OBJECTIVE: To highlight concepts critical to achieving successful diagnosis and endoscopic therapy for lateral recess of the sphenoid sinus (LRSS) lesions, operative techniques, and avoiding complications in the treatment were discussed. METHOD: Pathology within a lateral recess of a widely pneumatized sphenoid sinus is difficult to access with the use of traditional open and current endoscopic surgical approaches. A new surgical procedure, the endoscopic tranapterygoid approach, directly accesses this region. A clinical experience over several years with this approach is reported as well as a refined and updated description of the technique. Twenty-six patients with LRSS lesions were retrospectively studied, from 2008 to 2013, 11 males and 15 females. Ages ranged from 21 to 68 years (mean 43 years). Radiological investigations consisted of computed tomography (CT) scan and magnetic resonance images (MRI) in all cases. An endoscopic tranapterygoid approach was performed in all patients under general aneasthesia, 4 to resect a middle fossa meningoencephalocele and repair the CSF leak and associated skull base defect. RESULT: All the operations were successful. Patients tolerated the approach well and no significant complications occurred. Post operative pathology made definite diagnosis. Meningoencephalocele 4 cases, sphenoid sinus cyst 10 cases (4 cases only were subtotal resected for it's tight adhesions with optic nerve or internal carotid artery) , fungal sinusitis 5 cases (non-invasive fungal sinusitis, pathogenic funga was aspergillus) chronic sphenoid sinusitis 5 cases. Nine patients had postoperative ipsilateral facial, upper lip and palatal hypesthesia, not given treatment, gradually relieved after 6 months. No recurrence was found during follow-up for 6 to 53 months (mean 23.8 months). CONCLUSION It had very important implications for high resolution CT combined with MRI in diagnosis of LRSS lesions. In selected cases, the endoscopic tranapterygoid approach enables the otolaryngologist to meet modern demands to treat conditions in the lateral sphenoid using minimally invasive techniques that are well-tolerated by patients. The endoscopic transpterygoid approach is an excellent approach for dealing with LRSS lesions.

OBJECTIVETo explore the clinical effects of Dynesys system combined with posterior lumbar interbody fusion (PLIF) in treating multiple lumbar degenerative disease.

METHODSThe clinical data of 46 patients with multiple lumbar degenerative diseases treated by Dynesys system combined with PLIF from September 2010 to May 2013 were retrospectively analyzed. There were 17 males and 29 females, aged from 38 to 68 years old with an average of (56.38±11.63) years. Operation section was in L2-L5 of 16 patients (6 with fusion of L4,5 and 10 with fusion of L4,5,L5S1) and in L3-S1 of 30 patients (11 with fusion of L5S1 and 19 with fusion of L4,5,L5S1). Patients were followed up for three times: postoperative 3 months, 1 year and final follow-up. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to assess clinical symptoms preoperatively and postoperatively. All patients underwent flexion/extension radiographs examinations before surgery and at final follow-up. Range of motion (ROM) and disc height index (DHI) were recorded.

RESULTSAll patients were followed up from 16 to 48 months with the mean of (23.23±7.34) months. At third follow-up after operation, ODI and VAS of lumbago and leg pain were significant improved than that of preoperative (P<0.01). DHI of fusion segment was significantly increased than that of preoperative (P<0.05). There was no significant difference in adjacent non-fusion segment between preoperative and postoperative (P>0.05). Postoperative ROM of fusion and non-fusion segments were obviously decreased than that of preoperative. There was no significant difference in ROM of upper adjacent non-fusion segment between 3 months and 1 year after operation (P>0.05), but at final follow-up, the ROM was increased (P<0.05).

CONCLUSIONThe preliminary clinical results of the Dynesys system combined with PLIF in the treatment of multiple lumbar degenerative diseases are satisfactory. It can be determined in fusion or non-fusion according to the individual needs and can reserve the some intervertebral motion, prevent the early degeneration of adjacent segments. However, its long-term clinical efficacy should be verified with long time.

To observe the clinical effect of compound Yimucao oral liquid on postpartum lochiorrhea. Methods:A to-tal of 200 patients with postpartum lochiorrhea were randomly divided into the observation group ( 100 cases ) and the control group (100 cases). The patients in the observation group received 20ml compound Yimucao oral liquid three times a day for seven days, while those in the control group were given 15g Yimucao granules three times a day for seven days. After the treatment, the duration, amount, color and quality of lochia, lower abdominal pain, uterine involution and the status of postpartum infection in the two groups were compared. Results: The total effective rate in the observation (94. 0%) was higher than that in the control group(84. 0%). Compared with that in the control group, less average hemostasis time, better situation of abdominal pain, uterine involution and lower postpartum infection rate in the observation group were observed after the treatment(P<0. 05). Conclusion:Compound Yimucao oral liquid can promote the uterine involution. It’ s effective and safe in the treatment of postpartum lochirrhea.

Objective To investigate the value of multi-slice spiral CT image texture analysis in differentiating metastatic (MLN) from non-metastatic lymph nodes (NLN) in patients with rectal cancer.Methods Thirty five patiets with rectal cancer who were pathologically confirmed by total mesorectum excision were included retrospectively,with regional lymph nodes (short-axis diameter of larger than 3 mm)found in preoperative CT images.All the patients underwent preoperative abdominal and pelvic dynamic contrast-enhanced CT scan.Regional lymph nodes were identified according to pathological findings,and were divided into MLN and NLN groups.The short-axis diameter,short-to long-axis diameter ratio of lymph nodes were manually measured and calculated,and the texture features,including skewness,kurtosis,variance,entropy and inverse difference moment,were analyzed.The above parameters between MLN and NLN groups were compared using independent sample t test or Mann-Whitney U test.ROC curve analysis was performed regarding the statistically significant parameters and the areas under curve (AUC) were calculated.Multivariate Logistic regression analysis was accomplished to obtain the independent predictive factor of diagnosing regional lymph nodes.Results A total of 68 regional lymph nodes were obtained and consisted of 31 MLNs and 37 NLNs.The short-axis diameter,kurtosis,and entropy of the MLN group were significantly higher than those of the NLN group (all P＜0.05).Whereas,the short-to long-axis diameter ratio,skewness,variance,and inverse difference moment did not differ significantly between the two groups (all P＞0.05).The AUC for distinguishing MLN from NLN of the short-axis diameter,kurtosis and entropy were 0.79,0.67,and 0.85,respectively.Multivariate logistic regression analysis showed that only entropy (odds ratio=8.48,95％ confidence interval was 3.01 to 23.92,P＜0.01) was screened out as the independent variable,which suggested that the entropy was the unique predictor for characterizing regional lymph nodes of rectal cancer.Conclusion Multi-slice spiral CT images texture analysis can facilitate the accurate differentiation between MLN and NLN in patients with rectal cancer,and especially the entropy has the optimal reference significance.

OBJECTIVETo compare the difference of Euphorbia Pekinensis Radix before and after being processed with vinegar in the toxicity on rat small intestinal crypt epithelial cells IEC-6, and make a preliminary study on the mechanism of detoxication of Euphorbia Pekinensis Radix processed with vinegar.

METHODWith rat small intestinal crypt epithelial cells IEC-6 as the study object, the MTT method was adopted to detect the effect of Euphorbia Pekinensis Radix before and after being processed with vinegar on IEC-6 cell activity. The morphology of cells were observed by the inverted microscope. The down-regulated mitochondrial apoptosis pathway of enterocytes caused by the vinegar processing was analyzed by using the high content screening.

RESULTCompared with the negative control group, the proliferation inhibition experiment showed that Euphorbia Pekinensis Radix showed a relatively high intestinal cell toxicity (P < 0.01). The results of HCS analysis showed that Euphorbia Pekinensis Radix could significantly reduce the cell nucleus Hoechst fluorescence intensity and mitochondria membrane (P < 0.05, P < 0.01), and increase Annexin V-FITC and PI fluorescence intensity and membrane permeability (P < 0.01, P < 0.01, P < 0.01). After being processed with vinegar, compared with Euphorbia Pekinensis Radix groups with different doses, Euphorbia Pekinensis Radix processed with vinegar could significantly decrease the cell proliferation inhibition effect on enterocytes, increase the cell nuclear Hoechst fluorescence intensity and mitochondria membrane (P < 0.05, P < 0.05), and decrease Annexin V-FITC and PI fluorescence intensity and membrane permeability (P < 0.01, P < 0.01, P < 0.05), and showed a certain dose-effect relationship.

CONCLUSIONThe vinegar processing can further reduce the toxicity of Euphorbia Pekinensis Radix on enterocytes. Its possible mechanism can decrease the effect of Euphorbia Pekinensis Radix on the permeability of IEC-6 cell membrane, so as to provide a basis for further explanation of the detoxication mechanism of Euphorbia Pekinensis Radix processed with vinegar.
