Objective This research is to assess the heterozygosity of Tbx1 gene on 22q11 2 in the patients with conotruncal heart malformation.Methods By fluorescence in situ hybridization (FISH) with partial segment of Tbx1 gene, we examined 22 patients with conotruncal heart malformation including 5 syndromic cases and 17 isolated cases. Northern blot was performed with RNA of 50 human tissues.Results Two of 5 syndromic patients had chromosome 22q11 2 hemizygote microdeletion of the Tbx1 gene, while 17 isolated patients did not show such deletion. Northern blot showed that there were Tbx1 gene positive expression in skeletal muscle, testis, lung and fetal heart.Conclusions Our study suggests that Tbx1 gene may be one of the pathogenic gene related to CATCH22.Association of the Tbx1 gene and conotruncal heart teratogenic gene is to be further detected in gene mutation of patients without heterozygosity deletion.

Based on national and international publications from 2011 to 2022, this review summarizes the application of genomics, proteomics, metabolomics, and microbiomics in the pathogenesis and prediction of HDP, so as to provide insights into the prediction, prevention and precise treatment of HDP.

AIM: To observe the protective effect of naoyikang-containing serum on cultured hippocampus neuron injury induced by D-galactose(D-gal).METHODS: Naoyikang-containing serum was prepared in rats administered with aqueous extract of naoyikang(6.84 g?kg-1?d-1).MTT,MAO-B and ATPase assay were used to measure the viability of hippocampus neurons.RESULTS: D-gal at concentration of 100 ?mol/L caused significant decrease in the viability of hippocampus neurons 24 h after the treatment.Naoyikang-containing serum increased the viability,ATPase activity and the expression of bcl-xl mRNA,decreased the MAO-B activity and the expression of bax mRNA in D-gal injured hippocampus neurons.CONCLUSION: Naoyikang-containing serum prevents hippocampus neurons from D-gal induced cytotoxicity.

OBJECTIVE: Adopting methods of cell culture to explore the effects and mechanisms of Jianpi Bushen Huoxue Prescription (JPBSHXP), a traditional Chinese compound herbal medicine for strengthening spleen, reinforcing kidney and activating blood circulation, in inhibiting hematopoietic cells apoptosis in a mouse model of aplastic anemia (AA). METHODS: Blood serum of AA mice was made from an AA mouse model. Blood serums containing different traditional Chinese compound herbal medicine were made from rats after intragastric administration of JPBSHXP and its related decoctions, respectively. Bone marrow cells of normal mice were incubated by these blood serums for 24 hours, respectively. The apoptosis of the bone marrow cells were assayed by flow cytometry and transmission electron microscopy (TEM). RESULTS: It was indicated that the bone marrow cells of normal mice incubated with blood serum of AA mice displayed typical apoptosis. The apoptosis rates of bone marrow cells of the AA mice incubated by blood serum containing different traditional Chinese herbal medicine were decreased. The effect of Bushen (reinforcing kidey) Recipe was better than Jianpi (strengthening spleen) Recipe and Huoxue (activating blood circulation) Recipe, while the effect of JPBSHXP was the best. TEM results showed that the effect of Bushen Recipe was better than that of the Jianpi Recipe and the Huoxue Recipe, while the effect of JPBSHXP was the best. CONCLUSION: JPBSHXP and its related decoctions can significantly decrease the apoptosis rate of bone marrow mononuclear cells of the AA mice. It is inferred that JPBSHXP can promote bone marrow hematogenesis.

BACKGROUND: Experiments has demonstrated that low-intensity pulse ultrasound stimulations(LIPUS) can accelerate bone healing. However, Its affect mechanisms on maturation of regenerated bone remain unclear.OBJECTIVE: The hypothesis that LIPUS has positive effect on maturation of regenerate bone was put forward creatively, and wants to vedfy the hypothesis by compare the difference between LIPUS intervention and no intervention.METHODS: Thlrty-six adult, healthy, New Zealand White rabbits were randomly assigned to LIPUS treatment group and control.group, with 18 animals in each group.All animals were undergone mid-diaphyeaal tibia ostactomy and were immobilized in Orthofix M103 Mini lengtheners. After a eaven-day latency period, gradual distraction of 0.5 mm per twelve hours for 10 days to produce 10 mm distraction. A 4-weeks course of LIPUS treatment was applled over the distraction site for twenty minutes daily starting immediately after the completion of distraction. At weeks 4, 8, 12 after distraction, the bone healing was evaluated by X-ray film, and total mineralized areas were measured by Image J software. The newly formed bone In the lerigthening field was harvested and stained with haematoxylin-eosin, Masson's tdchroma end VG. Thearaas of newly formed bone were measured to calculate a percentage of the total callus area.RESULTS AND CONCLUSION: Thirty-six rabbits ware included in the final analysis, At week 4 after distraction, the maturation of newly formed bone in LIPUS treatment group appeared eadier than that in the control groups. The bona callus image presented in the marginal and center region of experimental defect, increased greatly and had higher density until filled of the lengthening fields. Many bone-like masses appeared in the newly formed tissues and the tissues surrounding the bone granules partially changed Into bone-like tissues, and the rate of callus production was increased (P ＜ 0.05). There was no significant difference between two groups at weeks 8 and 12 after distraction. Histological results showed that that new bone formation of the LIPUS group was earlier than the control group at weeks 4, 8, and 12 after distraction. The percentage of new bona on total callus area of the LIPUS group was greater than that of the control group at weak 4, but there was no obvious difference at weeks 8 and 12 after distraction. LIPUS accelerates new bone formation, increases the size of the distraction callus, exhibits highly effective in achieving maturation of bone in the animal modal with distraction osteogenesis.

OBJECTIVE: To observe the clinical effect of Shengxueling Granule (SXLG) in treating idiopathic thrombocytopenic purpura (ITP), and to study its possible mechanism. METHODS: Eighty-six cases of ITP were divided into two groups randomly. Fifty-six cases in the treatment group were treated with SXLG, a traditional Chinese medicine, and 30 cases administered with Western medicine (prednisone) were taken as control. Patients in each group took drugs for three months and were under follow-up observation. RESULTS: In SXLG-treated group, the total effective rate in 3 months was 85.71%, similar to 83.33% in prednisone-treated group (P>0.05), while the total effective rate in 6 months in the SXLG-treated group was 91.07%, higher than 53.33% of the prednisone-treated group (P<0.01), and no obvious side-effects were observed. The patients' bleeding was alleviated or stopped, and their general condition was improved. And the blood platelet count (BPC) was increased, the platelet associated immunoglobulin (PAIg) and interleukin-4 (IL-4) were markedly dropped, the level of natural killer cells activity (NKCA) increased, and the rate of T lymphocyte subsets gradually returned to normal level. Megakaryocytes tended toward maturation on bone marrow smear after SXLG treatment. All differences above were statistically significant. CONCLUSION: SXLG is an effective and safe medicine for ITP. It can regulate the cellular immunity, inhibit the platelet antibody to reduce the destruction of the platelet and to increase the number of platelet, promote the differentiation and maturation of megakaryocyte, facilitate the production and release of platelet, lower the fragility of capillary, and prevent the hemorrhagic tendency.
