Objective:To analyze the prognostic value of del(1p32)in patients with newly diagnosed multiple myeloma(MM).Methods:The clinical data of 341 newly diagnosed MM attended in Jiangsu Province Hospital were retrospective analyzed.Clinical characteristic combined with genetic features,especially del(1p32),were analyzed for survival and prognostic of patients.Results:Among the 341 patients with newly diagnosed MM,24(7.0％)patients were del(1p32)positive.The progression-free survival(PFS)and overall survival(OS)were significantly shorter in MM patients with del(1p3 2)than those without de1(1p32)(PFS:P＜0.001;OS:P＜0.001).The COX proportional-hazards model showed that del(1 p32)was an independent risk factor for PFS and OS of patients with MM.The patients with both 1q21 gain/amplification and del(1p32),as"double-hit chromosome 1",have worse prognosis than those with only 1q21 gain/amplification or only del(1 p32)(PFS:P＜0.001;OS:P＜0.001).Conclusion:Del(1p32)is an independent risk factor for PFS and OS of patients with MM.Del(1p32)detection should be widely used in the prognostic analysis for newly diagnosed MM patients.

This study aimed to investigate the therapeutic effect of Yunkang Oral Solution on the improvement of spleen deficiency and pregnancy outcomes in pregnant mice with spleen deficiency syndrome induced by irregular diet and over consumption of cold and bitter foods. To simulate human irregular diet and over consumption of cold and bitter foods leading to spleen deficiency, the pregnant mice with spleen deficiency syndrome were prepared using an alternate-day fasting and high-fat diet combined with oral administration of Sennae Folium. During the experiment, spleen deficiency-related indicators and diarrhea-related parameters were measured. Gastric and intestinal motility(gastric emptying rate and intestinal propulsion rate) were evaluated. The levels of serum ghrelin, growth hormone(GH), gastrin(Gas), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-c), chorionic gonadotropin β(β-CG), progesterone(P), and estradiol(E_2) were measured. Intestinal barrier function in pregnant mice with spleen deficiency syndrome was assessed. Conception rate, ovarian coefficient, litter-bearing uterine coefficient, number of live fetuses, average fetal weight, and fetal length were calculated. The results showed that Yunkang Oral Solution significantly improved spleen deficiency-related indicators and diarrhea in pregnant mice with spleen deficiency syndrome, increased gastric emptying rate and intestinal propulsion rate, elevated the levels of gastrointestinal hormones(ghrelin, GH, and Gas) in the serum, and reduced lipid levels(TC and LDL-c), thereby improving lipid metabolism disorders. It also improved colonic tissue morphology, increased the number of goblet cells, and promoted the mRNA and protein expression of occludin and claudin-1 in colonic tissues, thereby alleviating intestinal barrier damage. Yunkang Oral Solution also regulated the levels of pregnancy hormones(β-CG, P, and E_2) in the serum of pregnant mice with spleen deficiency syndrome. Moreover, it increased the conception rate, ovarian coefficient, litter-bearing uterine coefficient, number of live fetuses, average fetal weight, and fetal length. These findings suggest that Yunkang Oral Solution can improve spleen deficiency-related symptoms in pregnant mice before and during pregnancy, regulate pregnancy-related hormones, and improve pregnancy outcomes.

OBJECTIVE: To investigate the effects of melatonin on the growth and metastasis of MDA-MB-231 breast cancer cells and explore the mechanism. METHODS: MDA-MB-231 cells were treated with 1, 3 or 5 mmol/L melatonin, and the changes in cell proliferation were examined using CCK-8 assay. Colony-forming assay and wound healing assay were used to assess the effects of melatonin treatmnent on colony-forming ability and migration of the cells. Flow cytometry and immunofluoresnce assay were employed to examine apoptosis and positive staining for autophagy-related proteins in the cells treated with 3 mmol/L melatonin. The effects of melatonin treatment alone or in combination with 3-methyladenine (3-MA) on the expressions of the proteins associated with autophagy (LC3, P62 and Beclin1), apoptosis (Bcl2 and Bax) and epithelial-mesenchymal transition (E-cadherin and Snail) were examined with Western blotting. RESULTS: Melatonin treatment significantly inhibited the proliferation of breast cancer cells in a concentration- and time-dependent manner (P < 0.05), suppressed colony-forming ability and migration (P < 0.01), and promoted apoptosis of the cells (P < 0.01). Melatonin treatment alone significantly increased the expressions of Bax (P < 0.05), E-cadherin, LC3-II/LC3-I, and Beclin1 and lowered the expressions of Bcl2 (P < 0.05), Snail, P62 (P < 0.05), and Bcl2/Bax ratio (P < 0.01) in the cells, and caused enhanced positive staining of Beclin1 protein and attenuated staining of P62 protein. Compared with melatonin treatment alone, melatonin treatment combined with 3-MA significantly decreased the expressions of Beclin1 (P < 0.001), LC3-II/LC3-I (P < 0.05), Bax (P < 0.01), and E-cadherin (P < 0.001) and increased the expressions of Bcl2 (P < 0.05), Snail, and Bcl2/Bax ratio (P < 0.01). CONCLUSION Melatonin can induce autophagy of MDA-MB-231 breast cancer cells to inhibit cell proliferation and metastasis and promote cell apoptosis, and suppressing autophagy can weaken the inhibitory effect of melatonin on the growth and metastasis of breast cancer cells.

ObjectiveTo observe the effect of Xianlian Jiedu prescription （XLJDP） on the proliferation， apoptosis， and migration of cancer-relative endothelial （CRE） cells， and to decipher the mechanism of XLJDP in regulating angiopoietin2 （Ang2） to maintain CRE cell homeostasis and inhibit tumor neovascularization. MethodHuman umbilical vein endothelial cell line （HUVEC-c） was induced into CRE cells in the human colorectal cancer HCT-116 cell-conditioned medium. The CRE cells were assigned into the blank group， conditioned medium group， and XLJDP groups （1， 2， 3 g·L^-1） and treated for 48 h. The proliferation of CRE cells was detected by methyl thiazolyl tetrazolium （MTT） colorimetry. The morphological changes of CRE cells were observed via an inverted microscope. The apoptosis rate was detected by flow cytometry. Wound healing test and Transwell migration assay were employed to detect the 2D/3D migration ability of CRE cells. The protein levels of vimentin， N-cadherin， matrix metalloproteinase-9 （MMP-9）， and Ang2 in CRE cells were measured by Western blot. ResultThe MTT results showed that the cell viability was higher in the conditioned medium group than in the blank group （P<0.05）. Compared with the conditioned medium group， XLJDP decreased the cell proliferation rate （P<0.01） and changed the cell morphology. The total apoptosis rates of all the XLJDP groups were higher than that of the conditioned medium group （P<0.01）. The 2D and 3D migration abilities of the conditioned medium group were higher than those of the blank group （P<0.05， P<0.01）. Compared with the conditioned medium group， XLJDP at all the concentrations weakened the 2D migration ability （P<0.01） and medium- and high-concentration XLJDP weakened the 3D migration ability （P<0.01）. The protein levels of N-cadherin， Vimentin， MMP-9， and Ang2 were up-regulated in the conditioned medium group compared with those in the blank group （P<0.05， P<0.01）. Compared with the conditioned medium group， XLJDP at all the concentrations down-regulated the protein level of Ang2 （P<0.05， P<0.01）， and medium- and high-concentration XLJDP down-regulated those of N-cadherin， vimentin， and MMP-9 protein （P<0.01）. ConclusionXLJDP may inhibit the proliferation， migration， differentiation， and apoptosis of CRE cells by down-regulating the expression of Ang2， inhibiting tumor neovascularization， and maintaining the cell homeostasis.

BACKGROUND: Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China. METHODS: The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD. RESULTS: A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05). CONCLUSION Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.

Objective: To observe the clinical efficacy of DZWJY-1 type electronic moxibustion apparatus and traditional moxibustion in treating knee osteoarthritis (KOA). Methods: A total of 76 eligible patients were randomized into an electronic moxibustion apparatus group and a traditional moxibustion group, with 38 cases in each group. The electronic moxibustion apparatus group was intervened by DZWJY-1 type electronic moxibustion apparatus, and the traditional moxibustion group received moxa stick moxibustion for treatment. Neixiyan (EX-LE 4), Dubi (ST 35), Xuehai (SP 10) and Liangqiu (ST 34) were selected for both groups and the treatment was conducted 3 times a week for a total of 12 times. The visual analog scale (VAS) and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) scores were observed before treatment and after 6 and 12 sessions of treatment, respectively. Results: There were 4 dropout cases in the traditional moxibustion group. Therefore, this trial had 72 valid cases, including 38 cases in the electronic moxibustion apparatus group and 34 cases in the traditional moxibustion group, the differences in the baseline data between the two groups were statistically insignificant (P>0.05). After 6 and 12 sessions of treatment, the VAS scores decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the betweengroup differences were statistically insignificant at the same time points (both P>0.05). The pain intensity was evaluated using the weighted value of VAS score. The markedly effective rate was 47.4％ and the total effective rate was 89.5％ in the electronic moxibustion apparatus group, versus 50.0％ and 94.1％ in the traditional moxibustion group, and the betweengroup differences were statistically insignificant (both P>0.05). After 6 and 12 sessions of treatment, the total score and the component scores including pain, stiffness and difficulty moving in the WOMAC decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the between-group differences were statistically insignificant (all P>0.05). Conclusion: Electronic moxibustion apparatus and traditional moxibustion both are effective in reducing joint pain and improving joint function in KOA patients, and they are equivalent comparing the clinical efficacy.

OBJECTIVE: To investigate the expression of CD123 in patients with acute myeloid leukemia (AML) and its relationship between clinical features, concomitant fusion gene or gene mutation, efficacy and prognosis. METHODS: 365 patients with newly diagnosed AML (except M3) treated in the First Affiliated Hospital of Zhengzhou University were enrolled and retrospective analysis, and multi-parameter flow cytometry was performed to detect the expression of CD123 in myeloid leukemia cell population. CD123≥20% was defined as positive. Clinical features, concomitant fusion gene or gene mutation, efficacy and prognosis of CD123 RESULTS: The positive rate of CD123 in 365 newly diagnosed AML patients was 38.9%. Compared with the CD123 CONCLUSION CD123 positive indicates that AML patients have higher tumor burden and are more difficult to reach remission. It is an independent risk factor for OS and EFS in patients with normal karyotype and intermediate risk, which is important to evaluate the prognosis of patients with AML without specific prognostic marker.

Objective: To investigate the spectrum of gene mutations in adult patients with B-acute lymphoblastic leukemia (B-ALL), and to analyze the influences of different gene mutations on prognosis. Methods: DNA samples from 113 adult B-ALL patients who administered from June 2009 to September 2015 were collected. Target-specific next generation sequencing (NGS) approach was used to analyze the mutations of 112 genes (focused on the specific mutational hotspots) and all putative mutations were compared against multiple databases to calculate the frequency spectrum. The impact of gene mutation on the patients' overall survival (OS) and recurrence free survival (RFS) was analyzed by the putative mutations through Kaplan-Meier, and Cox regression methods. Results: Of the 113 patients, 103 (92.0%) harbored at least one mutation and 29 (25.6%) harbored more than 3 genes mutation. The five most frequently mutated genes in B-ALL are SF1, FAT1, MPL, PTPN11 and NRAS. Gene mutations are different between Ph⁺ B-ALL and Ph^- B-ALL patients. Ph^- B-ALL patients with JAK-STAT signal pathway related gene mutation, such as JAK1/JAK2 mutation showed a poor prognosis compared to the patients without mutation (OS: P=0.011, 0.001; RFS: P=0.014,<0.001). Patients with PTPN11 mutation showed better survival than those without mutation, but the difference was not statistically significant (P value > 0.05). Besides, in Ph⁺ B-ALL patients whose epigenetic modifications related signaling pathway genes were affected, they had a worse prognosis (OS: P=0.038; RFS: P=0.047). Conclusion: Gene mutations are common in adult ALL patients, a variety of signaling pathways are involved. The frequency and spectrum are varied in different types of B-ALL. JAK family gene mutation usually indicates poor prognosis. The co-occurrence of somatic mutations in adult B-ALL patients indicate the genetic complex and instability of adult B-ALL patients.

OBJECTIVETo explore the mechanism of Bushen Qiangji Granule (, BSQJ) in restraining the osteogenic differentiation of ankylosing spondylitis (AS) fifibroblasts.

METHODSHip joint capsules were obtained from AS patients (n=10) receiving total hip replacement and healthy hip joint capsules from patients with hip fracture (n=10) receiving surgery as a control. Finite fifibroblast lines were established from these tissue samples to observe the effect of BSQJ on suppressing osteogenic differentiation of fifibroblasts. The expression of osteogenic marker gene corebinding factor a1 (Cbfa1) and Smad family proteins were examined by Western blot and real-time quantitative polymerase chain reaction (qPCR).

RESULTSThe mRNA expression level of Cbfa1 was significantly higher in AS fibroblasts than that in normal fibroblasts and the expression of pSmad1, pSmad5, Smad4 and Cbfa1 in AS fibroblasts was also higher, demonstrating the activation of the BMP/Smads signal pathway in AS fifibroblasts. BSQJ-medicated serum not only restrained the mRNA and protein expression levels of Cbfa1 and inhibited protein expression level of Smad4 but also decreased the expression quantities of pSmad1 and pSmad5.

CONCLUSIONSBSQJ can inhibit osteogenic differentiation of AS fifibroblasts in vitro by suppressing the activation of the BMP/Smads signal pathway. This may be the important molecular mechanism of BSQJ in regulating AS ossifification.

BACKGROUND:To dynamicaly monitor the varying levels of inflammatory factors in the gingival crevicular fluid is helpful to assess the early effect of orthodontic tooth movement. Myeloperoxidase, soluble intercelular adhesion molecule-1, pentraxin 3 are proven to be closely related to inflammation, but it is unclear about the levels of these three kinds of inflammatory factors as wel as association of these three kinds of inflammatory factors with orthodontic tooth. OBJECTIVE:To detect the expression levels of myeloperoxidase, soluble intercelular adhesion molecule-1 and pentraxin-3 in the gingival crevicular fluid during maxilary canine distal movement and to assess their correlation with periodontal disease, canine movement distance and orthodontic force. METHODS:Twenty-one orthodontic patients were enroled and assigned into 150 g (n=12) or 100 g (n=9) groups according to orthodontic force. The gingival crevicular fluid samples of orthodontic patients were colected before and at 4, 12, 24 hours, 7, 14 days after maxilary canine distal movement. Levels of myeloperoxidase, soluble intercelular adhesion molecule-1 and pentraxin-3 in the gingival crevicular fluid were measured and analyzed using ELISA assay. RESULTS AND CONCLUSION: During the distal movement of maxilary canine, under orthodontic force, the level of myeloperoxidase was peaked at 4 hours and then decreased, while the expression level of soluble intercelular adhesion molecule-1 was peaked at 12 hours, and then decreased. Both myeloperoxidase and soluble intercelular adhesion molecule-1 levels returned to normal at 7 days under orthodontic force. The expression level of pentraxin-3 was increased significantly under orthodontic force, peaked at 24 hours, and then decreased gradualy to the normal level at 7 days. In addition, the expression levels of myeloperoxidase, soluble intercelular adhesion molecule-1 and pentraxin-3 in the gingival crevicular fluid were significantly higher under 150 g force than under 100 g force. These findings indicate that detecting varying levels of myeloperoxidase, soluble intercelular adhesion molecule-1 and pentraxin-3 in the gingival crevicular fluid is useful to assess the efficiency of orthodontic treatment and prevent adverse reactions.
