Objective Vertebral benign and malignant tumors were intractable in the treatment. Previous treatment methods had their own deficiency. The introduction of percutaneous vertebroplasty brought a breakthrough in the treatment. The initial experience of the treatment of vertebral malignant and benign tumors with percutaneous vertebraplasty was analyzed in this clinical research.Methods and materials The treatment of seven cases of vertebral hemangiomas and 11 cases of vertebral malignant tumors were reported. Unipedicular or bipedicular approaches were used in 17 cases, and in one case of cervical hemangioma, the cervical anterior-lateral approach was adopted. 15-20% of bone cement was mixed and injected into the vertebral lesions and made to distribute and cast in the lesions. Results Good results were got in all the 18 cases. After 0.5-7ml of cement was injected into the lesions. The complete relief was got in 10 cases and sub-complete relief was achieved in 6 cases and medial relief was got in two cases. One to nine months of postoperative follow-ups found no recurrences.Conclusions The treatment of vertebral benign and malignant tumors with percutaneous vertebraplasty was mini-invasive, safe, and effective.

Objective To investigate the application and nursing care of bronchoalveolar lavage (BAL)by fiberoptic bronchoscopy in patients with mechanical ventilation. Methods 64 patients with mechanical ventilation in RICU were randomly divided into the control group and the observation group with 32 patients in each group. The patients in both groups were accepted anti-infection, atomization inhalation and other supportive treatments. The patients in the observation group were treated with BAL, and the patients in the control group accepted routine treatment. The therapeutic effects in the two groups were evaluated and compared. Results There was significant difference in the recovery rate and effective rate, the blood gas analysis compared with the control group was significantly improved, the time of pulmonary infection control window, mechanical ventilation, length of stay were shorter than the control group. The case number to remove ventilator successfully, organs failure and hospital mortality were less than the control group. Conclusions Fiberoptic bronchoscopy with BAL treatment could be safety and efficacy for patients with mechanical ventilation. Nursing intervention plays an important role and a good therapeutic effect for improving achievement ratio of BAL.

Objective To study the effects of D-Ala2-Leu5-enkephalin(DADLE) preconditioning on rabbit donor heart preservation and protective mechanism.Methods 24 rabbits were randomly divided into 4 groups. In group B, after preconditioning with DADLE(1mg?kg -1 ), the donor hearts were then arrested and preserved with Krebs-Henseleit buffer at 4℃ for 4h,and group A without conditioning as controls. Then the donor hearts were transplanted into the abdomen of recipient rabbits. Recovery situation of contraction of the donor heart was compared. The left ventricular tissues were obtained from the donor hearts after 2h of transplantation.The contents of free radicals and ATPase activity were determined and cardiac ultrastructure were observed.Results After 4h cold storage, the heart undergoing DADLE preconditioning in group B showed better recovery of left ventricular development pressure (LVDP).The activity of sodium-potassium ATPase in group B were higher than that in group A. DADLE increased free radical production 2-fold versus group A. Group B showed slighter injury in transmission electron microscopy observation than that in group A.Conclusion Our study demonstrated opioid preconditioning has protective function to rabbit heart injury caused by long term cold storage. The protective mechanism maybe related to increase of free radical content.

Objective To evaluate the effects of long-term high-fat diet on skin wound repair in mice, and to explore its related mechanism. Methods A total of 16 ten-week-old C57BL/6J wild-type mice were randomly and equally divided into two groups to be fed a high-fat diet(HFD group)and a standard diet(SD group)respectively for 8 weeks. Then, an 8-mm full-thickness skin wound was created on the back of each mouse by using a biopsy punch. The degree of wound healing was observed, wound healing rate and epithelialization level were evaluated every day. The weight of mice was measured before feeding, after 8-week feeding and on day 14 after the operation. Peripheral blood samples were obtained from these mice for the determination of total cholesterol(TC)and triglyceride(TG)levels after a 12-hour fast on day 14 after the operation. Then, all the mice were sacrificed, and wound tissues were resected from the dorsal skin of mice for a histological study. The two-sample t test was used to compare the thickness of new epidermis in the wound surface, collagen deposition rate in the wound bed, count of new vessels, levels of cell proliferation and degree of inflammatory cell infiltration between the two groups. Results The average weight of mice was significantly higher in the HFD group than in the SD group after 8-week feeding(27.3 ± 0.7 g vs. 21.2 ± 0.6 g, t = 21.98, P < 0.001)and on day 14 after the operation (28.8 ± 0.7 g vs. 23.1 ± 1.1 g, t = 25.22, P < 0.001). Similarly, there was a significant increase in the levels of TC(1.35 ± 0.32 mmol/L vs. 0.99 ± 0.28 mmol/L, t = 2.24, P < 0.05)and TG(4.21 ± 0.41 mmol/L vs. 2.71 ± 0.31 mmol/L, t = 6.49, P < 0.05)in the HFD group compared with the SD group 14 days after the operation. Compared with the SD group, the HFD group showed shorter healing time (13.5 ± 0.5 days vs. 12.6 ± 1.1 days, t = 1.99, P < 0.05), lower thickness of newborn epidermis on the wound surface (47.8 ± 13.8 μm vs. 95.7 ± 13.7 μm, t = 5.68, P < 0.001), decreased number of CD31-positive vessels(8 ± 1 vs. 13 ± 3, t = 4.1, P < 0.001)and count of ki-67-positive cells(21 ± 4 vs. 49 ± 10, t = 3.33, P < 0.001), but increased count of infiltrating macrophages and mast cells (both P < 0.05). No significant difference was found in collagen deposition rate in the wound bed between the two groups (P > 0.05). Conclusion Long-term high-fat diet can affect wound healing and delay skin wound repair in mice.

Objective To observe the effects of the preconditioning of ulinastatin on GES-1 cell injury induced by oxygen and glucose deprivation (OGD). Methods GES-1 cells were cultured in vitro and divided into three groups: normal control group (group N), oxygen and glucose deprivation group (group O), and ulinastatin preconditioning group (group U). The OGD model of GES-1 cells were established by glucose-free medium and three-gas incubator for 6h. Ulinastatin was added to group U 12h before the deprivation of oxygen and glucose. The cell viability and apoptosis were determined by cck-8 and flow cytometry respectively. Western Blot was used to examine the protein expression of Caspase-3 and Cleaved Caspase-3. The TRPV1 mRNA expression was measured by quantitative real-time PCR. Results As compared with group N, the viability of GES-1 was decreased, the apoptotic rate and the expression of Caspase-3 and Cleaved Caspase-3 were increased, and the TRPV1 mRNA expression decreased greatly in group O (P < 0.05). As compared with group O, the aforementioned changes were significantly inhibited in group U. Conclusions Ulinastatin preconditioning could effectively inhibit GES-1 cell injury induced by OGD, which may be related to the inhibition of apoptosis and the upregulation of TRPV1 mRNA expression.

OBJECTIVETo observe the differences in timely effectiveness of immediate analgesia on acute migraine between electroacupuncture (EA) at shaoyang meridian points and non-meridian points.
METHODSThe randomized controlled trial method was adopted. One hundred and ten cases of acute migraine were randomized into two groups. 55 cases in each one. In the observation group, EA was applied to Fengchi (GB 20), Waiguan (TE 5), etc. In the control group. EA was applied to non-meridian points. Only one treatment was given, and the nee dies were retained for 30 min in the two groups. Separately. at 10 time points, named before acupuncture, in 5 min, 10 min. 20 min and 30 min (at the moment of needle removal), 1 h, 2 h, 4 h, 6 h and 8 h after acupuncture, the pain intensity numerical rating scale (PI-NRS) was adopted to evaluate the pain severity and the adverse reac tion was recorded.
RESULTS(1) The effective rate of imnmediate analgesia was 87. 3% (48/55) in the observation group. significantly higher than 52.7% (29/55) in the control group (P<0.01). (2) NRS of each group was re duced at each time point, from 5 min to 8 h after acupuncture (all P<0.01). (3) NRS score at 30 min after acu puncture in the control group was obviously lower than that in the observation group (P<0.05), but the scores in 2 h, 4 h, 6 h and 8 h after acupuncture in the observation group were lower apparently than those in the control group (all P<0. 01). The differences in the scores in 5 min, 10 min, 20 min and 1 h after acupuncture were not significant (all P>0. 05). (4) For the reducing amplitude of NRS score at the same time point after acupuncture, the results in 20 min, 30 min and 1 h in the control group were higher apparently than those in the observation group (all P<0. 05). But, in 2 h, 4 h, 6 h and 8 h, the results in the observation group were higher apparently than those in the control group (all F<0.05). The differences in 5 min and 10 min after acupuncture were not significant (both P>0. 05). (5) In 24 h after acupuncture, the recurrence rate of migraine was 12. 7% (7/55) in the observation group, which was lower obviously than 34. 5% (19/55) in the control group (P<0. 05). The adverse reaction was not found in the two groups.
CONCLUSIONEA at the shaoyang meridian points achieves the definite immediate analgesia effect on acute migraine and presents the time effectiveness of analgesia.
