Epmedii Folium is a commonly used traditional Chinese drug, and is beneficial for the "liver" and "kidney" s function in Chinese medicine. Recently, the origin of this drug is more complex. Most of the identification studies are emphasized on the species certified by the pharmacopoeia and other related species from the same genus of Epimedium, but few was emphasized on the counterfeit. In this paper, one counterfeit of Epmedii Folium, identified as the dried leaf of Quercus variabilis (Fam. Fagaceae), has been reported based on field investigation, comparing specimen of Epmedii Folium and Q. variabilis,using the macroscopic, microscopic and TmC methods. It is resulted that they could be identified clearly not only by the macroscopic features, such as the vein character and the tooth apex, but also by the microscopic features, such as the vascular bundles of the midrib, the non-glandular hair, the anticlinal wall of the epidermis cell and the calcium oxalate crystal. Furthermore their TLC chromatograms showed also difference. This study will give reference for the identification of Epmedii Folium and the related supervision and inspection work.

To establish a cell model in vitro that stable expressing HBV by integrating HBA1.3 DNA into cell chromosome. The HBV1.3 full-length DNA was obtained by digested pGEM-HBV1.3 plasmid with HindIII and then was linked with PU-21 vector digested by HindIII. This was resulted in generation of a recombined plasmid named PU21-HBV plasmid. The recombined plasmid was introduced into HepG2 cells by electroporation. The transfected cells were screened with G418. The insertion and expression of HBV were identified by X-gal staining, RT-PCR and Southern blot. The result of PU21-HBV plasmid sequence demonstrated that HBV1.3 DNA was linked correctly with PU-21 vector. A series of positive cell colonies were obtained with G418 screening followed transfecting PU21-HBV plasmid into HepG2 cells. The results of Southern blot and RT-PCR exhibit that HBV1.3 DNA had successfully integrated into the chromosomes of HepG2 cells and had functional HBV gene transcription. HBV1.3 DNA was inserted into HepG2 genome and could stable transcript HBV RNA. The stable HBV expression cell line was constructed successfully. There are LoxP sites in the trapping vector PU21. With the Cre enzyme, interesting genes could be excganged into the LoxP sites. Therefore, double stable expression of interesting gene and HBV cell lines could be generated. The cell lines will be useful for further research some target gene function on replication of HBV.

Objective To investigate the effects of high spermatic vessel dissection on testicular morphological alteration of SD rats in prepuberty,puberty and sexual maturity phases.Methods Thirty-day-old SD rats were divided into 2 groups underwent sham operation and left high spermatic vessel dissection as a simulation of Palomo′s maneuver.Detailed morphological investigations were made at 3 different postoperative intervals among the 3rd day,30th day and 56th day.Results High spermatic vessel dissection in prepubertal rats induced acute testicular ischemia in the operated testes on the 3rd day.Most of the operated testes on the 30th day showed testicular atrophy.And all the operated testes showed testicular atrophy and sperm disappearance in epididymis on the 56th day.Conclusion High dissection of spermatic vessel in prepubertal rats induced testicular ischemia in prepuberty and testicular growth failure in puberty,testicular atrophy completely and sperm production losing in sexual maturity phase.

OBJECTIVETo ascertain the pathogen of aseptic encephalitis epidemic in Long-Yan city in Fujian, and to find out the genetic characteristics of the virus.

METHODSRapid detection of enteroviral RNA by reverse transcription polymerasechain reaction (RT-PCR) was directly carried out in cerebrospinal fluid(CSF) to isolate and identify the viruses from CSF at the same time, and to detect the neutralization antibody in two serum specimens collected in acute and convalescence phase. Nucleotides of VP1 region was also analyzed by constructing phylogenetic tree.

RESULTSECHO 19 infection was rapidly diagnosed and sequence analysed by RT-PCR, and then echovirus type 19 from 16 of 30 CSF samples (53.33%) was isolated and detected using RD and Hep-2 cells simultaneity. The titer of ECHO 19 neutralization antibody became positive or increased by 4 times from acute to convalescence phase in 4 of the 5 patients. Phylogenetic analyses of the VP1 genes of these isolates showed that their nucleotides identity were 98.9% -100.0% which were different from those ECHO 19 from GeneBank database by 13.0%-22.4%.

CONCLUSIONThe etiology of the epidemic of aseptic encephalitis was attributed to ECHO 19. The method of molecular identification not only provided rapid diagnosis of enterovirus infections, but also information about the genetic character of the viruses.

OBJECTIVETo study the role of the synchronized springy lengthening apparatus for the tibia and calcaneal tendon designed by the author in preventing the clubfoot of secondary to the Ilizarov tibia lengthening.

METHODSBased on the Ilizarov tibia lengthening apparatus, a special synchronized springy lengthening apparatus for the tibia and calcaneal tendon was designed. The tibial was made of distal and proximal 2 rings respectively and 4 threaded rods, and the calcaneal was made of a half ring, 2 hinges and a threaded rod with spring. The half ring was fixed to the calcaneus by 2 crossed wires. The fracture tibia and fibula, ankle joint, talocalcaneal joint were attached to the apparatus. At the same time of tibia lengthening, the soft tissue was simultaneously stretched, the ankle joint could move, and the leg could bear weight. If the clubfoot angle was larger, the percutaneous fasciotomy of calcaneal tendon was performed; if the angle was less than 20 degrees, the pes deformities were corrected only by the stretch of calcaneal tendon.

RESULTSSeventy-seven patients' tibia were lengthened averagely 4.6 cm, with an average speed of 0.7 mm/d. The healing made tibia lengthened, and the index was 1.35 months/cm. There were not the secondary varus and valgus deformities and clubfoot in all the patients. The clubfoot with 100-400 angle of the 16 patients were corrected after tibia lengthening.

CONCLUSIONSThe new apparatus coincides with the biomechanical principle and can effectively prevent the secondary deformities of foot such as clubfoot, talipes varus and valgus after tibia lengthening procedure.

OBJECTIVEThis study sought to analyze the clinical manifestations and intervention of fulminant septic shock in community-acquired Pseudomonas aeruginosa septicemia.

METHODSWe retrospectively reviewed the medical records for diagnosis, antibiotic therapy, clinical course of septic shock, respiratory support, laboratory data etc.

RESULTSEight of nine cases with P. aeruginosa septic shock died. Fever (nine cases) and cough (three cases) or diarrhea (3 cases) were the 2 most common initial symptoms, three cases developed skin gangrenosum later. Pseudomonas aeruginosa infection was not considered in any of the cases before death or blood culture showed positive result. Only 3 cases were initially treated with susceptible antibiotic regimen but no anti pseudomonas combination therapy was applied, susceptible antibiotic monotherapy was applied in 7 cases after transfer to the ICU. The mean latency of shock occurrence was 5.1 hours (range 0 to 21 hours) after admission, the mean duration from the occurrence of shock to death was 13.8 hours (range, 1 - 32 hours). All the patients were transfer red to ICU for shock, the appropriate resuscitation of shock patients was delayed by 49.3 minutes (range 25 - 80 minutes) by transfer. Only two cases were diagnosed and treated for shock on admission; after transferred to ICU, only 5 patients were diagnosed as having shock, and only 3 received anti-shock treatment. Eight of the patients died of persistent shock. In 6 patients who died, mechanical ventilation was not applied until cardiac arrest occurred. All the patients had hypoalbuminaemia, elevated serum C-reactive protein concentration, leukopenia and 6 cases had DIC.

CONCLUSIONThe initial presentation of the cases with community-acquired Pseudomonas aeruginosa septicemia was nonspecific with fever and cough or diarrhea. Clinicians often underestimated the severity of the infection, few patients received effective antimicrobial therapy. The authors suggest that an anti-pseudomonas antibiotic should be included in the initial empiric antibiotic regimen to cover P. aeruginosa high-risk patients; the front-line clinician should be educated for early recognition and aggressive resuscitation of P infection. aeruginosa septicemia.
