Objective To investigate the clinical characteristics,management and prognosis of choriocarcinorna in postmenopausal women. Methods Six cases of choriocarcinoma in postmenopausal women were reviewed retrospectively. Results Four cases in the 6 patients presented with abnormal vaginal bleeding. All of the six cases received chemotherapy and four cases underwent hysterectomy. Three cases achieved complete remission,one partial remission,one stable condition,and one disease progression.One case died,two cases lost follow-up and three cases survived as follow-up so far. Conclusion The diagnosis of pregnancy-related disease should be considered in the elderly women presenting with abnormal vaginal bleeding.Once diagnosed,chemotherapy should be given as soon as possible. Satisfactory effects can be achieved with a combination therapy of chemotherapy and surgery.

Primary testicular lymphoma (PTL) is an uncommon extranodal lymphoma,with an aggressive clinical course and poor outcome.A combined treatment with full-course anthracycline-based chemotherapy with rituximab and central nervous system prophylaxis with intrathechal methotrexate and contralateral testicular radiotherapy should be considered as the standard of care at limited stage.These patients have a very high risk of central nervous system recurrence and the addition of systemic central nervous system prophylaxis with intravenous methotrexate may be the best treatment option.Primary central nervous system lymphoma (PCNSL) is an aggressive disease with a dismal prognosis,particularly when treated with established protocols used for systemic non-Hodgkin lymphoma.Use of methotrexate in combination with cytarabine has been proposed as a standard induction regimen.The role of the anti-CD20 antibody has not yet been defined,however,phase Ⅰ and Ⅱ trials suggest its efficacy despite low penetration within the cerebrospinal fluid.High-dose chemotherapy followed by autologous stem cell transplantation has shown high remission rates with 3-year overall suvival rates of up to 87 ％.

Primary mediastinal large B-cell lymphoma (PMBCL) is a unique type of B-cell lymphoma probably arising from a putative thymic medulla B cell.It constitutes 6 ％-10 ％ of all diffuse large B-cell lymphomas (DLBCL),with special pathologic features,immunophenotype and genetic abnormlities,and need to be identified with classical Hodgkin lymphoma and other types of DLBCL.In this review,the pathological features,molecular biological changes,treatment,prognosis and treatment of PET in the evaluation of the initial reaction in PMBCL were summarized.

Objective To observe and analyze the oral and maxillofacial appearance of patients with acquired immune deficiency syndrome(AIDS)and to explore the effective detection methods of hunman immunodeficiency virus(HIV)infection,aimed at early diagnosis of HIV infection and AIDS,providing reference for treatment and prevention.Methods 21 6 cases of suspected HIV infec-tion and AIDS therapy-naive patients in the department of infection disease in this hospital,from January 2012 to March 2014,were selected.Oral and maxillofacial appearances,detection methods and its results were retrospectively analysed.Results The main clinical manifestations of patients with HIV infection and AIDS were oral candidiasis,oral hairy leukoplakia,herpes simplex virus infection,Kaposi′s sarcoma,periodontal disease,ulcer disease and other abnormal attribute.All of the 21 6 samples were positive in the preliminary screening,214 cases were confirmed by western blotting(WB),and the sensitivity,specificity and false positive rate were 99.07%,100.00% and 0.926%,repectively.Conclusion Focusing on clinical symptoms and signs in oral and maxillofacial re-gion of patients with HIV infection and AIDS could provide significant references for clinical diagnosis,and combing detection meth-ods of enzyme linked immunosorbent assay(ELISA)and WB could make a definite diagnosis,which might be benefit to make effec-tive prevention and treatment measures and in order to control the infection and improve the prognosis.

Four cellulolytic strains, which can be used as feed additive, were studied under the conditions of various temperature, incubation time, and anaerobic process, and examined the changes of their cell protein content, cellulase and hemi-cellulase activity. The results show: 1) The maximum cellulolytic enzyme activities were observed incubation 20h; 2) Constant medium temperature 28℃ was adequate to the growth of the 4 strains ; 3) anaerobic condition, 39℃±2℃ and fermentation 12h, 24h, 36h, the tested strains can growth well in PDA plate, however, the cellulolytic enzyme activities and growth of the tested strains were influenced adversely when fermentation 48h. The experiment provide many important basis for the strains production, storage and utilization.

One hundred and sixty non-diabetic patients with cerebral ischemia of primary onset were enrolled in the study. The patients were divided into impaired glucose tolerance (IGT) group and normal glucose tolerance (NGT) group according to the oral glucose tolerance test (OGTT). Carotid atherosclerosis and carotid artery stenosis were examined with vascular Doppler ultrasonic detection. The incidence rates of carotid atherosclerosis in IGT group and NGT group were 87. 5% (70/80)and 63.8% (51/80)respectively (χ2= 12.240,P <0.001);the incidence rates of carotid stenosis in IGT group and NGT group were 63.8% (51/80) and 47. 5 % (38/80), respectively(χ2 =4. 279, P =0. 039);the degree of carotid artery stenosis in IGT group was higher than that in NGT group(χ2= 21.95, P < 0. 01). The results indicate that IGT may be related to atherosclerosis and stenosis of carotid artery in cerebral ischemic patients.

Objective To evaluate the effect of total glucosides of paeony (TGP) on the expression of interleukin-18 (IL-18) in human HaCaT keratinocytes,and to explore the roles of extracelluar signal-regulated protein kinase1/2 (ERK1/2) and c-Jun N-terminal kinase 1/2 (JNK1/2) signaling pathways in the effect.Methods Some cultured human HaCaT keratinocytes were classified into three groups:control group treated with dimethyl sulfoxide (0.031％),TGP groups treated with 6 different concentrations (0.5,2.5,12.5,62.5,125.0 and 312.5 mg/L) of TGP respectively,inhibitor groups treated with TGP of 125 mg/L after 2-hour pretreatment with PD98059 (an ERK1/2 inhibitor) and SP600125 (a JNK1/2 inhibitor) of 10 μmol/L respectively.After additional culture for 48 hours,reverse transcription (RT)-PCR was performed to measure the mRNA expression level of IL-18,and enzymelinked immunosorbent assay (ELISA) to determine the level of IL-18 protein in the culture supematant of HaCaT cells.Some HaCaT keratinocytes were classified into two groups to be treated with TGP of 125 mg/L for 15,30 and 60 minutes with or without the pretreatment with PD98059 and SP600125 of 10 μmol/L; then,Western blot was carried out to determine the phosphorylation levels of ERK1/2 and JNK1/2 in HaCaT cells.Results The levels of IL-18 mRNA and protein in culture supernatant were significantly increased by TGP of 0.5 and 2.5 mg/L,but decreased by TGP of 62.5 and 125.0 mg/L,and TGP of 125.0 mg/L showed the strongest inhibitory effect.After treatment with TGP of 125.0 mg/L,the level of phosphorylated ERK1/2 in HaCaT cells peaked at 15 minutes (0.448 ± 0.018),decreased to 0.213 ± 0.005 at 30 minutes and 0.217 ± 0.005 at 60 minutes,with significant differences between TGP-treated and untreated cells at 15 minutes (0.448 ± 0.018 vs.0.204 ± 0.005,P＜ 0.05) but not at 30 or 60 minutes (both P ＞ 0.05).The phosphorylation level of ERK1/2 was 0.237 ± 0.010 in HaCaT cells pretreated with PD98059 prior to the treatment with TGP,significantly different from that in HaCaT cells treated with TGP only (P ＜0.01).TGP of 125.0 mg/L had no obvious effect on JNK phosphorylation,and there was no significant difference in the level of phosphorylated JNK1/2 between HaCaT cells untreated and those treated with TGP of 125.0 mg/L for different durations (all P ＞ 0.05).Conclusions TGP can inhibit the expression of IL-18 mRNA and protein in HaCaT cells,likely through the ERK1/2 signaling pathway.

Objective To explore the effect of health education path on rehabilitation training of patients with total knee arthroplasty (TKA).Methods One hundred and eighty TKA patients were divided into experiment group and control group equally according to the sequence of admission.In the control group routine rehabilitation training was adopted,while in the experiment group the training was done on the instruction of health education path.The two groups were compared in terms of training accuracy,scores on health education, satisfaction with nursing and training efficiency after 12 months.Result Training accuracy,scores on health education,satisfaction with nursing and training efficiency after 12 months of the experiment group were significantly higher than those of control group(all P<0.05).Conclusion The application of health education path in rehabilitation training of TKA patients can improve the training efficiency and is good for patients’recovery.

OBJECTIVE:To study the pharmacokinetics and the bioequivalence of mycophenolate mofetil(MMF)dry suspension versus its imported tablets counterpart in healthy volunteers.METHODS:In a randomized two period crossover study,each of the 20 healthy male volunteers received a single oral dose of 0.75 mg dry suspension or imported tablet of MMF.The plasma concentration of mycophenolic acid(MPA),which is the active metabolite of MMF,were determined by HPLC.The pharmacokinetics of MPA were estimated by the non-compartment model and the bioequivalence of the two formulations of MMF were evaluated by ANOVA and two one-sided-test.RESULTS:The main pharmacokinetic parameters of MMF dry suspension versus imported MMF tablet were as follows:t1/2? were(16.80?4.10)and(16.77?4.50)h;tmax were(0.4?0.1)and(0.7?0.4)h;Cmax were(19.29?6.78)and(18.22?7.19)?g?mL-1;AUC0～72 were(39.22?10.43)and(39.38?10.46)?g?h?mL-1,and AUC0～∞ were(40.58?10.49)and(41.00?10.88)?g?h ?mL-1 respectively.The relative bioavailability of the test preparation(dry suspension of MMF)was(100.9?10.6)%.CONCLUSION:The two formulations are bioequivalent in healthy volunteers.

BACKGROUND:Intensity-time (I/T) curve examination is a monitoring technology used for diagnosis of nerve damage,muscle disease and prognostic evaluation using current stimulation and qualitative or quantitative analysis.It also has significance to the diagnosis of lumbar disc herniation (LDH).Whether it can be used in LDH prognostic evaluation is poorly understood.OBJECTIVE:To explore the effectiveness of I/T curve in diagnosis and prognostic evaluation of LDH.METHODS:I/T curves of 113 LDH patients were measured by CX-3 electrodiagnostic equipment,and the results were compared with their unaffected sides and analyzed after physiotherapy.A total of 253 curves were measured,including 107 biceps femoris,101 gastrocnemius and 45 tibialis anterior muscle curves.All patients were sequential treated by traction,medium frequency,ultrashort wave,electric acupuncture as well as infrared radiation following I/T diagnosis,once a day,10 days for a course,with 10 days interval in 3 courses,I/T curves were performed after 3 courses.The therapeutic effect was evaluated by using I/T results combined with clinical symptom and physical signs.RESULTS AND CONCLUSION:The first estimated percentage by I/T curved line were 36.36% (controlled by normal nerve),62.85% (controlled by part of the denervated),0.79% (controlled by the completely denervated) and 63.64% (controlled by total abnormal nerve).After the physiotherapy,the effectiveness of the complete recovery was 92.86% by the normal nerve as well as 58.82% by the abnormal nerve.Above all,the practical value could be concluded from the diagnosis,evaluation and effectiveness of LDH used by I/T curve line.The therapeutic effectiveness controlled by the normal nerve is much better than that controlled by the abnormal.
