OBJECTIVETo observe the therapeutic effects of Berberine Capsule (BC) on patients with mild hyperlipidemia.
METHODSTotally 102 mild hyperlipemia patients were recruited. All patients were suggested to have proper diet and physical activity as basic therapy for 1 month of run-in period. Totally 97 patients completed it. Then they were randomly assigned to the berberine group (the treatment group, 49 cases) and the placebo group (the control group, 48 cases). Patients in the treatment group took BC 300 mg, while those in the control group took placebo 300 mg, thrice per day for 3 successive months. Then placebos and BC were interrupted for 2 months (as washout period). All subjects received only diet control and physical activity during washout period. After washout period, placebos and BC were re-administered to all patients in the same way for 3 months. Body mass index (BMI), fasting plasma glucose (FPG), TG, TC, LDL-C, and HDL-C were assessed after run-in period, washout period, at month 1, 2, 3 after the first therapy, at month 1, 2, 3 after second treatment, respectively.
RESULTSCompared with the end of run-in period, TG, TC, and LDL-C decreased, and HDL-C increased in the treatment group (P < 0.05) after first 3 months of treatment. Compared with 3 months after the first therapy, TG, TC, and LDL-C increased and HDL-C decreased in the treatment group after washout period (P < 0.05). Compared with the end of wash- out period, TC and LDL-C decreased in the treatment group at month 2 after second treatment (P < 0.05); TG, TC, and LDL-C decreased (P < 0.01, P < 0.05), and HDL-C increased (P < 0.05) at month 3 after second treatment. Compared with the control group at month 3 after second treatment, TG, TC, and LDL-C all decreased, and HDL-C increased in the treatment group (all P < 0.05).
CONCLUSIONBC was effective in improving blood lipid level in mild hyperlipidemia patients.

Objective To report filaminopathy with novel insertion mutation in a Chinese family.Methods Total 19 patients from successive 5 generations involved in an autosomal dominant family. The detailed clinical manifestations had been described (Chinese Journal of Neurology, 2008, 41:751-755).The filamin C gene sequencing was performed in 3 patients, 5 family members without symptoms and 50 normal persons. The amplified fragments of the exon 18 in filamin C gene were cloned into pBluesripts vectors, then sequenced and identified with capillary electrophoresis. Results 18-nucleotide deletion and 6-nucleotide insertion were identified in the exon 18 of filamin C gene. The mutation caused the disturbance of the seventh immunoglobulin-like domain in filamin C, leading to the instability of dimmers of filamin C.Another 2 patients in the family had same mutation while 5 family members without symptoms and 50 normal controls were normal. Conclusion The novel nucleotide deletion-insertion in exon 18 of filamin C gene causes filaminopathy. This disease can appear in non-Nordic race.

Lactic acid production of twelve strains of LAB isolated from broiler intestine and tolerance property of three strains were investigated. The results of lactic acid production showed that among all strains K6 exhibited the most rapid production during the first twelve hours, the seconds were K9 and C1; D17 exhibited the highest production of lactic acid by twenty-four hours, C1 exhibited the highest production of lactic acid by forty-eight hours. The pH values in three strains of K9、D17 and C1 culture showed the fast decline during the first twelve hours, with the final values significantly lower than those of other strains cultures. The results of tolerance property showed that the survival counts of C1could be detected when pH value was at 2 after three hours, but the survival counts of D17 and K9 could not be detected after one hour. When pH value was at 2.5 after three hours ,the survival counts of C1 declined from 10~ 8.2 /mL to 10~ 4.8 /mL, K9 from 10~ 8.2 /mL to 10~ 4.6 /mL, the survival counts of D17 could not be detected. 0.08% bile had few effects on the survival counts of three strains; when incubated in the medium with 0.40% bile, the survival counts of C1 declined from 10~ 8.4 /mL to 10~ 6.5 /mL,D17 from 10~ 10.3 /mL to 10~ 7.5 /mL, and K9 from 10~ 9.8 /mL to 10~ 7.7 /mL. When the group treated with 37℃ for 20 minutes was served as the control, the survival counts of C1 and K9 was not detected when treated with 80℃, but the survival counts of D17 were 10~ 4.9 /mL, when treatment with 65℃ the survival counts of C1 and K9 decreased significantly .

Objective To report 2 cases of Fabry disease with early-onset ischemic stroke and investigate the clinical and image features. Methods The 2 patients developed dizziness, diplopia and progressive memory decline at 32 and 25 years of age respectively. The α-galactosidase A (GLA)activity was 4. 3 U in case 1 and 1. 0 U in case 2 ( normal range 100-500 U). Skin biopsy showed numerous membrane bounded osmiophilic laminar material in vascular smooth muscle cells and endothelial cells. GLA gene analysis revealed GLA exon 7 1033-1034 TC del in case 1 and GLA exon 3 466G > A in case 2. The 2 patients were evaluated by Mainz severity score index (MSSI) and cranial MRI. Results The general MSSI was 32 in case 1 and 16 in case 2, with the highest score of neurological score ( 11 and 14). Both cases showed multifocal infarcts in bilateral cerebellum, occipital lobe, basal ganglia, which were hypointensity on T1 WI and hyperintensity on T2WI. There were hyperintensity changes in the pulvinar and basal ganglia on T1 WI in case 2. Conclusions Cerebral ischemic stroke could appear as initial symptoms in Fabry disease,which predominantly involved the posterior circulation. There might be no dilation of basal-vertebral artery.

OBJECTIVETo observe the characteristics of sperm single-stranded DNA breaks (SSB) and double-stranded DNA breaks (DSB) in infertile men, explore the association of DSB with male infertility, and provide a new observation index and idea for the diagnosis and treatment of the disease.
METHODSThis study involved 60 infertile men (infertility group) and 30 normal healthy males with infertile wives (control group). We comparatively analyzed the seminal parameters of the two groups, determined sperm concentration and viability using the computer aided sperm analysis system, measured the sperm survival rate by hypoosmotic swelling (HOS) test, examined sperm morphology by Diff-Quick staining, and detected sperm DNA damage by two-tail comet assay.
RESULTSNine two-tail comet models were established for detecting sperm DNA integrity. Comparisons between the fertility and control groups showed that the sperm DNA fragmentation index (DFI) was (33.8 ± 13.1) vs (16.3 ± 7.9)% (P < 0.01), the SSB-DFI was (19.2 ± 11.4) vs (14.9 ± 7.6)% (P > 0.05), the SSB-DFI/DFI was (56.8 ± 32.4) vs (91.4 ± 27.8)% (P < 0.01), the DSB-DFI was (23.9 +13.4) vs (6.1 ± 2.7)% (P < 0.01), and the DSB-DFI/DFI was (70.8 ± 19.5) vs (37.4 ± 11.3)% (P < 0.01). The optimal cut-off value of DSB-DFI/DFI in the diagnosis of male infertility was 39.5%, with the AUG, sensitivity, and specificity of 0.969, 98.3%, and 90%; that of DSB-DFI was 15.85%, with the AUC, sensitivity, and specificity of 0.912, 86.7%, and 80%; and that of DFI was 18.65%; with the AUC, sensitivity, and specificity of 0.861, 90%, 70%, respectively. In the infertile men, neither SSB-DFI nor SSB-DFI/DFI exhibited any correlation with semen parameters (P > 0.05); DFI was correlated negatively with the percentage of progressively motile sperm, sperm survival rate, and the percentage of morphologically normal sperm (P < 0.05 or P < 0.01), but not correlated with sperm concentration (P > 0.05); both DSB-DFI and DSB-DFI/DFI showed a negative correlation with sperm concentration, sperm survival rate, and the percentages of progressively motile sperm and morphologically normal sperm (P < 0.05 or P < 0.01).
CONCLUSIONDouble-stranded, rather than single-stranded DNA breaks, may be a factor inducing male infertility. The type of sperm DNA strand damage is of much reference value for the assessment of male fertility.
