Objective To investigate behavior,knowledge and attitude of cigarette smoking,and their relationship among different occupational population in Jiangsu Province.Methods Convenient sampling was used to interview 516 staff from medical institution,schools,government offices,public transportations and waiting rooms,restaurants and internet bars.The content of interview included current smoking,second-hand smoking,and related knowledge and attitude.Results Proportion of current smoking in male(51.2%)was higher than that in female(0.3%,P90%),while it's relatively lower in "second-hand smoking and exact related diseases"(

Objective To investigate the changes of calcium /calmodulin - dependent protein kinase Ⅱ (CAMKⅡD) gene expression in 3T3 - L1 preadipocyte diffe-rentiation and TNF - ? regulation of CAMKⅡD gene expression on matured adipocytes. Methods 3T3 - L1 preadipocytes were cultured and differentiated into adipocytes. The levels of CAMKⅡD gene mRNA expression at various times were evaluated by RT-PCR. Matured adipocytes were interfered with 0.1,1.0,10.0 ?g/L TNF - ? and the levels of CAMKⅡD gene mRNA expression were evaluated. Results The levels of CAMKⅡD gene mRNA expression in 3T3 - L1 adipocytes were significantly down- regulated at first day, compared with those at zero day (P0. 05). CAMKⅡD gene mRNA expression decreased significantly at 12 hours after treatment with 10.0 ?g/L TNF-?, treatment of matured adipocytes with TNF - ? did not have any regulation role on it. Conclusions CAMKⅡD gene is involved in the differentiation of adipocytes and related to the etiology of obesity. The changes in the level of CAMKⅡD gene mRNA expression during 3T3 - L1 preadipocyte differentiation may contribute to the differentiation and adipogenesis of adipocytes. It seems that TNF - ? does not have any regulation role on the expression of CAMKⅡD genes.

Objective To investigate the effect of microcireulation blood flow and altering immunity by Chuanxiongqin,ulinastain and thymosin α1 on sepsis patients.Methods 90 patients were randomly divided into 3 groups(n=30),namely ICU group,Chuanxiongqin group,ulinastain and thymosin α1 group.HLA-DR/CD14+and IL-6,TNF-α,Lac,DD were measured.Results (1)DD showed no significant difference at every time point between ICU group and ulinastain+thymosin α1 group(P＞0.05).DD decreased in Chuanxiongqin group,and was significantly different from the others on the third day.(2)Lac unchanged significantly at every time point in ICU group(P＞0.05).Lac in Chuanxiongqin group and ulinastain+thymeain α1 group tended to decrease,and was statistically different from ICU group on the second day.(3)IL-6 and TNF-α tended to increase at every time point in ICU group(P＜0.05).In ulinastain+thymosin α1 group,IL-6 and TNF-α returned to the level before treatment,HLA-DR/(D14+increased significantly,and was higher than Chuanxiongqin group and ICU group statistically.Conclusion Chuanxiongqin could ameliorate circulation;ulinastsin and thymosin α1 could depress IL-6,TNF-α.So ulinastain and thymosin α1 might protect the immunity of sepsis patients.

Objective:To investigate the clinical features, the key point of diagnosis and treatment methods of X-linked hyper-IgM syndrome (XHIGM).Methods:The clinical characteristics and laboratory data of a patient aged 23 years who was diagnosed as XHIGM complicated with T-cell large granular lymphocytic leukemia (TLGLL) in Institute of Hematology & Blood Diseases Hospital in March 2020 were analyzed retrospectively, and the literatures were reviewed.Results:This male patient presented with recurrent infection when he was 17 years old, and was found neutropenia, anemia accompanied by obvious splenomegaly, lower level of IgG and IgA after the visit. The level of IgM was lower than the normal level and the typical XHIGM was manifested with the normal or increased level of IgM, however CD40L homozygous mutation (chromosome: chrX; location: 135730438; variation of amino acid: NM_000074:exon1:c.31C>T:p.R11X; nonsense mutation) was confirmed by next generation sequencing. CD40L heterozygous mutation was detected in his mother, but it was not in his father. The patient was diagnosed as XHIGM. Anemia and neutropenia were alleviated after splenectomy in the patient, who was diagnosed as T-cell large granular lymphocyte elevation and clonal proliferation by flow cytometry, TCR gene rearrangement positive and bone marrow histopathological immunohistochemistry results because of the increasing leukocyte. The patient was eventually diagnosed as XHIGM complicated with T-LGLL.Conclusions:A small number of patients with XHIGM may develop symptoms in adulthood and may present with atypical clinical features of significant reduction in IgG, IgA, and IgM. The confirmed diagnosis of XHIGM is established by identification of CD40L gene mutation. XHIGM gene screening is required in male patients with recurrent infection, IgG level lower than normal and neutropenia. A few XHIGM patients are complicated with T-LGLL.

OBJECTIVETo analyze the genetic polymorphism, distribution of haplotypes, common and well-documented (CWD) and rare alleles of high-resolution HLA-A, B and DRB1 alleles by analysis from hematopoietic stem cell (HSC) donors in Jiangsu Han Chinese.

METHODSPCR-sequence-based typing and PCR-sequence specific oligonucleotide probes methods were applied for HLA-A, B and DRB1 high-resolution genotyping of 3238 unrelated healthy donors of hematopoietic stem cells in Jiangsu branch of Chinese National Marrow Donor Program registry.

RESULTS46 alleles of HLA-A,85 HLA-B and 51 HLA-DRB1 locus were found. The frequencies of the most common alleles were A * 11:01 (16.52%), B * 13:02 (11.60%) and DRB1 *07:01 (15.78%). That of the most common haplotype was A * 30: 01-B * 13: 02-DRB1 * 07: 01 (8.87%). 40 alleles of HLA-A,77 alleles of HLA-B, and 47 HLA-DRB1 alleles of HLA-DRB1 were CWD, which account for 99. 8% of total number of samples, and a few rare alleles not reported in Chinese population were found.

CONCLUSIONThe results of high-resolution, CWD and rare alleles showed the characteristics of HLA distribution in Jiangsu Han population, which may be useful for finding HLA matched unrelated donors, as well as for HLA correlation with population genetics and disease association studies.

OBJECTIVETo explore the effect of berberine on lipid metabolism disorder and lipid deposition in liver cells of non-alcoholic fatty liver disease (NAFLD) rats induced by high fat diet.

METHODSAfter one week adaptable feeding, 45 SPF level male SD rats were randomly divided into 3 groups, the normal control group, the model group, and the berberine group, 15 in each group. Except those in the normal control group, all rats were fed with high fat diet to prepare NAFLD model. As for rats in the berberine group, Berberine Hydrochloride was administered by gastrogavage. HE staining and oil red O staining were performed to identify the model after 8 weeks. Hepatocytes were isolated, and their activities and purities were tested by Typan blue staining and flow cytometry (FCM). Serum levels of TC, TG, HDL-C, and LDL-C were detected using automatic biochemical analyzer. mRNA expression levels of LXRα and FAS in liver cells were analyzed by Real-time quantitative polymerase chain reaction (PCR). Protein levels of LXRα and FAS in liver cells were examined by Western blot.

RESULTSThe NAFLD rat model was successfully established by high fat diet. The yields of purified liver cells in each rat were (6.0-7.5) x 10(8). The viability of isolated liver cells with purity over 90% (tested by FCM analysis) was higher than 95%. Compared with the normal control group,the expression of LXRα and FAS at mRNA and protein levels was higher in the model group (P < 0.01). Compared with the model group, the expression of LXRα and FAS at mRNA and protein levels was obviously down-regulated in the berberine group (P < 0.01).

CONCLUSIONSLXRα/FAS signaling pathway was one of important signaling pathways of NAFLD lipid metabolism disorders. Berberine could recover hepatocyte fatty deposits in NAFLD rats by adjusting the LXR/FAS signaling pathway of hepatocytes, which might be one of important mechanisms for fighting against NAFLD.

OBJECTIVETo study the effect of osthole (Ost) on adrenocortical function in Y1 mouse adrenocortical tumor cells.

METHODSY1 mouse adrenocortical tumor cells were taken as subjects in this experiment. In 10.0%, 1.0%, and 0.1% serum DMEM-F12 medium, Y1 cells were treated with 1, 10, 25, 50, 100, and 200 micromol/L Ost for 24 and 48 h. 0.1% Dimethyl Sulfoxide (DMSO) was taken as negative control group and 1 mmol/L (Bu) 2cAMP as positive control group. Cell growth morphology was observed under inverted microscope. Contents of corticosterone were tested by ELISA. Expression levels of steroids synthase such as Star, Cyp11a1, Cyp21a1, Hsd3b2, Cyp11b1, Cyp11b2, Cyp17a1, and Hsd17b3 mRNA were detected by Real time quantitative PCR (RT-qPCR).

RESULTSY1 cell proliferation was obviously inhibited by 100 and 200 micromol/L Ost, and its inhibitory effect was more significant in 0.1% serum medium. Compared with the negative control group, gene expressions of Star, Cyp11a1 , Cyp21a1, Hsd3b2, Cyp11b1, Cyp17a1, and Hsd17b3 were significantly enhanced in the posi- tive control group (P < 0.05). Y1 cell corticosterone levels significantly increased in 50 micromol/L Ost treatment group after 24-and 48-h intervention (P < 0.05). Contents of corticosterone increased more obviously in 25 and 50 +/- mol/L Ost treatment groups after 48-h intervention, as compared with 24-h intervention (P < 0.01). After 24-h intervention, expression levels of Star, Cyp21a1, and Hsd3b2 genes were significantly up-regulated in 25 and 50 lLmol/L Ost groups (P < 0.05). Star gene expression was further enhanced after 48-h intervention (P < 0.05). However, Ost showed no effect on Cyp11a1 (P > 0.05). Additionally, gene expressions of Cyp11b1 and Cyp17a1 were significantly enhanced by 10, 25, and 50 pLmolIL Ost after treatment for 24 and 48 h (P < 0.05). Ost showed no obvious effect on Cyp11b2 and Hsd17b3 expressions.

CONCLUSIONOst could regulate adrenal cortex function and promote corticosterone synthesis and secretion through strengthening gene expressions of steroidogenic enzymes.

OBJECTIVETo investigate the surgical outcomes of unilateral lumbar pedicle screw fixation and intervertebral body fusion in treating far lateral lumber disc herniation.

METHODSFrom June 2007 to June 2009, 25 patients with far lateral lumbar disc herniation were treated with unilateral lumbar pedicle screw fixation and intervertebral body fusion. There were 12 males and 13 females,which ranged in age from 37 to 68, with an average of 54.6 years. The course of disease was from 3 to 36 months with an average of 8.8 months. All the patients had pain and/or numbness and/or soreness in front and/or the back of unilateral leg and buttocks; muscle strength, sensation and tendon reflexes had declined of different degrees. Lumbar CT or MRI showed far lateral lumbar disc herniation. Neurological function and lumbar function were respectively evaluated according to JOA 29 score system (including subjective, objective symptom and bladder function) and Oswestry disability index (ODI).

RESULTSAll the patients were followed-up from 12 to 36 months with an average of 24 months. Postoperative wound healed well and no perioperative complications and follow-up complications were found. Neurological function of patients obtain recovery of difference degrees. At final follow-up, JOA score and ODI improved compared with that of preoperative data (P < 0.01); the mean improvement rate of JOA score was 94.3%. All patients got good bone fusion and no recurrence cases were found.

CONCLUSIONUnilateral lumbar pedicle screw fixation and intervertebral body fusion could increase the initial stability after fusion, restore and maintain the intervertebral height, and elevate the improvement rate in treating far lateral lumber disc herniation. The surgical method is safe, effective and reliable, but need to strictly control indications.
