Objective To examine serum TFAR19 activity in uterine myoma patients.Methods 45 of operation patients with uterine myoma in Beijing Huairou Maternal and Child Health Hospital were recruited.Among them,diameter of maximal myoma from 6 to 10 centineters were 29 (group A),diameter of maximal myoma more than 10 centineters were 16 (group B).In addition,25 unrelated healthy women of childbearing age from physical examination center were enrolled as controls (group C),all of the peripheral venous blood was collected after admission.Enzyme-linked immunosorbent assay (ELISA) was used to examine serum TFAR1 9 activity in uterine myoma patients.Results The activity of TFAR1 9 in group A,group B and group C were 25.32±1.93,14.41±2.28 and 34.79±4.65 respectively.The TFAR19 activity in each group was sta-tistically significant difference (F=7.93,P=0.01).Compared with group C,the TFAR19 activity in group B (q=5.606,P<0.001),group A (q=3.055,P=0.034)was statistically significant difference.The TFAR19 activity in uterine myoma patients subgroups (group A,group B)was statistically significant difference (q=3.086,P=0.033).Age between each groups was not statistically significant difference (F=2.086,P=0.132).Conclusion The decrease of TFAR19 can inhibit apoptosis.Participating the occurrence of uterine myoma,it is connected with diameter of myoma.The larger diameter of my-oma,the lower TFAR1 9 activity of examination will be.

OBJECTIVE: To investigate the protective effects of Lycium barbarum polysaccharide(LBP) against injury from oxygen-glucose deprivation/reperfusion (OGD/RP) in primary cultured rat hippocampal neurons. METHODS: Cultured hippocampal neurons were exposed to oxygen-glucose deprivation (OGD) for 2 h followed by a 24 h reperfusion. The MTT assay and the lactate dehydrogenase (LDH)release were used to evaluate the protective effects of LBP. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA)were determined by spectrophotometry using commercial kits. Mitochondrial membrane potential (MMP) and the intracellular free calcium concentration ([Ca2+]i) in hippocampal neurons were measured using confocal laser scanning microscope (CLSM). RESULTS: Treatment with LBP (10-40 mg · L-1) significantly attenuated neuronal damage and inhibited LDH release in a dose-dependent manner. Furthermore, LBP enhanced activities of SOD and GSH-Px but it decreased their MDA content, inhibited [Ca2+]i elevation and decrease of MMP in ischemia-reperfusion treated hippocampal neurons. CONCLUSION: These findings suggested that LBP may be a potential neuroprotective agent for cerebral ischemia-reperfusion injury.

Objective To evaluate the curative effect of the atorvastatin calcium tablet(trade name:lipitor) in curing essential hypercholesterolemia.Methods 76 patients with essential hypercholesterolemia were divided into two groups randomly:43 patients in the research group(lipitor tablet 10mg,qn);33 patients in the comparison group (simvastatin tablet 20mg,qn).The period of treatment for both two groups was 6 weeks.The changes of blood fat were detected before and after taking the medicine.The curative effect were compared at the same time.Resnlts The total cholesterol(TC)of the research groups decreased by 37.06%,the TC of the comparison group decreased by 22.05%.The triacylglyceride(TG)of the research group decreased by 24.81%,however,the TG of the compar- ison group decreased by just 14.49%.The low-density lipoprotein cholesterol(LDL-C)of the research group de- creased by 42.30% while the comparison group just decreased by 28.30%(P＜0,01).Also,the high-density lipoprotein cholesterol(HDL-C)of the research group increased by 7.80%,and the comparison group increased by 7.13%(P＞0.05),The effective rate of the research group was 95.35%.For the comparison group,the effective rate was 90.91%.Conclusion The lipitor has a good curative effect in curing essential hypereholesterolemia.Also, the lipitor has fewer side effect,This medicine is safe and reliable for patients.

OBJECTIVETo investigate the application of combining mastopexy and triple-plane breast augmentation in correction of breast ptosis and atrophy.

METHODSPeri-areolar incision was performed to finish the fascia and dermal suspension to correct the breast ptosis. The implant was inserted under the pectoralis major muscle through lateral lower border of the gland and a "X" shape full thickness incision was made on the pectoralis major muscle according to the new position of nipple-areolar complex.

RESULTS14 patients received combined mastopexy and triple-plane breast augmentation to correct breast atrophy and mastopexy simultaneously. All the patients were regularly followed for 6-12 months. No patients suffered severe complication and the results were satisfied.

CONCLUSIONS"Triple-plane" breast augmentation could be safely performed with peri-areolar mastopexy with minor injury. The technique could help to ensure the balance between the gland, nipple-areolar complex and the implant.

Phased national medical licensing examination requires clinical students to have the ability to apply basic medical knowledge to solve comprehensive clinical problems. But the traditional teaching patterns of Medical Microbiology experiments can no longer meet requirements of actual education effect. In order to accommodate new situation, we have integrated medical licensing examination with microbiology experimental teaching syllabus and contents. We have also comprehensively applied a variety of teaching methods and curriculum formative assessment in class. These reforming methods have efficiently improved classroom teaching effect and greatly inspired the enthusiasm of students, and effectively improved early clinical thinking ability and innovation ability of students.

Abstract: Objective To analyze a case of bloodstream infection caused by Ureaplasma urealyticum after abortion in Anxi County Hospital, so as to provide basis for the clinical diagnosis and treatment. Methods　The diagnosis of Ureaplasma urealyticum in this patient with bloodstream infection was retrospectively analyzed. The basic clinical data and laboratory diagnosis data were collected, including the characteristics of blood culture curve, Wright staining of culture medium, drug sensitivity of Mycoplasma liquid identification, colony characteristics of solid medium, and the conclusion of targeted DNA sequencing. Through the comprehensive analysis of the above data, the rapid diagnosis of this case can be realized by optimizing the detection and diagnosis process. Results　The clinical manifestations of this patient were fever of 38.5 ℃, CRP:14.85 mg/L, WBC:14.33×109/L, NET: 85.40%, PCT: 0.12 ng/mL, IL-6: 665.6 pg/mL, positive after 3 days of blood culture, no bacteria were found in Gram stain, and sand-like purple bacteria were observed after adding Wright's stain. After inoculation in blood agar, Mycoplasma solid and liquid medium, no colonies were grown in blood agar, after 48 h and 5 d. On Mycoplasma A7 agar, the edge of brown fried egg colony was striature, and it could be identified as Ureaplasma urealyticum with the Mycoplasma ID & AST panel, which was resistant to quinolones and spectinomycin, but sensitive to macrolides, tetracyclines and lincomycin. Subsequent targeted DNA sequencing results were also confirmed for Ureaplasma urealyticum. Before receiving the report, clinical experience treatment with ceftriaxone metronidazole was used to fight infection with negative bacilli and anaerobic bacteria. Mycoplasma was not treated with targeted treatment. After 3 days, the patient's body temperature returned to normal, inflammation index decreased, and the patient asked to be discharged. Conclusions　At present, there are few reports of bloodstream infection caused by Ureaplasma urealyticum, and the lack of clinical understanding can easily lead to misdiagnosis and missed diagnosis. In order to improve the detection rate of Mycoplasma in blood culture, it is necessary to optimize the detection procedure of blood culture and provide accurate diagnosis and treatment basis for clinical practice. However, it is clear from this case that Mycoplasma bloodstream infection cases are self-limited infection and can recover by themselves without targeted treatment in patients with normal immunity. Therefore, it is very important to protect the immunity of patients.
