Objective To investigate the therapeutic effect of spleen-strengthening,lung-clearing and phlegm-resolving herbs for the treatment of acute attack of chronic obstrustive pulmonary disease(COPD) complicated with systemic inflammatory response syndrome(SIRS),and to observe their effect on nuclear factor ?B(NF-?B)expression level.Methods Sixty qualified patients differentiated as deficiency of spleen and lung,phlegm-heat accumulating the lung were equally randomized into two groups:the control group received routine western medical treatment including oxygen inhalation,antibiotics and bronchodilator,and the treatment group received Chen Xia Liujunzi Decoction and Weijing Decoction,which have the actions of strengthening spleen,clearing lung,and resolving phlegm,one dose per day,for 7 days.The changes of clinical symptoms and signs,blood gas parameters and NF-?B expression level were observed.Results After treatment,clinical symptoms and signs such as cough,expectoration,dyspnea,shortness of breath,and wheeze were relieved in both groups(P

Gene chips have been widely applied for the study of lymphoma,involvement discovering tumor-associated genes,assisting classification and investigating cell origin.So far,studies about gene chips detection mainly focus on B-cell lymphomas and T-cell lymphomas.According to those studies,traditional classifications of some kinds of lymphomas have been suspected and cell origin of some kinds of lymphomas have been suggested,which lay the foundation for further study.However,there are still somethings unknown about extranodal NK/T-cell lymphoma,more gene chip detection should be performed for further understanding of the tumor.

[Objective] To observe the influence of Modified Qianjin Weijing Decoction (MQWD) on airway clearance in patients with acutely exacerbated chronic obstructive pulmonary disease (AECOPD) , which was differentiated as the syndrome of phlegm-heat congesting lung. [Methods] A prospective control trial was carried out in 60 AECOPD patients with phlegm-heat congesting lung. The patients were equally randomized into two groups: the treatment group (group A) was treated with MQWD and routine western medicine, and the control group (group B) with routine western medicine only. The therapeutic effect, indexes of lung function including FEV1 (forced expiratory volume in one second), FVC (forced vital capacity), FEV1/FVC, Zrs (total respiratory impedance) and R5 (total airway resistance), and in particular, the airway clearance rate (Ct) were observed and compared in the two groups. [Results] In the treatment group, the markedly effective rate was 70.00 % , higher than that (23.33 % ) in the control group ( P 0.05) but Ct in 60-minute and 90-minute treatment was much improved in the treatment group than that in the control group (P

Objective To determine whether rapid and delayed tolerance to focal cerebral ischemia can be induced by pretreatment with single electroacupuncture (EA) at the Baihui acupoint in rats. Methods Forty-eight healthy male SD rats weighing 280-320 g were randomly divided into 6 equal groups with 8 animals in each group: (1) control group received no pretreatment before focal cerebral ischemia; (2) electroacupuncture group was further divided into 5 groups in which EA was performed at Baihui acupoint and electric stimulation was maintained for30min0.5 h(EAl),1 h(EA2),2 h(EA3),3 h(EA4) or 24 h(EA5) before focal cerebral ischemia. The animals were anesthetized with isoflurane and spontaneous respiration was maintained. Middle cerebral artery occlusion (MCAO) was performed using a nylon thread with a rounded tip inserted into internal carotid artery and thread cranially until resistance was felt. MCAO was maintained for 2 h, then the nylon thread was withdrawn to allow reperfusion . After MCAO the animals were observed for 24 h for neurological deficits which were assessed by a 0-5 grade scoring system (0 = no deficit, 5 = death) . The animals were then sacrificed and brain was immediately removed for estimation for the size of cerebral infarction. Results There were significantly less neurological deficits and the size of infarction was smaller in group EA3 and EA5 than those in control group. There were no significant differences in neurological deficits and size of infarction between group EA1,EA2,EA4 and control group. Conclusion Pretreatment with single electroacupuncture stimulation for 30 min at Baihui acupoint can induce rapid and delayed tolerance to focal cerebral ischemia. Rapid tolerance develops 2 h after pretreatment while delayed tolerance develops 24 h after pretreatment.

Objective To study the effect of interleukin 13(IL-13)on mucin gene Muc5ac and EGFR expression in mouse lungs. Methods Twenty-four male BALB/c mice were randomly divided into control group and different dose of IL-13 (50ng, 100ng and 250ng) groups, six mice per group. Muc5ac mRNA, and Muc5ac and EGFR protein expressions were detected by RT-PCR and immunohistochemical method, respectively. Results Both Muc5ac and EGFR positive products were located in the cytoplasm of airway epithelial cells. Compared with control group, IL-13 could increase Muc5ac mRNA, and Muc5ac and EGFR protein expressions in dose-dependent manner(all P

Ca~(2+)-activated chloride channels (CaCC, CLCA) are a new family of chloride channels discovered recently, which are related to Ca~(2+)-sensitive chloride ions transport, and there were several members identified currently in different biologic bodies. New studies have shown that its member gob-5 in murine (its human counterpart is CaCC1) plays a pivotal role in airway goblet cell metaplasia, mucus overproduction, MUC5AC gene expression as well as airway hyperresponsiveness (AHR) in asthma, and is a key molecule in the induction of murine asthma and an asthma-related gene. Inhibition of their function and/or their signaling pathway may therefore provide a new therapeutic strategy for asthma.

Objective To discuss the microsurgery approaches and the prevention and treatment of complication about the tumors in cerebellopontine angle.Methods The 53 cases with cerebellopontine angle brain tumor were retrospectively analyzed.Results In all 53 patients,the tumor of 23 cases were full-resected,29 cases' tumor were resected more then 3/4,only one cases' tumor was partly treated.Following operation,one case died,5 cases had hearing decreasing,3 cases had severely facial nerve weakness and non hearing,10 cases had facial nerve anaesthesia,futhermore there was one case with long-period coma because of the injury of brain stem.Conclusion The important factors that decrease the complications of cerebellopontine angle tumor surgery include surgery approachs,operating experience and mechanism of complication.

Objective To explore the effect of operative treatment of hypertensive intracerebral hemorrhage.Methods 386 cases with hypertensive intracerebral hemorrhage were retrospectively analysed,hematoma was removed through big bone flap and small skull window,or drainage and urokinase infusion with small hole puncture.Results 39 cases died(10.1%),according to ADI grade system:Ⅰ 106 cases(27.4%),Ⅱ 136 cases(35.2%),Ⅲ 50 cases(13%),Ⅳ 43 cases(11.1%),Ⅴ 12 cases(3.2%).Conclusion To increase the cure rate and life quality,and obtain a lower mortality,it is a key to do surgical operation such as microsurgery or drainage and urokinase infusion.

Objective To explore the complications of augmentation mammoplasty by polyacrylamide hydrogel (PAHG) injection and their management.Methods Preoperatively,174 patients underwent breast ultrasound image,and some patients received magnetic resonance imaging (MRI) to ascertain the distribution of injected PAHG.We used the periareolar incision and dissection extended to the subcutaneous tissue,mammary gland,and subgland space.We were able to suck most of the gel by the negative pressure machine and remove the abnormal breast tissue.The secondary breast deformity was repaired with subpectoral placement of silicone mammary implants (48 cases immediately,39 cases secondarily after 3-6 months) according to the individual situation.Results Following-up for 3 to 6 months,most of their symptoms were relieved after removal of the polyacrylamide hydrogel.In the patients who were performed with the implants augmentation mammoplasty,77 cases gained satisfactory results on the shape and texture of the breast (44.3％),and 10 cases were not satisfied with texture of the breast (5.7％).79 cases appeared breast atrophy or flat chest (45.4％).The severe breast deformities occurred in 8 cases (4.6％).Conclusions PAHG should be removed with surgical operation as soon as possible.The open operative technique via periareolar incisions may be a better method for the patients.The breast reconstruction is performed with implants prosthesis for those who are suitable and willing after removal of PAHG.
