Objective To investigate the monocyte chemoattractant protein (MCP1) gene expression of the bladder urothelial carcinoma and its correlation with the pathogenesis of the bladder urothelial carcinoma.Methods Thirty cases of patients with the bladder urothelial carcinoma, including 20 cases of male and 10cases of female, were taken the blood and bladder tissue.In control group, 30 cases of non-cancer patients,including 20 cases of male and 10 cases of female, were taken the blood samples.ELISA method was used to detected the concentration of plasma MCP1, immunohistochemical method to investigate the expression of MCP1 in the bladder urothelial carcinoma and adjacent tissues.Real-time quantitative RT-PCR was applied to detected the expression of MCP1. Data of the two groups were comparied and the relationship between the expression of MCP1 and the clinical characteristics of the bladder urothelial carcinoma was analyzed.Results MCP1 in group of patients with the bladder urothelial carcinoma was (193.4±105.7) pg/ml, and higher than that in non-tumor group (91.8±34.6) pg/ml (t = 8.37, P <0.001).MCP1 in invasive bladder cancer was (204.3±167.5) pg/ml and superficial bladder cancer was (130.6±69.2) pg/ml (t = 2.667, P = 0.013). By immunohistochemistry, the MCP-1 positive rate in the bladder urothelial carcinoma was 70.0 % (21/30), that in adjacent cancer tissue was 43.3 % (13/30) (χ2 = 4.9, P <0.05). The positive rate of MCP1 in invasive bladder cancer in tumor group was 80.0 % (8/10) and that in superficial bladder cancer was 65.0 %(13/20).At the same time, MCP- 1 positive intensity in the bladder urothelial carcinoma was significantly higher than that in adjacent tissues. The intensity in invasive bladder cancer was higher than that in superficial ones. Total RNA and mRNA levels of MCP-1 in the bladder urothelial carcinoma were statistically differences compared with that in adjacent tissues (χ2 = 10.08, P <0.05).Conclusion The upregulation of MCP1 gene expression is likely to play an important role in the incidence and metastasis of the bladder urothelial carcinoma.

ObjectiveTo evaluate the laparoscopic procedure and therapeutic efficacy of retroperitoneal laparoscopic surgery for the treatment of adrenal ganglioneuroma.Methods6 patients [4 male and 2 female,32 to 59 (mean 41.3) years old],underwent retroperitoneal laparoscopic resection of adrenal ganglioneuroma. In this group, 2 patients with left adrenal ganglioneuroma, 4 patients with right adrenal ganglioneuroma. ResultsAll of the 6 cases was successfully performed uneventfully with retroperitoneal laparoscopic adrenalectomy. Pathologic studies confirmed there were 6 cases of adrenal ganglioneuroma. No case was transferred to open operation.The blood pressure remained stable during operation.Mean tumor size was (5.9±2.1) cm (tumor diameter 3.6-11.2 cm) Mean operative time was 120(90-210) min.Mean estimated blood loss was 160 (50-700) ml.Postoperative hospital stay ranged from 7 to 9 days.All the patients were cured without relapse during 4-32 month, follow-up. ConclusionsRetroperitoneal laparoscopic procedures for adrenal ganglioneuroma causes less traumatic;less operative blood loss;distinct image during operation;less postoperative discomfort;faster postoperative recovery and earlier return to daily activities and diet.Retroperitoneal laparoscopic procedure should be considered as the first choice for adrenal ganglioneuroma.
4. Effect of adductor canal block combined with local infiltration anesthesia on rehabilitation of primary total knee arthroplasty
Chinese Journal of Reparative and Reconstructive Surgery 2018;32(8):1006-1011
Objective: To investigate the effect of adductor canal block combined with local infiltration anesthesia on the rehabilitation of primary total knee arthroplasty (TKA). Methods: A total of 104 patients who met the selection criteria for the first unilateral TKA between March 2017 and August 2017 were included in the study. They were randomly divided into trial group (53 cases) and control group (51 cases). In the trial group, the adductor canal block with intraoperative local infiltration anesthesia were performed. In the control group, only intraoperative local infil-tration anesthesia was performed. There was no significant difference in gender, age, body mass index, diagnosis, effected side, and the preoperative American Society of Anesthesiologists (ASA) grading between 2 groups ( P>0.05). The operation time, length of stay, and complications were compared between 2 groups, as well as visual analogue scale (VAS) score of incision at rest and during activity, the range of motion (ROM) of knee flexion and extension activity, limb swelling (thigh circumference), walking distance, and pain VAS score while walking. Results: The operation time of the trial group was significantly shorter than that of the control group ( t=-2.861, P=0.005). However, there was no significant difference in length of stay between 2 groups ( t=-0.975, P=0.332). The wound effusion occurred in 1 patient of trial group and 2 of control group; hematoma occurred in 2 patients of trial group and 3 of control group; no symptom of intermuscular venous thrombosis occurred in 1 patient in each of 2 groups; ecchymosis occurred in 14 patients of trial group and 15 of control group; there was no significant difference in the incidence of related complications between 2 groups ( P>0.05). There was no significant difference in the preoperative VAS score at rest and during activity, ROM of knee flexion and extension activity, and thigh circumference between 2 groups ( P>0.05). However, there were significant differences in the VAS score at rest and during activity after 2, 4, 8, and 12 hours, ROM of knee flexion and extension activity after 1 and 2 days, and the walking distance on the day of discharge, pain VAS scores while walking after 1 and 2 days and on the day of discharge, and thigh circumference after 1 day between 2 groups ( P<0.05). Conclusion: For the primary TKA, the adductor canal block combined with local infiltration anesthesia can early relieve the initial pain of the incision, shorten the operation time, and promote the mobility and functional recovery of the knee joint.
5.Analysis of polymorphic markers by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
Chinese Journal of Medical Genetics 2005;22(2):185-188
With the development of genomics and the accomplishments of human genomic sequencing, polymorphic markers and their analytic approaches are more and more important, and much attention has been paid to the fact that the analysis of single nucleotide polymorphisms utilizing matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF MS) is a high-throughput approach. MALDI-TOF MS can also mini-sequence and genotype short tandem repeat. The approaches to analyzing single nucleotide polymorphisms are primer oligonucleotide base extension, ligase reaction, peptide nucleotide acid, invader assay, and so on.

Chinese Journal of Medical Genetics 2002;19(5):420-424
Chromosome Y does not recombine with any other at meiosis except that on pseudoautosomal region. Polymorphic markers on the chromosome Y are paternal inheritance and are haploidly inherited. Variance of the sequences comes from accumulated mutation. These properties make them unique and important not only to anthroponomy and genetics but also to forensic science and medicine.

7.Genetic polymorphisms, function and clinical effect of HLA-G.
Chinese Journal of Medical Genetics 2002;19(4):350-353
HLA-G is a non-classical major histocompatibility complex class I molecule that differs from the classical HLA I class molecules by (1) a limited polymorphism, (2) a tissue-restricted distribution and (3) a transcription of spliced messenger RNAs encoding for at least four membrane-bound and two soluble HLA-G isoforms. Extensive studies over the past few years have identified HLA-G as a molecule involved in immune tolerance. In this review, attempts were made to summarize the current state of knowledge of the polymorphisms, expression, function, the effects of HLA-G on immuno-associated disease, evolution of HLA-G and its utility in disease therapy.

8.Relationship between HFE gene and hereditary hemochromatosis.
Chinese Journal of Medical Genetics 2002;19(2):159-162
HFE gene is a major histocompatibility complex class I-like gene, which was identified as a candidate gene for hemochromatosis in 1996. The proposed role for HFE is its part in the regulation of the interaction of the transferrin receptor with transferrin. Hemochromatosis, the common autosomal recessive disease of iron overload, affects at least 1 in 300 Caucasians. The identification of the C282Y mutation in the HFE gene has led to population screening studies. Much of this work has also included the analysis of a second mutation, H63D, which appears to have a low penetrability. HFE protein was recently found to coprecipitate with the transferrin receptor and to affect the reaction between transferrin and the transferrin receptor. Functional data suggest that the mutation C282Y abolishes the association of the HFE protein with beta 2-microglobulin (beta 2M), making the complex unable to reach the cell surface. Clearly, if the mutation protein is unable to reach the cell surface, this regulatory feature is missing. The role of a second mutation in the HFE gene, H63D, is less clear. Current data suggest that this mutation protein can associate with beta 2-microglobulin and does reach the cell surface and that the defect lies in a failure to modify the affinity of the transferrin receptor for transferrin. This does not explain the low degree of penetrability associated with this mutation.

Wei-wei ZHAO ; Peng XIE ; Hou-fu DENG
National Journal of Andrology 2010;16(3):269-272
Strontium-89 (Sr-89) is a pure emitter with maximum beta energy of 1.46 MeV, average beta energy of 0.58 MeV, and a physical half-life of 50.5 days. It is rapidly taken up by bone and preferentially retained at the sites of osseous metastases. Its biological half-life is >50 days at the metastatic sites, but about 14 days only in the normal bone. The dose of its absorption in the tumor-bearing bone ranges from 21 +/- 4 to 231 +/- 56 cGy/MBq, 2-25 times higher than in the normal bone. Strontium-89 therapy is an effective palliative treatment of bone metastases from prostate cancer, with analgesic effectiveness in 80%.

Vincristine is a dimer-indo-alkaloid which is extracted from the leaves of Catharanthus roseus. It is effective to treat acute lymphocytic cell leukemia, Hodgkin disease and non-Hodgkin disease clinically. But the severe side effects, such as neurotoxic and tissue damage, limit its application. In this paper, we summarize physical, chemical, pharmacological and pharmacokinetical properties of VCR and advances in decreasing its side effects. In clinic, association with other medication is adopted. In pharmaceutics, people adopt some new methods and technology such as conjugation with the antibody, encapsulation in liposomes or controlled release films.
