Chemotherapy based on cisplatin or its combination therapy is a common cancer treatment method.However,the non-specific side effects of cisplatin,poor pharmacokinetic properties of small molecule drugs,and susceptibility to drug resistance greatly limit the clinical application of cisplatin as first-line anti-tumor drug.With the development of nanocarrier technology,liposomes have become an ideal carrier for delivering cisplatin drugs due to their excellent properties of targeting,reducing toxicity,and enhancing efficacy.This paper reviews the status of cisplatin liposome both domestically and internationally which have entered clinical trials,including L-NDDP,SPI-077?,Lipoplatin?,LiPlaCis,SLIT and 1LC,etc.Currently,only Lipoplatin? and ILC are showing good potential in cancer therapy.Although cisplatin liposome has made some progress in reducing systemic toxicity and improving treatment efficiency in clinical research,there is still potential for further improvement in tumor targeting and reducing side effects.In the future,more low-toxicity and efficient cisplatin liposomes can be developed through formulation technologies such as co-delivery liposome,stimuli-responsive liposome and targeting liposome.

Objective To analyze the basic characteristics of 1885 inpatients with rare diseases in a 3A hospital from January 1 to December 31,2023,so as to provide reference for the management of diagnosis and treatment of rare diseases and the formulation of policies.Methods Based on the medical record homepage data of rare disease inpatients in a tertiary hospital in 2023,analyze the basic characteristics and hospitalization cost structure of rare disease inpatients.Results The hospital ad-mitted 1 885 inpatients with rare diseases in 2023,accounting for 0.81％of the total number of discharged patients,with a male-to-female ratio close to 1:1.Patients aged over 60 accounted for 45.57％,followed by patients aged 45-59(26.47％),patients aged 19-44(20.9％)ranked third,and patients under 18 accounted for less.Rare diseases cover 11 disease classification sys-tems and including 80 diseases,which accounts for 38.65％of the rare diseases in the catalogue.The top ten diseases accounted for 70.56％of the total number of patients,and the top three diseases were progressive fibrosing interstitial lung disease,idio-pathic pulmonary fibrosis and primary biliary cholangitis.Patients under 1 year old accounted for 0.08％,patients aged 2-18 years accounted for 5.19％,patients aged 19-44 years accounted for 19.55％,patients aged 45-59 years accounted for 26.62％,and patients over 60 years old accounted for 48.57％.There was a large difference in the male-female ratio in four diseases:idio-pathic pulmonary fibrosis,amyotrophic lateral sclerosis,Takayasu's arteritis,and primary biliary cholangitis.From the perspec-tive of cost structure,the top ten rare diseases account for a high proportion of diagnosis fees,medicine fees and consumables fees.Conclusion Patients account for a high proportion of rare disease inpatients in the hospital and have a wide coverage of disease types.The overall male-female ratio of patients with rare diseases is similar,but the characteristics of the diseases are dif-ferent.The characteristics of rare diseases determine the structural characteristics of hospitalization expenses.Hospitals should improve the discipline construction and provide more resources for the diagnosis and treatment of rare diseases.To make guide-lines for the diagnosis and treatment of rare diseases and strengthen the training of doctors,so as to realize the early diagnosis and treatment of rare diseases.The state should continue to promote access to medication for rare diseases.

Objective:To evaluate the effect of urethral stent tube irrigation in preventing postoperative complications in adolescents with hypospadias.Methods:A retrospective analysis was conducted using the clinical data of adolescents with hypospadias treated at the Department of Urology, Children’s Hospital of Chongqing Medical University, from April 2016 to July 2023. Patients were divided into control group and study group according to whether urethral stent tube was inserted in urethra during operation. All surgeries were performed by the same surgeon. For two days before surgery, patients were instructed to cleanse the surgical site daily with body wash and a 5% povidone-iodine solution. In the control group, patients received postoperative care with an indwelling urinary catheter. In the study group, in addition to the urinary catheter, a urethral stent tube was placed in the posterior urethra, and postoperative urethral irrigation with saline was performed. Postoperative complications, including wound infection, urethral fistula, urethral stricture, and urethral diverticulum, were monitored. Categorical data were expressed as frequencies and percentages and were analyzed using the χ2 test or Monte Carlo-based χ2 test. Continuous data with normal distribution are presented as Mean±SD and were analyzed using the t-test. Non-normally distributed continuous data were expressed as M ( Q1, Q3) and were analyzed using the Wilcoxon rank-sum test. P<0.05 was considered statistically significant. Results:A total of 76 patients were enrolled in the study, with 43 patients in the control group [median age 12.9(12.2, 13.7) years, reconstructed urethral length (3.88±1.86) cm] and 33 patients in the study group [median age 12.5(11.3, 14.1) years, reconstructed urethral length (3.30±1.45)cm]. Postoperatively, 32 patients (74.4%) in the control group experienced complications, including 24 cases (55.8%) of wound infection, 16 cases (37.2%) of urethral fistula, 6 cases (14.0%) of urethral stricture, and 2 cases (4.7%) of diverticulum. In the study group, only 1 patient (3.0%) developed both wound infection and urethral fistula. The incidence of wound infection, urethral fistula, and overall complications was significantly lower in the study group than in the control group (all P<0.01). Conclusion:Postoperative urethral stent irrigation in adolescents with hypospadias significantly reduces the incidence of wound infection and urethral fistula.

Objective:To investigate the clinical efficacy and possible mechanism of Sanjie analgesic capsule combined with levonorgestrel intrauterine birth control system in the treatment of adenomyosis with phlegm-stasis interjunction.Methods:Eighty-six cases of adenomyosis with phlegm-stasis interjunction were randomly divided into the observation group (44 cases) and the control group (42 cases). The control group was given levonorgestrel intrauterine birth control system treatment, and the observation group was given Sanjie analgesic capsule combined with levonorgestrel intrauterine birth control system treatment. After 6 months of treatment, the traditional Chinese medicine (TCM) syndrome scores, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E 2), progesterone (P), vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2), insulin like growth factor (IGF-1), transforming growth factor-β 1(TGF- β 1), clinical efficacy, adverse reactions were compared between the two groups. Results:After treatment, the TCM syndrome scores in the observation group was lower than that in the control group: (7.57 ± 1.23) scores vs. (9.32 ± 1.45) scores, there was statistical difference ( P<0.05). After treatment, the levels of FSH, LH, E 2, P in the observation group were lower than those in the control group: (5.54 ± 1.21) U/L vs. (7.62 ± 1.36) U/L, (4.43 ± 1.05) U/L vs. (6.14 ± 1.15) U/L, (83.54 ± 12.36) μg/L vs. (92.45 ± 11.56) μg/L, (9.64 ± 1.43) pmol/L vs. (11.36 ± 1.52) pmol/L, there were statistical differences ( P<0.05). After treatment, the levels of VEGF, Ang-2, IGF-1, TGF- β 1 in the observation group were lower than those in the control group: (114.32 ± 15.41) ng/L vs. (162.45 ± 16.32) ng/L, (156.14 ± 20.45) ng/L vs. (186.53 ± 22.36) ng/L, (135.21 ± 15.52) ng/L vs. (151.23 ± 16.21) ng/L, (13.43 ± 2.24) ng/L vs. (16.36 ± 2.51) ng/L, there were statistical differences ( P<0.05). After treatment, the clinical efficacy in the observation group was higher than that in the control group and the adverse reactions was lower than that in the control group: 84.09%(37/44) vs. 64.29%(27/42), 13.64%(6/44) vs. 33.33%(14/42), there were statistical differences ( χ2 = 4.73 and 4.67, P<0.05). Conclusions:For adenomyosis with phlegm-stasis interjunction, the combination of Sanjie analgesic capsule and levonorgestrel intrauterine birth control system can improve the clinical symptoms of patients, improve treatment effectiveness, and reduce the occurrence of adverse reactions, which may be related to factors such as inhibiting estrogen, progesterone and vascular associated growth factors.

Background Schizophrenic patients have metabolic disorders,impaired language and information processing function.Inflammatory factors may play an important role in the occurrence and development of schizophrenia.Objective To explore the relationship of the inflammatory factor levels with metabolic levels,language fluency and information processing function in patients with schizophrenia,so as to provide references for clinical understanding of the neuropathological mechanisms of schizophrenia.Methods A total of 96 patients with schizophrenia were included in the study group,who were hospitalized in the Fourth People's Hospital of Hefei from January 2021 to December 2022 as well as met the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders,fifth edition(DSM-5)and Mini-International Neuropsychiatric Interview(MINI)6.0.Meanwhile,population who underwent physical examination at the same hospital were included in the control group(n=42).A high-sensitivity multi factor electrochemiluminescence analyzer was used to detect the levels of inflammatory factors IL-4,IL-5,IL-7,IL-8,IL-10 and IL-13.A fully automated biochemical analyzer was used to detect the levels of metabolic indicators such as fasting blood glucose,triglycerides,high-density lipoprotein,apolipoprotein A,creatinine and urea nitrogen.Verbal fluency and information processing function of all participants were assessed by using Verbal Fluency Test(VFT)and Stroop Color Word Test(SCWT).Results There were statistically significant differences in the levels of IL-4,IL-5,IL-7,IL-8,IL-10,IL-13 and IL-15 between the study group and the control group(P<0.05).There were statistically significant differences in BMI,waist circumference,fasting blood glucose,triglycerides,high-density lipoprotein,urea nitrogen,apolipoprotein A and creatinine levels between the two groups(P<0.05).The differences in the correct number of household appliances,animals,fruits,vegetables,names starting with"water"and"self"in VFT between the two groups were statistically significant(P<0.05).The differences in point reaction time,character reaction time and character color reaction time in SCWT between the two groups were statistically significant(P<0.05).Correlation analysis showed that except for creatinine levels,the levels of IL-4 and IL-5 in patients with schizophrenia were correlated with other indicators(P<0.05).IL-7 levels were correlated with creatinine levels,household appliances,animals,fruits,correct number of names starting with"water"in VFT,point reaction time and word reaction time in SCWT(P<0.05).IL-8 levels were correlated with triglyceride levels,household appliances,animals,fruits,vegetables,correct number of names starting with"water"and"self"in VFT and word reaction time in SCWT(P<0.05).Except for creatinine levels and the correct number of names starting with"self",IL-10 levels were correlated with all other indicators(P<0.05).Except for creatinine and urea nitrogen levels,IL-13 levels were correlated with other indicators(P<0.05).Conclusion The levels of inflammatory factors in patients with schizophrenia may be related to their metabolic levels,language fluency and information processing function.
