Objective·To investigate the correlation between the serum haptoglobin (Hp) level and the metabolic parameters in patients with polycystic ovarian syndrome (PCOS), and explore the distribution of Hp genotype and allele frequency in PCOS patients and their correlations with PCOS. Methods·A total of 106 patients with PCOS and 86 cases of patients with non-hyperandrogenic and regular menstruation (control group) were enrolled. Serum Hp level was measured by enzyme-linked immunosorbent assay (ELISA); Hp genotype and allele frequency were determined by polymerase chain reaction (PCR), respectively. Results·The serum Hp level in PCOS group was significant higher than that in the control group (P=0.000). Correlation analysis reveals that serum Hp level was positively related to body mass index (BMI) (P=0.000) and homeostatic model assessment insulin resistance (HOMA-IR) (P=0.000). Compared with control group, proportion of Hp2-2 genotype (Hp2/Hp2) increased significantly in PCOS group (P=0.006), and the frequency of Hp2 allele was also higher (P=0.002). Conclusion·Serum Hp level was positively related to BMI and HOMA-IR, which maybe associated with the occurrence and development of obesity and insulin resistance. Patients with Hp2-2 genotype might have genetic predisposition to PCOS, and high frequency Hp2 allele was found in them.

Objective To evaluate the feasibility of application of video-laparoscopy to the treatment of acute severe inflammatory pelvic pain in women. Methods Forty-two women patients with severe acute inflammatory pelvic pain were divided randomly into two groups with 21 patients in each group. Conservative therapies were carried out in Group A while laparoscopic operations in Group B. Results Eighteen cases (85.7%) in Group A returned to health, and in the remaining 3 (14.3%), conservative measures failed and thus exploratory operations were performed. Meanwhile all the patients in Group B were treated successfully, with the operative time (42.5?20.6) min, the average blood loss 20ml and the mean hospital stay 7 days. Body temperatures returned to normal on the day of operation and no complications occurred. Conclusions Laparoscopy may be feasibly applied to the treatment of women with severe acute inflammatory pelvic pain, producing results superior to conservative therapies.

Objective To study the effect of expansion ex vivo on the hematopoietic reconstitution of umbilical cord blood (UCB) hematopoietic cells, and to find a probable way of UCB transplantation (UCBT) to be used on adults. Method Three groups of UCB hematopoietic cells were transplanted to lethally irradiated BALB/C mice: fresh cells, a half part of fresh cells and a half part of cells expanded for a week, cells expanded for a week. Results All the three groups of cells could reconstitute hematopoiesis. The cells in the latter two groups could more rapidly accelerate the recovery of early-period hematopoiesis. The death rate of the mice in second group was the lowest among three groups. Conclusion The way transplanted with a half part of fresh UCB hematopoietic cells and a half part of UCB hematopoietic cells ex vivo expanded for a week may be a probable one for adult UBCT.

Objectives To analyze SLC37A4 gene mutations in glycogen storage disease type Ⅰb patients and to investigate the correlation between genotype and phenotype. Methods The clinical data and SLC37A4 gene detection results of 3 cases of glycogen storage disease type Ⅰb were analyzed retrospectively. Results Two males and one female aged 6 years, 9 years, and 16 years respectively were presented with hepatomegaly, fasting hypoglycemia, slactic academia, hyperlipidemia, and granulocytopenia. The analysis of 6 alleles in SLC37A4 gene by direct sequencing of peripheral blood DNA found 4 mutations, including 2 missense mutation (p. Leu23Arg and p.Pro191Leu), one shear mutation (c.870+5G>A), and one deletion mutation (c.1042_1043 del CT). The genotypes of these 3 cases were p.Pro191Leu, p.Pro191Leu;p. Leu23Arg, c.870+5G>A;p.Pro191Leu, p.Leu347ValfsX53 respectively. Conclusions There were 4 mutations detected among these 3 cases of glycogen storage disease type Ⅰb. All of those were known mutations. The most common mutation was p.Pro191Leu. It can not be excluded that P.Gly149Glu homozygous mutation is associated with repeated infections.

Objective:To investigate the effect of NS-398,a selective cyclooxygenase-2(COX-2) inhibitor,on the proliferation and invasion of human colon carcinoma cells in vitro,so as to determine the possibility of COX-2 as a new target for treatment of colon carcinoma.Methods: The expression of COX-2 in colorectal cancer cells(CW-2,COLO-320) was detected by RT-PCR and Western blotting.COLO-320 cell proliferation was measured by MTT after treatment with NS-398.Cell invasion ability was measured using migration and invasion chamber systems.Western blotting assay was used to examine the influence of NS-398 on MMP-2 expression.Results: Our results showed that CW-2,COLO-320 cells expressed COX-2 mRNA and protein.NS-398 inhibited the proliferation of COLO-320 cells in a time-and concentration-dependent manner.Invasion test showed that NS-398 inhibited the migration and invasion of COLO-320 cells.Western blotting revealed that NS-398 inhibited the expression of MMP-2 in COLO-320 cells.Conclusion: The selective COX-2 inhibitor NS-398 can inhibit COLO-320 cell proliferation and invasion,indicating COX-2 may serve as a new target for colon carcinoma treatment.

Objective To assess the renal protective effects of triptolide treatment in type 2 diabetic rats and its possible mechanisms.Methods Wistar rats were randomized to receive following approach control (n=7),dia- betic model without treatment (n=7) and diabetic group treated with triptolide[200 ?g/(kg?d),n=7].Plasma glucose (PG),serum creatinine (Scr),total cholesterin (TC),triglyeride (TG),kidney mass (KM),index number of kidney hypertrophy (KM/body mass,KM/BM),and 24 hours urinary albumin (24 h UAL) were determined. The protein expression of monocyte chemoattractant protein-1 (MCP-1),osteopontin (OPN) and ED-1 in renal tissue were determined by immunohistochemical technique.The mRNA expressions of MCP-1 and OPN in kidney tissue were assessed by reverse transcription-polymerase chain reaction (RT-PCR).Results Elevated 24 h UAL was markedly attenuated by triptolide treatment [24 h UAL,triptolide:2.32?0.29 vs diabetic model group:3.89? 0.51 mg/mgCr,P

Objective To study the relationship between the changes of ten elemental contents in serum and schizophrenia.Methods Calcium (Ca), magnesium (Mg), zinc (Zn), iron (Fe), aluminum (Al), arsenic (As), selenium (Se), copper (Cu), lead (Pb), manganese (Mn) in serum in the of schizophrenic patients and normal subjects are measured by inductively coupled plasma mass spectrometer and inductively coupled plasma emission spectrometer, compared the content of elements between the schizophrenia and normal.Results There were significant differences ( P<0.05) in other elements between two groups except lead.The contents of Ca,Fe,Mg,Zn,As,Se,Cu in the patients with schizophrenia were significantly lower than those in control, while Al, Mn were significantly higher than those in control.Most of elements in serum between case and control groups were correlated (P<0.05).Some of element ratios which have physiological significance were significant statistically (P<0.05), such as: Ca/Mg, Ca/Fe and so on.Conclusion These findings suggest that the patients with schizophrenia might have an abnormal elemental metabolism.Given the relationship among the elements, the element ratios are more valuable in reflecting the relationship between schizophrenia and elements.

Objective To investigate the risk factors of mild cognitive impairment (MCI) in patients with type 2 dia-betes (T2DM), and the clinical evidence for the early diagnosis and treatment thereof. Methods A total of 217 T2DM pa-tients were divided into T2DM with MCI group (n=92) and T2DM with normal cognitive function(NMCI) group (n=125). Mon-treal cognitive assessment scale (MoCA) and activities of daily living scale (ADL) were used to assess the functional status in two groups of patients. The general clinical data and biochemical indicators were obtained and compared in two groups. Re-sults There were statistical differences in age, smoking history, education status, high sensitive C reactive protein (hs-CRP), coronary heart disease, hypertension, glycated hemoglobin A1c (HbA1c) and T2DM history between two groups. Re-sults of univariate logistic regression analysis showed that old age, longer course of T2DM, smoking history, higher hs-CRP and HbA1c, complicated with coronary heart disease and hypertension were risk factors for T2DM with MCI, while the higher education status was a protective factor. Multiple logistic regression analysis showed that old age and longer T 2DM history were risk factors, and the higher education was a beneficial factor for T2DM with MCI. Conclusion Many risk factors may play a part in T2DM with MCI. Early detection and prompting medical attention may help prevent and decrease the preva-lence of MCI in patients with T2DM.
