Objective To explore the long-term health effects of overexpose to radiation.Methods The 32 -41-year medical followed-up observations were performed for 25 persons exposed to ionizing radiation in the dose range of 0.10 -0.33 Gy. Observations were made of clinical symptom,eye lens,cytogenetics,immune function and endocrine function for these persons. Results The incidence of neurasthenic symptom was higher in exposed group than that in control group.2 cases suffered from liver cancer and esophageal cancer,respectively. Posterior capsule punctate phacoscotasmus of the lens wereobserved in 7 cases.There was I case of cataract in the exposed group. The frequencies of chromosomeaberration and micronucleis in peripheral blood lymphocyte in the exposed group were significantly higherthan those in control group (x2 =8.88,8.71,40.60,45.63,P ＜ 0.05 ).The average value of serum IgG was higher(t =2.16,P ＜0.05 ),while that of IgM was obviously lower in the exposed group (t =2.03,P ＜0.05).The average values of serum triiodothyronine (T3),thyroxine (T4 ) and thyroid-stimulating hormone (TSH) in the exposed group were obviously lower than those in the control group (t =2.40,3.54,2.13,P ＜0.05 ).Conclusions Overexposure has effect on lens,immune function,cytogenetics to some degree.It is important to observe the long-term health effect on overexposed persons.

Objective To explore the effect and complication of diode laser and long-pulsed alexandrite laser for hair removal in different skin type.Methods A total of 1061 patients (1741 sites) were divided into 2 groups by skin type:one group were treated with diode laser,with wave length of 810 nm,and pulse width of 400 ms,with 12 mm × 10 mm spot size; another group were treated with long-pulsed alexandrite laser,with wave length of 755 nm,of pulse width of 20 ms,with 12.5 mm spot size,50-60 days intermitted between each treatment.Results The effect of hair removal by two lasers in different skin type was without divergence,but to darker skin,complication was lower when treated by diode laser.Conclusions The effect of hair removal by two lasers in different skin type is similar,but diode laser on hair removal is much safer to dark skin.

Objective To investigate the role of apoptosis-related gene survivin, caspase-3 and cyclin-B1 in gastric carcinoma by detecting the expressions of survivin, caspase-3 and cyclin-B1 in gastric carcinoma. Methods The expressions of survivin mRNA, caspase-3 mRNA and cyclin-B1 mRNA were determined by reverse transcription-polymerase chain reaction (RT-PCR) method in 30 gastric carcinoma specimens and 10 normal gastric tissue specimens. Results The positive expression rate of survivin mRNA in 30 gastric carcinoma specimens was 66.7%(20/30). While 10 normal gastric tissue specimens did not express survivin mRNA. Although all of 30 gastric carcinoma tissues and 10 normal gastric tissues expressed caspase-3 mRNA and cyclin-B1 mRNA, the expressions of caspase-3 and cyclin-B1 in 20 survivin-positive gastric carcinoma tissues were significantly lower than those of 10 survivin-negative gastric carcinoma tissues (P

Objective To observe late effect of 60Co radiation accident on eye lens in the victims.Methods Medical observations of eye lens were performed on ten victims accidentally exposed to 60Co sources in four radiation accidents that have occurred from 1986 to 2000 in Henan Province.Pathological changes of the eye lenses were examined by using slit lamp microscopy after mydriasis with compound tropicamide.Results Of these ten victims, Liang in a radiation accident in Kaifeng (in 1986), Mei in Xinxiang (in 1999) and Xu in Xuchang (in 2000) all had typical radiation-induced cataract 2, 3 and 6 years after irradiation, respectively.Follow-up observation of the lens showed the punctate and/or granular opacities present in the eye posterior subcapsular of Yan in Kaifeng accident, Jie in Zhengzhou (1987), and Tian, Yong and Yi in Xinxiang accident, featuring the early changes of radiation-induced cataract, but the posterior subcapsular opacities were not observed in Wang and Min in Xinxiang accident.Conclusions Focus should be on the eye lens as the target organ of radiation exposure in long-term follow-up of victims accidentally exposed to radiation source.Severity of the lens opacity induced by ionizing radiation is closely associated with radiation doses.

Objective To determine effect of endurance training on the expression of fatty acid translocase FAT/ CD36 in skeletal muscle of rats and the correlation between the expression and insulin sensitivity index (ISI). Methods Male Sprague-Dawley rats were randomly assigned to two groups:training group(T,n=13) and control group (C, n=10). Rats in group T were trained on treadmill six days a week for 7 weeks. Fat pads around testes and kidneys were weighted for calculating the percentage of fat pads vs body weight. Serum total cholesterol (TC), triglyceride (TG),nonesterified fatty acids(NEFA) and fasting insulin(FINS) were measured. Western blot was used to detect FAT/ CD36 protein expression in quadriceps homogenate. The relation of FAT/CD36 expression to the ISI was analyzed. Results Markedly lower body weight,percentage of fat pads, TC,NEFA, and FINS were seen in group T after 7-week endurance training comparing to that in group C(P<0.01 ,P<0.01 ,P<0.01 ,P<0.05,and P<0.05,respectively). The FAT/CD36 protein expression and ISI were significantly higher in group T than in group C(P<0.01and P<0.05). A significant correlation between FAT/CD36 and ISI were found in group T(r=0.823,P<0.01 ),nut not in group C. Conclusion Seven-week endurance training improved insulin sensitivity and up-regulated the expression of FAT/CD36 for adapting the requirement of fatty acid transportation in skeletal muscle induced by enhanced lipid catabolism after endurance exercise.

OBJECTIVE To observe therapeutic efficacy and safety of transcatheter arterial chemoembolization (TACE) com-bined with high intensity focused ultrasound (HIFU) in the treatment of middle and advanced primary hepatocellular carcinoma (HCC). METHODS:76 patients with middle and advanced primary HCC were randomly divided into treatment group(36 cases) and control group(40 cases). Control group was given TACE alone,and treatment group was additionally given HIFU 2-3 weeks after TACE. Clinical efficacy,the content of alpha-fetoprotein(AFP)before and after operation,survival rate,survival period and ADR were compared between 2 groups. RESULTS:The efficiency rate and total effective rate of treatment group were 61.1% and 94.4%,which were significantly higher than those of control group(35.0%,77.5%),with statistical significance(P<0.05). The content of AFP in 2 groups decreased significantly after operation,with statistical significance(P<0.05);there also was statistical significance between 2 groups(P<0.05). Survival rate of treatment group was higher than that of control group 24 and 36 months after operation,with statistical significance (P<0.05). The median survival time was 11.3 months in treatment group and 9.2 month in control group,with no statistical difference(P>0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Com-pared with TACE alone,TACE combined with HIFU in the treatment of middle and advanced primary HCC can improve long-term survival rate and the short-term efficacy,with good safety.

Objective To investigate newborn hearing screening status in Changyuan in order to explore how to improve the rate of newborn hearing screening. Methods Newborn babies born in Henan Honliv Hospital from October 2010 to December 2012 were included. TEOAE otoacoustic emission was used for the frist and the second screening. The babies who failed in the frist tests recieved the second screening after 42 days. The newborns who did not pass the second tests were referred to the children's Hospital of Zhengzhou hearing screening center for diagnosis and follow-up tele-phone. Results A total of 8 240 babies were born in our hospital from October 2010 to December 2012. Amomg these 8 240babies, 6 908 received the hearing screening with the rate of 83.83%(6 908/8 240),in whom 6 149 passed the frist screening with a rate of 89.01%(6 149/6 908), 759 failed. 402 out of 759 finished the second screening with a rate of 52.96%(402/759), in whom 350 passed the screening with a rate of 87.06%(350/402),52 failed. 40 out of 52 finished the hearing evaluation and medical diagnosis. At last, 8 subjects was confirmed hearing loss,in whom 3 sub-jects were full-term newborns,5 subjects of high risk infants.(3 subjects of prematureinfants,2 subjects of hyperbiliru-binemia). The detection rate of congenital hearing loss was 1.16‰(8/6 908). Conclusion The detection rate of congen-ital hearing loss in Henan Honliv Hospital from October 2010 to December 2012 was 1.16‰. The tates of newborn hearing screening an rescreening in Changyuan are low, High risk infant occured in congenital hearing loss was signifi-cantly higher than that of full-term infant.

OBJECTIVETo explore the feasibility and safety of transanal minimal invasive or combined laparoscopy total mesorectal excision.

METHODSClinical data of 11 cases with rectal cancer undergoing transanal total mesorectal excision(taTME) in our hospital between September 2014 and May 2015 were analyzed retrospectively.

RESULTSAmong 11 patients, 3 underwent pure-taTME successfully without abdominal incision and ileostomy, whose operation time was 210, 230, 215 min respectively, while other 8 patients underwent laparoscopy-assisted taTME(hybrid-taTME) with operation time ranging from 150 to 290 (median 205) min. No patient was transferred to open operation, while larger tumors of two patients were removed from hypogastric 5 cm incision. Postoperative first day VAS score was 1 to 3(2.0±0.6), the first flatus was 6 to 70(30.2±17.3) h, hospital stay was 4 to 12(7.5±2.5) d, the blood loss was (104±127) ml and the liquid food intake was (28.3±6.3) h. Postoperative complications included 1 case of subcutaneous emphysema, 1 case of anastomotic stoma bleeding, 2 cases of dysuria, which were cured by conservative therapy. One patient developed rectovaginal fistula 20 days after operation and then underwent ileostomy. No relapse of tumor or death during follow-up.

CONCLUSIONSFor suitable rectal cancer patients, taTME or hybrid-taTME is feasible.
