Objective To investigate the detection of early cervical cancer patient's peripheral blood CK19 mRNA and its clinical significance. Methods 30 early (ⅠA2~ⅡA) cervical cancer patients from the department of gynecological tumors in the third affiliated hospital of Kunming Medical University were selected as experimental group, 15 patients with uterine myoma and 15 healthy volunteers as negative control group,15 advanced (ⅡB~ⅢB) cervical cancer patients as positive control group. Peripheral blood samples before receiving radical resection of experimental group,and the same samples before treatment of control groups were collected. The change of relative expression level and positive rate of peripheral blood CK19 was analyzed using qRT-PCR technique, and its correlation with clinicopathological parameters and prognosis was further analyzed. Results There was significant difference in relative expression level of CK19 mRNA in the peripheral blood between experimental group and control groups ( <0.001) . And the positive rate of CK19 in the peripheral blood from 30 patients with early cervical cancer before operation in the experimental group was 30% (9/30) . Furthermore, CK19 mRNA positive rate before surgery was correlated with lymph node metastasis, muscularis invasion and pathologic risk factors for postoperative ( <0.05) . There were no significant correlation between CK19 mRNA positive rate and other clinical and pathological features such as age,clinical stage (FIGO),tumor cell differentiation,tumor size,pathological type and etc ( > 0.05) . Conclusions CK-19 mRNA is a specific and suitable molecular marker for the detection of circulating tumor cells in early cervical cancer. Detection of peripheral blood CK19 mRNA expression before receiving radical hysterectomy in patients with early cervical cancer can also make up for the disadvantage of other methods such as the imaging, tumor marker detection. Most important of all, it can provide the basis for choosing a proper adjuvant therapy post-operation and estimating the relapse and prognosis.

Objective To analyze the clinical features of 35 patients with Silver-Russell syndrome (SRS) in Beijing Children's Hospital in recent 6 years,and to recognize the clinical manifestations and improve the diagnosis of the disease.Methods The diagnostic criteria of SRS were studied retrospectively,the differences among 3 different diagnostic criteria were compared.Results Thirty-five SRS patients were diagnosed by means of 3 criteria,over a period from 2006 to 2012.There were 23 males and 12 females,with age range 0.08 ～ 12.15 yr.77 ％ of cases met the three criteria,97％ met two of the three criteria.There were dwarfism in 33 cases (94.2％),genital abnormalities in 1 case (2.9％),and asymmetry of limbs in 1 case (2.9％).The clinical characteristics with the frequencies accounting for over 80％ included short stature (average height-3.61 SDS),leanness (body mass index ＜-2.11SDS),bone dysmorphism including triangular face,irregular teeth,asymmetry of limbs,clinodactyly of fifth finger,and bone age obviously lagged behind.60％ of the cases showed bone age lagging behind more than 1 year.Height lagging behind was more obviously then bone age.Conclusions The diagnosis of SRS is mainly based on Clinical manifestation,laboratory and biochemical examinations are of no avail.There is a high coincidence with the 3 different diagnostic criteria.Clinical features in more than 80％ patients with SRS are short stature,craniofacial triangular dysmorphism,irregular teeth,limbs asymmetry and fifth finger clinodactyly,and mild lagging behind of bone age.

Objective To compare the difference of impact on the cellular immunity between laparoscopic and transabdominal radical hysterectomy. Methods 60 patients with early cervical cancer (Ⅰa2~Ⅱa1), half of them were assigned to do abdominal radical hysterectomy (ARH) and the other half for laparoscopic radical hysterectomy (LRH). Adopt flow cytometry (FCM) detect peripheral blood T lymphocyte subsets, NK cells, CIK cells and T lymphocyte ac-tivation function on one day before surgery, one day, five days, and 28 days after the surgery separately. Compare the changes of immune status. Results After one day, the number of T lymphocyte subsets declined compared with preoperative one day(P <0.05). After five days, each index in LRH group was increased compared with postoperative one day, and the degree of decline is less than the ARH group ( P< 0.05), and recovered faster. After one day, the number of HLA-DR+CD3+in LRH group compared with the preoperative one day declined and HLA-DR+CD8+in-creased, and the degree of change is less than the ARH group, and recovered faster. Conclusions Immune function in patients after laparoscopic group was less changed, and recovered quickly, while the immune function were less inhibited, it may protect patients' immune function better.

Objective The report was focused on polycystic ovary syndrome(PCOS) in female adolescents related to homosexual precocious puberty,and the new awareness of its influence on long-term health of homosexual precocious girls.Methods A girl with idiopathic central precocious puberty (ICPP) but diagnosed as PCOS in adolescence was reported and the data were reviewed.Results A girl was diagnosed as ICPP when she was near 8 years old with obesity,but without hyperinsulinemia,then she received the treatment of a 3.75 mg dose gonadotropin hormone analogues (GnRHa) every 28 days.Her gonads development was under control while her growth was arrested.Growth hormone(GH) injection started at 13 months.She stopped all medications when finished GH and GnRHa treatment for 12 months and 25 months.She went to see doctors again because of no menarche after discontinuing medication for nearly 2 years.She appeared obese and acne,hirsutism,athanens negricans and purple purple striae on the skin.Hyperinsulinemia and hypertestosterone were demonstrated.Pelvic B ultrasonography showed polycystic ovary,and she was diagnosed as PCOS.She was ordered to lose weight and to take metformin.And adrenocorticotropic hormone stimulating test was done,and B ultrasonography again ruled out atypical congenital adrenal hyperplasia and tumor of adrenal gland.She got her menarche 1 month later.Twelve months after the PCOS diagnosis and treatment,she had 4 menses,her insulin level decreased,glucose tolerance and her serum testosterone level turned normal.At the same time,the form of ovarian and follicular was significantly reduced.After taking mefformin for 20 months,her height and weight did not change,her menstrual was regular every 35-40 days,each time lasting about 7 days.She was followed up.We also reviewed literatures and learnt that precocious puberty might not be a benign situation and it might have an intrinsic relation to obesity,precocious puberty and PCOS.It might be the cofactors for causing PP and PCOS that accessed luteinizing hormone(LH) secretion and disorder of hypothalamus pituitary gonad(HPG) axis except obesity with hyperinsulinemia.Reported pubertas praecox in childhood developed to PCOS at 30％ with high prevalence of obesity.GnRHa suppressive therapy might relate to PCOS and had disputation for improving final height.There were fewer investigations on adolescent PCOS,and no consensus guideline on it in China.Conclusions Girls with ICPP may develop to PCOS some time later.The clinical features of the reported girl and the knowledge from literatures support the hypothesis that inner relationship between the CPP and the PCOS.The LH high secretion and disorder of HPG axis may be the causes of them; LH treatment on suppressing obesity should be cautious during treatment.The benefit and risk from GnRHa treatment should be evaluated thoroughly.Further clinical research should be conducted on adolescent PCOS.

ObjectiveTo assess gene chip application value in detecting pathogenic bacteria in intracranial infection cases.MethodsPrimers and probes aiming at the specific DNA sequences of 4 kinds of common pathogenic bacteria and 6 kinds of common drug resistance genes (DRGs) were designed and used to identify the bacteria and DRGs among 30 cerebrospinal fluid (CSF) specimens (12 positive,18negative in CSF culture) from patients with intracranial infection using multiplex polymerase chain reaction (mPCR) and gene chip.The results of gene detection were compared with those of CSF culture and drug sensitivity testing.ResultsBacteria were identified and DRGs were detected in 15 specimens; DRGs and 16S gene were detected in 8 specimens; neither bacterium nor DRG was detected in 7 specimens.ConclusionGene chip technique is characterized by its relative sensitivity and rapidity of detecting the pathogenic bacteria in CSF of intraeranial infection cases.

A 2-month-and-20-day-old girl was hospitalized because of slow weight gain for 20 days.The patient was diagnosed as anemia,pneumonia and neutrophils firstly,and showed no improvement during anti-infective therapy,blood transfusion,and leukopenia drugs.The urinary organic acid spectrum of the patient showed increased methylmalonic acid slightly,but the normal value was found by 4 tests,which was inconsistent with the typical methylmalonic aciduria.By analyzing clinical manifestations and plasma homocysteine,folic acid and vitamin B12 levels,she was considered to have intracellular cobalamin metabolic disorder.Then,normal diet,intramuscular injection of vitamin B12,and feeding calcium,betaine,and L-carnitine were given,and the girl's symptoms were improved significantly.Latter gene analysis further showed that the patient had methylmalonic aciduria CblC type.Clinical manifestations of methylmalonic aciduria are complex and individually various,different therapies showed be applied to different causes.The value of urinary methylmalonic acid level alone cannot judge etiology;diagnosis should be based on blood amino acids and carnitine spectrum,homocysteine level and vitamin B12 level.

Objective To investigate the incidence of newly-onset type 1 diabetes mellitus ( T1DM ) complicated with ketoacidosis(DKA) and its relevant factors in pediatrics. Methods Hospital records of 317 T1DM children below 18 years of age, diagnosed from 2010 to 2012 were reviewed. By using retrospectively analyzed data of inpatients with newly-diagnosed T1DM, the incidence of DKA was calculated. In this study, the influential factors of DKA included gender, age, residence, family history of diabetes mellitus, duration of symptoms, misdiagnosis or missed diagnosis, and delayed treatment. Patients were divided into two groups:group 1, aged<5 year and group 2, aged>5 year. Results Of all patients diagnosed with T1DM, 175 ( 55. 2%) presented with DKA, and mild, moderate, and severe DKA accounted for 26. 5%, 23. 9%, 49. 6%, respectively. The incidences of DKA in group 1 andgroup2were67.5% and48.0% (P=0.001),withthehighestfrequency(70.3%)inpatientsaged<2 years. The proportion of severe DKA in group 1 was significantly higher than that of group 2 (60. 0% vs 41. 3%, P=0. 048). The rates of misdiagnosis and missed diagnosis in the two groups were respectively 27. 4% and 12. 0%(P=0. 001), being 37. 8% in children<2 years. The HbA1C level of group 1 was lower than group 2 (11. 50% vs 12.54%,P=0.001). Intheacutemetabolicandhoneymoonperiod,Cpeptidelevelsofgroup1werebothlowerthan those of group 2 [(0. 36 vs 0. 55) ng/ml, P=0. 001;(0. 40 vs 0. 61) ng/ml, P=0. 02]. The DKA incidence of patients with misdiagnosis or missed diagnosis was significantly increased(83. 9% vs 49. 0%, P=0. 000). Compared with those without DKA, C peptide level of patients with DKA was lower in the acute metabolic period[(0. 56 vs 0.40)ng/ml,P<0. 01], but no difference in honeymoon period[(0. 67 vs 0. 59)ng/ml,P=0. 22]. Logistic regression showed that age, misdiagnosis or missed diagnosis were associated with the presence of DKA. The possibility of the occurrence of DKA in patients aged>5 years was half of patients aged<5 years ( OR=0. 448, P=0. 003), and the risk of DKA in patients with misdiagnosis or missed diagnosis was higher (OR=5. 640, P=0. 005). Conclusion DKA in patients with newly-onset T1DM is frequent and often severe. Multivariate analysis revealed that patients aged <5 years and those with misdiagnosis or missed diagnosis are encountered high risk of DKA.

Objective To analyze the effect of stroke duration on the cognitive function in the elderly population in Beijing.Methods Based on the Research Project of Beijing Chronic Disease Combined with Common Elderly Syndrome Community Management Practices,a cross-sectional study was used.From July 2013 to December 2014,the old population in 4 districts and a county (Xicheng District,Fangshan District,Tongzhou District and Yanqing County) in Beijing were sampled with the multi-stage,randomized and stratified sampling.A total of 3 024 subjects were enrolled in the study.The data were obtained from the questionnaires and clinical examinations.Mini-Mental State Examination (MMSE) was used as the evaluation index of cognitive function.The subjects were divided into either a normal cognitive function group (MMSE>26,n=1 878) or a cognitive impairment group (MMSE≤26,n=1 146) according to the MMSE scores.A multiple logistic regression model was used to analyze the effects of hemorrhagic stroke,ischemic stroke,and asymptomatic stroke,as well as disease duration on cognitive function.Results After adjusting for the confounding factors,such as sex,age,educational level,marriage,smoking,and alcohol consumption,the risks of occurring cognitive impairment in patients with hemorrhagic stroke in stroke duration for 1-3,4-10 and >10 years were OR 3.019 (95％CI 0.974-9.361,P=0.056),8.652 (95％CI 2.924-25.601,P<0.01) and 1.104 (95％CI 0.311-3.920,P=0.879) times of those without occurring stroke population;the risks of occurring cognitive impairment in patients with ischemic stroke in stroke duration for 1-3,4-10 and >10 years were 1.000 (95％CI 0.636-1.571,P=1.000),1.874 (95％CI 1.231-2.853,P=0.003),2.439 (95％CI 1.386-4.291,P=0.002) times of those without occurring stroke population.Stroke duration for 4-10 years in patients with hemorrhagic stroke and stroke duration for 4-10 and >10 years in patients with ischemic stroke were all the risk factors for occurring cognitive dysfunction.Conclusion For patients with stroke,stroke duration or long-term effects has a certain impact on cognitive function.

Objective: To analyze the effect of the use of antibiotics intervened by clinical pharmacist in diabetic ketoacidosis (DKA) patients. Method: This was a prospective clinical study with a historical control group.The group 1 was the control group which was not intervened for antibiotics use from January 2010 to November 2012. The group 2 was the intervention group treated from December 2012 to June 2016. Group 1 was divided into group 1a which included newly-onset diabetes patients and group 1b which included long standing diabetes patients. Group 2 was divided into the similar group 2a and group 2b.Clinical pharmacist supervised the implementation of terms to restrict the use of antibiotics.Changes of the rate of antibiotics use, the length of time of antibiotics use, hospital stay, the cost of antibiotics, etc.were compared. Result: In group 1a and group 2a, the rate of antibiotics use was 85%(107/126) and 31%(58/190)(χ²=25.787), the length of time of antibiotics use was 11(7-18)d and 6(4-10)d (U=1 507), the hospital stay was 23(18-27)and 20(6-24)d(U=8 177) , the cost of antibiotics was 1 615(1 000-2 970)and 1 080(504-1 932) yuan ( U=1 783), the differences had statistical significance(P<0.05). In group 1b and group 2b, the rate of antibiotics use was 97% (33/34) and 48% (23/48)(χ²=14.222), the length of time of antibiotics use was 8(6-12)d and 5(4-7)d (U=180), the hospital stay was 15(10-21)and 12(8-16)d (U=580), the cost of antibiotics was 2 200(1 356-3 100)and 1 600(705-2 200) yuan (U=223), the differences had statistical significance(P<0.05). Conclusion Clinical pharmacist intervened use of antibiotics was effective in reducing the use of antibiotics and financial burden.

Objective To analyze the CT and MR imaging features of intracranial teratomas to improve the diagnostic accuracy.Methods Twenty patients with intracranial teratomas,admitted to and performed surgery in our hospital from January 2010 and January 2014,were chosen;the teratoma was confirmed by histopathology.The CT and MR imaging features,clinical and pathology materials of these patients were retrospectively analyzed.Results Twelve immature teratomas,7 mature teratomas and one teratoma with malignant transformation were noted;18 patients were in the central line area and 2 were not.In the 9 patients performed CT scan,7 showed heterogeneous mass;peritumoral calcification was more common than intratumoral calcification,and it turned out to be round with diameter less than 1 cm,while intratumoral calcification was multifocally strip and patchy.In the 17 patients performed MR imaging,14 showed heterogeneous signal and fatty signal was detected in 3;enhanced MR imaging showed that 6 presented nodular enhancement,3 presented multilocular enhancement markedly,patchy enhancement showed in 2,and one showed marked enhancement in mural nodule and cystic wall.In 8 patients performed diffusion-weighted imaging,7 displayed hypointense to isointense and one demonstrated isointense to hyperintense.Conclusions Intracranial teratoma has some characteristic imaging features,so by combining clinical materials,it should be considered when fatty component is detected in a heterogeneous intensity tumor with multiple cystic change,calcification and a hypointense to isointense signal on DWI;however,pathology is needed to make a definite diagnosis.
