Objective To explore the prognostic value of the content of lentil lectin-reactive alphafetoprotein-L3(AFP-L3)in early-stage hepatocellular carcinoma(HCC).Methods According to the content of alpha.fetoprotein(AFP)and AFP-L3 before the treatment,97 patients with early-stage HCC were divided into group A(AFP＞20 μg/L & AFP-L3＜15%,n=29),group B(15%≤AFP-13≤50% & 20 μg/L≤AFP≤200 μg/L,n=16),group C(AFP-13＞50%& AFP＞200 μg/L,n=13),group D(AFP-L3＞50% & 20 μg/L≤AFP≤200 μg/L,n=24)and group E(15%≤AFP-L3≤50%& AFP＞200 μg/L,n=15).The degree of tumor differentiation,the 1-,2-,3-year survival rates and tumor-free survival rates of the patients were analyzed.Results The degree of tumor differentiation.3-year survival rate and tumor-free survival rate of patients in group A were significantly higher than those in the other 4 groups(χ2=21.051,10.043,4.450,6.977,25.566,P＜0.05).The degree of tumor differentiation,1-,2-,3-year survival rates and tumor-free survival rates of the patients in group C and D were significantly lower than those in other 3 groups(χ2=7.938,3.488,9.085.P＜0.05).Conclusions The increase of AFP-L3 content is closely related to poorly differentiated HCC and bad prognosis.especially when the AFP Ievel is low.The detection of AFP-L3 content before and after operation is beneficial to the evaluation of the prognosis of HCC patients.

OBJECTIVETo study the syndrome of inappropriate ADH secretion (SIADH) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the possible etiology.

METHODSThe clinical manifestation, laboratory examination, treatment and outcome of a patient with refractory anemia with excess blasts after allo-HSCT were presented.

RESULTSHyperacute graft-versus-host disease (GVHD) was developed in the patient after allo-HSCT followed by severe hyponatraemia (lowest serum sodium 103.7 mmol/L), natriuresis, hypo-osmolality of plasma, hyper-osmolality of urine, coma and twitch at day 17 after allo-HSCT. SIADH was diagnosed. The clinical condition was improved after restriction of water and administration of hypertonic saline, but SIADH was not controlled completely. Afterwards, graft failure was developed. Hyperacute GVHD and graft rejection occurred again after the second transplant. The patient died of secondary infection.

CONCLUSIONSIADH after allo-HSCT is a rare fatal acute complication of central nervous system. Numerous transplant-related causes are probably associated with the development of SIADH. Early accurate diagnosis and treatment promptly is of great importance.

Objective To investigate the effect of electroacupuncture on the expressions of in-terleukin(IL)-33 and ST2 in spinal cord and dorsal root ganglion in rats with neuropathic pain. Methods Forty adult female SD rats were randomly divided into sham operation group (group Sham),model group (group MC),ipsilateral electroacupuncture group (group SE)and contralateral electroacupuncture group (group VE).Each group had 10.The sciatic nerve injury models were es-tablished.The rats in group SE and group VE were respectively accepted electrical acupuncture treat-ment in Yanglingquan and Zusanli in the right and left limbs.Respectively,before treatment (T0 ), treated for 7 d (T1 ),3 d (T2 )and 7 d (T3 )after treatment,the MWT and TWL of rats in the four groups were measured.At T3 ,the expressions of IL-33 in spinal cord and dorsal root ganglion in rats were detected by using quantitative PCR.Results Compared with T0 ,MWT and TWL in group MC, group SE and group VE at T1-T3 were decreased significantly (P < 0.05).Compared with sham group,MWT in group SE and group VE,TWL in group MC,group SE and group VE at T1-T3 were decreased significantly (P <0.05).Compared with group MC,MWT and TWL in group SE and group VE at T2 ,T3 were increased significantly (P <0.05).Compared with sham group,the relative expression levels of IL-33 mRNA and ST2 mRNA in spinal cord and dorsal root ganglion in the group MC,group SE and group VE were elevated,the differences were statistically significant (P <0.05). Compared with group MC,the relative expression levels of IL-33 mRNA and ST2 mRNA in spinal cord and dorsal root ganglion group SE and group VE were decreased,the differences were statistical-ly significant (P <0.05).Conclusion The electroacupuncture treatment could significantly reduce the pain symptoms of neuropathic pain in rats,possibly via inhibiting the expressions of IL-33 and ST2 in spinal cord and dorsal root ganglion and blocking the IL-33/ST2 mediated inflammatory to play role.

Objective To investigate the ideal dosage of dexmedetomidine( DEX) with 1?0 μg/kg fentanyl for monitored anesthesia care ( MAC) during endoscopic variceal ligation ( EVL) . Methods A total of 60 patients scheduled for elective EVL were randomly divided into 3 groups ( n=20) . After fentanyl was infused intravenously at the dosage of 1?0 μg/kg, the loading dosage of DEX at 1?0 μg/kg ( group D1 ) , 1?5 μg/kg ( group D2 ) , or 2?0μg/kg ( group D3 ) was continuously infused in 10 min, respectively. When the modified OAA/S score reaching≥3 point, EVL was carried out. The change in modified OAA/S score, the operation duration time, recovery time, satisfaction rates of patient and doctor, and complications were recorded. Results There were no significant differences in regarding of general status, operation duration time and satisfaction score of patients between the 3 groups ( P>0?05 ) . Before endoscope insertion, the OAA/S score in group D3(4?4±0?2)was higher than that in D1(3?4±0?5)or D2 groups(3?8±0?3)(P<0?05), and there was no significant difference between the scores of D1 and D2(P>0?05).At the time?point of 5 mins after endoscope insertion, the OAA/S score in group D3(4?5±0?3)was significantly higher than that in D1(3?5±0?6)or D2 groups(3?7±0?4)(P<0?05),there were no significant differences between D1 and D2( P>0?05) . At the end of the procedure,there was no significant difference in OAA/S score between the 3 groups(P>0?05).Compared with group D1(3?1±0?9)min and D2(3?8±0?8)min, the recovery time in group D3(6?6±1?2)min was significantly longer (P<0?05), while there was no significant difference between D1 and D2(P>0?05). The satisfaction score of endoscopist in group D1(8?0±0?8) was significantly lower than that in group D2(9?4±0?6)or D3(9?5±0?5)(P<0?05), there was no significant difference between groups D2 and D3 ( P>0?05 ) . No tachycardia, hypertension or hypoxemia occurred during the procedure. There was no significant difference in rate of hypotension among the three groups ( P>0?05) . The incidences of nausea(30%) and body movement(15%) in group D1 were significantly higher than those in group D2 and D3(P<0?05).There were no differences between D2 and D3(P>0?05). The incidence of bradycardia in group D3(40%) was significantly higher than those in group D1(0) and D2(10%)(P<0?05).There were no differences between those in D1 and D2(P>0?05). Conclusion Combined with 1?0 μg/kg fentanyl, 1?5 μg/kg DEX is more efficient and safer for EVL in the status of MAC.

Objective To explore the short and long term result and the impact on cell immunity of splenic radiofrequence ablation in patients with hypersplenism.Methods In this study 43 patients were divided into the RFA treatment group(22 cases)and open splenectomy control group(21 cases).Blood samples were collected for blood routine,lymphocyte transformation efficiency,NK cell activity and T lymphocyte subpopulations at 1 week,1 month,6 month,1 year,2 years and 3 years before and after operation respectively and the results were compared between the two groups.Results The hypersplenism of the patients in both groups were relieved.There were no significant difierences in cell indices between the postoperative and preoperative values in the two groups.In the control group,compared with the preoperative values in the trial group,the postoperative NK cell activity and lymphocyte transformation efficiency were significantly reduced(P＜0.05).Even though,with time,the NK cell activity and lymphocyte transformation efficiency were on an increasing tendency after operation but still significantly lower than that before operation.In the control group,compared with the preoperative values,CD4+T cell count and CD4+/CD8+ratio decreased significantly(P＜0.05).Moreover.with time.these indices were on an increasing tendency.CIM+T cell count and CD4+/CD8+ ratio restored to the preoperative values within 30 months(P=0.078)and 36 months(P=0.103)respectively.Conclusion RFA treatment for hypersplenism preserves a part of the spleen and thus preserves patient's cell immunity.This treatment exhibits microinvasiveness and few complications and being easy to operate.Hence,RFA treatment for hypersplenism merits wide clinical application.
