Objective To investigate the effect of postoperative analgesia with oxycodone on T cell function after operative of cesarean section with chronic hepatitis B.Methods Sixty cesarean sec-tion women with chronic hepatitis B undergoing CS,aged 22-35,were randomly divided into two groups:oxycodone group (group O)and morphine group (group M).The changes of immune cells (Th1,Th2)and liver function were recorded after the analgesia (immediate,postoperative 24 h,48 h,72 h).The total number of pressing analgesia pump and the cumulative amount of PCA were re-corded.Results The Th1 of group O was higher than that of group M at 24 h,48 h after operation (P <0.05),while there was no significant difference of Th1 and Th2 in group M.The total patient-controlled pressing times and accumulated amount of PCA of group O were significantly lower than those in group M (P <0.05).There was no significant difference in the incidence of adverse reactions between the two groups.Conclusion Oxycodone can activate T cell function in postoperative analge-sia,while morphine causes the inhibition of Th1 cells.

Objective To detect the changes of hemodynamics in patients with portal vein embolization (PVE) before surgery for hilar cholangiocarcinoma, and analyze the relationship between hemodynamics and liver hypertrophy. Methods The clinical data of 21 patients with hilar cholangiocarcinoma who were admitted to the Eastern Hepatobiliary Surgery Hospital from April 2008 to December 2009 were retrospectively analyzed.Relevant hemodynamic variables were detected and analyzed before and 3, 7, 14 days after PVE. Data were processed using Student t test or linear correlation analysis. Results The main portal vein pressure after PVE was (25.9 ± 4.1 ) cm H2O ( 1 cm H2O = 0.098 kPa), which was ( 3.5 ± 2.5 ) cm H2O higher than that before PVE [( 22.4 ± 4.1 ) cm H2O] ( t = - 6. 504, P ＜ 0.05 ). The blood flow velocity in the non-embolized branch of portal vein increased after PVE, and reached peak [(26 ±9)cm/s] at the seventh day after PVE. A positive correlation was found between the hypertrophic rate of the non-embolized lobes and the ratio of embolized lobes to total liver volume ( r = 0. 593, P ＜ 0. 05 ). Conclusion Greater scope of the embolized vascular bed of portal vein induces higher hypertrophic rate of non-embolized liver.

OBJECTIVE: To analyze the causes of misdiagnosis in patients with familial nasal bleeding and to improve the level of diagnosis and treatment. METHOD: The clinical characteristics of 7 families with nose blood were analyzed retrospectively and 2 typical cases were reported, including their treatment and misdiagnosis in consulting, out-patient and in-patient. RESULT: Typical case 1 was misdiagnosed and mistreated for 42 years, misdiagnosed as blood disease so that the patient was biopsied in bone marrow, misdiagnosed as endometriosis so that the patient was performed uterus resection. Typical case 2 was misdiagnosed and mistreated for 17 years, misdiagnosed as upper digestive tract hemorrhage so that the patient was performed endoscopic sleeve ligation, misdiagnosed as inferior turbinate hemangioma so that the patient was performed nasal endoscopic surgery. CONCLUSION Neglect of family history and the typical signs are the causes of misdiagnosis. So asking about the family history and checking for the typical signs in patients with nose blood can avoid misdiagnosis.

OBJECTIVEThe present study is concerning qualitative and quantitative detection of Poria cocos quality based on FT-near infrared (FT-NIR) spectroscopy combined with chemometrics.

METHODThe Poria cocos polysaccharides contents were determined by UV. Transmission mode was used in the collection of NIR spectral samples. The pretreatment method was first derivation and vector normalization. Then principal component analysis (PCA) was used to build classification model and partial least square (PLS) to build the calibration model.

RESULTThe results showed that conventional criteria such as the R, root mean square error of calibration (RMSEC), and the root mean square error of prediction (RMSEP) are 0.944 0, 0.072 1 and 0.076 2, respectively. The misclassified sample is 0 using the qualitative model built by PCA.

CONCLUSIONThe prediction models based on NIR have a better performance with high precision, good stability and adaptability and can be used to predict the polysaccharose content of Poria cocos rapidly, which can provide a fast approach to discriminate the different parts of Poria cocos.

Objective To analyze the clinical and pathological characteristics of Alport syndrome in children. Methods Clinical and pathological information gathered from 62 patients during March 1989 to August 2012 was retrospectively analyzed. Results Four autosomal recessive Alport syndromes (AR-AS) and 58 X-linked Alport syndromes (XL-AS) were analyzed. Of the XL-AS, 47 were boys and 11 were girls. Most of patients induced by upper respiratory tract infections, and onset with hematuria and proteinuria. There was no signiifcant gender difference in family history, impaired renal tubular proteins, hypertension, im-paired renal function, hearing loss, ocular abnormalities or renal pathological changes under light microscopy. However, extensive lamination and split of glomerular basement membrane (GBM) dense layers were found in 83.0%male and 18.2%female patients (P=0.000) and the rest patients were presented with limited distribution of typical GBM changes. Proteinuria progressed signiif-cantly with age in XL-AS males (r=0.501, P=0.000). Five XL-AS patients developed to end stage renal disease (ESRD) between 11 to 16 years old. Conclusions XL-AS is the main inherited type and severe changes of GBM are common in XL-AS males. Proteinuria increases remarkably with age. The detection of type IV collagen in renal tissue or skin is helpful to diagnose Alport syndrome and conifrm inheritance modes.

OBJECTIVETo investigate the antiviral activity of 3-hydroxyphthalic anhydride-modified ovalbumin (HP-OVA) against herpes simplex virus 2 (HSV-2) in vitro.

METHODSBy chemical modification, ovalbumin (OVA) was treated with 3-hydroxyphthalic anhydride (HP) to prepare HP-OVA. The anti-HSV-2 activity against HSV-2 333 virus in vitro and the cytotoxicity of HP-OVA in African green monkey kidney cells (Vero cells) were detected by MTT colorimetric assay. The inhibitory effects of HP-OVA on 17 strains of vaginal lactobacilli were observed by microscopy.

RESULTSAnhydride-modified ovalbumin significantly inhibited the infection by HSV-2 with an IC(50) of 23.56±8.33 µg/ml. HP-OVA showed only low cytotoxicity to the host cells with a CC(50) over 1 mg/ml. HP-OVA did not produce significant inhibitory effect on the 17 strains of vaginal lactobacilli (MIC>1 mg/ml).

CONCLUSIONAnhydride-modified protein HP-OVA exhibits potent anti-HSV-2 activity in vitro and can be a good microbicide candidate for prevention of sexually transmitted diseases.

OBJECTIVETo explore the feasibility of electroacupuncture compound anesthesia in radiofrequency ablation for hypertrophic inferior turbinate.

METHODSThe patients confirmed to the enrolled criteria were randomly divided into an observation group (n = 31) and a control group (n = 30). The observation group was treated with electroacupuncture at Sibai (ST 2), Xiaguan (ST 7), Hegu (LI 4) and Zhigou (TE 6) on the left side and routine local anesthesia on the right side. The control group was treated with routine local anesthesia on the both side. The feelings of pain, circulatory index and operation effect were observed and compared.

RESULTSDuring radiofrequency ablation, the pain grade of two measurements on the left side and the 2nd measurement on the right in the observation group were all lower than those in the control group (all P<0.05). In the observation group, the pain grades on the left side were lower than that on the right side (P<0.05), and the systolic blood pressure and the heart rate were lower than that in the control group when undergoing the 2nd radiofrequency ablation on the right side and on the left side, respectively (both P<0.05). There was no significant difference in operation effect between the two groups.

CONCLUSIONElectroacupuncture compound anesthesia can meet the analgesia requirement of radiofrequency ablation for treatment of hypertrophic inferior turbinate, and would be helpful to prevent cyclic fluctuation during the operation at the same time.

OBJECTIVETo figure out the function of C/EBPalpha in the monocytic differentiation of HL60 cells induced by a new steroidal drug NSC67657.

METHODSThe differentiation of HL60 cells was induced by NSC67657, and the cell surface antigen CD14 expression was detected by flow cytometry. The gene and protein expressions of CCAAT enhancer binding protein alpha (C/EBPalpha) before and after the induction of cell differentiation were determined by RT-PCR and Western blot. Eukaryotic expressing vector pDsRed-ICAT was constructed and transfected into HL60 cells, and its expression was verified. The effect of C/EBPalpha overexpression in HL60 cells was assessed by MTT assay, Wright's staining and flow cytometry before and after NSC67657 transfection.

RESULTSHL60 cells could be induced into monocytes by 10 micromol/L ATRA within 5 days, and the coverage of CD14 positive cells reached 93.9% after 5 days of drug treatment. The eukaryotic expressing vector was successfully constructed, and over 90% positive clones were obtained after screening by G418 and electrotransfection. The results of proliferative analysis, chemical staining, ultrastructural observation, and CD11b detection confirmed that HL60 cells could be induced into granulocytic differentiation by overexpression of C/EBPalpha protein. Moreover, in the drug treatment group, transfected cells could not be induced into monocytic differentiation, and their granulocytic differentiation was also inhibited.

CONCLUSIONThe monocytic differentiation of HL60 cells induced by NSC67657 may not be via the regulation by C/EBPalpha protein-mediated signal transduction. However, the overexpression of CEBPalpha may inhibit the process of NSC67657-induced monocytic differentiation in HL60 cells.

Objective To explore the clinical characteristics of renal transplantation in patients with diabetes mellitus (DM)-induced end-stage nephropathy.Methods The clinical data of 408 cases who underwent renal transplantation in our center from 2009 to 2013 were retrospectively analyzed.The patients were divided into DM group (n =82) and non-DM group (n =326).The postoperative infection,delayed graft function (DGF),adverse events,and the survival rate of patients/kidneys were comparatively analyzed.Results The incidence of postoperative infection,DGF and adverse events was significantly higher in DM group than in non-DM group (23.2％ vs.15.6％,P =0.04;17.1％ vs.8.6 ％,P =0.04;13.4％ vs.8.3 ％,P =0.03).No significant difference was found in the 1-,2-,and 3-year survival rate of patients and kidneys between the two groups after operation (P＞ 0.05).Conclusion The incidence of postoperative infection,DGF and adverse events is higher in DM patients.The DM does not affect the survival rate of patients/kidneys through appropriate treatment.It is important to prevent complications in DM patients after renal transplantation.

OBJECTIVE: To investigate the clinical characteristics and mechanism of cervicogenic headache. METHODS: Fifty-seven patients with cervicogenic headache who were treated from May 2013 to December 2017 and had complete imaging data were selected, including 18 males and 39 females with an average age of(43.26±10.39) years old ranging from 20 to 63 years old. The duration of the disease was 4 months to 35 years with a mean of (11.74±9.47) years. The pain situation, iconography and Tinel sign were analyzed. RESULTS: The patients with cervicogenic headache often had bilateral pain. The regions mainly concentrated in the temporal region, with occipital, head or orbit pains. The VAS scores decreased with the duration of the disease. There were many cases of disc herniation(91.30%), vertebral instability(73.91%), atlantoaxial displacement(56.52%), curvature change of cervicogenic vertebra(54.35%). The number of positive Tinel sign points was between 3 and 24 (13.58±5.8) per patient. The number and extent of Tinel sign were significantly different between the affected side and healthy side(<0.05). C₂,₃ facet joints(92.98%), post mastoid(89.47%), occipital concavity(89.47%), C₃,₄ facet joints(84.21%), third occipital nerve(80.70%) were the positive Tinel sign points in patients with cervicogenic headache. CONCLUSIONS The iconography changes of cervicogenic headache and Tinel sign may contribute to the clinical diagnosis and mechanism of the disease.
