Erectile dysfunction (ED) is prevalent among men, but its relationship with dietary habits is uncertain. The aim of our study was to assess whether dietary patterns enhance erectile function by reviewing the literature published before August 1, 2022, via PubMed, Web of Science, and EMBASE databases. The data compiled included author details; publication dates, countries, treatments, patient numbers, ages, follow-ups, and clinical trial outcomes, such as ED cases, odds ratios (ORs), confidence intervals (CIs), and International Index of Erectile Function-5 (IIEF-5) scores with means and standard deviations. An analysis of 14 studies with 27 389 participants revealed that plant-based diets (OR = 0.71, 95% CI: 0.66-0.75; P < 0.00001), low-fat diets (OR = 0.27, 95% CI: 0.13-0.53; P = 0.0002), and alternative diets such as intermittent fasting and organic diets (OR = 0.54, 95% CI: 0.36-0.80; P = 0.002) significantly reduced ED risk. High-protein low-fat diets (hazard ratio [HR] = 1.38, 95% CI: 1.12-1.64; P < 0.00001) and high-carb low-fat diets (HR = 0.79, 95% CI: 0.55-1.04; P < 0.00001) improved IIEF-5 scores. Combined diet and exercise interventions decreased the likelihood of ED (OR = 0.49, 95% CI: 0.28-0.85; P = 0.01) and increased the IIEF-5 score (OR = 3.40, 95% CI: 1.69-5.11; P < 0.0001). Diets abundant in fruits and vegetables (OR = 0.97, 95% CI: 0.96-0.98; P < 0.00001) and nuts (OR = 0.54, 95% CI: 0.37-0.80; P = 0.002) were also correlated with lower ED risk. Our meta-analysis underscores a strong dietary-ED association, suggesting that low-fat/Mediterranean diets rich in produce and nuts could benefit ED management.

ObjectiveWe aimed to investigate the efficacy and mechanism of Yishen Shengjing Prescription （YSP） in the treatment of oligoasthenospermia in rats. MethodThe oligoasthenospermia rat model was established by injection with cyclophosphamide （35 mg·kg^-1·d^-1） for 5 consecutive days. Rats were randomly assigned into control group （without treating with cyclophosphamide）， model group， low- （YSP-L）， medium- （YSP-M）， and high- （YSP-H） dose （2.91， 5.83， and 11.66 g·kg^-1， respectively） groups， Wuzi Yanzongwan （WYW， 1.03 g·kg^-1） group， and L-carnitine （0.17 g·kg^-1） group， with 8 rats in each group. After 28 days of drug intervention， the body weight， testicular weight， and testicular index of rats were recorded. The sperm quality in epididymis was detected by computer-assisted sperm analysis （CASA） system. Hematoxylin-eosin （HE） staining was employed for observation of testicular tissue morphology. The levels of malondialdehyde （MDA） and superoxide dismutase （SOD） in testicular tissue were detected by colorimetry. The levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and testosterone （T） in serum were determined by enzyme-linked immunosorbent assay（ELISA）. TdT-mediated dUTP nick-end labeling （TUNEL） was employed to detect the apoptosis of testicular cells. The protein levels of B cell lymphoma-2（Bcl-2）， Bax， and cleaved Caspase-3 in testicular tissue were detected by Western blot. ResultCompared with the control group， the model group showed decreased body weight， testicular weight and index， sperm concentration and motility （P<0.01） and increased testicular pathological score （P<0.01）. Compared with the model group， the YSP-M， YSP-H， WYW， and L-carnitine groups showed increased body weight， testicular weight， testicular index， sperm concentration and motility and decreased testicular pathological score. After modeling， the SOD level decreased （P<0.01） while the MDA content increased （P<0.01） in the testicular tissue. YSP-H， WYW， and L-carnitine reversed the SOD and MDA level changes caused by modeling. Compared with the control group， the model group exhibited declined T level （P<0.01） and increased FSH and LH levels （P<0.01）. Compared with the model group， YSP， WYW， and L-carnitine increased the T level （P<0.01） and decreased the LH level （P<0.05， P<0.01）. The apoptosis rate of spermatogenic cells in the model group was higher than that in the control group （P<0.01）， whereas YSP-M， WYW， and L-carnitine reversed such changes （P<0.01）. The model group rats showed decreased expression of Bcl-2（P<0.05） and increased expression of Bax and cleaved Caspase-3 （P<0.05， P<0.01）. Compared the model group， YSP-M， YSP-H， WYW， and L-carnitine up-regulated the Bcl-2 expression and down-regulated the cleaved Caspase-3 expression （P<0.05， P<0.01）. ConclusionYSP improved the sperm quality of oligoasthenospermia model rats by regulating the antioxidant system and sex hormone levels and inhibiting the apoptosis of spermatogenic cells.

Group A Streptococcus (GAS) is a very important pathogen, especially for children.On a global scale, GAS is an important cause of morbidity and mortality.But the burden of disease caused by GAS is still unknown in China and also has not obtained enough attention.For this purpose, the expert consensus is comprehensively described in diagnosis, treatment and prevention of GAS diseases in children, covering related aspects of pneumology, infectiology, immunology, microbiology, cardiology, nephrology, critical care medicine and preventive medicine.Accordingly, the consensus document was intended to improve management strategies of GAS disease in Chinese children.

Objective:To investigate the relationship between blood pressure variability (BPV) and incidence of post-traumatic stress disorder (PTSD) in trauma patients.Methods:Patients admitted to the department of emergency medicine of the Affiliated Hospital of Xuzhou Medical University for acute trauma from January 2018 to December 2021 were enrolled. The clinical data and blood pressure at admission (T1), 10 minutes before anesthesia (T2), 60 minutes after surgery (T3), and 24 hours after surgery (T4) were collected. Coefficient of variation of blood pressure variation [CV-BP, including coefficient of variation of systolic blood pressure (CV-SBP), coefficient of variation of diastolic blood pressure (CV-DBP), coefficient of variation of mean arterial pressure (CV-MAP)] and its quartile were calculated. Patients were divided into Q1 group (CV-MAP ≤ 7.27), Q2 group (7.27 < CV-MAP ≤ 9.50), Q3 group (9.50 < CV-MAP ≤ 14.05) and Q4 group (CV-MAP > 14.05) according to CV-MAP quartile. The PTSD symptoms of the patients were evaluated using the PTSD scale (PCL-5) one month later, and the patients were divided into the PTSD group and the non-PTSD group according to whether PCL-5 score higher than 38. Then the differences of the above indicators were compared and analyzed. Spearman correlation analysis was used to analyze the relationship between each index and PCL-5 score; the risk factors of PTSD were analyzed by univariate binary Logistic regression. Variables with P < 0.05 were included in the multivariate binary Logistic regression model. The receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of CV-MAP on the incidence of PTSD. Results:A total of 112 patients were enrolled, including 24 in PTSD group and 88 in non-PTSD group. Compared with non-PTSD group, the proportion of women, T1 shock index, proportion of intraoperative and postoperative blood transfusion in PTSD group was higher. Besides, PTSD group also had longer PT, more intraoperative and postoperative blood transfusion, and lower postoperative hemoglobin (Hb) level (all P < 0.05). The T1 SBP, DBP, MAP and T4 MAP of patients in PTSD group were significantly lower than those in non-PTSD group [T1 SBP (mmHg, 1 mmHg≈0.133 kPa): 105.0 (86.3, 121.3) vs. 122.0 (112.0, 132.8), T1 DBP (mmHg): 62.5 (50.0, 77.3) vs. 76.0 (68.5, 82.8), T1 MAP (mmHg): 77.8 (60.4, 91.3) vs. 93.3 (82.5, 99.0), T4 MAP (mmHg): 83.8±9.1 vs. 88.7±10.4, all P < 0.05], CV-SBP, CV-DBP and CV-MAP were higher than those in the non-PTSD group [CV-SBP: 12.80 (10.12, 19.16) vs. 9.30 (6.07, 12.95), CV-DBP: 16.62±6.47 vs. 12.40±5.61, CV-MAP: 14.10 (9.25, 18.85) vs. 8.90 (6.93, 13.29), all P < 0.05]. Spearman correlation analysis showed that there was a positive correlation between CV-MAP and PCL-5 scores in patients with acute trauma ( r = 0.429, P < 0.001); multivariate binary Logistic regression analysis showed that only CV-MAP [odds ratio ( OR) = 1.128, 95% confidence interval (95% CI) was 1.015-1.254, P = 0.025] and CV-DBP ( OR = 1.114, 95% confidence interval (95% CI) was 1.016-1.221, P = 0.022) was the risk factor for PTSD in acute trauma patients. Compared with Q1 group, Q4 group was significantly more likely to develop PTSD ( OR = 18.6, 95% CI was 1.9-179.1, P = 0.012). CV-SBP, CV-DBP and CV-MAP had certain predictive value on PTSD diagnosis in patients with acute trauma according to ROC curve analysis results [area under the ROC curve (AUC) was 0.713, 0.682 and 0.726, respectively], among which CV-MAP has the highest predictive value. When the cut-off value of CV-MAP was 12.158, the sensitivity was 75.0% and the specificity was 69.3%. Conclusion:Higher BPV after trauma is a risk factor for PTSD. Maintaining stable blood pressure in trauma patients is of great significance for prevention and treatment of PTSD.

【Objective】 To learn the production efficient of platelet components among prefecture-level blood stations in China, to provide supporting data for those blood stations to optimize the production mode of platelet components and continuously improve production efficiency and supply capacity. 【Methods】 The data from 2017 to 2020 was obtained from 24 prefecture-level blood stations who were the members of the practice comparison network for blood institutes in China. The collection units of apheresis platelets, the number of dual-collections of apheresis platelets and plasma, the average apheresis units of one platelet apheresis procedure, the discarded rate of apheresis platelets, the amount of expired apheresis platelets and the amount of apheresis platelets issued were collected. For concentrated platelets, the prepared amount of platelet concentrates and the amount of expired platelet concentrates were collected; both the quantity of qualified and issued concentrated platelets were submitted for statistical analysis.The total output and efficiency of platelet components were calculated based on the collected data. 【Results】 The average annual growth rate of apheresis platelets collection in 24 prefecture-level blood stations was 12.23%, accounting for 99.80% of the total platelet output; the average collection unit of one platelets apheresis procedure was 1.75; from 2019 to 2020, only 5 blood stations performed dual-collection of platelet and plasma during one apheresis procedure; the discarded rate of apheresis platelets was 0.28%, of which 0.007% was due to expiration. A total of 1 621.2 therapeutic units of concentrated platelets were prepared, and 13.03% of them was discarded due to the expiration. The production efficiency of platelet components was 97.56%, of which the production efficiency of apheresis platelets was 97.61% and the production efficiency of concentrated platelets was 74.43%. 【Conclusion】 There are large regional differences in the supply capacity of platelet components in prefecture-level blood stations. Apheresis platelets are the main resource of platelet components product, and the collection capacity is increasing over the years with the characteristics of high production efficiency and low expiration scrapping rate. However, the preparation of concentrated platelets are still limited with relatively low production and high expiration discarded rate.

Objective:To evaluate the intervention effects of aquatic therapeutic exercise on functioning and quality of life for children and youth with cerebral palsy within framework of World Health Organization Family International Classifications using systematic review. Methods:Literatures were retrieved and reviewed from the databases of Cochrane Library, PEDro, PubMed, EMBASE, Web of Knowledge, Web of Science, OVID, EBSCO, CMCI, CNKI, Wangfang and VIP until May, 2020.

Objective:To evaluate the analgesic effects of Wenjing Zhitong prescription （WZP） and explore its possible analgesic mechanisms so as to provide experimental basis for research and development of new Chinese medicine. Method:Analgesic effects of WZP were evaluated by observing the writhing latency and number in the writhing models which were induced by oxytocin in rats as well as those induced by acetic acid and prostaglandin E₁ （PGE₁）， respectively in mice. Effect of WZP on uterine contraction frequency， amplitude and activity were evaluated by observing the oxytocin-induced contraction of uterine smooth muscle in rats and rabbits in vivo. In the oxytocin-induced rat writhing models， the content of prostaglandin F_2α （PGF_2α） and prostaglandin E₂ （PGE₂） in rat uterine tissues and the content of beta-endorphins （β-EP） in rat serum were detected by enzyme-linked immunosorbent assay （ELISA）. Expression of estrogen receptor （ER） and oxytocin receptor （OTR） in rat uterine were tested by Real-time polymerase chain reaction（Real-time PCR） method to investigate the possible molecular mechanism of WZP for its analgesic effect. Result:Results of analgesic effect showed that in oxytocin-induced rat writhing experiment， the number of writhing responses in both the WZP （1.5，3.0 g·kg^-1） group was lower than than in the model group （P<0.05）. In acetic acid-induced mice writhing experiment， the latency of writhing response in WZP （6.0 g·kg^-1） group was significantly prolonged as compared with that in model group （P<0.01）， and the number of writhing response was significantly reduced （P<0.05）. In PGE₁-induced mice writhing model， the writhing number in WZP （1.5，3.0，6.0 g·kg^-1） groups was significantly lower than that in the model group （P<0.05，P<0.01）. Results of effect on uterine smooth muscle demonstrated that WZP （0.38，0.75，1.50 g·kg^-1） could significantly reduce the frequency of uterine smooth muscle contraction in rabbits （P<0.05，P<0.01）， WZP （0.75，1.50，3.00 g·kg^-1） could significantly reduce the contractile amplitude and activity of smooth muscle in the uterus of rats （P<0.05）. Results of molecular mechanisms of analgesic effects showed that the WZP （0.75，1.50，3.00 g·kg^-1） significantly reduced the content of PGF_2α and the ratio of PGF_2α to PGE₂ in the uterine tissue of rats （P<0.01）. In the WZP （3.00 g·kg^-1） group， the levels of β-EP in the serum of rats were significantly increased （P<0.01）， and the levels of OTR in uterus of rats in the WZP （1.50，3.00 g·kg^-1） group were significantly decreased （P<0.05）. Conclusion:Pharmacological studies demonstrated potent analgesic effect of WZP， and such analgesic effect were mediated by significantly inhibiting contraction of uterine smooth muscle， decreasing the contents of PGF_2α and ratio of PGF_2α/PGE₂， reducing OTR expression in uterine as well as increasing the amount of β-EP in serum.

Objective: To observe the efficacy of long-retaining scalp acupuncture plus interactive training in improving upper- extremity dysfunction in cerebral stroke patients. Methods: Ninety-five patients with upper-extremity dysfunction after cerebral stroke were randomized into two groups, with 48 cases in the treatment group and 47 cases in the control group. Conventional internal medicine treatment was offered to both groups. In both groups, Anterior Oblique Line of Vertex-temporal (MS 6, the middle 2/5) and Posterior Oblique Line of Vertex-temporal (MS 7, the middle 2/5) were selected from the same side of the brain lesion (the side apposing to the hemiplegic limb) for scalp acupuncture treatment. In the treatment group, the scalp acupuncture needles were retained for 7 h, in combination with interactive training, while the needles were also retained for 7 h in the control group but without interactive training. Prior to treatment and at 2-week and 4-week treatment, the two groups were scored using the functional test for the hemiplegic upper extremity-Hong Kong (FTHUE-HK) and simplified Fugl-Meyer assessment-upper extremity (FMA-UE). Results: The total effective rate was 97.9％ in the treatment group, higher than 74.5％ in the control group (P<0.01). The FTHUE-HK score was higher at 2-week and 4-week treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FTHUE-HK score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FTHUE-HK score was higher in the treatment group than in the control group, showing significant between-group differences (both P<0.05). During the whole treatment process, the treatment group had higher FTHUE-HK scores compared with the control group, but there was no statistical significance comparing the change of the score between the two groups at 2-week treatment (P>0.05), while the between-group difference in the change of the score was statistically significant at 4-week treatment (P<0.05). The FMA-UE score was higher at 2-week and 4-weeks treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FMA-UE score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FMA-UE was higher in the treatment group than in the control group, and the between-group differences were statistically significant (both P<0.01). The FMA-UE score rose gradually with the increase of treatment session, and there was statistical significance comparing the change of the score between the two groups at 2-week and 4-week treatment, respectively (both P<0.05). Conclusion: Long-retaining scalp acupuncture plus interactive training results in more significant efficacy than long-retaining scalp acupuncture alone in improving the upper-limb dysfunction after cerebral stroke and the advantage becomes more notable after 2-week consecutive treatment.
