Objective This research aims to investigate the impact of Orff music therapy on long-term schizophrenic patients in hospitals.Methods The study was a randomized,single-blind controlled trial conducted from April,2023 to September,2023.From April to September 2023,sixty-eight individuals diagnosed with persistent schizophrenia were enrolled and evenly distributed into a pair of cohorts:a treatment group of thirty-four people receiving the intervention,and an equal number forming the control group for comparative purposes.Individuals enrolled in the experimental arm of the study were administered Orff-music therapy alongside routine rehabilitation treatment across a span of two months.For a period of 8 weeks,the control group was given only standard rehabilitation treatment,whereas the research group underwent Orff-music therapy in addition to the standard rehabilitation treatment.Results Before treatment,there were no significant differences in the positive and negative symptoms scale(PANSS),the inpatient psychosis rehabilitation observe scale(IPROS)and the personal and social performance scale(psp)between two groups.After intervention,the PANSS showed that the changes were better in the study group than in the control group in 3 indicators:negative symptoms(-3.20±4.13 vs.-0.17±2.43,P<0.001),general symptoms(-2.79±3.83 vs.-0.17±2.99,P=0.003)and the total scores(-5.88±6.36 vs.0.00±4.08,P<0.001),but not in positive symptoms(P>0.05).The IPROS showed that the performances of patients in the study group were better than the control group in terms of participation in work therapy(-0.82±2.08 vs.0.23±2.10,P=0.041),socialization(-0.59±1.94 vs.0.53±1.69,P=0.014)and ability to live(-0.94±2.50 vs.0.15±1.48,P=0.033),the changes in scores before and after the intervention were significantly different when compared to the control group.The PSP showed that the changes in scores before and after the treatment of the study group was better than the control group in terms of social activity[0(-1,0)vs.0(0,0),P=0.011],and self-care[0(-1,0)vs.0(-0.25,0),P=0.012]were better than the control group.Conclusion For long-term hospitalized patients with chronic schizophrenia.Orff-music therapy can be a powerful tool for alleviating mental issues,fostering social functioning,and enhancing rehabilitation results.

Objective:To investigate the safety of minimally invasive liver resection for resectable hepatocellular carcinoma (HCC) complicated with portal hypertension.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 807 patients with resectable HCC who underwent minimally invasive liver resection in 8 medical centers, including Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine et al, from June 2011 to November 2022 were collected. There were 670 males and 137 females, aged 58(50,66)years. Of the 807 patients, 173 cases with portal hypertension were divided into the portal hypertension group, and 634 cases without portal hypertension were divided into the non-portal hypertension group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and post-operative situations; (3) subgroup analysis. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.001. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was constructed using the non-parameter rank sun test. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 807 patients, 268 cases were successfully matched, including 134 cases in the portal hypertension group and 134 cases in the non-portal hypertension group. The elimination of the tumor diameter and robot-assisted surgery confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. The occlusion time of porta hepatis, cases with intraoperative blood transfusion, cases with postoperative complication, cases with complication >Ⅱ grade of Clavien-Dindo classification, cases of Clavien-Dindo classification as Ⅰ grade, Ⅱ grade, Ⅲ grade, Ⅳ grade, cases with liver related complication were 27.0(15.0,43.0)minutes, 33, 55, 15, 13, 29, 14, 1, 37 in the portal hypertension group, versus 35.0(22.0,60.0)minutes, 17, 25, 5, 14, 9, 4, 1, 13 in the non-portal hypertension group, showing significant differences in the above indicators between the two groups ( Z=-2.15, χ2=6.30, 16.39, 4.38, 20.72, 14.16, P<0.05). (3) Subgroup analysis. Results of subgroups analysis showed that in cases with major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 243.5(174.6,296.3)minutes, 200.0(150.0,600.0)mL, 7.5(6.0,13.0)days in the portal hypertension group, versus 270.0(180.0,314.5)minutes, 200.0 (75.0,450.0)mL, 7.0(5.5,10.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.54, -1.73, -0.92, P>0.05). In cases with non-major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 8.0(5.0,10.0)days in the portal hypertension group, versus 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.5,9.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-1.39, -0.10, 1.05, P>0.05). In cases with anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 210.0(150.0,285.0)minutes, 150.0(50.0,200.0)mL, 8.0(6.0,9.3)days in the portal hypertension group, versus 225.5(146.3,306.8)minutes, 100.0(50.0,250.0)mL, 7.0(6.0,9.0)days in the non-portal hypertension group, showing no significant difference in the above indica-tors between the two groups ( Z=-0.75, -0.26, -0.91, P>0.05). In cases with non-anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 173.5(120.0,231.5)minutes, 175.0(50.0,300.0)mL, 7.0(5.0,11.0)days in the portal hyper-tension group, versus 186.0(123.0,262.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.0,9.5)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.97, -1.12, -0.98, P>0.05). Conclusion:Minimally invasive liver resection or even major liver resection is safe and feasible for screened HCC patients complicated with portal hyper-tension, but attention should be paid to the prevention and treatment of postoperative complications.

Objective To compare three-dimensional contrast-enhanced ultrasound ( 3DCEUS) fusion imaging and computed tomography ( CT ) fusion imaging in evaluating ablation margin ( AM ) after radiofrequency ablation ( RFA) for hepatocellular carcinoma ( HCC) . Methods The 3DCEUS images of 60 patients before and after RFA were collected . The AM was evaluated by the self-developed 3DCEUS fusion imaging technique . The consistency of AM evaluation was compared between 3DCEUS and CT fusion imaging . The risk factors of local tumor progression ( LTP) including AM were analyzed . Results The registration success rate of 3DCEUS fusion imaging was 96 .7％ ( 58/60) . Thirty-one cases were in the AM<5 mm group ,and 27 cases were in the AM ≥5 mm group . The consistency of AM evaluation between 3DCEUS and CT fusion imaging was good ( Kappa coefficient = 0 .895 , P < 0 .001) . During a follow-up period ranging 4 .2 to 18 months ,LTP was identified in 5 tumors (8 .6％ ,5/58) .The incidence of LTP with the AM<5 mm was higher than that with the AM ≥5 mm ( P =0 .033) . Conclusions 3DCEUS fusion imaging is feasible for AM evaluation immediately after RFA with high consistency with CT fusion imaging . AM<5 mm evaluated on 3DCEUS fusion immediately after RFA is a risk factor for LTP .

Objective To evaluate the regulatory role of azithromycin-induced persistent Chlamydia trachomatis (Ct) infection in the apoptosis of Hela229 cells.Methods Hela229 cells were firstly co-cultured with Ct for 22 hours,and then cultured with Dulbecco's modified Eagle's medium (DMEM) containing 0.08 mg/L azithromycin for 26 hours to establish a cell model of persistent Ct infection (persistent infection group).These infected Hela229 cells cultured with azithromycin-free DMEM served as a cell model of acute Ct infection (acute infection group).After 48-hour infection with Ct,azithromycin was removed,and infected Hela229 cells in the above 2 groups were successively cultured with DMEM for the resurgence of Ct.Immunofluorescence assay and electron microscopy were performed to verify the persistent Ct infection model.The Hela229 cells in the persistent infection group and acute infection group as well as uninfected Hela229 cells (control group) were treated with staurosporine (STS) for 4 hours to induce the apoptosis,and then cell apoptosis was detected by Hoechst 33258 staining,annexin V/propidium iodide staining and flow cytometry.Results After the treatment with azithromycin,atypical inclusions with aberrant reticulate bodies appeared in the Ct-infected cells.After removing azithromycin,cells were cultured until 96 hours after infection,and infectious elementary bodies reappeared in the Ct inclusions.After the treatment with STS,Hoechst staining showed that there was loose chromatin in the persistently infected cells,while chromatin condensation was observed in the uninfected cells.After 24-hour infection with Ct and 4-hour induction with STS,the apoptosis rate was significantly higher in the persistent infection group (45.567％ ± 2.631％) than in the acute infection group (38.567％ ± 1.701％,t =2.686,P =0.028),but significantly lower in the persistent infection group than in the uninfected group (69.800％ ± 2.835％,t =8.187,P ＜ 0.001).After 48-hour infection with Ct and 4-hour induction with STS,there was a significant difference in the apoptosis rate between the persistent infection group (46.700％ ± 5.257％) and acute infection group (61.767％ ± 1.815％,t =5.781,P ＜ 0.001),as well as between the persistent infection group and the uninfected group (68.667％ ± 3.156％,t =7.421,P ＜ 0.001).Conclusion This study showed that azithromycin-induced persistent Ct infection regulated the apoptosis of host cells,and this effect lasted 48 hours.

Objective To evaluate the safety and effective of ultrasound-guide percutaneous radio frequency ablation (RFA).Methods Retrospectively analyze the incident,management and influence factors of complication of ultrasound-guide percutaneous RFA.Results From 2001 to 2011,536 patients with 762 lesions underwent RFA were enrolled in this study.Incident of RFA complication was 2.03％ (11/536),including 5 (0.92％) major complication.The complication covered fever (1 case),massive hydrothorax (2 cases),hydrothorax accompany with ascites (1 case),massive ascites (1 case),liver abscess (1 case),liver capsule hemorrhage (1 case) and hemothrorax (1 case).No RFA relate mortality was observed.According to logistics regression analysis,the liver function Child-Pugh grading was associated with the RFA complication (P =0.005).Conclusions Ultrasound-guide percutaneous RFA is a safe and effective local treatment approach for hepatocellular carcinoma.It's necessary to comprehensively think over the basic condition of patients and the characters of tumor such as tumor location,size and abutting organs.Nevertheless,an appropriate treatment plan and closely monitor during and after RFA are crucial.

We detected Zika virus (ZIKV) in a febrile case returning from Suriname and entry China from Guangzhou Baiyun International Airport Port.Serum and saliva samples were collected from a suspected case returning from Suriname.We detected ZIKV RNA using real-time fluorescence RT-PCR methods by both in-house reagent and commercial detection kits.RT-PCR detection was carried out with saliva sample and sequence analysis was performed.Phylogenetic tree was constructed to analyze the source of imported cases.Real-time fluorescent RT-PCR result showed that saliva was detected ZIKV RNA positive while for serum was weakly positive.A specific 1 500 bp fragment in size was amplified with saliva sample by RT-PCR.Sequence analysis showed 99％ homologous to the corresponding sequence of Brazil ZIKV (GenBank No.KX197250).Phylogenetic tree indicated it was located on African lineage.According to the epidemiological investigation results,clinical manifestations and nucleic acid detection of case,the suspected case was confirmed to infect Zika virus,being the first case from Suriname into Guangdong Province.

Objective To evaluate the correlation between the imaging features on contrast-enhanced ultrasound (CEUS) and pathological characteristics of combined hepatocellular-cholangiocarcinoma (CHC).Methods Forty patients with pathologically proven hepatic CHC were evaluated,the CEUS imaging findings and pathological characteristics of CHC were retrospectively analyzed.Results On CEUS,peripheral irregular rim-like enhancement,diffuse heterogeneous enhancement and diffuse homogeneous enhancement were illustrated in 13(32.5 ％),21 (52.5 ％) and 6(15.0％) lesions,respectively.Pathological findings showed that HCC-predominance,CC-predominant,and similar proportions of the two components were illustrated in 16 (40.0 ％),19 (47.5 ％) and 5 (12.5 ％) cases,respectively.The presence of necrosis were illustrated in 28 (70.0％) cases.On CEUS,when the enhancement pattern was peripheral irregular rim-like enhancement,CC-predominance and necrosis were presented in 11(84.6％) and 10(76.9％) cases,respectively.When the enhancement pattern was diffuse heterogeneous enhancement,CC-predominance and necrosis were presented in 11(52.4％) and 18(85.7％) cases,respectively.When the enhancement pattern was diffuse homogeneous enhancement,HCC-predominance and necrosis were presented in 4(66.6％) and 0 (0％) cases,respectively.There were significant differences in relative proportion of HCC,CC components and tumor necrosis among the three types of enhancement pattern on CEUS (P =0.009 and P ＜ 0.001).When CHCs were ≤ 5 cm,peripheral irregular rim-like enhancement,diffuse heterogeneous enhancement and diffuse homogeneous enhancement were illustrated in 5,3 and 5 cases,respectively.When CHCs were ＞5 cm,peripheral irregular rim-like enhancement,diffuse heterogeneous enhancement and diffuse homogeneous enhancement were illustrated in 8,18 and 1 cases,respectively.There were significant differences in the three types of enhancement pattern between lesion size of ≤5 cm and ＞5 cm on CEUS (P =0.006).Conclusions The imaging findings of CHC on CEUS depends on the relative proportions of HCC and CC component and on size-dependent patterns.

Objective To comparatively analyze CEUS features of hepatitis B virus (HBV)-related combined hepatocellular-cholangiocarcinoma (CHC) and hepatocellular carcinoma (HCC).Methods Thirty-one patients with HBV-related CHC and 31 patients with HBV-related HCC confirmed by pathology were enrolled and CEUS features were compared.Results On CEUS,HBV-related CHC and HBV-related HCC mainly manifested as hyper-enhanced in arterial phase and hypo-enhanced in portal phase and delayed phase.No significant differences of enhancement level on CEUS were found between HBV-related CHC and HBV-related HCC.When the maximum diameter of tumor ≤3.0 cm,both HBV-related CHC and HBV-related HCC were mainly homogeneous enhancement (P=1.000).When the maximum diameter of tumor more than 3.0 cm,diffuse heterogeneous enhancement and peripheral irregular rim-like enhancement were more commonly observed in HBV-related CHC,while diffuse heterogeneous enhancement was more commonly noted in HBV-related HCC (P=0.001).Conclusion The enhancement pattern of HBV-related CHC ＞3.0 cm has relative specific performance.
