Objective To study the therapeutic effect of intravitreal injection of ranibizumab combined with vitrectomy for the treatment of neovascular glaucoma (NVG). Methods The clinical data of 21 NVG patients who had underwent vitrectomy were retrospectively analyzed. The patients were treated with intravitreal injection of ranibizumab 0.5 mg, then were given the vitrectomy after 3 to 5 d after treatment. The whole retinal photocoagulation was performed during the operation. Cataract surgery was combined in 16 patients, and ciliary photocoagulation was combined in another 15 patients. All patients were followed up for 6 to 12 months, and the intraocular pressure, visual acuity and neovascularization of iris (NVI) were observed. Results The rate of NVI symptoms resolving completely 3 weeks after operation was 80.95％(17/21). The intraocular pressure 1 week, 1 month, 3 months and 6 months after operation was significantly lower than that before operation: (18.6 ± 5.1), (14.3 ± 4.8), (12.8 ± 4.4), (15.1 ± 3.7) mmHg (1 mmHg=0.133 kPa) vs. (42.8 ± 7.3) mmHg, and there was statistical difference (P<0.05). Two months after operation, 2 cases were not able to control by chemicals, and were treated with transscleral cyclophotocoagulation. Six months after operation, the intraocular pressure was completely controlled in 15 cases, and conditionally controlled in 6 cases. No ocular hypotension occurred. The visual acuity was not improved in 4 cases, but the rest were improved in different degrees. Conclusions For the patients of NVG combined with vitreous hemorrhage and obvious proliferation, intravitreal injection of ranibizumab in the first place, and then combined with vitrectomy, whole retinal photocoagulation and ciliary photocoagulation can obtain good effect.

Abstract: Objective To explore and analyze the diagnostic value of multicolor melting curve analysis (MMCA) for the resistance of five anti-tuberculosis drugs, so as to clarify the clinical value of MMCA in detecting drug resistance of Mycobacterium tuberculosis. Methods From April 2021 to May 2022, 200 patients with positive Mycobacterium tuberculosis admitted to the Fourth People's Hospital of Qinghai Province were selected as research objects, and sputum specimens were taken from the patients. Traditional Mycobacterium tuberculosis drug sensitivity test (modified Löwenstein-Jensen medium method) and MMCA analysis were respectively given to detect the resistance of five anti-tuberculosis drugs, including isoniazid, ethambutol, streptomycin, rifampicin and isoniazid, respectively. Those samples with inconsistent results between the two diagnosis methods were subjected to gene sequencing verification, and the diagnosis efficiency of MMCA for the five anti-tuberculosis drugs was compared. Results Using Mycobacterium tuberculosis drug sensitivity as the gold standard for drug resistance diagnosis, the sensitivity of MMCA for detecting drug resistance of rifampicin, ethambutol, streptomycin, isoniazid and levofloxacin were 95.83% (46/48), 93.75% (15/16), 100.00% (15/15), 100.00% (20/20) and 70.00% (7/10), respectively, with statistical differences between groups (P<0.05). There were no statistically significant differences in the specificity, positive predictive value, negative predictive value and accuracy of MMCA for the five anti-tuberculosis drugs (P>0.05). For the 8 samples with inconsistent results between MMCA and modified Löwenstein-Jensen medium method, gene sequencing was performed and compared with the results of gene sequencing. After comparison with gene sequencing results, it was found that the coincidence rate of MMCA and gene sequencing results was 75.00% (6/8). Conclusions In the detection of drug-resistant mutations in TB patients, multi-color probe fusion curve analysis has high diagnostic efficacy for first-line anti-tuberculosis drugs, but is not sensitive to second-line anti-tuberculosis drug levofloxacin. Therefore, for the detection of first-line anti-tuberculosis drugs, MMCA has a good clinical application prospect.

OBJECTIVETo explore the effects of thyroid hormone on the expression of homeobox gene Nkx2.1 mRNA in child rat by supplying their hypothyroidism pregnant mother with different dose of levothyroxine (L-thyroxine, L-T(4)) in different times.

METHODS120 female Wistar rats were randomly divided into eight groups according to the body weight: control group, non-treatment hypothyroidism group, hypothyroidism groups supplied with L-T(4) in high, medium and low dosage in early stage (1st-17th day of pregnancy) and in late stage (18th day of pregnancy-20th day after childbirth). According to 100 grams of body weight, the concentrations of L-T(4) were 3.5, 2.0, 0.5 µg/d in high, medium and low dosage group. All the rats were fed with low-iodine food. The control group was given 200 µg/L potassium iodate solution as drinking water and the other groups were given deionized water. After three months, the rats were mated with normal male rats. After the pregnancy was confirmed, hypothyroidism groups were supplied with L-T(4) of different concentrations. Brain samples were taken from the 17-day fetal rats, new-born and 20-day old offsprings and the levels of Nkx2.1 mRNA in brain tissue were analyzed by real-time fluorescence quantitative PCR techniques.

RESULTSThe levels of TT(3) in hypothyroidism groups supplied with L-T(4) in high, medium and low dosages in early and late pregnant stages, non-treatment hypothyroidism group and control group were (0.85 ± 0.17), (0.81 ± 0.18), (0.86 ± 0.21), (0.85 ± 0.20), (0.89 ± 0.18), (0.85 ± 0.20), (0.86 ± 0.20), (1.08 ± 0.07) nmol/L (F = 4.08, P < 0.01); the levels of TT(4) in each group were (0.43 ± 0.16), (0.39 ± 0.11), (0.39 ± 0.13), (0.43 ± 0.17), (0.51 ± 0.19), (0.43 ± 0.16), (0.41 ± 0.15), (39.43 ± 14.16) nmol/L (F = 31.99, P < 0.01); the levels of FT(3) in each group were (3.29 ± 0.61), (3.29 ± 0.61), (3.24 ± 0.61), (3.28 ± 0.63), (3.31 ± 0.59), (3.28 ± 0.50), (3.24 ± 0.49), (4.93 ± 0.46) pmol/L (F = 5.79, P < 0.01); the levels of FT(4) in each group were (3.38 ± 0.80), (3.31 ± 0.67), (3.29 ± 0.73), (3.27 ± 0.71), (3.48 ± 0.81), (3.56 ± 0.66), (3.29 ± 0.61), (27.29 ± 4.53) pmol/L (F = 26.34, P < 0.01). The expression of Nkx2.1 mRNA in non-treatment hypothyroidism group (9.15 × 10(-5) ± 9.17 × 10(-5)) was lower than control group (65.1 × 10(-5) ± 40.90 × 10(-5)) in 17th day of pregnancy (t = 66.224, P < 0.05); the expression of Nkx2.1 mRNA in non-treatment hypothyroidism group (3.16 × 10(-5) ± 0.142 × 10(-5)) was lower than control group (55.6 × 10(-5) ± 51.05 × 10(-5)) in new-born (t = 102.225, P < 0.05); the expression of Nkx2.1 mRNA in non-treatment hypothyroidism group (8.09 × 10(-5) ± 8.21 × 10(-5)) was lower than control group (13.9 × 10(-5) ± 7.43 × 10(-5)) in 20th day after birth (t = 9.235, P < 0.05). The trend of Nkx2.1 mRNA in hypothyroidism groups was decreased in group supplied with L-T(4) in medium dosage in early stage descends in 17th day of pregnancy, new-born and 20th day after birth (57.1 × 10(-5) ± 22.90 × 10(-5)), (30.8 × 10(-5) ± 27.20 × 10(-5)), (17.1 × 10(-5) ± 0.623 × 10(-5)) (F = 13.394, P < 0.01). The expression of Nkx2.1 mRNA in hypothyroidism groups supplied with L-T(4) in medium dosage in early stage in 17th day of pregnancy, new-born and 20th day after childbirth was closest to the control group in every period (t values were 0.225, 0.336, 0.345, all P values > 0.05).

CONCLUSIONThe difference in the expression of homeobox gene Nkx2.1 mRNA is highly related to the level of thyroid hormone.

OBJECTIVETo study the association of fibrinogen(Fg) B beta -854G/A, -455G/A, -249C/T, -148C/T, 448G/A and Bcl-1G/A gene polymorphisms with factors affecting obesity, and the fibrinogen function such as plasma fibrinogen concentration and molecular reactivity.

METHODSOne thousand and three hundred ninety-one subjects from Kailuan corporation were enrolled by medical examination and questionnaire survey, and were divided into normal weight, overweight and obese groups based on body mass index (BMI). Blood biochemistry, fibrinogen concentration, fibrin monomer polymerized velocity (FMPV), and FMPV/A(max) were measured. The gene polymorphisms of the six loci were detected by polymerase chain reaction-restriction fragment length polymorphism.

RESULTSThe frequencies of Bcl-1A and its mutated genotype in the overweight group were significantly higher than that in the normal weight group (P< 0.01). In all the three groups, Fg concentration, FMPV, FMPV/A(max) in individuals with B beta -854 mutated genotype were significantly higher than those with wild type genotype (P< 0.01), and in the overweight group, FMPV/A(max) in those with B beta -455 mutated genotype, FMPV in those with B beta -249 mutated genotype, were higher than those with wild type genotype (P< 0.05).

CONCLUSIONIndividuals with Bcl-1A and its mutated genotype are susceptible to overweight. The B beta -455 and -249 mutated genotypes are accumulative genes for overweight by regulating the Fg function.

OBJECTIVETo study the distribution characteristics of Beta-fibrinogen (Fg)B gene-854G/A, -455G/A, -249C/T, -148C/T, 448G/A and Bcl-1 G/A polymorphism in North China Han population, and the influence on plasma Fg concentration and molecular reactivity. Further more, to explore the role of Fg gene polymorphisms combining with multi-physiological and environmental factors in the development of cerebral infarction.

METHODSCluster sampling, health examination and questionnaires surveys of 1652 subjects from Tangshan Kailuan Group Corporation were conducted. Blood biochemistry, Fg concentration, fibrin monomer polymerized velocity (FMPV), absorbance maximum (Amax) and FMPV/Amax were measured. The six polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism.

RESULTSIn the population, the proportion of the FgB beta-249 T variation allele was 65.49%, while the proportion of the rest loci was predominantly wild type. The significant differences in Fg concentration and FMPV/Amax were found in -854 genotype groups. The Fg concentration in -854GA group was higher than those in GG and AA group. Only the distribution frequencies of FgB beta Bcl-1 A variation allele, GA and AA genotype in the cerebral infarction group were higher than those in non-infarction group, and the prevalence of cerebral infarction in AA genotype group was higher than other groups (the probability value of above-mentioned results were all P<0.01).

CONCLUSIONSFgB beta Bcl-1A allele and variation genotype were susceptible to cerebral infarction. FgB beta-455GA/448G linkage genotype may contribute to the increased plasma Fg concentration. FgB beta-854 was one of the main controlling gene loci for plasma Fg concentration and molecular reactivity.
