Objective:To analyze the effect of morphine hydrochloride sustained-release tablets given by different administration routes on patients with cancer pain.Methods: Chosen patients with cancer pain as research subjects, underwent morphine hydrochloride sustained-release tablets for treatment of pain, randomized to receive oral administration as control group and rectally administration as observation group, observed pain relief degree, onset time of analgesia and adverse reaction rates.Results:1)After treatment, the observation group patients’ overall response rate was 94.05%,no significant difference compared with the control group; 2) After treatment, the observation group patients had a mean onset time (0.68 ±0.17) h, significantly shorter than the control group,0.5h, 1h, 2h, 4h of onset percentages of analgesia were higher than control group; 3)After treatment, the observation group patients’ incidence of adverse reactions was 2.38%, significantly lower than the control group.Conclusion: The morphine hydrochloride sustained release tablets rectal administration route can significantly alleviate cancer pain, shorten onset time of analgesia, and don’t increase the incidence of adverse reactions.

Endodernal sinus tumors(EST) are generally recognized as a germ cell tumors with extraembryonicdifferentiation that resemble the endodermal sinus of the rat placenta. Like other germ cell tumors the primaryEST may either occur in the gonads or in specific extragonadal sites. CT is the most accurate study in delineatingthe extent of primary and metastatic lesions particularly in the pelvis. Recently authors experienced six cases ofthe pathologically proven extragonadal endodermal sinus tumors in children and retrospectively analyzed theradiological findings including the CT. The results were as follows: 1 Of the 6 cases of extragonadal EST, theprimary lesion presented in the sacrococcygeal region in 5 patients and liver in one patient. 2. There were 4females and 2 males. Of the sacrococcygeal lesions 3 were females and 2 were males. 3. The age of presentationranged from 9 months to 3 years of age(mean age=21 months) 4. Conventional radiographic study of thesacrococcygeal lesion showed presacral, retrorectal soft tissue mass without calcification which extended into thebuttock. CT revealed well circumscribed enhancing soft tissue mass with irregular central low density areas. 5.Primay EST of the liver revealed ill-defined inhomogeneous mixed echogenic mass( ultrasound) and ill-defined lowdensity mass(CT). Angiography showed hypervascular mass with areas of necrosis and no evidence portal veininvasion. A-V shunting was not present. 6. Reginal lymph node metastasis was present at the time of diagnosis in 2cases of sacrococcygeal EST. 7. Local recurrence of tumor was noted in 2 patients with sacrococcygeal lesion aftersurgery and chemotherapy.

Aim To produce poly (lactic-co-glycolic acid) (PLGA) microspheres, containing a staphylokinase variant (K35R, DGR) with reduced immunogenecity and antiplatclet aggregation activities,which allowed the preservation of protein stability during both particle processing and drug release.Methods DGR-loaded microspheres were fabricated using a double emulsion-solvent evaporation technique. The effects of preparative parameters, such as stirring rate, polymer concentration, and the excipients of both internal and external aqueous phase (W2 ), on DGR encapsulation efficiency and microsphere characteristics were investigated. In vitro and in vivo release of DGR were conducted and the cause for instability of DGR during release was also investigated. Results Moderate ultrasonic treatment of aqueous DGR/dichloromethane mixtures caused approximately. Eighty four per cent DGR denaturation.However, the activity recovery of DGR almost amounted to 100% when 2% polyvinyl alcohol (PVA) was added into the aqueous phase. It was found that NaCl in the external water phase significantly increased DGR encapsulation efficiency. Furthermore, NaCl in the external water phase played a role in determining size and surface morphology of microsphere. In vitro release test showed a burst release of DGR from microspheres, followed by sustained release of 50% total activity over 15 days. In vivo experiments showed that DGR released from microspheres sustained 5 days. Denaturation of DGR within microspheres might be resulted from acidic microclimate. Conclusion The stability of DGR was effectively protected during microencapsulation and a relatively high encapsulation efficiency of DGR was obtained. PLGA microspheres could be an effective carrier for DGR.

Objective To analyze the complications, treatments and prognosis of simultaneous pancreas-kidney transplantation. Methods Forty cases of simultaneous pancreas-kidney transplantation performed between Dec. 1999 and Jan. 2010 in our center were retrospectively analyzed. Results Regarding surgical complications, 4 cases had severe hematuria after operation,which needed clinical intervention, including 1 patient receiving catheterization in duodenum to stop bleeding. Two patients were treated with continuous bladder irrigation, and the remaining one received surgical haemostasis because of donor's duodenum and bladder anastomotic artery hemorrhage.Abdominal hemorrhage occurred in 4 patients, including pancreatic hemorrhage in 3 cases and duodenal muscularis hemorrhage in one case. All of them received surgical treatment for hemostasis.Abdominal infection occurred in 8 cases: one died of multiple organ failure, 2 cases were cured after drainage of abscess, 2 cases underwent surgical removal of abscess, and 3 cases were cured after antibiotic therapy. In one case of postoperative anastomotic leakage, pancreas was resected. Four cases of postoperative ileus were cured by continuous clysis with traditional Chinese medicine. Seven cases had pulmonary bacterial infections, including one cases associated with fungal infection. They were cured by the anti-infective treatment. Other complication included poor healing in 5 cases and urinary infection in 2 cases. After combined simultaneous pancreas-kidney transplantation, 10 patients received reoperation because of surgical complications (14 operations). The re-operation rate was 25 %, including 2 patients (4 operations) for hematuria, 4 patients for abdominal hemorrhage, 2 patients (3 operations) for abdominal infection, 1 patient for pancreatic venous thrombosis, 1 patient for anastomotic leakage, and 1 patient for pancreatic fistula. Conclusion Although simultaneous pancreas-kidney transplantation provides a successful and effective treatment for diabetics with endstage renal disease, surgical complication is still affecting the pancreas and kidney grafts after transplantation.

Objective To analyze the complications,treatments and prognosis of simultaneous pancreas-kidney transplantation,especially on surgical complications and treatments.Method The causes and outcomes of surgical treatment in 70 cases of simultaneous pancreas-kidney transplantation performed between Dec.1999 and June 2012 were retrospectively analyzed in our center.Result Sixteen patients (22.9％) underwent one or more reoperations.The causes for reoperation were as follows:2 cases of hematuria,4 cases of abdominal hemorrhage,4 cases of abdominal infection,4cases of pancreatic thrombosis,2 cases of renal graft's artery rupture,1 case of renal allograft rupture,1 case of intestinal fistula,and 1 case of pancreatic fistula.Eight pancreas grafts were lost in the first year.Pancreatectomy was performed on the other 5 cases:4 cases of pancreatic thrombosis,1 case of intestinal fistula,accounting for 43.8％ of the patients subject to reoperation.The recipients,kidney,pancreas survival rate in reoperation group at 1 year was 87.5％,75％,and 56.3％ respectively; and that in control group at 1 year was 98.1％,98.1 ％,and 98.1 ％ respectively.There was significant difference in kidney survival rate (P＜0.01,chi-square =6.79),and pancreas survival rate (P＜0.01,chi-square =17.47) between two groups.Conclusion Although simultaneous pancreas-kidney transplantation provides a successful and effective treatment for diabetics with end-stage renal disease,surgical treatment due to complications is still an important factor in short-term survival on the grafts.

Objective To explore the indications of simultaneous pancreas-kidney (SPK) transplantation for type 2 diabetes mellitus (DM) combined with end-stage renal disease by comparing the outcome of patients with type 1 and type 2 DM combined with end-stage renal disease after renal transplantation.Methods 109 patients accepting SPK from January 2008 to July 2016 in our center were divided into two groups according to the types of DM:T1DM (n =36),and T2DM (n =73).The basic characteristics of recipients,outcome,and pancreas and kidney functions after operation were compared between two groups.Results There was no significant difference in 5-year survival rate and surgical complications between two groups although recipients of T2DM group were older and had higher BMI than T1DM group.But rejection rate was higher in T1DM group.Conclusion SPK for T2DM recipients will not increase the surgical risk and can get good long-term outcome.

Objective To assess the distribution of recombinant fusion protein dTMP-GH in mice and to determine whether it is of tar-geted distribution characteristics. Methods A laboratory scale preparation of dTMP-GH recombinant fusion protein was obtained. Protein dT-MP-GH was labeled with radioactive 125 I,then mice were sacrificed at 5 min,15 min,30 min,1 h,2 h,4 h,8 h,12 h,24 h after tail vein injec-tion of 125 I-dTMP-GH at a dose of 100 μg/kg,and the organs and tissues ( heart,liver,spleen,kidney,bone and thyroid) were collected for radioactive counting. Results Preparation of purified ( >98%) dTMP-G was obtained. 125 I labeling rate was 71. 53%,radiochemical purity was 96. 53%,and specific activity was 0. 22 MBq/μl. 30 min after tail vein injection of 125 I labeled dTMP-GH,radioactivity accounted for 10% of the total injected in femoral,and metabolism was carried via liver and kidney over time. Conclusion Fusion protein mainly distribu-ted in bone marrow via tail vein injection in mice,which expressed that dTMP-GH has the characteristics of selective distribution in bone mar-row tissue.

Objective To discuss the ultrasonographic characteristics of schistosomal appendicitis lesions. Methods Among the patients with schistosomal hepatopathy who were discovered by Color Doppler ultrasound in Huzhou Central Hospital from January 2012 to December 2015,50 cases with clear history of schistosomiasis and treatment were chosen as a schistosom?al hepatopathy group,meanwhile,50 normal people,who came from non?endemic areas,without schistosomal hepatopathy and schistosomiasis history were chosen as a control group. The two groups were examined by ultrasound scan of the appendix ,and the data of the largest diameter of the appendix and the thickness of the appendix wall were collected,and the sonographic char?acteristics of their appendixes,such as whether the echo of the appendix wall was even or not,were observed. Results The minimum internal diameter of the appendix cavity and the thickness of the appendix wall of the schistosomal hepatopathy group were(2.090 ± 0.790)mm and(1.332 ± 0.313)mm ,respectively,the former was significantly narrower than that of the control group,while the latter was significantly thicker than that of the control group(t=2.647,-4.526,respectively,both P<0.05). The proportions of those with inhomogeneous echo,indistinctness structure,uneven thickening of the appendix wall,as well as having intestinal contents in the appendix cavity in the schistosomal hepatopathy group were higher than those in the control group(χ2=12.000,18.537,24.008,4.244,respectively,all P<0.05). Conclusions Schistosomal appendicitis lesions have obvious ultrasonographic characteristics under ultrasound. Ultrasound can play an important role in judging whether the appen?dix of schistosomiasis patients is involved and discovering the lesion of appendix early.
