Objective To understand the indoor air pollution caused by smoking and the influencing factors.Methods On the different time after and before smoking,the concentrations of carbon monoxide(CO),inhalabe particle(IP),formaldehyde,total volatile organic compounds(TVOC) in the air in an office were determined,the influence factors such as ventilated conditions and the number of smokers were investigated.Results When the windows and doors were closed,the concentrations of indoor air pollutants at the different time after smoking in the office were obviously higher than those without smoking,and formaldehyde and TVOC still exceeded the standard limit after 3 hours.When the windows and doors were opened,the concentrations of indoor air pollutants after smoking increased obviously,but decreased to the level of no smoking about 30 minutes later.When the windows and doors were opened,the peak values of the indoor air pollutants resulted by smoking were obviously lower than those when the windows and doors were closed.The peak values of the pollutants were positively related to the number of smokers. Conclusion Indoor air pollution caused by smoking is serious.Ventilation can reduce the indoor air pollution effectively.

Objective To investigate the clinical effect of the 1 470 nm diode laser for the treatment of superficial bladder tumor.Methods Two hundreds and sixteen patients diagnosed with superficial bladder tumor were treated in our hospital from January 2012 to January 2014 and divided into the laser group and electric cutting group.The two groups were treated by 1 470 nm diode laser and transurethral plasma kinetic resection respectively.The basic data and the observation indexes were compared be tween the two groups.Results The operation time,intraoperative bleeding volume,indwelling catheter time and hospital stay time in the laser group were significantly less than those in the electric cutting group.The levels of epinephrine,norepinephrine and an giotensin Ⅱ in operation and at postoperative 6 h in the laser group were significantly lower than those in the electric cutting group (P＜0.05).The obturator nerve reflex and bladder perforation did not occur in the laser group,and the total complications occurrence rate was 5.1％,the bladder tumor recurrence rate in postoperative 24 months was 7.1％.The obturator nerve reflex occurrence rate was 7.6％,the vesical perforation rate was 1.7％,the total complications occurrence rate was 15.3％,the bladder tumor recurrence rate in postoperative 24 months was 17.8 ％ in the electric cutting group.The above indexes of the laser group were significantly lower than those of the electric cut group(P＜0.05).Conclusion The 1 470 nm diode laser for the treatment of noninvasive superficial bladder tumor has definitely curative effect,is easy to operate with low postoperative complication occurrence rate,high safety and low middle and long term recurrence rate,moreover has little influence on patient's stress level.

Objective To investigate the clinical efficacy of laparoscopic hepatectomy.Methods The clinical data of 258 patients who received laparoscopic hepatectomy at the First Affiliated Hospital of Fujian Medical University from March 2010 to January 2013 were retrospectively analyzed.There were 196 patients with primary hepatic cancer,45 with hepatic hemangioma,13 with hepatic focal nodular hyperplasia,2 with hepatic metastatic cancer,1 with carcinoma of gallbladder and 1 with hepatic hamartoma.All patients were followed up via phone call or out-patient examination till March 2013.Results A total of 142 patients received single hepatic segmentectomy,98 received multiple hepatic segmentectomy,18 received multiple lesions resection.Fifty-one patients received hepatic tumorectomy + cholecystectomy.All the operations were successfully done under laparoscope without conversion to the open surgery.The mean tumor diameter and the operation time were (5 ± 3) cm (range,1.0-11.5 cm) and (113 ± 56) minutes (range,50-310 minutes),respectively.Intraoperative hepatic portal occlusion was performed on 122 patients,and the time for hepatic portal occlusion was (15 ± 7)minutes.The volume of intraoperative blood loss was (211 ± 195)mL (range,10-650 mL),and blood transfusion was not needed.The capsule of the tumor was complete.The distance between the resection margin and the malignant tumor was above 1.5 cm,and there was no residual tumor in the resection margin.The hepatic function was back to the normal level in 1 week after the operation,and no patient had hepatic failure.The duration of postoperative hospital stay was (7.2 ± 1.3)days (range,5-10 days).One patient was complicated with bile leakage,6 with slight peritoneal effusion,and other patients had no postoperative complications.The rate of follow-up was 91.47％ (236/258),and the time of follow-up was (16 ± 10) months.A total of 199 patients with malignant hepatic tumors were followed up.During the follow-up,180 patients had tumor-free survival; 18 patients had postoperative tumor recurrence; 1 patient had omental metastasis and received surgical resection.Thirty-seven patients with benign hepatic tumor survived without complication during the follow-up.Conclusion Laparoscopic hepatectomy is effective for the treatment of hepatic tumors.Multiple hepatic inflow occlusion under laparoscope in a short time may improve the safety of surgery,without prolonging the recovery time of patients.

Objective To examine the impact of cognitive behavior intervention (CBI) on mother-infant interaction in the neonatal department. Methods Low-risk appropriate for gestational age premature infants with gestational age 28-36 weeks, who were admitted to the neonatal intensive care unit in our hospital between August 2007 and May 2008, and their mothers were assigned to intervention group and control group respectively. Intervention group mothers (n = 19)participated in CBI. Control group mothers (n= 19) were asked to read educational materials. Mothers in the intervention group, all received 4 times interventions and 2 h for each time. The CBI process include assessment, plan, implementation and evaluation. Mothers were educated for knowledge about appearance and behavioral characteristics of preterm infants and were guided about how to take care of their babies and participate in nursing care process. Mothers completed measures on mother-infant interaction (Nursing Child Assessment Feeding Scale, NCAFS) in the first follow-up after infant discharge. Results The results showed that the scores of NCAFS and total scores of the mothers in the intervention mother-infant dyads were 46.4 ± 8.5 and 35.8±6.3,higher than in the control group (42.7±5.9 and 33.3 ± 5.6), respectively, but there were no statistic difference between the two groups (t = 1.55 and 1.28, P＞ 0. 05). The scores of "mother's response to distress" were significantly higher in the intervention mother-infant group (12. 2± 1.7) than in the control group (10.7±2.4)(t=2.10,P＜0.05). Conclusions The levels of premature infant-mother interactions are low. CBI can improve mother's response to premature infant's distress. Further study is needed to investigate the effects of CBI in improving mother-infant interaction.

Objective To investigate the clinical effect of using uninterrupted vacuum sealing drainage combined with routine debridement and pedicled periosteal flap sealing frontal sinusitis in treating frontal sinusitis after craniotomy.Methods The clinical data in 31 cases of frontal sinusitis after craniotomy in our hospital from January 2006 to December 2014 were retrospectively analyzed.Seventeen cases adopted simple debridement and drainage treatment and 14 cases were treated with continuous vacuum sealing drainage combined with routine debridement treatment.Postoperative follow up lasted over 1 year.Results In simple debridement and drainage,12 cases were cured,the other 5 cases recurred after operation,and the cure rate was 70.6 ％.But in the continuous vacuum sealing drainage combined with routine debridement treatment,14 cases were cured,no case recurred after operation,and the cure rate was 100％.Therefore,the cure rate of continuous vacuum sealing drainage treatment combined with routine debridement was higher than that of simple debridement and drainage treatment(P＜0.05).Conclusion Adopting vacuum sealing drainage combined with routine debridement and pedicled periosteal flap sealing frontal sinusitis can promote the infection focus clearance and wound healing,and increases the cure rate.

Objective To retrospectively review the epidemiological data from 159,242 patients hospitalized after traumatic brain injury in traffic accidents and provide epidemiological evidences for the prevention and treatmentmeasures.Methods Patient data were collected using the Chinese Trauma Database for the years 2001-2007.Epidemiological features of age,gender,time distribution,length of hospital stay,state of injury,and treatment outcome were recorded.Results Age of the patients was (33.01 ± 15.20) years and ratio of male to female patients was 2.39∶ 1.The majority were aged 21-50 years with the 31-40 age group were more vulnerable.Annual average growth of age was 3.92％.Within a year,number of the patients accounted for 54.10％ from July to December with it reached the peak in October.Mean length of stay was 20.20 days with the longest stay in the ≥90 age group and shortest stay in the ≤10 age group.Mean hospital charges was 13 689.8 yuan with the ≤10 age group occupying the least and 51-60 age group occupying the most.Overall cure rate was 66.92％ and mortality was 4.22％.Proportion of severe traumatic brain injury in traffic accidents increased and related cure rate decreased with increased age.Male patients showed higher death rate and lower cure rate compared with female patients.Conclusions Incidence of traffic accidents-related traumatic brain injury is the most in the young and middle-aged population and is prevalent in the second half year.There should be emphasis on the aged or male patients.Measures to prevent and treat the injury may produce better results when defined based upon these epidemiologic features.

Objective: To systematically evaluate the clinical effect of Xiaoke Decoction in the treatment of type 2 diabetes. Methods: Chinese databases such as CNKI, Wanfang, Weipu Chinese Biomedical Journal Database, and Chinese Medical Biological Literature Database, PubMed, Cochrane Library, Embase, and Web of Science were searched for English language literature from their inception until November 2019. A Meta-analysis was performed using RevMan 5.3 and Stata 12.0. Results: Thirty-eight studies were included in this study, with a total of 3757 patients. It was found that adding Xiaoke Decoction could improve total efficiency. The Xiaoke Decoction groups surpassed the western medicine groups regarding improvement in total efficiency (OR = 3.49; 95% CI: 2.78–4.39, P < 0.00001). Adding Xiaoke Decoction could lower the fasting plasma glucose (FPG) level. The Xiaoke Decoction groups surpassed the western medicine groups regarding reduction in FPG levels (MD = −1.14; 95% CI: −1.36 to 0.92, P < 0.00001). Adding Xiaoke Decoction could lower the 2 h postprandial blood glucose (2hPG) level. The Xiaoke Decoction groups surpassed the western medicine groups regarding reduction in 2hPG (MD = −1.40; 95% CI: −1.61 to 1.19, P < 0.00001). Adding Xiaoke Decoction could lower glycated hemoglobin (HbA1c). The Xiaoke Decoction groups surpassed the western medicine groups regarding reduction in HbA1c (MD = −0.77; 95% CI: −0.95 to 0.58, P < 0.00001). It was found that adding Xiaoke Decoction could lower the traditional Chinese medicine (TCM) syndrome score. The TCM syndrome scores among patients in the Xiaoke Decoction group were lower than those among patients in the control group after treatment (MD = −4.90; 95% CI: −7.22 to 2.57, P < 0.0001). At the same time, we conducted a subgroup and sensitivity analysis of age and intervention duration on the heterogeneity of total efficiency, FPG, 2hPG, HbAlc, and TCM syndrome score outcome indicators. For detecting publication bias, an egger test was conducted. Conclusion: Compared with western medicine alone, Xiaoke Decoction has more advantages for the treatment of type 2 diabetes with respect to total efficiency, FPG, 2hPG, HbAlc, and TCM syndrome score.
