Objective To investigate the necessary and feasibility of fistulous tissue-saving anorectoplasty for low anorectal malformation with fistula in children.Methods The clinical data of 67 cases of low anorectal malformation with fistula were analyzed retrospectively, there were 59 girls with rectovestibular fistula, 8 boys with rectoperineal fistula. The patients′ average age were 10 months, ran -ging from 3 months to 16 years. The clinical manifestations of all patients were intractable constipation, or out of position of anus. Cut-back procedure had been performed on 4 patients in infancy. The anterior sagittal anorectoplasty was performed in all cases.Results In all cases returned for follow-up at 3 and 6 months after operation, the longest was 8 years. The postoperative course of 65 patiens was uneventful without wound infection, and had a normal-looking perineum, other 2 cases with anal rupture in operation were with sagittal wound infection resulted from perforation in repairing anus, and formed finally rectoperineal fistula with a normal-looking anus. Sixty-four cases (95.5%) had good continence by 5-6 score, another 3 cases (1 boy, 2 girls) with intractable constipation defecated with help of Glycerinum.Conclusions The fistulous tissue-saving anterior sagittal anorectoplasty is a reliable and feasible procedure for low anorectal malformation with fistula. This operation provides good results.

Objective To ascertain the level and dynamic changes of environmental health hazards in the rural areas of Pukou, Nanjing, to objectively evaluate the situation of rural environmental sanitation, providing basis and support for formulating policies and measures by the higher authorities. Methods According to the requirements of the rural environmental sanitation monitoring program of Jiangsu Province in 2017, 5 streets, 20 administrative villages were selected as monitoring points and 100 families used as monitoring objects.The monitoring data were obtained through interviews, access data, field records and laboratory tests. Results Centralized water supply was realized by 20 monitoring points.The rate of collection and centralized disposal of domestic waste was 95.00%.The sewage disposal sites were mainly discharged into sewage treatment plants and harmless sanitary toilets, accounting for 41.00% and 42.00% respectively.The coverage rate of sanitary toilets was 95.54%.Those who did the work of killing rats, flies and mosquitoes accounted for 40.00% and those who did the work of killing cockroaches 25.00%.And 98.00% of the families used fuel for gas, 98.00% of the families never burned straw in the fields, 88.00% of the families did not use the film, and the membrane recycling rate was 91.67%.It was found that 100% of the households drank boiled water, and 90.00% of the respondents developed the habit of washing hands before and after meals.The detection rate of Ascaris eggs was 20.00% in 20 soil samples, and the contents of Pb, CD and Cr were all within the normal range. Conclusion Although some achievements have been made in the rural environmental sanitation in Pukou, the management of pollution of rural sewage, waste and feces should be further strengthened, and the dangerous factors that affect the health of rural residents should be decreased and four pests removal activities actively carried out.

OBJECTIVETo assess the clinical effect and safety of the Chinese medicine Longbishu Capsule combined with mesylate doxazosin in the treatment of benign prostatic hyperplasia (BPH) of the kidney deficiency and blood stagnation type.

METHODSThis was a randomized, double-blind, double-simulation control study. We equally assigned 60 men diagnosed with BPH of the kidney deficiency and blood stagnation type to an experimental and a control group, the former treated with mesylate doxazosin plus Longbishu Capsule and the latter with mesylate doxazosin plus placebo. We compared the International Prostate Symptom Score (IPSS), quality of life (QOL), Chinese symptom score (CSS), maximal urinary flow rate (Qmax), and prostate volume between the two groups of patients before and after 6 months of medication.

RESULTSAfter treatment, there were 5 cured cases, 13 markedly effective cases, 9 effective cases, 1 ineffective case, and 2 eliminated cases in the experimental group, as compared with 2 cured cases, 8 markedly effective cases, 10 effective cases, 7 ineffective cases, and 3 eliminated cases in the control group. The total effectiveness rate was obviously higher in the former (96.4%) than in the latter (74.1%). IPSS, Qmax, and CSS were improved in both of the groups after medication, even more significantly in the experimental than in the control group (IPSS: 15.22 ± 2.98 vs 18.15 ± 5.88, P <0.05; Qmax: [13.56 ± 2.26] ml/s vs [11.78 ± 2.97] ml/s, P <0.05; CSS: 6.18 ± 2.13 vs 9.52 ± 3.15, P <0.05). Because of the difference in the QOL score between the two groups at the baseline (P = 0.038 <0.05), no more comparison was made in this aspect after treatment.

CONCLUSIONThe combination of Longbishu Capsule with mesylate doxazosin is safe and effective for the treatment of BPH.

OBJECTIVESTo explore the relationships between the peripheral blood levels of CD61, CD63, PAC-1 and the incidence of acute rejection and tubular necrosis after renal transplantation, and recovery of the graft function.

METHODSThe peripheral blood levels of CD61, CD63, and PAC-1 of 86 patients with uremia in different stages before and after transplantations were analyzed by flow cytometry. The patients were divided into three groups: (1) twenty-nine patients with normal grafts function, (2) hirty with acute rejection and (3) twenty-seven with acute tubular necrosis. The patients with acute rejection were randomly divided into treatment group with anticoagulants and cntrol group.

RESULTSThe peripheral blood levels of CD61, CD63 and PAC-1 significantly increased (P < 0.05) in the patients with acute rejection, in comparison with those with normal grafts function and those with acute tubular necrosis. The peripheral blood levels of CD61, CD63 and PAC-1 in patients with acute rejection in anticoagulants therapy was lower, recovery time of the grafts function was shorter, one-year survival rates of patients and grafts were higher, as compared with those of controls.

CONCLUSIONSThe patients with acute rejection have significantly high peripheral blood levels of CD61, CD63 and PAC-1 before transplantation, however, these values in patients with acute tubular necrosis are not high, this suggesting that acute rejection might relate to platelet activation, while acute tubular necrosis might not relate to it. After anticoagulants therapy in patients with acute rejection, the grafts function might recover faster and their one-year survival rates and grafts might be higher in those with CD61, CD63 and PAC-1 decreasing remarkably.

OBJECTIVETo seek a safe, efficient, and cost-effective technique for local thermo-ablation of hepatic cancer.

METHODSThe livers from 16 healthy rabbits were thermocoagulated by diode-laser with scanner fiber tip, 6 w for 10 mins. At the same time, the temperatures were measured at 0, 5 and 10 mm from laser tip. The pre-thermocoagulative liver function was compared with that of 7 days post-thermocoagulation. The pathologic changes were also observed 1 month after laser thermocoagulation.

RESULTSAll the rabbits survived and hepatic tissue temperatures at 0, 5, 10 mm from laser tip reached 96.39 degrees C +/- 3.97 degrees C, 60.79 degrees C +/- 6.21 degrees C, 46.10 degrees C +/- 4.58 degrees C respectively after 10 minutes of thermocoagulation. There were no significant differences in liver function parameters between rabbits of pre-laser thermocoagulation and of post-laser thermocoagulation. Thermocoagulated necrosis of liver tissue with surrounding fibrosis in a diameter of 26.0 mm was formed. Light microscopy revealed coagulative necrosis in the center of the coagulated area without surviving hepatic cells.

CONCLUSIONThe hepatic tissue can be coagulated safely and effectively by diode-laser with scanner fibertip, and such a technique may provide a new method for the treatment of hepatic carcinoma.

OBJECTIVETo evaluate and analyze the mechanism of Pizhen for the treatment of patients with scapular muscle fasciitis.

METHODSOne hundred and sixteen patients were divided into two groups according to random number table method, 58 cases in the treatment group and 58 cases in the control group. After treatment, 109 patients were followed up, and 7 patients lost follow-up (2 cases in the treatment group and 5 patients in the control group). In the treatment group, there were 15 males and 41 females, with a mean age of (28.02 +/- 4.85) years; the course of disease ranged from 0.25 to 3 years; and the patients were treated by Pizhen once a week,and 2 weeks were one treatment course. In the control group, there were 19 males and 34 females, with a mean age of (27.23 +/- 4.54) years old; the course of disease ranged from 0.25 to 1 year; and the patients were treated by acupuncture massage instrument, 20 minutes at a time,once a day for 2 weeks. Soft tissue displacement and banana area were tested by a soft tissue tension tester, pressure value was measured by pressure measuring instrument, and VAS was recorded by pain visual analog scale record.

RESULTSThere were significant differences in tissue displacement, banana area, pressure value and VAS between two groups before and after treatment. The tissue displacement and pressure value in the treatment group were higher than those in the control group,while banana area and VAS were lower than those in the control group. In the treatment group, 30 patients healed, 13 patients got marked improvement, 12 good and 1 poor;while 16 patients healed, 19 patients got marked improvement,11 good and 7 poor in the control group. The therapeutic effects in the treatment group was better than that in the control group.

CONCLUSIONPizhen is an effective method to treat pain in patients with scapular muscle fasciitis by relaxing tendon of soft tissue around pain point of scapular and relaxing compress and stimulation of nerves.

Objective:To study the effect of apparent diffusion coefficient(ADC) of MRI in surgical resection of high risk breast lesions.Methods: 244 patients with high risk breast lesions(235 breast lesions) were enrolled this study, and the lesion region and the ADC of MRI in contralateral normal breast were analyzed and compared.Results: In the 224 patients, all of the 235 breast lesions received puncture or relevant surgery confirmation. In the 235 lesions, there were 158 lump lesions, and the ADC of malignant lesion was (1.04±0.2)×10-3mm2/s, the ADC of benign lesion was(1.47±0.32)×10-3mm2/s, and the difference of the two ADCs was significant(t=14.964, P<0.05). In non-lump lesions were 77, the ADC of malignant lesion was(1.18±0.33×10-3mm2/s, the ADC of benign lesion was(1.51±0.3)×10-3mm2/s, and the difference between them was significant(t=9.243,P<0.05). The cut-off of ADC was determined according to receiver operating characteristic(ROC) curve, and it was identified as malignance when ADC was less than 1.25×10-3mm2/s. Besides, the sensitivity and the specificity were 78.1% and 77.8%, respectively, and the area under the ROC curve was 0.817.Conclusion: The ADC value of patients with high-risk breast lesions who received surgical resection is lower than that of benign lesion, and the malignant and benign lesion can be identified according to cut-off value of ADC. And there is difference of ADC value between lump lesion and non-lump lesion. Besides, the cut-off value of ADC of lump lesion is smaller than that of non-lump lesion.
