Objective To evaluate the method for vaginal treconstruction with muscle sparing verti-cle rectus abdominis myocutaneous flap(MS-VRAM flap). Methods From September 2006 to April 2008, MS-VRAM flaps were used for vaginal reconstruction in 9 patients (20 to 35 years old), ancl all ca-ses were congenital absence of vagina. Before operation, the inferior epigastrie arteries were detected by the Doppler and the flaps based on the perforators ranged from 6 cm×20 cm. MS-VRAM flaps were ele-vated and then transferred to reconstruct the vagina. Results All 9 cases of MS-VRAM flaps survived completely. No complications occurred at donor site of abdominal wall. With 2-12 months' follow-up, the patients were satisfied with the results. Conclusion Despite technical difficulties in elevating the MS-VRAM flap, the flap is a good choice for vaginal reconstruction.

BACKGROUND: Essential tremor is a kind of dyskinesia disease with a tendency to heredity. β-adnephrin receptor blocker is mainly used for treatment, but the dosage was great, patients could not persist in treatment. Hydrochloric-acid arotinolol, which characterizes by little side effect, is a β-receptor blocking agent combined with blocking effect of α receptor, and is an ideal drug to treat essential tremor in Japan.OBJECTIVE: To observe the reliability and curative effect of hydrochloric-acid arotinolol on essential tremor among Chinese people.DESIGN: Case analysis.SETTING: Neurological Departments of Beijing Hospital of Ministry of Public Health and General Hospital of Beijing Military Area Command of Chinese PLA.PARTICIPANTS: Totally 30 patients with essential tremor, 19 males and 11 females, aged from 21 to 74 years, with course of 1-40 years, average of (15.8±12.6) years, were selected from Neurological Departments of Beijing Hospital of Ministry of Public Health and General Hospital of Beijing Military Area Command of Chinese PLA from April 1999 to December 2000.METHODS: Tremor degree of upper limb, caput and lower limb, degree of dysfunction of hand, tremor degree of hand during writing and circling, and chief complaint of pain caused by tremor were scored before medication and 2, 4 and 6 weeks after medication. Scores were determined as 1 point, 2 points and 3 points according to mild, moderate and severe degree respectively. Evaluated criteria: ① Obviously effective: Differences were more than 7 points before and after treatment. ② Effective: Differences were 6.5-3 points before and after treatment. ③ A little effective: Differences were 3-1.5 points before and after treatment. ④ No changes: Differences were from 1 to -1 points before and after treatment. ⑤ Worse: Differences were less than -1.5 points before and after treatment. Meanwhile, blood pressure and heart rate of patients and side effect of drug were observed.MAIN OUTCOME MEASURES: ① Results of effective evaluation; ②Blood pressure and heart rate before and after treatment; ③ Adverse events and side effect.RESULTS: Totally 30 patients entered the final analysis. ① Among 30 patients with essential tremor, 6 had obvious effect, 11 had effect, 5 had a little effect, 7 had no effect, and 1 was worse. ② Average of blood pressure before treatment was (138.5±14.6)/(84.2±6.4) mm Hg (1 mm Hg=0.133 kPa), and was (130±10)/(79.7±6.3) mm Hg after 1 course. Average heart rate was (77.5±6.4) times/minute before treatment and (75±6.4) times/minute after treatment. The difference was not significant. ③ Among 30 patients, 4 had side effect at various degrees which was accounted for 13.4%; 1 had distress after medication, 1 had agrypnia, 2 had fullness in head and dizziness, and 1 gave up the treatment because of deteriorated tremor.CONCLUSION: Hydrochloric-acid arotinolol can improve tremor symptom of patients obviously and is an effective drug to treat essential tremor with convenient and safe medication.

OBJECTIVE:To optimize the extraction technology of chlorogenic acid in Prunus armeniaca flos,and compare the contents in P. armeniaca flos from different origins and varieties. METHODS:HPLC was conducted to determine the content of chlorogenic acid in P. armeniaca flos;using the volume fraction of ethanol,the ratio of material to liquid,ultrasonic extraction times and time as factor,the content of chlorogenic acid as index,single factor and orthogonal test were designed to optimize the extraction technology,and verification tests were carried out. The optimized extraction technology was used to extract and compare the contents of chlorogenic acid in Armeniaca sibirica from 7 origins of P. armeniaca flos and 3 origins of Armeniaca sibirica flos. RESULTS:The optimized extraction technology was extracting twice with 12-fold 75% ethanol,30 min each time. Under the con-ditions,the content of chlorogenic acid can reach 77.38 mg/g(RSD=0.58%,n=3);the contents of chlorogenic acid in A. sibiri-ca flos and P. armeniaca flos were 77.38-83.33 mg/g and 63.12-70.22 mg/g,respectively. CONCLUSIONS:The established extrac-tion technology is reasonable,stable and feasible. The contents of chlorogenic acid in A. sibirica are higher than that in P. armenia-ca flos;the contents have no obvious differences in the same variety of A. sibirica from different origins.

Objective To analyze the relationship between central lymph node metastasis and clinical features of papillary thyroid microcarcinoma. Methods From January 2010 to October 2016, 137 patients were treated with papillary thyroid microcarcinoma and central lymph node dissection. Among them, 35 were male and 102 were female. There were 49 cases with age ≤ 45 years old, 88 cases > 45 years old. 36 cases had diameter of tumor≤5 mm, 101 cases>5 mm; There were 72 cases with tumor fibrosis, 65 cases without fibrosis; 22 cases with psammoma bodies, 115 cases without psammoma bodies. There were 16 cases with tumor associated with chronic lymphocytic thyroiditis, 121 cases without them. The clinical factors affecting lymph node metastasis in the central group were analyzed byχ2 test. Results Of the 137 patients, 52 cases (38.0%) had central lymph node metastasis. Age, tumor diameter, fibrosis, psammoma bodies had relationship with central lymph node metastasis (χ2 values were 4.48, 5.60, 7.30, 7.30, all P<0.05). Sex, tumor associated with chronic lymphocytic thyroiditis had no relationship with central lymph node metastasis (all P> 0.05). Conclusion The papillary thyroid microcarcinoma patients with age≤45 years old, tumor diameter>5 mm, fibrosis in the tumor area and psammoma bodies have high risk of lymph node metastasis.

Objective To investigate whether lipopolysaccharide (LPS) can induce vascular endothelial cell growth factor (VEGF) expression in microglia regulated by hypoxia inducible factor-1α(HIF-1α). Methods The cultured BV2 cells were divided into four groups:control group, LPS (100 μg/L) simulated group, LPS (100 μg/L)+LPS antagonist (LRS, 200 μg/L) intervened group and LPS (100 μg/L)+HIF-1αinhibitors FM19G11 (10 mmol/L) intervened group. Immunofluorescence staining, Western blotting and ELISA were used to detect the expressions of VEGF and HIF-1α. Results Compared with the control group, the VEGF expression level was obvious high in LPS simulated group (P<0.05). LRS inhibited this effect of LPS (P<0.05). The HIF-1αlevel was increased in LPS simulated group at 8 h post-injury (P<0.05). FM19G11, the inhibitor of HIF-1αreduced the expression of VEGF induced by LPS (P<0.05). Conclusion LPS can up-regulate the expression of VEGF by HIF-1α.
