OBJECTIVE: To explore the clinical application value of using needle electrode in transurethral plasmakinetic resection of bladder tumor around ureteral orifice. METHODS: Retrospective analysis was performed on the clinical data of 16 cases who had bladder tumors around ureteral orifice and underwent transurethral resection using plasmakinetic needle electrode in Department of Urology, Peking University International Hospital from June 2015 to December 2019. There were nine cases with the tumor of one to two centimeters from the ureteral orifice. The rest of the seven cases had tumor that was within one centimeter from the ureteral orifice, including two cases whose ureteral orifice was invaded by the tumor. All the patients studied were diagnosed before surgery and contraindications were excluded. The plasmakinetic needle electrode was used to treat the tumor with en bloc resection, and all the excised tissue was sent for pathological examination. Intravesical chemotherapy and postoperative follow-ups were performed. Statistical analysis was performed on the operation time, the incidence of obturator nerve reflex, the peri-operative bleeding, the parameters of indwelling ureteral catheter or double-J stent, the incidence of postoperative hydronephrosis, the clinical stage of tumor, and the recurrence rate. RESULTS: The operation was successfully completed for all the sixteen cases. The operation time was 16 to 57 minutes, with an average of (32.6±11.8) minutes. No obvious obturator nerve reflex and perioperative bleeding occurred in all the patients. Ureteral catheters were indwelled prior to the operation of tumor resection in seven cases. Four of the seven cases had the ureteral catheters remained while the rest three were replaced by double-J stent after surgery. Postoperative pathological analysis showed that all the tumors were urothelial carcinoma, including 9 cases of low grade and 7 cases of high grade. Pathological staging: 10 cases were in Ta stage, 5 cases in T1 stage, and 1 case in T2a stage. All tumor bases and lateral margins were negative. All the patients received 3-56 months, with an average of (26.0±18.1) months of follow-up. There was no case of upper urinary tract hydronephrosis or tumor recurrence. CONCLUSION The transurethral plasmakinetic resection of bladder tumor using needle electrode can realize en bloc tumor resection without obturator nerve reflex and reduce the risk of ureteral orifice injury. It is a safe and effective surgical method for treating bladder tumors around the ureteral orifice.

OBJECTIVE To compare the treatment effects of secreory otitis media with artificial eustachian tube insertion and tympanotomy tube insertion.To provide useful information for the treatment of secretory otitis media.METHODS Seventy-one patients(86 ears) with secretory otitis media were randomly divided into tow groups:experimental group(36 cases,44 ears) and control group(35 cases 42 ears).The experimental group was treated by artificial eustachian tube insertion under nasal endoscope.Drugs were injected through the tube into the tympanic cavity everyday after flushing it. The control group were treated by traditional method—the tympanic ventilation tube.All patients were followed up for 6 months.RESULTS The experimental group: 21 ears(47.73%) were cured,19 ears(43.18%) were straightened up,and no effects observed in 4 ears (9.09%).The control group:12 ears(28.57%) cured,17 ears(40.48%) wered straightened up and no effects obsered in 13 ears(30.95%).The efficiency rate of the experimental group(90.91%) was much higher than the control group(69.05%,P

Inhibitor of growth 2 (INC2 ) is a member of INC family, and cooperates with p53 in regulating cell cycle, apoptosis, and aging. It can also facilitate chromatin remodeling and transcription regulating through histone modifications. Researches suggest that INC2 protein is an important factor in the genesis, metastasis and prognosis of many kinds of tumors. Resent studies indicate that INC2 can not be simply classified as oncogene or tumor suppressor. At present, the function of INC2 in tumorigenesis and tumor development involves interaction with varied molecules, but the mechanisms remain largely unknown, which still require further investigation.

Objective To explore the clinical function of biofeedback training in patients with high risks of postpartum depression,and to provide a new method to decrease the risk of postpartum depression.Methods From May 1,to December 31,2010,in Bayi Children's Hospital,General Hospital of Beijing Military Area Command of Chinese PLA,60 pregnant women with Edinburgh Postnatal Depression Scale (EPDS) evaluation score of 6 to 12 at 12～14 gestational weeks were randomly divided into the biofeedback training group (n=30) and the control group (n=30).The control group learned prenatal care knowledge in pregnant women's school.Moreover,the biofeedback training group received Self-generate Physiological Coherence System training till one week before delivery.Both groups were evaluated with the EPDS at baseline,and 3 days,6 weeks,3 months postpartum.Differences between the two groups were compared with mixed effect model.Results Totally,there were 51 pregnant women finished the study,including 25 women in the biofeedback training group and 26 in the control group.There were no statistical difference in EPDS score at 12～14 gestational weeks between the biofeedback training group and control group [8.5±2.0 vs 8.5±1.9,t=0.03,P=0.97].At 3 days,6 weeks and 3 months postpartum,the EPDS score of biofeedback training group was 4.1 ± 1.8,4.7 ± 2.0 and 4.6 ± 1.8 respectively,which was lower than those in the control group (6.5 ± 2.4,7.0 ± 2.5and 6.9±2.4) (interaction effect F=4.35,P=0.01).On each postpartum time-point,OR value and 95％CI was 0.12 (0.03-0.45),0.21 (0.06-0.68) and 0.23 (0.07-0.77),P＜0.05 respectively.Cohen's d value were 1.17,0.99 and 1.06 respectively.Compared with the baseline value,the total EPDS scores in each study stage declined with varied degrees in both groups,and the score-reducing level were obvious in the biofeedback training group than in the control group.Conclusion Biofeedback training could effectively relieve the depression symptoms in pregnant women with high risks of postpartum depression,and decrease the risk of postpartum depression.

Objective To investigate the relationship between the genotype and phenotype of erythropoietic protoporphyria (EPP) in a family.Methods Venous blood samples were collected from two patients with EPP as well as their asymptomatic parents and grandmother.PCR was performed to assess the mutation of FECH gene,and real-time quantitative PCR to detect the expression of FECH gene.Results A mutation IVS3 + 1G ＞ A was detected in the two patients and their mother.Haplotype analysis showed that both patients with photosensitivity carried the wild-type low-expressed allele IVS3-48C,while their mother,the asymptomatic carrier,harbored the normal allele IVS3-48T.As real-time PCR showed,the expression intensity of FECH gene gradually increased from patients,asymptomatic patients to normal individuals.Conclusion The difference in expression intensity of FECH gene may contribute to the variability in clinical presentation of EPP.

Objective To analyze the mutations in nucleotide sequences of transfusion transmitted virus(TTV) in neonatal infection.Methods Neonatal serum TTV-DNA was detected by a nested PCR technique.Fifteen Chinese neonates with positive TTV-DNA were diagnosed as TTV infection.ORF1 sequences of TTV-DNA from these neonates were determined.Results Homology of Chinese TTV(C01-C15) and Japanese TTV(N22)isolated ranged from 87.1%-97.7% at nucleotide level,but there were point mutations in Chinese TTV,such as GG→TT in locus 112 and 113,TTATC→CCTAT in locus 236-240.Conclusions Chinese and Japanese TTV isolated had the same genotype.Some gene mutations may increase the TTV pathogen,and result in neonatal hepatitis syndrome or hyperbilirubinemia.

Objective To investigate the protective effects of recombinant human erythropoietin(rhEPO)treatment on histopathologic changes seen in hyperoxia induced lung injury.Methods Rat pups were randomly divided into four groups:Ⅰ:air-exposed control group,Ⅱ: air-exposed+rhEPO-treated group,Ⅲ:hyperoxia-exposed control group,Ⅳ:hyperoxia-exposed+rhEPO-treated group.GroupⅢ and Ⅳ rats were exposed to 85% oxygen.GroupⅡand Ⅳ rats were received rhEPO (1 200 U/kg) subcutaneously on postnatal 0 day and 2 day.On postnatal 14 day,survival curve,measurement of body weight and lung weight,radical alveolar counts(RAC),microvessel count were compared,CD_ 31 and vascular endothelial growth factor(VEGF) were performed by immunostaining to assess hyperoxia-induced changes in lung morphology.Results Treatment of hyperoxia-exposed rats with rhEPO prolonged the survival and resulted in a significant increase in the weight gain of body and lung[(25.88?2.59) vs(18.8?3.93) P

Objective To investigate the effects of 1,25-dihydroxyvitamin D3[1,25(OH)2D3] on regulatory T cells(CD4+CD25+ Foxp3+ T cell)and airway inflammation in asthmatic rats. Methods Asthmatic models were established in 28 rats with ovalbumin as sensitinogen,and four groups were randomly divided(n=7).1,25(OH)2D3 was orally administered 1 h before challenge in treatment group 1,dexamethasone was subcutaneously injected 1 h before challenge in treatment group 2,both 1,25(OH)2D3 and dexamethasone were given 1 h before challenge in treatment group 3,while no medicine was administered 1 h before challenge in group 4(asthmatic control group).The levels of IL-4 and IL-10 in bronchoalveolar lavage fluid(BALF) were detected,the total cell numbers were obtained and the eosinophil count was performed.The ratios of Treg to CD4+ T cells in peripheral blood and spleen mononuclear cells were measured with flow cytometry,and the mRNA expression of IL-10 and Foxp3 in lung tissues was detected.Wistar rats without asthma were served as normal controls(n=7). Results There were significant differences between asthmatic control group and normal control group in each parameter.Compared with asthmatic control group,the total cell number and eosinophil count decreased,the level of IL-4 decreased and the level of IL-10 increased in BALF in treatment groups.The ratios of Treg to CD4+ T cells in peripheral blood and spleen mononuclear cells significantly increased,and the mRNA expression of IL-10 and Foxp3 in lung tissues increased in treatment groups compared with asthmatic control group.There was no significant difference between treatment groups and normal control group in each parameter. Conclusion Administration of 1,25(OH)2D3 increases the proportion of Treg and expression of Foxp3 mRNA in peripheral blood and spleen in asthmatic rats.1,25(OH)2D3 has a regulatory effect on Treg,and may serve as a potential therapeutic approach against asthma.
