OBJECTIVETo observe preventive and therapeutic effect of Yifei Jianpi Recipe (YJR) on chronic obstructive pulmonary disease (COPD) model rats and to explore its mechanism from the way of airway inflammation and airway mucus hypersecretion.

METHODSThe COPD rat model was established by using cigarette smoking combined with intratracheal injection of lipopolysaccharide (LPS). Male SD rats were randomly divided into the blank control group (control group), the model group, the YJR group, 6 in each group. Forced vital capacity (FVC), forced expiratory volume in 0. 1 second (FEV0. 1), FEVO. 1/FVC, peak expiratory flow (PEF) was tested by lung function device. Pathological changes of bronchi and lung tissues were observed by HE staining. Airway Goblet cells were observed using AB-PAS staining. Contents of IL-8, IL-17, and TNF-α in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay (ELISA). Protein expressions of intercellular cell adhesion molecule-1 (ICAM-1), nuclear factor KB (NF-KB), mucin 5AC (Muc5AC), and Toll-like receptor 4 (TLR4) in rat airway were detected by immunohistochemical assay. mRNA expressions of TLR4 and Muc5AC in bronchi and lung tissues were detected by real-time quantitative PCR (RT qPCR).

RESULTSChanges of bronchi and lung tissues in the model group rats were consistent with typical pathological manifestations of COPD. Compared with the model group, the degree of lung injury was significantly alleviated in the YJR group. Compared with the control group, FVC, FEV0. 1, FEVO. I/FVC, and PEF were decreased (P <0. 01), contents of IL-8, IL-17, and TNF-α in BALF were significantly increased (P <0. 01), protein expressions of ICAM-1, NF-KB, Muc5AC, and TLR4, mRNA expression levels of Muc5AC and TLR4 in bronchi and lung tissues were also significantly increased in the model group (P <0. 01). Compared with the model group, FVC, FEV0. 1, FEV0. 1/FVC, and PEF were significantly increased in the YJR group (P <0. 01, P <0. 05), but the rest indices were significantly lowered (P <0. 01, P <0. 05).

CONCLUSIONYJR could decrease contents of IL-8, IL-17, and TNF-α in BALF of COPD model rats, inhibit protein expression levels of ICAM-1, NF-κB, Muc5AC, and TLR4.in airway and lung tissues, thus playing preventive and therapeutic roles by reducing airway inflammation and airway mucus hypersecretion.

Objective To explore the effect of reduced glutathione and venous systemic oxygen perfusion on apoptosis and ultrastructure of hepatocytes in rat steatotic liver grafts. Methods Before liver transplantation grade Ⅱ steatotic liver model was established by a diet consisting of 79% standard diet,20% lard and 1% cholesterol for 6 weeks. In pretreatment group, the donor received intraperitoneal injection of reduced glutathione at a dosage of 500 mg/kg/body weight 3 times a day for 2 days, and intrahepatic venous oxygen perfusion for 6 hours while kept in cold preservation. Results Preconditioning measures in steatotic liver grafts significantly decreased the hepatocytes necrosis (38?10)% vs (17?6)%, P

Objective To report the experience of using rectus abdominis musculocutaneous flap after open-window thoracosto- my in managing refractory chronic pleural empyema.Methods From Nov.2004 to Mar.2006,intrathoracic transplantation of the musculocutaneous flap was performed successfully in 4 patients with empyema and fistula after upper lobectomy.The myocutaneous flap was designed in such a way that epigastrica vessels were incorporated.Results The rectus abdominis myocutaneous flap has provided sufficient bulk for tract obliteration.Over a mean follow-up period of 10 months,patients are free from recurrent infections and skin nacrosis.Conclusion Vaseularized museulocutaneous flap may help in healing refractory empyema.

Objective:To observe the clinical efficacy of acupuncture at abdomen acupoints plus tuina for lumbar intervertebral disc herniation (LIDH).Methods:A total of 70 patients with LIDH were randomized into an observation group and a control group,with 35 cases in each group.The observation group was treated with acupuncture at abdomen acupoints plus tuina,while the control group was treated only with tuina treatment.The clinical efficacy was observed after one course of treatment.Results:The cure rate and the total effective rate of the observation group were 83.3％ and 96.7％,respectively.The cure rate and the total effective rate of the control group were 39.4％ and 78.8％,respectively.There were significant differences in the cured rate and the total effective rate between the two groups (both P＜0.05).There was no significant difference in Japanese Orthopedic Association (JOA) score between the two groups before treatment (P＞0.05).After treatment,the JOA scores of both groups increased significantly,and the intra-group differences were statistically significant (both P＜0.05);the JOA score of the observation group was significantly higher than that of the control group (P＜0.05).Conclusion:Acupuncture at abdomen acupoints plus tuina has a better therapeutic effect than tuina alone in the treatment of LIDH.

Objective To observe the clinical efficacy of warm needling at Yintang (GV 29) plus ginger-partitioned moxibustion in treating allergic rhinitis.Method Seventy patients with allergic rhinitis were randomized into a treatment group and a control group,35 cases each.The treatment group was intervened by warm needling at Yintang (GV 29) plus ginger-partitioned moxibustion;the control group was treated with conventional medication.After 4-week treatment,the clinical efficacies of the two groups were compared.Result The markedly effective rate and total effective rate were respectively 83.9％ and 96.8％ in the treatment group,versus 56.3％ and 75.0％ in the control group,and the between-group differences were statistically significant (P＜0.05).Conclusion Warm needling at Yintang (GV 29) plus ginger-partitioned moxibustion is an effective approach in treating allergic rhinitis.

OBJECTIVETo study clinic therapeutic effect about reconstruction of severe orbital and cul-de-sac deformity after the radiotherapy with transcranial orbitotomy advancement combining cascade free flap both dorsum pedis flap and anterior tibial fascial flap.

METHODSFive cases was subjected to orbital and cut-de-sac severe deformities after both operation and radiotherapy because of retinoblastoma. The technique included transcranial orbital advancement by anterior orbital osteotomy and rigid fixed with titanic plate by coronal incision, and meanwhile incising the cul-de-sac which would be extended circumference around the central incision separation, and then designing extent of cascade flap consisted of dorsum pedis flap and anterior tibial fascial flap according to the size of cul-de-sac defect and extent of temporal depression. Then, the aforementioned two parts of cascade flap were transplanted into cul-de-sac and temple respectively. There is either the superficial temporal artery and vein or facial artery and jugular vein to chose vascular anastomosis.

RESULTSAll flaps survived. After 3 to 6 months following up, the results showed satisfactory orbital contour and temporal depression improved significantly in all cases. After the conjunctival sac were fixiformed with prefabricated eye prosthesis mode about 3 months. 3 cases have good appearance with wearing eye prosthesis and the other 2 cases' appearance is poor. One of the poor appearance cases, with depressed eye socket, have orbital implant underlying conjunctival sac in secondary operation. The other one, with swallowed inferior fornix, is transplanted autogenous hard palatal mucosa into inferior fornix in secondary operation. In addition, delayed healing in donor site of dorsum pedis occurred in one of the 4 cases.

CONCLUSIONSIt is a reliable procedure about reconstruction of severe orbital and cul-de-sac deformity after both the operation and radiotherapy with transcranial orbitotomy advancement combining cascade free flap both dorsum pedis flap and anterior tibial fascial flap. All deformity was corrected by one staged procedure which lessen patient's suffering and shorten patient's hospital stay and spare patient's costs.
