Objective To evaluate the effect of vacuum sealing drainage(VSD)ON the destroyed hand injuries.Methods From January 2006 to December 2008,forty pafients with destroyed hand injuries (surface of wound)were randomly divided into VSD group(20 cases)and control group(chlorhexidine wet compress)(20 cases)after debridement. The outcomes were retrospectively analysed by pain score,swelling score,bacterial positive rate and necrotic tissue.Results Three days after treatment,the pain score of VSD group was(2.62±1.54)degree,and that of control group was(3.39±1.64)degree.There wag significant difference between the two groups(P＜0.01).The swelling score of VSD group was(1.51±0.25)degree which was different from control group(2.29±1.26)degree(P＜0.05).The bacterial positive rate of control group was 20%(4/20),but that of VSD group was 5%(1/20).There was significant difference between the two groups(P＜0.05).The VSD group had no necrotic tissue occurrence,but the control group had 2 cases,one of which had serious necrosis and had escapology.Conclusion VSD Can inhibit bacterial infection,ease pain,exempt changing dressings and stimulate growing of granulation tissue also can maintain a good environment for tissue transplantation later.So VSD combining with tissue transplantation is an ideal therapy in destroyed hand injuries.

Objective:To explore influence of diltiazem hydrochloride on expression of serum microRNA in aged pa‐tients with dilated cardiomyopathy (DCM ) . Methods :A total of 120 aged DCM patients (DCM group ) and 60 healthy aged people (normal control group) were enrolled .DCM group was further randomly and equally divided in‐to routine treatment group (n=60) and diltiazem group (n=60 ,received additional diltiazem hydrochloride based on routine treatment) .Left ventricular end -diastolic dimension (LVEDd) ,left ventricular posterior wall thickness (LVPWT) and left ventricular ejection fraction (LVEF) were observed and compared between routine treatment group and diltiazem group before and after treatment ,cardiac function improvement was compared between these two groups after treatment .Changes of expression amount of serum miR -1 ,-133 ,-499 and -208 were com‐pared among three groups before ,six and 12 weeks after treatment .Results:Compared with before treatment ,after treatment ,there were no significant changes in LVEDd ,LVPWT and LVEF in routine treatment group , P>0.05 all;there were significant reductions in LVEDd [(69.41 ± 6.42) mm vs .(61.32 ± 5.31) mm] and LVPWT [(20.98 ± 1.98) mm vs .(12.05 ± 2.42) mm] and significant rise in LVEF [(32.81 ± 4.71)% vs .(50.52 ± 6.88)% ] in dilt‐iazem group , and LVEDd , LVPWT were significantly lower than those of routine treatment group [LVEDd:(67.25 ± 4.21) mm ,LVPWT :(18.49 ± 2.86) mm] ,and LVEF was significantly higher than that of routine treat‐ment group [ (47.77 ± 3.92)% ] , P<0.05 all .For cardiac function improvement ,markedly effective rate (71.7%vs .56.7% ) and total effective rate (98.3% vs .85.0% ) of diltiazem group were significantly higher than those of routine treatment group , P<0.05 both . Compared with normal control group , the 4 kinds of miR expression sig‐nificantly reduced in routine treatment group , and compared with routine treatment group , those of diltiazem group were significantly rose , P<0.01 all , but compared with 6‐week , miR expression had downtrend during 12‐week , the miR‐208 expression was most significant ( P< 0.01 ) .Conclusion:Diltiazem could effectively modulate serum microRNA expression in aged CDM patients ,which provided molecular biological basis for studying diltiazem mech‐anism .

Objective To observe the curative effect of pricking bloodletting combined with acupuncture on patients with piriformis injury syndrome.Methods A prospective randomized controlled clinical trial was conducted, 84 patients with piriformis injury syndrome admitted to the Department of Acupuncture and Massage in the First Affiliated Hospital of Xinjiang Medical University from May 2011 to May 2014 were enrolled, and they were divided into observation group and control group by random number table, each group being 42 cases. The patients in the observation group were treated with bloodletting once a week (after bloodletting no other treatment was given), and then once a day of acupuncture was performed for 4 days in a week, completing one therapeutic course; while in the control group, the patient was treated with routine acupuncture once a day for 5 days in a week, finishing one therapeutic course. The interval between two therapeutic courses was 2 days, two courses were carried out, and afterwards the clinical therapeutic effects were evaluated in the two groups. The changes of visual analogue scale (VAS) of two groups before and after treatment and the therapeutic effects were observed.Results The VAS score of the two groups after treatment was lower than that before treatment, and the degree of decrease of VAS score in the observation group was significantly lower than that of thecontrol group (1.50±1.35 vs. 2.69±1.68,P < 0.01); the total effective rate in the observation group was obviously higher than that in the control group [100.00% (42/42) vs. 69.05% (29/42),P < 0.01].Conclusion Pricking bloodletting combined with acupuncture therapy for treatment of piriformis injury syndrome can shorten the course of treatment.

Objective: To investigate the gravity center and spatial clustering of silicosis in Zhejiang Province, so as to provide the reference for improving silicosis prevention and control measures. Methods: Data on cases of silicosis in Zhejiang Province from 2013 to 2022 was collected from the National Occupational Disease and Health Risk Factors Monitoring Information System. The spatial and temporal characteristics of silicosis incidence in Zhejiang Province were analyzed using the gravity center migration and spatial autocorrelation analysis. Results: Totally 2 902 silicosis cases were reported in Zhejiang Province from 2013 to 2022. The reported cases in 2013, 2019 and 2014 ranked the top three, with 545 (18.78%), 373 (12.85%) and 372 (12.82%) cases, respectively. The silicosis cases were predominantly males, accounting for 99.04% (2 874 cases). The main occupation was mining and related industries, accounting for 50.41% (1 463 cases). Gravity migration analysis showed that the gravity center of silicosis incidence was in Shengzhou City in 2013; from 2014 to 2018, it migrated to the southwest, and was located in Dongyang City and Yiwu City; from 2019 to 2020, it migrated to the southeast, and was located in Xianju County and Tiantai County; then from 2021 to 2022, it migrated to the west, and was located in Pan'an County and Xianju County. Spatial autocorrelation analysis showed that there was spatial correlation of silicosis incidence in 2014, 2016, and 2021 (all Moran's I >0, all P<0.05). Ningbo City, Quzhou City, Wenzhou City and Taizhou City were high-high clustering sites. Conclusions The gravity center of silicosis incidence in Zhejiang Province from 2013 to 2022 had a slight migration, and mainly gathered in the central regions. The high-high clustering sites were migrated from Ningbo City and Quzhou City to Taizhou City.
