Objective:To observe the clinical effects of Jin’s three-needle plusXiang Ju Capsules for allergic rhinitis (AR). Methods:Fifty patients with AR were randomly divided into an acupuncture-medication group and a medication group by the random digital table, 25 cases in each group. The acupuncture-medication group was treated with dorsal three-needle and nasal three-needle in Jin’s three-needle therapy, once every day, plus oral administration of Xiang JuCapsules, 4 pills each time, and three times per day. The medication group was only treated with oral administration ofXiang JuCapsules, 4 pills each time, and three times per day. For both groups, 10-day treatment constituted a course. The therapeutic effects were observed after continuous 2 courses. The symptoms and signs are scored before and after treatment, and the therapeutic effects were assessed based upon the changes of the patient’s symptoms and signs. Results:After treatment, the total effective rate was 96.0% in the acupuncture-medication group and 72.0% in the medication group. The difference in the total effective rate between the two groups was statistically significant (P<0.05). Conclusion:The therapeutic effect was remarkable in treating AR of Jin’s three-needle plusXiang JuCapsules, better than oral administration of Xiang JuCapsules alone.

Objective To discuss the influence of nursing intervention on psychological state and postoperative conffort of diabetic patients with interventional therapy. Methods 49 patients who were to receive interventional therapy were randomized into the experimental group and the control group.The con-trol group received routine nursing while the experimental group was given systemic comfort nursing inter-vention based on routine nursing intervention.The anxiety status and incidence of complications before and after the operation were compared by χ2 and t test. Results The anxiety alleviation in the experimental group was better than that of the control group.The incidence of waist- back pain, dysuria, catheter emic-tion, anaesthesia of lower limbs, fidget in the experimental group also more significantly decreased com-pared with those of the control group. Conclusions Systemic nursing intervention can improve the pay-chological and postoperative comfort for diabetic patients with interventional therapy.

Studies have shown that most of the sequence in the mammalian genome is transcribed into long noncoding RNAs (lncRNAs). Their crucial roles in gene regulation are becoming a hotspot in current biomedical research. LncRNAs can control gene activities through multiple mechanisms such as: 1) direct or indirect regulation of gene expression via cis-/trans-action or function as protein baits in the nucleus; 2) affecting the stability and the translational process of mRNA; 3) functioning as competitors to regulation of microRNA; 4) binding to transcription factors. Recent studies have highlighted the significance of lncRNAs in development and diseases, and their potentials in future clinical application.

Objective To investigate the relation between serum level of fibroblast growth factor (FGF)-23 and left ventricular hypertrophy in non dialysis patients with chronic kidney disease (CKD). Methods One hundred and twenty-four non dialysis patients with CKD were selected. Among them 34 cases were CKD 1-2 stage (CKD 1-2 stage group), 50 cases were CKD 3-4 stage (CKD 3-4 stage group), and 40 cases were CKD 5 stage (CKD 5 stage group). Thirty-two subjects of healthy people were selected as control group. The serum FGF-23, urea nitrogen, creatinine, calcium, phosphorus, intact parathyroid hormone (iPTH) and hemoglobulin levels were measured. The cardiac structural parameters were assessed by Doppler echocardiography, which included left ventricular end-diastolic diameter (LVDd), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT) and left ventricular ejection fraction (LVEF). Left ventricular mass index (LVMI) was calculated by Devereux formula. The patients were diagnosed as left ventricular hypertrophy according to LVMI (male ≥ 125 g/m2, female ≥ 110 g/m2). The relation between FGF-23 and left ventricular hypertrophy was analyzed. Results Among the patients with CKD, left ventricular hypertrophy was in 46 cases (hypertrophy group), non left ventricular hypertrophy was in 78 cases (hypertrophy group), and the incidence of left ventricular hypertrophy in patients with CKD was 37.1% (46/124). The lgFGF- 23, lgiPTH and phosphorus levels in hypertrophy group were significantly higher than those in non hypertrophy group:1.69 ± 0.33 vs. 1.50 ± 0.27, 1.98 ± 0.45 vs. 1.74 ± 0.32 and (1.50 ± 0.59) mmol/L vs. (1.27 ± 0.39) mmol/L, the calcium, albumin, hemoglobulin and LVEF levels were significantly lower than those in non hypertrophy group:(2.06 ± 0.24) mmol/L vs. (2.17 ± 0.20) mmol/L, (35.76 ± 4.18) g/L vs. (39.74 ± 5.73) g/L, (96.65 ± 22.66) g/L vs. (117.15 ± 27.67) g/L and (59.62 ± 12.02)%vs. (67.76 ± 6.69)%, and there were statistical differences (P<0.01 or<0.05). There were no statistical differences in systolic blood pressure and diastolic blood pressure between hypertrophy group and non hypertrophy group (P>0.05). The incidences of left ventricular hypertrophy and LVMI in CKD 1-2 stage group, CKD 3-4 stage group and CKD 5 stage group were significantly higher than those in control group:11.8%(4/34), 36.0%(18/50) and 60.0% (24/40) vs. 3.1% (1/32), (91.18 ± 16.17), (111.25 ± 27.89) and (124.82 ± 24.80) g/m2 vs. (84.41 ± 13.77) g/m2, those indexes in CKD 3-4 stage group, CKD 5 stage group were significantly higher those in CKD 1-2 stage group, and those indexes in CKD 5 stage group were significantly higher than those in CKD 3-4 stage group, and there were statistical differences (P<0.01 or<0.05). The LVMI was positively correlated with lgFGF-23, lgiPTH and history of hypertension in CKD patients (r=0.297, 0.327 and 0.229; P = 0.019, 0.009 and 0.026). The LVMI had negative correlation with calcium, hemoglobulin and LVEF (r=-0.280,-0.432 and-0.432;P=0.028, 0.000 and 0.000). The LVMI had no correlation with phosphorus, systolic blood pressure, diastolic blood pressure, gender and age (P>0.05). Multiple linear regression analysis result showed that LVMI (Y) was negatively correlated with hemoglobulin (X1) and LVEF (X2), and the regression equation was Y = 255.201- 0.424 X1- 1.092 X2. Conclusions The incidence of left ventricular hypertrophy increases gradually with the decline of renal function in non dialysis patients with CKD. The serum level of FGF-23 is related to left ventricular hypertrophy and the degree of heart failure in non dialysis patients with CKD. Anemia and cardiac function state are closely related to left ventricular hypertrophy in non dialysis patients with CKD.

Objective To explore the reasons and clinical characteristics of gastrointestinal bleeding in maintenance hemodialysis patients.Methods Clinical data of 28 hemodialysis patients combined with gastrointestinal bleeding were retrospectively analyzed.The reasons and clinical characteristics of gastrointestinal bleeding were analyzed.Results The incidence rate of gastrointestinal bleeding in hemodialysis patients was 20.9%,hemorrhage of upper digestive tract in 23 cases (82.1%)and hemorrhage of lower digestive tract in 5 cases (17.9%).The reasons of hemorrhage of upper digestive tract were mucosal erosion bleeding of gastric esophagus duodenum in 15 cases (65.2%)and peptic ulcer in 8 cases (34.8%).The positive rate of helicobacter pylori infection was 66.7%(12 /18).In 10 cases (35.7%),gastrointestinal bleeding happened within three months after hemodialysis.Vascular access for hemodialysis were used by central venous catheterization in 13 cases (46.4%)and arteriovenous fistula in 15 cases (53.6%).The prognosis of gastrointestinal bleeding in hemodialysis patients were continuing hemodialysis in 23 cases (82.1%),turned to peritoneal dialysis in 2 cases (7.2%)and death in 3 cases (10.7%).Conclusion The major reason of gastrointestinal bleeding in hemodialysis patients is hemorrhage of upper digestive tract.Mucosal erosion bleeding of gastric esophagus duodenum is major in hemorrhage of upper digestive tract.The positive rate of helicobacter pylori infection is higher.More than 1 /3 gastrointestinal bleeding happens within three months after hemodialysis.The prognosis of the majority of patients is good by internal medicine combined therapies and no heparin hemodialysis.

BACKGROUND:Bone marrow mesenchymal stem cellcontent is less under normal conditions, and easily confounded with other cells. Therefore, to establish a simple feasible in vitro cultured amplification method and to obtain a large number of stable bone marrow mesenchymal stem cells are of important theoretical significance and application value. OBJECTIVE:To establish a simple feasible in vitro culture and amplification method and to obtain numerous stable bone marrow mesenchymal stem cells. METHODS:Bone marrow mesenchymal stem cells were isolated from Sprague-Dawley rats and cultured in vitro using density gradient centrifugation and adherence separation screening. cellmorphological changes were observed under an inverted light microscope. Submicroscopic structure of cells was observed under a transmission electron microscope. Living cellnumber was counted using Trypan blue exclusion method. cellgrowth curve was drawn. cellcycle was analyzed using flow cytometry. The expression of c-kit and CD45 was measured using immunocytochemistry. CD45 expression was analyzed using flow cytometry. RESULTS AND CONCLUSION:(1) celladhesion and pseudopodia could be seen under an inverted light microscope at 24 hours after inoculation;cellcolony formed at 4 days;90%cellconfluence was found at 14 days. After passage, the cells were tended to homogenous and became fibroblast-like cells, which showed whirl-like growing or flamboyancy growing. (2) The size of passage 3 bone marrow mesenchymal stem cells was smal and nucleolus was large, with clear nucleoli under a transmission electron microscope, with the presence of sparse chromatin and low electron density. There was microvil us on the surface of cells, abundant ribosomes could be seen in the cytoplasm with few other cellular organs such as endoplasmic reticulum, mitochondria and Golgi complex. These showed that ultrastructural structure had undifferentiated features. (3) The number of passage 3 bone marrow mesenchymal stem cells was reduced at 1 day after inoculation. The cells began to grow at 2 days, and entered the period of exponential growth at 3 days, entered the flat period at 7 days and the number of cells began to decrease at 9 days. Growth curve exhibited“S”shape. (4) The percentage of S phase cells was 21.1%as detected by flow cytometry after passage 3 bone marrow mesenchymal stem cells were stained by DNA. (5) Immunocytochemistry and flow cytometry had proved that the c-kit positive rate of cells was 53.3%and CD45 positive rate was 1.68%. (6) After osteogenic induction of mesenchymal stem cells for 16 days, cells became oval, and short processes connected each other. The cytoplasm was dark, suggesting that it may be rich in rough endoplasmic reticulum and Golgi complex. They can secrete osteoid. Results verified that obtained bone marrow mesenchymal stem cells stably grew, and actively proliferated.

Vectors used to carry foreign genes play an important role in gene therapy, among which, the adeno-associated virus (AAV) has many advantages, such as nonpathogenicity, low immunogenicity, stable and long-term expression and multiple-tissue-type infection, etc. These advantages have made AAV one of the most potential vectors in gene therapy, and widely used in many clinical researches, for example, Parkinson's disease. This paper introduces the biological characteristics of AAV and the latest research progress of AAV carrying neurotrophic factor, dopamine synthesis related enzymes and glutamic acid decarboxylase gene in the gene therapy of Parkinson's disease.

Forty-five healthy male dogs were wounded with high or middle-velocity steel ball on the lower part of the face.and the findings were as follows:(1)Craniocerebral injuries concomitant with maxillofacial gunshot wounds were charcterized by brain contusion in the entry side of the temporal lobe and extradural hemorrhage in the entry side of the middle cranial fossa,and their highest incidence and severity were found in those cases with mandible fracture due to high-velocity missiles.(2)The larger the amount of the absorbed energy from the bullet,the higher the incidence and severity of the craniocerebral injury.(3)The incidence and severity of the craniocerebral injury were positively correlated to the value of vibrational acceleration measured on the pareital bones,which suggests that vibrational acceleration plays an important role in the precipitation of craniocerebral injury secondary to maxillofacial gunshot wounds.

Objective:To study the fear extent toward root canal therapy (RCT).Methods: A survey with questionnaires was conducted in 103 adult patients who had received RCT.Results:44.7% of the subjects reported a decrease in fearfulness to endodontic procedures as the result of having experienced RCT.Local anesthetic injection,file introducing into or working in root canals and tapping on a sore tooth were ranked as 6th,5th,7th for the fear.Only 50.4% of the patients would choose RCT again for teeth preserving treatment.Conclusion:The fear extent toward RCT depends on the steps of the procedure.Local anesthetic injection,file introducing into or working in root canals and tapping on a sore tooth may be the most factors for anxiety in patients.
