Objective To explore clinical value of tumor specific growth factors (TSGF) in serum and bronchoalveolar lavage fluid (BALF) on differential diagnosis of benign and malignant periphery solitary pulmonary nodules (PSPN). Methods Serum and BALF from both normal and afflicted side were collected from 211 patients with PSPN(case group) and from 196 patients without any type of tumor (control group). TSGF and carcinoembry-onic antigen (CEA) in serum and BALF were measured in both groups. Results In the malignant PSPN patients, CEA in serum, normal and afflicted side were 28.73 (SD: 15.61) μg/L,63.31 (SD:21.28) μg/L and 85.54(SD: 26.19)μg/L,respectively, which was significantly higher than that of the benign PSPN patients (7.21(SD:2.43) μg/L, 12.36(SD:6.93)μg/L and 14.65 (SD:8.07)μg/L,respectively), as well as that of the control group (4.68 (SD: 1.25) μ/L and 11.06(SD:8.03) μg/L in serum and BALF, respectively (P < 0.05). TSGF in the serum and BALF from the normal and afflicted side of malignant PSPN patients was 88.73 (SD:13.51)μg/L, 110.73 (SD: 18.64) μg/L and 162.80(SD:58.89) μg/L, respectively, which were significantly higher than that of the benign PSPN patients (56.31(SD: 2.43) μg/L, 79.25 [SD: 36.86] and 86.29 (SD: 37.07) μg/L, respectively) (P <0.05). Furthermore, in the malignant PSPN patients, TSGF and CEA in the afflicted side were significantly higher than that of the normal side. Sensitivity, specificity and accuracy of TSGF in BALF from the afflicted side for malig-nant diagnosis were 86.6%,100.0% and 98.6%,respectively,which was higher than that of CEA (70.2% ,78. 9% and 76.5% respectively) and that of serum TSGF (73.1% ,88.9% and 85.7% respectively). Conclusions TSGF in bronchoalveolar lavage fluid and serum has a significant role in differential diagnosis of benign and malig-nant periphery solitary pulmonary nodules. Furthermore, measurement of TSGF in bilateral BALF is helpful in diag-nosis of tumor location.

Methods The failure mode and effect analysis (FMEA) were used to analyze the potential risks in children with tracheal foreign body removal, preoperative, intraoperative and postoperative care, and to find out the possible risks in each medical treatment. For pediatric venous puncture technology was not skilled, surgical position placement inappropriate (especially in the case of foreign body removal surgery posture), surgical instruments and equipment management, intraoperative nursing cooperation and observation of the disease, postoperative transfer and other aspects of the transfer of training and improvement. Results The medical risk value (RPN) in the treatment of pediatric tracheal foreign body removal in the process of nursing in the control group was reduced from 1 284.2 to 213.2 of the experimental group. The average value of doctors' satisfaction was increased from 79.33% in the control group to 93.33%in the experimental group, P<0.05, the difference was statistically significant. Conclusions The use of FMEA in the treatment of pediatric tracheal foreign body removal surgery care and medical risk management improve the quality of surgical care and help improve the success rate of tracheal foreign body removal. It also ensures the safety of the children in the operation process and improves the quality of nursing work.

To obtain the P8 protein of Rice gall dwarf virus (RGDV) with biological activity, its outer coat protein gene S8 was expressed in Spodoptera frugiperda (Sf9) insect cells using the baculovirus expression system. The S8 gene was subcloned into the pFastBacTM1 vector, to produce the recombinant baculovirus transfer vector pFB-S8. After transformation, pFB-S8 was introduced into the competent cells (E. coli DH10Bac) containing a shuttle vector, Bacmid, generating the recombinant bacmid rbpFB-S8. After being infected by recombinant baculovirus rvpFB-S8 at different multiplicities of infection, Sf9 cells were collected at different times and analyzed by SDS-PAGE, Western blotting and immunofluorescence microscopy. The expression level of the P8 protein was highest between 48-72 h after transfection of Sf9 cells. Immunofluorescence microscopy showed that P8 protein of RGDV formed punctate structures in the cytoplasm of Sf9 cells.

It can be used to assess the risk of severe psychiatric patients in community.

Objective To investigate the effects and values of extracorporeal membrane oxygenation (EC-MO) used in patients after cardiac arrest. Method During five years period from June 2002 to June 2007,fifteen cases taken for cardiopulmonary resuscitation were treated by using ECMO in the emergency department and ICU. All the measures for disgnosis and treatment were observed to the guidelines for cardiopulmonary resuscitation and emergency cardiovasculat care set by the American Heart Association in 2005, and ECMO was applied in addition. The study was a self-comparison trial. The biomarkers including heart rate (HR), mean arterial pressure (MAP), central venous pressure( CVP) , arterial partial oxygen pressure (PaO2), arterial partial pressure of carbon dioxide ( PCQ2), oxygen saturation (SaO2), hydrogen power (PH), and concentration of lactic acid were taken and assayed before and 10 min, 1 h,6 h, 12 h, and 24 h after treatment. Differences between the results of measurements were analysed by t -test for matched pairs using SPSS version 10.0 software package. Neurological sequelae was also observed and described. Results Ten minutes after ECMO treatment, MAP rose dramatically (P < 0.01) and got to further higher level one hour later ( P < 0.05). On the other hand, CVP dropped off 10 minutes after ECMO treatment and further lowered one hour later, and PaO2 and SaO2 were improved apparently ( P < 0.01), and pH was increased significantly (P < 0.01), while a derease in concentration of arterial LA of significantly (P < 0.01). Of the 15 cases, 11 patients got well,including completely recovered without sequelae in 5,memory disorders in 2 and hemipleggia in 2 patients. Conclusions ECMO provides effective blood flow to hearts, and therefore, improves oxygenation and oxygen consumption greatly. Moreover, it provides stable oxygenated blood to brain and therefore, it is a good approach to cardiopulmonary cerebral resuscitation.

OBJECTIVETo investigate the changes in local endometrial contents of estrogen receptors (ER) and progesterone receptors (PR) after insertion of levonorgestrel-releasing intrauterine system (LNG-IUS) and evaluate the efficacy of LNG-IUS in treating endometrial hyperplasia.

METHODSThe endometrial histological changes were observed in 25 anovulatory women with dysfunctional uterine bleeding after insertion of LNG-IUS, and the contents of ERs and PRs in the endometrium were measured by immunohistochemistry.

RESULTSThe endometrial proliferation activity was obviously inhibited 6 months after LNG-IUS insertion with decreased endometrial glands, glandular dysplasia and decidualization of interstitial cells. The positive cell rate for ERs and PRs in the glandular epithelial and interstitial cells were significantly reduced after LNG-IUS insertion.

CONCLUSIONSLNG-IUS can reduce ER and PR expressions in the endometrium and inhibit endometrial proliferation, and therefore can be effective in treating simple and complex endometrial hyperplasia.

OBJECTIVE: To analyze the prenatal ultrasonic characteristics and genetic features of 14 fetuses with chromosome 22q11 microdeletion syndrome (22q11DS). METHODS: 4989 fetuses were analyzed by using single nucleotide polymorphism array (SNP array) in the Fujian Maternal and Child Health Hospital from November 2016 to November 2019. RESULTS: SNP array showed that 11 fetuses had classic 3 Mb microdeletion in 22q11 region, one fetus had 2.0 Mb microdeletion, and two fetuses had 1.0 Mb microdeletion. The 1.0 Mb microdeletion in 22q11 region contains SNAP29 and CRKL genes, which may increase the risk of congenital renal malformation and cardiovascular malformation. CONCLUSION Prenatal ultrasonic characteristics of fetuses with 22q11 microdeletion syndrome vary, and SNP array is a powerful tool to diagnose such diseases, which can provide accurate genetic diagnosis and enable prenatal diagnosis.
