3.Diagnosis of intracranial malignant melanoma.
Chinese Journal of Surgery 2004;42(13):784-786
OBJECTIVETo analyse the diagnosis points of intracranial malignant melanoma.
METHODSThere were ten patients with intracranial malignant melanoma (but without clear extracranial primary lesion), whose epidemiology, clinical symptom, physical sign and imaging data were analysed.
RESULTSMost of patients were young men, The Clinical symptom or physical sign are similar to brain tumor or cerebral hemorrhage, but the course was shot, two cases of among having skin melanotic nevus. As for most of cases, CT were high density, MRI T1WI showed high signal and T2WI low signal, which often had hemorrhage. Histological examination showed all cases were malignant melanoma. Preoperative misdiagnosis was up to eight cases (80%).
CONCLUSIONSFor preoperative accurate diagnosis, this disease's epidemiology, clinical symptom, extracranial physical sign and imaging data points could be synthetical analysed.

OBJECTIVETo investigate the role of endogenous hydrogen sulfide (H2S) in erectile dysfunction (ED) induced by androgen deficiency.
METHODSWe randomly divided 30 eight-week-old healthy male SD rats into six groups: 2-week control (A), 4-week control (B), 2-week castration (C), 4-week castration (D), 2-week castration + androgen replacement (E), and 4-week castration + androgen replacement (F), those in groups E and F subcutaneously injected with testosterone propionate (TP) at the physiological dose of 3 mg/kg per day after castration, while those in the other groups with isodose oil instead. At 2 and 4 weeks after operation, we determined the level of serum testosterone (T) , intracavernous pressure (ICP) , mean carotid arterial pressure (MAP) of the rats, measured the concentration of H2S in the plasma and corpus cavernosum tissue, and detected the expressions of cystathionine-P3-synthase (CBS) and cystathionine-gamma-lyase (CSE) by immunohistochemistry and Western blot.
RESULTSThe serum T level was significantly lower in group C ([0.63 +/- 0.15] nmol/L) than in A ( [ 16.55 +/- 4.17] nmol/L) and E ( [ 18.99 +/- 4.62] nmol/L) (P <0.05), as well as in group D ([0.70 +/-0.22] nmol/L) than in B ([15.44 +/-5.18] nmol/L) and F ([20.99 +/-6.41] nmol/L) (P <0. 05) , and so were ICP/MAP after 5 and 7 V electrical stimulation of the pelvic ganglia (P <0. 05) , H2 S concentration (P <0.05), and the expressions of CBS and CSE (P <0.05). The expressions of CBS and CSE proteins were also significantly decreased in group C as compared with D (P <0.05).
CONCLUSIONThe reduced expressions of CBS and CSE may inhibit the H2 S signaling pathway, which might be one of the mechanisms underlying androgen deficiency-induced ED in rats.

Objective To discuss the MRI findings of common complications following hip arthroplasty and their association with operative and pathological findings to improve the early diagnosis and etiological differential diagnosis for common complications following hip arthroplasty. Methods Forty-six patients with hip arthroplasty complication were included in this study. We observed prosthesis location, signal changes between prosthesis and bone, and periprosthesis signal changes, signal changes of articular capsule, adjacent soft tissue and bone on MR images. Diagnostic value of MRI in detecting hip arthroplasty complication was evaluated with operative and pathological findings as reference standard. Results Complications following hip arthroplasty included aseptic loosening (n=26), osteolysis (n=12), infection (n=12), heterotopic ossification (n=4), pseudoneoplasm (n=4) and periarthroplasty fracture (n=1). The MRI finding suggestive of aseptic loosening in 24 cases was a smooth intermediate signal intensity layer along the interface. Osteolysis is seen as soft tissue signal intensity material replacing normal high signal intensity fatty marrow in 12 cases. Bone marrow edema, bone destruction, fluid collection, estracapsular collections, periprosthetic muscle edema, and sinus were predictors of infection. On MRI, mature heterotopic ossification had the appearance of cancellous bone in 5 cases. Pseudoneoplasm represents fluid signal intensity with intermediate signal intensity pseudocapsule in 5 cases. Periprosthetic fracture included hypointesense fracture lines, periosteal reaction, and periprosthetic muscle edema in one patient. Conclusion MRI is useful in detecting osseous and soft-tissue abnormalities in patients with hip implants.

Pinellia ternate and Pinellia pedatisecta lectins with biological functions could be obtained through procaryon expression.Their biological similarities and differences were analyzed and further experiments were conducted to discuss the agglutinative activity difference between polymer lectin and metamer lectin.The results showed that agglutinative activity of Pinellia pedatisecta was four times more than that of Pinellia ternate.The differences of the agglutinative activity and pharmacologic action were mainly because two site mutations of Pinellia pedatisecta in the third active site compared with the amino acids sequence in Pinellia ternate.In addition,the metamer lectin expressed by prokaryotic expression system did not agglutinate rabbit red blood cells.It conduct further discussion about the difference between two lectins and the difference between polymer lectin and metamer lectin.It would be applicable for solving the problem of lacking Pinellia resources.

ObjectiveThis study was to review our experience for the management of hepatocellular carcinoma(HCC) invading the inferior vena cava(IVC). Methods Eleven patients were operated on. Tumors were first resected under portal triad clamping(PTC) and then the tumor emboli in the IVC were removed either under hepatic vascular exclusion(HVE) or under side clamping of the IVC. Results Surgery was successful in all cases, without operative death and complication caused by the removals of tumor emboli from the IVC. The mean operative time was 179 min (range 120~255 min) and the mean intraoperative blood loss 1 482 ml(range 600~3 000 ml). The mean PTC and HVE times were 27 9 min(range 12~83 min) and 16 5 min(range 7~28 min), respectively. The postoperative complications included pleural effusion in one needing thorancentesis and bile leak in one. During the follow up, 3 patients died at 30, 10 and 14 months, respectively, and the remaining 8 patients were alive at the follow up of 1 to 14 months. ConclusionsHCC with tumor thrombus in the IVC is operable and the proper procedure is hepatectomy plus thrombectomy with a favourable postoperative prognosis.

Objective: To observe the effect of mFOLFOX7 protocolon advanced gastric cancer. Methods: Forty-eight patients with advanced gastric cancer were randomly divided into two groups: conventional treatment group (24 cases, surgery-adjuvant chemotherapy)and synthesized treatment group (24 cases, mFOLFOX7 neoadjuvant chemotherapy-surgery-adjuvant). The effect and toxic reaction of mFOLFOX7 on the patients with advanced gastric cancer were observed, and the R0 resection rate, complications incidence, survival rate were compared between two groups. Results: In synthesized treatment group, total effective rate was 58.3% . Fourteen patients (58.3%)achieved R0resection in synthesized group were compared with 7 patients (29.2%)achieved R0 resection in conventional group (P0.05).Conclusion: mFOLFOX7 neoadjuvant chemotherapy protocol is low toxic reaction. It can improve R0 resection rate of advanced gastric cancer, complications correlated with surgery are not increased. But it can’t improve the survivalrate.

OBJECTIVETo investigate the effect of four natures of medicine on therapeutic effect of acupoint sticking therapy.
METHODSSixty-one cases of primary dysmenorrhea were randomly divided into a capsaicin group (n=20), a menthol group (n=20) and a control group (n=21). They were treated respectively with capsaicin and menthol, which are extracts of Lajiao (Fructus Capsici) and Bohe (Herba Menthae) with same pungent in flavor and different cold (cool) and heat in property, and application of Tongjing Jiu Tieji (plaster for dysmenorrhea) at Shenque (CV 8). Changes of clinical symptoms before and after treatment were observed.
RESULTSAfter treatment, the cumulative scores of symptoms and the scores of pain decreased significantly in the 3 groups (P < 0.01), with no significant differences among the 3 groups (P > 0.05).
CONCLUSIONIn acupoint sticking therapy, the four natures of medicine have no obvious effect on the therapeutic effect, so the four natures of medicine should not used as main standard of medicine selection.
