OBJECTIVETo observe the effect differences on post-stroke dysphagia among acupoint injection combined with neural electrical stimulation, acupoint injection, neural electrical stimulation, and swallowing training respectively, so eligible intervention can be applied to this kind of disease.

METHODSOne hundred and eight-three patients of post-stroke dysphagia were randomized into a comprehensive treatment group (42 cases), an acupoint injection group (44 cases), a neural electrical stimulation group (49 cases) and a swallow training group (48 cases) and were treated with the comprehensive therapy of acupoint injection and neural electrical stimulation, acupoint injection, neural electrical stimulation and swallowing training separately. The treatments for 10 days made one session. There were 3 days at the interval among treatment sessions and 3 sessions were required totally. The cases in those treatment groups were blankly controlled with the other 47 patients of post-stroke dysphagia. All the patients received basic rehabilitation treatment. The modified water swallowing test was conducted to assess the efficacy before treatment, 10 days after treatment and 30 days after treatment in each group separately. The clinical efficacy, score of water swallowing test and improvement in water swallow test were compared among the groups.

RESULTSAfter 10-day treatment, the differences in efficacy and score of water swallow test were not significant in each group (all P > 0.05). After 30-day treatment, the effective rate (94.29%, 33/35) in the comprehensive treatment group was apparently better than 68.75% (22/32) in the acupoint injection group, 80.00% (32/40) in the neural electrical stimulation group, 67.50% (27/40) in the swallowing training group and 42.86% (12/28) in the blank group separately. The score in water swallow test in the comprehensive treatment group was lower than that in each of the other groups (1.37 ± 0.60 vs 2.03 ± 1.00, 1.90 ± 0.90, 2.20 ± 0.72, 2.71 ± 0.90, all P < 0.05). The differences in the effective rate and score in water swallow test were not significant among the acupoint injection group, neural electrical stimulation group and swallowing training group (all P > 0.05), which indicated that the improvement in swallowing function in the comprehensive treatment group was significantly superior to the other groups (all P < 0.05).

CONCLUSIONThe comprehensive therapy of acupoint injection and neural electrical stimulation achieves the much better efficacy on post-stroke dysphagia.

To study the variation of six ester-type alkaloids and characteristic fingerprints in the process from Radix Aconite Lateralis to Heishunpian and lay a foundation for the study of the processing principle of Heishunpian, HPLC. analysis was performed on a Phenomenex Gemini C18 (4.6 mm x 250 mm, 5 microm) with acetonitrile and 40 mmol x L(-1) ammonium acetate (adjusted to pH 10 with concentrated ammonia water) as mobile phase. The detection wavelength was set at 235 nm. The flow rate was set at 0.8 mL x min(-1) and the injection volume was 10-20 microL. Six ester-type alkaloids were determined and characteristic fingerprints of the process were established. As the process continues, the contents of diester diterpene alkaloids were decreased step by step, while the contents varia tion of monoester diterpene alkaloids were not obvious. Each sample showed significant difference in characteristic fingerprints. With the exception of 6 known monoester diterpene alkaloids and diester diterpene alkaloids, 13 peaks were marked in the characteristic fingerprints, of which the total change rule of the other 7 unknown peaks were similar with 3 diester diterpene alkaloids. The established method is accurate, reliable and repeatable, and can provide reference for revealing change rule of index components and illuminating processing principle in the process of Heishunpian.

OBJECTIVETo explore the role of nasal mucosal lymphatic drainage in the pathogenesis of nasal polyps.

METHODSThere were 25 cases in the experimental group who had nasal polyps (which was further divided into Malm-1, Malm-2, Malm-3 level 3 subgroups) and 6 cases in the control group, including thyroid cancer and laryngeal cancer patients who had normal nasal structure. The nasal polyps in the experimental group and the middle turbinate in the control group were injected with a radionuclide and a radionuclide imaging technique was used to image the nasal mucosal lymphatics. The lymphatic drainage status of the nasal mucosa through the imaging results was analysed.

RESULTSThe T/NT ratio (radioactivity counting) of the region of interest (ROI) was 20. 66 +/- 1.89 in the control group and 29. 33 +/- 6.34 in the experimental group. The difference was significant (t = 3.275, P < 0.05). The T/NT ratio of the ROI was 24.40 +/- 3.19 in the Malm-1 level group, 29.31 +/- 3.39 in the Malm-2 level group, 39.21 +/- 3.15 in the Malm-3 level group. The differences of qualitative analysis were significant (F = 38. 980, P < 0.05). The quantitative analysis showed that at the injection site, signs of lymphatic development and drainage were not found in the control group or experimental group, but the phenomenon of contrast media retention existed at the injection site in the experimental group.

CONCLUSIONLymphatic drainage dysfunction exists in patients with nasal polyps, and it may play a role in the pathogenesis of nasal polyps.

OBJECTIVETo explore whether there exists coincidence of the most appearing time of clinical features of liver cancer at different longitude and latitude, according to the law of field equation and the theory of warpage of space time by Einstein.

METHODSThree regions with different longitude and latitude were selected randomly and sampled. There were 36 items altogether, including 12 clinical items, which were used to imitate the yearly cycle cosine curve. The acorphases and the ratioes of amplitudes and means were compared to justifying whether they were in the same range.

RESULTSAll the acorphases of 36 items appeared between -90.1degrees to -207.5 degrees (from april to july), existing in one third of the same range, in which 13 items occurred rhythmly (P<0.05). The image acorphases of liver cancer at the early and middle stage and gamma-glutamyl transpeptidase acorphase appeared between -98.5 degrees to -148.2 degrees (from april to may), in which 5 items occurred rhythmly (P<0.05).

CONCLUSIONIt is the same mode of the yearly biologcal cycle for liver cancer malignant growth within the most appearing time (from april to july). It will increase the detecting rate of liver cancer at the early and middle stage during this time (especially from april to may).

Objective To investigate the carrier ratio and the genotype of thalassemia among students of secondary school in Chongzuo, Guangxi. Methods From June 10-20,2008 among 7 regions of Chongzuo, 1 secondary school was randomly chosen from each region, and the number of student volunteers was determined by 0.5‰ proportion of the local population size. 1097 students were screened, including 515 boys and 582 girls of 12-16 year olds. Among them, 968 cases were Zhuang (438 boys and 530 girls) 128 cases were Han (76 boys and 52 girls) and one case was Yao nationalities (boy). Analysis of blood cells was detected by Cell Dyn 1700 automatic hemocyte analysator while hemoglobin F (HbF) and hemoglobin A2 (HbA2) were detected by hemoglobin autoanalyse variant. Among those with HbA2≥ 4% that belonged to β-thalassemia before α and β-thalassemia gene were analyzed to identify the genotypes. IfHbA2 was <4% but MCV≤80 fl, α-thalassemia gene was analyzed. Results Among 1097 cases,218 wereα-thalassemia (19.87%), 50 were β-thalassemia (4.56%) and 13 were combination of α β-thalassemia (1.19%). The overall detected ratio was 25.62%. 133 cases with thalassemia were boys (25.83%) and 148 were girls (25.43%) with no significant difference(P>0.05). 255 cases of thalassemia were Zhuang (26.34%), and 25 were Han nationality (19.52%). The detected ratio among Zhuang nationality was higher than in Hun nationality and with significant difference statistically (P<0.01). 3 kinds of deletion (-α3.7/,-α<4.2>/, --SEA/) and another 3 kinds of non-deletion (αα CS/, αα WS/, αα QS/) α-thalassemia genotype were identified, with a higher rate of ααWS/. Among the β-thalassemia genotype, CD41-42 appeared the most common genotype. MCV of thalassemia was lower than in the controls, with significant difference (P<0.01). 78-90 fl of α-thalassemia was detected from the MCV specimen. If taken MCV<79 fl as the positive phenotype of thalassemia, 32 cases were misdiagnosed. The rate of missed diagnosed cases was 2.97%. Conclusion Rate of thalassemia carder among students of secondary school in Chongzuo, Guangxi was considered to be high, especially those belonged to Zhuang nationality were higher than the Hans. The carrier rate of ααWS/was higher, with CD41-42 the most common genotype.
