OBJECTIVETo explore the changes of peripheral blood lymphocyte subsets in patients with acute hydrogen chloride gas poisoning.
METHODSWhen the patients were admitted or on the secondary day, the percentages of total T-cell lymphocyte subsets (CD(3)(+)CD(19)(-)), CD(4)(+)T cells (CD(3)(+)CD(4)(+)), CD(8)(+)T cells (CD(3)(+)CD(8)(+)), B cells (CD(3)(-)CD(19)(+)) and NK cells (CD(3)(-)CD(16)(+)CD(56)(+)), and the ration of CD(4)(+)/CD(8)(+) in 37 cases with acute hydrogen chloride gas poisoning and 49 healthy controls were detected with flow cytometer.
RESULTSThe total T-cell percentage and total CD(4)(+)T cell percentage in 37 cases were significantly lower than those in 47 controls (P < 0.05). The percentages of NK cells and B lymphocytes in 37 cases significantly increased, as compared with controls (P < 0.05). The ration of CD(4)(+)/CD(8)(+) in 37 cases significantly decreased, as compared with controls (P < 0.05).
CONCLUSIONThe lymphocyte subsets in the patients with acute hydrogen chloride gas poisoning changed, which could influence the immune function of patients.

By non-steady method,the effective diffusivity of ferrous sulphate within alginate calcium gel entrapped without bacteria was measured.Meanwhile the oxidation ability of entrapped bacteria was analyzed.Experimental results showed that the effective diffusion coefficient of ferrous sulphate decreased with the increase of alginate concentration,the optimum alginate concentration is 2%(W/V).The effect of calcium chloride on the effective diffusivity was neglectable.The incubation of ferrooxidans would pass through 10 hours,and the diffusion coefficient within gel entrapped Thiobacillus ferrooxidans cells was less remarkably than that of ferrous sulphate without entrapped cells.For the entrapped cells,the absolute oxidation time was shortest and the rate change was fastest with the initial Fe concentration 5g/L.The absolute oxidation time was same when the initial Fe concentration was 8g/L and 10g/L.

The effect of C-terminal region residues on the substrate specificity of a novel cyclic imide hydrolase (CIH), a recombinant cyclic imide hydrolase (CIH293), and its mutants deleted or substituted at C-terminus (CIH291, CIH290, KK292-293EE) was reported. The substrate specificity and kinetic parameters of the mutants were analyzed by both the spectrophotometric assay and high-performance liquid chromatography. Results show that the substrate specificity of mutants was not obviously changed, but slightly low for the affinity between the substrate and enzyme, compared with the wild-type enzyme, CIH293. In conclusion, the last three residues of CIH293 play an important role for the enzyme activity.

Objective: To observe the clinical efficacy of herb-partitioned spreading moxibustion at Baliao points plus climen for diminished ovarian reserve (DOR). Methods: A total of 60 patients with DOR were randomized into a spreading moxibustion group and a Western medicine group by the random number table method, with 30 cases in each group. The Western medicine group was treated with climen, starting from the 5th day of the menstrual cycle for 21 d. The spreading moxibustion group was treated with herb-partitioned spreading moxibustion at Baliao points on the basis of the medication in the Western medicine group, 1 h per time, once a week. The treatment was performed for 1 month as one treatment course in both groups, for 3 courses in total. The serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in the patients were measured before and after treatment. The peak systolic velocity (PSV) and resistance index (RI) were also detected. The traditional Chinese medicine (TCM) symptom score was evaluated. The clinical efficacy was evaluated after treatment. Results: The total effective rate in the spreading moxibustion group was 93.3%, which was significantly higher than 80.0% in the Western medicine group, and the difference between the groups was statistically significant (P<0.05). After treatment, the TCM symptom scores, the serum FSH levels, FSH/LH ratios and RI in both groups decreased, and the intra-group differences were all statistically significant (all P<0.05). The serum E2 level and PSV increased compared with those in the same group before treatment, and the intra-group differences were statistically significant (all P<0.05). After treatment, the TCM symptom score, the serum FSH level, FSH/LH ratio and RI in the spreading moxibustion group were lower than those in the Western medicine group, while the serum E2 level and PSV were higher than those in the Western medicine group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Herb-partitioned spreading moxibustion at Baliao points plus climen can produce valid therapeutic efficacy for DOR. It can improve the clinical symptoms, regulate serum hormone levels and increase ovarian blood perfusion, thus improving ovarian reserve function, producing more significant efficacy than climen alone.

OBJECTIVE:
To study the characters of oscillatory potentials (OPs) of electroretinogram (ERG) after methanol intoxication in rats.
METHOD:
The SD rat models of methanol intoxication were established and divided into control group, 3-day intoxication group, 7-day intoxication group. The changes of OPs of ERG were recorded in a dark room.
RESULTS:
The total amplitudes of 3-day and 7-day intoxication groups decreased approximately 50% compared with that of the control group, while the schedule delayed approximately 16% and 61%, respectively.
CONCLUSION
The characters of methanol intoxication in rats included delay in schedule and decline in the total amplitude of OPs.

alphaB-crystallin is the structural protein of vertebrate lens, which is widely expressed in non-lens tissue. As one of the heat shock protein family members, alphaB-crystallin possesses biological properties of molecular chaperones and anti-apoptotic effects. Multi-factor injuries, such as retinopathy, inflammation and nervous system diseases, have a closely relationship with alphaB-crystallin. This paper reviews the research progress of the expression and mechanism of alphaB-crystallin in retina and extraocular tissues and organs.

OBJECTIVE:
To compare the correlation between contrast vision (LV) and sweep visual evoked potential acuity (SVEP-A) among people with emmetropia, mild myopia, and moderate myopia.
METHODS:
The CV and SVEP-A were tested individually in 96 eyes from healthy young volunteers, including 37 eyes of emmetropia, 27 eyes of mild myopia, and 32 eyes of moderate myopia. The statistic analysis was done by ANOVA analysis and rank sum test.
RESULTS:
(1) With the decrease of contrast, CV and SVEP-A decreased in every group. (2) At 100% contrast, the difference of CV between emmetropia and mild myopia had statistical significance (P<0.05). At 100%, 25% and 10% contrast, the difference of CV between emmetropia and moderate myopia had statistical significance (P<0.05). (3) In the same group, the difference of 100% and 25% contrast had statistical significance (P < 0.05). So was between 100% and 10% contrast. (4) At 100% and 10% contrast, the difference of CV and SVEP-A had statistical significance (P < 0.05).
CONCLUSION
The CV of myopia relates to many factors including ametropia and fundus lesions. The correction of ametropia is important to the values of CV and SVEP-A.
