Objective:To observe the clinical effect of warm needling moxibustion plus Kai Qing Long Suo tuina therapy (opening the Qing Long lock,one type of'Eight and a Half Locks' tuina therapy) for cervical spondylosis of vertebral artery type (CSA).Methods:Sixty patients with CSA were randomly allocated into an observation group or a control group,with 30 cases in each group.The observation group was treated with warm needling moxibustion plus Kai Qing Long Suo tuina therapy,while the control group was treated with warm needling moxibustion alone.Warm needling moxibustion was conducted once every other day and tuina was conducted once a day,7-day treatments for one course.The clinical efficacy and vertebral artery blood flow was observed after one course of treatment.Results:After treatment,the total effective rate was 93.3％ in the observation group versus 80.0％ in the control group,and there was a significant difference between the two groups (P＜0.05).After treatment,the systolic blood flow velocity of vertebral artery increased in both groups,with statistical significance compared with that before treatment (both P＜0.05),and the blood flow velocity in the observation group was faster than that in the control group,with statistical significance between the two groups (P＜0.05).Conclusion:Both warm needling moxibustion plus Kai Qing Long Suo tuina therapy and warm needling moxibustion alone are both effective for CSA,can improve the systolic blood flow velocity of vertebral artery.The curative effect of warm needling moxibusiton plus Kai Qing Long Suo tuina therapy is better than that of warm needling moxibustion alone.

Sangzhi alkaloids (SZ-A) are derived from traditional Chinese medicine Ramulus Mori, serving well as an innovative antidiabetic drug, due to α-glucosidase inhibition. To evaluate the potency of glucosidase inhibitory effect of SZ-A, the enzyme-based screening platforms, including sucrase, maltase and amylase were established, and IC₅₀ was calculated. The effects of SZ-A on postprandial blood glucose at a single dose, oral sucrose, starch and glucose loading were determined in normal ICR mice and alloxan-induced hyperglycemic mice. To confirm the anti-diabetic effects of SZ-A on glucose and lipid metabolism after long-term administration, the postprandial and fasting blood glucose, serum insulin, urinary glucose levels, glycosylated serum proteins and blood lipid levels were determined in high-fat fed C57 obese mice (pre-diabetic HFC57 mice) and diabetic rats induced by streptozotocin (STZ). The Experimental Animal Welfare Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College approved all of the protocols for this research. We found that SZ-A exhibited a significant inhibitory effect on the sucrase and maltase. SZ-A showed no effect on amylase. In normal ICR mice and alloxan-induced hyperglycemic mice, SZ-A at a single dose significantly delayed and reduced the peak of blood glucose after sucrose or starch loading, but showed no effect on the increase of blood glucose after glucose loading. In STZ diabetic rats, SZ-A significantly reduced the postprandial or fasting blood glucose levels, glycosylated serum proteins and urinary glucose. SZ-A also reduced serum triglyceride (TG) and cholesterol (TC) levels after 3 weeks of treatment. SZ-A ameliorated the postprandial blood glucose or the fasting blood glucose elevation, and reduced the incidence of hyperglycemia in HFC57 mice. SZ-A decreased the basal insulin level, improved insulin sensitivity, and ameliorated glucose intolerance in pre-diabetic HFC57 mice. Our results indicated that SZ-A had a novel inhibitory activity on α-glucosidase, especially on disaccharidases. SZ-A at a single dose significantly reduced the peak of blood glucose elevation and delayed the increase of blood glucose in normal and diabetic mice after disaccharide and polysaccharide loading. Long-term SZ-A treatment improved glucose and lipid metabolic profiles by delaying carbohydrate absorption from the intestine and reduced the postprandial blood glucose levels in both pre-diabetic and diabetic animal models. Therefore, SZ-A application may display a beneficial role in preventing the development and complications of diabetes.

BACKGROUND:Bushen Huoxue Decoction(BSHXD)can promote osteogenesis of bone marrow mesenchymal stem cells(BMSCs)in vitro.Exploring the molecular mechanisms involved is of clinical benefits. OBJECTIVE: To discuss the changes in the expression of SP7/Osterix and alkaline phosphatase (ALP) in BMSCs with Cbfal/RUNX2 gene silencing regulated by the water extracts from BSHXD. METHODS: BMSCs were isolated and cultured by the bone marrow adherent method, and BMSCs at passage 3 were used in the assay. BMSCs were transfected with nothing (blank control group), Cbfal/RUNX2 gene silencing lentivirus (silencing group), and negative viral vector (negative control group), respectively. Then, the cells were cultured in 100 mg/L BSHXD water extract, and 3 days later, the protein and mRNA expression of RUNX2 and Osterix was detected by western blot and qPCR, respectively. Activity of ALP in the BMSCs was also detected in each group. RESULTS AND CONCLUSION: The transfection efficiency of Cbfal/RUNX2 gene silencing lentivirus was about 90%. The protein and mRNA expressions of RUNX2 and Osterix were significantly decreased in the BMSCs transfected with Cbfal/RUNX2 gene silencing lentivirus as compared with the other two groups, and so was the ALP activity (P < 0.01). After treated with the water extracts from BSHXD, the expression of RUNX2 and Osterix as well as the ALP activity in the BMSCs transfected with Cbfal/RUNX2 gene silencing lentivirus increased significantly (P < 0.01). To conclude, the water extract from the BXHXD can up-regulate the expression of RUNX2 and Osterix and the activity of ALP, thus promoting BMSCs osteogenic differentiation.

Objective To investigate the impact of fasting blood glucose on the prognosis of non-diabetic patients undergoing primary percutaneous coronary intervention (PCI) for acute ST-segment elevation myocardial infarction (STEMI). Methods We retrospectively recruited consecutive patients who underwent primary PCI in our hospital from February, 2003 to March, 2015. Patients with prior history of diabetes mellitus before the index hospitalization and those with newly diagnosed diabetes mellitus during the index hospitalization were excluded. The clinical and angiographic features, medical and interventional treatment, and 30-day outcomes were compared between patients with elevated fasting blood glucose (FBG) (>5.4 mmol/L) and those with normal FBG (≤5.4 mmol/L). Results A total of 721 patients were recruited with an age of(61.2 ± 12.8)years, of whom 601 (83.4 %) were male. As compared with patients with normal FBG,those with elevated FBG were more likely to be female(20.1 % vs.13.5 %, P=0.017),had faster heart rate on admission[(82.9 ± 17.2)bpm vs.(79.4 ± 16.7)bpm,P=0.006]and more use of intra-aortic balloon pump(3.8 % vs.1.3 %,P=0.034),and had higher rates of 30 day all-cause mortality(3.5 % vs.0.5 %,P=0.004),cardiac mortality(2.9 % vs.0.5 %,P=0.012)and heart failure(18.1 % vs. 7.4 %, P< 0.001). After adjusting baseline characteristics, FBG > 5.4 mmol/L was one of the independent predictors of 30-day all-cause mortality(HR 6.030,95 % CI 1.235-29.447,P=0.026).Other independent predictors of 30-day all-cause mortality included age(HR 1.059,95 % CI 1.002-1.120,P=0.044),heart rate on admission(HR 1.036,95 % CI 1.003-1.070,P=0.034),left descending artery as the culprit vessel(HR 6.427,95 % CI 1.389-29.728,P=0.017),and use of angiotensin converting enzyme inhibitor/angiotensin receptor blocker(HR 0.154,95 % CI 0.051-0.461,P=0.001).Conclusions In non-diabetic patients undergoing primary PCI for STEMI, elevated FBG was one of the independent predictors of 30-day all-cause mortality.

Objective:To observe the clinical efficacy of Yi Jin Jing (Sinew-transforming Qigong Exercises) for primary osteoporosis in the elderly.Methods:Eighty old patients with primary osteoporosis were randomized into a Yi Jin Jing group and a medication group,40 cases in each group.The Yi Jin Jing group was intervened by Yi Jin Jing (Sinew-transforming Qigong Exercises) training,while the medication group was intervened by oral administration of alendronate sodium tablet.Prior to and after 6-month intervention,the bone mineral density (BMD) of the proximal femur,visual analog scale (VAS) and activities of daily living (ADL) were estimated.Results:There were no significant differences in the BMD of the proximal femur,and VAS and ADL scores between the two groups before the intervention (P＞0.05).After 6-month intervention,the above items all improved significantly in both groups (both P＜0.01);the improvements in VAS and ADL scores in Yi Jin Jing group were more significant than those in the medication group (P＜0.01),while the between-group difference in the BMD of the proximal femur was statistically insignificant (P＞0.05).Conclusion:Practice of Yi Jin Jing (Sinew-transforming Qigong Exercises) can effectively ameliorate the BMD in the elderly with primary osteoporosis,and it can reduce the pain and improve ADL,with a better general effect compared to oral administration of alendronate sodium tablet.

OBJECTIVETo analyze the relationship between orbital fat volume and the progression and prognosis of thyroid- associated ophthalmopathy (TAO) and determine the optimal treatment timing for TAO.

METHODSThe clinical data were collected from 35 patients (70 orbits) with a definite diagnosis of TAO between January, 2016 and December, 2016. The correlation between orbital fat volume and the clinical parameters was evaluated. We also analyzed the correlation of the signal intensity ratio (SIR) of the extraocular muscles with the clinical parameters. The orbital fat volume was compared between patients with TAO and 12 control subjects.

RESULTSThe orbital fat volume was significantly correlated with the duration of TAO (r=0.480, P<0.01), but showed no significant difference between patients with a disease course within 6 months and those with a disease course of 6 to 12 months (P=0.084). The patients with a disease course beyond 12 months had a significantly greater orbital fat volume than those with a disease course of 6 months (P<0.01) or 6 to 12 months (P<0.05). The orbital fat volume was correlated with the degree of proptosis (r=0.622, P<0.01), and an increase of exophthalmos by 1 mm was associated with a total orbital volume increment of 0.88 mL. The clinical activity score was correlated with the SIR of the extraorbital muscles (r=0.536, P<0.01) and levels of anti-thyroid-stimulating hormone receptor antibody (r=0.416,P<0.01). The orbital fat volume was significantly greater in TAO patients than in the healthy individuals (P<0.01).

CONCLUSIONIn patients with TAO, the peak increase of orbital fat volume occurs one year after the disease onset. Measurement of the orbital fat volume combined with SIR of the extraorbital muscles can serve as an indicator for determining the optimal timing for intervention of TAO and helps in the evaluation of prognosis of the patients.

OBJECTIVETo establish a new method for rapid and quantitative measurement of orbital fat volume based on magnetic resonance imaging (MRI) data.

METHODSWe collected MRI data from normalized mold and patients with the diagnosis of thyroid-associated ophthalmopathy (TAO). The cross-sectional areas of the orbital fat on each MR image slice were measured to calculate the fat volume on each slice and then the total orbital fat volume. We recorded the time for completing the measurement and assessed the precision, reliability, repeatability and interoperator variations of the results.

RESULTSThis MRI data-based method allowed precise measurement of the orbital fat volumes with an absolute value of the mean percentage difference <1%. This method was fast and the results showed a good repeatability (with CVs <1%), a high reliability (ICC=0.996, 95%CI: 0.985-0.999) and a high interoperator concordance (95%CI of the Bland-Altman: -0.54-0.90).

CONCLUSIONThe novel method we established for orbital fat volume measurement is rapid, accurate, reliable and reproducible with a low learning cost for clinical use.

Objective To explore the value of prenatal MRI in the diagnosis of fetal simple expansion of lateral ventricle(ventriculomegaly), and follow up the nervous system development status after birth. Methods Simple expansion of the lateral ventricle fetus by prenatal MRI examination were collected in Huzhou Maternal and Child Care Hospital from May 2013 to June 2015, 126 cases of live births in expansion group, 50 normal cases were recruited in the same period as the control group. In expansion group, fetal subgroup analysis was done:(1) unilateral or bilateral lateral ventricle expasion:one group was 98 cases was lateral ventricle expansion (77.8%, 98/126), expansion of bilateral ventricle group was 28 cases (22.2%, 28/126). (2) Prenatal MRI in the diagnosis of the lateral ventricle of expansion: expansion of the lateral ventricle width was greater than 10.0 mm, if both sides were expanding, the expand width was the heavier one side, divided into 3 subgroups: ①Expansion in group A (lateral ventricle width 10.0-12.0 mm) were 88 cases (69.8%, 88/126).②Expansion in group B (lateral ventricle width 12.1-15.0 mm) were 29 cases (23.0%, 29/126). ③Expansion of group C (lateral ventricle width> 15.0 mm) were 9 cases (7.12%, 9/126). All 176 cases were followed up after birth at the 3rd, 6th, 12th, 18th month (corrected age was used for premature babies), and Gesell developmental schedules (GDS) were used to evaluate the neurobehavioral development. Results (1) The MRI results after birth:21 cases were followed up by MRI after birth. In group A, 11 cases had MRI and 9 were normal (the ventricular width<10.0 mm after birth) , the other 2 cases were stable (the ventricular width measured first time after birth was ≥10.0 mm, but the difference was within 2.0 mm from the MRI before birth). In group B, 4 cases had MRI, 1 was normal, 1 was stable, and 2 cases were getting better (the ventricular width measured first time after birth was ≥10.0 mm, but the width decreased more than 2.0 mm from the MRI before birth). In group C, 6 cases had MRI. 3 cases were getting better and 3 cases were stable. (2) Overall GDS results:expansion group after the birth of the 3rd, 6th, 12th, 18th month GDS evaluation results compared with control group, respectively, the differences were not statistically significant (all P>0.05). (3) The GDS results among the subgroups:in each evaluation after birth, there were no statistically significant differences between group A and the control group (all P>0.05). The GDS results of group B at the 3rd and 6th month were lower than those of the control group (P<0.05); while there were no statistically significant differences between the 2 goups at the 12th and 18th month (P>0.05). And for group C, statistically significant differences were found compared to the control group at each follow-up time (all P<0.05). (4) GDS results at different times after birth in the expansion group:there was no statistically significant difference between the results at the 3rd and 6th month (P>0.05). But when the result at the 3rd month was compared to the results of the 12th or 18th month, the differences were statistically significant (P<0.05). GDS result of 6th months after birth compared with 12th and 18th months, respectively, there were no statistically significant differences (P>0.05). There was no statistically significant difference between the results at the 12th and 18th month (P>0.05). (5) The GDS results in unilateral and bilateral ventricle expansion:at the 18th month, among the 98 unilateral cases, 86 (87.8%, 86/98) had normal GDS results(>85 scores);8 (8.2%, 8/98) had borderline results (75-85 scores);4 (4.1%, 4/98) had delayed results (<75 scores). Among the 28 bilateral cases, 23 (82.1%, 23/28) had normal GDS results;3 (10.7%, 3/28) had borderline results; 2 (7.1%, 2/28) had delayed results. There was no statistically significant difference (P>0.05). Conclusions Among the simple expansion of lateral ventricle, those whose ventricular width are≤12.0 mm may not need clinical treatment. If the width is between 12.1 to 15.0 mm, closely follow-up and targeted rehabilitation training after birth are recommended. When the width is more than 15.0 mm, the risk of the central nervous system function delay is significantly increased, and early intervention might improve the prognosis.

OBJECTIVETo investigate the effects of intragastric administration of Clostridium butyricum in regulating serum uric acid, lipopolysaccharides (LPS), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in rats with hyperuricemia rats.

METHODSForty SD rats were randomized into 4 equal groups, namely the normal control group, hyperuricemia model group, benzbromarone (3 mg/kg daily) intervention group and live Clostridium butyricum group (1.5×10CFU/day). Except for those in the control group, the rats were subjected to intragastric administration of yeast extract and oteracil potassium once daily for 12 weeks to induce hyperuricemia with corresponding treatments. The changes in serum uric acid, lipopolysaccharides , IL-6 and TNF-α in each group were detected.

RESULTSThe serum level of uric acid was significantly higher in rats fed with high-purine diet than in the control rats (P<0.01), demonstrating the successful establishment of hyperuricemia models. In rats with hyperuricemia, serum uric acid level was positively correlated with the levels of LPS, IL-6 and TNF-α, and their serum levels decreased significantly and progressively with time in Benzbromarone group and Clostridium butyricum group. Benzbromarone was more effective in decreasing serum uric acid in the rats, while Clostridium butyricum produced a stronger effect in down-regulating the inflammatory mediators.

CONCLUSIONChronic inflammatory reaction exists in rats with hyperuricemia. Intragastric administration of Clostridium butyricum can effectively decrease serum uric acid level and inhibit the inflammatory cytokines, and thus contributes to immune homeostasis in the intestines.
