Objective To explore the effects of combination of traditional Chinese medicine (TCM)and western medicine on a variety of allergen induced severe perennial seasonal allergic rhinitis patients who were treated invalidly with antihistamines and intranasal flixonase for more than two years.Methods 16 patients with moderate to severe allergic rhinitis who were uncontrolled with antihistamines and intranasal flixonase for one week were treated by combination with TCM of Xin-Yi-Qing-fei San or Gyokubeifu-san mixed formula for two weeks.Nasal symptoms,its effects on the quality of daily life,and telephone follow-up half a year later were evaluated.Mini Rhinoconjunctivitis Quality of Life Questionnaire (Mini-RQLQ) and Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ) were used to evaluate the quality of life.Results After 2 weeks combination-treatment,the nasal symptoms of congestion,rhinorrhea,sneezing,nasal itching,and nasal obstruction were significantly improved compared with combination-before [(52.0± 11.1)％,(69.1±5.3)％,(68.3±12.3)％,(55.5±10.0)％to (10.9±2.4)％,(8.9±3.2)％,(12.5±4.3)％,(13.2±5.3)％,respectively].The before and after treatment of nasal function of nasal minimum cross-sectional area (MCA),nasal cavity volume (V5) and nasal airway resistance (R75 and R150) respectively were (0.58±0.12)cm2,(0.38 ± 0.23) Pa/cm3 · s-1,(0.44 ± 0.32) Pa/cm3 · s-1,(3.50 ± 2.33) cm2 to (0.48 ± 0.23) cm2,(0.31 ±0.33) Pa/cm3 · s-1,(0.31 ±0.37)Pa/cm3 · s-1,(2.24± 1.03) cm2 (P＜0.01).In addition,findings of patients with nasal symptoms by half year follow-up were significantly better than those of before.Conclusion The interventionof TCM can effectively control the perennial and seasonal severe symptoms of patients with AR,and improve the quality of life of patients.

Acute pancreatitis (AP) is an inflammatory disease of the pancreas. Its pathogenesis is not only related to abnormal activation of trypsinogen, but also related to calcium overload, mitochondrial dysfunction, impaired autophagy and endoplasmic reticulum stress. However, the mechanism has not been fully elucidated and needs to be further studied. Currently, there is no effective treatment for AP. It is difficult to prevent the loss of pancreatic function. An in-depth understanding of the pathophysiological mechanisms of AP may help to identify the potential therapeutic targets. Therefore, the purpose of this study is to review recent advances in the mechanism of AP in order to provide more research direction for treatment.

Malignant tumors usually have no obvious clinical symptoms in the early stage. Most patients are already in the advanced stage when they are diagnosed. Some patients have lost the opportunity for operation, resulting in poor prognosis. Therefore, how to find the best therapeutic target for such patients and improve the prognosis of patients has gradually become the focus of scholar′s attention. Recently, Kruppel-like factor (KLF) is a transcriptional regulator that can bind to the target DNA, and its family plays an important role in the occurrence and development of malignant tumors. It has also been confirmed that the KLF family affects the proliferation, differentiation and migration of tumor cells, but the specific mechanism is still not fully elucidate. Consequently, in order to further explored the effect of the KLF family on tumors, this study intends to briefly review the roles and regulatory mechanisms of the KLF family in the cell proliferation, differentiation and migration of malignant tumors, hoping to provide new target for the biological treatment of tumors.

Objective To evaluate the effect of PTH gene polymorphisms on bone mineral density (BMD) at multiple skeletal sites in normal females.Methods PTH gene phenotype was determined by PCR-RFLP of restriction enzyme Bst BⅠin 596 females aged (46.3?13.7) years (20-80 years),and PCR products with or without enzymolytic site were considered as genotype B or genotype b respectively.BMDs of the anteropesterior spine (AP) and supine lateral spine (Lat) of lumbar vertebrae (L_1-L_4),femoral neck (FN),total hip (T-hip), Ward's triangle (Ward),Trochanter (Troch),forearm [radius+ulna ultradistal (RUUD) and total area of radius + ulna (RUT) ] were measured by DEXA (QDR4500A).Results (1) Hardy-Weinberg equilibrium was evident for PTH polymorphisms.The frequencies of genotype were BB 0.784,Bb 0.208,bb 0.008 and frequencies of alleles B,b were 0.888 and 0.112 respectively in 596 normal females.Frequencies of BB,Bb,bb genotypes were 0.781,0.210,and 0.009 respectively in 347 postmenopausal women and their frequencies of alleles B,b were 0.886,0.114.No significant difference was found between post- and premenopausal women in genotype frequen- cy.(2) Comparing their BMDs of AP,Lat,FN,T-hip,Ward,Troch,RUUD and RUT,there was no significant difference between BB and Bb genotypes of pre- and postmenopansal women groups.(3) Logistic regression analysis failed to show any statistical difference between normal and osteoporosis women with regard to PTH phenotype.Conclusion PTH gene polymorphism has little effect on BMD in normal females.

OBJECTIVETo investigate whether hypertonic saline (HS) can induce the synthesis and release of glutamate in cultured hypothalamic astrocytes or C6 cell line.

METHODSAstrocytes were isolated, cultured, purified and identified from the hypothalamus of newborn rat (1 day). The astrocytes were randomly divided into five groups: isotonic (IS) and HS groups, astrocytes were incubated by IS and HS (320 mosM NaCl) medium, respectively, for 1, 3, 5, 10 or 15 min; carbenoxolone (CBX)+IS and CBX+HS groups, astrocytes were pre-treated with CBX (100 mmol/L) for 1 h at 37 degrees C in a 5% CO(2) / 95% atmosphere, then removed to IS and HS medium, respectively, for 1, 3, 5, 10 or 15 min; Ca(2+)+HS group, astrocytes were pre-incubated with Ca Ca(2+) (1,000 micromol/L) for 1 h at 37 degrees C in a 5% CO(2) / 95% atmosphere, followed by a wash with isotonic FBS/DMEM, and then removed to hypertonic saline for 1, 3, 5, 10 or 15 min. The media of five groups were collected to analyze the medium glutamate concentration with high performance liquid chromatography. The astrocytes were fixed and double immunofluorescent stained with anti-glial fibrillary acidic protein (GFAP) and anti-glutamate. The C6 cells were divided into four groups: IS, HS, CBX+IS and CBX+HS groups, and used for quantitative measurement of glutamate in cells by flow cytometry (FCM).

RESULTS(1) Anti-GFAP immunofluorescent signal revealed no significant difference among various time points in each group, or among the five groups. (2) The anti-glutamate immunofluorescent signal was increased in HS group and peaked at 5 min, and decreased and returned to the level of IS group at 15 min (P < 0.01 vs the 5 min of HS group). In CBX+HS group, the glutamate intensity was higher than that in CBX+IS and HS groups. (3) The medium glutamate concentration had no change after treatment with HS for 1 and 3 min, while increased markedly after treatment for 5 min to 15 min (P< 0.01 vs 1 min and 3 min). On the contrary, the medium glutamate concentrations in the CBX+HS or Ca(2+)+HS group were significant lower than that in the HS group (P < 0.01). (4) FCM showed HS and CBX+HS induced glutamate increase in C6 cells.

CONCLUSIONHS induced cultured rat hypothalamic astrocytes or C6 cells to synthesize and release glutamate; CBX could block glutamate release, but could not disrupt glutamate synthesis.

OBJECTIVETo explore the mid-term surgical results of arterial revascularization for femoro-popliteal arterial occlusive disease (lesion type C and D).

METHODSFrom January 2005 to February 2009, 191 arterial bypass had been performed on 170 patients (21 cases bilateral). There were 108 male and 62 female, age ranged from 45 to 85 years old with an average of 67 years old. The operative indication was claudication in 78 cases, rest pain in 62 cases, ischemic ulcer in 19 cases, and distal tissue necrosis in 11 cases. Arterial angiography were performed on all cases. According to TASC II document, type C lesions were seen in 127 limbs, type D lesions were seen in 64 limbs. Autogenous greater saphenous vein bypass in situ were done on 15 limbs, autogenous greater saphenous vein bypass reversed in 20 limbs, revascularization with artificial prosthesis in 128 limbs, composite grafts consisting of a prosthetic conduit with a distal venous segment in 28 limbs.

RESULTSThere were no 30-day mortality. Follow-up periods ranged 6 to 36 months with an average of (24 + or - 6) months. Seventy-three cases were lost during follow-up periods, follow-up rate was 57% (109/191). Primary patency rate was 84.4% (92/109). The patency rate was 88.2% with artificial prosthesis, 70.8% with greater saphenous vein (in situ or reversed). Secondary patency rate was 89.9%.

CONCLUSIONSArterial revascularization with artificial prosthesis is main treatment for diffused superficial femoral artery occlusive disease (TASC II type C and D lesion) with satisfied surgical results.

Carotid endarterectomy(CEA)has been proved to be an effective surgery to treat the cerebral ischemia caused by carotid atherosclerotic stenosis. However,there is still no effective mean for the early diagnosis of the CEA-related severe complications such as stroke and death. Many studies have explored the potential biomarkers for stroke alert,although there is still a long way to go for their actual application in clinical settings. The carotid atherosclerotic stenosis,the perioperative complications of CEA,and the stroke share similar pathogenic mechanisms,and some biomarkers such as S100B,matrix metalloproteinase 9,asymmetric dimethylarginine,and neuron-specific enolase have been studied in the clinical trails of CEA. This article summarizes recent advances in this field.

OBJECTIVETo explore the effective and safety of carotid endarterectomy (CEA) in the treatment of severe stenosis of internal carotid artery.

METHODSThe clinical data of 95 patients with internal carotid artery stenosis and treated by CEA in our hospital from October 1998 to October 2006 were retrospectively analyzed. Transient ischemic attack (TIA) was found in 65 patients and cerebral infarction in 21 patients before operations. Diagnoses were confirmed by selective angiography, and > 70% stenosis of internal carotid artery was found in all patients and > 95% stenosis was found in 50 patients. Stenosis or occlusion of the contralateral carotid artery was also found in 35 patients. Coronary artery stenosis was confirmed in 43 patients with preoperative coronary angiography. CEA and coronary artery bypass grafting (CABG) were simultaneously performed in 18 patients.

RESULTSAfter the operation, the clinical symptoms significantly improved in all patients. One case experienced hypoglossal nerve injury. One patient died of heart attack during follow-up.

CONCLUSIONCEA is an effective and safe treatment for severe stenosis of internal carotid artery.
