OBJECTIVETo bring forward a method to improve the prominence of the forehead contour.

METHODS16 patients(age 29-53 years, female 11, male 5) were treated through a bicoronal incision. Following the incision, the forehead soft tissues are reflected down to the level of the superior orbital rims with the protection to the supraorbital neurovascular bundles. To adjust the forehead contour, both superior orbital rims and frontal bossing was reduced by burring down the excess bone or removing the anterior wall of the forehead.

RESULTSThe operative effect were satisfactory during 3-12 months of follow-up. No recurrence or osteogenesis were found in the cases. Nasofrontal angle and forehead angle were normal. The prominence of the supraorbital ridges disappeared and forehead became nature.

CONCLUSIONCranioplasty via an osteomy or burring of the outer line of forehead bone are safe, compact and effective way to improve the prominence of the superior orbital rims or frontal bossing.

OBJECTIVETo study the effects of exogenous ER beta on the growth of breast cancer MCF-7 cells under different treatment.

METHODSAn eukaryotic expression vector containing 1.6 kb of human entire coding sequence of ER beta (pCDNA3-ER beta) was transfected into human breast cancer MCF-7 cells using lipofectamine 2000. The biological activity of ER beta was detected with the luciferase reporter containing estrogen responsive element (ERE) and the expression of ER beta protein by Western blot. The growth properties of MCF-7, pCDNA 3-transfected MCF-7 and pCDNA 3-ER beta-transfected MCF-7 cells under different treatment, including E2 (17beta-estradiol) and 4-OHT (4-hydroxytamoxifen), were observed.

RESULTSA stronger activation of the reporter by ER beta in the presence of E2 was observed in the pCDNA 3-ER beta-transfected MCF-7 cells than in the pCDNA 3-transfected MCF-7 and in MCF-7 cells. Western blot analysis showed that the protein level of ER beta in the pCDNA 3-ER beta-transfected MCF-7 cells was markedly increased. Exogenous ER beta expression did not change the growth properties and the morphology of MCF-7 cells under normal condition. The pCDNA 3-ER beta-transfected MCF-7 cells proliferated at the same rate as naive cells in the presence of 4-OHT, whereas a strong inhibition of the proliferation of the pCDNA 3-ER beta-transfected MCF-7 cells in the presence of E2 was observed.

CONCLUSIONExogenous ER beta expression does not increase the resistance to 4-OHT, and a strong inhibition of the proliferation may occur in the presence of E2.

OBJECTIVESTo evaluate if the humoral immune response of hepatitis B DNA vaccine pVAX1-S2S could be enhanced by Talpha1 and/or IFNa expression plasmid co-inoculated.

METHODSThe following mammalian expression recombinant plasmids were constructed: the plasmid pVAX1-S2S expressing hepatitis B surface antigen S2S, the plasmid pVAX1-T/I co-expressing thymosin a and IFNalpha, the plasmid pVAX1-I/S2S co-expressing IFNalpha and S2S. These plasmids were inoculated intramuscularly into several BALB/c mice groups in different combinations. In the co-immunization group 1 (pVAX1-I/S2S), each mouse was inoculated with 100 microg of pVAX1-I/S2S; in the co-immunization group 2 (pVAX1-S2S) each mouse was co-inoculated with pVAX1-S2S and 50 microg of pVAX1-TI; in the control group each mouse was inoculated with 100 microg of pVAX1-S2S. All the immunizations were boosted at 2 and 4 week intervals; then the serum samples were collected to detect the anti-HBs and anti-preS2 strengths.

RESULTS3, 5 and 8 weeks after the first inoculation, the positive rates of anti-HBs were 12.5%, 12.5%, 62.5% respectively in the co-immunization group 1 and 25%, 50%, 50% in the co-immunization group 2, while those in the control group were 0, 25%, 37.5%. The titers of anti-preS2 in co-immunization group 2 was 5 times higher than those in the other two groups.

CONCLUSIONThe data shows that Talpha1 and/or IFNalpha expression plasmid co-inoculated with pVAX1-S2S might act as an adjuvant to enhance the humoral immune response induced by pVAX1-S2S.

OBJECTIVETo evaluate the relation of dose intensity and efficacy, toxicity in advanced breast cancer treated with paclitaxel as a single agent.

METHODSSeventy-one patients with advanced breast cancer received paclitaxel as a single agent with different dose intensities. According to the phase I or phase II trial, the standard dose intensity of paclitaxel was defined as 58.3 mg.(m(2))(-1).week(-1). The dose of paclitaxel was 175 mg/m(2) given every three weeks, ranging 33.3 - 70.3 mg.(m(2))(-1).week(-1) [median delivered dose intensity 58.82 mg.(m(2))(-1).week(-1)]. Efficacy and toxicity was evaluated.

RESULTSThe overall response rate in this group of advanced breast cancer was 40.8%. Responses were seen in lungs, soft tissue, bone and liver, with the response rates of 52.0%, 38.0%, 12.5%, 7.7%, respectively. When the relative dose intensity (RDI) was > 1.0, 0.9 - 1.0, < 0.9, the response rates were 44.2%, 47.6%, 0, respectively. The difference between the group (RDI >/= 0.9% - 1.0%) in 7 patients and the group (RDI < 0.9) was significant (P < 0.05). Toxicity was well tolerated, with the efficacy decreased as soon as the RDI had been reduced without embarrassing the toxicity.

CONCLUSIONPaclitaxel as a single agent therapy with standard dose intensity is effective and well tolerated by patients with advanced breast cancer.

OBJECTIVETo summarize the clinical changing characters of the clinical markers after interferon treatment in chronic hepatitis B (CHB) and make out practical indexes to predict the effect.

METHODS150 CHB patients were randomly divided into two groups: therapeutic group (90) and control group (60) in the prospective controlled trial. The levels of endogenous interferon before treatment, interferon antibody at the end of the second month and fourth month after treatment, alanine aminotransferase (ALT) and HBV DNA in the serum were detected. Then the data was analysed to find out indexes for predicting the effect.

RESULTS(1) The clearance rate of HBeAg had no significant difference in age except for 20 - 30 and 30 - 40 (t > 2.331 2, P < 0.01). (2) It was more effective if ALT level was higher than 400 U/L before treatment and it decreased more than 50% two months after treatment. (3) The patients whose HBV DNA was negative (dot hybridization) or less than 10(6) copies/ml before treatment had higher rate of HBeAg clearance. (4) There was no effect on patients whose interferon antibody turned positive at the end of the second month. (5)A predictive method of comprehensive factors was made out, whose sensitivity, specificity, and accuracy were 80%, 100% and 90%, respectively.

CONCLUSIONThe clinical characters of these Chinese patients are different from those of the westerners and the effects of interferon have close relation to the levels of ALT, HBV DNA and interferon antibody.

PURPOSE: Human papillomavirus (HPV) infection is a well-known cause of cervical cancer, which, along with its precursors, can be diagnosed and treated with cervical conization (CC). This study aimed to assess HPV- and procedure-related knowledge among women who had undergone CC. MATERIALS AND METHODS: Between February and May 2014, consecutive women who had undergone CC at five different educational hospitals were recruited. All patients had undergone a loop electrosurgical excision procedure as the method of CC. A survey was conducted with a self-developed, 29-item questionnaire, measuring knowledge related to HPV and CC. We analyzed the responses of 160 patients who completed the questionnaire. RESULTS: Mean total knowledge scores (±standard deviation) for HPV and CC were 5.2±3.0 of a possible 13.0 and 8.3±4.2 of a possible 16.0, respectively. While 73% of the patients knew that HPV is the main cause of cervical cancer, only 44% knew that HPV is sexually transmitted. The purpose of CC was correctly identified by 71% of the patients. However, 35% failed to indicate the anatomical area resected at the time of CC in the schematic diagram. Women who were younger (p<0.001), had higher education level (p<0.001), and higher family income (p=0.008) had higher knowledge scores. In contrast, neither interval from CC to survey nor disease severity were associated with total knowledge score. CONCLUSION: The level of knowledge related to HPV and CC was unexpectedly low in women who had undergone CC. Intuitive educational resources may improve this knowledge, and further cohort studies are warranted.

OBJECTIVESTo compare the sensitivity of mammogram and breast dedicated MRI in detecting ductal carcinoma in situ with microinvaion (DCIS-MI) and ductal carcinoma in situ (DCIS) lesions, and to further investigate the independent predictive factors of mammogram and MRI sensitivity.

METHODSFrom August 2009 to November 2011, 122 consecutive confirmed breast cancer patients who had received operations were recruited for this clinical research. These patients were divided into two groups including DCIS (72 cases) and DCIS-MI (50 cases) based on pathologic reports. All the patients were female, with mean ages of 52.6 years and 54.4 years. Preoperative bilateral breast mammogram, breast dedicated MRI depictions and reports as well as histopathological reports were collected.

RESULTSSensitivity of MRI outstood mammogram in each subgroups: 84.7% vs. 42.4% in DCIS (χ(2) = 27.028, P = 0.000), 94.0% vs. 80.0% in DCIS-MI group (χ(2) = 4.540, P = 0.040). And further analysis showed that MRI was more sensitive to high nuclear grade DCIS and DCIS-MI lesions than low nuclear grade ones (OR = 3.471, P = 0.031).

RESULTSof logistic regression analysis proved microcalcification was an independent predictive factor of mammogram sensitivity (OR = 11.287, P = 0.001).

CONCLUSIONSSensitivity of breast dedicated MRI is superior to mammogram in detecting DCIS and DCIS-MI groups. Lesions with microcalcifiation is an independent predictive marker which meant that mammogram would achieve high detection rate in cancers presented calcification on mammogram image when compared with non-calcification. Diagnostic performance of breast MRI is less affected by clinical and pathological characteristics of the early stage breast cancer patients but further increased detection rate is observed in DCIS and DCIS-MI with high nuclear grade lesions which indicated that MRI could detect more early stage cancers with relative more aggression biological behaviour and provide these patients with early surgical interventions before possible progression to invasive breast cancers.

OBJECTIVETo investigate the long-term clinical efficacy and adverse effects of botulinum toxin-A (BTX-A) injection in the treatment of gastrocnemius spasticity in children aged 9-36 months with cerebral palsy.

METHODSEighty children aged 9-36 months with cerebral palsy and gastrocnemius spasticity were selected and randomly divided into a BTX-A injection group and a conventional treatment group (n=40 each). The children in the BTX-A injection group received injections of BTX-A guided by color Doppler ultrasound and 4 courses of rehabilitation training after injection. Those in the conventional treatment group received 4 courses of the same rehabilitation training alone. Before treatment and at 1, 2, 3, and 6 months after treatment, the modified Tardieu scale (MTS) was applied to assess the degree of gastrocnemius spasticity, the values in the passive state measured by surface electromyography (sEMG) were applied to evaluate muscle tension, and the Gross Motor Function Measure (GMFM) was used to evaluate gross motor function.

RESULTSCompared with the conventional treatment group, the BTX-A injection group had significantly greater reductions in MTS score and the values in the passive state measured by sEMG (P<0.05), as well as significantly greater increases in joint angles R1 and R2 in MTS and gross motor score in GMFM (P<0.05). No serious adverse reactions related to BTX-A injection were found.

CONCLUSIONSBTX-A injection is effective and safe in the treatment of gastrocnemius spasticity in children aged 9-36 months with cerebral palsy.

Background: and Purpose Nelonemdaz (Neu2000) has both selective antagonism against 2B subunit of N-methyl-D-aspartate receptor and antioxidant activity. This drug provides sufficient evidence of neuroprotection in acute cerebral ischemia/reperfusion models. This phase III trial aims to determine this effect in patients.Design The Rescue on Reperfusion Damage in Cerebral Infarction by Nelonemdaz is a multicenter, double-blinded clinical trial. A total of 496 patients will be randomly assigned into the nelonemdaz (a total of 5,250 mg divided by 10 times for 5 days) and placebo groups. Patients will be included if they have an acute ischemic stroke (National Institutes of Health Stroke Scale score ≥8) caused by intracranial large vessel occlusion in the anterior circulation (Alberta Stroke Program Early CT Score ≥4), and if they are expected to undergo endovascular thrombectomy within 12 hours after stroke onset.Endpoints The primary endpoint is a favorable shift in the modified Rankin Scale (mRS) score at 90 days after the first dose of drug. The data will be analyzed by the Cochran–Mantel–Haenszel shift test. The secondary endpoints include functional independence (mRS 0–2) at 35 and 90 days, the favorable shift of mRS at 35 days, the proportion of mRS 0 at 35 and 90 days, and the occurrence rates of symptomatic intracranial hemorrhage within 7 days. Conclusion This trial will clarify the efficacy and safety of nelonemdaz in patients with acute ischemic stroke and endovascular thrombectomy. This study has been registered at ClinicalTrials. gov (NCT05041010).
