ABSTRACT
Objective:To evaluate the efficacy of monopolar radiofrequency combined with ultrasound for abdominal obesity.Methods:A total of 24 patients (4 males, 20 females, average age was 35 years) were given monopolar radiofrequency combined with ultrasound treatment four times at (10±4) day interval at Beijing Friendship Hospital during December 2015 to December 2016. Body weight and abdomen circumferences were recorded before and after each treatment. Subcutaneous adipose tissue thickness was measured with B ultrasound at baseline and after the last treatment. 2 months after the last treatment, a third party would assess the improvement; at the same time, volunteers would assess the outcome with Global Aesthetic International Scale. Blood lipid level, liver function and renal function were tested at baseline and after the third treatment. All the treatment related adverse effect would be noted as well.Results:There was no significant difference of body weight after the treatment. The abdomen circumferences were decreased at 2 month after the last treatment, especially for the navel one, which decreased from (96.14±11.92) cm at baseline to (93.82±10.77) cm, t=4.21, P<0.05. And the subcutaneous adipose tissue thickness also decreased from (25.56±4.3) mm to (24.31±3.77) mm, ( t=6.26, P<0.05). 2 months after the last treatment, 16 volunteers were graded as 1-25% improvement, 8 volunteers were graded as 26%-50% improvement. According to GAIS, 2, 18 and 4 volunteers assess the outcome was regarded as 0 score, 1 score and 2 score respectively. The treatments showed no influence to blood lipid level, liver function and renal function. The treatment processing was tolerated well and no side effect were noted. Conclusions:Monopolar radiofrequency combined with ultrasound treatment for abdominal obesity is effective and safe.
ABSTRACT
Objective:To investigate the short-term efficacy and safety of albumin-bound paclitaxel combined with nedaplatin followed by concurrent radiotherapy in treatment of stage Ⅲ massive cervical cancer.Methods:The clinical data of 84 patients with massive cervical cancer admitted to Harbin Medical University Cancer Hospital from April 2019 to April 2020 were retrospectively analyzed. According to the different treatment regimens, patients were divided into the observation group and the control group, each with 42 cases. The observation group received albumin-bound paclitaxel combined with nedaplatin followed by concurrent radiotherapy, and the control group received solvent-based paclitaxel combined with nedaplatin followed by concurrent radiotherapy. The short-term efficacy and adverse reactions of the two groups were compared.Results:The partial remission (PR) rate of the observation group and the control group at 1 month of treatment was 92.9% (39/42) and 35.7% (15/42), respectively, and the difference was statistically significant ( χ2 = 29.867, P < 0.01). The complete remission (CR) rate of the observation group and the control group at 1 month after treatment was 59.5% (25/42) and 38.1% (16/42), respectively, and the difference was statistically significant ( χ2 = 3.859, P = 0.049). The incidence of diarrhea of the observation group was lower than that of the control group [33.33% (14/42) vs. 54.8% (23/42)], and the difference was statistically significant ( χ2 = 3.913, P = 0.048). There were no statistical differences in the incidence of hematological adverse reactions and abnormal liver and kidney functions between the two groups (all P > 0.05). Conclusion:The albumin-bound paclitaxel combined with nedaplatin followed by concurrent radiotherapy have a good short-term efficacy in treatment of stage Ⅲ massive cervical cancer, and the adverse reactions are tolerable.
ABSTRACT
Objective:To study the clinical effect of alpha hydroxy acids on facial acne patients.Methods:A total of 36 patients with facial acne who were treated at the Department of Dermatology, Beijing Friendship Hospital from December 1, 2018 to May 31, 2019 were selected. All patients were treated with 20% alpha hydroxy acids. Treatment efficiency, lesions improvement and patients＇satisfaction were evaluated.Results:All evaluation indexes were improved after treatment. Before treatment, patients with acne were classified into grade Ⅰ(9 cases), grade Ⅱ(18 cases ), and grade Ⅲ (9 cases) through Pillsbury Grading, and after treatment, there were 28 cases of grade Ⅰ, 28 cases of grade Ⅱ, and 0 cases of grade Ⅲ, which had statistic differences ( χ2= 22.603, P<0.001). The number of lesions before treatment was 38.64±15.57, and that was 16.17±11.49 after treatment, and the difference was statistically significant ( t=6.967, P<0.001). After treatment, 2 cases were cured, 17 cases were markedly effective, 11 cases were effective, 2 cases were ineffective and 4 cases were worsening. 30 patients were cured, markedly effective or effective, and the total effective rate was 83.33%. The value of skin pores before treatment was 1263.67±593.44, and decreased to 1196.33±579.27 after treatment. The difference was statistically significant ( t=3.155, P<0.05). After the treatment, all the patients were satisfied with the effect. Conclusions:Alpha hydroxy acid is a safe and effective method for acne patients.
ABSTRACT
Objective:To investigate the correlation of sleep disorders(SD)with serum levels of amyloid β-proteins(Aβ 1-42)and tau phosphorylated at threonine(P-Tau 181)in patients with Alzheimer's disease(AD). Methods:A total of 126 patients with mild and moderate AD who met the inclusion criteria in the memory clinic, sleep clinic and geriatrics department of Jianghan Oilfield General Hospital affiliated to Yangtze University from February 2017 to January 2020 were included.The Pittsburgh Sleep Quality Index(PSQI)was used to evaluate sleep quality.Patients with PSQI scores ≥7 were included in the AD group with sleep disorders(AD-SD group), and patients with PSQI scores <7 were included in the AD group without sleep disorders(AD-NSD group). The Montreal Cognitive Assessment(MoCA), Global Deterioration Scale(GDS), Clinical Dementia Rating(CDR), Hamilton Rating Scale for Depression(HRSD)and Hamilton Anxiety Rating Scale(HAM-A)were used to evaluate cognitive and psychosocial symptoms.During the same time, biological markers such as serum Aβ 1-42, Aβ 1-40 and P-Tau 181 were detected by using enzyme-linked immunosorbent assays.Patients in the two groups received donepezil as an anti-dementia therapy, while the AD-SD group was treated additionally with a targeted sleep intervention.All patients underwent neuropsychological assessment and biochemical tests at enrollment and at the end of the 6th month, and results from all parameters at baseline and at the end of the 6th month were compared.At the end of the six-month treatment, patients in the AD-SD group were further divided into the recovery AD-SD sub-group and the no-recovery AD-SD sub-group based on the extent of sleep improvement. Results:Of the 126 AD patients, 93(73.8%)had sleep disorders.There was no statistically significant difference between the two groups in gender, age, onset age, educational level, course of disease, CDR, GDS, MoCA, Aβ 1-40 or Aβ 1-42/Aβ 1-40(all P>0.05). The scores of PSQI, HRSD and HAM-A and serum levels of Aβ 1-42 and p-Tau 181 showed statistically significant differences between the AD-ND and AD-NSD groups( P<0.05 or P<0.01). At the end of the 6th month, the scores of PSQI, GDS, HRSD and HAM-A and levels of Aβ 1-42, Aβ 1-40, and P-Tau 181 also showed statistically significant differences between the AD-ND and AD-NSD groups( P<0.05 or P<0.01). There was no statistically significant difference in results from other parameters( P>0.05). Spearman correlation analysis showed that PSQI was correlated with HRSD( r=0.271, P=0.009), HAM-A( r=0.479, P=0.000), Aβ 1-42( r=0.470, P=0.000), Aβ 1-42/ Aβ 1-40( r=0.479, P=0.000)and P-Tau 181( r=0.371, P=0.000)in the AD-SD group at baseline.Multivariate Logistic regression model showed that serum Aβ 1-42 and P-Tau 181 levels and HRSD had predictive effects on changes in sleep quality in AD patients( OR=1.897, 1.269 and 1.889, P=0.000, 0.003 and 0.000). The areas under the receiver operating characteristic(ROC)curves for Aβ 1-42, P-Tau 181 and HRSD were 0.926(95% CI: 0.860-0.991), 0.837(95% CI: 0.746-0.927)and 0.854(95% CI: 0.776-0.932), respectively. Conclusions:Sleep quality is correlated with serum Aβ 1-42and P-Tau 181 levels in AD patients.Elevated serum levels of Aβ 1-42 and P-Tau 181 and high HRSD scores are important predictors of SD in AD patients and may be used as indexes for clinical treatment efficacy.
ABSTRACT
Objective@#To understand neglect and its associated factors among migrant middle school students in Tianjin, and to help them develop physically and mentally.@*Methods@#A survey of 3 666 middle school students in 10 middle schools located in migrant gathering regions was conducted. Neglect and associated factors were collected and compared between migrant and non-migrant students.@*Results@#The neglect rate of migrant middle school students in Tianjin was 45.79% and that of non-migrant students was 31.37%, the difference was statistically significant (χ2=56.25, P<0.01). The total neglect of middle school students who moved with them was (52.46±8.12) points; the neglect of boys, junior high schools, non-only children, fathers and mothers with high school education and below were significantly higher than those of girls, high schools, single children, and parents with high school education (t=3.73, 10.40, -11.36, 13.81, 15.57, P<0.01). The longer the follow-up period and the lower the family income, the higher the degree of neglect among the middle school students, and the difference was statistically significant (F=89.27, 53.48, P<0.01). Regression analysis showed that the following time (OR=3.55), whether the only child (OR=4.19) showed a positive correlation with the neglect of middle school students; family income (OR=0.71), parental education (OR=0.48, 0.25) were negatively correleted with neglect (P<0.05).@*Conclusion@#The neglect of middle school students in Tianjin is serious. The time of family migration, family income and parental education are important factors affecting neglect.

ABSTRACT
Objective To analyze the short-term complications and long-term outcomes of spleenpreserving distal pancreatectomy (SPDP) in pediatric pancreatic tumors.Methods A retrospective analysis was conducted on 43 patients with tumors of the body and tail of the pancreas in Beijing Children's Hospital from Jan 2007 to Jan 2018.Results There were 17 boys (39.53％) and26girls (60.47％),with a median age of 123 (80,141) months.The median maximum diameter of primary tumor was 7.60 cm.Diagnoses included solid pseudopapillary tumor (n =28),pancreatoblastoma (n =10),neuroendocrine tumor (n =4),and pancreatic cyst (n =1).Two cases (4.65％) received tumor enucleation,4 cases (9.30％) did distal pancreatectomy plus splenectomy,and 37 cases (86.05％) did SPDP.16 cases (37.21％) had short-term complications,including pancreatic fistula (n =13),delayed gastric emptying (n =3),abdominal infection (n =7) and postoperative bleeding (n =2).After a median follow-up of 46 (23,71) months,38 cases (88.37％) were disease-free;two cases (4.65％) with tumor recurrence;one case of pancreatoblastoma died of tumor recurrence.Two cases lost to follow-up.Three patients had long-term complications,including chronic fatty diarrhea (n =2) and hypoglycemia (n =1).Three patients underwent second operation for recurrent tumor (one pancreatoblastoma and two solid pseudopapillary tumor).Conclusions SPDP is safe and effective in the treatment of tumors of the body and tail of the pancreas in children.
ABSTRACT
Objective The aim of this study was to explore whether the down-regulation of tumor suppressor gene PRDM5 is one of the mechanisms of HPV16 virus infection leading to cervical cancer. Methods The expressions of PRDM5 protein and HPV16 E6/HPV18 E6 protein in cervical cancer tissues and normal cervical tissues were detected by immunohistochemistry. After transfected with HPV16 E6 shRNA plasmid,the expression of PRDM5 gene was detected in SiHa cells by RT-PCR and Western blot. Results The positive expression rate of HPV 16/18 E6 in cervical cancer tissues was significantly higher than that in normal cervical tissues. The expression level of PRDM5 protein in cervical cancer tissues was lower than that in normal cervical tissues. After HPV16 E6 shRNA3 was transfected into SiHa cells to interfere with the expression of HPV16 E6 gene,the expression of PRDM5 at mRNA and protein levels was up-regulated in SiHa cells. Conclusion PRDM5 may mediate the development of cervical cancer caused by HPV16 virus infection.
ABSTRACT
Objective The aim of this study was to analyze the expression of RIZ 1 and its association with clinicopathological factors or radiosensitivity in cervical squamous cell carcinoma.Methods 159 samples from patients with FIGO stage Ⅱb and Ⅲa cervical squamous cell carcinoma were collected and preserved be-fore radiotherapy.The expression of RIZ1 in cervical squamous cell carcinoma tissues and 20 normal cervical tis-sues was assessed by immunohistochemistry.The relationship between the RIZ1 expression and the clinicopatho-logical factors or radiosensitivity in cervical squamous cell carcinoma was analyzed by statistical analysis.Results The expression of RIZ1 protein was down-regulated in patients with cervical cancer(P<0.001).The level of RIZ1 protein expression was close related to radiosensitivity(P=0.012),FIGO staging(P=0.004),deep myo-metrial invasion(P=0.026),and pelvic lymph node metastasis(P=0.005).Logistic regression analysis showed that the high expression of RIZ1protein was an independent predictor of radiosensitivity in cervical cancer(P=0.045).Conc lusion RIZ1 may be involved in the occurrence and development process of cervical squamous cell carcinoma and regard as a candidate biomarker for the sensitivity in cervical squamous cell carcinoma in ra-diotherapy.

ABSTRACT
Objective: To investigate the expression of cyclase-Associated protein 1 (CAP1) in breast cancer tissues and its clinical significance. Methods: Overall 93 specimens of breast cancer tissues and the paracancerous tissues were collected. The expressions of CAP1 and Ki-67 in breast cancer tissues and the para-cancerous tissues were detected by immunohistochemistry. The correlations of CAP1 with clinicopathological features and the prognosis were analyzed. Results: The expression levels of CAP1 and Ki-67 in breast cancer tissues were higher than those in the para-cancerous tissues (both P 0.05). There was a positive correlation between CAP1 expression and Ki-67 in breast cancer tissues (r 2 = 0.403, P = 0.002). The differentiation, axillary lymph node status, CAP1 expression and Ki-67 were independent prognostic factors of breast cancer (all P < 0.05). Conclusion: The expression of CAP1 is high in breast cancer tissues. CAP1 may play an important role in proliferation in breast cancer cells.
ABSTRACT
Objective To evaluate the efficacy and safety of low?level laser therapy(LLLT)for androgenetic alopecia, and to compare the therapeutic effect of LLLT alone versus in combination with finasteride tablets. Methods Thirty?nine male patients were randomly divided into the LLLT group(n=21)and combination group(n=18)to be treated with LLLT alone or in combination with oral finasteride tablets(1 mg/d)for 6 months. LLLT was given twice a week, and each session lasted 30 minutes. All the patients were photographed and asked to fill a questionnaire about subjective symptoms, and hair density (the number of hairs per unit area on the scalp) was determined by using a dermatoscope to evaluate the grade of alopecia, before the treatment, and 3 and 6 months after the treatment. Results The hair density in the LLLT group was significantly higher after 6 months than after 3 months of treatment and before the treatment(184.59 ± 21.17 vs. 169.24 ± 29.21 and 166.67 ± 32.94 hairs/cm2, both P 0.05). The hair density in the combination group significantly increased after 6 and 3 months of treatment compared with that before the treatment(201.80 ± 16.55 and 186.39 ± 17.97 vs. 157.85 ± 27.97 hairs/cm2, both P 0.05), but the combination group showed increased hair density compared with the LLLT group after 3 and 6 months of treatment(both P 0.05). During the treatment, 24(62%)patients felt less greasy, and 22(56%)reported less hair loss, with no discomforts reported by the patients except local warm feeling. Conclusion LLLT is indeed effective for the treatment of androgenetic alopecia with no adverse reactions.
ABSTRACT
Objective To study the relationship between insulin resistance and renin-angiotensin-aldosterone system (RASS) in newly diagnosed type 2 diabetes mellitus, and to provide the best treatment for type 2 diabetes mellitus with hypertension . Methods Ninety cases of newly diagnosed type 2 diabetes mellitus were included. After stratified by gender, all the patients were divided into hypertension group and non-hypertension group. According to whether taking hypotensor, the patients with hypertension were further divided into non-medication group, calcium channel blockers (CCB) group, and angiotensin receptor blockers (ARB) group respectively. Results In female patients with hypertension, the IAI, levels of rennin and angiotensin II were higher than those in non-hypertension group and the systolic pressure of female patients taking ARB was lower than those taking CCB. Pearson′s correlation analysis showed that angiotensin II and aldosterone was positively correlated with HOMA-IR but negatively correlated with IAI in females. Conclusions In female newly diagnosed type 2 diabetes mellitus , RASS is related to the development of insulin resistance , so RASS antagonists are the first choice to achieve better blood glucose control in female patients.

ABSTRACT
Objective To analyze the relationship between the clinical features of hepatoblastoma and serum alpha-fetoprotein level.Methods We did a retrospective study in 74 cases into the relationship of clinical stages,treatment,prognosis,and AFP value in hepatoblastoma.Results In Stage Ⅰ and Ⅱ patients,the average AFP was (36 333 ± 13 782) ng/ml and in Stage Ⅲ and Ⅳ,the average AFP was (78 346 ± 27 956) ng/ml,P ＜ 0.05.68 patients received preoperative chemotherapy with alpha-fetoprotein determinations before and after chemotherapy respectively.In 44 cases AFP decreased ＞ 50％ after chemotherapy,and in 20 cases AFP declined ＞90％,while in 13 cases AFP increased after chemotherapy.15 cases had serum AFP measured on the first postoperative day,among them 10 cases had a ＞ 50％ AFP decline,3 cases had a ＜ 50％ AFP decline,while in 2 cases AFP value increased.52 cases were postoperatively followed-up,with overall 3 year-survival rate of 86.5％ ; 7 cases recurred,4 died.The average preop AFP level in 7 recurred cases was (27 060 ± 3 569) ng/ml,while the average preop AFP level in those of 3-year recurrence-free was (29 865 ± 5 867) ng/ml,P ＞ 0.05.Only 57％ tumor recurred cases had back to normal AFP level within one month postop,while 89％ long term survivals reported normal range of AFP during that period,P ＜ 0.05.Conclusions Serum AFP level in patients with hepatoblastoma is related to the course of disease.It can be used to estimate the effect of clinical chemotherapy.The speed of alpha-fetoprotein decline postop can be used as an indicator of prognosis.The postoperative normal AFP level within 4 weeks predicts a favorable prognosis.
ABSTRACT
Objective To study the expression of epidermal growth factor receptor (EGFR) in cervical car-cinoma and cervical intraepithelial neoplasia(CIN),and to elucidate its relation with the genesis, infiltration, metas-tasis and prognosis of cervical carcinoma. Methods EGFR was determined by means of S-P immunohistochemistry in tissue of 100 cases of cervical carcinoma,60 cases of CIN and 40 cases of controls. Results The overexpression rates of EGFR were 0% (0/40), 51.67% (31/60),78.00% (78/100), respectively in normal cervical epithelium, CIN and cervical tumor tissues. The overexpression rate of EGFR was significantly higher in cervical tumor tissue than in control group(P<0.01). The overexpression of EGFR didn't demonstrate significant association with clinical staging, tumor size, pathological type, differentiation, cervical invasion depth, cervical canal invasion, lymphnode me-tastasis or the prognosis of cervical neoplasm (P>0.05). Conclusion Overexpression of EGFR is worsened with the severity of cervical lesion, suggesting that overexpression of EGFR is correlated with the genesis of cervical neo-plasms,which may be a valuable biological indicator of cervical carcinoma,but is not correlated with clinical patho-logical features and prognosis of cervical carcinoma.
