Objective To observe the curative effects and toxicity of low-dose bortezomib plus thalidomide and chemotherapy in treatment of multiple myeloma. Methods 35 patients with initial, refractory or relapsed MM received at least two cycles of treatment with bortezomib at 1.1 mg/m2 intravenously on days 0,3, 7, and 10, and by daily oral thalidomide escalated from 50mg to 150 mg and chemotherapy. The chemotherapy regimens included MP, VAD and AD regimen which was chosen according to the status of patients. Results After a median follow-up of 20 months, the overall response rate was 82.8 %, complete remission (CR)48.6 %, very good partial remission (VEPR) 17.1%, and partial remission 17.1%. The 3-year PFS and OS were 60.92 % and 72.41% separately. ORR and OS were same in initial and refractory or relapsed MM patients. Grade 3 or 4 adverse events including debility (3/35), nausing and vomiting (8/35), constipation (4/35), peripheral sensory neuropathy (3/35), neutropenia (10/35) and thrombocytopenia (12 %) were observed.Conclusion The regimen of low-dose bortezomib plus thalidomide and chemotherapy is a highly effective and safety regimen for MM patients. The maintenane therapy with thalidomide may prolong PFS.

OBJECTIVE:To analyze the rules and characteristics of adverse drug reactions(ADR)induced by Shuxuetong in-jection,and provide reference for clinical rational drug use. METHODS:ADR cases induced by Shuxuetong injection in Beijing collected by national ADR monitoring center in 2012 were retrieved,and 35 cases of the ADR were statistically analyzed. RE-SULTS:ADR induced by Shuxuetong injection had relatively high incidence in elder over 60 years old(68.57%);ADR might oc-curred after 5 min with off-label use and it mainly occured after 10 min-2 h(40.00%);clinical manifestations were mainly systemic damage and nervous system damage,and all patients were returned to normal after symptomatic treatment except one with unclear outcome. CONCLUSIONS:ADR induced by Shuxuetong injection is related to age and dosage. Clinical medication should be strict-ly in accordance with the instructions,strengthen medication monitoring and reduce incidence of ADR to ensure medication safety.

Mycotic vaginitis is a common and frequently-occurring gynaecopathia and easy to attack repeatedly, so painful to patients. In this study, the authors observed the clinical efficacy of Sophora gel combined with Fluconazole capsules in treating mycotic vaginitis, in order to seek an effective method for treating mycotic vaginitis. Totally 85 patients with mycotic vaginitis treated in our hospital between December 2012 and July 2014 were randomly divided into the treatment group (43 patients) and the control group (42 patients). The treatment group was given vaginally Sophora gel (one piece every night for 14 days) and orally Fluconazole capsules (150 mg, once every three days, four times in total); The control group was only administered with Fluconazole capsules. The total efficacy, cure rate, recurrence rate and clinical symptom improvements of the two groups were observed. The results show that the total efficacy, the cure rate and the recurrence rate of the treatment group vs. the control group were respectively 97.7%, 90.7% and 2.6% vs. 83.3%, 71.4% and 20.0%, with statistical significance in their differences (P < 0.05). The treatment group showed reduced leucorrhea, pruritus vulvae disappearance and earlier mucosal hyperemia disappearance than the control group, with statistical significance in their differences (P < 0.05). In conclusion Sophora gel combined with Fluconazole capsules can improve antifungal activity of drugs, relieve clinical symptoms, shorten the course of disease, enhance the cure rate and reduce the recurrence rate; So this therapy can be widely applied in clinic.

T cell immune receptor with Ig and ITIM domains (TIGIT), a promising new target in cancer immunotherapy, plays a critical role in limiting adaptive and innate immunity against tumors. The extracellular domain of human TIGIT was used to immune BALB/c mice, and a new anti-human TIGIT chimeric antibody (c7D3) was developed. The mice in this study were used in accordance with the international guidelines for the care and use of laboratory animals, and the animal study was approved by the Institutional Animal Ethics Committee of AbMax Biotechnology. The biological activity of c7D3 was studied. The results showed that c7D3 exhibited high affinity for TIGIT and effectively inhibited the interaction between TIGIT and its ligands. Cell-based assays indicated that c7D3 induced strong luciferase signaling in TIGIT/CD155 signaling reporter assay and enhanced cytokine secretion in a T cell stimulation assay. The data showed that c7D3 has high binding affinity and excellent blocking bioactivity, supporting the further advancement for therapeutic application.

Objective To study the clinical characteristics of neonates with Listeriosis sepsis and explore the nursing experience. Methods The clinical data of 22 cases with neonatal Listeriosis sepsis were retrospectively analyzed.Results Twenty-two neonates developed Listeria monocytogenes sepsis 0.5 h~5 d after birth with 13 cases of low birth weight. The stay was 2~77 d,10 were discharged after recovery,7 were discharged after signature of their families due to improvements and 5 died of meningitis and septicemia.Conclusion Timely and accurate collection of samples should be done for laboratory examinations.Close observation of the diseases,attaching importance to infant feeding and implementation of infant developmental nursing are all critical for the improvement of cure rate.

Objective To observe the expression of hypoxia inducible faetor-1α (HIF-1α) in the retina of rabbits with acute high intraocular pressure and to investigate the mechanism of systemic domestic recombinant human erythropoietin (rhEPO) protecting the retina from ischemia-reperfusion injury. Methods First, control group and model group were established in rabbit eyes. The acute high intraocular pressure model was established by saline perfusion into anterior chamber, and then hypodermic injection of domestic rhEPO was made. HIF-1α protein in the retina was observed by immunohistochemical staining method on days 1, 3, 7 and 14 after retinal ischemla-reperfusion, respectively. Results No cells with HIF-la positive expression were observed in the retina of the control group. Ceils with HIF-1α positive expression in the model group outnumbered those in the control group (P < 0. 01). The resemblance pattern occurred in EPO group but its degree was slightly greater than that in the model group from day 3 after ischemia-reperfusion (P<0.05). Conclusion Domestic rhEPO can down-regulate the expression of HIF-1α in the retina with acute high intraocular pressure, which may be one of the mechanisms that rhEPO protects the retina from ischemia-reperfusion injury.

OBJECTIVE:To study the effects of 10 kinds of nephrotoxic TCM on three main subtypes(Oat1,Oat2 and Oat3) of kidney organic anion transporter(Oats)in mice. METHODS:A total of 1 840 SPF NIH mice were randomly divided into nor-mal control group(isovolumic pure water),probenecid group(30 kg/mg),sodium carboxymethyl cellulose(CMC)group,Pulsa-tillae radix,Corydalis rhizoma,Aconiti kusnezoffii radix,Aconiti radix,Angelicae pubescentis radix,Gleditsiae spina,Polygo-num cuspidatum,Kansui radix,Platycladi cacumen,Aucklandiae radix high and low dose groups. Mice were treated twice a day for 5 d,ig. After 1 h of the last dosing,they were iv given PAH in tail(30 mg/kg). The PAH pharmacokinetic parameters of the kidney homogenate were determined and the PAH intake in kidney tissue at the time point of 1,5,10,15 and 20 min was detect-ed. The PAH in blood was analyzed by DAS 2.0 software. The grouping and dosing were the same as before,after 1 h of the last dosing,kidney slices were made and put into PAH-buffer. The PAH intake of kidney slices was determined. RESULTS:Compared with normal control group,the t1/2β in C. rhizoma high dose group,A. kusnezoffii high and low dose groups,A. pubescentis high dose group,P. cuspidatum high and low dose groups and P. cacumen group were increased;Vd were all decreased in 10 kinds of TCM high and low dose groups;except for A. pubescentis low dose group,G. spian low dose group and K. radix low dose group, the CL was decreased and AUC0-20 min was increased in all other groups,with significant difference (P<0.01 or P<0.05). Com-pared with normal control group,the content of PAH in kidney tissue in P. radix high dose group,C. rhizoma high dose group,A. kusnezoffii high dose group,A. radix high and low dose groups,A. pubescentis high and low dose groups,G. spina high and low dose groups,P. cuspidatum high and low dose groups,K. radix high and low dose groups,P. cacumen high and low dose groups and A. radix high and low dose groups were increased,with significant difference (P<0.01 or P<0.05). Compared with normal control group,the intake of PAH in kidney slices in C. rhizoma high dose group,A. kusnezoffii high and low dose groups,G. spi-na high and low dose groups,K. radix high dose group,P. ca-cumen high and low dose groups and A. radix high dose group were decreased,with significant difference (P<0.01 or P<0.05). CONCLUSIONS:The 10 kinds of nephrotoxic TCM probably induced kidney injury through inhibiting the Oat1,Oat2 and Oat3 of Oats.

OBJECTIVE To investigate the effect of Radix Isatidis and its constituents indigo and in?dirubin on two principal subtypes of organic cation transporters(OCT)OCT1,OCT2 in vivo in mice. METHODS Decoction of Radix Isatidis (DRI) 1.6 and 6.4 g · kg-1,granules of Radix Isatidis (GRI) 0.615 and 2.460 g·kg-1,indigo 0.008 and 0.640 mg·kg-1 and indirubin 0.0192 and 1.536 mg·kg-1 were ig given to NIH mice(60 mice per group),twice a day for 5 d. Four control groups were set up,including the vehicle of water,0.5% sodium carboxymethyl cellulose(CMC),additives of sucrose plus dextrin (1.5 g · kg-1)and positive control quinidine(0.025 g · kg-1). Sixty minutes after the last dosing,all the mice were iv given metformin(Met)5 mg·kg-1,and at 1.0,2.5,5.0,7.5,10.0 and 20.0 min after Met iv,10 mice in each group were sacrificed to collect whole blood and kidneys respectively. The right kidney was homogenized for Met accumulation test and the left one used to extract total RNA for analysis of OCT1 and OCT2 mRNA expressions by real-time PCR. The contents of Met in sera and kidneys were quantified by HPLC. Major pharmacokinetic parameters of Met in sera were analyzed by pharmacokinetic software(DAS 2.0). RESULTS There was no significant difference between water control group,0.5%CMC group and sucrose plus dextrin group in any examined item. Compared with vehicle control group (water and 0.5%CMC group),all the related pharmacokinetic parameters in DRI 6.4 g · kg- 1,GRI 2.46 g · kg-1,indigo 0.640 mg · kg-1 and indirubin 1.536 mg · kg-1 groups were changed significantly (P<0.05,P<0.01). The elimination half time (t1/2β) was prolonged 13%-97%,volume of distribution reduced by 13%-72%,clearance(Cl)reduced by 9%-65%,and the area under the concentration-time curve (AUC0-20 min) increased by 13%-135%. AUC0-20 min obtained from renal Met accumulations was significantly increased(P<0.01)while Met uptake by kidney slices was reduced(P<0.05,P<0.01). The expressions of OCT1 and OCT2 mRNA were obviously down-regulated(P<0.05,P<0.01). CONCLUSION The mouse renal OCT1 and OCT2 are significantly inhibited by DRI,GRI,indigo and indirubin. The inhibitory effect of Radix Isatidis on OCT1 and OCT2 probably arises from indigo and indirubin contained.
