Objective:To establish an HPLC method with a refractive index detector for the simultaneous determination of fructose and glucose in multiple electrolytes and invert sugar injections. Methods: A Waters XbridgeTM Amide(150 mm × 4. 6 mm,3. 5 μm) column was used with acetonitrile-water -triethylamine (75∶25∶0. 2) as the mobile phase, the column temperature was 40 ℃, the flow rate was 1. 0 ml·min-1 , the refractive index detector was used with the detector temperature of 40 ℃, and the injection volume was 50 μl. Results:A good linear relationship between the quantity of glucose or fructose and peak area was shown within the range of 99. 8-149. 7 μg(r=0. 999 7)for fructose and 100. 3-150. 4 μg(r=0. 999 2)for glucose, the average recovery of fructose and glucose was 99. 2% and 99. 5% with RSD of 0. 81% and 0. 84%(n=9), respectively. Conclusion: The method is fast and convenient with high specificity, good accuracy and promising separation, which can be used in the content determination of fructose and glucose in multiple electrolytes and invert sugar injections.

Objective To establish the ELISA method by using synthetic peptide for detection of IgM antibodies to human cytomegalovirus(HCMV).Methods According to HCMV PP150 sequence of amino acid and nucleotide,the peptide sequence was decided by computer with some program of software of protein.The ELISA method using synthetic peptide as antigen was developed and was applied to detected anti-HCMV IgM in sera of normal pregnant woman and habitual abortion woman.The HCMV DNA were detected by polymerase chain reaction(PCR).Results The positive rates of anti-HCMV IgM in different populations were as follows:9 17%(11/120) in normal pregnant woman,37 5%(24/64) in habitual abortion woman.The ELISA method have good speciality.The positive rate of HCMV DNA was significantly related to that of anti-HCMV IgM(P

Objective To observe the serum lipid level of patients with branch retinal vein occlusion (BRVO).Methods A total of 71 BRVO patients (BRVO group) were enrolled in this study.The patients included 31 males and 40 females,with an average age of (52.75 ± 10.2) years.All the patients were examined for visual acuity,slit lamp ophthalmoscopy combine with preset lens,fundus color photography and fundus fluorescein angiography (FFA) examination.Seventy-two age-and sex-matched normal subjects were enrolled in this study as control group.The subjects included 32 males and 40 females,with an average age of (53.10±9.5) years.The BRVO and control group were divided into four subgroup which including age with ＜40 years,40-49 years,50-59 years and ≥60 years.The plasma cholesterol and triglyceride level of BRVO group,control group,and age subgroups of BRVO and control group were comparatively analyzed.Results The average plasma cholesterol levels were (4.529±0.100) and (4.274±0.106) mmol/L in BRVO and control group,respectively.There was no difference between two groups (t=-1.738,P＞0.05).The average triglyceride levels were (1.500±0.129) and (1.319±0.095) mmol/L in BRVO and control group,respectively.There was no difference between two groups (t=-1.135,P＞0.05).There was no difference of average plasma cholesterol (t=-1.755,1.850,-1.892,-0.507) and triglyceride (t=0.846,-0.074,-1.288,-1.887) level in age subgroups of BRVO and control subgroup (P＞0.05).Conclusion There is no significant difference of serum lipid level between BRVO patients and controls.

0.05,compared with using 1.75 mmol/L calcium dialysate.The serum iPTH increased significantly,P0.05.Conclusion 1.25 mmol/L or 1.50 mmol/L lower-calcium dialysate can elevate the level of serum iPTH in MHD patients.

The pathogen of Kawasaki disease(KD) is still unknown although infection is considered as the most possibility factor.However epidemiologic studies showed that genetic background might be a main factor in the onset of KD.The recent papers on gene polymorphism including angiotensin-convertion enzyme,nitric oxide synthase and cytokine related with KD were searched and analyzed in this review.

Diffuse large B-cell lymphoma (DLBCL) is one of the most common non-Hodgkin lymphomaaccounting for 30 %-40 %. The most common first-line therapy for DLBCL is rituximab in combination withchemotherapy. About two thirds of patients treated by the first-line therapy achieve a complete remission (CR)and are cured finally, but nearly one third of patients can not reach CR after frontline treatment appearingrefractory or relapse early, especially for the high risk patients or cases with MYC alterations, the regimenimproving the long-term survival is not much. In the 57th American Society of Hematology (ASH) annualmeeting, a plenty of treatment as focus on these patients brought in encouraging results, which makes itpossible to further improve the CR rate. The progresses on DLBCL of relapse and refractory, high risk andspecial types were summarized in this paper based on the reports in the 57th ASH annual meeting.

Objective:To observe the therapeutic effect of Governor Vessel-unblocking and yang-regulating acupuncture plus chiropractic treatment on upper cervical spondylosis. Methods:A total of 64 eligible cases were randomly allocated into an observation group (n=32) and a control group (n=32) according to the random digital table. Cases in the observation group were treated with Governor Vessel-unblocking and Yang-regulating needling method, fine adjustment of the upper cervical spine and lumbosacral Ban-pulling manipulation; cases in the control group were treated with routine acupuncture and same spinal adjustment as the observation group. The treatment was done once a day in both groups. The therapeutic efficacies were observed after 10 times of treatment. Results:The total effective rate was 78.1% in the observation group and 67.5% in the control group. The difference in the total effective rate between the two groups was statistically significant (P<0.05). Conclusion:Governor Vessel-unblocking and yang-regulating acupuncture and regulate yang plus chiropractic therapy is better than routine acupuncture plus chiropractic therapy in the therapeutic effect in the treatment of upper cervical spondylosis.

BACKGROUND:Studies have indicated that melatonin can promote the differentiation of adipose-derived stem cels into neurons, and the effect of melatonin on the osteoblasts form adipose-derived stem cels is rarely reported.
OBJECTIVE:To observe the osteogenic differentiation of adipose-derived stem cels and the effect of melatonin on the bio-viability of differentiated cels.
METHODS:(1) Adipose-derived stem cels were isolated and purified from the inguinal fat of Kunming mice by type I colagenase digestion and differential adhesion method, respectively. Immunohistochemical staining of CD44 was used as a quality control. (2) Osteogenic induction medium was added to induce osteogenic differentiation of passage 2 adipose-derived stem cels. Alkaline phosphatase staining and von Kossa method were combined to evaluate differentiation condition. (3) Melatonin at variable concentrations was added to treat mature osteocytes originated from adipose-derived stem cels and MTT was applied to determine their viability at 24 and 48 hours after culture respectively to find out optimal condition of melatonin treatment. (4) Melatonin at the optimal concentration was used to treat differentiated cels and detect alkaline phosphatase activity after 3 days and 6 days respectively.
RESULTS AND CONCLUSION: (1) After seeding for 48 hours, most cels were adherent, and after 4 days, the cels displayed multiple shapes and colonies of different sizes formed. After subculture, cel morphology homogenized as spindle shape. Cels positive for CD44 were brownish yelow, and localized mainly on the cel membrane. (2) Differentiated cels were positive for von Kossa staining and black sediments scattered in the extracelular matrix. Alkaline phosphatase expressed positively, and brown-black particles, appeared within cels. (3) Melatonin supplement improved the viability of differentiated cels; and 1, 10 and 100 μmol/L was observed as the optimal concentrations both at 24 and 48 hours. (4) The intracelular alkaline phosphatatse activity was increased with time in al the groups (P < 0.05). Compared with the blank group, the intracelular alkaline phosphatase activity in Melatonin groups (1, 10 and 100 μmol/L) had nochanges at 3 days, but significantly increased at 6 days (P < 0.05). These findings indicate that melatonin can enhance the proliferation of osteocytes differentiated from adipose-derived stem cels, and improve the activity of intracelular alkaline phosphatase.
