ObjectiveTo evaluate the therapeutic effect of phacoemulsifcation and posterior chamber intraocular lens(IOL) implantation combined with trabeculectomy in patients with cataract and glaucoma.Methods26 cases(26 eyes)were theated by phacoemulsification and IOL implantation combined with trabeculectomy.Follow-up period was for 2～16 months.ResultsThe average intraocular pressure(IOP)was reducded from 24.82 mmHg preoperatively to 16.52 mmHg postoperatively.IOP was less than 21 mmHg in 88.46% eyes.Visual acuity was 0.3 or better in 80.77% of eyes during following-up.61.54% of eyes were found with functional filtering blebs.ConclusionTriple procedure is safe and suitable method for most patiants with glaucoma and cateract

ObjectiveTo investigate the influence of internal sphincter deletions on postoperative fecal incontinence in rectal cancer patients after intersphincteric resection (ISR). MethodsSeventy one cases of rectal tumour were respectively treated by low anterior resection (group A, intact internal sphincter),partial ISR (group B,1/3 internal sphincter deletion),subtotal ISR (group C,2/3 internal sphincter deletion) and total ISR (group D,total internal sphincter deletion).Anorectal manometry and Vaizey scoring system were used to trace dynamic changes of fecal incontinence in the four groups in one year follow up. Data were analyzed with repeated-measures analysis of variance and multivariate analysis of variance. ResultsIn all cases the length of postoperative anal high-pressure zone shortened by groups.With time the length of high-pressure zone increased slightly.By the end of postoperative 12 months,there were still significant differences between groups( F =41.873,P =0.000).The maximum resting pressure of anal canal significantly reduced in all groups.By the end of postoperative 12 months,it almost restored to preoperative level in group A,while in group B and C it was about 2/3 of the preoperative level; and 1/3 of the preoperative level in group D.Vaizey score at postoperative 10 days,increased in all groups.In group B and C the score was on continuous decrease until the end of postoperative 12 months(P =0.158) it was close to that in group A.While in group D it was only 13.7 ±3.2 by the end of postoperative 12 months.Multiple regression analysis showed that by the end of postoperative 12 month,the maximum resting pressure of anal canal and postoperative anal high-pressure zone length were significantly and negatively related with the subjective Vaizey score of fecal incontinence ( t =- 4.802,P =0.000 ; t =- 2.011,P =0.048 ).ConclusionsIn patients of ultra-low rectal cancer undergoing intersphincteric resection,fecal incontinence severity indicator vaizey score as evaluated by the end of postoperative 12 months was associated with the maximum resting pressure of anal canal and anal high-pressure zone length.In addition,postoperative fecal incontinence severity carries reversible dynamic changes, and with time, most patients could restore satisfactory stool control function.

A bacterium which can effectively degrade LAS (Linear Sodium Alkylbenzenesulfonate) was isolated from washing powder manufacturing effluent and was preliminarily identified as Corynebacterium jeikeium GZ6. The bacterium can degrade LAS up to till 700 mg/L, and the optimum pH, temperature and concentration of LAS are 7.0, 30℃ and 400 mg/L, respectively. The biodegradation rate can reach 98.7% after 24 hours'cultivation in the suitable conditions. Experiments also showed that some heavy metal ions such as Hg2+ , Co2+ , Cd2+ can differently inhibit the degradation of LAS.

OBJECTIVE: To assess the clinical effect of bucillamine in rheumatoid arthritis (RA), we performed an open clinical trial for 3 months. METHODS: 10 out of 12 patients completed bucillamine trial(200mg/day) for their initial treatment against arthritis, and 9 out of 11 patients with refractory RA completed the bucillamine trial. Disease activity was assessed by the duration of morning stiffness(MS), visual analogue pain scale(VAPS), functional capacity(FC), tender joint counts(TJC), swollen joint counts(SJC), ESR, and CRP every month. Adverse effects were monitored monthly. RESULTS: At the end of trial, all parameters were decreased in the initial treatment group except of CRP. No parameters were decreased in the refractory group. Gastrointestinal disturbance was the most commmon adverse effect. Skin rash, stomatitis, proteiuria and elevated hepatic enzyme were minor adverse effects. CONCLUSION: Bucillamine was effective in the initial treatment of rheumatoid arthritis, but not effective in the patients with refractory rheumatoid arthritis. Bucillamine is relatively safe in the treatment of rheumatoid arthritis in both groups.

Various anatomical defects have been described in the surviving co-twin who had stillborn, macerated monozygotic co-twin with disseminated intravascular coagulation. The suggested mechanism was the transfer of emboli or thromboplastic materials of dead fetus to co-twin through placental vascular anastomoses. Multicystic encephalomalacia is the condition defined anatomically by the presence of multiple cavities in the great part of both cerebral hemispheres. The most common pathogenesis is circulatory disturbance caused by neonatal asphyxia during the perinatal period. We experienced two cases of monozygotic twin with deceased co-twin at 26 weeks, 33 weeks of gestation and confirmed the diffuse multicystic encephalomalacia by cranial ultrasonography and MRI in a surviving co-twin. Only one patient has been followed who showed spastic cerebral palsy and severe mental retardation. We report two cases of multicystic encephalomalacia in a surviring co-twin with a intrauterine fetal death and its related literatures.

The third complementarity determining region (CDR3) of the immunoglobulin (Ig) kappa () chain is known to be located at the center of antigen binding groove and critical for antibody specificity. Ig chain has been characterized by limited junctional diversity due to the absence of N-region addition resulting in relative conservation of CDR3 lengths with 9 or 10 amino acids. CDR3 region of 11 amino acids is only possible with N-region addition. Recently, x transcripts with 11 amino acids CDR3 was found to be expressed in normal individuals, and in autoimrnune disease such as rheumatoid arthritis, the fraction of 11 amino acids CDR3 of humkv325-derived chains was overexpressed compared to conventional adult peripheral B cells. However, the significance of this bias is difficult to interpret without a clear understanding of normal repertoire of CDR3 length during development. The purpose of this study is to determine whether developmental regulation of CDR3 amino acids codon lengths exists in chains expressed in the fetal liver, cord blood, and adult peripheral blood lymphocytes (PBL). Lymphocytes were seperated from fetal liver, cord blood and adult PBL and cDNA was generated from extracted mRNA. PCR-based CDR3 finger- printing assay was performed with VI-IV family specific primers. CDR3 length diversity of Ig x chain increases as the development proceeds. The length diversity most frequently occured in Vlll family derived transcripts including 11 amino acids CDR3. transcripts with 11 amino acids CDR3 were consitently expressed in both fetal and adult Ig repertoire. These results support the hypothesis that v chain CDR3 length is developmentally regulated and implicates the diversity of antigen-antibody specificity generation.

Objective To summarize the clinical experience of interspineter resection in treating ultra-lower rectal tumor. Methods Twenty-six ultra-lower rectal tumor cases (24 cases of rectal cancer, 2 cases of giant villous adenoma) without extrasphincter involvement underwent total mesoreetal excision and interspineter resection. Partial, subtotal or total innerspineter resection was performed respectively for patients in which the tumor lower margin was over 2 cm, between 1 -2 cm, and less than 1.0 cm above thedentate line respectively. Alimentary tract continuity was constructed by end to end anastomsis of the colon and anus. Results The lower margin of tumor in 26 patients was within 0 - 3 cm above the dentate line.The pathology was highly differentiated in 6 cases and medium differentiated in 16 cases, papillary carcinoma in 2 cases, giant villous adenoma in 2 cases. There were 11 cases of stage Ⅰ , 8 of stage Ⅱ A, 4 of stage Ⅲ A, and 1 of stage Ⅲ B according to pTNM system; 8 cases of T1, 15 of T2, and 1 of T3 according to T stage criteria. There was no mortality nor major complications. Two cases suffered from anastomotic stricture. The stool seepage was common at early stage after surgery, with immediately postoperative daily defecation of 3 -10, and one year later, most patients were able to hold back the defecation impulse for more than 5 min, and have daily defecation of 0. 5 to 4 times. Occasional seepage was reported in one patient with total innersphincter resection. The average postoperative follow up was 28 months. One recurrence was found on the 5th month, one suffered from liver metastasis in the 10 month, and one died of cardiac arrest in 26 month. Conclusion To those patients with very lower rectal cancer restricted within rectal wall,interspincter resection fulfils curative purpose while preserving the anal function.
