Objective To observe the clinical effects of estradiol valerate and drospirenone applying in missed abortion and curettage before and after operation.Methods 160 patients with missed abortion parallel curet-tage were chosen,who were randomly divided into the observation group and control group by the number table meth-od.Two groups of patients were oral misoprostol 400 g before uterine curettage 1 h,and then were treated with ultra-sonic curettage after filling the bladder and postoperative routine use of antibiotics for 3 D.3 D before the curettage, observation group were treated with oral estradiol valerate 4 mg for 3 D,2times a day..After curettage of the day, drospirenone orally was given for 1 tablet every night,used in conjunction a cycle for 3weeks.The control group before and after curettage were given without estradiol valerate and drospirenone.Operation time,bleeding volume,postopera-tive bleeding time and bleeding volume,the time of the first menstrual cycle,endometrial repair and postoperative complications were observed in the two groups.Results In the control group,operation time,intraoperative bleeding volume,for the first time the resumption of menstruation tide time,endometrial thickness,postoperative complication rate were (6.05 ±0.49)min,(50.88 ±9.18)mL,(36.51 ±1.95)d,(4.08 ±0.56)mm and 15.0%;the data of the observation group were (4.46 ±0.45)min,(35.63 ±8.24)mL,of (29.28 ±1.57)d,(6.11 ±0.76)mm and 3.8%.The operation time,intraoperative bleeding volume,for the first time the resumption of menstruation tide time, endometrial thickness,postoperative complication rate differences of the two groups were statistically significant(t =-11.264,-16.643,-24.93,19.151,χ2 =5.959,all P <0.05).Conclusion Giving estradiol valerate and flexor buspirone before and after missed abortion and curettage,can effectively improve the short -term and long -term complications of uterine curettage,and improve the clinical efficacy of dilatation and curettage.

Objective To analyze the incidence and related risk factors of chronic obstructive pulmonary disease (COPD) patients with deep venous thrombosis (DVT) in the respiratory intensive care unit (RICU).Methods We recruited 204 patients from RICU of our hospital between January 2015 and December 2015.The basic clinical data of the patients were also collected.Bedside venous ultrasonography of double lower limbs was taken 24-48 hours after admission.The patients were divided into DVT group and non-DVT group.The clinical data of the two groups were analyzed and compared using Chi-square test or t test,Logistic regression analysis was used to analyze risk factors,and ROC curve analysis was used to identify the disease.Results Among the 204 patients,39 were identified with DVT,with the overall incidence rate of 19.1％.D-dimer in DVT group was significantly higher than that in non-DVT group (P＜0.001).The two groups did not significantly differ in age,sex,smoking history,underlying diseases,or other laboratory test results.The area under the ROC curve of D-dimer was 0.787,and the cut off value was 1.985 mg/L (sensitivity of 0.641,specificity of 0.817).Conclusion D-dimer is closely associated with increased incidence of DVT in COPD patients.

Objective To observe the effect of pre-intervention with electroacupuncture on oxidative stress (OS) and inflammatory reaction after hepatectomy under portal occlusion.Method Thirty patients going to receive hepatectomy under Pringle's portal occlusion were randomized into an electroacupuncture group and a sham electroacupuncture group, 15 cases each. Three days prior to the surgery, the patients started to receive corresponding acupuncture or sham electroacupuncture treatment by selecting bilateral Riyue (GB24), Qichong (ST30) and Yanglingquan (GB34), once a day. The anesthesia method was general (inhalational and intravenous) anesthesia. Central venous blood was drawn before the surgery, and respectively 6 h, 24 h, 48 h and 72 h after the surgery to examine the OS-relatedparameters, superoxide dismutase (SOD) and malondialdehyde (MDA), as well as the inflammatory mediators, including tumor necrosis factor-α(TNF-α), interleukin (IL)-1, IL-6, and IL-10.Result Compared to the sham electroacupuncture group, the SOD activity significantly increased (241±11.4 U/mL,180±12.6 U/mL,P<0.05) and the MDA level significantly dropped in the electroacupuncture group at 6 h and 24 h after the surgery(11.0±0.8 mmol/L,10.0±0.9 mmol/L,P<0.05); there were no significant between-group differences in the rest indexes (P>0.05).Conclusion Pre-intervention with electroacupuncture can up-regulate the activity of SOD and down-regulate the level of MDA in patients after hepatic portal occlusion, and thus partially reduce OS, but it doesn't shownoticeable effecton inflammatory response.

Objective To analyze the relationship between serum 25 hydroxy vitamin D (25OHD) levels and semen pa?rameters. Methods The serum levels of 25OHD were examined in 68 healthy men, who were divided into three groups. Twenty-two cases were included in 25OHD normal group (30μg/L≤25OHD<40μg/L), 20 cases were in 25OHD relatively insufficient group (20μg/L≤25OHD<30μg/L), and 26 cases were in 25OHD deficiency group (25OHD<20μg/L). The se?rum reproductive hormones including follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E 2), prolactin (PRL) and testosterone (T) were detected by chemiluminescence immune analysis. Semen samples were collected by mastur?bation after a period of abstinence for 3 and 7 days. The total sperm count, sperm concentration, percentage of progressive motile sperm and percentage of normal morphology sperm were measured by sperm quality analyzer. Results There were no significant differences in FSH, LH, E2, PRL and T levels between three groups, and which were all in normal ranges. The total sperm count, sperm concentration, percentage of progressive motile sperm and percentage of normal morphology sperm were significantly lower in 25OHD relatively insufficient group and 25OHD deficiency group than those in 25OHD normal group. The total sperm count and the percentage of progressive motile sperm were significantly lower in 25OHD deficiency group than those in 25OHD relatively insufficient group (P<0.05). There were no statistical differences in sperm concentra?tion and percentage of normal morphology sperm between 25OHD deficiency group and 25OHD relatively insufficient group. Conclusion The decrease of semen quality may be related to serum 25OHD at the relatively insufficient and deficiency lev?els. The effect of 25OHD on semen parameters may not be mediated by reproductive hormones.

Objective To analyze the dermal irritation characteristics of 8 types of cosmetics.Methods The selected 917 cosmetics samples of 8 types,which were underwent the health safety test in China during 2005-2007,were assessed in the acute dermal irritation according to the related standards and the data were statistically analyzed using CMH method.Results The dermal-irritant samples were detected in different levels in 8 types of cosmetics.In terms of the irritation of cosmetics and the dermal damage caused by cosmetics,the cosmetics for hair,for face clean and for bath showed a significant higher proportion compared with the other types of cosmetics and the dermal damage could last for more than 14 days.Conclusion The acute dermal-irritability is different in 8 types of cosmetics,the cosmetics for hair,for face clean and for bath can cause the irritation and damage in the skin in degrees.

Objective To find the normal range and features for auditory brainstem responses(ABR)of infants within six months,and the basic parameters for identifying the hearing impaired infants.Methods May 2006 to May 2008,60 normal infants and 20 normal adults received the ABR tests.The infants were divided into three groups:group A(6 weeks),group B(3 months)and group C(6 months).Each group consisted of 20 infants(40 ears)and the ABR data were statistically analyzed.Results At 100 dB nHL,the waveⅠ,Ⅲ,Ⅴ latencies of ABR for 6-week infants respectively were 1.49?0.08 ms,4.42?0.16 ms and 6.61?0.25 ms,for 3-month infants,1.47?0.07 ms,4.35?0.20 ms and 6.50?0.25 ms,for 6-month infants,1.45?0.07 ms,4.17?0.15 ms and 6.32?0.22 ms.At 80 dB nHL,the waveⅠ,Ⅲ,Ⅴ latencies of ABR for 6-week infants were 1.63?0.08 ms,4.52?0.17 ms and 6.74?0.26 ms,respectively,for 3-month infants,1.64?0.11 ms,4.44?0.20 ms and 6.67?0.26 ms,for 6-month infants,1.60?0.11 ms,4.27?0.16 ms and 6.43?0.24 ms.As the intensity of stimulating signals decreased,the peak latency of ABR became more delayed.The peak latencies of Ⅲ,Ⅴ waves and interval peak latencies of Ⅰ-Ⅲ and-Ⅴ waves for the infants were more delayed than those for adults,and became shorter with the increase of the infants' ages,but they failed to reach adults' levels even for 6-month infants.However,the length of wave Ⅰ of ABR for infants of different months was close to that for adults.The thresholds of ABR for the infants of different ages were not significantly different,all being close to the values for adults.Conclusion This study has analyzed the ABR wave features for the infants of three ages and this can help to define the reference ranges for the infants and to provide the parameters for early diagnosis of hearing loss among the infants.

Objective To investigate the effects of repetitive transcranial magnetic acupoint stimulation on hemiplegic patients.Methods60 hemiplegic patients were assigned to treatment group and control group(30 cases for each group). Both groups received rehabilitation therapy. Meanwhile, the treatment group received repetitive transcranial magnetic acupoint stimulation. Fugl-Meyer Assessment (FMA), The Mini-Mental State Examination (MMSE), Barthel Index(BI) were used to measure the outcome.ResultsThe scores of FMA and BI increased significantly in both groups after treatment. However, these scores in treatment group improved more compared with those of control group(P<0.05).ConclusionRepetitive transcranial magnetic acupoint stimulation is helpful to improve the motor function, and ability of daily living of hemiplegic patients.

● AIM: To explore the role that hepatocyte growth factor plays in proliferative vitreoretinopathy (PVR) after retinal detachment.● METHODS: The contents of hepatocyte growth factor in subretinal fluid (SRF) in 49 cases with retinal detachment were measured with enzyme-linked immunosorbent assay.● RESULTS: With the worsening of PVR and vitreous opacity and prolonging of disease course, the content of hepatocyte growth factor increased (P＜0.05), the difference being statistically significant.● CONCLUSION: The change of hepatocyte growth factor in SRF had a close relation ship with the occurrence and development of PVR after retinal detachment.

Objective To evaluate the preoperative nutritional status of patients with colorectal carcinoma by using the nutritional risk screening 2002 (NRS2002) score and its prediction for postoperative outcomes.Methods Retrospectively evaluated the nutritional risk of 259 colorectal cancer patients with NRS2002 score in terms of different sexes,ages,tumor location,pathology and differentiation,Dukes stages.The relationship between different NRS2002 score and postoperative complications and hospital stay were also observed.Results NRS2002 score was applicable in 243 cases,≥ 3 scores of 80 cases,＜ 3 scores of 163 cases.Gender,histological differentiation and before surgery NRS2002 score unrelated (P ＞ 0.05).Ages,tumor location,and Dukes stages related NRS2002 score (P ＜ 0.01).No case of perioperative death,hospital stay 10-101 (21.6 ± 9.7) d.The incidence of complications in ≥ 3 scores patients was significantly higher than that in ＜ 3 scores patients [30.0％ (24/80) vs.17.2 ％ (28/163),P ＜ 0.05],hospital stay in ≥ 3 scores patients was significantly shorter than that in ＜ 3 scores patients[(20.5 ± 8.2) d vs.(23.9 ± 11.9) d,P＜ 0.05].Multiple Logistic regression analysis showed that gender,age,tumor location,histological differentiation,Dukes stages,surgical and colorectal cancer complications unrelated (P ＞ 0.05),NRS2002 score associated with colorectal cancer complications (P ＜ 0.05).Pearson correlation analysis showed that hospital stay correlated with NRS2002 score (P ＜ 0.01).Conclusions NRS2002 score is applicable in Chinese colorectal cancer patients.The youth and the elderly,the proximal part of colon,and Dukes D stage patients are more liable to develop preoperative nutritional risk than those of middle age,the distal part of colon,or other Dukes stages.≥ 3 scores predicts higher postoperative complications and longer hospital stay.Preoperative nutritional support is necessary in patients with ≥ 3 scores.

Objective To study the effect of shortening the time of initial oral intake and fluid intake after general anesthesia in patients receiving oral and maxillofacial surgery on promotion of postoperative recovery. Methods A total of 116 patients were divided into the control group and the observation group with 58 cases in each group by random digit table from January 2014 to December 2015. Patients in the control group were allowed to take food orally 6 h after they regain analepsia from anesthesia;while those in the observation group were allowed to drink water after 2 h upon analepsia from anesthesia and take liquid food after 4 h. The mis-aspiration, the fasting glucose, blood pressure, heart rate and the rate of hunger, thirst, nausea, vomiting as well as blood pressure and heart rate were observed. Results The rates of hunger, thirst, nausea, vomiting in the observation group were 17.2%(10/58), 5.2%(3/58), 12.1%(7/58), 1.7%(1/58), which were significantly lower than those in the control group, which were 94.8%(55/58), 91.4%(53/58), 36.2%(21/58), 10.3%(6/58), and there were significant differences(χ2=7.484-54.772, all P<0.05). The fasting plasma glucose level in the observation group [(4.93 ± 0.85)mmol/L] was higher than that in the control group [(4.05 ± 0.51)mmol/L],and there was significant difference(t=-7.152, P<0.05). There were significant differences in blood pressure 3 h and 5 h after operation compared with those of the control group(P<0.05). Conclusions Shortening the time of taking food for patients undergoing oral and maxillofacial surgery can relieve uncomfortable symptoms , prevent hypoglycemia and the hemodynamic disturbance after anesthesia and promote recovery,early postoperative feeding should be suggested on the premise that they are fully awake.
