This article was aimed to study the therapeutic effect of Chinese medicine Kun-Bao-W an (KBW) on sleep disorders among ovariectomized mice. A total of 60 female KM of adult mice were randomly divided into four groups, which were the sham-operated group, model group, diazepam group, and KBW group, with 15 rats in each group. Rats in the sham-operated group were only removed small amount of fatty tissue around the ovaries. Bilateral oophorectomy was given on mice in other groups. In the KBW group, 28 days after the operation, KBW was intragastrically administered (1.667 g·kg-1) every day for 28 days. Mice in the diazepam group were intragas-trically administered (1.25 g·kg-1) 1 h before testing. The observation was made on effects of KBW on locomotor activity, sleeping time of mice induced by pentobarbital sodium and the organ coefficients of uterus. The results showed that compared with sham-operated group, locomotor activity and rearing behavior increased obviously in the model group (P < 0.01). The diazepam group can significantly reduce locomotor activity in ovariectomized mice (P < 0.01), and decrease the number of rearing behavior mildly with no statistical difference. KBW can reduce lo-comotor activity mildly but without effect on rearing behavior in ovariectomized mice. Diazepam can markedly pro-long the pentobarbital sleep time in ovariectomized mice (P < 0.01). KBW can prolong the pentobarbital sleep time and shorten the process of falling into sleep mildly with no statistical difference. There was no significant ef-fect on organ coefficients of uterus in ovariectomized mice by KBW or diazepam. It was concluded that KBW had mild effect on improving sleep disorders in ovariectomized mice.

This article was aimed to study the sedative and hypnotic effects of different eluents of Shuangxiatang (SXT). The effects of SXT water decoction, water eluent, 20%, 70% and 95% alcohol eluent on spontaneous ac-tivity and the sleeping induced by subthreshold dose of pentobarbital sodium were measured. The results showed that the SXT decoction, 20% and 95% alcohol eluent can significantly decrease the number of rearing in mice with the percentage of 78.5%, 78.3% and 62.5%, respectively. SXT water eluent and 70% alcohol eluent can significantly decrease the spontaneous activity of mice (P < 0.01), the number of rearing (P < 0.01) and grooming time (P < 0.05). SXT water decoction can significantly shorten sleep latency (P < 0.05), prolong sleep time (P <0.05), and increase rates of sleeping in mice. SXT water eluent can significantly shorten sleep latency in mice (P< 0.05), increase rates of sleeping in mice. SXT water decoction and water eluent have the sedative and hypnotic effects. And the effects are more than alcohol eluents.

Objective:To investigate the correlation between total MRI burden and serum uric acid level in patients with cerebral small vessel disease(CSVD) and its gender differences.Methods:A total of 217 patients with CSVD were retrospectively included as the research objects, and the clinical data such as serum uric acid value were collected.The imaging findings of patients with CSVD were evaluated by MRI, and the total MRI burden score of CSVD was calculated.According to the total MRI burden score of CSVD, patients with CSVD were divided into mild-to-moderate burden group ( n=133) and severe burden group ( n=84). SPSS 20.0 software was used for data analysis and processing.Logistic regression was used to analyze the relationship between uric acid and the total MRI burden score of CSVD. Results:The serum uric acid of severe burden group was higher than that of mild-to-moderate burden group((326.94±70.95)μmol/L, (293.42±80.52)μmol/L, P=0.002). The multivariate logistic regression analysis showed that the elevated level of serum uric acid was an independent risk factors for total MRI burden of CSVD ( β=0.005, OR=1.005, 95% CI=1.001-1.009, P=0.019). The patients with CSVD were equally divided into four group based on the serum uric acid concentration.After controlling the confounding factors, with the increase of uric acid level, the risk of aggravating total MRI burden score of CSVD increased, and the difference was statistically significant( P=0.001). Serum uric acid(for each quartile increase)was an independent risk factor for total MRI burden in male patients with CSVD( β=0.482, OR=1.619, 95% CI=1.125-2.330, P=0.010), while there was no significant difference in female patients( P=0.070). Conclusion:Serum uric acid level is a risk factor for increasing the total MRI burden in male patients with CSVD, but this effect is not found in female patients with CSVD.

BACKGROUND:HLA haploid allogeneic hematopoietic stem cell transplantation provides a chance of survival for patients with high-risk hematologic malignancies.In recent years,the research on the transplantation mode and graft selection of haploidentical transplantation is still ongoing.At present,the mixed transplantation model of non-extracorporeal T-cell removal bone marrow and peripheral blood stem cells established by the Hematology Research Center of Peking University is gradually becoming popular in China,but this model requires the collection of donor bone marrow fluid,which increases the pain and risk of the donor. OBJECTIVE:To explore the curative effect of infusion of umbilical cord mesenchymal stem cells replacing donor bone marrow cells in haploidentical peripheral blood hematopoietic stem cell transplantation for malignant hematological diseases. METHODS:Fifty hematological malignancies patients who underwent haploidentical hematopoietic stem cell transplantation from January 2019 to May 2022 were selected and randomly assigned to two study groups at a ratio of 2:3.Among them,19 patients received umbilical cord mesenchymal stem cell combined with peripheral blood stem cell transplantation,and 31 patients were treated with bone marrow cells combined with peripheral blood stem cells.The study was approved by the Ethics Committee of Henan Provincial People's Hospital.The recipients of umbilical cord mesenchymal stem cells were first transfused with third-party umbilical cord mesenchymal stem cells(1×106/kg)on the day of transplantation,followed by peripheral blood hematopoietic stem cells 6 hours later.In the bone marrow group,donor bone marrow cells were transfused +1 day after transplantation and peripheral blood stem cells were transfused +2 days after transplantation.After transplantation,rabbit anti-human thymocyte immunoglobulin,cyclosporine A,mycophenolate mofetil,and a short-course methotrexate were used for graft-versus-host disease prophylaxis for all recipients. RESULTS AND CONCLUSION:No adverse events occurred during the reinfusion of umbilical cord mesenchymal stem cells.There were no significant differences between the mesenchymal stem cell group and the bone marrow group in the engraftment rate[100%(19/19)vs.96.8%(30/31),P>0.05],median duration for neutrophil engraftment(14 days vs.15 days,P>0.05)and median duration for platelet engraftment(20 days vs.19 days,P>0.05).The incidence of grade Ⅱ-Ⅳ acute graft-versus-host disease in the mesenchymal stem cell group was significantly lower than in the bone marrow group[21.1%(4/19)vs.58.1%(18/31),P = 0.01].There were no significant differences between the two groups in the incidence of chronic graft-versus-host disease[21.1%(4/19)vs.25.8%(8/31),P>0.05],the relapse rates[15.8%(3/19)vs.16.1%(5/31),P>0.05]and the incidence of early cytomegalovirus viremia[42.1%(8/19)vs.35.5%(11/31),P>0.05],and the 2-year overall survival rate[68.4%(10/19)vs.70.9%(16/31),P>0.05].It is indicated that umbilical cord mesenchymal stem cells replace donor bone marrow cells in haploidentical peripheral blood stem cell transplantation for malignant hematological diseases,which reduced the incidence of acute graft-versus-host disease after transplantation,did not increase the incidence of chronic graft-versus-host disease,recurrence rate and early cytomegalovirus viremia,and reduced the pain and risk of donor pulp extraction.

Objective To investigate the epidemiological information of patients in pre-hospital medical care for our large and medium-sized cities and probe the patients' characteristic. Method The data in 2008 were exported from the computer databases of 8 large and medium-sized cities' emergency medical centers in our country.The thorough records of data were conducted to statistical analysis. Results ( 1 ) The scheduling time, running time, rescue time, returning time, total time and service radius in the pre-hospital medical care group were 2.16± 1.10(min), 14.01 ±6.82(min), 12.12±5.96(min), 14.08± 6.85(min), 42.34± 20.21(min)and 8.50±4.18(km), and the above parameter in the non-death group were 2.19 ± 1.13(min), 14.15 ± 7.14(min),11.60±6.72(min), 14.92 ±6.89(min), 41.86± 19.53(minutes) and 8.63±4.31(Km), and the above parameter in the death group were 2.10± 1.08(min), 13.68 ± 7.14(min), 25.25 ± 12.34(min), 13.75±6.48(min), 54.74 ± 25.47(min) and 7.86± 3.91(Km), and the above parameter in the non-sudden cardiac death group were2.09± 1.03(min), 13.58±6.78(min), 25.53± 12.34(min), 13.60± 6.54(min), 53.79±23.77(min) and 7.67 ± 3.86(Km), and the above parameter in the sudden cardiac death group were 2.12 ±1.02(min), 14.10±7.05(min), 24.79± 12.08(min), 13.79±6.61(min), 54. 80 ± 25. 36( min) and 7.90±3.92(Km) respectively. The scheduling time, running time, returning time and service radius in the death group were less than those of the non-death group, but the rescue time and total time of the former were more than those of the latter respectively ( P < 0.05 or P < 0. 001 ). The scheduling time and returning time didn' t have significant difference between the sudden cardiac death group and the non-sudden cardiac death group respectively ( P > 0.05), but the running time, total time and service radius of the sudden cardiac death group were more than those of the non-sudden cardiac death group, and the rescue time of the former was less than that of the latter respectively ( P < 0.05 or P < 0.001 ). (2)The patients' amount in pre-hospital medical care group, the non-death group, the death group, the non-sudden cardiac death group and the sudden cardiac death group were at most in first quarter, and the least time slice of patients' amount were 4:00~ 6:00, 4:00~6:00, 4:00~ 6:00, 22:00~ 24:00, 2:00~4:00 respectively, and the most time slice of patients' amount were 20:00~ 22:00, 20:00~22:00, 8:00~ 10:00, 2:00 ~ 4:00, 8:00 ~ 10:00 respectively. (3)In 241 876 cases of pre-hospital medical care group, the patients' amount of trauma was at most, whose age grades was by far among21 ~50, and the others in sequence were nervous system, circulatory system, other group, digestive system, respiratory system and poisoning group respectively, whose age grades in nervous system, circulatory system and respiratory system was by far above 51, especially above 70. The patients' age grades in other group and digestive system had two climax age groups, which the one was 21 ~ 30, and the other was above 70. The patients' age grades in poisoning group was by far among 21 ~ 50, which the patients' amount of acute alcoholism was at the most. (4) In 12 568 cases of death group, the death amount of circulatory system, other group, respiratory system, nervous system and digestive system ranked at the lst,2nd,4th,5th 8th respectively, whose age grades was by far above 51, especially above 70,and the patients' amount of sudden cardiac death was at the most in the death amount of circulatory system. The death amount of trauma and poisoning group ranked at the 3rd, 6th respectively, whose age grades was by far among 21 ~ 50. (5)The total amount, the death amount and the sudden cardiac death amount of male patients were more than those of female patients. (6)The percentage of the death group to the pre-hospital medical care group was 5.20%, and the percentage of the sudden cardiac death group to the pre-hospital medical care group was 1.29%,and the percentage of the sudden cardiac death group to the death group was 24.87 %, and the percentage of the sudden cardiac death group to the circulatory system group was 67.33 %. Conclusions ( 1 )The trauma and the sudden cardiac death are the overriding reason of disease and the overriding reason of death in our large and medium-sized cities respectively. (2) It is very important to cut the death rate of the middle-old age patients by strengthening prevention and cure of cardiovascular and cerebrovascular diseases, discerning the critical illness early and improving the level of pre-hospital medical care. (3)It is a strong method to decrease the total amount and the death amount of the trauma, especially in traffic accident, by strengthening safety in production, observing traffic regulation and enhancing the legal awareness.
