OBJECTIVETo compare the clinical efficacy difference between electroacupuncture (EA) at qijie area combined with spine balance-regulating massage and medication for posterior circulation ischemia (PCI).

METHODSOne hundred cases of PCI were randomly divided into a treatment group (50 cases) and a medication group (50 cases). The treatment group was treated with EA at Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Shenshu (BL 23), Danzhong (CV 17), etc. in qijie area combined with spine muscle-relieving massage and comprehensive chiropractic. The medication group was treated with oral administration of nimodipine (30 mg per time, three treatments per day) and vinpocetine injection with 500 mL of glucose injection or intravenous drip of 500 mL 0.9% sodium chloride injection, once a day. Ten treatments were taken as one course in both groups, and two courses were given. The symptom score, mean resistance index (RI) of vertebral artery (VA) and basilar artery (BA), mean velocity of blood flow (Vm) and comprehensive clinical efficacy were compared before and after treatment in two groups.

RESULTSThe cured and markedly effective rate was 79.6% (39/49) in the treatment group, which was superior to 54.7% (23/42) in the medication group (P<0.05). The symptom score was both significantly improved after treatment in two groups (both P<0.05), which was more obvious in the treatment group (P<0.05). The RI of VA and BA, Vm of VA and BA were significantly improved after treatment in two groups (all P<0.05), which were more obvious in the treatment group (all P<0.05).

CONCLUSIONThe electroacupuncture combined with spine balance-regulating massage has superior effect on improving mean velocity of blood flow and resistance index of vertebral artery and basilar artery as well as symptom score to medication, and is believed to be a safe and effective treatment for posterior circulation ischemia.

Objective To investigate the diagnostic value of determination of the genotypes in codon 12 and 13 of K-ras oncogene in blood samples of patients with pancreatic carcinoma(PC).Methods Blood samples were obtained from 54 patients with pathologically confirmed PC,and 33 healthy controls.The DNAs were obtained in these samples.and then genotype of K-ras mutation was detected by using the PNA-clamping real-time quantitative PCR.Then the correlation between the K-ras genotypes of blood DNA and the clinical characteristics was analyzed.Results K-ras mutations were found in 74.1%(40/54)of patients with PC.There was no such mutation in control samples.The mutations of K-ras was associated with age,lymph node and vessel invasion.poorly differentiated tumor,CA19-9,while it was not associated with sex,tumor location,size of tumor,clinical staging and pathological type.Conclusions The one-step method was highly sensitive for detecting K-ras mutation in blood samples.Detection of circular blood cells harboring K-ras mutation suggested the tumor was highly invasive with poor prognosis.

Objective To evaluate the clinical efficacy of ultrasonic ablation in patients with chronic deep vein thrombosis of lower extremities. Methods Fifty-six patients with chronic deep vein thrombosis resulting in total occlusion of iliac-femoral veins accepted intra-venous ultrasonic ablation. The time for ultrasonic ablation was 12-24 minutes with the mean being 18 minutes. After the procedure, anti-coagulation was performed through the retaining catheters and venous propeller was utilized for promoting blood reflow. Results Ultrasonic ablation easily created a channel within the occlusive iliac-femoral veins and achieved successful recanalization in 49 of 56 patients (87.5%). Five patients (8.9%) were partially re-canalized and 2 (3.6%) had no recanalization. Thirty-eight of the 49 re-canalized patients were followed up, including 22 with no stent placement showed 9 (40.9%) re-occlusion and 16 received stent placement, and 2 had (12.5%) re-occlusion. Conclusions Intravascular ultrasonic ablation is an effective therapeutic modality to recanalize chronic thrombosed occlusion of iliac-femoral veins and can lay down a foundation for further balloon-expansion or stent-placement with long term patency.

Objective To compare the efficacy between three-dimensional radiotherapy (3DRT) combined with chemotherapy and radiotherapy alone for patients with esophageal squamous cell carcinoma.Methods A retrospective analysis was performed for 1257 patients with esophageal squamous cell carcinoma who were admitted to our hospital from July 2003 to June 2012 and met the inclusion criteria;362 patients were treated with 3DRT combined with chemotherapy (chemoradiotherapy group) and 895 patients were treated with radiotherapy alone (radiotherapy group).The short-term outcome, overall survival (OS) rate, and causes of death were analyzed.The Kaplan-Meier method was used to calculate survival rates, and the log-rank test was used for survival difference analysis and univariate prognostic analysis.Results The response rate was 99.1%(346/349) in the chemoradiotherapy group and 99.0%(813/821) in the radiotherapy group (P=0.397).The 1-, 3-, and 5-year OS rates were 74.0%,42.0%,and 32.9% in the chemoradiotherapy group and 65.9%,33.0%,and 23.3% in the radiotherapy group (P=0.000), and were 75.6%,43.5%,and 33.2% in the concurrent chemoradiotherapy group and 65.9%,33.0%,and 23.3% in the radiotherapy group (P=0.000).There were no significant differences in 1-, 3-, and 5-year OS rates between the concurrent chemoradiotherapy group and the sequential chemoradiotherapy group (P=0.583).The sequential chemoradiotherapy group had an insignificant increase in 1-, 3-, and 5-year OS rates compared with the radiotherapy group (P=0.065).Tumor recurrence and local control failure were the main causes of death, followed by distant metastasis.The chemoradiotherapy group had a significantly lower proportion of patients who died of local control failure than the radiotherapy group (7.4% vs.14.7%, P=0.003).Conclusions For patients with esophageal squamous cell carcinoma, chemoradiotherapy leads to significantly improved overall survival compared with radiotherapy alone;compared with radiotherapy alone, sequential chemoradiotherapy results in an increasing trend in OS rates, while concurrent chemoradiotherapy results in significantly increased OS rates.Chemoradiotherapy can reduce the deaths due to local control failure compared with radiotherapy alone.

OBJECTIVETo compare the difference in the clinical efficacy on primary trigeminal neuralgia (PTN) between the comprehensive therapy of electroacupuncture (EA) at qi streets acupoints combined with spinal regulation method and medication with carbamazepine (CBZ).

METHODSSixty patients were randomized into a comprehensive therapy group (30 cases) and a medication group (30 cases). In the comprehensive therapy group, the acupoints at qi streets on the head such as Taiyang (EX-HN 5) and Sishencong (EX-HN 1) and those at qi streets on the chest and abdomen such as Shenshu (BL 23), Zhongwan (CV 12) and Guanyuan (CV 4), etc. were selected. After arrival of qi, EA was attached on 2 to 4 groups of acupoints. After acupuncture, the spinal regulation method was applied. This comprehensive therapy was given once a day. In the medication group, CBZ was used for oral administration, 100 mg at the first time, twice a day, and 400 to 600 mg each day as the maintenance dose. Separately, before and after treatment, in 2 and 6 months in follow-up, pain rating index (PRI), life satisfaction index B (LSI-B) and hamilton depression scale (HAMD) were adopted to evaluate comprehensively the clinical efficacy in the two groups and compare the adverse reaction during the treatment between the two groups.

RESULTSAfter treatment, the curative and markedly effective rate in the comprehensive therapy group was 76.7% (23/30), which was better than 63.3% (19/30) in the medication group (P < 0.01). The difference in PRI was not significant after treatment between the two groups (all P > 0.05). In 2 and 6 months follow-up, PRI grade in the comprehensive therapy group was superior to that of the medication group (both P<0. 05). After treatment and in follow-up, HAMD score was all reduced in the two groups (P < 0.01, P < 0.05) and the result in follow-up in the comprehensive therapy group was significant as compared with that in the medication group (all P<0. 05). After treatment, LSI-B score was increased obviously in the two groups (all P < 0.05) and the result in the comprehensive therapy group was better than that in the medication group (P < 0.05). The incidence of adverse reaction in the comprehensive therapy group was 16.7% (5/30), which was lower than 30.0% (9/30, P < 0.01) in the medication group.

CONCLUSIONThe comprehensive therapy of EA at qi streets acpoints combined with spinal regulation method achieves the long-term efficacy on PTN as compared with oral administration of CBZ in terms of the improvement of psychological condition, analgesia and life quality. It is the safe, effective and stable therapy.

The infection process of Exserohilum monoceras and alteration of cellar ultrastructure in infected barnyardgrass were observed by using scanning electron microscope and transmission electron microscope. The observation showed that the hypha began to form from the basal point of the conidia 8 hours after inoculation (HAI) and then penetrated barn-yardgrass leaves through stornata 13 HAI. The infection process finished from 24 to 26 HAI. After infected, cell membranes of the host were dramatically changed; starch particles disappeared in chloroplasts and lots of phenolic compounds occurred in the infected cells.

Objective To evaluate the effects of propofol on apoptosis and invasiveness of human lung cancer cell line A549 cells.Methods Human lung cancer cell line A549 were seeded onto 96-well plates (100 μl/well) and 6-well plates (2 000 μl/well) at a density of 2× 105 cells/ml,and cultured for24 h at 37 ℃ in 5％ CO2.The cells were randomly divided into 2 groups (n =60 each) using a random number table:dimethyl sulfoxide (DMSO) group and propofol group (group P).In group P,propofol with the final concentration of 100 μmoYL was added.In group DMSO,0.5％ DMSO with the final concentration of 0.5％ was added.At 24 h of incubation with drugs,caspase-3 expression was detected by high content screening (HCS); the expression of matrix metalloproteinase (MMP-2) was detected by Western blot analysis.At 0.5,1 and 5 h of incubation,ERK1/2 expression was also measured using Western blot analysis.Results Compared with group DMSO,the expression of caspase-3 was up-regulated,the expression of MMP-2 was down-regulated,ERK1/2 expression was up-regulated at 0.5 of incubation and down-regulated at 1 h of incubation,and no significant change was found in ERK1/2 expression at 5 h of incubation in group P.Conclusion Propofol can promote apoptosis in A549 cells and inhibit invasiveness of human lung cancer cell line A549 cells.

Methods Forty-eight adult male SD rats w ere randomly divided into four groups: sham-operation, cerebral ischemia, scutelarin+ paeoniflorin, and cyclopamine (n=12 in each group). A model of permanent middle cerebral artery occlusion w as induced by suture method. The intraperitoneal injection of cyclopamine 6 mg/kg, a specific inhibitor of sonic hedgehog (SHH) pathw ay, at 15 min before ischemia in the cyclopamine group, w hile other groups w ere intraperitoneal y injected an equal volume of saline. At 0 hour and 3 hours after ischemia, the scutel arin+paeoniflorin group and cyclopamine group w ere intraperitoneal y injected scutel arin ( 20 mg/kg ) and paeoniflorin (30 mg/kg), while other groups were intraperitonealy injected an equal volume of saline. Neurological deficit scores w ere performed at 24 hours after ischemia, and then the rats w ere decapitated. The cerebral infarct volume w as measured by using 2,3,5-triphenyltetrazolium chloride (TTC) staining. Real-time fluorescent quantitative polymerase chain reaction and Western blotting w ere used respectively to detect the expression levels of SHH, Patched-1, Gli-1 mRNAs and proteins in the ischemic cortex. Results The neurological deficit scores in the cerebral ischemia group, scutel arin+paeoniflorin group, and cyclopamine group w ere 3.33 ±0.52, 1.50 ±0.55, and 3.67 ±0.52, respectively. The neurological deficit score in the scutel arin+paeoniflorin group w as significantly low er than that in the cerebral ischemia group ( P<0.05), and the neurological deficit score in the cyclopamine group w as significantly higher than that in the scutelarin+paeoniflorin group ( P<0.05). The infarct volume percentage in the cerebral ischemia group, scutelarin+paeoniflorin group, and cyclopamine group were 31.77%±1.19%, 22.94%±2.65%, and 35.53%±0.20%, respectively. The infarct volume in the scutel arin+paeoniflorin group w as significantly less than that in the cerebral ischemia group ( P<0.05), and the infarct volume in the cyclopamine group was significantly larger than that of the scutelarin+paeoniflorin group (P<0.05). The expression levels of SHH, Patched-1, Gli-1 mRNAs and proteins in the cerebral ischemia group, scutelarin+paeoniflorin group, and cyclopamine group w ere significantly higher than those in the sham -operation group (al P<0.05). The expression levels of SHH, Patched-1, Gli-1 mRNAs and proteins in the scutelarin+paeoniflorin group were significantly higher than those in the in the cerebral ischemia group (al P<0.05), and the expression levels of Gli-1 mRNA and protein in the cyclopamine group were significantly lower than those in the scutelarin+paeoniflorin group ( al P<0.05 ). Conclusions The scutel arin combined w ith paeoniflorin has certain protective effect on focal cerebral ischemia injury in rats. Its mechanism is associated w ith the activation of SHH signaling pathw ay.
