Objective To compare and investigate the efficacy of small bone window via lateral fissure and cranial awl hole puncture aspiration via temporal lobe in treatment of hypertensive intracerebral hemorrhage (HIH) in basal ganglia. Methods Eighty-two patients with HIH in basal ganglia were divided into group A (34 cases) and group B (48 cases) by random digits table method. The patients in group A underwent small bone window via lateral fissure, and the patients in group B underwent cranial awl hole puncture aspiration via temporal lobe. The hematoma clearance rate, short-term effects, Barthel index, Scandinavian stroke scale (SSS) score and complications were compared between 2 groups. Results The Hematoma clearance rate and excellent rate in group A were significantly higher than those in group B:(91.12 ± 6.55)%vs. (55.83 ± 4.32)%and 52.94%(18/34) vs. 33.33%(16/48), the incidence of complications was significantly lower than that in group B:5.88%(2/34) vs. 22.92%(11/48), and there were statistical differences (P<0.05). The SSS score 14 d after operation and Barthel index 60 d after operation in group A were better than those in group B:(29.72 ± 6.39) scores vs. (26.43 ± 6.11) scores and (83.91 ± 17.82) scores vs. (72.34 ± 15.62) scores, there were statistical differences (P<0.05 or<0.01). Conclusions The efficacy of small bone window via lateral fissure in treatment of HIH in basal ganglia is better than cranial awl hole puncture aspiration via temporal lobe, however, surgical trauma is relatively large, and operation should be a reasonable choice according to the specific circumstances of patients.

Objective To report the clinical observation and nursing points for recurrent or refractory and aggressive non-Hodgkin's lymphoma treated with MINE regimen. Methods Patients (46 cases) with recurrent or refractory and aggressive non-Hodgkin's lymphoma were given mental nursing,preparation and evaluation of the condition of patients before chemotherapy. Complications especially extravasation of infusion fluid should be prevented during chemotherapy and myelosuppression and long-term complications should be prevented after treatment. Results No patient died after treatment but several complications such as infection(14 cases), nausea and vomiting (grade Ⅰ～Ⅱ, 22 cases, grade Ⅲ,2 cases), alopecia (grade Ⅰ～Ⅱ, 27 cases), mucositis (grade Ⅰ～Ⅱ, 4 cases), liver function lesion (grade Ⅱ, 1 case) were found and improved after proper treatment. No nephrotoxicity and hemorrhagic cystitis were found. Conclusions Selective mental nursing,proper chemotherapy preparation,evaluation of patients' condidtion and positively prevention of chemotherapy-related complications could increase the chemotherapy effect of patients with recurrent or refractory and aggressive non-Hodgkin's lymphoma.

Objective To observe the function of recombinant human tissue factor pathway inhibitor1(rTFPI-1)in acute myocardial infarction in rabbit. Method Forty New Zealand White rabbits were subjected to coronary artery occlusion for 120 min and followed by reperfusion for 60 min,then they were ranlow dose rTFPI-1 group(n=10/group).The extent of ischemic area and the extent of myocardial infarction area were measured by Evan's blue stain and TTC stain,respectively.The degrees of infarction severity and ischemic severity were expressed as the ratios of the total left ventrieular wall area.The degrees of infarction severity and ischemic severity in different groups were compared by using one-way ANOVA and then followed by LSD procedure.Results The degree of infarction severity in the larger dose rTFPI-1 group was significantly lessened than that in low dose RTFPI-1 group and control group(P<0.001),and than that in modcrate dose rTFPI-1 group as well(P<0.05).The degree of infarction severity in the moderate dose rTFPI1 group was significantly lessened than that in low dose rTFPI-1 group and control group(P<0.001).There was no significant difference in degree of infarction severity between low dose rTFPI-1 group and control group(P>0.05).Conclusions Human rTFPI-1 might decrease myocardial infarction severity and save the survival myocardial tissue.

Hedgehog signaling pathway is a conserved and important signaling pathway involved in proliferation and differentiation of many types of cells. Latest studies have found that Hedgehog signaling pathway may induce MSCs osteoblast differentiation by increasing the expression of the Runx2 and Osx and inhibit MSCs differentiate to adipocyte. Hedgehog signaling pathway may also promote osteoblast proliferation by regulating cyclin. This review summarizes the mechanism that Hedgehog signaling pathway regulates osteoblast differentiation and proliferation,and concludes that Hedgehog signaling pathway can regulate bone metabolism. It might provide new ideas for the treatment of osteoporosis.

OBJECTIVETo observe the clinical effect of chronic fatigue syndrome (CFS) treated with moxibustion at Gaohuang (BL 43).

METHODSWith stratified block randomization, 72 patients accorded with inclusive criteria were divided into a moxibustion at Gaohuang (BL 43) group (moxibustion group) and an acupuncture group, 36 cases in each one. In the moxibustion group, Gaohuang (BL 43) was treated with big moxa cones as the main acupoint, 10 cones a time; Qihai (CV 6) and Zusanli (ST 36) were added with big moxa cones, 7 cones a time. In the acupuncture group, acupoints were the same as those in the moxibustion group, and twirling reinforcing method was used after qi arriving, 60 times one minute and 360° with range. In the two groups, 10-day treatment was made into one course and there were two days between courses. The treatment was given once a day for 3 courses. Changes of fatigue assessment index (FAI) before and after treatment and clinical effects were observed.

RESULTSThe total effective rate was 88.9% (32/36) in the moxibustion group, which was better than 72.2% (26/36) in the acupuncture group apparently (P < 0.05). After treatment in the two groups, FAI scores were obviously declined compared with those before treatment (both P < 0.01) and FAI score in the moxibustion group was apparently lower than that in the acupuncture group (P < 0.05).

CONCLUSIONMoxibustion at Gaohuang (BL 43) can improve the FAI score of patients with CFS and the clinical efficacy is definite.

Objective: The BCR-ABL fusion gene induced by reciprocal translocation of t (9; 22) (q34; q11) plays an important role in the pathogenesis of chronic myeloid leukemia (CML). Using recombinant ade-noviruses carrying the N-terminal oligomerizaton domain (OD) of the BCR/ABL and chimeric ubiquitin ligase β-TrCP, this study was to investigate the effect of the targeted degradation of oncoprotein BCR-ABL by Ubiqui- tin-Proteasome System on the proliferation of leukemia call line K562. Methods: The recombinant adenovirus-es carrying wild-type β-TrCP gene (Ad5β-TrCP-OD-HA), mutational β-TrCP gene (Ad5 A F-TrCP-OD-HA)and green fluorescent protein gene (Ad5GFP)were amplified in 293 calls and co-infected into K562 cells respec- tively. The rates of infection were analyzed by flow cytometry (FCM). Recombinant protein and BCR-ABL ex-pression was detected by Western blot. Cell proliferation was determined by cell counting and methylcellu- cose clonal cell culture. Cell cycle was observed through FCM. Untreated K562 cells were used as blank con-trols. Result: The leukemia K562 cell lines with exogenous recombinant β-TrCP-OD-HA and F-TrCP-OD-HA gene were established. The infection rates in the three groups were over 66.4% and recombinant protein sus-tained to be expressed. Ad5β-TrCP-OD-HA down-regulated the expression of BCR-ABL and inhibited prolifer-ation of K562 cells. FCM showed that the percentage of cells at S phase was decreased to 10.88%±2.42%, while that of cells at G_0/G_1 was increased to 85.6%±5.61%, with a significant difference (P<0.05). No changes were found in the cell cycle in groups of Ad5 △ F-TrCP-OD-HA and Ad5GFP. Conclusion: There is sustained ex-pression of recombinant β-TrCP-OD-HA protein in K562 cells infected by recombinant adenovirus.β-TrCP-OD-HA could inhibit the proliferation and clonogenicity of K562 cells through targeted degradation of oncoprotein BCR-ABL and arresting the progression of call cycle.

Objective To evaluate the dosimetric effects of air cavity on primary tumor and organs at risk (OARs) during intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma patients.Methods Nine patients with nasopharyngeal carcinoma had CT simulation before treatment and on the 25 fraction of radiotherapy.Radiotherapy plan1 was first created by delineating the target volumes and OARs on the first CT image, which was then copied and merged with the second CT image.Air cavity that was formed following tumor volume regression was delineated on the first CT image, and the density of air cavity was set to zero.A new gross target volume (GTV) was formed by subtracting the air cavity from the original GTV, and the new CT image was named CTAir.Plan2 was then created by calculating the dose distribution on CTAir using the same portals and parameters as Plan1.Assuming that Plan1 and Plan2 were both used throughout the course of radiotherapy, the dosimetric parameters of nasopharyngeal tumor and OARs in the absence and presence of air cavity were then compared using the paired t-test.Results Dmean, D95, D90, D10, and D5 of tumor were significantly higher in plan2 than in plan1(P=0.000, 0.001, 0.001, 0.001, and 0.005, respectively), with a<0.5 Gy increase in dose.A dose build-up effect was observed within the tumor region posterior to the air cavity, where the highest dose was 1.4 cm posterior to the air cavity, resulting in a dose difference of 0.36 Gy.In addition, D2cc and D1cc of the brain stem were significantly higher in plan2 than in plan1(P=0.036 and 0.044, respectively).Dmax of the optical chiasm, left optical nerve, and right optical nerve were also increased in the presence of air cavity (P=0.438, 0.434, and 0.477, respectively), but the change in dose was<0.12 Gy.Conclusions Air cavity induces a small but negligible increase in the tumor and OARs dose in patients with nasopharyngeal carcinoma during IMRT.However, closer monitoring should be conducted for patients with OARs that is close to or has surpassed tolerance prior to radiotherapy.

Objective To study the changes of resting-state brain activity in knee osteoarthritis(KOA)patients with chronic pain.Methods The data of 21 KOA patients (KOA group) and 21 healthy controls (HC group) who underwent standard resting-state fMRI scan were analyzed with regional homogeneity (ReHo) method to observe the changes in the patients in contrast to the controls.Results Compared to HC group,patients of the KOA group showed ReHo changes in bilateral frontal lobe,bilateral parietal lobe,bilateral temporal lobe,bilateral cerebellum,limbic system and default-mode network.Conclusion Patients with chronic pain demonstrate abnormal neuron activities in the brain regions, and control loops not only related with pain but also related with emotive function disorder and cognitive impairment.
