Objective To observe the clinical efficacy of acupoint injection plus nerve electrical stimulation in treating deglutition disorders after cerebral stroke. Method Seventy-seven patients with deglutition disorders after cerebral stroke were randomized into an electrical stimulation group of 24 cases, a hydroacupuncture group of 26 cases, and a comprehensive group of 27 cases, to respectively receive Vitalstim electrical stimulation, acupoint injection of Mecobalamin, and both of the treatments, 5 d as a treatment course, with 2-day interval between two courses, for 4 courses in total. The modified water-drinking test and Standardized Swallowing Assessment (SSA) were adopted to evaluate the therapeutic efficacy before the intervention, after 20-day treatment, and after 60-day treatment, and the therapeutic efficacies were compared. Result The modified water-drinking test and SSA scores were significantly changed in the three groups after 20-day treatment compared with that before the intervention, and the scores in the comprehensive group were superior to that of the electrical stimulation group and hydroacupuncture group. However, on the 60th day, the scores were equivalent among the three groups. Conclusion The Vitalstim electrical stimulation and acupoint injection of Mecobalamin both can produce certain treatment effects for deglutition disorders after cerebral stroke;the two methods can work in a synergistic way and can boost the improvement of swallowing function.

Objective To identify potential serum biomarkers specific for hepatocellular carcinoma (HCC).Methods Eighty-one patients wilh hepatitis B-related HCC and 80 healthy controls were randomly divided into a training set (48 HCC,47 controls) and a testing set (33 HCC,33 controls).Serum proteomic profiles were measured using surface-enhanced laser desorption/ionization time-offlight mass spectroscopy (SELDI-TOF-MS).A classification tree was established by the Biomarker Pattern Software.Candidate biomarkcrs were separated by HPLC and identified by MA1DI-MS/MS and database searching.Forty-eight patients with HCC,54 cirrhotic patients and 42 healthy subjects were clinically validated using candidate biomarkers by SELDI-Immunoassay.Real-time reverse transcriptase-polymerase chain reaction was performed to observe GRO-1 and Thrombin in 55 HCC tissues and 13 normal hepatolage tissues.Results Two up-regulated protein peaks were automatically chosen as a classification tree in the training set.These biomarkers were identified as thrombin light chain and CXC chemokines ligand 1 (GRO-1).The sensitivity and specificity of this classification tree were 89.6％.The multivariate model using the two biomarkers and alpha-fetoprotein (AFP) resulted in a sensitivity of 91.7％ and specificity of 92.7％,which was significantly better than AFP alone.The mRNA expression of GRO-1 and Thrombin were found in all HCC tissues.There were significant associations between GRO-1 gene expression and some clinical and pathological findings such as metastasis and recurrence (P＜0.05).Significant differences of 5-year survival rates wee observed among subgroups according to the expression of GRO-1 (P＜0.05).There were significant associations between Thrombin gene expression and some clinical and pathological findings such as recurrence and AFP (P＜0.05).Significant differences of 5-year survival rates were observed among the subgroups according to the expression of THROMBIN (P＜0.05).A positive correlation was found between GRO-1 and Thrombin (r=0.73,P＜0.01).Conclusion Thrombin light chain and GRO-1 are potential biomarkers of HCC.The expression of GRO-1 in HCC tissues was a valuable indicator in estimating metastasis and recurrence in HCC patients.

Objective To evaluate the impact of different treatment strategies on patients with hepatocellular carcinoma (HCC) of less than 10 cm but with portal vein tumor thrombus (PVTT),and to investigate the prognostic factors.Methods Between 2003 and 2008,338 HCC patients with PVTT from the Affiliated Tumor Hospital,Guangxi Medical University,were retrospectively studied.These patients were divided into four groups:the conservative treatment group (n =75),the transarterial chemoembolization (TACE) group (n=86),the surgical resection group (n =90) and the surgical resection with postoperative TACE group (n=87).Survival rates were analyzed by the Kaplan-Meier method and differences among groups were compared using the log-rank analysis.The Cox' s proportional hazards model was performed to explore the risk factors of survival.Results The mean survival periods of patients in the four groups were 3.8,7,8.2,15.1 months respectively.There were significant differences in survival rate among the 4 groups.The survival rates at 1-,2-,and 3-year in the surgical resection with postoperative TACE group were 49％,37％ and 19％,which were significantly higher than the other 3 groups (P＜0.05).The 1-,2-,and 3-year survival rates in the surgical resection group were 28％,20％ and 15％ compared with 17.5％,0％ and 0％ in the TACE group.The survival rates were significantly higher after surgical resection than TACE (P＜0.05).The 1-,2-,and 3-year survival rates in the conservative treatment group were 0％.These were the lowest among the four groups (P＜0.05).Univariate analysis indicated that portal vein occlusion by tumor thrombus was a significant predictor of poor prognosis.Multivariate analysis revealed that the strategy of treatment (TACE) and the number of TACE cycles were independent survival predictors for HCC patients with PVTT.Conclusions Surgical resection is the most effective therapeutic strategy for HCC patients with PVTT and with good liver functional reserve.Postoperative TACE is necessary in preventing recurrence and prolonging survival in patients who could tolerate chemoembolization.TACE should be recommended as an effective and safe treatment for unresectable HCC patients with PVTT.The treatment provided a significantly better survival than conservative treatment.

Objective To investigate the efficacy of laparoscopic hepatectomy for the treatment of hepatocellular carcinoma (HCC).Methods The clinical data of 30 HCC patients who were admitted to the Affiliated Cancer Hospital of Guangxi Medical University from January 2011 to December 2011 were retrospectively analyzed.All patients were divided into the laparoscopic hepatectomy (LH) group (10 patients) and open hepatectomy (OH) group (20 patients) according to the operation patterns and at the ratio of 1 ∶ 2.The degree of cirrhosis,size and location of tumor of the 2 groups were analyzed using the covariance analysis.The student t test was used for analysing the difference of the 2 groups.Results In the LH group,7 patients received laparoscopic nonanatomical liver resection,3 received anatomical resection of the left lateral lobe,no patient was converted to the hand assisted laparoscopic surgery or open surgery.In the OH group,14 patients received non-anatomical liver resection,and 6 received anatomical liver resection.The volume of blood loss of the LH group was (247 ± 235) ml,which was significantly lower than (408 ± 191)ml of the OH group (t =2.199,P ＜ 0.05).The mean postoperative fasting time,postoperative abdominal drainage time and duration of hospital stay of the LH group were (1.9 ±0.6) days,(3.2 ± 1.2) days and (8.9 ± 2.3) days,which were significantly shorter than (3.0 ± 1.6) days,(4.9±1.6)daysand (11.5±2.3)days of the OH group (t=2.149,2.917,2.921,P＜0.05).The levels of alanine aminotransferase (ALT) of the LH group at day 1,3,5 were (228 ± 100)U/L,(143 ± 51)U/L,(85 ±24) U/L,and the levels of aspartate aminotransferase (AST) of the LH group at day 1,3,5 were (196 ± 67)U/L,(90 ± 35) U/L,(46 ± 10) U/L.The levels of ALT of the OH group at day 1,3,5 were (557 ± 401) U/L,(414 ±397)U/L,(217 ± 199)U/L,and the levels of AST of the OH group at day 1,3,5 were (506 ±317)U/L,(178 ± 122) U/L,(71 ± 33) U/L.The time for hepatic function recovery of the LH group was significantly shorter than that of the OH group (t =3.675,3.001,2.073 ; 4.196,2.223,2.272,P ＜ 0.05).All the 30 patients were followed up for 3-15 months.The level of alpha fetoprotein of 1 patient in the LH group was increased at postoperative month 4,and the results of computed tomography showed multiple intrahepatic lesions.The patient was cured by intervention treatment.One patient of the OH group was diagnosed as with tumor recurrence at the resection margins and adjacent hepatic segments.The patient was cured by radiofrequency ablation,with no tumor recurrence.No tumor recurrence or metastasis was observed in the other patients.Conclusion Laparoscopic hepatectomy is a feasible,safe and minimally invasive approach for patients with HCC.

Objective To analyze the prognostic factors of survival in patients with huge hepatocel lular carcinoma (HCC) who underwent hepatectomy with a view to improve treatment efficacy.Methods A retrospective study was conducted on 124 patients with huge hepatocellular carcinoma who underwent hepatectomy for HCC from January 2004 to December 2010 in our hospital.Univariate and multivariate analyses were performed using statistical software (SPSS 19.0 for Windows) to identify independent prognostic factors.Results The cumulative 1-,3-and 5-year survival rates of the 124 patients were 65.1％,35.8％ and 25.1％ respectively.The mean survival and the median survival were 34.7 and 26.0 months respectively.In the 65 patients who underwent curative resection,the 1-,3-and 5-year disease-free survival rates were 40.2％,19.3％ and 7.1％ respectively.The mean disease-free survival and the median disease-free survival were 18.6 and 9.0 months respectively.Univariate analysis showed HBsAg,tumor capsule,liver cirrhosis,vascular invasion,tumor rupture,intrahepatic metastasis,curative resection and BCLC staging significantly affected postoperative survival(P ＜ 0.05).The Cox multivariate analysis indicated HBsAg,liver cirrhosis,curative resection and intrahepatic metastasis were independent prognostic factor (P ＜ 0.05).Conclusions Intrahepatic metastasis,liver cirrhosis and HBsAg were prognostic factors influencing survival outcome of huge HCC in patients after hepatectomy.Improving curative resection rate of huge HCC significantly extended survival for these patients.

Objective To explore the association between ratio index of gamma glutamyl transpeptidase/platelet (GPRI) and the prognosis of patients with hepatitis B virus (HBV) related hepatocellular carcinoma (HCC) before liver resection. Methods A total of 368 patients underwent liver resection for HBV-related HCC were retrospectively analyzed in this study. Patients were divided into high GPRI group (n=184, GPRI≥0.38) and low GPRI group (n=184, GPRI<0.38). Clinicopathologic characteristics including overall survival (OS) and disease-free survival (DFS) were compared between the two groups. Independent risk factors influencing DFS and OS were determined by Cox multivariate analysis. Results Compared to low GPRI group, there were higher levels of serum total bilirubin and alanine aminotransferase, higher proportions of tumor diameter larger than 10 cm, amount of tumou more than 3, and patients with macrovascular invasion and intermediate or advanced HCC in high GPRI group (all P<0.05). Values of DFS at 1, 3, and 5 years were significantly lower in high GPRI group (50.8%, 16.9%and 5.7%) than those in low GPRI group (69.0%, 33.3%, 10.7%;P=0.001). Values of OS at 1, 3, and 5 years were also significantly lower in high GPRI group (75.0%, 51.8%and 36.0%) than those in low GPRI group (89.8%, 72.8%and 63.2%;P<0.05). Cox multivariate analysis also demonstrated that GPRI ≥0.38 was an independent risk factor for DFS and OS in patients with HBV-related HCC after liver resection. Conclusion Preoperative GPRI can predict tumor recurrence and long-term survival in patients with HBV-related HCC after liver resection.

Objective:To investigate the effect of metoprolol tartrate combined with atorvastatin calcium on lipid metabolism, vascular endothelial function and inflammatory factors in patients with essential hypertension.Methods:From January 2015 to December 2018, 80 patients with essential hypertension admitted to the People's Hospital of Dongyang were divided into observation group (40 cases) and control group (40 cases) according to the random digital table method.On the basis of routine treatment, the control group was treated with atorvastatin calcium, while the observation group was treated with atorvastatin calcium and metoprolol.The course of treatment in both two groups was 6 months.The changes of systolic and diastolic blood pressure, lipid metabolism, endothelial function and inflammatory factors were compared before and after treatment.Results:The total effective rate of the observation group (92.50%, 37/40) was higher than that of the control group (70.00%, 28/40) (χ 2=6.646, P<0.05). The systolic blood pressure [(123.15±7.89) mmHg] and diastolic blood pressure [(75.52±3.89)mmHg] in the observation group were lower than those in the control group [(134.29±10.31)mmHg and (82.31±4.04)mmHg] ( t=5.427, 7.657, all P<0.05). The level of serum NO [(69.74±5.46)nmol/L] in the observation group was higher than that in the control group [(57.87±3.67)nmol/L], while ET-1 [(56.48±5.49)mg/L] in the observation group was lower than that in the control group [(73.24±7.18)mg/L], the differences were statistically significant( t=11.411, 11.728, all P<0.05). The serum levels of CRP [(1.18±0.23)mg/L], TNF-α [(0.63±0.18)μg/L] and IL-6 [(84.35±17.28)ng/L] in the observation group were lower than those in the control group [(1.64±0.45)mg/L, (1.23±0.26)μg/L and (128.43±19.86)ng/L] ( t=5.757, 12.000, 10.590, all P<0.05). Conclusion:Metoprolol tartrate combined with atorvastatin calcium is effective in the treatment of essential hypertension, and can improve lipid metabolism, vascular endothelial function, and reduce inflammation.

OBJECTIVE To study the absorption characteristics of phenylpropanoids of Mongolian medicine Tabson-2 decoction(TBD) in Caco-2 cells and to preliminarily clarify the oral absorption mechanism of TBD. METHODS Caco-2 cell monolayer model was used to analyze the uptake components of TBD in Caco-2 cells by UPLC-MS/MS, and UPLC-MS/MS analysis method was established to determine the nine best absorbed components of TBD, protocatechuic acid, neochlorogenic acid, chlorogenic acid, cryptogenic acid, 1,5-dicaffeinate quinic acid, isochlorogenic acid C, caffeic acid, dihydrocaffeic acid, chlorogenic acid. The effects of time, concentration and P-glycoprotein inhibitor on the absorption of each component were investigated. RESULTS The overall intake of caffeic acid and dihydrocaffeic acid showed an upward trend in 0-180 min, and did not show saturation. The absorption of 3-hydroxycinnamic acid was constant at about 90 min and tended to saturation. The intakes of cryptochlorogenic acid, 1,5-dicaffeinate, quinic acid, isochlorogenic acid C, neochlorogenic acid, chlorogenic acid and protocatechuic acid first decreased and then increased with time from about 90 min. The addition of P-glycoprotein inhibitor verapamil and cyclosporin A had an effect on the absorption of dihydrocaffeic acid compared with the phenylpropanoid components, indicated that dihydrocaffeic acid was the substrate of P-glycoprotein. CONCLUSION The main phenylpropanoids of TBD enter Caco-2 mainly by passive diffusion, supplemented by active transport, and the absorption process of the other eight components is not affected by the efflux of P-glycoprotein except dihydrocaffeic acid.

Objective:To observe any effect of low-frequency whole body resonant stimulation on the ba-lance and walking ability of hemiplegic stroke survivors.Methods:Sixty-six stroke survivors with hemiplegia were randomly divided into a low-frequency resonance training group, a high-frequency vibration training group and a control group, each of 22. All received routine exercise training at individualized intensities. All three groups underwent five 1-minute cycles of 7Hz, 15Hz or 1Hz stimulation twice a day, five days a week for eight weeks. Before and after the intervention, balance and walking ability were evaluated using the Berg Balance Scale, the timed up and go test and a 10m walking test. Step length, step frequency and step speed were also measured.Results:There were no significant differences among the three groups before the training. Afterward, significant improvement was observed in all of the groups in terms of all of the measurements. The average results of the low-frequency resonance training group were at that point significantly better than the other two groups′ averages, while the high-frequency vibration training group′s results were superior to those of the control group.Conclusion:Resonance training at 7Hz is the most effective in improving the balance and walking ability of stroke survivors with hemiplegia.
