Objective To analyze postoperative effect of a new rectopexy technique with Douglas pouch elevation for complete rectal prolapse (CRP) in adults.Methods From January 2010 to May 2011, 52 CRP cases were treated by rectopexy with Douglas pouch elevation.In terms of different surgical techniques, patients were divided into two groups : Group A (n =28) received laparoscopic rectopexy with Douglas pouch elevation;and Group B (n =24) received laparoscopic rectopexy with Douglas pouch elevation combined with procedure for prolapse and hemorrhoids (PPH).Rectal prolapse, constipation, and fecal incontinence in the two groups were assessed respectively before surgery, and on the 6th, 12th, and 24th month after surgery, postoperative complications were evaluated with severe grading of surgical complications.Results Symptoms of rectal prolapse disappeared at half a year after surgery in all patients, and relapsed to different extent afterwards.However, two years after operation, the status of rectal prolapse in Group B tended to be stable.The trend of constipation after surgery was consistent with that of rectal prolapse.In addition, fecal continence improved gradually on half a year after surgery in the two groups and recovered to the optimal status in the first postoperative year.However, in the second year, the results of fecal incontinence reduced slightly in Groups A, and Group B became stable.Two years after surgery, four cases in Groups A relapsed while there was no recurrence in Group B.Difference of Grade I to Grade Ⅲ complications among the two groups was statistically insignificant (x2 =0.05, P ＞ 0.05).Conclusions The clinical effect of laparoscopic rectopexy with Douglas pouch elevation associated with the procedure for prolapse and hemorrhoids (PPH) is better than that without PPH for female and male CRP patients with severe symptoms.

Objective To find out the pathologic changes and possible influencing factors in the process of spontaneous regression of plane warts.Methods One hundred and five lesional specimens taken from patients with plane warts were observed microscopically.Results The histologic features indicated slight hyperkeratosis,acanthosis and ballooning degeneration of keratinocytes in stable lesions;a combination of tower-peak shaped hyperkeratosis,cuneate hypergranulosis and ballooning degeneration in progressively increasing lesions;and infiltration of lymphocytes and necrosis of keratinocytes in inflammatory icthing lesions.Conclusions Specific cell-mediated immunity against keratimocytes may be involved in the process of regression of plane warts.There is a positive correlation between the activity of skin lesions and the induction of cellular immunity.

Objective To treat scalp lacerations by using the hair apposition technique (HAT) and to compare the HAT with standard suturing in a controlled prospective trial. Method Fifty patients with scalp lacerations were treated either by HAT or by standard suturing. Two groups were evaluated in consumed times for operation, pain sores, and complications. Results There were 30 HAT patients and 20 patients treated with suturing. The took shorter operation time consumed[(3.33 vs. (6.05 t = 4.85.P < 0.01], and HAT produced significantly lower pain score [(1.73vs. (3.20t = 4.01,P < 0.01]. There was a trend that more and more patients were willing to have HAT performed. Conclusions The advantages of HAT include a shorter time consumed for operation, less pain, satisfactory wound healing, and high acceptance by patients. HAT is acceptable for treating scalp lacerations in emergency room.

Objective To study the relationship between the selection of tube tension in digitalchest radiograph and image quality.Methods When tube current was fixed at 4 mAs, the choice of X-ray tube voltage changed from 60 to 120 kV.CDRAD2.0 contrast details phantom and normal human chest were exposed by X-ray system with 7 kinds of tube voltage (the difference between tube voltage was 10 kV) ,and the X-ray incidental dose of phantom surface was measured.Five radiologists with 3 years working experience evaluated the image quality on monitor and calculated the image quality factor (IQF) and image reading score.Statistics analysis was then performed by using ANOVA test and t test.According to the results, the optimum tube voltage range was determined.Results (1) The incidental dose of phantom surface increased with the higher tube voltage.(2)When the tube voltage was changed from 60 kV to 120 kV, the IQF value observed in CDRAD2.0 phantom image on monitor was 75.0±10.4,57.1±6.4,52.7±2.5,47.9±4.5, 46.0±3.8,46.0±2.8,45.2±3.5 ,there was significant statistical differences between groups(F=19.10, P<0.01).(3)The integrated score of the chest image quality in the tube voltage 90 kV and 120 kV were 12.4±0.9 and 13.0±0.7, respectively, and there was no statistical difference between two groups(t= 1.500,P>0.05).Conclusions (1)With the increase of tube tension,the display capacity of display device gradually strengthened.When the tube tension exceeded 90 kV, the increase of image quality on monitor was not evident.(2) With proper radiation dose, the value of tube tension in digital X-ray chest photograph was about 90 kV.

Objective Our previous study showed that cycloxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) are expressed in choroidal neovascularization (CNV) and the expression of COX-2 is prior to VEGF, indicating that COX-2 is probably one of upstream regulatory factors of VEGF. The aim of this study was to observe inhibition and mechanism of intravitreous injection of celecoxib, a selective COX-2 inhibitor, on experimental choroidal neovascularization in a laser-induced rat model. Methods Retinal photocoagulation was performed in 36 right eyes of 36 male Brown Norway rats to establish CNV models with the laser parameter as follows:wavelength 532 nm, power 80 mW, spot diameter 100 p, m and time shutter 100 ms. Eight or ten spots were irradiated in the position of 1.5 - 2. 0 PD to optic disc. Celecoxib or normal saline solution was intravitreously injected via scleral incision in 18 right eyes of 18 rats, respectively. The thickness and area of CNV were qualified by HE staining(n =3) and by choroidal flatmount (n =3) at day 14 after photocoagulation under the light microscope. The expressions of VEGF and COX-2 in RPE-choroid-sclera complex were examined by Western blot(n =6) and RT-PCR(n =6) at day 7 after photocoagulation. The experimental procedure followed the Standard of Association for Research in Vision and Ophthalmology. The license for animal administration was obtained. Results After intravitreous injection with celecoxib, the thickness and area of CNV were significantly smaller in celecoxib group than normal saline group on 14 days (69. 75 μm ± 7. 50 μm vs 45. 84 μm ± 5. 59 μm in thickness and 87 854 pixel~2 ± 6 735 pixel~2 vs 61 101 pixel~2 ± 6 314 pixel~2 in area, P =0.00). The expressions of VEGF protein and mRNA were obviously lower in celecoxib group compared with normal saline group(t = 3. 755, P = 0.02; t =3. 155, P =0. 03) . No significant difference was found in expression of COX-2 mRNA between the two groups (t = 0. 581, P = 0. 59). Conclusion Intravitreous injection of celecoxib can effectively inhibit CNV by downregulating VEGF level, which is a new approach for the treatment of CNV.

Objective To explore the genuineness of Exocarpium Citri Grandis(ECG) from Huazhou city of Guangdong province.Methods We used the method of high performance liquid chromatography to detect the naringin content in ECG from different producing areas of Huazhou city.Random amplified polymorphic DNA analysis was used for the examination of genetic distance,and plasma-atomic emission spectrometry for the detection of soil elemental abundance of 8 elements such as aluminium(Al),kalium(K),calcium(Ca),ferrum(Fe),titanium(Ti),boron(B),magnesium(Mg),and manganese(Ma).The correlation of the above three parameters was analyzed by statistical software SPSS 11.5.Results Ca abundance in the surface soil layer had an obvious effect on the content of naringin,and the difference of Al and K abundance in subsoil layer was correlated with the genetic distance of ECG.Conclusion The genuineness of ECG is probably related with the abundance of phlopopitum in the soil of producing areas of Huazhou city.

Objective To investigate the interference effects of vitamin C on three different detection methods of blood glucose.Methods According to CLSI EP7-A2 document,5% volume of vitamin C(series concentrations) solution was added to fresh mixed serum,then hexokinase method(A),glucose oxidase method(B) and glucose reductase electrode method(C) were used to detect the level of fresh mixed serum glucose.The interference level of vitamin C on three different detection methods of blood glucose was evaluated.Results In 1 250 mg/L vitamin C,there was no interference on the method A for detecting blood glucose.In 156 mg/L vitamin C,it caused unacceptable negative interference on the method B and unacceptable positive interference on the method C.Moreover the interference degree of these two methods was increased with vitamin C concentration increase,but the same concentration of vitamin C had no significant difference on detecting different blood glucose levels by the same detection method.Conclusion High concentration of vitamin C can cause significant interference on glucose detection by glucose oxidase method and glucose reductase electrode method.
