BACKGROUND: Traditional repair for Achilles tendon rupture has disadvantages of long cast immobilization times, poor outcomes and many complications.OBJECTIVE: To explore the safety and efficacy of early isokinetic rehabilitation training for patients after repair of Achilles tendon ruptures.METHODS: A total of 11 patients with Achilles tendon ruptures received treatments at the Department of Orthopedics, East District of Qingdao Municipal Hospital, from September 2007 to September 2009, were included. Nine of them underwent 8-week isokinetic exercises by using lsomed-2000 at 4 weeks after tendon repair. The evaluative indicators included Arner-Lindholm score, the ankle range of motion, and extensor-flexor peak torque.RESULTS AND CONCLUSION: The follow-up averaged 6 months, ranging from 3 to 12 months. The excellent and good rate of Arner-Lindholm score was 88.9%. The results showed a significant improvement in the ankle range of motion and extensor-flexor peak torque (P < 0.05). There were no infection or re-rupture cases. It is indicated that early isokinetic rehabilitation is safe and effective for patients with Achilles tendon ruptures at 4 weeks postoperatively. It provides evidence for early rehabilitation in patients with Achilles tendon ruptures.

Objective : To investigate the fertility level of registered population in Baoshan District, Shanghai Municipality and the incidence of adverse birth outcomes of live births from 2013 to 2022, so as to provide the evidence for improving maternal and child health care strategies. Methods: The data pertaining to live births registered in Baoshan District from 2013 to 2022 were collected through the Shanghai Birth Medical Information System, including the basic information of live births and maternal fertility. The indicators such as fertility level, parity, birth age and incidence of adverse birth outcomes of live births were descriptively analyzed. The trend of crude birth rate and total fertility rate was analyzed by annual percent change (APC). Results: A total of 56 719 live births were registered in Baoshan District from 2013 to 2022. The crude birth rate was 6.54‰, the total fertility rate was 31.78‰, and the sex ratio at birth was 105.61. The crude birth rate showed a downward trend from 2016 to 2022 (APC=-11.054%, P<0.05), and the total fertility rate showed a downward trend from 2017 to 2022 (APC=-10.377%, P<0.05). The proportion of second parity and above showed an increasing trend from 2013 to 2017 (P<0.05) and a decreasing trend from 2017 to 2022 (P<0.05). The maternal childbearing age showed an increasing trend from 2013 to 2022 (P<0.05), the incidence of premature infants and low birth weight infants showed an increasing trend (both P<0.05). The incidence of premature infants and low birth weight infants increased with the rising childbearing age (both P<0.05). Conclusions The fertility level in Baoshan District was relatively low from 2013 to 2022. The proportion of second parity and above showed an upward trend followed by a downward trend. The incidence of premature infants and low birth weight infants increased with the rising childbearing age.

Results After treatment, the scores of activity restriction and the total score of SGRQ in the experiment group improved more than that in the control (P<0.05). Conclusion Self-management is important for improving quality of life in stable COPD.

Objective To establish a high-throughput evaluation model for anaphylactic reactions; To screen and identify potential anaphylactogens from TCM monomeric compounds.MethodsCell model of stably expressed MrgX2 was established. Recombinate plasmid pmCherry-C1-MrgX2 was transfected to HEK293 to establish cell line for screening model. MrgX2 agonist and antagonist were used to identify the validation and stability of the cell line. A small library consisting of 180 compounds was profiled by using a cell-based calcium mobilization assay to find novel compounds targeting the MrgX2 receptor. EC50 test, IC50 test, specificity validation and cytotoxicity evaluation were carried out to detect the function of the positive agonist.ResultsThe EC50 of C48/80 to MrgX2 model was 2.7 μg/mL and the IC50 of 2-APB (evoked by 10 μg/mL C48/80) was 46.29 μmol/L. The first generation cell model of MrgX2 was similar to the 20th generation, and the Z factor of MrgX2 cell model was 0.78. In the primary screening for agonist, isoliensinine was identified as a novel agonist targeting receptor MrgX2 with an EC50 of 4.5 μmol/L and IC50 of39.47 μmol/L. Moreover, isoliensinine was validated to activate MrgX2 receptor specifically without cytotoxicity. Conclusion A high-throughput evaluation method for anaphylactic reactions can be established in vitro through calcium mobilization assay. A potential anaphylactogen isoliensinine is identified and validated.

A collection of 57 natural compounds derived from Chinese herbal medicines were evaluated for their an-ti-adipogenic effects. The lipid droplets in differentiated 3T3-L1 adipocytes treated with tested substrate were de-tected by an image-based assay. The results demonstrated that oleanolic acid (OA) inhibited lipid droplets accumula-tion in 3T3-L1 adipocytes in a dose-dependent manner with the IC50 value of 14.5 μmol·L-1. In addition, ToxInsight assay showed that OA was free of liver injury for HepG2 cells within 60 μmol·L-1. It was concluded that OA, which had an obvious anti-adipogenic effect, can be a candidate for hyperlipidemia therapy.

Objective: To analyze the results of colorectal cancer screening among residents in Baoshan District, Shanghai Municipality from 2013 to 2021, so as to provide the basis for promoting colorectal cancer screening and prevention. Methods: Permanent residents aged 50 to 74 years in Baoshan District from 2013 to 2021 were selected as the screening population. The initial screening was conducted using a risk assessment form and fecal occult blood test. Positive results on either the risk assessment form or fecal occult blood test were considered positive for the initial screening. Participants with positive initial screening results were invited to undergo colonoscopy. The positive rate of the initial screening, colonoscopy compliance rate, and colonoscopy results were analyzed. Results: A total of 264 907 individuals underwent the initial colorectal cancer screening in Baoshan District from 2013 to 2021, with 65 333 individuals (24.66%) testing positive. Among them, the positive rate of the risk assessment form was 12.16%, and the positive rate of fecal occult blood test was 14.64%. A total of 14 473 individuals completed colonoscopy, with a compliance rate of 22.15%. A total of 1 284 precancerous lesions were detected, with a detection rate of 8.87%, and 386 cases of colorectal cancer were identified, with a detection rate of 2.67%. The positive rate of the initial screening, colonoscopy compliance rate, precancerous lesion detection rate, and colorectal cancer detection rate were higher in males than in females (25.55% vs. 24.06%, 23.12% vs. 21.45%, 11.60% vs. 6.74%, 3.62% vs. 1.93%, all P<0.05). With increasing age, the positive rate of the initial screening increased, the colonoscopy compliance rate decreased, the precancerous lesion detection rate and colorectal cancer detection rate increased (all P<0.05). From 2013 to 2021, the positive rate of the initial screening among residents showed a downward trend, while the colonoscopy compliance rate showed an upward trend (both P<0.05). Conclusions The detection rate of precancerous lesions in colorectal cancer was 8.87%, and the detection rate of colorectal cancer was 2.67% in Baoshan District from 2013 to 2021.

Objective: To explore the spatial-temporal distribution and epidemic characteristics of hemorrhagic fever with renal syndrome (HFRS) in Hebei province from 2005 to 2016. Methods: Records of HFRS cases reported from each county in Hebei during January 2005 to December 2016 were collected from National Notifiable Disease Surveillance System (NNDSS). Global and local spatial association statistics were used to measure the spatial autocorrelation and software GeoDa 1.2.0. Software SaTScan 9.4.1 was used to analyze spatiotemporal clusters. Software ArcGIS 10.2 was used to visualize the yearly scan results. Results: In Hebei province, a total of 8 437 human HFRS cases reported from 170 counties with an annual incidence rate of 0.99/100 000 population during 2005-2016. The peak incidence season was spring. Global spatial autocorrelation analysis on the incidence of HFRS at county-level showed that the value of Moran’s I were all above 0 (P<0.05), indicating that the significant spatial cluster. The result of local indicators on spatial association (LISA) analysis revealed that identified hot spots were mainly in northeastern area, while cold spots were found in some counties of central and southern areas. Spatial-temporal scan detected that the primary cluster of HFRS incidence was mainly distributed in Qinhuangdao city and Tangshan city, including 11 counties (city/district): Beidaihe district, Haigang district, Funing district, Shanhaiguan district, Changli county, Lulong county and Qinglong Manchu autonomous county in Qinhuangdao city, and Qian’an city, Laoting county, Luanzhou city and Luannan county in Tangshan city (RR=39.64, P<0.001), during January-July in 2005. Conclusions There were significant spatial-temporal cluster of HFRS in Hebei from 2005 to 2016. The cluster areas of HFRS were mainly in northeastern Hebei, it is necessary to strengthen the prevention and control programs of HFRS in these areas.

Objective To discuss the relationship and clinical significance between anterior rectocele and resultant constipation by the obstruction of functional outlet. Methods The clinical and dynamic defecography materials of 417 cases with resultant constipation by the obstruction of functional outlet were retrospectively reviewed. Dynamically replaying the cases of anterior rectocele and analyzed the representation. Results ①310 cases with anterior rectocele,392 cases with internal rectal prolapse,353 cases with perineum descending,69 cases with pelvic spasm or puborectalis thickening. 95.20% (397/417) cases with more than 2 abnormalities simultaneously,no cases with only anterior rectocele. The difference between men and women was statistically significant(P< 0.01) of anterior rectocele,perineum descending、pelvic spasm or puborectalis thickening. There was no difference with internal rectal prolapse(P> 0.05). ②Dynamically replaying the cases of anterior rectocele:226 cases could drain almost all of the barium of rectum and the distal rectum mucosal fold hypertrophy,account for 72.90% (226/310);71 cases could not drain any or drained driply and prolapse of rectal mucosa or pelvic spasm or puborectalis thickening,account for 22.90% (71/310); 13 cases with protruded sac reduced not obsolete and rearward the sac internal rectal prolapse, account for 4.20% (13/310). Conclusion Anterior rectocele is not the main cause of constipation,to make sure the relationship between anterior rectocele and resultant constipation by the obstruction of functional outer can provide instructional significance for the cure scheme.

ObjectiveTo investigate the epidemiological characteristics of respiratory disease mortality in Baoshan residents during the period of 2009‒2020. MethodsRespiratory disease deaths of Baoshan residents from 2009‒2020 were collected. ICD-10 codes were used to classify the causes of death， and R-4.2.1 was applied for statistical analysis. The average annual percent change （AAPC） of standardized mortality rates of different respiratory diseases were analyzed by using Joinpoint 4.9.0.0. ResultsThe average annual mortality rate of respiratory diseases in Baoshan from 2009 to 2020 was 58.86/10⁵， and the standardized mortality rate was 35.62/10⁵， which was the 3rd leading cause of mortality. The mortality rate of respiratory diseases was higher in men than in women （χ²=46.70， P<0.001）. COPD ranked first among respiratory diseases in Baoshan from 2009 to 2020， followed by pneumonia， asthma and pneumoconiosis in that order. The standardized mortality rate for COPD decreased from 38.66/10⁵ in 2009 to 19.88/10⁵ in 2020 （AAPC=-6.6%， 95%CI： -8.2% to -4.9%， P<0.001）.
