Objective To investigate the effect of electroacupuncture (EA) on oocyte quality in patients with polycystic ovary syndrome (PCOS) undergoing in-vitro-fertilization and embryo transfer (IVF-ET).Method Totally 217 patients with PCOS undergoing IVF-ET were randomized into two groups by the random number table, 119 patients in an EA group and 98 in a control group. In addition to the long-term ovarian hyperstimulation given to the two groups, electroacupuncture was involved in the intervention in the EA group. The spindle, quality of eggs, and pregnancy result were observed and compared.Result The high-quality embryo rate was significantly higher in the EA group than the control group (P<0.05), and compared to the control group, the pregnancy rate was 8.36% higher in the EA group; it’s found that the number of eggs with spindle located between 11 and 1 o’clock was in a significant positive correlation with the level of E2 on the HCG administration day and the high-quality embryo rate (P<0.01); the EA group had a markedly higher ratio of eggs with spindle located between 11 and 1 o’clock compared to the control group (P<0.05); electroacupuncture markedly reduced the dosage and duration of using Gn in the PCOS patients (P<0.05). Conclusion It’s proven the relation between spindle and the quality of eggs; electroacupuncture can enhance the quality of eggs and the pregnancy rate in the PCOS patients.

OBJECTIVETo observe the effect of electro-acupuncture (EA) treatment on the oocyte quality in polycystic ovarian syndrome (PCOS) patients undergoing in vitro fertilization-embryo transfer (IVF-ET).

METHODSTotally 217 PCOS patients undergoing IVF-ET were assigned to two groups by random digit table, the EA group (119 cases) and the control group (98 cases). All patients received long program ovarian hyperstimulation with gonadotropin-releasing hormone agonist. Patients in the EA group received EA treatment in the process of controlled ovarian hyperstimulation till the oocyte retrieval day. The position relation of the spindle to the polocyte, the number of retrieved oocytes, the fertilization rate,the cleavage rate,the high quality embryo rate, the ovarian hyperstimulation syndrome (OHSS) incidence rate, the clinical pregnancy rate, the early abortion rate, the gonadotropins (Gn) dose and time, levels of estradiol (E2), progesterone (P), and luteinizing hormone (LH) on the day of human chorionic gonadotropin (HCG) were observed between the two groups.

RESULTSThe ratio of oocytes in which the meiotic spindle deviation angle was < 60 degrees to the all oocytes was obviously higher in the EA group than in the control group (P < 0.05). The oocytes in which the meiotic spindle deviation angle was < 60 degrees was positively related to level of E2 on the HCG day and the high quality embryo rate (r = 0.19,P < 0.01). Compared with the control group, the high quality embryo rate increased significantly (P < 0.05), the dose and days of Gn decreased significantly (P < 0.05) in the EA group. The clinical pregnancy rate was improved by 8.36%.

CONCLUSIONSThe spindle was positively correlated with the oocyte quality. EA could improve the quality of oocytes and the clinical pregnancy rate in PCOS patients undergoing IVF-ET.

OBJECTIVETo explore the distribution characteristics of basic syndromes and its related factors in patients with chronic functional constipation (CFC).

METHODSThe complete data of 538 patients with CFC were collected and initial database was established with Epidata 3. 0. TCM syndrome typing was performed. The distribution characteristics of basic syndromes were analyzed using SPSS 17. 0 Software. The univariate and multivariate Logistic regression analyses were performed with SPSS 17. 0 Software to determine basic syndrome related factors such as age, engaged professionals, sleep quality, depression, mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation, and so on.

RESULTSThe TCM syndrome frequency of CFC patients was sequenced from high to low as qi deficiency syndrome (380 cases, 70.6%), qi stagnation syndrome (337 cases, 62.6%), blood deficiency syndrome (234 cases, 43.5%), yin deficiency syndrome (220 cases, 40.9%), yang deficiency syndrome (197 cases, 36.6%), and others(58 cases, 10. 8%) . Most patients were complicated with complex syndromes, and the most common complex syndromes were qi deficiency complicated qi stagnation syndrome (275 cases, 51.1%) and qi deficiency complicated blood deficiency syndrome (222 cases, 41.3%). Aging, work fatigue, and exercise conditions were main related factors for qi deficiency syndrome (P <0. 01, P <0. 05). Poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, defecation barriers constipation were main related factors for qi stagnation syndrome (P <0.01). Sleep quality and poor emotional (depression and anxiety tendencies) were main related factors for blood deficiency syndrome (P <0. 01, P < 0.05). Stimulating beverages were main related factor for yin deficiency syndrome (P <0.05). Engaged in mental work and slow transit constipation were main related factors for yang deficiency syndrome (P < 0. 01, P <0. 05).

CONCLUSIONSCFC is featured as complex syndromes. The most common complex syndromes were qi deficiency complicated qi stagnation syndrome and qi deficiency complicated blood deficiency syndrome. Basic syndrome related factors such as age, engaged professionals, sleep quality, poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation were associated with the distribution of CFC syndromes.

OBJECTIVETo study the expression of Mucin1 gene and tumor infiltrating dendritic cells(TIDC) in the tissues of benign prostatic hyperplasia (BPH) and prostate cancer.

METHODSMucin1 and TIDC were detected in 20 specimens of BPH and 30 specimens of prostate cancer by immunohistochemistry SP method.

RESULTSMUC1 expressed in both prostate cancer and BPH. The staining patterns were significantly associated with tumor pathological grade (P < 0.001). The number of TIDC was negatively correlated with tumor pathological grade, the higher the grade, the smaller the number of TIDC (P < 0.001).

CONCLUSIONSThe expression pattern of MUC1 and the number of TIDC could be considered as useful markers to evaluate the malignant degree and prognosis of prostate cancer. The decrease of TIDC plays an important role in tumor immune evasion and immune tolerance. Highly expressed MUC1 could lead to the failure of hormonal treatment for prostate cancer, and contribute much to tumor infiltration and metastasis.

OBJECTIVETo explore the program of preoperative evaluation, preoperative preparation and separation operation of pygopagus conjoined twins.

METHODSClinical data of one case of pygopagus (male, gestational age 37 weeks, uterine-incision delivery, 3.5 months old; twins of triplets; total body weight 8.0 kg. The twins have self-governed extremities, anus, penis. Four limbs can move independently). Separated successfully were analyzed. The auxiliary examination of X-rays, MRI, ultrasound, CT and 3D reconstruction, sensory evoked potential showed that there were process hypoplasia and lamina bifid of lumbosacral vertebrae below L3. Dural sac connected below L3 and conus medullaris located at L3. There were no conjunction of spinal cord and cauda equine. The decision of direct suture of dural sac was made by preoperative evaluation through measurement of circumference and area of conjoined dural sac. The separation surgery program was decided through team debate and sham operation. Separation operation was performed under the general anaesthesia. Crossing V-shaped skin flap was used to cover the wound surface. The dura of conjoined twins were sutured directly. The tension of skin flap was normal postoperative with continuing negative pressure drainage under the flap and pressure sterilized dressing.

RESULTSSuccessful separation of pygopagus conjoined twins was achieved. Lower extremities movements of separated twins were normal 6 h after operation. The drainage was removed 1 day postoperative, blood supplies of skin flap were normal. There were no complications of infection, cerebrospinal fluid leakage and neurological deficit. The healing of the skin flap was good. With 6 months follow-up, the growth and neurological function were normal.

CONCLUSIONConsummate preoperative preparation, accurate preoperative investigations, meticulous operative management, careful postoperative administration and good team cooperation are the keys to successful separation of pygopagus conjoined twins.

OBJECTIVETo explore the impacts of electroacupuncture on embryo implanted potential and its molecular mechanism in the patients with infertility of different symptom complex.

METHODSAmong the patients with infertility treated with electroacupuncture and in vitro fertilization and embryo transplantation (IVF-ET), 82 cases of kidney deficiency (group A), 74 cases of liver qi stagnation (group B) and 54 cases of phlegm dampness (group C) were selected. All of the patients in three groups received long-program ovarian hyper-stimulation. Additionally, electroacupuncturecan was applied before controlled ovarian hyper-stimulation (COH) and in the process of ovarian hyper-stimulation. The levels of human leukocyte antigen-G (HLA-G) in the serum were determined on the 2nd day of the menstruation (M2), on the day of human Chorionic Gonadotropin (hCG) injection and on the day of embryo transplantation in the culture solution in three groups separately. The fertilization rate, implantation rate and clinical pregnancy rate were observed for the patients in three groups.

RESULTSThe levels of HLA-G in the serum on hCG injection day and in the culture solution on embryo transplantation day in group A and B were significantly higher than those in group C (all P < 0.05). But, there was no significant difference in serum HLA-G levels on M2 day among three groups. The high-quality embryo rate in either group A (73.6%, 352/478) or group B (70.6%, 379/537) was higher significantly than that in group C (54.2%, 208/384) separately, presenting statistical significant difference (all P < 0.01). But there were no significant differences in clinical pregnancy rate, fertilization rate and cleavage rate among three groups.

CONCLUSIONElectroacupuncture can increase the contents of HLA-G in the body and the level of HLA-G secreted in embryos for the patients in the process of IVF-ET. Eventually, the pregnancy outcome and the pregnancy rate are improved. The clinical effects of electroacupuncture for the patients of kidney deficiency and liver qi stagnation are better than those for the patients of phlegm dampness.

OBJECTIVESTo explore the thrombin generation capacity in patients on warfarin therapy with different prothrombin time international normalized ratio (PT-INR), the capacity in relation to bleeding, and the application of thrombin generation tests to warfarin therapy monitoring.

METHODSSeventy eight blood samples were taken from patients on warfarin therapy for more than 3 months owing to valve replacement or atrial fibrillation. The patients' case history and PT-INR were collected and thrombin generation tests were performed in all samples.

RESULTSPatients were ranked into three groups according to different PT-INR. There were 23 patients in group I with PT-INR from 1.51 to 2.00, 39 patients in group II with PT-INR from 2.01 to 3.00, and 16 patients in group III with PT-INR from 3.01 to 4.26. There were significant differences between each two of the three groups in lag time, peak, and ttpeak (time to peak) (P <0.01). There was a significant difference between group I and group II in endogenous thrombin potential (ETP) (P = 0.0001), but not between group II and group III (P= 0.06). Five patients developed bleeding and their ETP was less than 15% of normal control.

CONCLUSIONIn patients on warfarin therapy, when the PT-INR was more than 3.0, increasing the dose of warfarin doesn' t decrease the thrombin generation, but increase bleeding risk. PT-INR combined with ETP may better reflect patient's coagulation status, therefore be of more significance in preventing bleeding.

OBJECTIVETo analyze the phenotype and genotype of two Chinese pedigrees with von Willebrand diseases, and to investigate the molecular pathogenesis.

METHODSBleeding time (BT), activated partial thromboplastin time (APTT), ristocetin-induced platelet aggregation (RIPA), von Willebrand factor-ristocetin cofactor (vWF:Rco), von Willebrand factor antigen (vWF:Ag), von Willebrand factor activity (vWF:A), von Willebrand factor collagen binding assay (vWF:CB) and multimer analysis were used for phenotype diagnosis. DNA was extracted. All of the 52 exons and exon-intron bounda ries of the VWF gene were amplified with polymerase chain reaction(PCR) and analyzed by direct sequencing.

RESULTSAPTT and BT were prolonged. Plasma RIPA, vWF:Rco, vWF:Ag, vWF:A and vWF:CB was significantly decreased. No VWF multimer can be found by plasma VWF multimer analysis. Homozygous insertional mutation g.82888_82889insCATG in exon 17 was found in proband A. Compound heterozygous mutations g.94865 G to A (Trp856stop) in exon 20 and g.110698_110699delinsG in exon 28 were found in proband B.

CONCLUSIONHomozygous insertional mutation g.82888_82889insCATG and compound heterozygous mutations g.94865G to A(Trp856X) and g.110698_110699delinsG probably have respectively induced type 3 von Willebrand diseases in the two probands.

OBJECTIVETo investigate the mechanism of serum testosterone reduction, its relationship with metabolism, changes in the number and morphology of Leydig cells and endocrine function in aging male rats.

METHODSThe levels of serum total testosterone (tT), LH, FSH, HDL, LDL, TG, TC, Glu, INS, IRG and LP were determined in young (9 mo) and aging rats (12, 15, 18 and 21 mo), with 6 in each group. The morphological changes of Leydig cells were observed under the microscope. The concentrations of testosterone secreted from the cultured Leydig cells with the stimulation of hCG and Forskolin were assayed. The apoptosis rates of Leydig cells were detected by TUNEL. The visceral fat was isolated and weighed, and the Lee's index calculated. All the above indexes were recorded and compared among different age groups.

RESULTSThe aging rats showed a significant decrease in the levels of serum tT and TSI ([1.26 +/- 0.65] ng/ml and [0.07 +/- 0.65] ng/mIU) as compared with the young rats ([3.24 +/- 0.38] ng/ml and [0.21 +/- 0.01] ng/mIU) (P < 0.01). Obvious differences were found in the morphology of Leydig cells among different age groups. The T secretion of Leydig cells at 24, 48 and 72 h in aging rats was markedly decreased (P < 0.05) while their TUNEL positive rate remarkably increased in the aging rats (17.36% +/- 1.31%) compared with the young ones (7.02% +/- 1.05%) (P < 0.05). There were statistically significant differences between the young and aging rats in all the biochemical parameters including IRG, HDL, LDL, TG, TC and visceral fat content (P < 0.05), except the levels of serum Glu, INS and LP (P > 0.05).

CONCLUSIONThe serum T level and secreting capacity of Leydig cells are significantly lower in aging rats than in young ones, and the metabolic parameters undergo regular changes with the decreasing level of serum T. The reduction of testosterone in aging male rats may be associated with the decreased secreting capacity and number of Leydig cells and declined function of the pituitary.
