ObjectiveTo evaluate the significance of ankler-brachial index (ABI) to predict the extent of intracranial artery stenosis in ischemic stroke patients. Methods243 ischemic stroke patients were enrolled, brain angiography were examined and all of the ABI and basic data were collected. ResultsABI≤0.9 was associated with a specificity of 84.6% and a sensitivity of 16.8% for predicting the presence of severe stenosis in intracranial artery. The area under receiver operating characteristic curve was (0.591±0.046) (P<0.05). ConclusionABI≤0.9 has a relative specificity and sensitivity for predicting the presence of severe stenosis of intracranial artery.

Objeictivie To investigate the diagnostic value of anti-mutated citrullinated vimentin (anti-MCV) antibody, anti-cyclic citrullinated peptide (anti-CCP) antibodies and glucose-6-phospha-teisomerase (GP1) for rheumatoid arthritis (RA). Methods Anti-MCV antibody, GPI and anti-CCP antibody were detected in serum samples of 109 RA patients, 24 non-RA rheumatic diseases patients and 19 healthy blood donors. The sensitivity and specificity of these parameters for the diagnosis of RA were analyzed. Results Both the positive rate and average cut off concentration of anti-MCV and GPI in RA were higher than those of non-RA rheumatic diseases or healthy controls (P<0.05). A significant difference was found between anti-MCV and GPI in RA patients. The most sensitive and specific parameter in RA was anti-MCV (99.1%) and anti-CCP (90.7%) respectively, but, when anti-MCV combined with anti-CCP, or GPI or anti-CCP and GPI, the specificity could be up to 98.1%. Coniclusions Anti-MCV, anti-CCP and GPI alone or in combination may be valuable parameters for the diagnosis of RA.

Objective To evaluate the value of whole genome amplification (WGA) combined with array comparative genomic hybridization (aCGH) in prenatal diagnosis. Methods Array CGH were performed by the DNA of 18 prenatal specimens , which were amplified by WGA because of the low DNA yield. Result 3 of the 18 fetuses were 45, X0 and 9 of 15 fetuses with normal aCGH results showed healthy outcome. Conclusion It’ s feasible for prenatal diagnosis using WGA combined with aCGH which not only can shorten the reporting time but also keep the sensitivity and accuracy of detection.

Objective To observe the effect of catechol-O-methyltransferase inhibitor (COMTI) tolcapone on levodopa-treated patients with Parkinson's disease (PD) and on the motor function fluctuation, and safety taking this drug.Methods50 PD patients treated with levodopa were divided into the trial group and control group with 25 cases in each group. The patients in the trial group were given tolcapone 100 mg three times per day. The cases in the control group were given placebo with the same dose. The hepatic function of the patients was examined every month after administration. The time variety of patients' motor function fluctuation was recorded by the diary. The time of clinical observation was 6 months.ResultsThe UPDRS scores of the trial group in the first and second months after taking tolcapone were not significantly different from that of the control group ( P>0.05), but scores of the third to sixth months were significantly different from that of the control group ( P<0.05~0.01). There was a significant difference between UPDRS scores of the trial group before and after treatment ( P<0.01~0.001). The Honhe-Yahr scores of the trial group in the first and second months after treatment were not significantly different from that before treatment ( P>0.05), but scores of the third to sixth months were significantly different from that before treatment ( P<0.05). The motor function fluctuation of the patients in the trial group improved significantly after treatment ( P<0.05). The numbers of the cases had dry mouth, nausea and astriction were 3 respectively; those had acratia, insomnia and diarrhea were 2 respectively; those had muscular soreness, abdominal distention, hidrosis and fidget were 1 respectively. All adverse effects had a little influence to administration. The hepatic function of all patients had no significant change.ConclusionTolcapone can increase the curative effect of PD patients treated with levodopa and improve the motor function fluctuation, and is safety after taken.

BACKGROUND AND OBJECTIVESerum tumor markers play important roles in diagnosis, response and prognosis monitoring for lung cancer. The clinical significance of serum level of tissue polypeptide specific antigen (TPS) was investigated in diagnosis, response monitoring and prognosis in patients with lung cancer, compared with carcinoembryonic antigen (CEA), precursor of gastrin-releasing peptide (Pro-GRP) and cytokeratin-19-fragments (CYFRA21-1).
METHODSBlood samples of eighty-two patients with lung cancer before treatment and some after chemotherapy were measured by ELISA for four tumor markers.
RESULTSCompared with lung benign diseases group and health control group, the positive rates and levels of TPS, CEA and Pro-GRP in patients with lung cancer were higher, with statistically significant difference. TPS in extensive-small cell lung cancer was significant higher than that in limited-small cell lung cancer. The positive rates and levels of TPS, CEA and Pro-GRP in patients after treatment had significant decreases compared with before treatment. TPS was an independent prognostic factor of non-small cell lung cancer.
CONCLUSIONTPS is valuable to diagnosis, response monitoring for patients with lung cancer, moreover, it maybe a useful factor of prognosis of non-small cell lung cancer.

Purpose:
Seroma formation is a common complication in breast cancer patients undergoing mastectomy, and it negatively affects patient recovery after surgery. The present study aimed to evaluate a simple method using fascia suture technique to fix the flap and reduce the incidence of seroma.
Methods:
A single-center, prospective, randomized controlled trial was carried out among 160 patients who had undergone mastectomy from May 2018 to September 2019. All patients were randomly divided into the fascia suture group (n = 80) or control group (n = 80) and were followed up for at least 3 months for the assessment of immediate and late complications after surgery.
Results:
No significant differences were observed between the 2 groups with regard to the basic characteristics. Duration of surgery in the fascia suture group was longer by about 6 minutes compared with that in the control group (114.93 ± 13.67 minutes vs. 108.81 ± 15.20 minutes, p = 0.008). The fascia suture group had a shorter duration of drain placement (10.99 ± 3.26 days vs. 13.85 ± 5.37 days, p < 0.001), a smaller volume of the total drainage (460.95 ± 242.92 mL vs. 574.83 ± 285.23 mL, p = 0.007), and the first 3-day drainage (224.96 ± 101.01 mL vs. 272.3 ± 115.47 mL, p = 0.006), compared with the control group. The incidence of seroma formation (G2 or G3) was significantly lower in the fascia suture group compared with the control group (28.8% vs. 12.5%, p = 0.033). Besides, there was no statistical difference between the 2 groups in the assessment of other complications, including postoperative pain, hematoma, surgical site infections, flap necrosis, and skin dimpling (all p > 0.050).
Conclusion
The fascia suture technique is a simple and effective method for reducing seroma formation and should be used to prevent seroma formation after mastectomy.
