evaluation.

OBJECTIVE: To explore the rule of clinical application of auricular acupuncture therapy by data mining in order to guide clinical practice. METHODS: The data base about single auricular acupuncture therapy for different clinical diseases was established by collection, sorting, screening, recording, collation, data extraction, statistic analysis on data samples from journals, academic theses dissertations published in near 60 years. The application rules of auricular therapy including its predominant diseases, stimulus modality, therapeutic effect, and angle of needling were summarized by data mining technique. RESULTS: Auricular acupuncture therapy has been widely and mostly used in the internal medicine department, accounting for 48.56%. Of stimulus modalities, auricular point paste and pressure is applied with the highest frequency, accounting for 64%. The highest effective rate is found in the surgery department diseases(81.41%). Pressure is the most effective stimulus in the internal medi-cine department, and bloodletting combined with paste and pressure in the surgery department, auricular point injection in the gynecology and pediatrics departments, bloodletting in the ophthalmology and otorhinolaryngology department, and auricular point incision in the dermatology department. Auricular point injection has remarkable effect. Bloodletting combined with paste and pressure has nearly the same effect as bloodletting in the same medical department except dematology department. Otherwise, angle of needling is rarely studied. CONCLUSIONS: Auricular therapy is widely used and has remarkable effect in treating diseases by using different stimulus modalities. Whereas the angle of needling is rarely studied and future investigation is needed.

Organic sunscreens continue to enter the environment through people's daily consumption, and become a kind of emerging contaminants. The photochemical degradation of benzophenone-3 (BP-3) in water by UV/H2O2 process was investigated. Several factors, including the initial BP-3 concentration, H2O2 concentration, UV light intensity, coexisting cations and anions, humic acid and tert-butyl alcohol, were also discussed. The results showed that BP-3 degradation rate constant decreased with increasing initial BP-3 concentration, while increased with increasing H2O2 dosage and UV intensity. Coexisting anions could reduce the degradation rate, while coexisting ferric ions could stimulate the production of OH through Fenton-like reaction, further significantly accelerated BP-3 degradation process. The BP-3 degradation would be inhibited by humic acid or tert-butyl alcohol. The electrical energy per order (E(Eo)) values were also calculated to evaluate the cost of BP-3 degradation by UV/H2O2 process. The addition of ferric ions significantly reduced the value of E(Eo). The investigation of processing parameter could provide a reference for the practical engineering applications of benzophenone compounds removal by UV/H2O2 process.

OBJECTIVE: To explore the regularities and features of clinical application of simplex reinforcing or reducing manipulation of filiform acupuncture needles by data mining in order to guide clinical decision in a better way. METHODS: A database about simplex reinforcing and reducing manipulations of filiform acupuncture needle was established first after collection, sorting, screening, type-in, and collation of the related papers, academic dissertations and theses of academic conferences published from January 1st of 1950 to January 31 of 2015 by using key word "acupuncture" "acupuncture and moxibustion" "needle manipulation" and "filiform needle" from database of China National Knowledge Infrastructure (CNKI, a full-text database of Chinese journals), followed by data extraction and statistical analysis. RESULTS: A total of 1 304 articles were found to meet the standards formulated in the present study. Among them, 800 papers belong to the internal medicine covering apoplectic sequelae (153 papers), apoplexy (52), headache (63) and insomnia (60), 271 to surgery involving soft tissue injury (63) and backleg pain (46); 93 to five-sense-organs involving nasosinusitis (14), 64 gynecology involving dysmenorrhea (13), 41 to dematology involving struma (20), and 35 to pediatrics covering five kinds of tardy growth and five flaccid syndromes(8). These 1 304 papers contain 2 542 of simplex reinforcing and reducing manipulations, including 895 of twirling-thrusting reducing, 611 of twirling-rotating reinforcing, 571 of lifting-thrusting reducing, 303 of lifting-thrusting reinforcing, 32 of reinforcing and 32 of reducing in cooperation wihpatients' respiration, 23 open-close reducing, 12 open-close reinforcing, 21 reducing and 16 of reinforcing achieved by inserting the needle along or against the meridian, 14 rapid-slow reinforcing, and 12 rapid-slow reducing. Regarding the acupoint selection, distal and local acupoints are most frequently used, followed by symptoms-determined and syndrome-determined, respectively. The acupuncture needle retained time was from 0 min to 45 mn, and the therapeutic effect was relatively better for post-stroke. The totally therapeutic effects of the simplex reinforcing and reducing manipulations were 96.07% for problems of demotology, 94.19% for gynecology, 96. 58% for surgery, 92.85% for pediatrics, 91.78% for five-sense organs and 93. 70% for internal medicine, respectively. CONCLUSION: Simplex reinforcing and reducing manipulations of acupuncture has a definite effect in the treatment of different problems particularly in the internal medicine and surgery. Often, the twirling-rotating and lifting-thrusting reinforcing and reducing manipulations of acupuncture are employed in clinical practice.

Restriction fragment length polymorphism (RFLP) technology was used to investigate the microbial diversity and structure of biological activated carbon (BAC) from different sources in drinking water advanced treatment process. Diversity indices of samples A, B and C, with relatively high tannic acid and humic acid adsorption capacity, were close to each other, which meant higher microbial diversity. However, samples D and E had relatively lower diversity indices with the low tannic acid and humic acid adsorption capacity. There were five species including ß-Proteobacteria, α-Proteobacteria, Planctomycetes, γ-Proteobacteria, Bacteroidetes in the phylogenetic tree of BAC samples. Among them, ß-Proteobacteria and α-Proteobacteria were the dominant microbial species in these BAC samples, which played an important role in organic matter removal. Planctomycetes, γ-Proteobacteria, and Bacteroidetes were the non-dominant microbial species. Bacteroidetes only existed in samples A, B, C and D, while did not occur in sample E. The BAC samples with the higher tannic acid and humic acid adsorption capacity had higher microbial diversity. This research should deepen the understanding of microbial community in BAC, and provide a theoretical basis for the safety of drinking water.
