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.

Objective To investigate the vision and the eye conditions of the longevous aged 90 years or over Methods The vision was examined by Snellen chart, and the outer eye, anterior segment, fundus and intraocular pressure were examined by slit lamp, funduscope and non contact tonometer in 135 longevous cases Some related examinations were adopted on suspective cases The refractive errors were corrected in 53 cases who were cooperative to examination Results The visions of right eyes were 0 01～1 0 with the average of 0 46?0 50, and the left eyes were 0 03～1 0, with the average of 0 49?0 50. The probabilities of blindness and low vision were 5 93% and 10 27% respectively. In 43 cases (81 13%)the vision increased by 1～5 lines (the average in 3 lines)after optometry compared with pre optometry ( P

ObjectiveTo investigate the visual condition and causes of blindness and low vision of ov er 60 years old people found by routine physical examination. Methods A total of 892 cases over 60 years old people took a yearly routine examinatio n, such as far and near vision in daily life, anterior segment and fundus of the eye and intraocular pressure. If the vision were under 0 3, the refractive vis ion needs to be corrected. The blindness and low vision patients were selected a nd taken further related examinations to analyse statistically the causes of bli ndness. Results Among 892 cases investigated, blindness together with low vision were 42 cases (4 71%). The morbidity rate of blindness and low vision were 1 01% (9 cases) a nd 3 70% (33 cases) respectively. Diseases caused blindness were macular lesio ns (57 14%), glaucoma(11 91%), cataract (9 52%), retinal diseases, optic nerv e atrophy, keratopathy etc. Refractory eye diseases were obviously more than t he eye diseases which can be treated. The morbidity rate of over 80 years old pe ople were obviously more than that of under 80 years group. Conclusions With ageing, the old people easily suffer from eye diseases and results in bli ndness. For the prevention and treatment of blindness for the elderly, much atte ntion to treatment of eye diseases should not only paid, active training is also important.

Objective To investigate the expression and significance of myeloid cell leukemia-1 (Mcl-1 )gene and protein in Hepatocellular Carcinoma(HCC).Methods The expression of Mcl-1 was detected respectively by Reverse Transcription-Polymerase Chain Reaction (RT-PCR),Western blot and ENVISION immunohistochemistry in 20 HCC specimens,19 liver cirrhosis(LC)specimens,and 12 control ones.Their relationship with clinical and pathological characteristics of HCC was investigated.Results The expression of Mcl-1 mRNA in the control group,LC group and HCC group was 0.52±0.17, 3.46±1.7,3.65±2.93,respectively.The level in HCC and LC group was statistically different compared with the control group,respectively (t=7.925,5.334,P<0.05).The relative expression of Mcl-1 protein in LC group (0.51±0.35)and HCC group (0.75±0.36)were significantly higher than that in the control group (0.21±0.19)(t=5.526,6.355,P<0.05).The positive expression rate of Mcl-1 in HCC group was 55.00% (11/20),significantly higher than that in the con-trol group 33.33% (4/12)(t=7.835,P<0.05).The positive expression of Mcl-1 was related to tumor necrosis and TNM staging (χ2=4.201,P<0.05).Conclusion Mcl-1 gene and protein are differentially expressed in HCC,LC and the control, which may be involved in the occurrence,development and malignant transformation of HCC.

OBJECTIVE:To establish a method for the determination of the content and molar ratio of Ornithine aspartate for in-jection. METHODS:HPLC was performed on the column of Thermo HYPERSIL Aps-2 amino column with mobile phase of aceto-nitrile-0.05mol/L Potassium dihydrogen phosphate solution,the flow rate was 0.9 ml/min,the column temperature was 30℃,the de-tection wavelength was 200 nm,and the injection volume of 20 μl. The results determined by HPLC and potentiometric titration were compared. RESULTS:The linear range of ornithine aspartate was 0.02-10.01 mg/ml(r=0.999 9);RSDs of precision,stabili-ty and reproducibility tests were lower than 2%;recovery was 99.15%-100.15%(RSD=0.35%,n=9). The content of 3 batches of Ornithine aspartate for injection was 100.04%-100.64% and molar ratio was 0.982-0.989. The content is similar to the results de-termined by potentiometric titration with national standards. CONCLUSIONS:The method is simple,accurate,specific and sensi-tive,and suitable for the determination of the content and molar ratio of Ornithine aspartate for injection.

[Objective] To explore the relationship between neuroendocrine changes caused by melatonin (MT) hypo-secretion and kidney-in deficiency syvndrome during prepubescence. [Methods] Thirty SD rats after ablactation were randomly divided into normalgroup (group. A), model group (group B) and herbal medicine group (group C, treated with kidney-yin-nourishing ande(?)ficiency-fire-clearing herbs). Rats in groups B and C were exposed to light continuously for 30 days and simultaneously groupC was given kidney-yin-nourishing and deficiency-fire-clearing herbal medicine (13.3 g?kg-1?d-1, qd) for 30 days . After treatment, blood samples were collected at 0:00-2:00 o'clock to observe the changes of blood MT, testosterone (T), epinephrine (E) and norepinephrine (NE) levels. [Results] Body weight and blood MT level decreased, and T, NE and E levels increased in group A (P

Objective To compare the effect of transthoracic contrast echocardiography (cTTE) with transesophageal contrast echocardiography (cTEE) for detecting right to left shunt (RLS) in patients with patent foramen ovale (PFO). Methods The prospective study was conducted in 29 consecutive patients with PFO who suffered from cryptogenic stroke and/or migraine. Contrast echocardiography was performed in all 29 patients. The cTTE was performed using transducer with second harmonic imaging modality (transmitting frequency 1.7 MHz, receiving frequency 3.4 MHz). The cTEE was performed using transducer with frequency 7 MHz. Ten milliliter saline solution of contrast were rapidly administrated through an antecubital vein. According to whether microbubble (MB) appearing in left atrium after complete opaciifcation of right atrium within the ifrst 3 circles, the results were classiifed by a four-level semi-quantitative categorization:Level 1 (no PFO-RSL), no MB in left atrium; Level 2 (small PFO-RSL) 1-10 MBs; Level 3 (medium PFO-RSL) 10-30 MBs;Level 4 (large PFO-RSL)>30 MBs. Results The total detection rate of PFO-RSL was signiifcant different between cTTE and cTEE (86.2%vs 55.2%,χ2=5.711, P=0.017). In cTTE there were 4 cases at level 1, 1 case at level 2, 5 cases at level 3 and 19 cases at level 4. In cTEE there were 13 cases at leverl 1, 2 cases at level 2, 6 cases at level 3 and 7 cases at level 4. The comparison of semi-quantitative grading derived from cTTE and cTEE was also signiifcant different (Wilcoxon signed ranks test showed Z=-3.789, P=0.000). Conclusions The efifciency in detection of PFO-RLS with cTTE was better than with cTEE. Compared with cTEE, cTTE was easier in practice and brought less discomfort and complications to patients.

Objective To evaluate the curative effects of percutaneous osteoperiosteal decortication combined with distraction osteogenesis for treatment of nonunion of lower-extremity bones.Methods A retrospective analysis was performed of the 32 patients who had been treated using osteoperiosteal decortication combined with distraction osteogenesis from September 2011 to December 2014 for nonunion of lower-extremity fractures.They were 23 males and 9 females,with a mean age of 33.4 years (range,from 15 to 62 years).After their former internal or external fixators were removed,the 2 fracture ends were fixated by a retractile mono-lateral or circular external fixator.Under radiographic monitoring,a percutaneous incision was made with a 5 mm sharp chisel,down to the bone.Scar and ossified tissue between the fracture ends were debrided and cut along the fracture line.Mter the marrow cavity was reamed,a new irregular wound was created at sclerotic fracture ends.Scale-shaped chips (1 mm thin and 5 mm in diameter) were elevated using a chisel on surface of the cortical bone within 2 cm from the fracture ends.The external fixators were adjusted to compress the fracture sites.On the 8th day after operation,the eternal fixators were applied to distract and compress at nonunion sites to stimulate the osteogenesis.Results All the patients were followed up for an average of 12.5 months (range,from 8 to 42 months).Primary union was successfully achieved in 28 patients while delayed union occurred in 3 patients who finally achieved union after adjuvant therapies like shock wave and or local injection of bone marrow blood.The average time for union was 4.6 months(range,from 4 to 7 months).The mean time for external fixation was 6.2 months (range,from 5 to 8 months).One patient encountered nonunion of lateral tibial cortical bone 6 months after surgery but eventually achieved union by autologous ilium grafting.Joint functions in all postoperative patients were similar to those before operation.Conclusion Percutaneous osteoperiosteal decortication combined with distraction osteogenesis is a simple,minimally invasive and effective treatment for nonunion of lower-extremity bones,avoiding disadvantages brought by traditional surgery,like massive trauma and excessive bleeding.

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.
