Objective To analyze the dynamic changes of white blood cells in patients with cavitary pulmonary tuberculosis (CPTB) during chemotherapy procedure ,and explore immunological indexes which could evaluate the curative effect and prognosis . Methods 85 cases of patients with CPTB (CPTB group) and 100 healthy people conducted physical examination (control group) were enrolled in this study ,The immunological indexes of white blood cells were detected and compared between CPTB group and control group ,and dynamic changes of white blood cells were analyzed in patients with CPTB .Results Compared with the control group ,absolute lymphocyte count and percentage of lymphocyte were decreased in the CPTB group before chemotherapy ,while the total white blood cells count ,absolute neutrophil count and percentage of neutrophil ,absolute monocyte count and percentage of monocyte were increased in the CPTB group before chemotherapy ,there were statistically significant differences between the two groups(P<0 .05) .Except the absolute lymphocyte count ,other indexes were statistically increased or decreased during chemothera‐py procedure .Conclusion After chemotherapy ,the immunological reactions induced by lymphocyte are under inhibitory state .The dynamic changes of white blood cells could reflect the state of cellular immunity in patients with CPTB during chemotherapy ,which could be helpful for the evaluation of curative effect and prognosis .

In vitro cellular adherence of murine neutrophils (Neu), macrophages (Mo) and eosinophils (Eos) to infective larvae (L3) of periodic Brugia malayi was promoted by immune serum (AIMS) or fresh normal mice serun (fNMS). Mo and Neu were more potent than Eos . in killing the L3. Eos could adhere to the L3 in the presence of AIMS or fNMS but a weak cy-totoxic effect was observed only when AIMS was used. The activity in AIMS could be removed with Staphylococcus aureus containing Protein-A (SPA) or anti-mice IgG antiserum suggesting that IgG might be in the observed cytotoxicity. Immunofluorescent staining revealed IgG binding to the surface of L3 after incubation with AIMS. Heat treatment of AIMS at 56℃ 30 min resulted in a reduced cytotoxic effect suggesting the role of complement in the reaction. EDTA but not EGTA abolished this activity indicating the operation of complement by alternate pathway. Scanning electron microscopic (SEM) studies comfirmed that the celluar adherence resulted in gross surface damage to the infective larvae.

Objective To investigate the prevalence of dyslipidemia and overweight/obesity of residents from different economic communities.Method One thousand six hundred and twenty-three residents from three communities with different economic condition in Huadu District,Guangzhou from June to July 2012 participated in the survey by questionnaire and health examination.Results The total prevalence rate in overweight/obesity was 29.4%and that of dyslipidemia 45.4%. The difference of prevalence rate of dyslipidemia among the three economic communities was not statistically significant(P>0.05). But the prevalence of overweight/obesity was statistically significantly different among them(P<0.05). The prevalence rate of overweight/obesity in Huadong town with a relatively poorer economy was lower than that of Tianmei town with a relatively better economy(P<0.017). The prevalence rate of overweight/obesity of male among the three communities had no significant differences(P>0.05),whereas the differences in the females were statistically significant(P<0.05),and the prevalence rate of Huadong town was lower than that of Tianmei town&Xinhua town. The differences in the prevalence of overweight/obesity at different ages from all economic communities showed statistical significance(all P<0.05).The residents aged 45~65 accounted for a large proportion of overweight/obesity.Conclusions Residents in the area have a high prevalence of overweight/obesity and dyslipidemia. The prevalence rates of overweight/obesity from the villages with better economic conditions are higher than that from the villages with poorer economic conditions. Residents aged 45-65 from all the three communities have a relatively high occurrence of overweight/obesity and dyslipidemia.

[Objective]To explore the consumptive disease treating experience in Gushi Yijing, written by Gu Songyuan who lived in the Qing Dynasty. [Methods]By studying consumptive disease related content in the book, discussing and summing up the consumptive disease treating experience. [Results] On the basis of pointing out seven kinds of error method that doctor treating consumptive disease at that time, Gu Songyuan put forward the opinion that consumptive disease was usual y caused by the internal injury of Zang and Fu organs which resulted into Yin deficiency as the main pathogenesis. The article contained other details as fol ows: the basic symptoms of consumptive disease of the five internal organs, three main therapeutic methods on treatment of consumptive disease, the preference of nourishment combined drugs with food, habit of using some sweet and cold durgs which can clear heat, the use of flesh and blood of sentient beings and so on. So the key idea of this article focused on the method of nourishing Yin to enrich Jing and blood which could cure the consumptive disease effectively.[Conclusion]Gu Songyuan inherited predecessor ’s theory, analysed the etiology of consumptive disease of the five internal organs, pointed out Yin deficiency is the main pathogenesis, and then put forward the therapeutic method, which has some medical knowledge on modern clinic.

ObjectiveTo investigate the expression of psoriasin in actinic keratosis(AK),Bowen's disease and squamous cell carcinoma(SCC) tissues.MethodsImmunohistochemistry was carried out to quantify the expression of psoriasin protein in tissue specimens from the lesions of 20 patients with AK,25 patients with Bowen' s disease,21 patients with well differentiated SCC,and16 patients with poorly differentiated SCC,as well as from the skin of 18 normal human controls.ResultsThe expression rate of psoriasin was 11.1％ in the control specimens,significantly different from that in the AK(95.0％),Bowen's disease (88.0％),well differentiated SCC (95.2％),and poorly differentiated SCC (92.3％) specimens (all P ＜0.01 ).Psoriasin was expressed in the cytoplasm of keratinocytes and dyskeratotic keratinocytes in stratum corneum and upper 1 to 3 layers of stratum spinosums in AK tissue,in the cytoplasm of keratinocytes as well as the membrane and cytoplasm of vacuolated cells in all layers of the epidermis in Bowen's disease tissue.In well differentiated SCC,cornified pearl and dyskeratotic keratinocytes located in the stratum comeum and all layers of the stratum spinosums stained positive for psoriasin,and in poorly differentiated SCC,psoriasin was distributed in the stratum corneum and upper 1 to 5 layers of the stratum spinosums,but absent in poorly differentiated squamous cells.The expression intensity of psoriasin in tissues sequentially increased from AK,Bowen's disease to well differentiated SCC.Though the expression intensity of psoriasin in poorly differentiated SCC decreased,but was still higher than that in normal skin tissue(P ＜ 0.05).ConclusionPsoriasin is abnormally expressed in skin disorders with dysdifferentiation of squamous cells.

Objective To explore the risk factors of adhesive small bowel obstruction for the influence of the long-term therapeutic effects.Methods 218 case of adhesive small bowel obstruction in patients were treeted with a long follow-up and retrospective analysis.Results Among the 218 admissions in 235 patients,192 admissions (81.7.％) were surgical treated and 43 admissions(18.3％) were performed conservative treatment.The mean recovery time was 65.7 months and the accumulative incidence of surgical recurrence in 5 years was 19.0％ in surgical group and those in conservative group were 50.4 months and 34.0％ respectively.There was significant difference between two groups (P ＜ 0.05).Conclusion The long-term efficacy of risk factors was related to the treatment before the operation site and times,the last operation to the incidence of admissions.No other independent risk factor of recurrence was found.Surgical treatment serves as a better way in the prevention of later recurrences in patients with adhesive intestinal obstruction under certain conditions.

In order to investigate the application of par plana vitrectomy in the treatment of combined rhegmatogenous retinal detachment (RRD) and choroidal detachment (CD), 12 eyes of 12 cases of combined RRD and CD were retrospectively analyzed. Twelve eyes of 12 cases were subjected to par plana vitrectomy. Six mm infusion channels were used. Pars plana vitrectomy, membrane peeling and internal fluid－gas exchange with encircling scleral buckle placement were performed in a standard fashion. One patient received injection of silicone oil. Hormones were routinely administered pre- and post-operation. The results showed that the intraocular pressure was rapidly reconstructed in the 12 eyes of 12 cases, the fluid in the subchoroidal cavity was drained via the three sclera incisions. The detached choroidea replaced. No other sclera incision was needed to drain the fluid in the subchoroidal cavivity. The follow－up after operation lasted 2 to 16 months. The 12eyes were replaced anatomically. No postoperative proliferation of vitreous body and retina was induced. It was suggested that par plana vitrectomy was the first choice in the treatment of CD combined with RCD.

Objective To study the protective effect of nalmefene hydrochloride on lung ischemia-reperfusion injury and its mechanism.Methods 40 rats were randomly divided into model group,high dose of nalmefene group,low dose nalmefene group and sham operation group equally(n =10).The lung ischemia-reperfusion model was established by occlusion of the left pulmonary hilum.The intravenous injection of nalmefene (20,10 μg·kg-1) was applied at 10 minutes before occlusion of the left pulmonary hilum in the high dose of nalmefene group and the low dose of nalmefene group,respectively.The sham operation group without occlusion of the left pulmonary hilum was not given any treatment.At 2 h after reperfusion,all rats were detected arterial blood gas value and then sacrificed.The specimens from the upper lobe of the left lung tissue were preserved to observe pulmonary lesions,detect the ratio of wet / dry weight and the expressions of β-endorphin and interleukin(IL)-17.Results Compared with the model group,the value of PCO2,the degree of pulmonary lesions,the ratio of wet / dry weight and the expressions of β-endorphin and IL-17 in lung tissue were significantly decreased (P ＜ 0.01),while the value of PO2 was significantly increased (P ＜ 0.01) in the low dose of nalmefene group.Compared with the low dose of nalmefene group,thevalue of PCO2,the degree of pulmonary lesions,the ratio of wet/dry weight and the expressions of β-endorphin and IL-17 in lung tissue were significantly decreased (P ＜ 0.01),while the value of PO2was significantly increased (P ＜ 0.01) in the high dose of nalmefene group.Conclusion Nalmefene hydrochloride may prevent lung ischemia-reperfusion injury in a dose dependent manner by reducing the production of β-endorphin and inhibiting the expression of IL-17 in lung tissue.
