Chinese Journal of Postgraduates of Medicine 2012;35(3):25-27
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.

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 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 study 18F-FDG PET/CT and enhanced CT in the evaluation of resectability of pancreatic cancer.Methods The 18F-FDG PET/CT and enhanced CT images of patients with pancreatic cancer were analyzed and the results in assessing resectability were compared.The diagnosis of pancreatic cancer and resectability were confirmed by intraoperative findings and histopathology.Results 31 patients with pancreatic cancer underwent surgery.Complete resection of the tumor was successfully carried out in 18 patients.Palliative operations were performed in the remaining 13 patients because the tumors were unresectable.The sensitivity,specificity and accuracy for unresectabilitywere 94.4%,15.3%,61.2% using enhanced CT,94.4%,38.4%,70.9% using 18F-FDG PET/CT,and 88.8%,53.8%,71.3% using a combination of these two examinations,respectively.There was no significant difference between enhanced CT and 18 F-FDG PET/CT.A combination of these two examinations was significantly better than either one of these examinations.Conclusions Either enhanced CT or 18F-FDG PET/CT was useful,and they complemented each other in assessing resectability of pancreatic tumor.A combination of these two examinations was more evaluable than either one of these examinations.
