Objective To explore the causes of readmission after prostatectomy for BPH and to discuss the treatment approaches. Methods A total of 106 cases who were eligible for the study were reviewed.47 cases had residual and recurrent adenoma;of these cases,42 underwent TURP and 5 open prostatectomy again.32 cases developed urethral stricture;of these cases 27 underwent transurethral cold knife incision plus electric resection of scar and 3 urethral orifice reconstruction and 2 suprapubic cystostomy.11 cases who had experienced bleeding after TURP underwent transurethral bladder washing and coagulating.7 cases had neuropathic bladder dysfunction;of these cases 2 underwent transurethral bladder neck circle muscle resection,3 intermittent self-catheterization and 2 suprapubic cystostomy.6 cases had prostatic cancer;of these cases 1 underwent radical prostatectomy,3 palliative TURP plus orchiectomy and 2 orchiectomy.2 cases had incontinence after TURP;of the 2 cases 1 used external collecting device and 1 was transfered to other hospital for surgery.1 case had abdominal incision hernia and then underwent hernia repair. Results Among 106 cases, 97 cases underwent operations and of them 84 (86.6%) cases achieved successful results.The follow-up time was 6 months to 15 years with a mean of 5 years and 8 months.9 cases with urethral stricture required regular urethral dilation after surgery.4 cases who had had unsuccessful surgery underwent suprapubic cystostomy.Other 9 cases did not undergo operations due to poor health and other reasons. Conclusions Correct preoperative diagnosis, rational surgical type and adequate intraoperative and postoperative management are key to preventing readmission. Transurethral surgery is most favorable treatment choice for readmitted patients after prostatectomy for BPH.

Bi-specific antibodies (BsAb) P210/MMC, P210/TNP and P40/CD3 were prepared with different approaches. Among 11 fusions, 7, 484 wells were planted, and 223 dual positive wells were obtained from 1, 111 growth wells, only five hybrid-hybridomas secreting BsAb were obtained, showing the difficulties to prepare BsAb. It was shown that bridge assay is very important for identification of the BsAb. Among 12 triomas secreting y and ? chains, only two had BsAb. Therefore, the frequency for y and ? to combine to BsAb was 16.7(2/12). BsAb(P210/TNP) with versatile adaptor could mediate cytotoxic effects on target cells of different cytotoxic agents conjugated with TNP.Moreover, BsAb(P40/CD3) could mediate cytotoxic effects of peripheral blood lymphocytes (PBLs) on target cells. With local injection, four times treatments could abolish the tumor xenografts in nude mice.

BACKGROUND: It is proposed that elevated serum homocysteine is an important independent risk factor for ischemic stroke (IS), and 5, 10-methylenetetrahydrofolate reductase (MTHFR) is the key enzyme for homocysteine metabolism. The relationship between genetic mutation of MTHFR and IS remains controversial.OBJECTIVE: To examine the association of hyperhomocysteinemia and two MTHFR gene polymorphisms with IS in Northwest Chinese population.DESIGN: Case-control study.SETTING: Department of Neurology, First Hospital Affiliated to Jilin University, and Department of Neurology, Xijing Hospital, Fourth Military Medical University of Chinese PLA.PARTICIPANTS: Ninety-seven consecutive patients with ischemic stroke (71 males and 26 females) treated between November 2001 and May 2002were recruited, who were diagnosed by CT scan or MRI in the Department of Neurology, Xijing Hospital, Fourth Military Medical University of Chinese PLA. The control group consisted of 94 subjects (58 males and 36 females) without history of ischemic stroke. All the subjects were free of intracranial hemorrhage, cancer, renal dysfunction, and none used multivitamins or estrogen.METHODS: Serum homocysteine was measured by fluorescence polarization immunoassay. Polymerase chain reaction-restriction length polymorphism (PCR-RFLP) method was employed to detect the genotype at the two sites of C677T and A1298C in MTHFR gene.MAIN OUTCOME MEASURES: Serum homocysteine levels and the genotypic frequency frequencies of the two mutations of MTHFR.RESULTS: The 677T allele frequency was 59.3% in IS patients and 44.7% in the controls, showing significant differences (P=0.006), but no difference in 1298C allele frequency was detected between the two groups (22.7% vs 19.7%, P > 0.05). Homozygous 677TT genotype was closely associated with hyperhomocysteinemie (P < 0.01). In multivariate logistic regression analysis,677T gene mutation and hyperhomocysteinemie were all associated with the IS, with an OR of 1.870 and 1.031 (P< 0.05), respectively.CONCLUSION: Hyperhomocysteinemie is a risk factor of IS, and C677T mutation significantly increases homocysteine levels, and serves also as an independent genetic risk factor of IS.

A 68?year?old female patient was admitted to the hospital for multiple masses in the mouth and lungs as well as on dorsal hands for more than 20 days without obvious subjective symptoms. No abnormalities were found by physical examination. Dermatological examination showed two bean?sized dark?red nodules on the upper jaw as well as one pigeon egg?sized dark?red nodule on the left dorsal hand, and all the nodules were hard with smooth surfaces and limited mobility. Positron emission tomography?computed tomography (PetCT) revealed multiple metastases to the brain, lymph nodes, lungs, gastrointestinal tract, both kidneys, multiple bones and intermuscular tissues. Pathology of nodules from the upper jaw showed lowly differentiated tumor cells with osteoid matrix, chondroid structures and tumor bone in local areas, and immunohistochemical examination of tumor cells found positive staining for S100(focally), vimentin, CD99, P63 and Ki?67(60%), but negative staining for keratin. A diagnosis of osteosarcoma of the right side of the upper jaw was considered. Pathology of nodules from the dorsal hand revealed no obvious abnormalities in the epidermis, while there was a diffuse infiltration of medium?to large?sized histiocyte?like cells in the whole dermis with cell atypia and irregularly red?stained bone matrix and tumor bone in some regions. Immunopathology showed positive staining for Ki67(60%), and negative staining for CD3, CD10, CD20, Bcl?2, and Bcl?6. A diagnosis of cutaneous metastasis of osteosarcoma was made. The patient refused further treatment and died 6 months after the onset of lesions.

The efficacy of Chinese herbal formula in treating depression has been proved in many studies. In this study, six different Kaixin San formulas were compared to investigate their effects on central monoamine neurotransmitters of chronic stress rats and against depression based on their different components in plasma, in order to discuss the efficacy-comparability relationship and the possible efficacy mechanism. The classic isolation method and the chronic unpredictable mild stress (CUMS) depression model were combined to investigate the changes in contents in hippocampus and monoamine neurotransmitters (NE, DA, 5-HT) and the components of some formulas in plasma with HPLC and UPLC-Q-TOF-MSE methods. As a result, Dingzhi Xiaowan recorded in Essential Recipes for Emergent Use Worth A Thousand significantly increased the behavioral scores, NE and 5-HT contents in hippocampus and NE, DA and 5-HT contents in cortex, with the best anti-depressant effect. Dingzhi Xiaowan recorded in Complete Records of Ancient and Modern Medical Works showed a notable increase in sucrose preference and open field score in model rats, NE content in hippocampus and NE, DA and 5-HT contents in cortex, with a certain anti anti-depressant effect. Kaixin San recorded in Ishinpo showed remarkable rise in weight of model rats. NE content in hippocampus and DA content in cortex. Puxin Decoction recorded in A Supplement to Recipes Worth A Thousand Gold showed 5-HT content in hippocampus and DA content in cortex. Kaixin San recorded in Yimenfang only showed DA content in cortex. Kaixin Wan recorded in Essential Recipes for Emergent Use Worth A Thousand did not mention the antidepressant effect. According to the results, the formulas' different anti-depressant effects may be related to the different plasma components.
