Statistical analysis of TCM syndrome differentiation and clinical symptoms were made in 163 cases of diseases of digestive tract. It was found that the patients of abnormal defection or tendecy of abnormal defecation with the hyperactive liver - Qi attacking the spleen, stagnation of liver-Qi due to hypofunction of the spleen, loose stool due to deficiency of the spleen, constipation due to Qi-deficiency, constipation due to Qi - staganation syndromes accounted for 60%- 100%. Elecrtic examination of colon on the body surface and analysis of frequancy spectrum found that hyperelectroactivity of low - frequency and high - frequency segment of colon and contractive complex myoelectric hyperactivity in the patients of the hyperactive liver - Qi attacking the spleen; hyperelectroactivity of high - frequency segment of the ascending and descending colon and contractive complex myoelectric hyperactivity and decrease of electric activity of high - frequency segment of the sigmoid colon in the patients of loose stool due to hypofunction of the spleen: obvious decrease of electric activiy of low - frequency and high-frequency of the colon and contractive complex myoelectric hyperactivity in the patients of constipation due to deficiency of Qi or Qi - stagnation, but electric activity of the high -frequency segment of the colon and contractive complex myoelectric activity after meal in the patients of constipation due to Qi -stagnation was stronger than that in the patients of constipation due to Qi - deficiency. Electric frequency spectrum of colon can indirectly reflect changes of colon dynamics of different syndromes, and it can partially expain the changes of stool and the mechanism of relative symptoms.

sweet potato. Conclusion The content of arsenic (Ⅲ) in the edible part of plants was one of the important factors for selecting the plants that are suitable for growing the arsenic polluted area.

Objective To evaluate the clinical value of ultrasonography in diagnosis of benignPHand malignant thyroid nodules by binary Logistic regression model.Methods A retrospective analysis of 240 cases of thyroid nodules confirmed by pathology after operation excision was conducted.173 nodules were benign as control group,67 nodules were malignant as observation group.The ultrasonic features of thyroid nodules were collected.The factor had statistics significance by x2 test between the two groups were analyzed by binary Logistic regression.A logistic regression model was created.The ROC curve was drawn and the area under the curve was calculated.Results There were statistically significant differences among boundary,aspect ratio,shape,internal echo,calcification,acoustic halo,cervical lymphadenectasis between the control group and observation group(x2=45.392,7.590,30.039,24.168,37.406,6.893,16.078,all P<0.01).And after Logistic regression analysis,six variables that entered the regression equation were boundary(P=0.000,OR=8.437),aspect ratio(P=0.000,OR=12.816),microcalcification of the nodules(P=0.000,OR=8.893),shape(P=0.000,OR=8.791),internal echoes(P=0.001,OR=8.313)and cervical lymphadenectasis(P=0.001,OR=6.891).The accuracy of the model was 90.7%(223/246)in predicting malignant nodules in thyroid.The area under the ROC curve was(0.904±0.031).Conclusion The binary Logistic regression can be used to differentiate malignant and benign thyroid nodules,and make a more accurate judgment for the nodules in thyroid.

Objective To explore the method and result of endoscopic thyroidectomy. Methods Thyroidectomy was performed endoscopically in 4 cases of thyroidoma. Results 4 patients underwent endoscopic thyroidectomy, whose operation time was 52,63,70,75 minutes respectively. An average blood loss during operation was 35ml and no complication occurred. They were discharged 4 days～5 days after operation. Conclusions The endoscopic thyroidectomy has the advantages of minimal invasion, less bleeding, less complication and quicker recovery.

OBJECTIVE:To evaluate the quality of the methodology of clinical research on Yinzhihuang injection in the treatment of icteruc virus hepatitis.METHODS:The methodology quality of77pertinent literatures was evaluated and analyzed according to the quality assessment criteria in the evaluation manual of Cochrane Reviewer's Handbook 4.2.2.RESULTS:Only 4 literatures were up to the related standards,2 of which were randomized controlled trials(RCT)and other 2 were semi-randomized controlled trials(CCT).All of the 4 studies were low quality(Grade C)researches,in which the biases on selectivity,practice,measurement and wastage were highly possible.CONCLUSION:More randomized controlled trials of high quality are needed to obtain reliable evidences on Yinzhihuang injection in the treatment of icteric virus hepatitis.

Objective To explore the relationship between recurrent spontaneous abortion and the chromosome abnormality by analyzing the 394 couples′chromosome karyotypes.Methods Peripheral blood lymphocytes in 394 couples of recurrent spontane-ous abortion in Guangzhou area were cultured and performed the chromosome karyotype analysis.Results Among 394 couples of recrudescence abortion,41 cases (5.2%)of abnormal chromosome karyotypes were detected including 1 case(2.44%)of chromo-some number abnormality,8 cases (19.51 %)of balanced translocation,3 cases (7.32%)of Robertsonian translocation,1 case (2.44%)of chromosome inversion and 28 cases (68.29%)of chromosomal polymorphism.Conclusion The chromosomal abnor-mality is an important reason for recurrent spontaneous abortion.Recurrent spontaneous abortion is not only associated with anoma-lies of chromosome structure,and could have a certain relationship with chromosome polymorphism.

BACKGROUND: A skull defect is inevitable after decompression treatment for traumatic brain injury. Titanium mesh as the most recognized skull repair material has good biocompatibility and has been widely used in clinical practice. However, the timing for skull repair after brain injury is still in dispute.OBJECTIVE: To compare the changes of brain perfusion and the recovery of neurological function in patients with skull defects before and after early and late-stage titanium mesh repair based on CT perfusion technique.METHODS: This was a single-center, prospective, observational clinical trial that was completed at the Taihe Hospital,Hubei University of Medicine in Hubei Province, China. Eighty-six patients with craniocerebral injury who had undergone decompression with removal of bone flap from January 2013 to January 2016 were recruited and subjected to skull repair using titanium mesh. All the patients were randomized into two groups: test group (n=40) with early skull repair within 1-3 months after decompression and control group (n=46) with late-stage skull repair within 6-12 months after decompression. CT perfusion technology was used to observe changes of brain perfusion at 3 days operatively and at 10 days postoperatively. The Barthel index was evaluated at 30 days postoperatively. The trial was registered with ClinicalTrial.gov (identifier: NCT03222297) on July 12th, 2017. The study protocol was approved by the Ethics Committee of Taihe Hospital with the approval No. 2012 (08), and performed in accordance with the Declaration of Helsinki,formulated by the World Health Organization and the hospital's ethical requirements for human research. All the patients and their families were voluntary to participate in the trial, were fully informed of the trial process, and then signed the informed consent prior to the initialization of the trial.RESULTS AND CONCLUSION: The postoperative cerebral blood volume and cerebral blood flow at the parietal cortex on the side of skull defect and at the cortex in the defect region were significantly higher in the two group than the baseline (P < 0.05), while the time to peak was lower than the baseline (P < 0.05). Compared with the control group,significantly higher cerebral blood volume and cerebral blood flow as well as shorter time to peak were observed in the test group (P < 0.05). The Barthel index of the test group was also significantly higher than that of the control group at 30 days postoepratively (P < 0.05). Overall, early skull repair with titanium mesh is helpful to improve the cerebral blood perfusion at the affected side and the recovery of neurological function. In addition, CT perfusion technology is a safe and effective method to monitor hemodynamic changes in the brain.
