ObjectiveTo explore the influence of different hemostatic measures of laparoscopic ovarian cyst removed on ovarian function.MethodsSeventy patients with ovarian cyst who performed laparoscopic ovarian cysts removed between January 2009 and December 2010 were randomly divided into group Ⅰ (23 cases) and group Ⅱ (47 cases) by mechanical sampling.Group Ⅰ with bleeding electrocautery,group Ⅱ with suture.Estradiol,follicle puncture hormone (FSH),luteinizing hormone (LH),number of sinusoidal follicles,normal ovarian function and the number of declining ovarian reserve were compared in two groups before operation and after 6 months operation.ResultsAfter operation,the proportion of group Ⅱ with normal ovarian function was significantly higher than that of group Ⅰ[80.9％(38/47) vs.39.1％(9/23),P ＜ 0.05 ],estradiol and number of sinusoidal follicles were significantly higher than those of group Ⅰ [( 198.4 ± 24.4) pmol/L vs.( 153.4 ± 16.8) pmol/L,7.1 ± 2.4 vs.5.8 ± 0.9](P＜ 0.05),FSH and FSH/LH were significantly lower than those of group Ⅰ[ ( 10.58 ± 4.57) U/L vs. ( 13.72 ± 2.58) U/L,2.34 ± 1.32 vs.2.82 ± 0.88 ] (P ＜ 0.05).ConclusionDuring laparoscopic ovarian cyst removed,using electrocautery can significantly reduce residual ovarian function,but using suture hemostasis can effectively protect residualovarian function.

Post-ERCP pancreatitis(PEP) is the most common and serious complications about endoscopic retrograde cholangiopancreatography(ERCP).A number of studies have been confirmed that PEP can be prevented by pancreatic stents.We summarized earlier results in this field to expand the clinical use for this high-tech.

The Polarographic and voltammetric behavior of Cd (Ⅱ)-meso-tetrakis(p-sulfophenyl)prophyrin (TPPS4） complex was defined and the cyclic voltammetric peak was obtained at 1.200 V (vs. SCE) in 0.3 mol/L NaoH solution. The characteristics of the peak have been examined in detail and the experimental results prove that the peak has adsorption properties. In addition to the number of electrons transferred in the reaction and the complex ratio, the stability const ant (β=1.19×107) was calculated. The peak current was proportional to the concentration of Cd (Ⅱ) over the rang 3×10－7～1×10－5 mol/L and the limit of detection was 6×10－8 mol/L. Furthermore a possible mechanism was proposed for the reduction of the complex.

Objective By contrasting and analyzing the clinic manifestations, radiological features and pathological results of patients with bone invasion from skin of the lower limbs that were associated with malignancy, authors advanced X-ray diagnostic evidence to promote its diagnostic accuracy. Methods The radiological appearances of squamous cell carcinoma arising in chronic ulcers, sinus and scars of the lower limbs in 16 patients from February 1968 to April 2002 confirmed by pathology, were analyzed retrospectively. All cases were taken posterior-anterior and lateral radiograph before operation. There were 15 males and 1 females aging from 15 to 67 years (mean, 50.4 years). The lesion was located at the front of tibia in 15, and the middle inferior part of femur. The medical history of primary diseases varied from 1 to over 50 years with an average of 20 years and 3 months. Of 16 cases, the duration of 8 cases from a sudden change of state of an illness to the final diagnosis was 4 to 6 months, 4 cases above 1 year, and 4 cases were found with no any change of state of an illness. Results There were 14 cases observed as typical chronic osteomyelitis, which demonstrated peripheral osteolytic defect, 13 cases with osteolytic destruction spreading outwards from front of tibia, and 1 case with widespread osteolytic destruction in the middle and inferior part of femur. Floating-ice-like rudimental bone in the defect was found in 11 cases, and 4 case were observed with old fracture. 2 cases without obvious history of typical chronic osteomyelitis, 1 case with soft tissue trauma and 1 case of burn, showed small Saucer-like erosion of the cortex and huge lobar soft tissue masses. Moreover, patchy shadow and Codman's triangle were found in 1 case of burn. Furthermore, lobar soft tissue masses and huge ulcer accord with osteolytic destruction was observed in all cases, and soft tissue masses were larger than the area of bony destruction in 6 cases. Conclusion Roentgenogram could display shape, location and extension of bone invasion from skin of the lower limbs that were associated with malignancy, which contribute to diagnose the lesion and provide useful evidence for surgical plan.

OBJECTIVE To explore the risk factors and protective measures on ICU attendants.METHODS According to the risk factors of ICU occupational exposure,we developed and standardized the implementation of the protective measures.RESULTS The occupational exposure protection awareness,prevention methods,and self-protection were improved.CONCLUSIONS The education about occupational of exposure can improve the management of occupational safety and ensure the protection of physical and mental health of attendants,and to prevent the occurrence of hospital infection.

Objective To observe the clinical characteristics in the patients with post infectious irritable bowel syndrome(PI-IBS) and patients with non-PI-IBS(NPI-IBS).Methods Ninety-three patients with irritable bowel syndrome(IBS) treated in our hospital from March 2014 to June 2015 were selected,including 38 cases of PI-IBS and 55 cases of NPI-IBS.The differences of serum inflammatory cytokines levels,gastrointestinal score and gastrointestinal function were compared between the two groups.Resuits The levels of CRP,IL-18 and IL-6 in the PI-IBS group were significantly higher than those in the NPI-IBS group,and the difference was statistically significant (P＜0.05);the level of GAS,VIP and MOT in the PI-IBS group were significantly lower than those in the NPI-IBS group,the difference was statistically significant(P＜0.05);the bowel sounds score,abdominal distension and pain score and gastrointestinal reaction score in the PI-IBS group were obviously higher than those in the NPI-IBS group,the difference was statistical significance (P＜0.05);the various dimensional scores of quality of life in the PI-IBS group were lower than those in the NPI-IBS group,and the difference was statistically significant (P＜0.05).Conclusion The levels of serum inflammatory cytokines in PI-IBS patients are higher,moreover the gastrointestinal function is poorer than that in NPI-IBS patients,which can be the indicators of clinical differentiation.

Objective To investigate the prevalence and clinical characteristics of thyroid dysfunction induced by IFNα therapy in patients with chronic hepatitis.Methods Thyroid function of 310 patients with chronic hepatitis receiving IFNα therapy were evaluated.Results Serum free tri-iodothymnine (F13),free thyroxine(FT4)and sensitive thyroid-stimulating hormone(sTSH)of all patients were normal and TGAb was negative before IFNα therapy.After the treatment,10 patients(10/3 10,3.22%)had thyroid dysfunction,in which 7 were of hypothyroidism and 3 were of hyperthyroidism.The thyroid function of all patients recovered within 1-year follow-up.Conclusions IFNα therapy may induce thyroid dysfunction in patients with chronic hepatitis,in which prognosis can be good when appropriate treatment is given.

Objective To explore the efficacy of circular wound edge protector(CWEP)in preventing surgical site infection (SSI)following open abdominal surgery,analyze the related risk factors for postoperative SSI,and provide scientific basis for preventing SSI following open abdominal surgery.Methods 162 patients who underwent open abdominal surgery in a hospital from March 2014 to December 2015 were randomly divided into intervention group (used CWEP during surgery)and control group (used sterile gauze pad to protect incision).Length of hospital stay,cost of dressing change,and SSI between two groups were compared,risk factors for postoperative SSI were analyzed.Results Incidence of SSI in intervention group was lower than control group (14.81%[12/81]vs 34.57%[28/81],P <0.05);grade-A incision healing rate of intervention group was higher than control group(86.42% vs 66.67%,P <0.05).The cost of dressing change in intervention group was lower than control group([305.5 ± 176.7]yuan vs [431.6 ± 381.4 ]yuan,P = 0.008 ). Multivariate logistic regression analysis indicated that hypoproteinemia(OR,2.88[95%CI ,1.21-6.87]),body mass index ≥24(OR,3.11[95%CI ,1.12-8.66]),and blood loss≥400 mL(OR,3.98[95%CI ,1.36- 11.64])were independent risk factors for postoperative SSI,while CWEP use was the protective factor(OR,0.24[95%CI ,0.09-0.59]).Conclusion CWEP can effectively reduce the incidence of SSI following open abdominal surgery.

Object To provide the theoretical basis for the artificial planting of Hypericum perforatum L., the effects of light, gibberellin and ethephon on the germination of H. perforatum seeds were studied. Methods The method of direct germination was used. Results The seeds germinated to 79% in the light, while didn't germinate in the dark. Gibberellin and ethephon not only promoted the germination in the light, but also induced the germination in the dark. But ethephon inhibited the growth of seedling radicals severely. Conclusion The seed of H. perforatum is light-dependent seed, its light-dependence is related to gibberellin and ethephon.
