ObjectiveTo observe the healing effect of deep partial thickness burns by the injecting of breviscapine and discuss the possible mechanisms. Methods A rat model of deep partial thickness burns was designed,and was injected with breviscapine.The control group was injected with normal saline.The healing time of burn wound of the two groups was recorded,respectively.Seven days later,the tissues of bum wound of each group were extracted and the contents of hydroxyproline,collagenase-1,nitrogen monoxidum,erythrocuprein,and malonaldehyde that were contained in each extracts were measured.The results of each group were statistically analyzed.ResultsThe healing time of burn wound of the experimental group was [ ( 12 ± 1.428 ) days ],which was significantly shorter than the control group [ ( 14.75 ±1.291 )days] ( P ＜0.05).The contents of hydroxyproline[ (3.17 ± 1.136) mg/g],collagenase-1 [ ( 1.28± 0.651 ) mg/g ],nitrogen monoxidum [ ( 2.62 ± 0.30 ) μmol/gprot ],and erythrocuprein [ ( 221.25 ±25.94) U/mgprot ] in the experimental group were all higher than the control group [ (7.32 ± 2.173 )mg/g,(5.38 ±0.363) mg/g,(7.28 ± 0.40) μmol/gprot,(296.36 ± 29.29) U/mgprot ] ( P ＜ 0.05 or P ＜0.01 ).However,the content of malonaldehyde [ (6.36 ± 0.93 ) nmol/mgprot ] was lower than the control group [ ( 1.25 ± 0.59) nmoL/mgprot ] ( P ＜ 0.05 ).ConclusionsThe breviscapine injection can decurtate the healing time of deep partial thickness bums and it may be related to the extension of blood vessel,improvement of microcirculation,elimination of oxygen free radical,and degradation of lipid peroxidation.

Objective To explore the clinical characteristics and the prognosis of benin convulsions as-sociated with mild gastroenteritis( BICE) in children. Methods To study clinical features of 248 children with BCIE,they followed up for 12 months,and their prognosis were observe. Results Age between 3 months and 3 years,twice or more seizures were occurred on 124 patients. 64 patients suffered the seizures more than 30 mi-nutes. Cranial CT/MRI showed no abnormality. Laboratory examinations were normal, including plasma glu-cose,serum electrolytes and cerebrospinal fluid. Followed up for 12 months,14 patients (5. 6%) suffered from recurrence of BICE,12 patients (4. 8%) suffered from simple febrile seizures,and 8 patients (3. 2%) devel-oped epilepsy. Conclusion The prognosis is good in majority of cases,but some cases may transform febrile seizure or epilepsy. It is more likely to transform epilepsy,when the children suffer from febrile seizure.

Objective To evaluate the efficacy and safety of 650 nm,810 nm diode laser on the treatment of moderate to severe acne.Methods A total of 87 patients with moderate to severe acne were divided into diode laser group (group A) and medication group (group B).In group A,the patients were irradiated with 650,810 nm diode laser at the fluence of 400-450 mW distance of 2-3 cm.In group B,the patients were treated with roxithromycin combined with vitamin B6 and gel lincomycini.Clinical follow-up was performed every week for 4 months.All the adverse effects were recorded.Results There was no significantly statistical difference in the cure rate between the two groups (group A versus group B at 2 weeks:65.0 ％ versus 42.6 ％,P＞0.05; at 4 weeks:92.5 ％ versus 76.5 ％,P＞0.05).However,the recurrence rate of group A was much lower than that of group B (30.0 ％ versus 61.7 ％,P＜0.01).There were no severe adverse effects in both groups during the period of the follow-up.Conclusions Compared to the medication,650,810 nm diode laser appears to be associated with lower recurrence rate in the treatment of moderate to severe acne.

Objective To investigate the effect and mechanism of murine bone marrow mesenchymal stem cells(BM-MSCs)transplantation on B-cell activating factor(BAFF)expression and B cell activation of MRL/Ipr mice.Methods Eighteen female MRL/Ipr mice were divided into the treatment group and the control group.Five female BAL B/C mice were used as negative controls.At the age of 18 weeks,the treatment group was transplanted with 1×10~6 murine BM-MSCs through vena caudalis,the control group was treated with 0.5ml sodium chloride.Enzyme linked immunoserbent assay(ELISA)was used to measure the level of the BAFF,IFN-γ,IL-2 and IL-10 in the serum.The percentage and numbers of Marginal zone,T1 and T2 B cells in spleen were detected by flow cytometry.Results①Eight weeks after transplantation,the level of BAFF [(32±14)ng/ml]in serum of the treatment group decreased significantly than the control group[(47±13)ng/ml](P＜0.05)as well as the level of serum IL- 10,IFN-γ and IL-2 levels[(19±7)vs(40±13)pg/ml](P＜0.01)[(25±20)pg/ml vs(38±25)pg/ml][(73±10)pg/ml vs(80±15)pg/ml].② Eight weeks after trans-plantation,the mice in the treatment group had lower percentages of marginal zone B cells[(15±4)% vs (21±5)%],and the numbers of marginal zone B cells were significantly decreased in the treatment group as compared with the control group[(9±6)×10~6 vs(19±10)×10~6,P＜0.05].③ Eight weeks after transplantation,the mice in the treatment group had lower percentages of T1 and T2 B cells[(3.4±2.1)% vs(7.3±4.0)%][(2.6+1.4)%vs(4.8±2.7)%],and the numbers of T1[(2.7±1.7)×10~6 vs(5.1±2.0)×10~6,P＜0.05]and T2 B cells[(2.0±1.2)×10~6 vs(3.7±1.7)×10~6,P＜0.05]were both significantly decreased in the treatment group as compared with the control group.Conclusion BM-MSCs transplantation decreases the expression of BAFF in association with the diminished production of the pathogenic cytokines IFN-γ and IL-10.Inhibition of BAFF also results in decreased numbers of T1 and T2 B cells and MZ B cells.

OBJECTIVETo observe the difference between the combination therapy of alpha-interferon (IFN-alpha) therapy Yixuesheng Capsule and the monotherapy of IFN-alpha in treatment of chronic hepatitis B.

METHODA total of 288 patients with HBeAg-positive chronic hepatitis B proven by liver biopsy were included in this study. During the individualized therapy, they received hypodermic injection of IFN-alpha 1b, with 5 MU x time(-1) and three times x w(-1). Of them, 125 patients received combination therapy with Yixuesheng Capsule for three months, with 1.0 g/time and three times/d; and 163 patients received only IFN-alpha 1b (the IFN-alpha monotherapy group). After the course of therapy, all patients were followed up for at least 24 months. The intention-to-treat analysis was adopted for statistic analysis.

RESULTThe two groups showed no statistical significance by gender, age, liver necroinflammation grading, liver fibrosis staging, serum ALT levels, serum HBV DNA levels and IFN-alpha therapy course. The whole course and the 24-month follow-up visit cover all of 112 patients in the combination treatment group and 141 cases in the IFN-alpha monotherapy group. The response rates of the combination treatment group and the IFN-alpha monotherapy group were 48.0% (60/125) and 35.0% (57/163) (x = 4.980, P = 0.026) at the end of treatment, respectively, 45.6% (57/125) and 33.1% (54/163) (x2 = 4.645, P =0.031) at the end of 12-month-follow-up period, respectively, and 38.4% (48/125) and 32.5% (53/163) (x2 = 1.076, P = 0.300) at the end of 24-month follow-up period, respectively.

CONCLUSIONThe combination treatment with IFN-alpha and Yixuesheng Capsule shows a slightly better sustained efficacy on HBeAg-positive chronic hepatitis B patients compared with IFN-alpha monotherapy.

ObjectiveTo introduce the Hr gene of spontaneously mutated SHJH^hr mice into BALB/cAShjh inbred mice with clear genetic background,and provide a basis for study on the molecular mechanism of Hr gene mutation-induced abnormal phenotype and the application of this model.Methods Using a backcross-intercross breeding method guided by phenotypic monitoring, mutant genes from SHJH^hr mice bred by spontaneous mutation were introduced into inbred BALB/cAShjh mice by homozygous mutation introgression, and the mice were bred into BALB/cA.Cg.SHJH^hr (abbreviated as C.Cg.SHJH^hr) mice after 10 generations. The genotypes of 90 single nucleotide polymorphism (SNP) detection sites were analyzed in C.Cg.SHJH^hr mice by multiplex PCR library construction followed by next generation sequencing. Then 14 biochemical locus marker genes were detected in C.Cg.SHJH^hr mice according to the method of GB/T 14927.1-2008. Finally, whole genome exon sequencing was utilized to detect the mutated genes in this mouse. ResultsFrom May 2018 to March 2022, a total of 10 generations of backcross-intercross were conducted to complete the construction of the C.Cg.SHJH^hr mouse line. Among the 90 SNPs loci detected, except for rs13484115 and rs13484116, all the other loci had the same genotype as the recipient mice BALB/cAShjh. The results of biochemical marker gene detection showed that all the 14 loci of the mouse were the same as those of the recipient mouse. Whole genome exon sequencing found that the mouse had 109 site mutations compared with the recipient mouse strain, including 71 synonymous mutations, 1 stopgain, 37 missense mutations, and 20 genes involved in protein sequence alterations (including the reported Hr gene). ConclusionC.Cg.SHJH^hr mice were created. Through exon sequencing and genetic analysis, three Hr mutated genes and associated mutated genes that mainly cause phenotypic variations were identified, which provides a basis for expanding the application of C.Cg.SHJH^hr mice in biomedical research.

Objective To measure and analyze biological characteristics and aging phenotype of SHJH^hr mice and provide basic data for the application of the mouse model in aging mechanisms research and antiaging drug development. MethodsWith ICR mice of the same age as control group, the body mass growth data of SHJH^hr mice at the age of 3 to 16 weeks, the reproduction ability of 1 to 4 fetuses and the life cycle of SHJH^hr mice were measured. Blood routine (30 items) and serum biochemical indexes (25 items) of 6-week-old SHJH^hr mice were measured. The venous blood of 8-week-old SHJH^hr mice was collected for flow cytometry analysis to determine the content of immune cells. The aging bone structure of the cancellous bone and bone mineral density of SHJH^hr mice aged 4, 8 and 26 weeks were measured by micro-CT. Histopathological changes of bone and joint of 8-week-old mice were observed. ResultsCompared with ICR mice, the female and male body mass of SHJH^hr mice were significantly lower at the age of 16 weeks (P < 0.05), and the reproductive performance of female mice was low (P < 0.01) or did not have normal reproductive capacity. The shortest survival time of SHJH^hr mice was 57 weeks and the longest was 71 weeks, which was shorter than those of normal ICR mice, showing obvious rapid aging phenomenon. At the same time, some physiological and biochemical indexes of blood and pathological changes of bone and cartilage tissues also showed the accelerated aging and abnormality of animal physiological functions. ConclusionSHJH^hr mice have some biological characteristics of rapid aging as well as some physiological and pathological changes caused by aging.
