OBJECTIVETo observe the effect of calcitonin gene-related peptide (CGRP) on pulmonary vascular collagen accumulation in hypoxia rats in order to study the effect of CGRP on hypoxic pulmonary vascular structural remodeling and its possible mechanism.

METHODSRats were acclimated for 1 week, and then were randomly divided into three groups: normoxia group, hypoxia group, and hypoxia plus capsaicin group. Pulmonary arterial hypertension was induced by hypoxia in rats. Hypoxia plus capsaicin group, rats were given capsaicin (50 mg/(kg x d), s.c) 4 days before hypoxia to deplete endogenous CGRP. Hypoxia (3% O2) stimulated proliferation of pulmonary arterial smooth muscle cells (PASMCs) and proliferation was measured by BrdU marking. The expression levels of CGRP, phosphorylated ERK1/2 (p-ERK1/ 2), collagen I and collagen III were detected by real-time PCR or Western blot.

RESULTSRight ventricle systolic pressure (RVSP) and mean pulmonary arterial pressure (mPAP) of pulmonary arterial hypertension (PAH) rats induced by hypoxia were higher than those of normoxia rats. By HE and Masson staining, it was demonstrated that hypoxia also significantly induced hypertrophy of pulmonary arteries and increased level of collagen accumulation. Hypoxia dramatically decreased the CGRP level and increased the expression of p-ERK1/2, collagen I, collagen III in pulmonary arteries. All these effects of hypoxia were further aggravated by pre-treatment of rats with capsaicin. CGRP concentration-dependently inhibited hypoxia-induced proliferation of PASMCs, markedly decreased the expression of p-ERK1/2, collagen I and collagen III. All these effects of CGRP were abolished in the presence of CGRP8-37.

CONCLUSIONThese results suggest that CGRP might inhibit hypoxia-induced PAH and pulmonary vascular remodeling, through inhibiting phosphorylation of ERK1/2 and alleviating the collagen accumulation of pulmonary arteries.

A set of primers amplified the VP1 gene of foot-and-mouth disease vims (FMDV) was designed and synthesized. A reverse transcription-polymerase chain reaction (RT-PCR) technique detected the RNA of FMDV was established after selecting the best purification method, reagents and reaction conditions. Samples of fresh milk, lymph node, spinal cord, vesicular skin, milk powder, cotton swab, mouse and meat in daughter-house were detected by RT-PCR, positive rates were41.4% (24/58), 13.33% (2/15), 20% (1/5), 100% (1/1), 100% (1/1), 37.5% (12/32), 100% (2/2) and 10% - 70%, respectively. However, positive rate of cockroach detected by RT-PCR was 0. The results showed that the established FMDV RT-PCR technique provided a more sensitive, specific and reliable method for diagnosis and epizootic study of the foot-and-mouth disease.

Objective To investigate the curative effect of brucellar spondylitis,so as to provide scientific proof for improving the curative level of the disease.Methods Epidemiological information was collected from 113 patients diagnosed as brucellar spondylitis,who were divided into 5 groups according to different drugs and drug combinations of doxycycline,gentamicin,sulfamethoxazole and rifampicin.Then the curative effect was investigated.Twenty-one patients who had greater paoas muscle abscess or Para vertebral abscess,intraspinal abscess of spinal canal,necrotic intervertebral disk and major osteolasia received the minimal invasive surgery and the focus removal surgery.Results The occurrence of the disease in female was much higher than that in male.Grazing and breeding beasts was the principal route of infection.Lumbars was mostly involved.they usually was infected in the adjacent 2 piece.L4 was the most common and seriuous one.The curative effect of doxycycline group was better than that without doxycycline(72.60% vs 35.00%,X2=15.14,P＜0.05).Doxycyeline+gentamicin+sulfamethoxazole was reeommended as the first choice.However,the curative effect did not increase despi~course of the treatment prolonged.The heMing rate and effective rate after 1 course was 52.21%(59/113)and 92.04%(104/113).that after 2 courses 58.41%(66/113)and 95.58%(108/113),that after 3 courses 59.29%(67/113)and 95.58%(108/113).The healing rate in different course did not present differences(P＞0.05).21 patients undergoing surgery were followed-up,12 patients were after 2 years and 9 patients were between 1-2 years.The healing rate was 95.24%(20/21),1 case was healed basically,the effective rate was 100%.None reoccurred.Conclusions There are characterized features in clinical epidemiology of the brucell spondylitis.Long term,adequate in dosage,combination and multi-approach use of antibiotics is the most reliable way to treat and prevent it from recurring.But fof the patients soitable for surgery.the minimal invasive surgery or the focus removal could shorten the course of therapy,decrease the complications and increase the cure rate.

OBJECTIVETo observe the clinical efficacy difference between segmentation scraping and conventional acupuncture for cervical spondylosis (CS) so as to provide effective treatment method.

METHODSEighty-five cases of cervical type of CS were randomly divided into a scraping group (44 cases) and an acupuncture group (41 cases). The segmentation scraping therapy was used in the scraping group. The scraping group was treated with focusing on scraping the head and joint part of neck and occiput in the upper cervical spine injury, and focusing on scraping the lower section of cervical and shoulder in the lower cervical spine injury, once every seven days, totally for 3 times. In the acupuncture group, Fengchi (GB 20),Wangu (TE 5), Tianzhu (BL 10),Neck-Jiaji (EX-B 2), etc. were selected,once daily,for 15 days. The visual analogue scale (VAS) was used to evaluate the immediate analgesic effect after the first treatment and the clinical efficacy was observed after the end of treatment.

RESULTSAfter the first treatment, the score of VAS was decreased significantly in the scaping group (P < 0.01), but there was no significant difference in the acupuncture group compared with those before treatment (P > 0.05); the score of VAS in the scaping group after the first treatment was lower than that in the acupuncture group (3.66 +/- 0.74 vs 5.43 +/- 0.35, P < 0.01). Compared with before treatment, the scores of VAS were decreased significantly after treatment in two groups (both P < 0.01), but without significant difference between two groups (P > 0.05); the effective rate was 95.5% (42/44) in the scaping group and 87.8% (36/41) in the acupuncture group, the curative effects were similar (P > 0.05).

CONCLUSIONBoth of scraping and acupuncture therapies have good analgesic effect for cervical spondylosis, and overall effects are similar, but the immediate analgesic effect of scraping thrapy is better than that of conventional acupuncture.

Objective To investigate the correlation between family cohesion and adaptability and quality of life in patients with enterostomy. Methods Using Chinese version of Family Adaptability and Cohesion Scale (FACESⅡ-CV) and Chinese version of Stoma-Quality of Life (STOMA-QOL-C) to investigate the status of family cohesion and adaptability, family type and their impact on quality of life of 110 patients with enterostomy. Results Scores of family cohesion and adaptability averaged 59.15 ± 11.94, 47.32 ± 9.40,were significantly lower than 63.90 ± 8.00 and 50.90 ± 6.20 in the norm,and the difference was statistically significant (t=-4.171,-3.990, P<0.01).The family cohesion was positively correlated with the score of quality of life, social interaction and psychological burden(r=0.274, 0.284, 0.263, P<0.05), and the family adaptability was positively correlated with the score of quality of life,social interaction and psychological burden(r=0.316, 0.338, 0.228, P<0.05 or 0.01). The balance type family was 30 cases;scores of quality of life averaged 45.10±7.26, the intermediate type family was 50 cases;scores of quality of life averaged 43.48±9.98, the extreme type family was 28 cases;scores of quality of life averaged 43.37 ± 16.68, and difference between the three was no statistically significant(F=0.442, P=0.665). Conclusions In the nursing process of patients with enterostomy, health care workers should pay attention to improve family cohesion and adaptability, as to achieve the purpose of improving the quality of life of the patients.

Objective To investigate the relationship between coagulation factor ⅩⅢ deficiency and delayed intracranial hematoma after craniotomy. Methods The clinical data of 2 cases with delayed intracranial hematoma induced by coagulation factor ⅩⅢ after craniotomy were analyzed and compared with the data of 58 cases with delayed intracranial hematoma induced by other causes during the same period, so as to find out the clinical characteristics of the disease induced by coagulation factor ⅩⅢ. Results The delayed intracranial hematoma induced by the deficiency in coagulation factor ⅩⅢ was commonly located in the operative regions after surgery, and the process was insidiousand fast. Conclusion When the delayed intracranial hematoma is confirmed after craniotomy, the deficiency in coagulation factor ⅩⅢ should be taken into consideration. The prognosis will be satisfying if the diagnosis and treatment are in time.

OBJECTIVETo investigate changes of brain mast cells after transient global ischemia in rats.

METHODSTransient global ischemia damage was induced by four-vessel occlusion. After 1 h to 14 days of ischemia, rats were perfused intracardially by 4% paraformaldehyde. The brains were dissected to serial sections using freeze microtome, and then stained with toluidine blue. Brain mast cell was observed under microscope.

RESULTMost brain mast cells were located in thalamus. The number of mast cells in thalamus markedly decreased during reperfusion after transient global ischemia. However, the degranulation rate of thalamus mast cells showed reverse change after ischemia.

CONCLUSIONBrain mast cells markedly degranulate after transient global ischemia, which may be involved in the pathological process after ischemia.
