ObjectiveTo explore the feasibility and safety of the spleen-preserving surgery in the treatment of traumatic rupture.Methods47 patients with traumatic rupture were treated with spleen-preserving surgery:the biological glue which local physical bleeding had 7 cases,suture repair had 13 cases,splenic artery ligation had 10 cases,splenic artery ligation and splenic repair had 9 cases,partial splenectomy had 8 cases.Results47 patients had four cases of infection,and cured after dressing,1 case had postoperative bleeding symptoms and used splenectomy surgery.46 patients with spleen-preserving operation is successful,the average length of stay was 15 days,there is no deaths.After 6 months,all patients used abdominal B-utrasoundor CT scans to confirm the survival of spleen is good and indicator of the examination is normal.Follow-up of these patients had no dangerous infections and complications.ConclusionSpleen-preserving surgery in the treatment of traumatic rupture was safe,feasible,could retain the greatest degree of function,and could be used in clinical practice.

Besides 36 (28 single-tablets and 8 fixed-dose combinations) used antiretroviral drugs clinically, there are a number of investigational antiretroviral agents currently in phase 2-3 clinical trial. Tenofoviralafenamidefumarate (TAF) is a novel nucleoside analogue reverse transcriptase inhibitor that is potent and less toxicity than tenofovir (TDF). Doravirine is a non-nucleoside analogue reverse transcriptase inhibitor that demonstrates activity against NNRTI-resistant viral strains. GSK744 is an integrase inhibitor with a long acting preparation. In addition, several drugs with new mechanisms are also noted, for example, BMS-663 068 is a small molecule CD4 attachment inhibitors and cenicriviroc is a novel CCR5/CCR2 antagonist with antiretroviral activity and anti-inflammatory effects. Several drug classes that target known pathways in HIV latency have being developed, and leading the list are histone deacetylase inhibitors. Other agents include protein kinase C activators, positive transcription elongation factor activators, DNA methyl-transferase inhibitors and histone methyl-transferase inhibitors and so on. This review is focused on the above-mentioned drug candidates that may be used in clinical in next couple of years and those compounds that can reverse latent HIV infections.

Objective To investigate the effects of electroacupuncture at Neiguan point (PC6) and Jianshi point (PC5) combined with granisetron on chemotherapy-induced nausea and vomiting. Methods Seventy-two tumor patients undergoing chemotherapy were randomly divided into an electroacupuncture group (38 patients) and a false electroacupuncture group (34 patients). The electroacupuncture group received electroacupuncture at PC6 and PC5 (1 h, bid) combined with granisetron (3 mg, i.v.) 30 min before chemotherapy, and repeat one time after 12 h. The false electroacupuncture group received electroacupunctur at false PC6 and false PC5, and other treatment same as the electroacupuncture group. Both groups were treated for 3 days. The nausea and vomiting frequencies and clinical effects were compared between the two groups. Results The vomiting frequency in the electroacupuncture group was significantly lower than that in the false electroacupuncture group on day 2 (0.37 ± 0.75 vs. 1.12 ± 2.13;t=2.034, P=0.046). The nausea degree in the electroacupuncture group was significantly lower than that in the false electroacupuncture group on day 2 (1.21 ± 0.93 vs. 1.88 ± 0.59;t=3.596, P=0.001) and day 3 (1.26 ± 0.92 vs. 1.68 ± 0.53; t=2.293, P=0.025). The total effective rate in the electroacupuncture group was significantly higher than those in the false electroacupuncture group on day 2 (76.3% vs. 64.7%; χ2=12.390, P=0.006) and day 3 (73.7%vs. 64.7%;χ2=12.313, P=0.006). Conclusions Electroacupuncture at PC6 and PC5 combined with granisetron can attenuate chemotherapy-induced nausea and vomiting.

The Auditory Apperception Measurement Model (AAMM) is often used to test the ability of people's auditory learning. Through learning auditory signals,the testees' apperception abilities are tested under different process of learning. In this paper,the AAMM is built,and the design and realization of the software is introduced.

Objective To investigate the effects of adiponectin on cell activity and expression of T-cadherin in human retinal pigment epithelial(hRPE) cells cultured with high glucose.Methods ①The hRPE cells were divided into three groups:normal glucose group(5.5mmol/L glucose),high glucose group (33mmol/L glucose),high glucose plus adiponectin group (33mmol/L glucose+2.5ug/ml adiponectin).48h later,the cell activity was observed by MTT assay.②After the above groups were cultured respectively for 24h,48h,72h again,the expression of T-cadherin mRNA was observed by RT-PCR. Results ①Cell activity in high glucose group significantly decreased. Cell activity adiponectin group was higher than that in the high glucose group.②With the extension of time ,the expression of T-cadherin decreased in high glucose group,but increased in adiponectin group. Conclusion Adiponectin may be protect the hRPE cells by T-cadherin.

OBJECTIVE： To investigate the possible role of the alteration of mitochondrial transmembrane potentials(Δ Ψ m) in arsenic trioxide(As2O3)-induced apoptosis of human gastric adenocarcinoma cells(SGC7901).METHODS： Cell apoptosis was assessed through morphology， cell viability， the percentage of sub-G1 cells and phosphatidylserine(PS) externalization.the Δ Ψ m was detected on flow cytometry through double staining of Rhodamine 123 (Rh123) and propidium iodide(PI).RESULTS： The As2O3-induced apoptosis was associated closely with the disruption of the Δ Ψ m.CONCLUSION： The disruption of the Δ Ψ m is one of the mechanisms of As2O3-induced apoptosis.

Objective The aim of the study was to determine the diagnostic value of color Doppler ultrasound in the assessment of the breast mass.Methods The results of ultrasonograph of the breast mass were retrospectively observed in 79 operation and pathological proven breast mass parients,in which 47 patients had proven malignant breast mass and 32 patients had proven benign malignant breast mass.Results Color Doppler ultrasound had a sensitivity of 100%for diagnosing breast mass,accuracy of 93.7%(30/32)and 91.4%(43/47)for diagnosing malignant and benign mass.Conclusion Color Doppler ultrasound has high diagnostie value in distinguishing malignant from benign mass.
