OBJECTIVE To evaluate the cost-effectiveness of iruplinalkib for ALK-positive non-small cell lung cancer(NSCLC)patients who had not previously received ALK-tyrosine kinase inhibitors(TKIs)from the perspective of the Chinese healthcare system.METHODS Based on the INSPIRE clinical trial,a three-health state partitioned survival model was developed to simulate the progression of disease,with model cycle of 3 weeks and a life-year time range of 15 years;the discount rate was 5％.For the treatment of ALK-positive advanced NSCLC,total cost,quality-adjusted life year(QALY),and incremental cost-effectiveness ratio(ICER)were compared between iruplinalkib and crizotinib;using 1-3 times China's per capita gross domestic product(GDP)(89 358-268 074 yuan)in 2023 as the willingness-to-pay(WTP)threshold,the cost-effectiveness of two regimens were compared.The sensitivity analysis and scenario analysis(altering the distribution of survival curves,utility values)were conducted to assess model robustness.RESULTS Compared with the crizotinib regimen,the ICER for the iruplinalkib regimen was 194 412.74 yuan/QALY,which was below the WTP threshold of three times China's per capita GDP in 2023(268 074 yuan).The results under the scenario of altering the survival curve distribution were consistent with the base case analysis.However,after increasing the utility value of the disease progression state,the ICER exceeded the WTP threshold,and iruplinalkib no longer had a cost-effective advantage.The results of the one-way sensitivity analysis indicated that the cost of iruplinalkib and the utility values of disease progression states had a significant impact on the ICER.The probabilistic sensitivity analysis confirmed the robustness of the base case analysis results.CONCLUSIONS From the perspective of China's healthcare system,compared with crizotinib regimen,the therapy with iruplinalkib is cost-effective for ALK-positive NSCLC patients who have not previously received ALK-TKIs.

B7-H3,a member of the B7 family within the immunoglobulin superfamily,is aberrantly expressed in tumor tissues and can be in-duced by immune cells,but is minimally expressed or not expressed in normal tissues.B7-H3 has gained attention for its ability to induce malignant behaviors in tumors and promote cancer progression through various complex pathways.Immunotherapy targeting B7-H3 has shown significant efficacy in clinical trials by modulating the immune system to enhance anti-tumor immune responses.We comprehens-ively summarize the abnormal expression and impact of B7-H3 in various human tumor types,and its role in immunotherapy,highlighting recent advances in clinical research targeting B7-H3.These findings suggest that B7-H3 holds great value as a future target for cancer dia-gnosis and treatment.

Objective: To evaluate the effect and safety of molecular targeted therapy of apatinib mesylate combined with multiple antigen stimulatiing cellular therapy in treatment of osteosarcoma and soft tissue sarcoma. Methods:Six patients with sarcoma were collected by the failure of surgery, radiation and chemotherapy treatment or refusal surgery, radiation and chemotherapy, and at least one month from the last treatment of surgery, radiation and chemotherapy. All of the patients at least received three cycle MASCTTM . From Day 1,everyone were given Apatinib 500 mg,po,qd ,until the disease progression. To measure the patient’s quality of life depending on EORTC QLQ-C30,meanwhile,detecting the cellular immunity function and circulating tumor cells(CTCs) of patients before treatment and one month after 3 cycle MASCTTM . At last, monitoring the cellular immune responses by the Enzyme-linked immuno spot ( ELISPOT) assay. Results: All of the four patients completed the treatment of 3 cycle MASCTTM . Only one patient reduced apatinib from 500 mg to 250 mg because of palmar-plantar erythrodyses-thesia. The response rates of the four patients received MASCTTM and apatinib mesylate after treatment were 1 for complete response (CR),3 for partial response (PR). The life quality and cellular immunity function were improved in all of the patients. ELISPOT assay suggested that the majority of antigen peptides could induce specific cytotoxic T lymphocytes( CTLs) response. The Progression-Free-Survival ( PFS) of four patients received MASCTTM and apatinib mesylate was 7,6,9 and 4 months ,while the response rates of the two patients received apatinib mesylate were 1 for ( Stable disease) SD,one for ( Progression disease) PD. And PFS of the two patients were one month and two months. Conclusion:Combination of MASCTTM and apatinib mesylate is safe,effective and were good prospects for application.

OBJECTIVETo investigate the attitude and sexual behavior status and change among HIV positive female workers in entertainment sites in Kaiyuan city, Yunnan province, China. The key information should be applied in the integrated intervention program in future.

METHODSA cohort survey among HIV positive female workers was conducted during 12 months, between 2010 and 2012. All the risk sexual behavior and attitude were collected for assessment for the potential secondary transmission to sexual partners.

RESULTSOf 99 HIV positive women who sell sex in Kaiyuan city, 99 participated in the survey at baseline, 80, 80, 75, and 75 at 3-, 6-, 9-, and 12-month follow-ups. The percentage of participants who reported consistently used condoms in the last one month ranged between 94.5% and 95.5%. The client volume in the last one month, income per sex and age group were significant related with non-insistent condom use with their clients.

CONCLUSIONIt was suggested that integrated intervention program package should include 100 percent condom use promotion for the HIV positive FSW with all sexual partners, and also, include socially support involved.

Objective To compare the effect of perineal cleansing with the potassium permanganate or sterile water on mid- stream urine culture. Methods Mid- stream specimens of urine were obtained from inpatients in our hospital between January 2002 and December 2006. All these patients may be diag-nosed as urinary tract infection. The urine specimens were divided into the potassium permanganate group (n=1572, the sterilization group) and the sterile water group (n=544). The change of positive and contami-nation rate of mid-stream urine culture from the specimens was observed. More than two kinds of germs in one urine specimen were defined as contamination. Results 830 patients with urinary tract infection had been enrolled. 2116 specimens were collected and 531 strains of causative organism were detected. The positive rate of the sterilization group and the sterile water group was 20.04% and 39.71%, respectively,and such difference was significant. The rate of identical causative organism from the same patient whose spec-imen was cultivated twice in the sterilization group was 0.012% and the rate was 0.105% in the sterile water group. The difference was significant. The rate of different or one kind of causative organism from the same patient whose specimen was cultivated twice in these two groups hadn't significant deviation. The contami-nation rate of the sterilization group (0.028%) was significantly higher than that of the sterile water group (0.007%). Conclusions Perineal cleansing with sterile water can reduce the false negative rate of mid-stream urine culture without increasing the contamination rate. Potassium permanganate sterilization is re-sponsible for the high false-negative in mid-stream urine culture.

Objective To study the clinical efficacy and operative skill of multi-endoscopic technique in treatment of post-traumatic urethrostenosis in male patients.Methods A retrospective analysis was done on clinical data of 47 male patients with post-traumatic urethrostenosis treated with direct visional incision urethrotomy combined with transurethral resection of scar tissue and ureteroscopic incision.There were 29 patients with anterior urethral strictures and 18 with posterior urethral strictures.Results Of all,43 patients underwent successful endoscopic surgeries at the first time but one underwent secondary surgery because of unsuccessful endoscopic incision.These patients achieved satisfactory results without urinary incontinence,fistula or reoperation.The left three patients underwent open surgeries because of unsuccessful endoscopic incision,in which one patient could micturate at maximal flow rate of 9-12 ml/s,without therapeutic urethral dilation,one could micturate under regular therapeutic dilation and the other one could not micturate.Conclusions With the advantages of safety,high success rate and good long-term efficiency,multi-endoscopic technique can be used as an initial treatment for male patients with post-traumatic urethrostenosis and is worthy to be popularized.

The experiment was conducted to prepare chitosan nanoparticles (CNP), to entrap VRMIL-2 with CNP, the eukaryotic VR1020 expression plasmid containing murine IL-2 gene (mlL-2), and to investigate the expression in vivo and the regulatory effect of mIL-2 on immune-response and immuno-protection in mice inoculated muscularly with CNP entrapped VMIL-2 at 21 days old. The results showed that IgG, IgM and IgA contents increased to different degrees in the sera from the inoculated mice, which were remarkably higher than those of the controls inoculated VR1020 packed with CNP (P<0.05); so were the IL-2, IL-4 and IL-6 contents in the sera of the immunized mice. The number of white blood cells and lymphocytes significantly increased respectively in the vaccinated mice, compared with those of controls. These mice were orally challenged with virulent E. coli 35 days post-inoculation, and all the immune responses were significantly higher than those of the control except the number of neutrophils. The mice inoculated with VRMIL-2 survived healthily, while the mice of control group were ill with the evident lesions. Although there are no remarkable differences between the cellular and humoral immune indexes of mice inoculated with CNP-VRMIL-2 and nude VRMIL-2 (P>0.05), the dosage of CNP-VRMIL-2 is only one fifth of the VRMIL-2. These indicated that entrapment of mIL-2 gene with chitosan nanoparticles could remarkably enhance the expression of mIL-2 in vivo, and significantly raise the levels of cellular and humoral immune, and increase the resistance of mice against E. coli infection. The results suggested that chitosan nanoparticles and IL-2 gene could be used as an effective immunoenhancer to increase the immunity of animals against infection.
