Objective To examine the impact of psychosocial factors on physical activity,so as to provide guidance for the development of an effective physical activity intervention program for individuals with hypertension.Methods This study used a baseline data from an intervention study on regular physical activity among hypertensive individuals.A multi-stage,stratified random sampling was utilized and finally 12 communities from 6 urban districts were chosen.Questionnaires were administrated through face-to-face interviews.A total of 586 participants were recruited and finally 559 completed the interviews with the response rate as 95.4％.Descriptive statistics and Cronbach' sα coefficients were used to test the reliability.General Linear Model analysis was used to analyze the relationship between stages of physical activity and psychological factors.Results Psychosocial measures on physical activity demonstrated good reliability with Cronbach α coefficient from 0.7 to 0.9.The scores for each psychological measures increased by increasing the scores of stages of physical activity.General Linear Model analysis revealed self-efficacy (β=0.379) while enjoyment of physical activity (β =0.234) was significantly correlated with physical activity (P＜0.05).The behavioral processes and family support marginally increased the physically activity (β =0.069 for behavioral processes and β=0.163 for family support,P＜0.10).Conclusion Our findings were informative for the development of community-based intervention programs on physical activity among hypertensive individuals.It indicated that physical activity intervention programs should be psychosocial theory-based,especially increasing their self-confidence and enjoyment,as well as with family support,in order to adopt and maintain the physical activities.

OBJECTIVETo investigate the effective therapeutic method of human cytomegalovirus (HCMV) hepatitis in children.

METHODSTwenty-five children with HCMV hepatitis were randomly assigned to a treated group (n=13) or a control group (n=12). Both groups were treated with prednisone, glucurone, luminal and Xiaoyanlidanpian. But the treated group was given ganciclovir (GCV) + intravenous immunoglobulin (IVIG) in addition. Each infant of the two groups was checked for blood routine, liver function and HCMV copy numbers on admission and before discharge. They were seen at the third, sixth and ninth month after discharge. On each visit blood specimens were collected for HCMV copy numbers (fluorescence quantitative PCR, FQ-PCR).

RESULTSThe viral load of the treated group decreased significantly. A significant difference in viral copy numbers was found between the two groups on admission, discharge, and third, sixth and ninth month after discharge (P less than 0.001). The number of HCMV DNA copy fell to 10(3) copies/ml on discharge while that of the control group fell to the same level after the third month. The differences between the two groups in the length of hospitalization, time of initial jaundice disappearance and complete disappearance were statistically significant (P less than 0.05). The need for transfusion in the treated group was significantly less than that in the control group (chi-square=4.012, P less than 0.05).

CONCLUSIONCombination of GCV with a high dosage of IVIG to treat HCMV active infection could decrease viral load remarkably; The duration of disease, severity of symptoms, degree of anemia and the need for blood transfusion were reduced. No adverse effects related to the combination of GCV with IVIG therapy were observed.

The prevalence of Toxoplasma gondii infection in birds has epidemiological significance because birds are indeed considered as a good indicator of environmental contamination by T. gondii oocysts. In this study, the prevalence of T. gondii in 313 house sparrows in Lanzhou, northwestern China was assayed by the modified agglutination test (MAT). Antibodies to T. gondii were positive in 39 (12.46%) of 313 samples (MAT titer > or = 1:5). Tissues of heart, brain, and lung from the 39 seropositive house sparrows were tested for T. gondii DNA, 11 of which were found to be positive for the T. gondii B1 gene by PCR amplification. These positive DNA samples were typed at 9 genetic markers, including 8 nuclear loci, i.e., SAG1, 5'- and 3'-SAG2, alternative SAG2, SAG3, GRA6, L358, PK1, c22-8 and an apicoplast locus Apico. Of them, 4 isolates were genotyped with complete data for all loci, and 2 genotypes (Type II variants; ToxoDB #3 and a new genotype) were identified. These results showed that there is a potential risk for human infection with T. gondii in this region. To our knowledge, this is the first report of T. gondii seroprevalence in house sparrows in China.

Mercury sphygmomanometer based on traditional auscultation method is widely used in primary medical institutions in China, but a large amount of blood pressure data can not be directly recorded and applied in scientific research analysis, meanwhile auscultation data is the clinical standard to verify the accuracy of non-invasive electronic sphygmomanometer. Focusing on this, we designed a miniature non-invasive blood pressure measurement and verification system, which can assist doctors to record blood pressure data automatically during the process of auscultation. Through the data playback function,the software of this system can evaluate and verify the blood pressure algorithm of oscillographic method, and then continuously modify the algorithm to improve the measurement accuracy. This study introduces the hardware selection and software design process in detail. The test results show that the system meets the requirements of relevant standards and has a good application prospect.

【Objective】To evaluate the feasibility of magnetization transfer（MT）magnetic resonance（MR）imaging for predicting the risk of intestinal fistula in patients with Crohn disease （CD）. 【Methods】 The study prospectively enrolled 12 consecutive patients with CD and abdominal MT imaging were performed before elective surgery. The bowel wall MT ratio normalized to skeletal muscle was calculated；region- by- region correlations with the surgical specimen were performed. Histopathologic evaluation of fibrosis was executed by using Masson trichrome. Wilcoxon rank test ， Spearman rank correlation， and receiver operating characteristic curve （ROC） were used for statistical analysis.【Results】Among 15 surgical intestinal segments from 12 patients，5 lesions were found with intestinal fistula and of them 12 bowel specimens were obtained. The other 10 intestinal segments were without complications and 23 bowel specimens were enrolled. The intestinal fistula bowel showed a significant higher （P=0.045） normalized MT ratio. ROC analysis revealed an area under the curve of 0.674（95%CI：0.537-0.811）for differentiating intestinal fistula bowel from the non- fistula one. The sensitivity，specificity was 93.3% and 51.1% with a cut-off value of 76.8%，respectively. For the Masson score，significant difference（P=0.012）was found between the complicated intestinal specimens and the non-complicated ones. Additionally， the normalized MT ration was statistical correlated with Masson score （r=0.708，P<0.001）.【Conclusion】MT imaging could be a potential method to predict the risk of intestinal fistula in patients with CD.

Qizhu, the dried rhizome of Atractylodes macrocephala in Compositae family, is the representative wild variety of Atractylodis Macrocephalae Rhizoma (Baizhu) with modern excellent quality. Through textual research of materia medica works and modern studies, the medication methods between Qizhu and ancient Baizhu were systematically compared. Focusing on seven key issues, this paper systematically summarized the medicinal history, characters, cultivation and other related contents of Qizhu, in order to provide a basis of Qizhu in the recovery and development of its own Daodi-status, and further serve the industrial development of this herb. The name, harvesting time, processing method and other issues had undergone a relatively complicated evolution process. At present, acknowledged points are as following：①The distribution areas of Qizhu include southern areas of the Yangtze River in Anhui province and its surrounding regions. ②Harvesting time is late October. ③Qizhu can be dried in the shade or micro-hot dried after being wrapped with absorbent paper, later it can be divided into two commercial specifications. ④In addition to cutting, there is still a lack of other processing methods. ⑤The superior characters of Qizhu contain white, less oil, fragrant smell and sweet taste and so on. ⑥The history of Qizhu as a genuine medicinal material can be traced back to the Ming dynasty.

OBJECTIVE: To observe the clinical effect of high suspension and low incision (HSLI) surgery on mixed haemorrhoids, compared with Milligan-Morgan haemorrhoidectomy. METHODS: A multi-centre, randomized, single-blind, non-inferiority clinical trial was performed. Participants with mixed haemorrhoids from Xiyuan Hospital of China Academy of Chinese Medical Sciences, Beijing Rectum Hospital, Air Force Medical Center of People's Liberation Army of China, and Puyang Hospital of Traditional Chinese Medicine were enrolled from September 2016 to March 2018. By using a blocked randomization scheme, participants were assigned to two groups. The experimental group was treated with HSLI, while the control group was treated with Milligan-Morgan haemorrhoidectomy. The primary outcome was the clinical effect evaluated at 12 weeks after operation. The secondary outcomes included the number of haemorrhoids treated during the operation, pain scores, use of analgesics, postoperative oedema, wound healing, incidence of anal stenosis, anorectal manometry after operation, as well as surgical duration, length of stay and total hospitalization expenses. A safety evaluation was also conducted. RESULTS: In total, 246 eligible participants were enrolled, with 123 cases in each group. There was no significant difference in the clinical effect between the two groups (100.00% vs. 99.19%, P>0.05). Compared with the control group, the number of external haemorrhoids treated during the operation and the pain scores after operation were significantly reduced in the experimental group (P<0.05 or P<0.01); the patient number with wound healing at 2 weeks after operation and the functional length of anal canal at 12 weeks after operation were significantly increased in the experimental group (P<0.05). There was no significant difference in the incidence of anal stenosis, the numbers of patients using analgesics and patients with postoperative oedema between the two groups after operation (P>0.05). The surgical duration and length of stay in the experimental group were significantly longer than those in the control group, and the total hospitalization expense was significantly higher than that in the control group (all P<0.05). No adverse events were reported in either group during the whole trial or follow-up period. CONCLUSION HSLI had the advantages of preserving the skin of anal canal completely, alleviating postsurgical pain and promoting rapid recovery after operation. (Registration No. ChiCTR1900022883).

Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.
