Journal of Southern Medical University 2010;30(4):664-667
OBJECTIVETo study the functional and ultramicrostructural effects of alpha lipoic acid on hypothalamus-pituitary-adrenal (HPA) axis in normal and diabetic rats.
METHODSUsing radioimmunoassay we observed the effects of three doses (1, 20, and 100 mg/kg) of alpha lipoic acid injected intraperitoneally for 3 weeks on the plasma levels of CRH, ACTH and COR in normal and diabetic rats. The ultramicrostructural changes of the hypophysis and pituitary gland after alpha lipoic acid treatment were observed under transmission electron microscope.
RESULTSCompared with the control group, CRH level in lipoicin-treated normal and diabetic rats was significantly reduced (P<0.05). ACTH level of the 3 lipoicin doses groups of normal rats decreased, and a significant reduction occurred in medium-dose lipoicin group of diabetic rats (P<0.05). COR level showed the same changes as CRH level in normal rats, but decreased significantly in high- and medium-dose lipoicin groups of diabetic rats. Lipoicin treatment produced no apparent effect on the ultramicrostructures of the hypophysis and pituitary gland cells, which were the targets of diabetic lesions with low metabolism functions. Lipoicin treatment obviously enhanced the hypophysis and pituitary gland cell metabolism function to resist diabetic oxidative stress.
CONCLUSIONLipoicin can inhibit the HPA axis directly or indirectly in normal and diabetic rats.

A method for simultaneous determination of the shikonin, acetyl shikonin and β, β'-dimethylpropene shikonin in Onosma hookeri and the chromatographic fingerprint was estabished by HPLC-DAD on an Agilent Zorbax SB-column with a gradient elution of acetonitrile and water at 0.8 mL x min(-1), 30 degrees C. The quality assessment was conducted by comparing the content difference of three naphthoquinone constituents, in combination with chromatographic fingerprint analysis and systems cluster analysis among 7 batches of radix O. hookeri. The content of the three naphthoquinone constituents showed wide variations in 7 bathces. The similarity value of the fingerprints of sample 5, 6 and 7 was above 0.99, sample 2 and 3 above 0.97, sample 3 and 4 above 0.90, and other samples larger than 0.8, which was in concert with the content of three naphthoquinone constituents. The 7 samples were roughly divided into 4 categories. The results above indicated that the using of this medicine is complex and rather spotty. The established HPLC fingerprints and the quantitative analysis method can be used efficiently for quality assessment of O. hookeri.

Objective This study aimed to explore clinical characteristics of four types of obesity based on metabolic classification. Methods Forty-eight obese patients were divided according to their clinical characteristics into 4 groups including metabolic healthy obesity (MHO), hypometabolic obesity (LMO), hypermetabolic obesity (HMO), and metabolic obesity with inflammation (IMO). 20 normal weight individuals were also recruited as a control group. Body fat, body weight, visceral index, and basal metabolism were measured by Omron body fat meter. Fat content and its distribution were measured by dual energy X-ray absorptiometry. All participating patients underwent various tests for 75 g oral glucose tolerance, blood glucose, insulin, C peptide. Lipid profile, thyroid function and sex hormones levels, and inflammation factors were also measured. Results (1)Patients in MHO group had higher body fat content, but had no metabolic disorder and inflammation. Their hormones levels were normal. (2) Lower metabolic rate and lower hormones levels were found in the patients in LMO group with increasing visceral fat. Trunk/subcutaneous fat mass was significantly higher than that in MHO group(1. 19 ± 0. 25 vs 0. 97 ± 0. 32, P<0. 05). There were abnormal lipid and glucose metabolism in LMO group. The insulin action index was significantly lower than that in MHO group(0. 006 6 ± 0. 002 7 vs 0. 012 1 ± 0. 009 5, P<0. 05). The area under the curve of glucoseconcentrationwassignificantlyhigherinLMOgroupthanthatinMHOgroup[(18.71±8.68vs12.70±4.63) mmol/L, P<0. 05]. (3)Heart rate and blood pressure were higher in HMO group. The heart rate was significantly increased compared with that in MHO group [(90. 50 ± 8. 24 vs 73. 20 ± 14. 11) beat/min, P<0. 05]. The waist circumference was significantly larger than that in MHO group [(111. 88 ± 10. 54 vs 98. 05 ± 15. 56) cm, P<0. 05]. (4) In IMO group, insulin action index was significantly lower than MHO group (0. 007 0 ± 0. 003 3 vs 0.0121±0.0095,P<0.05). ThetrunkfatmassanduricacidlevelsweresignificantlyhigherthanMHOgroup [(17236.38±4610.60vs15816.10±5453.42)gand(468.28±121.32vs376.84±97.14) μmol/L,bothP<0. 05]. Patients in IMO group had acanthosis nigricans, but their glucose level was relatively normal. Conclusion The metabolic-based obese diagnosis is essential for understanding the obesity etiology and providing individualized treatment.

OBJECTIVETo search for the best therapy for simple obesity.
METHODSEighty cases were randomly divided into 3 groups. The body acupuncture group were treated based on the syndrome of heat of stomach and intestine, syndrome of spleen deficiency and stagnation of dampness, and syndrome of spleen and kidney yang-deficiency; the auricular and body acupuncture group were treated by the syndrome treatment of body acupuncture combined with auricular point sticking; the observation group were treated by the combined auricular and body acupuncture treatment plus moving cupping on back-shu points. Body weight, BMI, body fatd, blood lipids and clinically main symptoms before and after treatment were investigated.
RESULTSThe total effective rate was 69.6% in the body acupuncture group, 76.0%. in the auricular and body acupuncture group, and 90.6% treated in the observation group, with significant differences in the therapeutic effect, clinically main symptoms, external indexes of obesity and kidney ang-blood lipid metabolism between the observation group and the body acupuncture group. The various indexes in the auricular and body acupuncture group were superior to those iwere tthe body acupuncture group, with no significant differences in most indexes.
CONCLUSIONAuricular and body acupuncture combined with moving cupping at back-shu points has obvious therapeutic effect on simple obesity and this is a better therapy for simple obesity.

OBJECTIVETo investigate the change of zygomatic and temporal soft tissue after coronal incision.
METHODSA retrospective analysis was performed in 33 patients who received firm fixation for unilateral zygomatic comminuted fracture through semi-coronal incision. All the patients were followed up for more than one year. Craniofacial anthropometric measurement through 3D-CT reconstruction and facial profile was performed. The difference between the operated side and healthy side was analyzed.
RESULTSAt the temporal concave point, the soft tissue thickness at healthy side was (1.60 +/- 0. 97) mm more than that at operated side, showing a significant difference between them (P < 0.01). While the soft tissue thickness was not statistically different between two sides at zygion, malar prominence, zygomaxillare, and temporal convex point (P > 0.05).
CONCLUSIONSThe soft tissue atrophy may happen at temporal fat pad after semi-coronal incision, but not at zygomatic area. Intraoperative precise dissection and less stretch of soft tissue may be helpful to avoid the postoperative facial asymmetry.

8.Analysis of factors related to reuse behavior of insulin pen needles under Shanghai new medical insurance policy
Chinese Journal of General Practitioners 2020;19(5):447-450
One hundred and ninety-three type 2 diabetic patients of average age of 70.3 years (96 males and 97 females), receiving insulin treatment at Diabetes Clinic of Caoyang Subdistrict Community Health Service Center from April to October 2018 were enrolled in the study. During the first visit, the average times of insulin injection pen needle use in the past month and the reason for repeated use were investigated; and the patients were informed that under the medical insurance policy in Shanghai, the reimbursement rate of the needles was increased to 80%. The patients were regularly instructed on the use of insulin needles in the follow-up visits. After 5 months the times of each insulin needle use were surveyed again. The first survey showed that 97.5% (188/193) of patients reused insulin needles, and each needle was used for (11.8±9.8) times; while the second survey showed that each needle was used for (4.4±4.4) times. Binary logistic regression analysis showed that the reuse behavior was affected by the frequency of education given by medical staff and the patient′s perception on expensiveness of the needles. It is suggested that clinical health education and fully informing medical insurance policy is important for the behavior change of reusing insulin injection pen needles in diabetic patients.

OBJECTIVETo map the candidate gene by linkage analysis in a Chinese family with autosomal dominant congenital retinaochoroidal coloboma.
METHODSA detailed clinical examination was performed for all patients in the family. The genomic DNA of all family members was extracted from peripheral blood leukocytes. Linkage analysis and genome-wide linkage screening was conducted using fluorescent detection of 398 microsatellite markers representing all autosomes at an average resolution of approximately 10 cM. Polymerase chain reaction was carried out to amplify all 398 microsatellite markers. The allele sizes were determined on ABI 3130-Avant genetic analyzer according to an internal size standard, and the results were analyzed using Genescan 3.1 and Genotyper 2.0 software.
RESULTSLinkage analysis showed the markers D2S2382-D2S301-D2S2244-D2S163 co-segregated with the disease locus in all affected members. The maximum Lod score was 3.01(D2S2382).
CONCLUSIONThe candidate region of the disease gene in the family was located in 2q34-2q35.

In addition to providing energy for cells, mitochondria also participate in calcium homeostasis, cell information transfer, cell apoptosis, cell growth and differentiation. Therefore, maintaining mitochondrial homeostasis is very crucial for the body to carry out normal life activities. Ubiquitination, a post-translational modification of proteins, is involved in various physiological and pathological processes of cells by regulating mitochondrial homeostasis. However, the mechanism by which ubiquitination regulates mitochondrial homeostasis has not been summarized, especially the effect of Parkin protein on cardiovascular diseases. In this paper, the specific mechanism of mitochondrial homeostasis regulated by ubiquitination of Parkin protein is discussed, and the influence of mitochondrial homeostasis imbalance on cardiovascular diseases is reviewed, with a view to providing potential therapeutic strategies for the clinical treatment of cardiovascular diseases.
