Objective To observe the clinical efficacy of therapy of resolving blood stasis and tranquilizing mind in the treatment of insomnia with internal blockage of blood stasis type.Methods A parallel randomized controlled trial was conducted on 88 cases of insomnia patients with internal blockage of blood stasis type who admitted to Bao'an Traditional Chinese Medicine Hospital Affiliated to Guangzhou University of Chinese Medicine from January 2024 to June 2024.The patients were randomly divided into an observation group and a control group,with 44 cases in each group.The observation group was treated with the self-made Huayu Anshen Prescription(modified Xuefu Zhuyu Decoction)orally following the therapy of resolving blood stasis and tranquilizing mind,while the control group was treated with Dexzopiclone Tablets orally.The course of treatment for the two groups covered four weeks.The changes in the scores of traditional Chinese medicine(TCM)syndrome,Pittsburgh Sleep Quality Index(PSQI),Self-Rating Depression Scale(SDS),and Self-Rating Anxiety Scale(SAS)in the two groups before and after treatment were observed,and then the clinical efficacy and medication safety of the patients in the two groups were evaluated.Results(1)After four weeks of treatment,the total effective rate of the observation group was 86.36%(38/44)and that of the control group was 70.45%(31/44),and the intergroup comparison showed that the clinical efficacy of the observation group was significantly superior to that of the control group,the difference being statistically significant(χ2=8.080,P<0.05).(2)After treatment,the scores of TCM syndrome,PSQI,SDS,and SAS of patients in the two groups were all significantly decreased compared with those before treatment(P<0.01),and the decrease in the observation group was significantly superior to that in the control group,the differences all being statistically significant(P<0.05).(3)During the treatment,there were no obvious adverse reactions occurred in the two groups,with higher safety.Conclusion Therapy of resolving blood stasis and tranquilizing mind for treating insomnia with internal blockage of blood stasis type can effectively alleviate patients'clinical symptoms,improve their sleep quality and relieve depression and anxiety,with stronger clinical efficacy and higher safety.

Objective:To investigate the clinical efficacy and safety of the triplet regimen of flumatinib, venetoclax (VEN) and azacitidine (AZA) for Philadelphia chromosome-positive (Ph +) mixed-phenotype acute leukemia (MPAL). Methods:The clinical data of 2 Ph + MPAL patients treated with triplet regimen of flumatinib, VEN and AZA who were admitted to the Institute of Hematology & Blood Diseases Hospital of Chinese Academy of Medical Sciences & Peking Union Medical College in February and March 2023 were retrospectively analyzed, and the relevant literature was reviewed. Results:Patient 1 was a 56-year-old female, and patient 2 was a 59-year-old male. Both patients were diagnosed with Ph + B cell/myeloid (B/My) MPAL. After the first course of induction chemotherapy with the triplet regimen, patient 1 achieved hematological complete remission (HCR), complete cytogenetic remission (CCyR) and major molecular response (MMR), and patient 2 achieved HCR and CCyR. During the entire treatment process, the adverse reactions of two patients were mainly fever and ≥ grade 3 hematological adverse reactions, which were relieved after the use of antibiotics and intermittent infusion of blood products. When the patient achieved HCR and received consolidation treatment with the same regimen, the adverse reactions were mild. Conclusions:The triplet regimen of flumatinib, VEN and AZA is safe and effective for the treatment of Ph + MPAL, and is a new induction therapy option for such patients.

Objective To Investigate the efficacy of modified electroconvulsive therapy(MECT)in patients with schizophrenia across different genders.Methods From May 2018 to August 2022,481 patients with schizophrenia were recruited from three psychiatric hospitals in Luzhou,Zigong,and Yibin.According to gender grouping,both groups received adjunctive MECT treatment for two consecutive weeks for a total of six treatments.The differences in positive and negative syndrome scale(PANSS)scores before and after treatment,UKU adverse reaction rating scale(UKU),and gastrointestinal symptom rating scale(GSRS)scores were compared between the two groups.Results After quality control,463 cases were followed up for analysis including 246 males and 217 females.Compared with pre-treatment,the total PANSS score and scores on each subscale were significantly reduced in both genders after treatment(P<0.001).When comparing the reduction rates between the groups,the male patients showed a higher reduction rate in negative symptoms than the female patients(31.24%±30.24%vs.25.80%±33.96%,P<0.05).However,there were no significant differences between the two groups in the reduction rates of the total score,positive symptoms,and general psychopathology(P>0.05).The comparison of adverse reactions showed that the frequency of other types of adverse reactions was higher in female patients than in male patients(47.47%vs.37.80%,P<0.05).However,no significant differences were observed in the adverse reactions related to the mental,neurological,autonomic nervous system,and gastrointestinal systems(P>0.05).Correlation analysis revealed that the reduction rate of the PANSS total score was positively correlated with smoking history(r=0.135,P=0.034)and alcohol history(r=0.160,P=0.012)in male patients,while the reduction rate of the PANSS total score was negatively correlated with the disease duration(r=-0.210,P=0.002)and positively correlated with the age of onset(r=0.145,P=0.032)in female patients.Conclusion MECT is significantly effective for both male and female patients with schizophrenia.Compared to female patients,MECT shows a more pronounced effect on negative symptoms in male patients.Additionally,the factors related to the efficacy of MECT differ between genders,indicating that it is necessary to consider the clinical characteristics of patients comprehensively when selecting an MECT treatment plan.

BackgroundCombination of antipsychotic drugs and modified electroconvulsive therapy （MECT） is currently a commonly used method for treating schizophrenia， but its efficacy varies among different patient groups. ObjectiveTo explore the therapeutic effects of MECT on schizophrenia patients living in different urban versus rural environments， so as to provide references for the selection of treatment plans based on patients' residence. MethodsA total of 587 patients hospitalized at Luzhou Mental Health Center， Zigong Mental Health Center and Yibin Fourth People's Hospital from May 2018 to August 2022， who met the diagnostic criteria for schizophrenia in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） ，were included in the study. Patients were divided into two groups： medication-only group （n=106） and MECT combined with medication group （n=481）. In MECT combined with medication group， 24 rural patients residing in urban areas were excluded， leaving the remaining patients divided into urban group （n=103） and rural group （n=354） based on their place of residence. Positive and Negative Syndrome Scale （PANSS） was used to assess the severity of symptoms. Clinical efficacy was evaluated using PANSS score reduction rate， and covariance analysis was used to compare the therapeutic effects of different patients. ResultsThe differences of reduction rate of PANSS total score， positive symptom scale score and negative symptom scale score as well as treatment effectiveness rate between MECT combined with medication group and medication-only group were statistically significant （F=11.149， 12.111， 31.725， χ²=14.010， P<0.01）. Statistically significant differences were also observed in reduction rate of PANSS total score and positive symptom subscale score as well as treatment effectiveness rate between urban and rural patients in MECT combined with medication group （F=3.946， 4.523， χ²=4.033， P<0.05）. ConclusionThe efficacy of MECT combined with medication may be superior to medication alone in the treatment of schizophrenia， and the combined therapy may be more effective in urban patients than that in rural patients， with potentially more pronounced improvements in positive symptoms.

Objective:To explore the white matter structural characteristics in patients with bipolar disorder(BD)using diffusion tensor imaging(DTI)and investigate their relationship with cognitive function.Methods:A total of 15 patients with BD type Ⅰ and 26 patients with BD type Ⅱ who met the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)diagnostic criteria and 37 normal controls were included.Cognitive function was assessed with the Trail Making Test(TMT)and Repeatable Battery for the Assessment of Neuropsy-chological Status(RBANS).The tract-based spatial statistics(TBSS)method was used to explore the differences in fractional anisotropy(FA)and mean diffusivity(MD)among the three groups and perform correlation analyses with cognitive function.Results:Patients with BD Ⅰ and BD Ⅱ had lower scores in attention(P＜0.001),delayed memory(P＜0.01),and total scores(P＜0.001)on the RBANS compared to the normal control group.They also exhibited lower FA values in the corpus callosum and right superior corona radiata compared to the normal control group(P＜0.05).In the BD Ⅰ group,there was a positive correlation between FA values in the genu of corpus cal-losum and visuospatial/constructional scores(r=0.74,P＜0.05),while in the BD Ⅱ group,a positive correlation was found between FA values in the same region and language function scores(r=0.55,P＜0.05).Conclusion:It suggests that patients with bipolar disorder may have impaired white matter integrity in the corpus callosum and right superior corona radiata,which may be associated with cognitive impairment.

Objective To investigate the value of dual-energy CT quantitative parameters combined with CT features for predicting perineural invasion(PNI)of colorectal adenocarcinoma.Methods Preoperative whole-abdominal CT data of 79 patients with colorectal adenocarcinoma confirmed by postoperative pathology were retrospectively analyzed.The patients were divided into PNI group(n=31)or no PNI group(n=48).Univariate analysis was used to compare CT features and dual-energy CT quantitative parameters between groups,and the variables with significant differences were included in binary logistic regression analysis to construct a combined model.Receiver operating characteristic(ROC)curves were drawn and area under the curve(AUC)were calculated,the efficacy of single CT parameters and combined model for predicting PNI of colorectal adenocarcinoma were evaluated.Results There were significant differences of the location of the primary lesion,the maximum thickness of the diseased intestinal wall,the presence or absence of peritumoral lymph node metastases,peritumoral mesenteric streak shadow and tumor deposits shown on CT between groups(all P＜0.05).Significant differences of the arterial phase slope of energy spectrum curve(λHU),iodine concentration(IC),normalized IC(NIC),dual energy index and the venous phase NIC of dual energy index were found between groups(all P＜0.05).AUC of the above single parameters for predicting PNI of colorectal adenocarcinoma ranged from 0.615 to 0.698,while of the combined model was 0.864.Conclusion Dual-energy CT quantitative parameters combined with CT features could be used to effectively predict PNI of colorectal adenocarcinoma.

Objective To observe the intervention effect of vitamin C (Vit C) and adenosine triphosphate (ATP) on myocardial fibrosis in rats.Methods Forty male SD rats were selected,body weight were 125-140 g,and they were divided into 8 groups according to body weight using a random number table method.Four rats for control group,3 rats for model group,6 rats for Vit C early group,6 rats for ATP early group,6 rats for Vit C + ATP early group,5 rats for Vit C late group,5 rats for ATP late group,and 5 rats for Vit C + ATP late group.Rats in model group and these intervention groups were induced with doxorubicin (2 mg/kg each week) for 6 weeks,and control group was given the same amount of normal saline.All early groups were intragastrically administered with Vit C (200 mg·kg-1·d-1),ATP (45 mg·kg-1·d-1) and Vit C + ATP (200 mg·kg-1·d-1 + 45 mg·kg-1 ·d-1) in the fourth week;these late groups were intragastrically administered with the same dose in the sixth week;each group was continuously administered for 21 days.Three days after the last intervention,cardiac ultrasonography was performed in all surviving rats,and left ventricular end diastolic diameter (LVEDD),left ventricular end systolic diameter (LVESD),left ventricular ejection fraction (LVEF),and left ventricular fractional shortening (LVFS) were recorded.The rats were sacrificed and the hearts were taken.HE staining and Masson staining were used to observe the pathological changes of myocardial tissue and the collagen volume fraction (CVF) was calculate.Serum cardiac troponin Ⅰ (CTn-Ⅰ) and type Ⅰ procollagen amino terminal peptide (PINP) levels were determined by enzyme-linked immunosorbent assay (ELISA).Results Compared with control group [(3.65 ± 0.25) mm,(80.63 ± 3.03)％,(43.57 ± 2.54)％],LVESD [(5.07 ± 0.58),(4.06 ± 0.68),(4.71 ± 0.43),(4.87 ± 0.44),(4.79 ± 0.59),(5.07 ± 0.62),(4.97 ± 0.29) mm] of model group and each intervention groups were increased,LVEF [(62.17 ± 4.92)％,(71.28 ± 3.54)％,(65.03 ± 3.35)％,(59.81 ± 2.45)％,(60.42 ± 9.22)％,(60.15 ± 3.06)％,(60.65 ± 2.05)％],and LVFS [(30.05 ± 2.95)％,(36.44 ± 2.90)％,(31.63 ± 2.15)％,(26.95 ± 1.05)％,(28.35 ± 6.84)％,(27.79 ± 2.41)％,(28.38 ± 1.42)％] were decreased (P ＜ 0.05);compared with model group,LVESD was decreased,LVEF and LVFS were increased in Vit C early group (P ＜ 0.05).HE staining showed that the myocardial pathology of each early group improved to different degrees,such as cardiomyocyte degeneration,necrosis and fibrosis,inflammatory cell infiltration,moderate degree of interstitial edema,Vit C early group and Vit C + ATP early group were more pronounced.Masson staining showed significant improvement in fibrosis in the Vit C early group and Vit C + ATP early group,and collagen fibers were significantly reduced.Compared with the control group [(0.52 ± 0.14)％],the CVF [(27.11 ± 5.05)％,(9.80 ± 1.84)％,(16.55 ± 2.21)％,(5.06 ± 1.45)％,(12.11 ± 2.12)％,(15.71 ± 1.56)％,(16.93 ± 2.76)％] of myocardial tissue in model group and each intervention groups were significantly increased (P ＜ 0.05).There were no significant differences in CTn-Ⅰ and PINP levels between the eight groups (P ＞ 0.05).Conclusions Vit C can reduce myocardial fibrosis and improve cardiac function in the early stage.The effect of ATP alone to improve fibrosis is not obvious.

Objective To explore expression level of circulating microRNA (miR)-133a and Galectin-3 and their potential clinical application in differential diagnosis between patients with chronic Keshan disease and dilated cardiomyopathy.Methods Twenty-eight patients with chronic Keshan disease and 28 cases of age-and sex-matched healthy people as control from the same severe historical endemic areas of Keshan disease in Heilongjiang Province,and another 28 patients with dilated cardiomyopathy from non-affected areas were chosen for the study.All the subjects were asked for disease history and did physical examination,examined by Doppler echocardiography for left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDD),and collected fasting venous blood specimen (elbow vein).The plasma miR-133a and the serum Galectin-3 were determined by Real-time PCR and enzyme-linked immunosorbent method,respectively.Meanwhile,the correlation was analyzed between miR-133a,galectin-3,LVEF and LVEDD.Results The miR-133a and Galectin-3 levels in different groups were statistically different (F =48.789,9.485,P ＜ 0.01).The plasma miR-133a level in chronic Keshan disease group and dilated cardiomyopathy group [median (quartile):0.394 (0.271,0.770),1.665 (0.943,2.713)] were both significantly lower than those in control group [2.382 (1.502,3.302],P ＜ 0.01 or ＜ 0.05],and the plasma miR-133a level in chronic Keshan disease group was lower than that in dilated cardiomyopathy group (P ＜ 0.01).There was no significant difference of serum Galectin-3 level between chronic Keshan disease group and dilated cardiomyopathy group [17.710 (9.624,27.799),12.692 (9.376,26.290) μg/L,P ＞ 0.05],but both were significantly higher than those in control group [8.070 (7.135,9.308) μg/L,P ＜ 0.01].The miR-133a was positively correlated with LVEF (rs =0.297,P ＜ 0.01),while negatively correlated with LVEDD,and Galectin-3 (rs =-0.271,-0.318,P ＜ 0.05 or ＜ 0.01);the serum Galectin-3 was negatively correlated with LVEF (rs =-0.392,P ＜ 0.01),and positively correlated with LVEDD (rs =0.385,P ＜ 0.01).Conclusion The combined application of miR-133a,Galectin-3,LVEF and LVEDD may provide assistance in clinical differential diagnosis of chronic Keshan disease and dilated cardiomyopathy.

Endemic diseases include iodine deficiency disorders,fluorosis,arsenicosis,Keshan disease and Kaschin-Beck disease,which have been well under controlled or basically eliminated so far in China thanks to the great efforts made by our governments and medical staffs over the past decades.We are entering into a new era for consolidation of the achievements.Meanwhile,unprecedented social changes are happening in the diseases affected rural areas of China,which features:first of all,younger generation left and permanent population aging;second,severely polluted natural environment and better housing conditions;third,social transformation from self-sufficient natural economy to commodity economy with improved living standard,but still leaving a certain number of poor farmers and;lastly,backward social security system.However,there are some preferential policies issued in recent years for agriculture,alleviating grass-root social conflicts.All these changes may exert positive or negative influences on combating endemic disease,at least through disease incidence,control measures and surveillance,and further investigations are needed.
