ObjectiveTo evaluate the effect of different operative methods for treating rebleeding in patients with portal hypertension(PHT). MethodsThe clinical data of 66 patients with postoperative ebleeding out of 373 PHT cases during the last 30 years was retrospectively analyzed. Their first operations were splenectomy, portoazygous devascularization, various non-selective shunt and combined operation(devascularization combined with shunt), of which, the rebleeding rate were 26.67 %, 17.86 %, 14.58 % and 4.35 %, respectively. Among 55 cases receiving re-operation, there were 42 with distal esophago-fundusectomy, 11 mesocaval shunt(MCS)and 2 re-devascularization. The other 11 cases received nonoperative therapy. ResultsThe mortality, mean follow-up time, rebleeding rate and encephalopathy rate were 9.52% (4/42), 11 years,9.52% (4/42)and 14.29% (6/42)in distal esophago-fundusectomy group;0,7.5 years,0 and 9.09% (1/11)in MCS group. All 2 cases in re-devascularization group died within one postoperative month. All 11 cases in non-operative group were with portal hypertension gastropathy(PHG). ConelusionCombined operation may effectively reduce postoperative rebleeding rate in PHT cases and MCS is a relatively ideal method for treating rebleeding.

Orthopedic Journal of China 2006;0(12):-
[Objective]To study the effect of intra-operative three-dimensional fluoroscopy-based spinal navigation guidance for vertebroplasty to treat osteoporotic vertebral compression fracture(OVCF).[Method]A clinical study was performed in which 41 patients suffering painful osteoporotic vertebral compression fractures underwent vertebroplasty procedure.During this procedure,cannulation of the pedicle and vertebral body was performed with the aid of isocentric 3D fluoroscopy-based spinal navigation(group A) and biplanar fluoroscopy(group B).RDQ and VAS of each group was compared between preoperation and postoperation.Total operating time,intra-operative fluoroscopy time and pedicle puncturation accuracy were compared between group A and group B.Possible complications such as cement extravasations were evaluated with X-ray fluoroscopy.[Result]Forty-six vertebrae were successfully injected with polymethyl methacrylate.The two groups had statistically significant difference in RDQ and VAS between preoperation and postoperation,but no statistically significant difference between the two groups.Mean operating time and intra-operative fluoroscopy times of group A were shorter than those in group B.There was no case of broken pedicle in group A.One vertebra was found to have bone cement leakage to soft tissue in group B,but the vertebral canal and pedicle intact.The author followed up for an average of 21 months(range 8~38 months) and found no severe complication or collapse of vertebra.[Conclusion]With the aid of intra-operative three-dimensional fluoroscopy-based spinal navigation,vertebroplasty can be performed more accuractly and securely.The shorter total operating time,intra-operative fluoroscopy times are convincing and less possible complication can be expected.

To obtain the key genes for chlorogenic acid biosynthesis of Lonicera hypoglauca, four new genes ware obtained from the our dataset of L. hypoglauca. And we also predicted the structure and function of LHPAL4, LHHCT1 , LHHCT2 and LHHCT3 proteins. The phylogenetic tree showed that LHPAL4 was closely related with LHPAL1, LHHCT1 was closely related with LHHCT3, LHHCT2 clustered into a single group. By Real-time PCR to detect the gene expressed level in different organs of L. hypoglauca, we found that the transcripted level of LHPAL4, LHHCT1 and LHHCT3 was the highest in defeat flowers, and the transcripted level of LHHCT2 was the highest in leaves. These result provided a basis to further analysis the mechanism of active ingredients in different organs, as well as the element for in vitro biosynthesis of active ingredients.

Objective To summarize the clinical presentation, pathology features, and treat-ment principle for primary testicular non-Hodgkin's lymphoma. Methods Twelve patients were di-agnosed with primary testicular lymphoma. The mean age was 62 years (36-78). Of the patients, unilateral primary testicular tumors were found in 11 cases and bilateral tumors were found in 1 case. All cases had swollen testes, 3 cases had mild pain and 1 had low-grade fever. Ultrasonic examination detected solid mass in all 12 cases. CT scan revealed retroperitoneal enlarged lymph nodes in 3 cases. Nine patients were diagnosed with disease of stage Ⅰ E, 2 of stage Ⅱ E, and 1 of stage Ⅲ E. All of the patients underwent radical orchiectomies. Postoperative treatment included: CHOP chemotherapy for 10 cases, radiotherapy after chemotherapy for 5 cases, and surgery alone for 2 cases. Results Post-operative pathology results were non-Hodgkin's lymphoma in all cases. One patient lost in follow up, one died within 2 years because of other disease. The 1, 3 and 5 year actual survival rates were 82% (9/11) ,40%(4/10),20% (2/10), respectively. The relapsed organs included contralateral testis(3/ 11), central nervous system(3/11), liver(1/11)and retroperitoneal lymph node(1/11). Conclusions The prognosis of the primary testicular non-Hodgkin's lymphoma is very poor. Chemotherapy must be used after surgery for any stage. Stage Ⅰ E and Ⅱ E patient should be treated by surgery combined with radiotherapy and chemotherapy. Contralateral testis should be irradiated prophylactically. Pa-tients beyond stage Ⅱ E should accept chemotherapy after surgery and radiotherapy according to the patient's status.
