Objective: To investigate the epidemiological characteristics of hand, foot, and-mouth disease (HFMD) among children under 6 years in Wuxing District, Huzhou City from 2013 to 2021, so as to provide insights into HFMC control among children. Methods : The surveillance on HFMD and enterovirus 71 (EV71) vaccination among children under 6 years in Wuxing District, Huzhou City from 2013 to 2021 were captured from China Disease Prevention and Control Information System, and the temporal, human and spatial distributions of HFMD cases and pathogenic detection results were descriptively analyzed. Results : A total of 14 272 HFMD cases under 6 years were reported in Wuxing District from 2013 to 2021, with an average annual incidence rate of 465.75/104. There were 8 313 male children with HFMD (522.39/104 incidence) and 5 959 female children with HFMD (404.55/104 incidence), and higher incidence of HFMD was seen among male children than among female children (χ2=239.228, P<0.001). Most HFMD cases were found among children at ages of 1 to 3 years (10 006 cases, 70.11%), and the incidence of HFMD peaked during the period between May and July and between October and December each year. High incidence of HFMD was seen in Zhili Township (741.50/104), Yangjiabu Street (546.99/104) and Balidian Township (438.68/104). There were 717 laboratory-confirmed HFMD cases (5.02%), including 106 EV71-positive cases (14.78%) and 177 CoxA16-positive cases (24.69%). A total of 56 288 doses of EV71 vaccines were administered in Wuxing District from 2017 to 2021, with an annual average full-dose vaccination rate of 14.87%. The detection of EV71 infection was significantly lower after EV71 vaccination than before vaccination (4.49% vs. 24.93%; χ2=62.932, P<0.001). Conclusions The incidence of HFMD peaks in summer and winter among children under 6 years in Wuxing District, which predominantly occurs among children at ages of 1 to 3 years. The incidence of HFMD is high in Zhili Township, Yangjiabu Street and Balidian Township, and the number of EV71-positive cases significantly reduces after EV71 vaccination than before vaccination.

BACKGROUND: The effects of low-level laser biostimulation have been proved by various experimental studies and clinical application, which are manifested as tissue repairing, analgesia, antiinflammation, etc.OBJECTIVE: To observe the effects of He-Ne laser and low-level CO2 laser irradiation on fracture healing.DESIGN: A randomized controlled animal experiment. SETTING: Research Room of Laser Medicine, Chengde Medical College.MATERIALS: Forty-eight healthy male New Zealand rabbits, weighing 2.0-2.5 kg, were used.METHODS: The experiments were carried out in the Research Room of Laser Medicine, Chengde Medical College from 1998 to 2003. ①The 48 rabbits were induced into models of experimental fracture of the left radius, and then they were divided into three groups with 16 rabbits in each group: control group, He-Ne laser irradiation group and CO2 laser irradiation group. The fracture areas of the animals in the He-Ne and CO2 laser irradiation groups were respectively irradiated with 28 mW/cm2 He-Ne laser and 150 mW/cm2 CO2 laser for 10 minutes, once a day. ② The animals were killed on the 15th and 35th days after taking roentgenogram respectively. At 15 days, the collagen and calcium contents in callus were detected. At 35 days, the biomechanic anti-torsion strength was examined.MAIN OUTCOME MEASURES: ①Results of roentgenogram in each group; ② Collagen and calcium contents in callus; ③ Results of biomechanic anti-torsion strength.RESULTS: Totally 45 rabbits were involved in the analysis of results. ① On the 15th and day after fracture, the roentgenogram, collagen and calcium contents in callus in the He-Ne and CO2 laser irradiation groups were better than those in the control group, and the collagen and calcium contents in callus were higher in the CO2 laser irradiation group than in the He-Ne laser irradiation group [(341.9±30.1) vs (302.1±28.7) mg/g; (197.1±19.7)vs (156.5±17.6) mg/g, P＜ 0.05]. ②On the 35th days after fracture, the biomechanic anti-torsion functions in the He-Ne and CO2 laser irradiation groups were superior to that in the control group, and there were no significant difference between the two laser irradiation groups. ③ The results of roentgenogram in the He-Ne and CO2 laser irradiation groups were better than that in the control group both on the 15th and 35th days after fracture, and there was no significant difference between the two irradiation groups.CONCLUSION: Both CO2 laser and He-Ne laser irradiations can accelerate the process of fracture healing, and the curative effect of CO2 laser is better than that of He-Ne laser on the 15th day after fracture, but there is no significant difference clinically between the CO2 laser and the He-Ne laser irradiations on the 35th day after fracture.

Objective: To investigate the relationship between type 2 diabetes mellitus (T2DM) and the pathogenesis and metastasis of colorectal cancer. Methods: A case-control study was performed to compare 852 colorectal cancer patients with 940 controls (patients without cancer) recruited from 2001 to 2006, with respect to their sex, cancer subsite, the course of T2DM, hepatic metastasis, smoking and drinking. Correlated risk factors were analyzed. Results: The risk of colorectal cancer was increased in patients with T2DM and the relative risk (OR) was 2.466. The OR of male patients was higher than that of female patients, but with no significant difference (2.775 vs 2.070, P=0.394). The incidence of T2DM in patients with left hemicolon cancer was higher than that in those with right hemicolon cancer and rectal cancer, but with no significant difference between them. The colorectal cancer risk in T2DM patients with a DM course of 10 ～ 20 years was the highest, and the OR was 4.696. The rate of hepatic metastasis was higher in T2DM patients with colorectal cancer than that in celorectal cancer patients without T2DM and the OR was 2.888. Conclusion: T2DM may be one of the important pathogenic risk factors for colorectal cancer. The OR is increased with the extension of DM course within 20 years. Colorectal cancer patients with T2DM may be more prone to hepatic metastasis.

Objective To investigate the clinical guiding significance of lymphoscintigraphy with 99mTc-DX for radical lateral lymph node dissection with pelvic autonomic nerve preservation(PANP) in lower rectal cancer.Methods In 67 patients with pathologically proven lower rectal cancer,37MBq/0.8ml 99mTc-DX was injected into submucosa of the rectum through rectal endoscopy.At 0.5h,1h,2h,3h,4h,6h,12h,and 24h after the injection,the patients underwent pelvic and lower abdominal lymphoscintigraphy. The operative method was determined according to the imaging results,and the results of lymphoscintigrams were correlated with postoperative lateral node histologic examination.Results The scintigrams were postive in 37 cases,and all were unilateral.The positive patients underwent PANP.The image results were compared with histological lymph node examination in all patients operated upon for rectal cancer.Histologically,the cases in conformity were 26(70.3 %),false positive in 11 cases(29.7 %),and 2 of 30 false positive patients who demonstrated metastases to lateral node were operated by PANP,while the others underwent only PANP(type Ⅰ) without lateral lymph nodes dissection.The percentage of good sexual function of the two groups of cases after operation was 74.4 % and 71.4 % respentively.The percentages of mild dysuria and good function of urination were both 100 %.Conclusions Lymphoscintigraphy with 99mTC-DX has particular guiding significance in selection of PANP for lower rectal cancer.
