Objective To study the curative effect of limited-acupotomy therapy on chronic lumbosacral osteo-fascial compartment syndrome. Methods 59 patients were randomly recruited into a control group (with 29 patients) and a treatment group (with 30 patients). The control group was treated with general-acupotomy therapy, and treatment group was treated with limited-acupotomy therapy. Evaluate the curative effects before the first and the second therapy, and 3 months after the therapy respectively, as well as VAS pain, JOA and CODI scores. Results The curative effect was 96.56% and 100% respectively in the control group and the treatment group 3 months after the treatment. The difference between the two groups was not statistically significant(χ2＝0.19,P＞ 0.05). As to VAS pain scores, JOA and CODI scores, the difference among the three stages of the treatment were significant (in control group F＝165.70, 99.90, 106.60 respectively, in treatment group F＝279.76, 154.34, 67.36 respectively, P＜0.01)in both groups respectively, but the difference between the two groups were not significant(P＞0.05) in each stage. Conclusion Limited-acupotomy therapy was safe and effective in treating chronic lumbosacral osteo-fascial compartment syndrome.

Objective To estimate the test-retest reliability of limits of stability (LOS) measurement in healthy young adults. MethodsTwenty-five healthy young adults participated this study.Their center of pressure (COP) displacements were recorded while they stood on a force platform.The subjects performed maximal voluntary sway maneuvers in the anterior,posterior,left and right directions in turn.The LOS in each direction was calculated using balance clinic software.Each subject underwent 3 consecutive,identical tests at 7 day intervals with the same investigator.The test-retest reliability of LOS was analyzed using the intraclass correlation coefficient (ICC).ResultsFor the first test the ICC values ( ICC1 ) of the LOS ranged from 0.790 to 0.857.For the mean LOS of the first two tests the ICC2 ranged from 0.906 to 0.937,and for the mean LOS of three tests the ICC3 ranged from 0.910 to 0.948. ConclusionThe LOS test is a reliable measurement with healthy young adults.In clinical practice,averaging two LOS tests is suggested in assessing balance and postural control with young adults.

Objective To determine normal reference values for conduction in the posterior antebrachial cutaneous nerve.Methods Antidromic sensory conduction examinations of the bilateral posterior antebrachial cutaneous nerve were conducted with fifty-eight healthy subjects.The onset latency,peak latency,peak-to-peak amplitude and conduction velocity of the sensory nerve action potentials (SNAPs) were recorded and the inter-side ratios of the peak-to-peak amplitudes were calculated.Results The observed means (and standard deviations) of the onset time,the peak latency,the amplitude and the conduction velocity were 1.96 (0.12) ms,2.48 (0.14) ms,7.39 (2.36) μV and 61.39 (3.69) m/s,respectively.The side-to-side amplitude ratio (smaller/larger) was 0.88 ± 0.09,and no significant difference was observed between the left and right side.The average peak latency and amplitude were significantly different for different age groups.There was no statistically significant difference among the age groups with regard to onset latency or conduction velocity.Conclusion Conduction in the posterior antebrachial cutaneous nerve is easy to study.The peak latency is prolonged and the amplitude decreases with age,suggesting that different normal reference values should be established for different age groups.

This study was aimed to observe effect of pomegranate leaf tannin and ellagic acid on primary rat adipocyte differentiation and lipid metabolism-related factor expression. Primary rat preadipocyte was in vitro cultured to observe the effect of pomegranate leaf tannin and ellagic acid on lipid fat cells as well as mRNA expression of its related factor. The results showed that pomegranate leaf tannin and ellagic acid had obvious inhibition effect on fat formation in fat cells. It had certain inhibition effect on activities of lipoprotein lipase (LPL) and glucose-3-phosphate dehydrogenase (GPDH). It promoted fat decomposition and reduced intracellular lipid content. It upregulated PPARγ and fatty acid-binding protein (aP2). It downregulated obese (ob) gene level. It was concluded that pomegranate leaf tannin can inhibit fat generation of fat cells and promote fat metabolism. Ellagic acid was its main active ingredient, which had the same effect as pomegranate leaf tannin.

This study was aimed to observe the effect ofpomegranate leaf tennis and Ananas coumosus leaf phenols on the growth of lactating mice through breast milk. Intragastric administration of different doses of drug was given to maternal mice. The general condition of newborn mice, body weight, tail length and organ coefficient of liver-related factors regulating the expression of lipid metabolism were observed. The results showed that both pomegranate leaf tennis and A. coumosus leaf phenols can obviously affect the growth and development of newborn mice through breast milk. And the effect of pomegranate leaf tennis was stronger than A. coumosus leaf phenols. Meanwhile, it obviously downregulated the expression of liver-related lipid metabolism enzymes in newborn mice. It was concluded that pomegranate leaf tennis and A. coumosus leaf phenols can affect the growth and development of newborn mice through breast milk. Its effect was related to the influence of lipid metabolism enzyme in the liver. Attention should be paid on taking this medication during lactation. Its clinical significance still required in-depth study.

Objective To evaluate the clinical efficacy and safety of domestic Sirolimus-eluting stents (Firebird) and imported Zotalimus-eluting stents ( Resolute) in the treatment of patients with unprotected left main coronary artery disease ( ULMCA) . Methods We retrospectively enrolled 76 patients with ULMCA treated by percutaneous coronary intervention (PCI) under the guidance of IVUS in our hospital. According to the different stents used in the procedure, the patients were divided into two groups: Domestic Sirolimus-Eluting Stents group (Firebird group, n = 42) and Imported Zotarolimus-Eluting Stents group (Resolute group, n = 34) . We analyzed the baseline characteristics, coronary artery lesion characteristics, stenting strategies and any changes in left ventricular ejection fraction ( LVEF) in both groups and investigated the long-term clinical outcomes. Results There were no significant differences in the baseline characteristics, the SYNTAX scores of the coronary artery lesion and the rate of complete revascularization between the two groups. Compared with that in Firebird group, there were more cases involving the distal left main (79. 4% vs. 45. 2% , P ﹤ 0. 05) and more patients using two stents strategies (29. 4% vs. 7. 1% , P ﹤ 0. 05) in the Resolute group. The change in LVEF post-PCI had no difference between the two groups. The patients were followed up for a mean of (23. 3 ± 10. 7) months. During the follow-up period, the occurrence of MACCE had no significant difference between the two groups. In the Firebird group, there were one sudden cardiac death, one nonfatal myocardial infarction, one stroke and five patients with recurrence of angina pectoris. In the Resolute group there were one sudden cardiac death, one target lesion revascularization and four patients with recurrence of angina pectoris. Conclusions Compared with the imported Zotalimus-Eluting Stents, the domestic Sirolimus-Eluting Stents are safe and effective in the treatment of patients with unprotected left main lesions under the guidance of IVUS. The two kinds of stent showed similar long-term clinical outcomes.

Objective To characterize the static balance and limits of stability (LOS) of postmenopausal women and evaluate the relationship between bone mineral density (BMD) and balance.Methods Sixty women more than 12 months past menopause and aged 50 to 60 years were included in the study.Group 1 (n =20) consisted of women with normal BMD,group 2 (n =20) women with osteopenia,and group 3 (n =20) women with osteoporosis.The static balance of all the participants was evaluated in upright postural situations for 60 s with the eyes open and with the eyes elosed.Their LOS was quantified using a force platform.Results There was no significant difference in static balance parameters or LOS among the 3 groups.The static balance parameters were not significantly different in either the eyes-open or eyes-closed situation in the osteoporosis and osteopenia groups.The medial and lateral LOS were greater than the anterior and posterior limits in all 3 groups.The anterior LOS was greater than the posterior limits among the women with osteopenia and normal density.Conclusion In postmenopausal women aged 50 to 60 years,BMD did not show any significant association with static balance or LOS.Postmenopausal women had better postural control in the mediolateral than in the anteroposterior direction.In postmenopausal women with osteoporosis,postural control in the anterior direction deteriorates from age 50 to 60.

This article was aimed to study the quality control of pineapple leaf in order to further develop the appli-cations of pineapple leave as medicinal resources. The tissue structure of pineapple leaf was observed by tissue biop-sy assay. Thin-layer chromatography (TLC) was employed on the qualitative identification of ananasate in the leave. The p-coumaric acid and ananasate were detected with high-performance liquid chromatography (HPLC) assay in the content determination. The results showed that pineapple leaf can be divided into the upper and lower leaf epidermis with stoma under microscope observation. Ananasate of the leave can be indentified clearly by TLC. HPLC method can accurately detect the content of p-coumaric acid and ananasate of pineapple leave. There are different contents of p-coumaric acid and ananasate of pineapple leave in different origins. In Y unnan province, the contents of p-coumaric acid and ananasate of pineapple leave are the highest; while the contents of p-coumaric acid and ananasate in Guangxi province are the lowest. It was concluded that ananasate can be used in the quality identification. The p-coumaric acid and ananasate can be used in the quantitative determination in the better control of the quality of pineapple leaf.

ObjectiveTo evaluate the expression of endothelial differentiation gene/lysophosphatidic acid (LPA) receptors (Edg/LPA) and its clinical significance in human pancreatic cancer.MethodsFifty cases of pancreatic cancer and adjacent normal tissues were collected,and Real-time PCR,Western blot and immunohistochemistry was used to determine the expression of Edg-2/LPA1,Edg-4/LPA2 and Edg-7/LPA3 receptors mRNA and protein,and its relationship with clinicopathological parameters was analyzed.Results The expressions of Edg-2/LPA1,Edg-4/LPA2,Edg-7/LPA3 receptor mRNA were (0.142 ± 0.042 ) ％,(0.471 ±0.064)％,(0.231 ±0.043)％ in pancreatic cancer,and the corresponding values were (0.132 ±0.029)％,(0.027 ±0.015)％,(0.163 ±0.046)％ in adjacent normal tissues.The expressions of Edg-4/LPA2 receptor mRNA in pancreatic cancer were significantly lower than that in adjacent normal tissues ( P ＜0.05 ).The expressions of Edg-4/LPA2 receptor protein in pancreatic cancer were significantly lower than that in adjacent normal tissues ( P ＜ 0.05 ).The expressions of three types of Edg /LPA receptor mRNA in pancreatic cancer were parallel to serum CA19-9 levels.The expressions of Edg-4/LPA2 receptor mRNA were associated with tumor size,differentiation degree,and invasive ability and metastasis.While the expressions of Edg-2/LPA1,Edg-7/LPA3 receptor mRNA was associated with invasive ability and metastasis only.ConclusionsEdg-4/LPA2 receptor is highly expressed in pancreatic cancer,which suggesting the malignant biological behavior of pancreatic cancer.

The lack of effective in vitro infection model for hepatitis E virus (HEV) has greatly hindered the quantitative analysis of neutralizing titers of anti-HEV antibodies and human sera, thus impeding further studies of HEV-stimulated antibody responses and the immunological mechanisms. In order to improve this situation, the infection of HepG2 cells that are inefficient for HEV replication was continuously monitored until the viral load reached the limit of detection on day 13, the results of which confirmed the feasibility of using this cell line to establish the infection model. Then, neutralization assays of five anti-HEV murine monoclonal antibodies and serum samples collected from four HEV vaccine recipients (collected before and after vaccination) were performed by 96 multi-channel parallel infections, nucleic acid extraction, and qPCR. The results showed that the cell model can be applied for quantitative evaluation of the neutralizing capacity of different antibodies and antiserum samples from HEV vaccine recipients. In this study, we have successfully established a high-throughput in vitro HEV replication model, which will prove to be useful for the evaluation of HEV vaccines and studies of HEV epitopes.
