BACKGROUND:Navigation assisted minimal y invasive posterior lumbar interbody fusion and pedicle screw fixation can precisely real-time guide a variety of operation under minimal y invasive sleeve, and implant the pedicle screws and interbody fusion cage and other implants safely and accurately, thus can determine the decompression parts. Minimal y invasive transforaminal lumbar interbody fusion is the typical approach in recent years for the successful application of minimal y invasive spine surgery techniques with the advantages of smal incision, less bleeding, slight tissue damage and faster recovery. OBJECTIVE:To evaluate the short-term effect of minimal y invasive transforaminal lumbar interbody fusion with real-time three-dimensional navigation system and open posterior transforaminal lumbar interbody fusion. METHODS:Forty cases with single-level lumbar disc herniation were retrospectively analyzed. The patients were treated with minimal y invasive transforaminal lumbar interbody fusion with real-time three-dimensional navigation system (20 cases) and open posterior transforaminal lumbar interbody fusion (20 cases) respectively for the comparative analysis. The fusion duration, intraoperative blood loss, postoperative drainage volume, the length of postoperative hospital stay and the length of hospital stay were compared between two groups. The wound pain and function were evaluated after treatment with visual analogue scale score and Japanese Orthopaedic Association score. RESULTS AND CONCLUSION:Al patients were fol owed-up for 7.7 months. The operative duration in the minimal y invasive transforaminal lumbar interbody fusion group was longer than that in the open posterior transforaminal lumbar interbody fusion group, and the difference was significant (P<0.01);the length of hospital stay and length of postoperative hospital stay of the minimal y invasive transforaminal lumbar interbody fusion group were shorter than the open posterior transforaminal lumbar interbody fusion group, and the differences were significant (P<0.01);the intraoperative blood loss of the minimal y invasive transforaminal lumbar interbody fusion group was less than the open posterior transforaminal lumbar interbody fusion group, and the difference was significant (P<0.05);the postoperative drainage volume of the minimal y invasive transforaminal lumbar interbody fusion group was less than the open posterior transforaminal lumbar interbody fusion group, and the difference was significant (P<0.01). The visual analogue scale score was significantly decreased and the Japanese Orthopaedic Association score was significantly increased in the minimal y invasive transforaminal lumbar interbody fusion group at 3 days after internal fixation compared with open posterior transforaminal lumbar interbody fusion group (P<0.01), but there were no significant differences in the visual analogue scale score and Japanese Orthopaedic Association score between the two groups before operation and 6 months after operation (P>0.05).The results indicate that minimal y invasive transforaminal lumbar interbody fusion with real-time three-dimensional navigation system is an effective method for lumbar disc herniation with the advantages of less intraoperative blood loss, less postoperative drainage volume, smal trauma, short hospital stay and short-term efficacy.

Objective To investigate the regularity of intrapulnonary lobar and segmental lymph nodes metastasis in patients with cT1N0M0 stage lung adenocarcinoma.To provide a basis for more accurate determination of N stage and indication for pulmonary segmental resection.Methods A prospective study was performed from March 2014 to December 2015.103 cases of cT1 N0M0 stage lung adenocarcinoma received lobectomy and mediastinal lymph node dissection in the thoracic surgery department of China-Japan Friendship Hospital.Intrapulmonary lobar and segmental lymph nodes were dissected and sorted carefully then sent to the pathological department with the corresponding lung specimen and other lymph nodes.Statistical analysis was carried out considering size of the lesion,imaging features,serum CEA levels,pathological subtypes and so on.Results In total 103 cases,pN0 was confirmed in 82 cases,pN1 in 15 cases,pN1 + N2 in 5 cases,and skipping-pN2 in 1 case.14 cases(93.3％) in pN1 group were detected with station 12-14 lymph node metastasis,while only 5 cases (33.3％) were detected with station 12-14 LSNs metastasis.4 cases(66.7％) in pN2 group were detected with station 12-14 lymph node metastasis,while only 1 case(16.7％) with station 13 and station 7 lymph node metastasis.If LSNs were not detected,the false negative rate of N staging could be as high as 6.1％ (5/82),The rate of missed diagnosis of lymph node metastasis might be 30％ (6/20) to N1 stations alone.41.2％ (7/17)cases with metastasis to the adjacent LSNs had been proved with metastasis to the isolated LSNs.The metastasis rate of the isolated LSNs was significantly lower(P =0.049) in pure GGNs compared with those part-solid/solid nodules.Invasive adenocarcinoma had higher metastasis rate of isolated LSNs,compared with preinvasive lesions or minimally invasive adenocarcinomas,with no statistical difference between groups (P =0.055).No significant difference in isolated LSNs metastasis rate was found between groups with different serum CEA levels(P =0.251) or tumor size(P =0.197).Conclusion Dissection of intrapulmonary lobar and segmental lymph nodes might facilitate a more accurate N stage,reduce the false negative rate of lymph node metastasis,and provide basis for more accurate assessment of prognosis and postoperative adjuvant treatment.The sampling area of lymph nodes during segmental resection should include the adjacent LSNs of the target segment.The isolated LSNs metastasis rate of cT1N0M0 stage lung adenocarcinoma with pureGGN as imaging feature is relative low,which might be suitable for segmentectomy when meeting other criteria.

Objective: To evaluate the effect of echocardiography for occluding the multiple seconded atria1 septal defects ( MASD) in relevant patients.
Methods: A total of 42 MASD patients were selected by transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE). The transcatheter closure was monitored by TTE and X-ray, the effect of treatment was evaluated by TTE, ECG and chest X-ray at 24 hours and 1, 3, 6 months after the procedure. There were 38 patients with 2 defects, 3 with many central small defects and 1 with 3 defects. The patients included 17 male and 25 female with the mean age of (32.6 ± 13.4) years.
Results: The size and distance of the defects were measured with 4 cardiac chambers cross sectional study. The mean diameter of bigger defect from up to down was (9-27) mm, with the mean of (20.7 ± 6.1) mm, from front to back was (8-23) mm, with the mean of (16.9 ± 5.7) mm;the mean diameter of small defect from up to down was (3-12) mm, with the mean of (6.8 ± 3.6) mm. The length of the defect interva1 was (4-18) mm, with the mean of (7.9 ± 2.6) mm. There were 4 patients with 2 defect interval at 8.7 mm who received 2 occluders without post-operative lfow shunt. The rest 38 patients received 1 Amplatzer occluder which was (14-36) mm with the mean of (25.1 ± 6.4) mm which was (6.9 ± 1.7) mm larger than echocardiographic prediction. The success rate of implantation was 100%. There were 17 (40.5%) patients with post-operative lfow shunt. The patients were followed-up for (6-36) months, with the mean of 18.7 months, there were 11 (26.2%) patients with small amount of lfow shunt at 3 months after the operation.
Conclusion: Echocardiography is important for choosing the type and size of occluder devices, in-operative monitoring and post-operative effect evaluation for treating the ASD patients.

OBJECTIVETo establish a HPLC method for the determination of gallic acid and catechin in Rheum palametum and to study the changes of gallic acid and catechin content in R. palametum during processing.

METHODThe contents of gallic acid and catechin were determined simultaneously by HPLC on the Zorbax Eclipse XDB-C18 (4.6 mm x 250 mm, 5 microm) column at 30 degrees C with gradient elution. The flow rate was 0.9 mL x min(-1) and the detecting wave-length was 277 nm.

RESULTThere were obvious differences in contents of gallic acid and catechin between the crude herbal material and other four kinds of processed products of R. palametum. Compared to crude herbal material, the contents of gallic acid increased evidently increased in the five processed pieces, up to 139. 3% in the processed piece of braising with liquor. The contents of catechin were similar to gallic acid in the pieces of vinegar and the liquor sauted, but nearly not founded in the braising with liquor and the charring products.

CONCLUSIONThe different processing methods have certain effect on the content of gallic acid and catechin in R. palametum.
