1.Research progress on PD-1/PD-L1 inhibitors in prostate cancer immunotherapy
Chinese Journal of Clinical Oncology 2017;44(16):831-834
The annual incidence of prostate cancer (PCa) continually increases. New PCa immune therapy has become the fourth line antitumor treatment following surgery, radiotherapy and chemotherapy. As the most promising research direction in cancer immunotherapy,immune checkpoint inhibitors, such as programmed cell death-1 and programmed cell death-ligand 1 (PD-1/PD-L1) inhibitors, block PD-1 and its ligand PD-L1 and then terminate the negative control signal to the T cell, thereby facilitating T cell recovery and reversal of tumor immune-escaping mechanism. These processes restore the capability of T cells for immune response and inhibit and kill tumor cells. This review summarizes the progress on the current application of PD-1/PD-L1 inhibitors in PCa clinical trials.
2.THYROGLOBULIN ANTIBODY PRODUCTION BY CULTURED PERIPHERAL BLOOD MONONUCLEAR CELLS FROM PATIENTS WITH AUTOIMMUNE THYROID DISEASE
Chinese Journal of Endocrinology and Metabolism 1985;0(02):-
Thyroglobulin antibody (TGA) production in vitro by cultured peripheral blood mononuclear cells (PBMC) from patients with autoimmune thyroid disease (AITD) was measured by ELISA technique. PBMC from patients with AITD could synthesize and secret detectable amount of TGA. The average positive rate of TGA production in vitro was 31.25%. PBMC from the patients with Hashimoto thyroiditis (HT) could produce TGA more easily than that from the patients with Graves'disease (GD). The average positive rate was 44.19% in HT and 16.22% in GD. Pokeweed mitogen could increase TGA production, but soluable thyroglobulin could not stimulate TGA synthesis and secretion. Antithyroid drug methi-mazole had some inhibition effect on TGA production in vitro. A significant positive correlation between the serum TGA and the amount of TGA produced in vitro by PBMC from HT patients (r = 0.4, P
3.THE EFFECT OF CHRONIC LITHIUM. ON CALMODULIN ACTIVITY IN RAT BRAIN
Journal of Chongqing Medical University 1986;0(04):-
Lithium(Li) salt is. a kind of effective drug commonly used in the treatment and prevention of mental disorders, but its active mechanism is still not well understood. Getting on for twenty years, many research have been reported on relationship between Li salt and second messenger system, especially the effect of Li salt on adenylate cyclase. Identical result is not obtained and there are few reports on brain calmodulin (CaM) activity change by Li salt. The aim of present expcri- ment is to determine the content of CaM in raet brain by phosphodiesterase (PED) method after chronic application of Li salt and discuss preliminary the molecular mechanism of Li salt action. The result showed that marked change has happened in the content of CaM in rat brain after chronic application of Li salt. It is ins-plied that Li salt brings its action into play probably by changing the content of CaM in rat brain

Chinese Journal of Applied Clinical Pediatrics 2016;31(23):1803-1805
Objective To investigate the clinical characteristics,treatment options and prognosis of duplex kidneys in children.Methods Data were retrospectively collected from all patients who were hospitalized at Shengjing Hospital Affiliated to China Medical University from January 2008 to May 201 5.The surgery to retain moie-ty nephron was performed in 30 cases:1 2 cases underwent non common sheath ureter reimplantation,4 cases of the patients had common sheath ureter reimplantation,1 2 patients underwent transurethral resection of the cyst,1 case of them had pyeloureterostomy,and the other patients underwent lower -pole pyeloplasty.Removal of renal moiety was performed in 52 cases:43 patients underwent upper -pole heminephrectomy,8 patients underwent upper pole hemi-nephrectomy and lower -pole ureter reimplantation,and 1 case of the patients had upper -pole heminephrectomy and lower -pole ureteroplasty.Results A total of 54 cases were followed up,the follow -up rate reached 65.9%,the follow -up time lasting 2 months to 4 years,with an average time of 9.53 months.All clinical symptoms disappeared after remove moiety operation.There were small ureteral cysts but compared with the preoperative condition,the symp-toms reduced significantly in 4 cases.All clinical symptoms disappeared in patients whose nephron was retained after operation,and hydronephrosis was alleviated.De novo 2 degree of vesicoureteral reflux was found in 3 out of 1 2 pa-tients who underwent transurethral puncture of the cyst.Conclusions The clinical manifestations of duplex kidney have some characteristics which include recurrent urinary tract infection,normal intermittent voiding urine dripping, abdominal pain,urethral orifice mass,abdominal mass and aggravation of hydronephrosis.Duplex kidney is often asso-ciated with cardiac malformation and cryptorchidism.The preoperative testicular examination and echocardiography should be performed.The choice of operation depends on the clinical manifestation,auxiliary examination results and comprehensive analysis.The prognosis of duplex kidney is well,but patients need to be further followed up af-ter operation.
6.Vascular anatomy and evaluation of the nipple-areola complex in nipple-sparing mastectomies
China Oncology 2016;26(5):372-377
Nipple-areola complex (NAC)-sparing mastectomies (NSM) have gained acceptance in the ifeld of breast oncology. The superior aesthetic outcomes of NSM explain their increased use and rising popularity. Technical considerations and challenges of this procedure are centered on nipple ischemia and necrosis. Patient selection, reconstructive strategies and incision placement have lowered ischemic complication rates. An understanding of the NAC vascular anatomy is, therefore, clinically relevant beyond NSM. In this paper, the relevant clinical anatomy is described, mainly focusing on the anatomy of the NAC. This article also covers how to identify and classify the in vivo blood supply to the NAC using breast MRI exams which provide valuable information for assessing vascular anatomy of the NAC. This includes the arterial iflling phase, venous drainage phase and 3-dimensional reconstructed maximum intensity projection (MIP) images. Finally, the indocyanine green (ICG) and a specialized infrared camera-computer system provide surgeons with a practical tool to assess real-time breast skin and NAC perfusion. Intraoperative evaluation of skin perfusion allows surgeons to detect ischemia and modify the operative approach to reduce the risk of nipple ischemia and necrosis.

Chinese Journal of Rehabilitation Theory and Practice 2016;22(9):1045-1048
Objective To observe the effects of Kinesio taping on upper limb spasticity after stroke. Methods From March to Novem-ber, 2015, 39 stroke patients were divided into Kinesio taping group (Kinesio taping and rehabilitation, n=13), white taping group (white tap-ing and rehabilitation, n=13) and blank group (rehabilitation, n=13) randomly. They were evaluated with modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA) of upper limbs and the modified Barthel Index (MBI) before treatment, four and eight weeks after treat-ment. Results There was no significant difference among the three groups in the scores of FMA and MBI (P>0.05) four weeks after treat-ment, but the score of MAS improved more in the Kinesio taping group than in the other two groups (P<0.05). The scores of MAS, FMA and MBI all improved more in the Kinesio taping group than in the other two groups (P<0.05) eight weeks after treatment. Conclusion The application of Kinesio taping can relieve upper limb spasticity, and improve motor function and activities of daily living for patients with stroke.
