Isothiazolone exhibit a broad-spectral antiseptic actions. The formalin fixed cadavers preserved in 0.1％ isothiazolone aqueous solution for 3 years, revealed that the solution still kept clear, and the colour of the cadavers was well retained, and the gross structure of the cadavers was in good condition. Bacteriostatic test indicated that 0.05-0.1％ isothiazolone solution was highly effective in inhibiting common septic bacteria and fungi, and was reliably effective in inhibiting the aspergillus flavus taken from the surface of the midewy cadavers. The chemical property of the isothiazolone solution was stable, and its T_(1/2) was 93.28 months, and the bacteriostatic effect might keep for 7 years. The solution was colourless, odorless and nonirritant. Toxicity test revealed its LD_(50) was 175mg/kg, and the Ames' mutation test showed a negative result, and the teratologic study indicated that it did not induce any skeletal malformations in neonatal rats. This study suggest that 0.1％ isothiazolone may be used as a preservative to substitute for formaldehyde.

Objective To analysis complications and its associated risk factors of high intensity focused ultrasound (HIFU) in treatment of uterine leiomyoma for selecting rationale indicated patients and reducing complications. Methods Medical documents of 171 patients with 231 leiomyomas in total treated by HIFU were studied retrospectively. Common complications were categorized and analyzed, the relationship between risk factors and complications were studied. Results Common complications in treatment of uterine leiomyomas by HIFU were 71.9% (123/171) of abdominal pain, 17.5% (30/171) of vaginal bloody discharge, 8.2% (14/171) of sacroiliac or buttock pain, 7. 6% (13/171) of skin blister,4. 7% (8/171) of leg pain, 2. 9% (5/171) of hematuria and 1.8% (3/171) of febrile. By logistic regression analysis, the factor correlated with abdominal pain included diameter of uterine leiomyomas,sonication time and average power (P < 0. 05). The factor correlated with sacroiliac or buttock pain was uterine leiomyomas located in posteriors of uterine wall(P <0. 05); the factors correlated with vaginal bloody discharge were sonication time and type of uterine leiomyomas (submucous > intramural > subserous, P <0. 05); the factors correlated with skin blister was sonication time (P < 0. 05). There were no statistical relationship between multiple factors and leg pain, hematuria, febrile (P > 0. 05). Conclusion The modality of high-power and short-term treatment might reduce complications of HIFU ablation.

Objective To observe the therapeutic effect of traditional Chinese medicine(TCM)granules made by the formula of Shegan Mahuang decoction for treatment of patients with asthma. Methods A prospective study was conducted,51 cases of light to moderate asthma(cold type)patients were randomly divided into treatment group (25 cases)and control group(26 cases). Conventional symptomatic treatments were of the same in two groups. The patients in control group were given salbutamol aerosol inhalation,100μg each time,4 times per day;based on the treatment of the control group,additionally the above mentioned TCM granules dissolved in water was administered orally 1 dose/day taken twice once in the morning and another once in the evening in treatment group. The therapeutic course was 12 weeks in both groups. Before and after treatment,the asthma control test(ACT)score,forced expiratory volume in 1 second(FEV1)and peak expiratory flow(PEF)were observed. The therapeutic effect,adverse reaction and compliance were evaluated. Results The number of patients with asthma completely controlled in the treatment group was significantly higher than that in the control group(16 cases vs. 9 cases,χ2=4.82,P=0.028). In the patients of two groups,FEV1,PEF and ACT scores were significantly improved after treatment,and in the treatment group,they were obviously higher than those in control group〔FEV1(L):2.67±0.46 vs. 2.32±0.47,PEF(L/min):327.6±49.4 vs. 273.1±42.8,ACT score:22.8±2.0 vs. 21.1±2.6,all P<0.05〕. After treatment,FEV1%predicted value was increased in the treatment group but decreased in control group,there was significantly statistical difference〔(0.68±0.07)% vs.(0.80±0.11)%,P<0.05〕,no significant adverse reaction was found,compliance was good. Conclusion TCM granules made by formula of Shegan Mahuang decoction can improve the clinical symptoms, pulmonary function and control level in patients with asthma,so it is an effective medicine for the control of asthma.

Background::Evidence indicates that low muscle strength is associated with an increased cardiovascular diseases (CVDs) risk. However, the association between muscle strength changes based on repeated measurements and CVD incidence remains unclear.Methods::The study used data from the China Health and Retirement Longitudinal Study in 2011 (Wave 1), 2013 (Wave 2), 2015 (Wave 3), and 2018 (Wave 4). Low muscle strength was defined as handgrip strength <28 kg for men or <18 kg for women, or chair-rising time ≥12 s. Based on changes in muscle strength from Waves 1 to 2, participants were categorized into four groups of Normal-Normal, Low-Normal, Normal-Low, and Low-Low. CVD events, including heart disease and stroke, were recorded using a self-reported questionnaire during Waves 3 and 4 visits. Cox proportional hazards models were used to investigate the association between muscle strength changes and CVD incidence after multivariable adjustments. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated with the Normal-Normal group as the reference.Results::A total of 1164 CVD cases were identified among 6608 participants. Compared to participants with sustained normal muscle strength, the CVD risks increased progressively across groups of the Low-Normal (HR = 1.20, 95% CI: 1.01-1.43), the Normal-Low (HR = 1.35, 95% CI: 1.14-1.60), and the Low-Low (HR = 1.76, 95% CI: 1.49-2.07). Similar patterns were observed for the significant associations between muscle strength status and the incidence risks of heart disease and stroke. Subgroup analyses showed that the significant associations between CVD and muscle strength changes were consistent across age, sex, and body mass index (BMI) categories.Conclusions::The study found that muscle strength changes were associated with CVD risk. This suggests that continuous tracking of muscle status may be helpful in screening cardiovascular risk.

Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. It is characterized by rapid progression, high mortality, and frequent sequelae. Early diagnosis and timely treatment can improve patient survival and long-term prognosis. Biomarkers such as procalcitonin (PCT), C-reactive protein (CRP), and interleukin-6 (IL-6) have been widely used in the early diagnosis of sepsis, but there still exist limitations on their specificity and sensitivity. Microfluidic technology was applied for the detection of some biomarkers and pathogenic microorganisms, not only because it has a higher specificity and sensitivity for the early diagnosis of sepsis, but also has a certain evaluation value for the severity of sepsis and the prognosis of patients. These quick and accurate methods have the feasibility of clinical application. To demonstrate the value of microfluidic technology for early diagnosis of sepsis and to guide the improvement of future research, the application of microfluidic technology in the diagnosis and treatment of sepsis was reviewed in this article.

Objective To investigate the safety and efficacy of ultrasound ablation in treatment of uterine fibroids. Methods Ninety-nine patients with 117 leiomyomas in total treated by Haifu JC focused ultrasound tumor therapeutic system were enrolled in prospective and non-randomized clinical trial in First Affiliated Hospital of Chongqing Medical University and Academy of Military Medical Sciences. Ultrasound ablation was performed guided by real-time ultrasonography under conscious sedation for single session. All patients were followed up at 6 months after treatment. On the day of treatment and after 1 month, patients were given by magnetic resonance imaging(MRI) exam to evaluate the effect of fibroids ablation. At 3 and 6months after treatment, the ratio of ablated area and volume reduction of fibroids more than 50% were evaluated by MRI exam again. The symptoms improvements were evaluated by uterine fibroid symptom (UFS) and complications were analyzed by guideline of society of international radiation (SIR). Results The average ablated area ratio of the target fibroid was (76 ± 24)%. The average reduction in fibroid volume determined by MRI at 3 and 6 months after treatment was (45 ± 21)% and (59 ± 26)%. Which were significantly decreased than those before treatment (P < 0. 05). At 6 months after treatment, 84. 6% (99/117) of patients showed more than 50% volume reduction, the rate of improved symptom score was 92%(66/72). All patients could resume normal daily activities at 2 hours after treatment. The adverse reactions of SIR C - D included delayed hospitalization, repeat treatment and increased level of nursing. E - F included permanent sequelae and death. In this study, no adverse reactions of C - F were recorded. Common complications (SIR A- B, only observation or simple management without sequelae) were 35% (35/99).Four cases with adverse reactions B of SIR were found, including 2 cases with skin burning of degree Ⅱ and 2 cases with febrile, they were administered by symptomatic therapy and changing dressing The other adverse reaction A of SIR included sorness of buttock, vaginal discharge, dysuria and painful urination, they were only suggested by follow-up. Conclusion It was efficacy and safe that ultrasound ablation as a single strategy were used in treatment of uterine fibroids.

Objective To explore the correlation between the replacing time of plasma drainage bag and the bacterial growth rate among orthopaedic surgery patients , and to control or reduce the risk of catheter-related infection.Methods The convenient sampling method was used to select 100 patients with postoperative serum drainage tube and disposable drainage bag , from September 2012 to August 2013.Patients were randomly divided into the control group (group A, 33 cases) and the observation group (group B, 32 cases; group C, 35 cases).The amount of drainage were recorded every 24 hours of the three groups of patients , and then the drainage bags were emptied .Group A replaced the drainage bag regularly every day; Group B replaced the drainage bag every 48 hours;Group C did not replace the drainage bag .The outside mouth of the drainage tube and the drainage liquid were taken to bacterial culture . The positive rate of bacterial culture , patients'postoperative body temperature and the rate of incision infection were compared within groups .Results Twenty-four hours after operation, the results of bacterial culture among three groups were negative .However, after 48 hours, six patients (18.1%) in group A, two patients (6.4%) in group B showed positive results of the bacterial culture .None of the patients in group C had the positive results .The comparison among three groups was statistically significant (χ2 =10.32,P<0.05).After 72 hours, eight patients (24.2%) in group A, two patients (6.4%) in group B showed positive results of the bacterial culture .None of the patients in group C had the positive results.The comparison among three groups was statistically significant (χ2 =11.82,P<0.05). The incidence of incision infection of group A , group B and group C were 15.1%(5/33), 6.3%(2/32) and 0.0%(0/35), respectively.There was a significant difference among three groups (χ2 =11.18,P<0.05).The body temperature of the three groups showed no significant difference (F=7.53,P>0.05).Conclusions With the increase of drainage bag replacement frequency , the positive rate of bacterial culture , as well as the drainage bag and drainage tube mouth bacteria culture positive rate increase .Therefore, for orthopaedic patients , the plasma drainage tube and disposable drainage bag should be emptied every 24 hours after the measurement of drainage liquid, but do not have to be replaced every 48 hours or every 24 hours.
