Objective To investigate of the clinical effects of the combined use of all-trans retinoic acid compound and capsule of total glucosideof paeony on reticular oral lichen planus.Methods A total of 120 patients were randomly divided into 3 groups:experimental group (group E),control group 1 (group C1),and control group 2 (group C2).Topical application of alltrans-tretioin compound and systematic administration of capsule of total glucosides of paeony were applied in group E.The group C1 only received topical application of alltrans-tretioin compound and the group C2 only took oral administration of capsule of total glucosides of paeony.The clinical effects were evaluated 3 months and 6 months after application of these medicines.The clinical results were followed up for 6 months.Results A total of 107 patients completed the follow-up.The total effective rates were 78％ (29/37),75％ (27/36) and 56％ (19/34) in group E,C1,and C2 respectively after the administrations for 3 months.There was significant difference between group E and group C2 (x2 =4.094,P =0.043).No significant difference between group E and group C1 was found (x2 =0.117,P =0.733).After 6 months,the total effective rate of group E(86％) was significantly higher than that of group C1 (64％) (x2 =4.303,P =0.038) or C2 (62％) (x2 =5.722,P =0.017).Conclusions The combined application of topical all-trans retinoic acid compound and capsule of total glucosideof paeony could improve the clinical symptoms of reticular oral lichen planus.

OBJECTIVETo apply an orthogonal design optimization strategy to a mouse model of acute liver failure induced by D-galactosamine (D-GalN) and lipopolysaccharide (LPS) exposure.

METHODSA four-level orthogonal array design (L16(45)) was constructed to test factors with potential impact on successful establishment of the model (D-GalN and LPS dosages, and dilution rate of the D-GalN/LPS mixture). The mortality rate of mice within 24 hours of D-GalN/LPS administration was determined by the Kaplan-Meier method. The model outcome was verified by changes in serum alanine transferase level, liver histology, and hepatocyte apoptosis.

RESULTSThe orthogonal array identified the optimal model technique as intraperitoneal injection of a combination of D-GalN and LPS at dosages of 350 mg/kg and 30 mug/kg, respectively, and using a dilution rate of 3. The dosages tested had no effect on survival. The typical signs of liver failure appeared at 6 hrs after administration of the D-GalN/LPS combination.

CONCLUSIONThe orthogonal design optimization strategy provided a procedure for establishing a mouse model of acute liver failure induced by D-GalN and LPS that showed appropriate disease outcome and survival, and which will serve to improve future experimental research of acute liver failure.

OBJECTIVETo observe the difference in the efficacy on lumbar intervertebral disc protrusion (LIDP) between Santong tuina therapy and conventional tuina therapy.

METHODSMulti-central, random and controlled clinical trial was carried out. One hundred and twenty cases of LIDP were randomized into an observation group and a control group, 60 cases in each one. In observation group, Santong tuina therapy was used. In control group, conventional tuina therapy was adopted. The clinical efficacy was observed in two groups, and lumbar vertebral function was scaled before and after treatment in two groups.

RESULTSThe total effective rate was 95.0% (57/60) in observation group and was 96.7% (58/60) in control group, without significant statistical difference in comparison (P > 0.05). The cured and markedly effective rate was 81.7% (49/60) in observation group and was 63.3% (38/60) in control group, indicating significant statistical difference in comparison (P < 0.05). The self-comparison of lumbar vertebral function before and after treatment presented statistical significance in either observation group (12.25 +/- 3.15, 25.56 +/- 5.27) or control group (13.32 +/- 3.26, 20.46 +/- 4.25, both P < 0.05); additionally, there was significant difference in the comparison between groups after treatment (P < 0.05). The therapy adopted in observation group improved lumbar vertebral function much significantly.

CONCLUSIONIn the treatment of LIDP, Santong tuina therapy achieves much better clinical efficacy as compared with conventional tuina therapy.

Objective To observe the clinical efficacy and safety of rituximab injection combined with leflunomide tablets in the treatment of patients with systemic lupus erythematosus(SLE).Methods The SLE patients were divided into control and treatment groups according to cohort method.The control group received leflunomide with 50 mg·d-1 after meal in the first 3 days of treatment and was adjusted to 20 mg·d-1 thereafter.On the basis of control group,the treatment group was combined with rituximab,375 mg·m-2 was given intravenously every 2 weeks in the first 3 times of treatment,and adjusted to once every 4 weeks from the 4th dose.Two groups were treated for 24 weeks.The clinical efficacy,systemic lupus erythematosus disease activity index(SLEDAI)scores,serological indicators,24-hour urinary protein and adverse drug reactions were compared between two groups.Results The treatment and control groups were enrolled 74 cases and 72 cases,respectively.After treatment,the total effective rates of treatment and control groups were 91.89％(68 cases/74 cases)and 79.17％(57 cases/72 cases)with significant difference(P＜0.05).After treatment,the SLEDAI scores of treatment and control groups were(7.21±1.67)and(9.03±1.35)points;the levels of anti-Smith/ribonucleoprotein antibodies were(81.43±18.25)and(59.38±14.61)U·mL-1;the levels of immunoglobulin G were(12.04±2.15)and(17.28±2.64)g·L-1;the levels of interleukin-10 were(33.39±7.13)and(39.87±9.02)pg·mL-1;24-hour urinary protein quantification were(1.46±0.32)and(2.67±0.54)g·24 h-1;all the differences were statistically significant(all P＜0.05).The drug adverse reactions of two groups were liver and kidney function injury and digestive tract reactions.The total incidences of drug adverse reactions in the treatment and control groups were 13.51％and 5.56％without significant difference(P＞0.05).Conclusion Rituximab injection combined with leflunomide tablets has a definitive clinical efficacy in the treatment of SLE patients,which can significantly reduce disease activity and inflammatory reactions,improve immune function,without increasing the incidence of drug adverse reactions.

Objective To determine the incidence and risk factors of HIV infection among heroin addicts receiving methadone maintenance treatment(MMT)in Dehong prefecture,Yunnan province.Methods All heroin addicts who were HIV negative at the initiation of MMT in June 2005 and through June 2011,in Dehong prefecture were included in the cohort analysis.HIV incidence was calculated and related risk factors determined by using Cox proportional hazard regression model.Results A total of 3154 MMT clinic attendants were qualified for this cohort study.By June 2011,1023(32.4％)of them had never received any follow-up HIV testing so were thus referred as loss to follow-up.The other 2131(67.6％)members had received at least one follow-up HIV testing and were observed for a total of 4615.86 person-years.During the period,22 new HIV infections or seroconverters were identified,making the overall HIV incidence as 0.48/100 person-years.The HIV incidence was higher among those who were unemployed,never married,self-reported being injecting drug users(IDUs)and HCV positive at entry into the MMT program.None of those who were always negative on follow-up-urine-testing of morphine was discovered as HIV newly infected during the follow-up period.Data from multiple regression analysis under Cox proportional hazard model indicated that after controlling for confounding variables,non-IDUs at the entry point for the MMT program,were less likely to be HIV newly-infected or seroconverted than IDUs(HR=0.29,95％CI:0.11-0.76).Conclusion MMT prograqm in Dehong prefecture was demonstrated to be fairly effective in reducing HIV transmission through drug use.Those HIV negative attendants at the MMT clinic who were IDUs or keep using drugs during the treatment,were at higher risk of HIV seroconvertion.More efforts were needed to improve the follow-up and HIV testing programs for the MMT clinic attendants.

Objective To compare the effects of 20 mg qd and 10 mg bidadministration of iprrazole enteric-coated tablets on the control of gastric acid in healthy subjects.Methods A randomized,single-center,parallel controlled trial was designed to include 8 healthy subjects.Randomly divided into 2 groups,20 mg qd administration group:20 mg enteric-coated tablets of iprrazole in the morning;10 mg bid administration group:10 mg enteric-coated tablets of iprrazole in the morning and 10 mg in the evening.The pH values in the stomach of the subjects before and 24 h after administration were monitored by pH meter.The plasma concentration of iprazole after administration was determined by HPLC-MS/MS.The main pharmacokinetic parameters were calculated by Phoenix WinNonlin(V8.0)software.Results The PK parameters of iprrazole enteric-coated tablets and reference preparations in fasting group were as follows:The Cmax of 20 mg qd group and 10 mg bid group were(595.75±131.15)and(283.50±96.98)ng·mL-1;AUC0-t were(5 531.94±784.35)and(4 686.67±898.23)h·ng·mL-1;AUC0-∞ were(6 003.19±538.59)and(7 361.48±1 816.77)h·ng·mL-1,respectively.The mean time percentage of gastric pH＞3 after 20 mg qd and 10 mg bid were 82.64％and 61.92％,and the median gastric pH within 24 h were 6.25±1.49 and 3.53±2.05,respectively.The mean gastric pH values within 24 h were 5.71±1.36 and 4.23±1.45,respectively.The correlation analysis of pharmacokinetic/pharmacodynamics showed that there was no significant correlation between the peak concentration of drug in plasma and the inhibitory effect of acid.Conclusion Compared with the 20 mg qd group and the 10 mg bid group,the acid inhibition effect is better,the administration times are less,and the safety of the two administration regimes is good.

Objective To investigate the effect of chemokine CXC ligand 9(CXCL9)on cognitive function impairment in patients with breast cancer brain metastases undergoing whole-brain radiotherapy(WBRT)using bioinformatics methods.Methods The mRNA of breast cancer brain metastases datasets GSE43837 and GSE12276 and Alzheimer's disease(AD)dataset GSE161199 were screened and downloaded from GEO database.Limma method and Venn diagrams were used to identify common differentially expressed genes(DEGs),and protein-protein interaction and functional prediction through GeneMANIA website assays were performed.A total of 42 patients with breast cancer brain metastases who first visited the Department of Radiotherapy at the First Affiliated Hospital of Hebei North University from January 2021 to January 2023 were selected.Patients were divided into normal cognitive function group and cognitive function impairment group based on cognitive status.Enzyme-linked immunosorbent assay(ELISA)was employed to detect serum CXCL9 levels one week before and three months after radiotherapy.The mini-mental state examination(MMSE)was used to assess patients'cognitive function.Results The DEGs from datasets GSE43837 and GSE12276 included PKP1,POLDIP2,SPAG5,ALDOC,PTPRZ1,PKIA,TLCD1,CPE,PMP22 and CXCL9.The DEGs from GSE161199 included RPS16,CD79A,LYPD3,RPL28,HBG2,RPL23AP7,TRNR,CXCL9.Venn diagram showed that CXCL9 was a common DEG between breast cancer brain metastasis and AD.Functional enrichment analysis indicated that CXCL9 was involved in cellular responses to chemokines,negative regulation of immune system processes,negative regulation of vascular morphogenesis,Toll-like receptor signaling pathway,nucleotide oligomerization domain(NOD)-like receptor signaling pathway,and JAK-STAT signaling pathway.Before radiotherapy,patients with cognitive function impairment and normal cognitive function accounted for 61.9%and 38.1%,respectively,with a statistically significant difference in MMSE scores[(24.53±2.19)vs.(28.89±1.36),P＜0.01].Compared with normal cognitive function group,patients with cognitive function impairment had a significantly increased number of brain metastases and significantly lower Karnofsky performance status(KPS)scores and serum CXCL9 levels(P＜0.05).Three months after radiotherapy,patients with cognitive function impairment and normal cognitive function accounted for 47.6%and 52.4%,respectively,with a statistically significant difference in MMSE scores[(25.16±1.98)vs.(28.18±1.08),P＜0.01].Compared with normal cognitive function group,patients with cognitive function impairment had significantly lower CXCL9 levels(P=0.003).In patients with normal cognitive function,CXCL9 levels were remarkably lower after radiotherapy compared to those before radiotherapy(P=0.009).Conclusions Patients with cognitive function impairment had significantly lower CXCL9 levels than those with normal cognitive function,and whole-brain radiotherapy may be related to a certain degree of reduction in CXCL9 levels.

OBJECTIVEIn mid-July 2005, five patients presented with septic shock to a hospital in Ziyang city in Sichuan, China, to identify the etiology of the unknown reason disease, an epidemiological, clinical, and laboratory study were conducted.

METHODSAn enhanced surveillance program were established in Sichuan, the following activities were introduced: active case finding in Sichuan of (a) laboratory diagnosed Streptococcus suis infection and (b) clinically diagnosed probable cases with exposure history; supplemented by (c) monitoring reports on meningococcal meningitis. Streptococcus suis serotype 2 infection was confirmed by culture and biochemical reactions, followed by sequencing for specific genes for serotype and virulence factors.

RESULTSFrom June 10 to August 21, 2005, 68 laboratory confirmed cases of human Streptococcus suis infections were reported. All were villagers who gave a history of direct exposure to deceased or sick pigs in their backyards where slaughtering was performed. Twenty six (38%) presented with toxic shock syndrome of which 15 (58%) died. Other presentations were septicaemia or meningitis. All isolates were tested positive for genes for tuf, species-specific 16S rRNA, cps2J, mrp, ef and sly. There were 136 clinically diagnosed probable cases with similar exposure history but incomplete laboratory investigations.

CONCLUSIONAn outbreak of human Streptococcus suis serotype 2 infections occurred in villagers after direct exposure to deceased or sick pigs in Sichuan. Prohibition of slaughtering in backyards brought the outbreak to a halt. A virulent strain of the bacteria is speculated to be in circulation, and is responsible for the unusual presentation of toxic shock syndrome with high case fatality.

To prepare tanshinone ⅡA loaded nanostructured lipid carrier (Tan ⅡA-NLC), and study its in vitro transdermal permeation characteristics. The Tan ⅡA-NLC was prepared by high pressure homogenization technology and optimized by Box-Behnken design-response surface method, and it was characterized in terms of morphology, particle size, zeta potention, et al. The transdermal permeation of Tan ⅡA-NLC was evaluated by using Franz diffusion cells. The results showed that, the optimal formulation was as follows: drug/lipid materials ratio 88, GMS/MCT ratio 2, emulsifier concentration 1%, average particle size (182±14) nm, polydispersity index PDI (0.190 6±0.024 5), zeta potential (－27.8± 5.4) mV, encapsulation efficiency EE (86.44%±9.26%) and drug loading DL (0.98%±0.18%), respectively. The in vitro transdermal permeation results showed that as compared with Tan ⅡA solution, Tan ⅡA-NLC had lower transdermal permeation amount after applying drug for 24 h, but its retention in the epidermis was 3.18 times that of solution. These results indicated that the prepared Tan ⅡA-NLC could effectively increase the regention of Tan ⅡA in the epidermis, and had a broad application prospect.
