OBJECTIVETo observe the effects of Jiangtang Xiaozhi Tablet (JTXZT) on decreasing the levels of blood glucose and serum lipids in KK-Ay transgenic model mice with diabetes mellitus (DM).

METHODSKK-Ay transgenic mice were fed with high fat diet to induce DM obesity model. The C57 mice of the same age were recruited as the control group. Then the modeled KK-Ay mice were divided into 5 groups, i.e., the model group, the Pioglitazone Hydrochloride Tablet treatment group (8 mg/kg, as the positive control group), and the high dose JTXZT group (10 g/kg), the middle dose JTXZT group (5 g/kg), and the low dose JTXZT group (2.5 g/kg), 11 in each group. Eight weeks was taken as one therapeutic course. All medicines were given by gastrogavage. The food intake and body weight were measured every week. The blood glucose level was determined once every 2 weeks. The levels of fasting blood glucose (FBG), serum lipids (TC and TG), insulin (INS), and leptin (Lep) were assayed 8 weeks after medication. The weight of liver and fat were weighed to calculate their indices. Then the adipose denaturalization of the liver was classified. The numbers of the pancreatic islet and adipocytes were respectively counted.

RESULTSCompared with the model group, the food intake and the body weight obviously decreased in the 3 JTXZT groups (P < 0.05, P < 0.01). From the 6th week, the FBG level obviously decreased in the high dose JTXZT group (P < 0.01). After eight successive weeks of intragastric administration, the levels of TG and INS obviously decreased in the 3 JTXZT groups (P < 0.05, P < 0.01). The Lep level somewhat decreased in the high dose JTXZT group (P < 0.05). The indices of the liver and fat obviously decreased and the number of the pancreatic islet obviously increased in the 3 JTXZT groups (P < 0.05, P < 0.01). The number of adipocytes obviously decreased in the high and middle dose JTXZT groups (P < 0.05, P < 0.01). The liver fatty degeneration was obviously improved in the high dose JTXZT group (P < 0.05).

CONCLUSIONJTXZT had obvious effects on decreasing the levels of blood glucose and serum lipids in KK-Ay transgenic model mice with DM obesity.

OBJECTIVETo evaluate the differences in oncologic outcomes between inflammatory adhesion and malignant adhesion in patients with stage IIC colorectal cancer after multivisceral resection(MVR).

METHODSA retrospective review was undertaken of 287 patients who underwent MVR for stage IIC CRC, 120 patients for stage IIB, and 140 patients for IIIA. Patients were divided into two groups: inflammatory adhesion(IA) and malignant invasion(MI).

RESULTSThere were 153 patients with colon cancer and 135 patients with rectal cancer in the stage IIC group. The overall survival was significantly lower in the MI group at 5 years(38.5% vs. 59.4%, P<0.05). Stage IIC patients with IA had similar survival rate to the patients with stage IIB CRC. Compared to the MA group, patients with stage IIIA CRC showed significant differences in 5 years overall survival rate. Univariate analysis showed that differentiation, adhesion pattern, and complication were significant prognostic factors for patients with colon cancer, while pathological characteristics, adhesion pattern, and differentiation were significant for rectal cancer.

CONCLUSIONSMI is an adverse prognostic factor for patients with stage IIC CRC. T4 should be further classified according to the adhesion pattern.

OBJECTIVETo observe effect of formula of removing both phlegm and blood stasis (TYTZ) in improving hemorheology and blood fat of mini-swine with coronary heart disease of phlegm-stasis cementation syndrome.

METHODThirty-six Chinese mini-swine were randomly divided to six groups: the normal control group, the model group, the Shujiangzhi group and TYTZ groups with doses of 2.0, 1.0 and 0.5 g x kg(-1), with six mice in each group. Except for the normal control group, all of other groups were fed with high-fat diet for 2 weeks. Interventional balloons are adopted to injure their left anterior descending artery endothelium. After the operation, they were fed with high-fat diet for 8 weeks to prepare the coronary heart disease model of phlegm-stasis cementation syndrome. In the 8th week after the operation and administration, the changes in hemorheological parameters, serum lipid level, myocardial ischemia level and range were observed.

RESULTCompared with the normal control group, the model group showed significant increase in serum TC, TG, LDL-C and VLDL-C levels (P < 0.01), whole blood viscosity under the shear rate of 5 s (-1) and 60 s (-1) (P < 0.01), and myocardial ischemia degree and range (P < 0.01). Compared with the model group, TYTZ groups revealed significant decrease in myocardial ischemia degree and range (P < 0.01), serum TC, TG, LDL-C and VLDL-C levels (P < 0.05 or P < 0.01) and whole blood viscosity under the shear rate of 5 s(-1) and 60 s(-1) (P < 0.05).

CONCLUSIONTYTZ could improve the abnormal hemorheology in Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome, and regulate serum lipid, with a certain efficacy for coronary heart disease of phlegm-stasis cementation syndrome.

OBJECTIVETo explore the effect of Jiangtang Xiaozhi capsule (JXC) on morphological changes of islets and liver at rat model of type 2 diabetic mellitus and provide the experimental basis for the clinical therapy of type 2 diabetic mellitus.

METHODWister rats were fed on a diet enriched in fat and glucose to induce insulin resistan, the rats were injected intrapertoneally with a low-dose streptozotocin (STZ) twice (25 mg x kg(-1)) to induce hyperglycemia, so the successful rat model of type 2 diabetes were established. The experimental rats were divided into model group, high dose JXC group, middle dose JXC group, low dose JXC group, Erjiashuanggua group, Jinqijiangtang group and normal control group. After all the treatment groups received their own medicine for two months, all the rats were sacrificed and morphological examination on their islets and livers were performed.

RESULTFatty liver in various degrees was seen in the model group and all the treatment groups, but the liver steatosis in middle and low dose JXC groups was significantly milder than that in model group (P < 0.05). Islets in the high dose JXC group were significantly more than that in the model group (P < 0.05).

CONCLUSIONJXC can improve significantly the pathological change in islets and liver steatosis at rat model of type 2 diabetic mellitus.

BACKGROUNDOne of the major characteristics of the human immunodeficiency virus type 1 (HIV-1) is its unusually high degree of genetic variability, which involves in genetic diagnosis, subtyping, vaccine design, and epidemiology. HIV-1 CRF01_AE is a main prevalent HIV-1 recombinant strain in China. In this study, three full-length CRF01_AE genomes from Fujian Province, China were cloned, sequenced, and analyzed; and the further genetic diversity defining and epidemiologic analysis were carried out.

METHODSProviral DNA was extracted from non-cultured peripheral blood mononuclear cells, the near full-length HIV-1 genome was amplified and the PCR products were cloned into pCR-XL-TOPO vector and sequenced. 5'-long terminal repeat (LTR) and 3'-LTRs were amplified by additional independent PCR and cloned into pMD18T vector. Gene-based phylogenic tree was constructed and genetic distances were calculated by MEGA 3.1. Simplot was used for Bootscan analysis.

RESULTSThe phylogeny and genetic distance analysis of the three near full-length sequences confirmed that these three samples clustered with CRF01_AE isolates, more close to Thailand CRF01_AE strain CM240, and were distantly related to African CRF01_AE strain 90CF402. Analysis of their genomic organization revealed the presence of nine potential open reading frames. There were no major deletions, rearrangements, or insertions in the three sequences, but an in-frame stop codon was found in tat gene of Fj051. LTRs of the three sequences contained a few nucleotides mutation. We did not find new mosaic recombinant in the three sequences. The V3 motif was GPGQ in all the three sequences, and there were only few amino acids differences in all three V3 loop sequences.

CONCLUSIONThis report reveals the background of the three full-length CRF01_AE genomes, the most dominantly circulating HIV-1 strain in Fujian Province, China. The work is essential for the design and development of an effective AIDS vaccine for the region.

OBJECTIVETo investigate the effect of transcatheter hepatic arterial chemoembolization (TACE) therapy on the survival and prognosis of recurrent hepatocellular carcinoma (HCC) after surgical resection.

METHODSThe data of 130 surgically resected but recurrent HCC patients treated by TACE were reviewed retrospectively. The survival and influencing factors on the prognosis were analyzed.

RESULTSThe overall 1-, 3-, 5-year survival rates of these 130 patients were 83.0%, 45.5% and 17.6% respectively (median survival time 2.4 years). Ninty-four of the series were treated with TACE alone, which gave the 1-, 3- year survival rates of 76.4% and 37.1%, respectively (median survival time 2.1 years). Thirty-six out of 130 patients treated with TACE plus percutaneous ethanol injection (PEI), the 1-, 3-year survival rates were 100.0% and 66.5% respectively with a median survival time (MST) of 3.5 years. The survival of TACE plus PEI group was significantly better, and the mortality risk was significantly lower than that of TACE alone group (P < 0.05). The mortality risk of those with > 5 cm diameter recurrent tumor or with distant metastasis was significantly higher than those with < or = 5 cm diameter tumor or without metastasis (P < 0.05).

CONCLUSIONTACE combined with PEI may improve the survival of recurrent HCC patients.

OBJECTIVETo explore the methods of systemic treatment of defects of skin and soft tissue on the knees after severe trauma or burn.

METHODSTwenty patients with defects of skin and soft tissue on the knees after severe trauma or burn hospitalized in our center from January 2009 to December 2011. The injury areas on the knees ranged from 5 cm×4 cm to 30 cm×20 cm. The wounds were treated with radical debridement, vacuum sealing drainage, and douche through dripping to control infection in early stage. Then they were covered with transplantation of skin grafts plus flap or only with flap. Totally 8 local flaps (including 6 local rotation or transposition flaps and 2 saphenous artery flaps) and 12 free flaps (including 8 anterolateral thigh flaps and 4 latissimus dorsi musculocutaneous flaps) were used. The flap size ranged from 6 cm×5 cm to 32 cm×22 cm. The rehabilitation training of the knee joints was carried out in the early stage after wound healing.

RESULTSAll free skin grafts and flaps used in 15 patients survived. Thirteen of them were primarily healed, while some small parts of skin grafts of the other two patients were in poor condition because of infection, and they healed after another session of skin transplantation. Infection occurred under the free flap in one of the 5 patients transplanted with flaps only, which was healed after continuous douche through dripping and another surgical debridement following wet dressing. The knee joints were in good function during the follow-up period of 1 - 3 years.

CONCLUSIONSThe systemic therapy of radical debridement, vacuum sealing drainage technique, douche through dripping, transplantation of large autologous grafts and flaps, and the early rehabilitation training are effective and reliable in repairing defects of skin and soft tissue at the knee region after severe injuries.

OBJECTIVETo evaluate the efficacy and analyze the prognostic factors of sorafenib treatment in patient with unresectable primary hepatocellular carcinoma (HCC).

METHODSDuring the period from December 2005 to March 2009, 50 patients with unresectable primary HCC of Child-Pugh status A were treated with sorafenib (400 mg, Bid). The tumor response was evaluated with CT or MRI imaging every 6 - 8 weeks according to the RECIST criteria. The overall survival (OS) and time to progression (TTP) were defined as the time from administration of sorafenib to the death or the last follow up and were evaluated by Kaplan-Meier method.

RESULTSThere was no PR or CR, but 28 patients (56.0%) achieved stable disease. The median follow up time was 15 months with a median OS of 14 months and median TTP of 4 months. The common adverse events were dermal reaction (68.0%, 34/50), diarrhea (52.0%, 26/50), hypertension (4.0%, 2/50), hair loss (14.0%, 7/50), myelosuppression (16.0%, 8/50), and liver dysfunction (20.0%, 10/50). However, most of the drug-related adverse events were grade I-II and reversible. The patients with lower tumor burden and without distant metastasis had better prognosis.

CONCLUSIONSoafenib is effective for unresectable primary HCC with tolerable toxicity. Tumor stage is a predominant prognostic factor.

OBJECTIVETo study surgical strategies for ankle and foot deformities secondary to spina bifida and treatment methods for different types of deformities.

METHODSFrom January 1990 and July 2009, 107 patients with ankle and foot deformities secondary to spina bifida were retrospectively analyzed. There were 44 males and 63 females, with an average age of 17.7 years (rangd from 1.3 to 52 years). Among the patients, 58 patients had double ankle deformities, 49 patients had unilateral deformities (22 cases on the left side, 27 cases on the right). Ninety-nine patients with equinus deformities were treated by achilles tendon lengthening and tendon transfering; 25 patients with talipes were treated by release of anterior tendon of ankle and tendon transfer; 17 patients with valgus and varus deformities were treated by tendon transfer and calcaneal osteotomy; 15 patients with flail deformities were managed treated by bone fusion between calcaneus and talus and shortening of achilles tendon; 9 patients with claw toe deformities were treated by bone fusion of interphalangeal joint or Ilizarovs distraction. AOFAS (American Orthopaedic Foot & Ankle Society) comprehensive scoring system was used to evaluate subjective pain and objective functional.

RESULTSSeventy-nine (127 feet) of 107 patients were followed up, and the duration ranged from 48 to 180 months (averaged, 64 months). According to AOFAS scoring system, the results were rated as excellent in 89 feet, good in 26 feet, moderate in 9 feet and poor in 3 feet.

CONCLUSIONTreatment strategies for ankle-foot deformities mainly included four principles, deformity correction, muscular balance, joint stability and reservation of foot elasticity. Different combined procedure was applied for different foot deformities and received good therapeutic effects.
