Medical Journal of Chinese People's Liberation Army 1983;0(05):-
This paper presents the results of a mass survey for abnormal hemoglobins in Xinjiang. 117, 847 sub-jects of 21 nationalities in 31 countries (cities) were examined. Seven hundred and ten instances of abnormal hemoglobins .and thalassemias were identified. Hematological and biochemical investigations as well as clinical and family studies were carried out on 52 prebands. The overall incidence of abnormal hemo- globing was 4.23%. Altogether 17 abnormal hemoglo-bins were detected in 8 out of 21 different nationali-ties with their incidences ranging from 0.21 to 12.8%.They were mainly of the D group, which accounted for 61.3% of the total. The above results indicated that Xinjiang is one of the regions where high incid-ence of abnormal hemoglobins occurs in China with certain ethnic and geographical peculiarities. Types,distributions, clinical and genetic features of these abnormal hemoglobins were briefly discussed.

To study the expression of p63 and cyclooxygenase-2 (cox-2) in skin tumors and evaluate the correlation between p63 and cox-2, the expressions of cox-2 and p63 were measured by streptavidin-peroxidase complex immunohistochemical technique in 17 cases of skin squamous cell carcinoma (SCC), 19 cases of Bowen's disease(Bowen), 11 cases of actinic keratosis(AK), 12 cases of seborreic keratosis(SK) and 13 specimens of normal skin. Our results showed that the expression of p63 in skin squamous cell carcinoma, Bowen's disease and actinic keratosis were significantly higher than that in seborreic keratosis, while the expression of p63 in seborreic keratosis was significantly higher than that in normal skin. The expression of cox-2 in skin squamous cell carcinoma, Bowen's disease and actinic keratosis were significantly higher than that in seborreic keratosis, while no statistical difference was noted in the expression of cox-2 between seborreic keratosis and normal skin. Cox-2 expression was positively correlated with the high p63 expression in malignant skin tumors. The increased expression of cox-2 and p63 may play an important role in the development of skin tumors and work synergetically in malignant skin tumors.

In order to investigate the role of Th17 cytokines in the pathogenesis of psoriasis, reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the expression of IL-17, IL-23 (p19/p40), and IL-6 in skin lesions and non-lesions of the patients with psoriasis and skin tissues of normal subjects. The results showed that the mRNA expression levels of IL-17, IL-23p19, IL-23p40 and IL-6 in psoriasis lesion were significantly higher than those of non-lesions (1.231 +/- 0.843 vs 1.003 +/- 0.044, 1.166 +/- 0.142 vs 0.765 +/- 0.133, 1.125 +/- 0.104 vs 0.730 +/- 0.103, 1.186 +/- 0.222 vs 0.976 +/- 0.122, respectively, all P < 0.05). Meanwhile, The expression levels of IL-17 mRNA, IL-23p19 mRNA, IL-23p40 mRNA and IL-6 mRNA were higher in non-lesions than those in normal skin tissues (1.003 +/- 0.044 vs 0.620 +/- 0.104, 0.765 +/- 0.133 vs 0.584 +/- 0.078, 0.730 +/- 0.103 vs 0.000 +/- 0.000, 0.976 +/- 0.122 vs 0.656 +/- 0.121, respectively, all P < 0.05). The overexpression of Th17 cytokines in the skin lesions of patients with psoriasis may indicate that Th17 cytokines play a very important role in the immunopathogenesis of psoriasis.

To investigate the role of toll-like receptor 9 (TLR9) in the pathogenesis of lichen planus, the expressions of TLR9 and its mRNA in the lesional skin of lichen planus were detected by immunohistochemical technique (SP) and RT-PCR. As control, normal skin of healthy volunteers was also tested. The immunohistochemical study showed that the expression of TLR9 in the lesional skin of lichen planus was significantly higher than that in the normal controls. The results of RT-PCR showed that both skin lesions and normal controls had TLR9 expression. In skin lesions, the expression level of TLR9 mRNA was 1.6075+/-0.0930, which was significantly higher than that in normal controls (P<0.001). These findings indicated that up-regulated expression of TLR9 and its mRNA might be involved in the pathogenesis of lichen planus.

In order to investigate the role of MMP-9 and TIMP-1 in the pathogenesis of systemic sclerosis, the expression of MMP-9 and TIMP-1 was immunohistochemically detected in skin lesions of the patients with diffuse cutaneous systemic sclerosis, skin lesions of the patients with limited cutaneous systemic sclerosis, and skin tissues of normal subjects. The results showed that the expression of MMP-9 in lesions of diffuse cutaneous systemic sclerosis was significantly lower than that of normal skins (P<0.05). However, no significant difference in the level of MMP-9 in the limited cutaneous systemic sclerosis and normal skin was found. Meanwhile, the expression of TIMP-1 in lesions of diffuse cutaneous systemic sclerosis and limited cutaneous systemic sclerosis were significantly higher than that of normal skins (both P<0.05). It was suggested that the expression of MMP-9 and TIMP-1 might play an important role in the development of systemic sclerosis.

Objective:To compare the clinical efficacy and safety between spleen total resection splenectomy and spleen partial splenectomy in the treatment of patients with traumatic spleen rupture.Methods:84 cases of patients with traumatic spleen rupture from March 2013 to March 2016 were selected and divided into two groups.42 cases in the spleen total resection group were treated with spleen total resection,while the other 42 cases in the spleen partial nephrectomy group were treated with spleen partial splenectomy.The operative effect,the levels of platelet count,serum IgA,IgG,IgM,CD3 +,CD4 +,CD8 +,CD4 + / CD8 + levels before and after treatment,the incidence of complications were compared between two groups.Results:The intraoperative blood loss,exhaust time,length of hospital stay of spleen partial nephrectomy group were shorter than those of the spleen total resection group,but the operation time of research group was longer than that of the spleen total resection group (P<0.05).The platelet count,CD8+ of spleen partial nephrectomy group were lower than those of the spleen total resection group (P<0.05).The IgA,IgG,IgM,CD3+,CD4+,CD8+,CD4+/CD8+ of spleen partial nephrectomy group were significantly higher than those of the spleen total resection group (P<0.05).The incidence rate of complications in the spleen partial nephrectomy group was lower than that of the spleen total resection group (P<0.05).Conclusion:Spleen partial splenectomy was more effective than spleen total resection in the treatment of traumatic splenic rupture,which had little effect on the platelet and immune function.

Gene analysis of the first family with ?-thalassemia in Xinjiang was carried out by polymerase chain reaction (PCR) in combination with dot blot hybridization of allele -specific oligonucleotide (ASO) probes. Seven of the 12 family members were heterozygous for the IVS- Ⅱ-654 (C→T) mutation. The abnormal ? gene of proband was confirmed from the paternal side according to family survey, clinical syndrome and hematological data.
