Background Leber hereditary optic neuropathy (LHON) is a disease characterized by maternal inheritance.A number of mitochondrial DNA (mtDNA) mutation has been thought to be associated with this disease.Objective This study was to investigate the clinical and molecular genetic properties of LHON in two Chinese families.Methods Forty subjects from two Chinese families with LHON were enrolled in Affiliated First Hospital of Zhengzhou University,including 28 maternal members (10 of these members are LHON and 12 controls from two families.All the participants had a complete ophthalmic examination including visual acuity,direct ophthalmoscopy,color sensation and visual evoked potentials.MtDNA was extract from the whole blood sample of all participants.PCR-DNA sequencing was performed to detect the point mutation of the G11778A,T14484C,and G3462A for each subject.Written informed consent was obtained from each subject prior to this study.Results Only G11778A point mutation was identified in all 28 maternal members from the two families.No point mutation of G11778A was identified in non-maternal members,and no point mutation of the T14484C and G3462A were found in the two families.Conclusions The inherited pattern of these two families shows typical clinical and genetic features of LHON.LHON patients with G1 1778A mutation have a poor prognosis of visual acuity.

This study was aimed to evaluate the efficacy and safety of acupuncture treatment for diabetic peripheral neuropathy.MEDLINE, EMBASE, China National Knowledge Infrastructure (CNKI), and Wanfang database were searched. The study endpoints included clinical total efficacy, peripheral nerve conduction velocity and adverse reactions. The Review Manager software 5.2 was used in the bias and risk assessment as well as efficacy. GRADE profiler software was used to evaluate quality of evidences. The results showed that there were 18 randomized controlled trials (RCTs) with 1158 patients included. The clinical total efficacy rate of acupuncture treatment was obviously better than the drug control group [RR: 1.38, 95%CI (1.25, 1.53),P < 0.000 01]. The sensory nerve conduction velocity was that for nervus medianus, the acupuncture treatment group was superior to the drug control group [MD = 2.55, 95%CI (1.23, 3.87),P = 0.000 1]; for nervus peroneus communis, the acupuncture treatment group was superior to the drug control group [MD = 3.42, 95%CI (2.56, 4.28),P < 0.000 01]. The motor nerve conduction velocity was that for nervus medianus, the acupuncture treatment group was superior to the drug control group [MD= 4.10, 95%CI (1.01, 7.19),P = 0.009); for the nervus peroneus, the acupuncture treatment group was superior tothe drug control group [MD = 3.09, 95%CI (1.99, 4.19),P < 0.000 01]. The adverse reactions and safety indicators were that no adverse reaction was reported in both studies with no abnormal safety indicator. The quality of evidence showed that the sensory nerve conduction velocity for nervus peroneus communis was moderate; the motor nerve conduction velocities for nervus medianus and nervus peroneus communis were low. While, the clinical efficacy rate and the quality of evidence for sensory nerve conduction velocity of nervus medianus were relatively low. It was concluded that the current clinical evidences were uncertain for the efficacy and safety of acupuncture in diabetic peripheral neuropathy treatment.

To explore the significance of the application of standardized special staining technique in pathologic diagnosis of pulmonary fungal infectious diseases.Methods Final pathologic diagnosis of 104 cases pulmonary fungus infection disease in Beijing Chaoyang hospital from September 2011 to March 2016 were selected;HE staining only,HE staining combined with the traditional manual special staining method PAS and hexamine silver,and HE staining combined with automatic special staining PAS and hexamine-silver were used and compared.The two kinds of special staining technology were compared;the microscopic observation,analysis results (all the first staining results,not including the results of complex staining),the results on the basis of final pathologic diagnosis were also compared with the clinical preliminary diagnosis.Results Lung fungal infectious disease diagnosis rate and fungal classification rate,from low to high order consistence,showed that for the primary clinical diagnosis (29.8％ and 19.2％),HE staining (32.7％ and 32.7％),HE staining combined with traditional manual special staining method PAS and hexamine silver (90.4％ and 87.5％),and HE staining combined with automatic special staining PAS and hexamine-silver (98.1％ and 94.2％).The four methods were statistically significant on two aspects (P ＜ 0.01,P ＜ 0.01);the fourth method was significantly different from the first two (P ＜ 0.01,P ＜ 0.01).The fourth method was significantly different from the third kind of diagnosis rate (P ＜ 0.05),typing rate was no significant difference (P ＞ 0.05).But automatic special dyeing method of PAS and hexamine silver steps were more simple,with standardized chemical reagents,no artificial and environmental factors,short time-consuming,and less number of dropping-off and restaining of the section.Conclusion HE staining and its combination with automatic special staining of PAS and hexamine silver are much more standardized,and help to improve the diagnosis of pulmonary fungal infectious diseases and fungal classification rate.

Objective To observe the levels of matrix metalloproteinases-9 (MMP-9) and tissue factor (TF) as well as blood lipid in patients with acute coronary syndrome (ACS) ,and to study the effect of Fluvastatin on levels of serum MMP- 9 and plasma TF. Methods 40 patients with ACS were selected (including 20 patients with AMI and 20 patients with UAP) ,20 stable angina patients (SAP) and 13 patients without coronary heart dis-ease as control group. 40 patients with ACS were randomly assigned to the Fluvastatin group (n = 20) and the rou-tine group (n = 20) in this study. The MMP - 9 and TF were detected on admission and after 2 weeks treatment. Re-suits The levels of MMP-9 and TF were significantly higher in ACS group than that of SAP and control group (P < 0.001 ,P < 0.05) ,which were elevated in AMI group compared with that of UAP group (P < 0.05). The levels of cholesterol (TC) ,low density Lipoprotein (LDL - C) ,MMP- 9,TF decreased significantly at two weeks after treat-ment in fluvastatin group (P < 0.05), but no significant changes were observed in the routine group (P > 0.05). The change of MMP 9, TF and blood lipid was not related in fluvastatin group (P > 0.05). Conclusion Serum MMP-9 and plasma TF in ACS patients are significantly elevated and fluvastatin decreases the levels of MMP-9 and TF after two weeks treatment,so it may be benefit to atheroaclerotic plaque stabilization and prohihit thrombosis for-marion, and this is not related to regulation of blood lipid.

Objective:To compare the antihypertensive effects of tuina at Taichong (LR 3),Neiguan (PC 6) and Qiaogong (Extra) to screen the best tuina protocol for primary hypertension due to liver-fire flaming-up.Methods:A total of 102 patients with primary hypertension due to liver-fire flaming-up were randomly divided into a Taichong (LR 3) group,a Neiguan (PC 6) group and a Qiaogong (Extra) group according to the random number table,with 34 cases in each group.Patients in the three groups received 4-week tuina treatment with the corresponding acupoint respectively.The blood pressure was recorded by benchtop mercury sphygmomanometer before tuina,immediately after tuina treatment,30 min and 60 min after tuina treatment with the patient in a supine position in a quiet treatment room.The total effective rate was observed.Results:The systolic and diastolic blood pressures of the three groups all decreased after treatment (all P＜0.05).The decrease of systolic and diastolic blood pressure at different time points after treatment in the Qiaogong (Extra) group and the Taichong (LR 3) group were better than those in the Neiguan (PC 6) group (all P＜0.05).Qiaogong (Extra) group had the highest total effective rate though there was no statistical difference in the total effective rate among the three groups (P＞0.05).Conclusion:Treating primary hypertension due to liver-fire flaming-up with tuina at Taichong (LR 3),Neiguan (PC 6) and Qiaogong (Extra) can reduce systolic and diastolic blood pressure respectively,among which Qiaogong (Extra) has the highest total effective rate.

Insulin resistance and insulin secretion deficiency are main machanisms in inducing type 2 diabetes mellitus (T2DM), and mitochondria damage plays an important role in them. Research shows that autophagy is a self-protective mechanism of cells, which plays an important role in maintaining the normal structure and function of pancreatic β cells and improving insulin resistance. Previous studies show that traditional Chinese medicine can regulate cell autophagy to influence β cells and insulin resistance, type 2 diabetes mellitus and its complications. Thus this review will talk about the process of the relationship between autophagy and T2DM and the intervention effect of traditional Chinese medicine.
