OBJECTIVE To provide reference for strengthening the standardized management of off-label drug use in cancer hospitals. METHODS The evaluation system for off-label drug use was established to standardize the application， approval， and filing process for off-label drug use in our hospital. The changes in off-label drug application quantity， proportion， disease category and drug category in our hospital were compared before （October 1st， 2021-September 30th， 2022） and after （October 1st， 2022- September 30th， 2023） the establishment of the evaluation system； drug items supported by high-level evidence screened by pharmacy department were analyzed statistically. RESULTS The number of off-label drug use applications in our hospital had gradually increased， from 306 pieces in the fourth quarter of 2021 to 3 828 pieces in the third quarter of 2023. In the year before the construction of the evaluation system， there were a total of 4 482 applications for off-label drug use， and in the year after the construction of the evaluation system， there were 11 840 applications for off-label drug use. After the construction of the evaluation system， the proportion of unregistered off-label drug use significantly decreased， compared to the same period last year （P＜0.05）. Among them， there were no unregistered applications for off-label drug use for digestive system tumors， head and neck tumors， and radioactive drugs； lymphoma， breast tumors，urogenital system tumors， cytotoxic drugs and new anti-tumor drugs all had a decrease of over 70% in unregistered off-label drug applications. Twenty-seven off-label drug use items related to 19 drugs supported by high-level evidence were screened by the pharmacy department of our hospital， among which 25 items were drug use beyond indication. CONCLUSIONS The establishment of off-label drug use evaluation system in cancer hospital is helpful to the rational use and refined management of clinical anti-tumor drugs.

BACKGROUND:Some patients still have unsatisfactory improvement of operative limb fatigue and pain after total knee arthroplasty.Clinical findings show that Jianpi Yiqi Huoxue Formula can promote recovery after total knee arthroplasty,but the specific efficacy remains to be studied. OBJECTIVE:To observe the effect of Jianpi Yiqi Huoxue Formula on the muscle strength and pain of the operated limb after the primary unilateral total knee arthroplasty. METHODS:A total of 74 patients undergoing primary unilateral total knee arthroplasty were randomly divided into a trial group and a control group with 37 patients in each group.All patients received the same prostheses and surgical methods during the operation.Patients in the control group were treated with routine analgesics,anticoagulant drugs and functional exercise after the operation.The trial group received Jianpi Yiqi Huoxue Formula after the treatment in the control group.Both groups were treated continuously and followed up for 1 month.The changes in isokinetic muscle strength(peak torque and total work amount of extensor and flexor),visual analog scale score and the hospital for special surgery score of the two groups were analyzed. RESULTS AND CONCLUSION:(1)The trial group had better improvement in peak torque and total work amount of extensor and flexor and the hospital for special surgery score than the control group 14 days and 1 month after surgery(P<0.05).(2)In contrast to the control group,the visual analog scale score of the trial group improved better at 7 and 14 days and 1 month after surgery(P<0.05).(3)It is indicated that Jianpi Yiqi Huoxue Formula can effectively improve the muscle strength of the operated limb,enhance the degree of postoperative joint pain,and promote functional rehabilitation after total knee arthroplasty.

Objective To investigate the clinical efficacy and postoperative aortic changes of 3D printing-assisted stent with in-vitro pre-fenestration technique in the treatment of complex type B aortic dissection.Methods A retrospective analysis was conducted on 28 patients with complex type B aortic dissection who underwent thoracic endovascular aortic repair(TEVAR)using stent with in-vitro pre-fenestration technique.The patients were divided into two groups based on the methods of stent with in-vitro pre-fenestration:the 3D printing-assisted stent pre-fenestration group(3D printing group)consisting of 13 patients and traditional stent pre-fenestration group(traditional group)consisting of 15 patients.Various parameters,including hospital duration,surgical duration,duration of stent pre-fenestration in vitro,dose of contrast agent,intraoperative blood loss,immediate postoperative internal leakage rate,30 d postoperative internal leakage rate,30 d postoperative mortality,and the change rate of true and false lumen diameter[the change rate of true and false lumen diameter=(postoperative true and false lumen diameter-preoperative true and false lumen diameter)/preoperative true and false lumen diameter× 100％],were compared between the two groups.Results Compared with the traditional group,the 3D printing group exhibited a considerable reduction in surgical duration[(148.46±27.20)min vs(175.46±22.04)min,P＜0.05].Additionally,the 30 d postoperative type Ⅰ internal leakage rate was lower in the 3D printing group(X2=4.044,P=0.044).Moreover,the change(dilation)rate of true lumen diameter in stent coverage section showed a notable increase in the 3D printing group(P＜0.05).Conclusion The use of 3D printing-assisted stent with in-vitro pre-fenestration has been proven to be safe and effective in the treatment of complex type B aortic dissection.It offers notable advantages,including the reduction of surgical duration,a lower risk of type Ⅰ internal leakage and significant redilation of the true aortic lumen after surgery.

This article reports a case of prenatal diagnosis of fetal Costello syndrome. At 11 weeks of gestation, the fetal nuchal translucency thickness was 2.5 mm. At 26 +1 weeks of gestation, ultrasound indicated that the fetal abdominal circumference was significantly enlarged, suggesting fetal overgrowth. Subsequent regular ultrasound follow-ups revealed polyhydramnios, enlarged fetal kidneys, and macroglossia after 30 +5 weeks of gestation. Whole-exome sequencing of the family detected a c.34G>A(p.Gly12Ser) mutation in the fetal HRAS gene, which was pathogenic and not present in either parent. Based on clinical manifestations, the fetus was diagnosed with Costello syndrome. After genetic counseling, the pregnant woman opted for termination of the pregnancy.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting both upper and lower motor neurons (MNs) with large unmet medical needs. Multiple pathological mechanisms are considered to contribute to the progression of ALS, including neuronal oxidative stress and mitochondrial dysfunction. Honokiol (HNK) has been reported to exert therapeutic effects in several neurologic disease models including ischemia stroke, Alzheimer's disease and Parkinson's disease. Here we found that honokiol also exhibited protective effects in ALS disease models both in vitro and in vivo. Honokiol improved the viability of NSC-34 motor neuron-like cells that expressed the mutant G93A SOD1 proteins (SOD1-G93A cells for short). Mechanistical studies revealed that honokiol alleviated cellular oxidative stress by enhancing glutathione (GSH) synthesis and activating the nuclear factor erythroid 2-related factor 2 (NRF2)-antioxidant response element (ARE) pathway. Also, honokiol improved both mitochondrial function and morphology via fine-tuning mitochondrial dynamics in SOD1-G93A cells. Importantly, honokiol extended the lifespan of the SOD1-G93A transgenic mice and improved the motor function. The improvement of antioxidant capacity and mitochondrial function was further confirmed in the spinal cord and gastrocnemius muscle in mice. Overall, honokiol showed promising preclinical potential as a multiple target drug for ALS treatment.

Objective: To investigate the epidemiological characteristics of sexually transmitted diseases (STDs) in Zhejiang Province from 2018 to 2022, so as to provide insights into improving STDs prevention and control strategies. Methods: Data of syphilis, gonorrhea, condyloma acuminatum, genital herpes and genital Chlamydia trachomatis infections reported in Zhejiang Province from 2018 to 2022 were collected from the Infectious Disease Surveillance System of Chinese Disease Prevention and Control Information System. The temporal, spatial and population distribution of STDs were analyzed, and the trends in incidence of STDs were evaluated using annual percent change (APC). Results: A total of 386 770 STDs cases were reported in Zhejiang Province from 2018 to 2022, with mean annual reported incidence of 127.80/105. The mean annual reported incidence from high to low was syphilis (44.11/105), genital Chlamydia trachomatis infections (40.20/105), gonorrhea (24.92/105), condyloma acuminatum (13.32/105), and genital herpes (5.34/105). The incidence of STDs appeared a tendency towards a decline from 2018 to 2022 (APC=-9.332%, P<0.05), with an average annual growth rate of -9.41%. Syphilis (APC=-11.536%, P<0.05), condyloma acuminatum (APC=-7.509%, P<0.05), and genital Chlamydia trachomatis infections (APC=-9.009%, P<0.05) showed a appeared a tendency towards a decline. The top three highest reported incidence were reported in Hangzhou City (185.98/105), Taizhou City (133.85/105) and Lishui City (122.73/105), respectively. The mean annual reported incidence of females was higher than that of males (140.60/105 vs. 117.83/105; P<0.05). Most STDs cases were at ages of 20 to 49 years (265 314 cases, 68.60%). Farmers (118 096 cases, 30.53%), household and unemployed personnel (85 924 cases, 22.22%) were the predominant occupation. Conclusions The incidence of STDs appeared a tendency towards a decline in Zhejiang Province from 2018 to 2022, with regional differences in incidence. People at ages of 20 to 49 years, farmers, household and unemployed personnel are high-risk populations for STDs.

Objective:To explore the diagnostic efficacy of ultrasonography and follow-up outcomes of hepatic venous outflow obstruction after liver transplantation(LT)in children.Methods:From July 2017 to January 2022, 32 children diagnosed with outflow tract obstruction post-LT are designated as HVOO group and examined by digital subtraction angiography(DSA).All of them underwent balloon dilation.Thirty cases with no vascular complications are selected as control group.Color Doppler blood flow parameters are recorded, including peak systolic velocity(PSV), peak diastolic velocity(PDV), PSV/PDV(S/D), resistive index(RI), portal vein velocity(PVV), hepatic vein velocity(HVV), hepatic vein waveform, anastomotic velocity and waveform.Intravascular pressure values of DSA within 48h are recorded.The correlations between color Doppler flow parameters and intravascular pressure values are examined before and after tube expansion.The differences of color Doppler flow parameters before tube expansion between HVOO and control groups are compared.And receiver operating characteristic(ROC)curves are plotted for obtaining ultrasonic parameters' cut-off value.Patients with excellent recovery are selected for comparing the difference of color Doppler blood flow parameters before and after tube expansion and detect the trend of hemodynamics.Results:There is a positive correlation between anastomotic velocity of hepatic vein and inferior vena cava and DSA before and after tube expansion in HVOO group(r=0.483, 0.414, all P<0.05); S/D, RI and anastomotic velocity are higher in HVOO group than those in control group( Z=-3.275, P=0.001; t=3.437, P=0.001; Z=-5.677, P<0.01); PV and HVV are lower in HVOO group than those in control group( Z=-2.719, P=0.007; Z=-6.762, P<0.01); The waveforms of hepatic vein and anastomosis in HVOO group are mostly single-phase waves, accounting for 81.25%(26/32)and 53.12%(17/32).Control group is mostly of dual-phase wave.According to ROC curve analysis, area under curve(AUC)of HVV diagnosing HVOO is 0.996 with a critical value of 21.65 cm/s; AUC of hepatic vein anastomosis velocity is 0.92 with a critical value 162 cm/s and AUC of RI 0.76 with a critical value of 0.73.PVV and HVV values after tube expansion are higher than before tube expansion( Z=-2.233, P=0.026; Z=-4.45, P<0.01); Anastomotic velocity after tube expansion is lower than that before tube expansion( t=8.584, P<0.01).The waveforms of hepatic vein and anastomosis are mostly of single-phase waves(76.92%, 61.54%)before tube expansion and dual-phase wave(88.46%, 96.15%)after tube expansion. Conclusions:Color Doppler ultrasound is a preferred imaging modality for diagnosing HVOO and conducting postoperative follow-ups in children after LT because of its non-invasiveness, real-time, simplicity and rapidness.Furthermore, the diagnostic efficiencies of hepatic vein and anastomotic velocity are relatively high.

Objective:To study the effects of plan-do-check-action (PDCA) cycle in quality improvement of neonatal resuscitation.Methods:From 2016 to 2020, the clinical data of neonates born in our hospital were analyzed. Neonates born during 2016 to 2017 were pre-PDCA group and neonates born during 2018 to 2020 were post-PDCA group. PDCA quality improvement included step-by-step, high-frequency and low-dose training, strengthening teamwork and adding equipment.Results:A total of 7 728 live-birth neonates were delivered before PDCA with 319 cases (4.1%) of asphyxia. 10 174 live-birth neonates were delivered after PDCA with 422 cases (4.1%) of asphyxia. The asphyxia rates showed no significant difference between the two groups ( P>0.05). The incidences of severe asphyxia before and after PDCA were both 0.8% without significant difference ( P>0.05). The success rates of resuscitation for severe asphyxia before and after PDCA was 27.9% and 44.9%, respectively, and the differences were statistically significant ( P<0.05). The mortality rates within 7 d before and after PDCA were 0.5‰ and 0.1‰ respectively, without significant differences ( P>0.05). Conclusions:The implementation of PDCA cycle and step-by-step, high-frequency, low-dose neonatal resuscitation training can effectively improve the success rate of resuscitation in newborns with severe asphyxia.
