Objective To observe the outcomes of satellite ganglion block(SGB)via posterior edge of stcmoclcidomastoid approach.Methods SGB was performed in 2 400 patients,who wererandomly divided into two groups with l 200 cases each.The puncture of SGB in group SPA was via posterior edge of sternocleidomastoid approach and that in group TPA via traditional paratracheal approac}L The same local anesthetics was used in two groups.The success rate(Horner'S syndrome appearance)and complications were compared.Results The success rate was higher in group SPA than that in group TPA(97% VS.92%)(P<0.05).Repeated puncture was needed in 16 cases ingroup SPA,which were less than 98 cases in group TPA(P<0.05).Laryngeal nerve block wasoccurred in 24 cases in group SPA.which were less than 37 cases in group TPA(P<0.05).Conclusion Compared to the traditional paratracheal approach,SGB via posterior edge ofsternocleidomastoid approach has the advantages of clear positioning,easy puncture,higher success rate and less complications.

AIM: To investigate atypical protein kinase C(aPKC), extracellular signal regulated kinnase (ERK) regulating NF-E2-related factor 2 (NRF2)-?-gutamylcysteine synthetase (?-GCS) and the effect on lung of rats with chronic obstructive pulmonary disease (COPD). METHODS: The rat COPD model was established by intratracheal instillation of lipopolysaccharide twice and exposure to cigarette smoke daily. The ?-GCS activity was measured. The expression of ?-GCS mRNA in lung tissue was examined by in situ hybridization (ISH) and reverse transcription-polymerase chain reaction (RT-PCR). The protein expressions of p-aPKC?/?, p-ERK, NRF2 and ?-GCS in lung tissue were detected by immunohistochemistry (IH) and Western blotting, respectively. RESULTS: (1) The ?-GCS activity was higher in COPD group than that in control group. (2) The expression of ?-GCS mRNA in the COPD group was stronger than that in control group. ISH showed that the ?-GCS mRNA was expressed in alveolar epithelium and bronchiolar smooth muscle cell in the COPD group. (3) The protein expressions of p-aPKC, p-ERK, NRF2, ?-GCS were significantly higher than those in control group. IH showed that p-aPKC, p-ERK, NRF2, ?-GCS proteins were expressed in alveolar and bronchiolar epithelium in the COPD group. (4) There was a positive correlation between NRF2 and ?-GCS. ?-GCS mRNA, p-aPKC?/?, p-ERK were also positively correlated with NRF2. CONCLUSION: By upregulating the signal transduction of NRF2-?-GCS, the ERK and aPKC?/? may play an important role in the mechanism of COPD formation.

Objective To research the effect of the Kiss-1 gene promoter methylation on the Kiss-1 gene expression in colorectal carcinoma tissue,and to analyze the relationship between the Kiss-1 gene methylation and the clinical pathological features of colorectal carcinoma and its clinical significance.Methods The Kiss-1 gene promotor region methylation,Kiss-1 gene mRNA and protein expressions were detected respectively by methylation-specific PCR, Real-time PCR and Western blotting method in 126 cases of colorectal carcinoma tissue and para-cacinoma normal colorectal tissue.Results The positive rate of Kiss-1 gene methylation in colorectal carcinoma tissue (83.33%)was significantly higher than that in normal tissue (30.16%)(P<0.05).In the cancer tissue,the expression levels of Kiss-1 gene mRNA and protein in Kiss-1 gene promoter methylation positive group was lower than that in Kiss-1 gene promoter methylation negative group (P < 0.05 ). The positive rate of Kiss-1 gene promoter methylation in T3+T4 stage group was higher than that in T1+T2 stage group (P<0.05),but the Kiss-1 gene mRNA and protein expression levels were lower than those in T1+T2 stage group (P<0.05).In the poorly and moderately differentiated group,the positive rate of Kiss-1 gene promoter methylation was higher than that in well differentiated group (P<0.05 ), but the mRNA expression level of Kiss-1 gene was lower than that in well differentiated group (P<0.05 ). In lymph node metastasis group, the positive rate of Kiss-1 gene promoter methylation was higher than that in lymph node negative group (P<0.05),but the mRNA and protein expression levels were lower than those in lymph node negative group (P<0.05 ). And the positive rate of Kiss-1 gene promoter methylation in distant metastasis group was higher than that in non-distant metastasis group (P<0.05), but the mRNA and protein expressions levels were lower than those in non-distant metastasis group (P<0.05). There were no significant associations between the positive rate of Kiss-1 gene promoter methylation and the gender, age,tumor location, and tumor diameter of the patients (P>0.05 ). Conclusion The Kiss-1 gene promoter methylation in colorectal carcinoma tissue is associated with the Kiss-1 gene expression level and the malignant characteristics of colorectal carcinoma;Kiss-1 gene promoter methylation may be used as a reference indicator for predicting the risk of metastasis of colorectal carcinoma.

Objective To understand the condition of anxiety and analyze the influencing factors related to anxiety among nurses working in department of infectious diseases.Methods 206 nurses from 6 third class hospitals in Wenzhou were selected by simple random sampling method.A survey was carried out by using the socio-demo-graphic information questionnaire,working conditions questionnaire,self-rating anxiety scale and social support rating scale.Results The SAS score among nurses ranged from 36 to 72 points,and the average score was (48.32 ± 12.06)points,which was higher than the norm SAS value(t=14.39,P<0.01).The percentage of anxiety was about 55.33%.The percentage of moderate and severe anxiety was 16.51%.The main factors related to the anxiety among nurses were age(t=11.34,P<0.01),working years(t=5.68,P<0.01),moonlit night shift(t=4.42,P<0.05), worrying about making mistakes(t=7.18,P<0.01),worrying about occupational exposure(t=19.93,P<0.01) and nursing management of much criticism(t=5.68,P<0.01).Conclusion The condition of anxiety was serious among nurses working in department of infectious diseases.Interventions should be taken to reduce the anxiety level among nurses.

OBJECTIVETo observe the effect of anisodamine (Ani) injection on the survival rate and histologic result of flaps with ischemia-reperfusion injury, so as to demonstrate the protective effect of Ani on the flap survival.

METHODSA total of 48 healthy male Wistar rats were randomly divided into model control, normal saline(NS) and anisodamine groups, with 16 rats in each group. An 3 cm x 6 cm axial flap was formed at the right lower abdomen with abdominal superficial blood vessel as the pedicle. 0.5 cm x 0.5 cm skin tissue was taken from the middle part of flaps in each group, immediately after operation, 12, 18, 24 h after operation. The superoxide dismutase (SOD), nitric oxide (NO), nuclear factor-kappaB contents in the specimens were detected. The histologic study was also performed. The flap survival rate was recorded 7 days after operation.

RESULTSFlap survival rate was (78.6 +/- 7.3) % in Anisodamine group. 12, 18, 24 h after reperfusion injury, the SOD was (103.3 +/- 3.9), (82.6 +/- 3.8), (67.5 +/- 4.6) U/mg; the NO was (5.33 +/- 2.05), (4.75 +/- 1.68), (4.15 +/-1.59) nmol/mg; the NF-kappaB was 0.211 +/- 0.039, 0.313 +/- 0.033, 0.096 +/- 0.028. The contents of SOD, NO and NF-kappaB had the statistical difference of at different time. The skin pathological changes in Anisodamine group was obviously better than those in NS group. Flap survival rate in Anisodamine group was significantly higher than that in NS group.

CONCLUSIONSIn the flap with ischemia-reperfusion injury, Anisodamine can reduce the damage of free radical, increase the blood flow, reduce the production of NF-KB, decrease inflammatory reaction. So Anisodamine can increase the survival rate of flaps with ischemia reperfusion injury.

Objective To observe the histopathologic and ultrastructural characteristics of cornea and adjacent conjunctiva in Mooren’s ulcer. Methods The samples of limbal and central cornea and adjacent bulbar conjunctiva taken from active Mooren’s ulcer after lamellar keratoplasty were cut into paraffin sections and ultrathin sections and observed by light and transmission electron microscopy. The samples taken from patients of a Terrien’s marginal degeneration and a bacterial corneal ulcer were used as controls. Results Chronic inflammation including lymphocytes and plasma cells infiltrating existed in bulbar conjunctiva and sclera of Mooren’s ulcer. Limbal corneal epithelium, Bowman’s membrane, anterior stroma and adjacent superficial sclera melted and the inferior stromal collagen disorganized. The epithelial basement membrane of ulcer progressive edge had been destroyed while the epithelium and stroma kept quiescent. Lymphocytes infiltrated in conjunctiva and corneal epithelium of Terrien’s marginal degeneration with normal epithelial basement membrane, while Bowman’s membrane was destroyed. The epithelial basement membrane of bacterial corneal ulcer was intact. Conclusion Bulbar conjunctiva may act as a local lymph node of Mooren’s ulcer. Epithelial basement membrane of Mooren’s ulcer may have some abnormality as it was invaded first during ulcer progressing and it’s valuable to have a further study.

Objective To investigate the outcomes of arthroscopic reduction and internal fixation with cannulate lag screw for avulsion fracture of tibial intercondylar anterior eminence.Methods From May 2004 to December 2007,30 cases of tibial intercondylar anterior eminence avulsion fracture were treated by arthroscopic reduction and fixation with cannulated lag screw.Among the patients,there were 10 females and 20 males,ranging from 15 to 79 years old with an average age of 32.0.There were 12 fresh fractures and 18 old fractures.According to Meyers-McKeever-Zaricnyl's classification systems,there were 8 cases of type Ⅱ,15 cases of type Ⅲ,and 7 cases of type Ⅳ.Patients were encouraged to do postoperative rehabilitation,such as active joint extension and flexion,exercise of isometric contraction of quadriceps femoris.The treatment outcomes were evaluated by Lysholm and Irrgang knee score system.Results All patients were followed up for 3 months to 60 months(averaging 31.2 months).X rays revealed bony healing 2 months after operation.The joints were stable.Negative Lachaman and drawer and jerk tests were found in all cases,and there was no dysfunction in the knee joints.Lysholm scores were increased from(60.8?1.5)to(95.5?3.5)while Irrgang scores increased from(55.5?3.3)to(90.5?2.5).Conclusion Arthroscopic treatment of avulsion fracture of tibial intercondylar anterior eminence is an easy approach with minimal invasion,and has reliable reduction and fixation with satisfied results.
