Expression of CBX8 in gastric adenocarcinoma and the relationship with clinicopathologic characters and survival prognosis / 临床与实验病理学杂志

Purpose To explore the expression of CBX8 in gastric adenocarcinoma tissue and its clinical significance.Methods 119 cases of primary gastric adenocarcinoma treated by surgery and corresponding adjacent normal tissues were collected. The protein expression levels of CBX8 in gastric adenocarcinoma and their corresponding adjacent normal tissue was determined using tissue microarray and immunohistochemistry PV 6000 method staining. The relationship between CBX8 expression and clinicopathologic characters and survival prognosis was analyzed. Results The positive expression rate of CBX8 in gastric cancer and their corresponding adjacent normal tissue was 46.2％ (55/119) and 13.4％ (16/119) respectively. There was statistically significant difference between two groups (χ2=30.53, P < 0.01). The expression of CBX8 in gastric adenocarcinoma tissue was obviously correlated with the differentiation, clinical staging, and lymph node metastasis (P < 0.05). The high expression rate of CBX8 in the poorly differentiated gastric adenocarcinoma was lower than moderately differentiated and well differentiated group. The high expression rate of CBX8 in stage Ⅰ + Ⅱ gastric adenocarcinoma was higher than that in stage Ⅲ + Ⅳ. The gastric adenocarcinoma patients with high expression of CBX8 had low metastasis rate. Cox multivariate analysis showed CBX8, clinical staging, and lymphatic metastasis were independent predictors of overall survival and disease-free survival (P < 0.05). Kaplan-Meier analysis showed that the patients with higher expression of CBX8 had both longer overall survival time (P = 0.004) and disease-free survival time (P =0.004). Conclusion The expression of CBX8 may be involved in the tumorigenesis and progression of gastric adenocarcinoma. CBX8 is one of the independent predictor of prognosis, and the detecting of CBX8 expression may have important clinical value for the evaluation of gastric adenocarcinoma. CBX8 may became a new target for target therapy of gastric adenocarcinoma.

Doença de Haff complicada por falência de múltiplos órgãos após ingestão de lagostim: estudo de caso / Haff disease complicated by multiple organ failure after crayfish consumption: a case study

A doença de Haff é uma síndrome que consiste de rabdomiólise não explicada. Pacientes que apresentam a doença de Haff relatam ter ingerido pescado nas últimas 24 horas antes do início da doença. A maioria dos pacientes sobrevive apresentando breve recuperação. O presente artigo é o primeiro relato de doença de Haff complicada por falência de múltiplos órgãos após ingestão de lagostim. Um homem chinês de 66 anos de idade ingeriu lagostim cozido na noite de 23 de junho de 2013. Chegou ao hospital 2 dias mais tarde, sendo admitido à unidade de terapia intensiva. Após a admissão, o paciente recebeu o diagnóstico de doença de Haff complicada por falência de múltiplos órgãos. Apesar dos tratamentos de suporte e sintomático, a condição do paciente deteriorou, vindo o mesmo a falecer em consequência da doença. A doença de Haff é uma rara síndrome clínica que é, às vezes, mal diagnosticada. O diagnóstico precoce e o tratamento adequado são essenciais para prevenir a progressão para falência de múltiplos órgãos.

Haff disease is a syndrome consisting of unexplained rhabdomyolysis. Patients suffering from Haff disease report having eaten fish within 24 hours before the onset of illness. Most patients survive and recover quickly. The present study is the first report of Haff disease complicated by multiple organ failure after crayfish consumption. A 66-year-old Chinese man ate cooked crayfish on the night of June 23, 2013. He arrived at our hospital 2 days later and was admitted to the intensive care unit. After admission, the patient was diagnosed with Haff disease complicated by multiple organ failure. Despite supportive and symptomatic treatments, the condition of the patient deteriorated, and he died due to his illness. Haff disease is a rare clinical syndrome that is sometimes misdiagnosed. Early diagnosis and proper treatment are essential to prevent progression to multiple organ failure.

Clinical application of xenogenic (porcine) acellular dermal atrix (ADM) in scar treatment / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the role of xenogenic (porcine) ADM as dermal substitute in scar treatment.</p><p><b>METHODS</b>After scar excision, the wounds were covered with composite grafts of DR procine ADM and autologous thin split-thickness grafts in one stage or in two stages.</p><p><b>RESULTS</b>22 out of 47 cases were treated in two-staged procedure. After the ADMs were applied to the wound, the autologous thin split-thickness grafts were implanted 7 days later. 25 cases were treated in one-staged procedure. The survival rates of composite grafts were (88.3 +/- 3.7)% for subcutaneous recipient bed and (89.7 +/- 3.4)% for deep fascia recipient bed in group with two-staged procedure, compared with (92.5 +/- 4.1)% and (93.2 +/- 5.2)%, respectively, in group with one-staged procedure. Early after grafts taken, the grafts had a pink colour and smooth surface. The patients were followed up for 90 days at most. The survived composite grafts were durable, elastic, smooth and soft with good function and appearance like normal skin. They could even be pinched up. The scar along the edge of the grafts was slightly hypertrophic.</p><p><b>CONCLUSIONS</b>The survival rate of composite graft is higher in patients with one-staged procedure. The elasticity and textural of the taken grafts are better on subcutaneous recipient bed than on deep fascia recipient bed, though the function has no difference. Xenogenic (porcine) ADM can be an optimal dermal substitute for wound coverage after scar excision.</p>

Preliminary experience in treatment of chronic prostatitis/chronic pelvic pain syndrome with Longjintonglin capsule / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the effectiveness of Longjintonglin capsule in treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).</p><p><b>METHODS</b>One hundred and thirty-six patients accorded with the demands of chronic prostatitis type III of National Institute of Health (NIH), among them there were 84 cases of chronic prostatitis type IIIA and 52 cases of type IIIB. All of the patients accepted oral Longjintonglin capsule for 3 tablets, 3 times per day, for 3 months. NIH- chronic prostatitis symptom index (NIH-CPSI) and counting leukocytes in expressed prostatic secretions (EPS) were used as target to evaluate the effectiveness.</p><p><b>RESULTS</b>One hundred and thirty-one cases accomplished treatment, in which there were 81 cases of type IIIA, and 50 cases of type IIIB. Overall scores of NIH-CPSI before and after treatment were(24.8 +/- 5.6) and (13.3 +/- 6.8) points respectively, which dropped significantly (average 11.5 points), (P < 0.01). The symptom scores before and after treatment were (15.4 +/- 4.3) and (8.7 +/- 3.9) respectively, which also decreased significantly (average 6.7 points), (P <0.01). The scores for quality of life before and after treatment were (9.4 +/- 3.7) and (4.6 +/- 2.7) respectively, which dropped significant (average 4.8 points) (P < 0.01). The leukocytes counts before and after treatment in patients with CP/CPPs type IIIA were (21.7 +/- 14.5)/HP and (8.8 +/- 12.6)/HP, respectively. Twenty-four cases(18.3%) got cured, 41 cases (31.3%) notable effect, 40 cases (30.5%) some effect, 26 cases (19.8%) no effect, and total effective rate was 80.1%. No apparent side effect was observed in all patients accepted treatment, especially for their kidney and hepatic function.</p><p><b>CONCLUSION</b>Longjintonglin capsule was a safe and effective medicine in treatment of CP/CPPS without significant side effect.</p>

Treatment of deep partial thickness burns by a single dressing of porcine acellular dermal matrix / 中华外科杂志

<p><b>OBJECTIVE</b>To explore the effect of one dressing of porcine acellular dermal matrix on deep partial thickness burns.</p><p><b>METHODS</b>From January 1997 to January 2004, sixty-seven cases of deep partial thickness total burned surface area (TBSA) from 50% to 90% burn wound were treated by a single dressing of porcine acellular dermal matrix (the porcine acellular dermal matrix group). Ten cases of deep partial thickness burned patients with the same TBSA treated by exposure method served as the exposure method group. The healing time of the wound was observed. The patients were followed up for 3 months to 2 years, and the scar proliferation was observed.</p><p><b>RESULTS</b>The deep partial-thickness wound would be healed without dressing change in the porcine acellular dermal matrix group, and the average healing time was (12.2 +/- 2.6) days. The average healing time of the exposure method group was (27.4 +/- 3.5) days. Follow up of the patients within 3 months to 2 years showed that scar proliferation in the porcine acellular dermal matrix group was much less than that in the exposure method group, even no scar proliferation was observed in some patients.</p><p><b>CONCLUSION</b>Without tangential excision, autografting and dressing change, a single dressing of porcine acellular dermal matrix on deep partial thickness burn wound could shorten the healing time and inhibit scar proliferation.</p>
