AIM: To study the effectiveness of hyaluronidase periocular injection combined with α - lipoic acid and Chinese medicine in the treatment of diabetic vitreous hemorrhage.
METHODS: Retrospective analysis of 67 patientswith proliferative diabetic retinophathy ( PDR ) and vitreous hemorrhage, were divided into two groups: treatment group and control group. There were 32 cases in every group, the treatment group were giving hyaluronidase periocular injection combined with α - lipoic acid intravenously and with traditional Chinese medicine in promoting blood circulation to remove blood stasis, control group were only given Chinese medicine treatment in promoting blood circulation to remove blood stasis.
RESULTS: Followed up 2-3mo, the total efficiency of treatment group ( 78%) was better than control group (57%), there was statistically significant difference ( P<0-05 ) . The efficiency of the two groups' patients with vitreous hemorrhage more than 2wk time was 22% and 25% respectively, there was no statistically significant difference in the two groups (P>0. 05).
CONCLUSION: Hyaluronidase periocular injection combined with α-lipoic acid and Chinese medicine in the treatment of PDR combined with vitreous hemorrhageis more effective than only use Chinese medicine. But it only has effect for the early, over 2wk, it has no significant effect.

Objective To exPlore the effect of mammalian target of raPamycin ( mTOR ) inhibitor eVerolimus on radiosensitiVity of human non_small cell lung cancer cell line in vitro by using eVerolimus to inhibit mTOR signaling Pathway of A549. Methods Human non_small cell lung cancer cell line A549 was subjected to radiation alone or in combination with eVerolimus treatment. The 50%inhibition concentration ( IC50 ) of eVerolimus in A549 cells was detected by methylthiazol tetrazolium ( MTT) assay in vitro. EVerolimus at the 20%inhibition concentration ( IC20 ) was used to Pretreat A549 cells for 24 h. Cells were then irradiated by X_ray with 2,4,6,8 Gy. The cell surViVal fraction was comPuted by clone formation. Cell surViVal curVe was fitted by multitarget one_hit model, and mean lethal dose ( D0 ), dose quasithreshold ( Dq ), surViVal fraction at 2 Gy ( SF2 ), and sensitization enhancement ratio (SER) were calculated. The exPression ofγ_H2AX was determined by Western blotting and then the relatiVe gray Values were analyzed. Results EVerolimus significantly imProVed the sensitiVity of A549 cells to radiation. The D0 , Dq and SF2 of eVerolimus+irradiation grouP were significantly lower than those of irradiation grouP. The SER was 1. 36. The residual amount of γ_H2AX Protein in the eVerolimus + irradiation grouP was significantly higher than that of the irradiation grouP. Conclusion EVerolimus inhibiting mTOR signaling Pathway can increase the radiosensitiVity of A549 cells.

Objective To explore the clinical characteristics and the cause of misdiagnosis of child suffering from cerebral parago-nimiasis with intracranial hemorrhage as initial symptom,and to improve the diagnosis and treatment level of cerebral paragonimiasis.Methods The clinical data of the children who suffered from cerebral paragonimiasis with intracranial hemorrhage as initial symptom were collected from January 2011 to December 2015 in Affiliated Hospital of Zunyi Medical College.The clinical manifestation,imageology and laboratory tests,outcome of therapy were analyzed and then the effect of treatment and the prognosis were followed up.Results There were 7 patients meeting the inclusion criteria for cerebral paragonimiasis,including 4 male and 3 female.They were from 6 to 13 years old with the average age of 9.3 years old.All patients presented with headache and vomiting,and showed intracranial hemorrhage through CT or MRI of brain.All of the 7 patients were misdiagnosed as cerebrovascular malformation by the neurosurgeons.Three of them showed typical imaging pattern including tunnel sign and the ring-like shape of cerebral paragonimiasis.Five of these cases were attacked by pulmonary distomiasis at the same time.Six of them had an increasing eosinophil,and the paragonimus antibody was positive.They were treated with Praziquantel.Six patients recovered completely,and 1 patient had the dysfunction of left extremities.Conclusions The childhood cerebral paragonimiasis has strong clinical heterogeneity and diversity in manifestation.Intracranial hemorrhage may be the initial symptom,which should be paid more attention to.Cerebral paragonimiasis can be diagnosed and treated early according to the clinical characteristics,the increase of eosinophil,the typical changes in imageology and the specific antibody test.

With the development of various laboratory testing techniques such as serum calcium and parathyroid hormone (PTH) , a large number of asymptomatic or normocalcemic primary hyperparathyroidism (PHPT) can be diagnosed early. PHPT has become the third most common endocrine disease affecting human health. Currently, most PHPT, especially normocalcemic primary hyperparathyroidism, are not primary diseases and may be related to vitamin D deficiency/insufficiency and/or insufficient calcium supplementation. That is, the relative hypocalcemia caused by long-term vitamin D deficiency/insufficiency and/or insufficient calcium supplementation leads to parathyroid hyperfunction, stimulates parathyroid hyperplasia, and secretes excessive parathyroid hormone to compensate for the regulation of calcium and phosphorus balance. When it is in the initial reversible stage, it can be cured by internal medicine; if it progresses freely, long-term hypocalcemia stimulation will lead to excessive parathyroid hyperplasia and even tumor occurrence with the formation of so-called PHPT and parathyroidectomy has to be performed. Therefore, routine screening of bone mineral density, calcium, magnesium, phosphours, 25-hydroxyvitamin D, parathyroid hormone and other bone metabolism indicators in the physical examination of general population is beneficial to the prevention and treatment of bone metabolism diseases, urinary stones and hyperparathyroidism. At the same time, attention should be paid to identifying the stage of prehyperparathyroidism in which vitamin D deficiency/insufficiency and insufficient calcium supplementation will stimulate parathyroid hyperfunction. Active intervention on prehyperparathyroidism is an effective way to avoid the development of primary hyperparathyroidism.

Childhood polyarteritis nodosa (PAN) is a rare systemic vasculitis and the delayed diagnosis and treatment will cause high incidence of sequelae and high mortality. This article reports a girl with childhood PAN due to posterior reversible encephalopathy syndrome (PRES). The girl aged ten years was admitted to the hospital due to hypertension and convulsions for one month. She had complaints of headache, vomiting, and blurred vision before convulsions. At six months before admission, a mass was observed in the neck. The physical examination showed that she had hypertension and no abnormal findings in the central nervous system. The brain magnetic resonance imaging manifested long T1 and T2 signals, high signal intensities on fluid-attenuated inversion recovery (FLAIR) images, and iso-signal intensity on diffusion-weighted imaging in the white matter of the left occipital lobe. Therefore, the cause of convulsions was considered as PRES. Mass biopsy suggested PAN and no findings supported tuberculosis. The right kidney atrophy was observed by ultrasound examination. Emission computed tomography of the kidney showed multiple vascular stenosis and no blood perfusion in the right kidney, so PAN was confirmed. These findings suggest that PAN should be considered in patients with vasculitis who had involvements of multiple systems after excluding common vasculitis, such as Kawasaki disease and Henoch-Schönlein purpura. Biopsy and angiography should be performed as early as possible for timely diagnosis and treatment.

OBJECTIVETo observe the effect of calorie restriction on the high fat diet rats mRNA expressions of liver forkhead box O1(FoxO1), phosphoenolpyruvate carboxykinase (PEPCK), glucose-6-phosphatase (G-6-P) and to explore the possible mechanisms.

METHODS24 normal 6-week-old male Wistar rats were randomly divided into three groups: normal chow group (NC, n = 7), high fat diet group (HF, n = 9) and calorie restriction group (CR, n = 8). They were fed for 12 weeks. At the end of the experiment, the rats were sacrificed and their fasting blood glucose (FBG), insulin (INS), triglycerides (TG), total cholesterol (TC) were measured. Their visceral fat (VF) and body weight (BW) were also measured and VF/BW was calculated. Gene expression was investigated by using semi-quantitative RT-PCR methods. Liver histology was studied with HE stained slides.

RESULTSCompared with the NC group, HF group rats developed visceral obesity which was accompanied by higher FBG, plasma INS, TG, and TC. The levels of FoxO1, PEPCK, and G-6-P increased by 18.9%, 33.8%, and 24.6%, respectively (P less than 0.01). Liver steatosis was observed with microscopy. The BW, VF FBG, INS, TG and TC of the CR group rats were lower in comparison to those of the HF group. The levels of FoxO1, PEPCK and G-6-P were lower by 26.6%, 35.0%, 34.3% (P less than 0.01). Meanwhile, liver steatosis was also milder.

CONCLUSIONCalorie restriction can inhibit the expressions of FoxO1, PEPCK and G-6-P, strengthen insulin signal conduction, suppress gluconeogenesis and thus regulate glycometabolism.

OBJECTIVETo observe different effects of moxibustion on extracellular potassium ion in acupoint under physiological and pathological status and provide experimental evidence for exploring action mechanism of moxibustion on acupoint local.

METHODSForty female SD rats were randomly divided into a blank group, a blank-moxibustion group, a model group and a model-moxibustion group, 10 cases in each one. The complete Freund's adjuvant(CFA) was adopted to establish model of adjuvant arthritis (AA) in the model group and model-moxibustion group. No treatment was given in the blank group and model group while moxibustion was applied at "Zusan-li" (ST 36) for 30 min in the blank-moxibustion group and model-moxibustion group. The tissue fluid in "Zusanli" (ST 36) was collected with microdialysis and real-time analyzed by electrolytic analyzer. The change of concentration of potassium ion in "Zusanli" (ST 36) was observed.

RESULTS(1) Under physiological status, the concentration of extracellular potassium ion in the blank group was not changed within 150 min (P > 0.05); before the moxibustion, the concentration of extracellular potassium ion in the blank-moxibustion group was (1.21 +/- 0.31) mmol/L, and after treatment it was gradually increased and reached its peak at (2.38 +/- 0.42) mmol/L after 60 min (P < 0.05), then it was reduced. 150 min after the treatment, concentration of potassium ion was slightly higher than that before moxibustion as well as that in the blank group. The concentration in the blank-moxibustion group at 60 min was statistically significant compared with that in the blank group (P < 0.05). (2) Under pathological status, the concentration of extracellular potassium ion in the model group was not changed within 150 min, differences of which at each time point was not statistically significant (all P > 0.05). Before the moxibustion, the concentration of extracellular potassium ion was (1.09 +/- 0.12) mmol/L in the model-moxibustion group, and it was immediately increased to (1.96 +/- 0.18) mmol/L after moxibustion. 60 min and 90 min after the moxibustion, it still maintained a higher level, which was (1.87 +/- 0.29) mmol/L and (1.59 +/- 0.16) mmol/L respectively (both P < 0.05). The differences of each time point after moxibustion in the model-moxibustion group were statistically significant compared with those in the model group (all P < 0.05).

CONCLUSIONThe moxibustion could increase the concentration of potassium ion in rat's acupoint local under physiological status but time of effect is short; with moxibustion at "Zusanli" (ST 36) under pathological status, the concentration of local potassium ion is obviously increased and maintains for a long time.

OBJECTIVETo compare the effect of the extracts from Decoction for resuscitation (DRE) and its component herbs on prostacyclin (PGI2), thromboxane A2 (TXA2) and nitric oxide (NO) release from rat vascular endothelial cells under hypoxia.

METHODAfter treatment with the extracts from DRE and its component herbs, the contents of 6-keto-prostaglandin F1alpha(6-keto-PGF1alpha), thromboxane B2 (TXB2) as well as nitrite (NO), which were degradation products of PGI2, TXA2 and NO respectively, in culture medium of rat vascular endothelial cells under hypoxia were measured with radioimmunoassay and Griess Reaction.

RESULTCompared with the control group, the results indicated that DRE, prepared licorice root extract (LE), dried ginger extract (GE), aconite root extract (AE), extracts of aconite root and prepared licorice root (ALE), extracts of aconite root and dried ginger (AGE) increased significantly the content of 6-keto-PGF1alpha and the ratio of 6-keto-PGF1alpha/TXB2, but had no effect on the content of TXB2 in culture medium of rat vascular endothelial cells under hypoxia. The content of 6-keto-PGF1alpha in the DRE group was higher than that in the groups of LE, GE, AE, ALE, AGE. The ratio of 6-keto-PGF1alpha/TXB2 in the DRE group was higher than that of the groups of GE, AE, ALE. Compared with the control group, DRE, LE, GE, AE, ALE, AGE increased significantly the content of NO2- in culture medium of rat vascular endothelial cells under hypoxia. Moreover, the content of NO2- in the DRE group was higher than that of the groups of GE, AE, ALE.

CONCLUSIONThe results suggested that DRE increased significantly the content of PGI2 and the ratio of PGI2/TXA2 as well as the content of NO. The effect of DRE on the parameters in culture medium of rat vascular endothelial cells under hypoxia was better than that of the extracts from its component herbs.
