Objective:To investigate the diagnosis, treatment, clinical characteristics and potential high-risk factors of cerebral venous sinus thrombosis (CVST) during the treatment of acute lymphoblastic leukemia (ALL) with pegaspargase.Methods:The medical history, diagnosis and treatment process, laboratory examination and imaging examination results of 3 ALL patients with CVST during pegaspargase treatment in the First Affiliated Hospital of Suzhou University in March and November 2021 and September 2022 were retrospectively analyzed, and the relevant literature was reviewed.Results:Three patients were all female, with the aged between 15 and 35 years old, including 2 cases of B-ALL and 1 case of T-ALL. All patients developed nervous system symptoms after pegaspargase chemotherapy, and were diagnosed as CVST by imaging examination. During the pegaspargase treatment, 2 patients took norethisterone, and 1 patient underwent induced labor and curettage. The levels of sexual hormones in the 3 patients had non-physiological changes. The main CVST lesions were located in the superior sagittal sinus, transverse sinus and sigmoid sinus. One patient had cerebral hemorrhage at the same time. When thrombus occurred, the fibrinogen (Fib), antithrombin Ⅲ (AT Ⅲ) activity, protein C activity and protein S activity of the patients were significantly lower than those before, D-dimer was significantly higher, and lupus anticoagulant and anticardiolipin antibody were negative. The thrombosis treatment was mainly anticoagulation, and 1 patient underwent thrombolysis. Two patients had no sequelae of nervous system, and 1 patient had the sequelae of muscle weakness.Conclusions:Patients with ALL should be alert to the occurrence of CVST when they have nervous system symptoms during pegaspargase chemotherapy. The diagnosis of CVST mainly depends on cranial imaging. Anticoagulation is the main thrombosis treatment, thrombolysis and interventional thrombectomy are feasible for some patients, with few neurological sequelae. The use of second-generation progesterone drugs and the non-physiological fluctuation of sex hormones may be the potential risk factors of CVST.

Objective To explore the effectiveness of the Five Elements Music Therapy(FEMT)in relieving stress in participants with different cultural backgrounds,and to compare the differences between the FEMT and the Western Art Music Therapy(WAMT)in stress relief.Methods This was a comparative pilot randomized pre-post repeated measures study,37 subjects were allocated with 2 dropped out,with an inclusion-ended sample of 35 subjects,23 from Canada and 12 from China.After informed consent,all subjects were randomly assigned to listening to either Five Elements Music or Western Art Music at home for 30 minutes,twice a week for four weeks.Participants were asked to use headphones,measure their pulse rate before and after each session,and fill out five questionnaires,including a background and demographic survey(reporting age,gender,education,cultural background,listening experience).Self-assessment of stress(pre-post after each session),General Hospital Anxiety/Depression Scale(HADS,weekly after 2nd session),Perceived Stress Survey(PSS,weekly after 2nd session),the Music Therapy Intervention Survey(MTIS,pre-post each session).Results ①There was a significant decrease in self-assessed stress scores after the second session in the FEMT compared with the WAMT group(t=-2.057,P=0.046).②In both groups,there was a significant decrease in stress scores pre-post treatment in each group(WAMT t=5.026;FEMT T=7.645,P=0.000).③There was no significant difference between the two groups in post-intervention HADS scores(P>0.05);In the Chinese sample,there was a significant difference in HADS scores after the eighth session in both FEMT and WAMT groups(t=-3.862,P=0.003),and a statistically significant difference in HADS pre-post intervention in the FEMT((t=5.117,P=0.004).There was a significant difference in MTIS pre-post treatment in the WAMT(t=-2.572,P=0.023),but in not the FEMT group(t= 1.331,P=0.207).Conclusion This pilot trial explores a safe and feasible self-administered music therapy approach for stress in two distinct cultural groups,and for the first time provides preliminary comparison and evidence of effectiveness of FEMT and WAMT in alleviating stress and anxiety.Further investigation with bigger randomized samples is needed to elucidate the effects of different kinds of music and cultural groups on stress and anxiety levels.

Objective:To evaluate the analgesic efficacy of pericapsular nerve group (PENG) block in elderly patients undergoing hip replacement under subarachnoid block.Methods:Fifty patients of both sexes, aged 65-89 yr, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with body mass index 20-30 kg/m 2, undergoing unilateral hip arthroplasty, were divided into 2 groups ( n=25 each) by a random number table method: PENG group and fascia iliaca compartment block (FICB) group.In PENG group, 0.4% ropivacaine hydrochloride 20 ml was injected around the nerve innervating the hip joint capsule under ultrasound guidance.In FICB group, 0.4% ropivacaine 30 ml was injected around the nerve innervating the fascia iliaca compartment under ultrasound guidance.Subarachnoid block was performed in both groups.Visual analog scale scores and scores for satisfaction with analgesia at rest and during activity were recorded before blockade (T 0), at 10, 20 and 30 min after blockade (T 1-3) and when placed in the position for spinal anesthesia (T 4). The cumulative consumption of sufentanil, effective pressing times of analgesic pump, and development of related complications were recorded at 6, 12, 24 and 48 h after operation (T 5-8). Results:Compared with FICB group, the VAS scores at rest and during activity were significantly decreased at T 1-4, and scores for satisfaction with analgesia during activity were increased in PENG group ( P<0.05). There was no significant difference between the two groups in the cumulative consumption of sufentanil and effective pressing times of analgesic pump ( P>0.05). One patient developed postoperative delirium in group FICB, and no patients developed puncture site infection and nerve damage after operation in two groups. Conclusion:PENG block produces better analgesic efficacy than FICB when used for elderly patients undergoing hip replacement under subarachnoid block.

Objective: To observe the material basis and mechanism of action of Kai-Xin-San (KXS) in regulating antidepression of neurotrophic factors. Methods: KXS eluted by ethanol on macroporous resin was prepared. The antidepressive effect of different components was compared by tailing suspension test and forced swimming test of mice. The levels of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) in hippocampus were determined by ELISA. The rat astrocyte glioma C6 cell line and the rat adrenal pheochromocytoma PC12 cell line were used to evaluate the effects of different ethanol elution sites on the expression of NGF and BDNF and the differentiation of PC12 cells.Results: All of the ethanol elution components from KXS exerted anti-depressive effects by shorting the immobile time of tailing suspension and forced swimming of mice and 70％ ethanol elution components exerted best efficacy. This site also could increase expressions of NGF and BDNF on C6 glioma cell line. The 10％ ethanol elution site had the strongest ability to promote PC12 cell differentiation. Ginsenosides were the main effectuve ingredients for promoting the expression of neurotrophic factors. Conclusion: Regulation of neurotrophic factors might be the prominent action mechanism of KXS exerting anti-depressive effects.

AIM:To explore the effects of stanniocalcin 2 (STC2) on the proliferation, migration and the process of epithelial-mesenchymal transition (EMT) in human hepatocellular carcinoma HepG2 cells.METHODS:The expression levels of STC2 in the hepatocellular carcinoma cell lines and normal liver cells were assessed by Western blot.Colony formation assay was used to test the effect of STC2 on the proliferation of HepG2 cells.The effects of STC2 on the expression of proliferation-related molecules at mRNA and protein levels were determined by RT-qPCR and Western blot.The effect of STC2 on the migration ability was measured by Transwell assay.The mRNA and protein levels of vimentin and E-cadherin in STC2-overexpressing and-silencing cell lines were detected by RT-qPCR and Western blot.RESULTS:Compared with the normal liver cell line, the protein expression of STC2 was up-regulated in the hepatocellular carcinoma cell lines.The results of colony formation assay indicated that STC2 promoted the proliferation of HepG2 cells.STC2 significantly regulated the proliferation-related gene expression, such as cyclin D1.The results of Transwell assay showed that STC2 enhanced the migration ability of the HepG2 cells and influenced the EMT process.CONCLUSION:STC2 promotes the proliferation of HepG2 cells and affects the expression of proliferation-related genes.STC2 influences the process of EMT and promotes the migration of HepG2 cells.

AIM:To explore the mitochondrial pathway in the apoptosis of PC3 cells induced by PXD101 (also named as belinostat).METHODS:PC3 cells were treated with PXD101 at different doses or stimulated with PXD101 for different time.The effect of PXD101 on the viability of PC3 cells was measured by CCK-8 assay.The apoptotic rates and the mitochondrial membrane potential (MMP) were analyzed by flow cytometry.The protein levels of Bcl-2, Bax and cytochrome C (Cyt C) were determined by Western blot.The caspase-3 activity were tested by caspase-3 activity assay kit.RESULTS:The viability of the PC3 cells was inhibited by PXD101 in a dose-and time-dependent manner.Flow cytometric analysis showed that the apoptotic rates were increased in the cells treated with PXD101 (P<0.01).At the same time, PXD101 induced the decreases in MMP and Bcl-2, the release of Cyt C, and the increase in caspase-3 activity.CONCLUSION:PXD101 induces the apoptosis of human prostate cancer cell line PC3 by mitochondrial signal pathway.

Objective To evaluate the feasibility and accuracy of virtual navigation contrast enhanced sonography in accurately location of small liver tumors which cannot be detected by conventional sonography during microwave ablation therapy. Methods Twenty-three patients with 28 small liver tumors,which could not be detected by conventional sonography but CT/MRI,underwent microwave ablation with virtual navigation contrast enhanced sonography from January 2015 to March 2017 at Nanfang Hospital. After fusion of images from both sonography and CT/MRI,small liver tumors were ablated under the real-time monitoring of navigated sonography. Virtual navigation contrast enhanced sonography was also utilized to evaluate the efficacy of ablation after the ablation.All patients underwent CT/MRI examination at one month post-ablation to evaluate the efficacy of ablation. Results Virtual navigation system successfully provided image fusion for all patients and all lesions(image fusion efficacy was 100%). All patients underwent virtual navigation contrast enhanced sonography monitored microwave ablation.Only one patient received extra ablation since a small proportion of residual tumor checked after the initial ablation. No severe complications occurred in the present study. One-month after ablation,all patients showed complete ablation by further CT/MRI examinations.Conclusion Virtual navigation sonography can precisely target small liver tumors which are undetected by conventional sonography.Evaluation of lesions and ablation efficacy can be performed with the help of virtual navigation contrast enhanced sonography during the ablation period,which have shown satisfactory clinical efficacy.
