Objective To study the distribution of IL-10 and TNF gene polymorphisms in patients with gastroduodenal diseases in Hubei Han ethnic and their association with Helicobacter pylori (Hp) infection. Methods Six hundred and five patients with gastroduedenal diseases (196 chronic gastritis, 189 gastroduodenal ulcer and 220 gastric cancer) as well as 624 healthy controls were genotyped with PCR-RFLP method for IL-10-1082,-819,-592 and TNFα-308, lymphotoxin-α (LTα) Nco Ⅰ and AspH Ⅰ gene polymorphisms. Hp infection status was determined with ELLS& Results (1) There was significant difference of IL-10-1082 AG + GG genotype among the gastric cancer group with the non-malignant gastric diseases groups and healthy control group (P <0. 05). There was no significant difference of IL-10-592 and -819 gene polymorphisms among gastric cancer patients,non-malignant gastric disease patients and healthy controls (P>0. 05). The genotype frequencies of IL-10-819 were the same as those of IL-10-592. (2) Frequency of IL-10-1082 AG + GG genotype in gastric cancer patients with positive Hp was significantly higher than that in the other three groups (P < 0. 05). (3) Frequency of LTα Nco I AG genotype in gastric cancer patients with Hp infection was signiilcandy higher than that in Hp positive healthy controls (P < 0. 05). There were no other associations between TNFα-308, LTα Nco Ⅰ and AspH Ⅰ gene polymorphisms and Hp infection in gastroduodenal diseases. Conclusions (1) Allele AG + GG of IL-10-1082 was associated with gastric cancer in Han nationality of Hubei province. (2) IL-10-1082 AG + GG,LTct Nco ⅠAG heterozygous genotype may be associated with Hp infection in patients with gastric cancer in Han nationality of Hubei province.

Objective To observe the effect of using Ambroxol hydrochloride(AM)to wash respiratory way to treat neonatal respiratory distress syndrome(NRDS) in ventilator,to explore dynamic changes of respiratory mechanics after using AM to wash respiratory way.Methods Thirty premature infants were chosen according with diagnosis criterion,which were randomly divided into 2 groups: NS group(n=15);AM group(n=15).Both NS and AM groups were treated with Babylog 8 000 ventilator,and routine treating and nursing,NS group was given for washing respiratory way in NS group,whereas AM was done in AM group.Pulmonary compliance(C),time constant(Tc),respiratory resis-tance(R),C20/C and minute volume(MV)were observed in both groups.Blood gas was routinely checked after 1 h ventilation treatment,and X ray was shot after 24 h.Results Pulmonary C significantly increased in weaning than that of beginning ventilation(P0.05),MV significantly increased in group AM than NS,respectively[(0.56?0.12) L/min and(0.35?0.11) L/min(P0.05).But ventilator-treating-time was markedly shorter in group AM than NS,respectively(60.52?6.23) h and(98.21?5.82) h(P

Objective: This study was designed to evaluate the therapeutic efficacy of bronchial arterial infusion with VDS＋ DDP or MMIC＋ ADM＋ DDP in patients with locally advanced nonsmall cell lung cancer(NSCLC). Methods: From June 1992 to October 1998,102 patients with locally advanced NSCLC were enrolled in this study. Of them,8 cases in Stage Ⅱ , 72 cases in Stage Ⅲ a, 22 cases in Stage Ⅲ b, central type: 75 cases,peripheral type:27 cases;preliminary group 64 cases, secondary group 38cases. The patients were treated one to four times by bronchial arterial infusion of the chemical drugs Results: There were 3 complete responses and 66 partial responses for an overall responses rate of 67.65％ (69/102) including responses rate of 72.00％ (54/75) in central type and 55.56％ (15/27), the 1-year and 2-years survival rate was 67.64％ (69/102)and 36.28％ (37/102) respectively. Conclusions: The therapeutic efficacy of bronchial arterial infusion with chemical drugs was excellent to locally advanced non small cell lung cancer, it′ s toxicity were acceptable. The efficacy on central was much better than for peripheral type

OBJECTIVETo study diffuse alveolar hemorrhage (DAH) in patients with hematologic malignancies after chemotherapy and discuss the possible etiology and appropriate therapy.

METHODSSymptoms, physical examinations, laboratory examination, chest radiographs or computed tomographic (CT) scans, treatments and outcomes of two patients with acute lymphoblastic leukemia (ALL) and non-Hodgkin lymphoma (NHL) each after chemotherapy were presented.

RESULTSBoth of the patients developed cough, progressive dyspnea, a drop of hemoglobin level, hypoxemia and widespread pulmonary infiltrate on chest radiographs or CT scans after chemotherapy. Moreover, case 1 (ALL) had high fever and bloody fluid drained from the intubation of mechanical ventilation, case 2 (NHL) developed continual hemoptysis. They were diagnosed as DAH and improved significantly after intermediate- or high-dose corticosteroid therapy.

CONCLUSIONSDAH is a rare fatal acute noninfectious pulmonary complication in patients with hematologic malignancies after chemotherapy. Early accurate diagnosis, identifying the underlying cause and appropriate treatment are critical for the management of DAH.

OBJECTIVE To investigate the risk factors,clinical characteristics and resistance of Staphylococcus aureus nosocomial infections so as to guide the treatment of S.aureus infection.METHODS To collect clinical materials of S.aureus nosocomial infection and analyze risk factors and clinical characteristics and detect sensitivity of isolated strains to antibacterial agents.RESULTS Severe underlying diseases existed among 73 cases of S.aureus nosocomial infections,82.19 percent of patients had received invasive interventions.Lower respiratory tract was the most common infective site.Seventy-nine strains of S.aureus were isolated,including 66 meticillin-resistant S.aureus(MRSA) and 13 meticillin-sensitive S.aureus(MSSA).S.aureus showed general resistance to many kinds of antibiotic drugs.The resistant rates of MRSA were much higher than those of MSSA(P

0.05), especially the survival rate of stage ⅢA disease.Conclusions Concurrent chemoradiotherapy seems to be better than the sequential counter part for NSCLC,without 3 increasing the toxicity.

AIM: To evaluate the safety, efficacy and stability of posterior chamber phakic intraocular lens ( ICL ) implanation and clear lens extraction for the correction of high myopia.
METHODS: The study enrolled 56 cases ( 100 eyes ) of high myopia. Group I comprised 32 cases ( 58 eyes ) receiving ICL implantation and Group II comprised 24 cases (42 eyes) undergoing clear lens extraction. In this study, we evaluated the two groups of subject's the visual and refractive results, intraocular pressure ( IOP ) , endothelial cell density ( ECD ) , anterior chamber depth ( ACD) , lens transparency, the surgical complications as well as visual adverse symptoms before and after surgery.
RESULTS: The postoperative subjects in group I and group II were followed, uncorrected vision acuity ( UCVA)>0. 5 were 69. 0% in group I and 71. 4% in group II after 3mo. UCVA>0. 5 were 72. 4% in group I and 73. 8% in group II after 1a. Predictability of the manifest spherical equivalent refraction within±1. 00D was achieved in 62. 1%of eyes in group I and 57. 1% in group II after 1a. The central vault of the ICL ( distance from posterior surface of ICL to the crystalline lens ) measured with anterior segment optical coherence tomography ( AS-OCT ) was 0. 35-0. 54 (0. 40±0. 16) mm. Twelve point one percent of eyes in group I and 7. 1% of eyes in group II had transient mild increase in IOP. Here were statistically significant differences between preoperative and postoperative ECD (P<0. 001 ). Complications of surgery: 1 eye had ICL spontaneous rotation, 2 eyes had anterior subcapsular cataract, 4 eyes noticed halos around lights at night in group I. Three eyes had posterior capsule mild opacification, 3 eyes noticed halos around lights at night, 12 eyes had difficulty in near vision in group II.
CONCLUSION: ICL implantation and clear lens extraction are effective, safe and predictable surgical option for the management of high myopia. No severe complications occurred, but its long time effect and safety still need more time to prove.
