Objective To study the influence of bFGF gene transfected bone marrow-derived mesenchymal stem cells (BMSCs) on the inflammatory cytokines of COPD rat. Methods The BMSCs were separated from SD rat and cultured and then bFGF gene was imported to BMSCs by liposome transfection method. The samples were prepared into six groups: normal control group, COPD group (A), BMSCs group (B), pcDNA3.1-BMSCs group (C), bFGF-pcDNA3.1-BMSCs group (D), and bFGF group (E). The expressions of TNF-α and IL-1β by QRT-PCR were detected. Results Compared with COPD group, TNF-α and IL-1β genes from groups B to D dropped significantly (P < 0.05). The changes of TNF-α and IL-1β genes among groups B to D showed no significant difference (P > 0.05). Conclusion BFGF transfected BMSCs, sample BMSCs and pcDNA3.1 transfected BMSCs can inhibit the expression of inflammatory cytokines of TNF-α and IL-1β, but there is no obvious advantage in comparison to bFGF transfected BMSCs and sample BMSCs in respect of inhibiting the expression of inflammatory cytokines of TNF-α and IL-1β.

Objective To compare the clinical outcome of unipedicular versus bipedicular vertebroplasty treating for osteoporotic vertebral compression fracture.Methods Sixty-four patients(68 vertebra)were divided into two groups by treated methods:unipedicular kyphoplasty group(33 cases)and bipedicular vertebroplasty group(31 cases).The Cobb angle and vasual analogue pain scale(VAS)were measured preoperatively and postoperatively.The operation time was recorded.Compared the Cobb angle,VAS and the operation time between two groups.Results Of unipedicular kyphoplasty group preoperative,24 hours and 3 months after operation,VAS were(8.42 ± 1.33),(2.21 ± 1.67),(2.09 ± 1.58)scores,the Cobb angle were(31.24 ±9.12)°,(14.21 ±9.21)°,(14.43 ±9.36)° ;while those of bipedicular vertebroplasty group were(8.36 ± 1.52),(2.13 ± 1.80),(2.00 ± 1.71)scores and(30.84 ±8.77)°,(13.94 ± 8.87)°,(14.07 ± 9.87)°.VAS and the Cobb angle of both groups at 24 hours and 3 months after operation were lower than those preoperative(P＜ 0.01).VAS and the Cobb angle of both groups were similar at the same time preoperatively and postoperatively(P ＞ 0.05).The operation time of unipedicular kyphoplasty group and bipedicular vertebroplasty was(45.00 ± 8.76),(72.00 ± 9.32)min,respectively,there was statistically significant difference between two groups(P ＜ 0.01).Conclusions Compared with the bipedicular vertebroplasty,the advantages of unipedicular kyphoplasty are as follows:less trauma,less operation time and less X-rays rediation accepted of the patient and the operator.And it has the similar clinical outcome with the bipedicular vertebroplasty.

Objective To investigate the effect of intrathecal gastrodin on skin cancer pain in mice.Methods Thirty-two female Balb/c mice,aged 8 weeks,weighing 20-25 g,were randomly divided into 4 groups (n=8 each) using a random number table:sham operation group (group S),skin cancer pain group (group SCP),gastrodin group (group G),and artificial cerebrospinal fluid (ACSF) control group (group ASCF).Skin cancer pain was produced by injecting phosphate buffer solution 20 μl containing about 2 ×105 4T1 breast cancer cells into the plantar surface of the left hindpaw.At 14th day after inoculation of cancer cells,ASCF 5 μl was injected intrathecally in S and ACSF groups,and gastrodin 150 μg/kg (5 μl) was injected intrathecally in group G.Before inoculation,at 30 min before intrathecal injection,and at 15,30,60,90,120 and 150 min after intrathecal injection,the thermal paw withdrawal latency (TWL) was measured.The expression of acid-sensing ion channel (ASIC)-3 mRNA in the spinal dorsal horn was detected using the real-time reverse transcriptase polymerase chain reaction after the last measurement of the pain threshold.Results Compared with group S,the TWL was significantly decreased at each time point before and after intrathecal injection in SCP,ACSF and G groups,and the expression of ASIC-3 mRNA in the spinal dorsal horn was significantly down-regulated in group G (P＜0.05).Compared with group SCP,the TWL was significantly increased at each time point after intrathecal injection,and the expression of ASIC-3 mRNA in the spinal dorsal horn was significantly down-regulated in group G (P＜0.05),and no significant change was found in the parameters mentioned above in group ACSF (P＞0.05).Conclusion Intrathecal gastrodin can reduce skin cancer pain and down-regulate ASIC-3 expression in the spinal dorsal horn which is helpful in maintaining the analgesic effect in mice.

Prostate cancer is a common malignancy that affects men's health in the Western countries. Single nucleotide polymorphisms (SNPs), as the third generation of genetic markers, can influence the development, progression, and prognosis of prostate cancer. The same SNP may be related differently with prostate cancer among different races. This paper describes the relationship between SNPs and prostate cancer according to their related genes. SNPs can predict the risk of prostate cancer as well as the possible adverse reactions in its treatment, but at present they do have some limitations.

BACKGROUND: There are obvious neuropsychological changes after stroke besides the damage of cognitive function, and the symptoms of depression and anxiety which are also very conspicuous.OBJECTIVE: To investigate the related characteristics of neuropsychological changes after stroke by means of neuropsychological methods.DESIGN: A case-control study.SETTING: Department of Psychology, the Third Hospital of Daqing; Department of Neurology, the Second Affiliated Hospital of Harbin Medical University.PARTICIPANTS: Sixty stroke inpatients (33 males and 27 female)aged from 42 to 75 years old with an average of (59.3±8.8) years old were selected from the Department of Neurology, the Second Affiliated Hospital of Harbin Medical University between October 2001 and June 2002. Totally 49 cases had cerebral infarction and 11 cases had cerebral hemorrhage; 31 cases had single focus and 29 cases had multiple focuses (including 2 focuses or more); 20 cases had lesion in left hemisphere,21 cases had lesion in right hemisphere and 19 cases had bilateral lesions. The lesion was at temporal lobe in 6 cases, at occipital lobe in 2 cases, at frontoparietal temporal lobe in 15 cases, at internal capsule in 4 cases, at basal nuclei in 19 cases, at lateral ventricle in 4 cases, at thalam us in 4 cases, at cerebellum in 1 case and at multiple sites in 5 cases. The focal size was ＜ 15 mm in 33 cases and ≥ 15 mm in 27 cases. Sixty residents (33 males and 27 females) aged 42to 75 years with an average of (58.7±7.9) years old were selected simultaneously from the communities and suburbs of Harbin city as the controls and they all had no cerebral and organic lesion, mental disorder, severe somatic diseases and family history of mental disease.INTERVENTIONS: The poststroke mental status of the patients at stable recovery period was assessed with symptom checklist-90 (SCL-90, consisted of 90 items and 9 symptoms, scored by 5 grades of 0 to 4, including 0 as never, 1 as mild, 2 as moderate, 3 as a little severe and 4 as severe;Hamilton depression scale (HAMD, consisted of 24 items, including 11 somatic symptoms scored by 0 to 2 grades and 13 mental symptoms scored by 0 to 4 grades; the total score ＞ 24 points was taken as severe depression, 17 to 24 as moderate depression, 7 to 16 as mild depression, ＜ 7 as no depression), self-rating depressive scale (SDS, consists of 20 items, evaluated according to the occurrence frequency of the symptom, and classified into 4 grades; the score was 1, 2, 3 and 4 points for the forward scored questions, but 4, 3, 2 and 1 point for the backward scored questions; the highest total score was 80 points; the depressive severity=accumulative scores of each item/80×100, the depressive index ranged 25 to 100, the index ＜ 0.5 was taken as no depression, 0.5 to 0.59 as mild depression,0.6 to 0.69 as moderate depression, ＞ 0.7 as severe depression) and selfrating anxiety scale (SAS, consisted of 20 items, scored by 4 grades, mainly evaluated according to the occurrencefrequency of the symptoms. The forward scores were 1, 2, 3 and 4 points, and the backward scores were 4,3, 2 and 1 point; the total score multiplied by 1.25, and then the integer was taken as the standard score, the lower the better, and the delimitative value was 50. The total score of anxiety ＜ 50 points was taken as normal,50 to 60 as mild anxiety, 61 to 70 as moderate anxiety, ＞ 70 as severe anxiety). According to the different characters of disease, the patients with moderate depression and above were given suitable psychotherapy and psychiatric drugs for 4 weeks as a course.of the 4 scales between stroke patients with different lesion natures, foin the patients accompanied by depression. RESULTS: All the 60 stroke patients and 60 eases in the control group were involved in the analysis and SAS between the stroke group and control group: All the total scores were higher in the stroke group than in the control group [(131.45 ±18.89), (94.25 ±9.08) points; (18.73 ±6.54), (8.60 ±2.39)points; (56.49±11.85), (41.63±9.91) points: (40.08±6.55), (28.72±1.84)the 4 scales between stroke patients with different lesion natures, focal sites and focal sizes: In the stroke group, the total scores were higher in the patients with lesion in left hemisphere, cortical lesion, multiple focuses and large focal size (≥ 15 mm) than in those with lesion in right hemisphere, subcortical lesion, single focus and small focal size (＜ 15 mm)(t=1.92 to 4.31, P ＜ 0.05), but the scores were almost the same between the patients with cerebral infarction and those with cerebral hemorrhage accompanied by depression before and after treatment: 21 patients had moderate depressive symptoms and above, and their total scores of SCL90, HAMD, SDS and SAS were obviously higher than those in the control group (t=7.45 to 13.75, 9.83 to 21.20, P ＜ 0.01).CONCLUSION: The poststroke neuropsychological changes are more obvious, and the changes are associated with the lesion location, focal size and focal site, but have no close correlation with the lesion nature.After psychological interventions, the depressive emotion is markedly ameliorated in the patients with obvious depressive symptoms and it is then indicated that poststroke patients should be given psychological interventions.

Objective To explore the methodology of choosing the volume and shape of the mammary implant.Methods The changes of the volume and shape were analyzed in 502 cases of breast augmentation,to find out how to select the volume and shape of the mammary implant.Results The thoracic width H was the most important factor of choosing width of the implant; the SN was the important factor of choosing the height of the anatomic implant; After setting the diameter and height of the implant,a bigger breast could be achieved by increasing the projection of implants.For those very thin females with flat chest, anatomic implants were the better choice. Conclusions Thoracic width,breast volume and other data are the most important factors in choosing the mammary implant.Round and anatomic mammary implants have their specific indications.
