Objective To investigate the micrometastases of No 13 lymph node in gastric carcinoma. Methods In this study, the expression of CK20mRNA, a specific tumor marker of gastric carcinoma, was detected by RQ-PCR for No. 13 group lymph node micrometastasis in 44 gastric carcinoma patients undergoing D2 radical gastrectomy plus No 13 lymph node dissection. Patient's survival was compared with those of 49 gastric cancer eases receiving standard D2 gastrectomy. Results No 13 lymph node micmmetastasis was detected in 11 out of the 44 gastric cancer cases (25%). Micrometastasis was correlated with tumor histological type (P < 0.01) such as mucoid adenocarcinoma and ring cell carcinoma, but not with age, sex, tumor location, tumor size, Bonnann type, depth of invasion (P > 0.05). Group No13 lymph node micrometastasis was detected in 2 out of 6 cases with positive No[2 lymph nodes and in 4 out of 11 cases with positive No14 lymph nodes, the differences were significant with P <0.01, and P < 0.01 respectively, when compared with those with negative No12 lymph nodes and No14 lymph nodes. After a respective median 448 and 419 days follow-up, no obstructive jaundice caused by No 13 lymph node metastasis was detected after No 13 lymph node dissection in radical gastrectomy for gastric carcinoma and such obstructive jaundice was found in one case in the control group. However, there was no significant difference in tumor recurrence between the two groups (Log Rank x2 = 0.426, P = 0.514). Conclusions Dissection of No 13 lymph node in D2 gastrectomy for gastric carcinoma is recommended in patients with poor-differentiation adenocarcinoma, mucous-cell cancer and signet-ring cell cancer, or when No 12 and No 14 lymph node metastasis is suspected.
4.Diagnostic Value of Image Findings of MRI and Discography for the Internal Disc Disruption.
The Journal of the Korean Orthopaedic Association 1997;32(3):497-505
In the investigation of patients with internal disc disruption, a discography has been the best method to decide whether intervertebral disc is normal or abnormal. Magnetic resonance imaging (MRI) of the spine is a new technique which offers an alternative method of obtaining this information. Some authors have reported MRI was more accurate than discography, but other reports have indicated discography was more useful test in symptomatic lumbar disc disease. The authors performed retrospective study to evaluate the diagnostic value of the image findings of MRI and discography in the internal disc disruption. Image findings of MRI and discography were analyzed comparing to pattern of provocative pain during discography. The concordant pain at discography was considered as a gold standard for evaluation of the diagnostic value of these modalities. The image findings of MRI and discography for 60 discs of 21 patients were graded and compared with the pain response at discography. The validity and predictive value (PV) of these modalities were calculated and the correlation between these image findings was evaluated. The sensitivities of discography and MRI were 83.3% and 90.9% respectively. The specificities of these findings were 47.1% and 46.7%. The positive PV of discography and MRI were 52.6% and 55.6%, and the negative PV were 80% and 87.5% respectively. There was no statistical significance in these discrepancies. The determinations of symptomatic disc level based on image findings are unreliable. The MRI can be considered as a screening test for internal disc disruption since it is non-invasive and sensitive diagnostic tool. The fusion level should be decided by the pain pattern at discography.

5.Anterior Cervical Fusion with Cervical Spine Locking Plate.
The Journal of the Korean Orthopaedic Association 1997;32(1):8-15
Anterior plate fixation of the cervical spine provides good primary stability to allow early mobilization without significant external support. Despite the obvious advantages of anterior cervical fixation, neurological injury resulting from the direct trauma of a drill bit or screw are possibile with this technique. In addition, screw loosening leading to dyphagia has been reported. The cervical spine locking plate (CSLP) system maintains the mechanical advantages of internal fixation and eliminate the neurological risks of perforating the posterior cortex. The purpose of this study is to review our experience with this device, to critically assess its ability to stabilize the cervical spine, and to assess for complications associated with this device. The authors reviewed 28 consecutive patients in whom the CSLP system was applied between April 1994 to April 1995. Average age was 44 years ranged from nineteen to seventy-two. Patients with trauma were eight and degenerative diseases were twenty. Eighteen screws were inserted in C3 bodies, twenty-four in C4, forty-one in C5, thirty-six in C6, twenty-four in C7, two in Tl and nine on grafted bone. With a mean follow-up of 15 months, 27 of 28 patients went on to fusion. Mean time to fusion was three months (range 2-5). Fusion status of one patient was considered as uncertain. Three patients had screws placed in the disc rather than in bone. One patient suffered deep wound infection, which developed to tracheoesophagial fistula. No patient showed neurological injury as a result of this device.

0.05),and the distribution of genotypes was in Hardy-Weinberg equilibrium.Data analysis showed Met326Ile variant did not impact on FIns,FPG,HOMA index,BMI and gene expression of PI3-K,though the expression of PI3-K gene was lower in type 2 diabetes than in control group.Conclusion The Met326Ile variant of the p85? regulatory subunit of PI3-K is likely to be functionally normal in type 2 diabetes and health people.

[Objective]To discuss the mechanism,diagnosis,and treatment of tumoral calcinosis,so as to improve the rate of diagnosis and cure.[Method]The diagnosis and cure course of 10 patients and the following visit were reviewed and analysed,at the same time the pathogeny,development,diagnosis,treatment and prognosis of TC were entirely analysed,combined with ancient literature.[Result]The symptom of pain disappeared with no recurring in all the patients followed up.[Conclusion]The focus of tumoral calcinosis which resemble tumour,always locate near to the great joint.Histopathological biopsy is necessary before operation.As curing,the focus must be excised absolutely,especially when the pedicel of the focus locate near to the bone,the nearby periosteum must be scraped,so as to avoid remnant and recuring.

While the scent of apple has no effect on learning and memory ability and hippocampal CREB and pCREB expression.

A set of specific primers was synthesized according to DNA sequence of HBV found in China, the reverse transcriptase (RT) region in polymerase gene was amplified by PCR method from the serum of 3 patients with chronic HBV infection, and then the PCR products were subcloned into pGEM Teasy vectors. 13 clones were sequenced. Sequence comparison of the selected clones was made to look for the difference. After being compared, 13 sequences of RT were found different. Besides 2 clones with long sequence deletion, the different rate of RT coding nucleic acid sequences, RT and HBsAg amino acid sequences of the 11 clones is 5 1%, 4 9% and 7 5%, respectively. Many mutation types, including point substitution and deletion mutation, were found in this region. There is quasispecies population and defective HBV genome in patients with chronic HBV infection.
