Objective To evaluate the diagnostic value of multi-slice spiral CT (MSCT)for traumatic spleen and liver rupture.Methods We made a retrospective analysis of 140 cases of liver and spleen injury with clinical manifestations confirmed by operation.MSCT examination results and clinical data were compared.Results Of the 140 cases,male patients outnumbered female ones,and the peak age was 10 - 30 years old.The injuries were most commonly attributed to traffic accident and falling.There were 69 (49%)cases of spleen injury,5 1 (36%) cases of liver injury,and 20 (14%)cases of both.Liver and spleen injuries showed on MSCT examination were liver and spleen laceration, hematoma within the liver and spleen as well as hematoma beneath the envelop. Conclusion MSCT has an important diagnostic value for traumatic liver and spleen rupture and thus can guide clinical treatment choice.

Recently traditional Chinese medicine (TCM)-induced liver injury has been an unresolved critical issue which impacts TCM clinical safety. The premise and key step to reduce or avoid drug-induced liver injury (DILI) is to identify the drug source of liver injury in early stage. Then the timely withdrawal of drug and treatment can be done. However, the current diagnosis of DILI is primarily governed by exclusive method relying on administering history supplied by patients and experience judgment from doctors, which lacks objective and reliable diagnostic indices. It is obvious that diagnosis of TCM-induced liver injury is especially difficult due to the complicated composition of TCM medication, as well the frequent combination of Chinese and Western drugs in clinic. In this paper, we proposed construction of research pattern and method for objective identification of TCM-related DILI based on translational toxicology, which utilizes clinical specimen to find specific biomarkers and characteristic blood-entering constituents, as well the clinical biochemistry and liver biopsy. With integration of diagnosis marker database, bibliographic database, medical record database and clinical specimen database, an integrative diagnosis database for TCM-related DILI can be established, which would make a transformation of clinical identification pattern for TCM-induced liver injury from subjective and exclusive to objective and index-supporting mode. This would be helpful to improve rational uses of TCM and promote sustainable development of TCM industry.

OBJECTIVETo observe the clinical effect of chronic fatigue syndrome (CFS) treated with moxibustion at Gaohuang (BL 43).

METHODSWith stratified block randomization, 72 patients accorded with inclusive criteria were divided into a moxibustion at Gaohuang (BL 43) group (moxibustion group) and an acupuncture group, 36 cases in each one. In the moxibustion group, Gaohuang (BL 43) was treated with big moxa cones as the main acupoint, 10 cones a time; Qihai (CV 6) and Zusanli (ST 36) were added with big moxa cones, 7 cones a time. In the acupuncture group, acupoints were the same as those in the moxibustion group, and twirling reinforcing method was used after qi arriving, 60 times one minute and 360° with range. In the two groups, 10-day treatment was made into one course and there were two days between courses. The treatment was given once a day for 3 courses. Changes of fatigue assessment index (FAI) before and after treatment and clinical effects were observed.

RESULTSThe total effective rate was 88.9% (32/36) in the moxibustion group, which was better than 72.2% (26/36) in the acupuncture group apparently (P < 0.05). After treatment in the two groups, FAI scores were obviously declined compared with those before treatment (both P < 0.01) and FAI score in the moxibustion group was apparently lower than that in the acupuncture group (P < 0.05).

CONCLUSIONMoxibustion at Gaohuang (BL 43) can improve the FAI score of patients with CFS and the clinical efficacy is definite.

ObjectiveTo investigate the haemostatic effect of combining pulsed therapeutic ultrasound (TUS) and microbubble (MB) on splenic trauma.MethodsForteen healthy dogs were divided into 3 groups.Six animals were treated by microbubble-enhanced therapeutic ultrasound (MEUS),the other eight animals were treated with TUS only ( n =4) and the MB only ( n =4) served aS the controls.The spleens of all animals were surgically exposed and a 20 mm long,5 mm deep incision was created on the spleens using scalpel.Human prothrombin complex (HPC) was slowly injected prior to the treatment.During the procedure,the initial bleeding rate and the bleeding rate after the treatment were calculated using gauze weighing.Contrast enhanced ultrasound (CEUS) was performed to assess the blocking effects of splenic circulation.The targeted spleens were harvested for pathological examination.ResultsThere were no differences in initial bleeding rate before treatment.After treatment,in the MEUS group oozed blood was found and the bleeding rate were lower than that of the TUS and the MB groups ( P ＜0.05).A nonenhanced or perfusion defect region was formed within the treated area.The histological results showed splenic sinus hyperemia,platelet aggregation and intravascular thrombosis.Conclusions Microbubbles enhanced pulsed therapeutic ultrasound can arrest the regional blood circulation of spleen by disrupting the microvasculature and this can be used in splenic heamostasis for treating spleen trauma.

Objective To investigate the effect of shRNA-mediated down-regulation of the receptor for activated C kinase 1 (RACK1) gene on the chemotherapeutic sensitivities in human lung adenocarcinoma cell line A549.Methods The shRNA recombinant plasmid targeting to human RACK1 gene was designed and transferred into A549 cells by lipofectin technique.The protein level of RACK1 was measured by Western blot to confirm the function of shRNA plasmid.Drug sensitivities of A549 cells to cisplatin,gemcitabine,pemetrexed and paclitaxel were analyzed by MTT assay.The protein expression of LRP and MRP were detected by Western blot.Results After 24 hours transfection,the relative expression quantity of RACK1 protein in RACK1-shRNA group was 0.267± 0.470,which was significantly lower than that in vector-shRNA group (0.821±0.109) and control group (0.842±0.060) (F =54.438,P ＜ 0.05).The results of MTT showed that the growth of A549 cells in the RACK1-shRNA group was markedly inhibited.The sensitivities of A549 cells to cisplatin and paclitaxel were significantly enhanced compared with that in the vector-shRNA group and control group (P ＜ 0.05).The relative expression quantity of LRP and MRP protein in RACK1-shRNA group were 0.163±0.056 and 0.246±0.050,which were lower than that in vector-shRNA group and control group (F LRP =19.430,F MRP =61.548,both P ＜ 0.05).Conclusion Targeted gene silencing of RACK1 improves the sensitivity of A549 cells to the ascisplatin and paclitaxel medicines,which might be achieved through down-regulation of the expression of LRP and MRP.

Objective:To purify HLA-DR molecules. Methods: Anti-HLA-DR antibody L243 was purified and coupled with CNBr activated Sepharose 4B gel. Immunoaffinity column was used to purify HLA-DR molecules. Results:Twenty micrograms of HLA-DR molecules were isolated from about 5 g Epstein-Barr virus-transformed human B lymphoblastoid cell line RAJI lysates by affinity chromatography. The purified HLA-DR molecules existed in α/β heterodimers form and could bind to conformation-dependent antibody L243. These HLA-DR molecules were separated into two strands,α and β,by boiling denaturation. These results are the basis for studying MHC Ⅱ binding peptide motif and CD4＋ T cell epitopes of antigens in future.
