Objective To investigate the effect of recipient's pre-transplant triglyceride (TG) abnormalities on early graft function (EGF) after kidney transplantation.Methods According to the inclusion and exclusion criteria,154 identified living-kidney transplant recipients in the 309 Hospital of Chinese PLA from Jan.2011 to Dec.2014 were enrolled in present study,including 124 males and 30 females,and aged of 31.9 ± 8.4 years.The cohort was divided into two groups:TG normal group (0.40＜TG≤1.70mmol/L,n=107) and TG abnormalities group (TG＞l.70mmol/L or require lipid lowering therapy,n=47).The incidences of poor early graft renal function (PEGF),slow graft function (SGF) and delayed graft function (DGF) were compared between the two groups,and then the serum creatinine (Scr) levels were compared among the patients showing immediate graft function (IGF) at 3rd,7th and 30th day after transplantation.The ROC curve was drawn up taking TG as diagnosis index to explore the optimal cut-offvalue for predicting PEGF,SGF and DGF after transplantation.Results Compared with the TG normal group,the TG abnormalities group showed significantly higher incidence of PEGF and DGF (P＜0.05).Among the IGF patients,the TG abnormalities group showed higher Scr level at the 7th and 30th day after transplantation (P＜0.05).The area under ROC curve (AUC) reflected TG levels for PEGF,SGF and DGF were 0.774,0.704 and 0.818,respectively (P＜0.05).The optimal cut-offvalues were all 1.37mmol/L.Conclusions Recipients with abnormal pre-transplant TG level may have worse EGF after renal transplantation.The risk of developing PEGF,S GF and D GF tends to emerge when pre-transplant TG level is higher than 1.37mmol/L.

Objective: To investigate the serotype and drug resistance of 815 Salmonella isolates from Hunan Province, so as to provide insights into management of Salmonella infections. Methods: Salmonella isolates were collected from stool samples of foodborne diarrheal patients and food samples in Hunan Province from 2020 to 2021, and serotyped. Antimicrobial susceptibility test was performed using the broth microdilution method. Results: A total of 10 groups and 39 serotypes were characterized in 815 Salmonella isolates. Among the 646 Salmonella isolates of human sources, 388 isolates were identified as serogroup B (60.06%), with S. typhimurium and its variants aspredominant serotypes (364 isolates, 56.35%), and among 169 foodborne isolates, 61 isolates were characterized as serogroup B (36.09%) with S. london as the predominant serotype (26 isolates, 15.38%). There were 597 antimicrobial resistant Salmonella isolates of human sources, with a drug resistance rate of 92.41%, and the percentage of ampicillin resistance was 81.58%. There were 140 foodborne antimicrobial resistant isolates, with a drug resistance rate of 82.84%, and the proportion of tetracycline resistance was 72.78%. However, Salmonella isolates from both humans and foods were sensitive to imipenem. In addition, there were 577 multidrug resistant Salmonella isolates, including 490 multidrug resistant isolates of human sources and 87 foodborne multidrug resistant isolates. Conclusions S. typhimurium and its variants and S. london were predominant serotypes of Salmonella isolates from 815 foodborne diarrheal patients and food samples in Hunan Province from 2020 to 2021, and a high rate of multidrug resistance was detected.

OBJECTIVEA retrospective review of seventeen patients who were operated through the maxillary swing approach was carried out to assess the efficacy of this approach in the management of tumors of the central and lateral cranial base.

METHODSFrom May 2000 to January 2005, 17 patients with primary or recurrent neoplasms involving the central cranial or lateral base underwent surgical resection via maxillary swing approach. Ten patients were male, and other seven patients were female, and age range was 7 to 58 years, with a mean age of 42. 6 years. Eight patients had tumors originally involving lateral cranial base, and nine patients had tumors originated from central cranial base. The pathology spectrum was very wide. Among them, five suffered from chordoma, two had rhabdomyosarcoma, two had squamous cell carcinoma, one had malignant fibrous histiocytoma, one had malignant melanoma, one had esthesioneuroblastoma, one had invaded hypophysoma, two had schwannoma, one had pleomorphic adenoma, and one had angiofibroma. Three patients had received previous surgery, two patients had previous radiation therapy and nine patients received postoperative radiotherapy.

RESULTSSixteen of all seventeen patients had oncologically complete resection, one had near-total resection. This group patients was followed up from 10 to 60 months, with a median follow-up time of 28 months. Two patients died 14 and 26 months after surgery respectively, as a result of local recurrence and metastasis. One patient defaulted follow-up at 12 months after operation, and the other 14 patients were alive at the time of analysis. Of the 12 malignant tumors, the 1-and 2-year survival rate were 91.67% and 72.92%, respectively. The facial wounds of all patients healed primarily, and there were no necrosis of the maxilla, damage of the temporal branch of the facial nerve, lower-lid ectropion, and facial deformity. Epiphora and facial hypoesthesia were detected in all patients. Four patients (23.5%) developed palatal fistula, ten patients developed serous otitis media (58.8%), and four patients developed a certain degree of trismus (23.5%). Cerebrospinal fluid leak occurred in two patients. They subsequently healed with conservative management.

CONCLUSIONSThe maxillary swing approach is a proven method for access to the central and lateral skull base with good exposure and acceptable morbidity. Complications and sequelae associated with this approach include facial scarring, transaction of the infraorbital nerve, impaired lacrimal drainage, eustachian tube dysfunction and serous otitis, palatal fistula, trismus etc. Some procedures should be performed for reducing the incidence and severity of complications in the maxillary swing approach.

OBJECTIVETo study the effect of Shugan Jiangu Recipe (SJR) on bone mineral density (BMD) and serum bone metabolic biochemical markers in postmenopausal breast cancer patients with osteopenia.

METHODSTotally 38 patients of postmenopausal women with breast cancer, who received aromatase inhibitors (AIs), were assigned to the treatment group (21 cases) and the control group (17 cases) by using random digit table. All patients took Caltrate D Tablet (containing Ca 600 mg and Vit D3 125 IU), one tablet daily. Patients in the treatment group took SJR, 6 g each time, twice daily for 6 successive months. The bone mineral density (BMD) level was detected before treatment and at months 6 after treatment. Levels of bone alkaline phosphatase (BALP), bone gla protein (BGP), tartrate-resistant acid phosphatase (TRAP), and C-terminal telopeptide of type II collagen (CTX-II) were detected by enzyme linked immunosorbent assay (ELISA). The drug safety was also assessed.

RESULTSCompared with before treatment, BMD of L2-4 and femur neck obviously increased in the treatment group at month 6 after treatment (P < 0.01), serum BALP and TRAP decreased (P < 0.05). Compared with before treatment, BMD of L2-4 and femur neck obviously decreased in the control group at month 6 after treatment (P < 0.05), serum BALP and TRAP increased (P < 0.01). Compared with the control group, lumbar and femur neck BMD obviously increased, serum levels of BGP and BALP obviously decreased, and serum levels of CTX-II and TRAP obviously increased in the treatment group at month 6 after treatment (P < 0.01). No serious adverse event occurred during the treatment period. Bone fracture occurred in one case of the control group (5.8%).

CONCLUSIONSJR could attenuate bone loss of postmenopausal women with breast cancer who received AIs, increase BMD and improve abnormal bone metabolism.

OBJECTIVETo explore a new method for identification Astragali Radix from its adulterants by using ITS sequence.

METHODThirteen samples of the different Astragali Radix materials and 6 samples of the adulterants of the roots of Hedysarum polybotrys, Medicago sativa and Althaea rosea were collected. ITS sequence was amplified by PCR and sequenced unidirectionally. The interspecific K-2-P distances of Astragali Radix and its adulterants were calculated, and NJ tree and UPGMA tree were constructed by MEGA 4.

RESULTITS sequences were obtained from 19 samples respectively, there were Astragali Radix 646-650 bp, H. polybotrys 664 bp, Medicago sativa 659 bp, Althaea rosea 728 bp, which were registered in the GenBank. Phylogeny trees reconstruction using NJ and UPGMA analysis based on ITS nucleotide sequences can effectively distinguish Astragali Radix from adulterants.

CONCLUSIONITS sequence can be used to identify Astragali Radix from its adulterants successfully and is an efficient molecular marker for authentication of Astragali Radix and its adulterants.

OBJECTIVETo compare the clinical characteristics of gastric cancer between young and elderly patients,and bring forward corresponding countermeasures.

METHODSClinical characteristics, treatment and prognosis between 79 young (or= 65 years old) patients were compared.

RESULTSThe constituent ratio of gender between young and elderly group was not significantly different (P=0.226). There was no particularity of early symptom in young patients, but they had shorter course of disease (165 d vs 400 d, P=0.029) and more frequent inferior part of cancer (49.4% vs 41.7%, P=0.038) as compared to elderly patients. There was significant difference between two groups in pathological stage ratio (P=0.027). The median total survival time of young and elderly patients was 1006 d and 530 d respectively, which was not significantly different (P=0.108). Furthermore, median survival time of young and elderly patients after radical resection were 1197 d and 919 d respectively, and the difference was not significant as well (P=0.242).

CONCLUSIONSCharacteristics of young patients with gastric cancer are lower incidence, larvaceous symptoms, more malignancy and quick development, which still remain general features of gastric cancer. By correct therapy, the efficacy of above young patients is similar to elderly patients. The key to improve prognosis is to further fortify cognition for gastric cancer and elevate early diagnostic rate.

OBJECTIVETo clarify the gene type of Orientia tsutsugamushi (Ot) from Shandong province.

METHODSNested-polymerase chain reaction (nPCR) was used to identify the gene type of 23 isolated Ot strains, 2 pools of homogenized leptotrombidium (L.) scutellare, 10 blood specimens of scrub typhus patients, and at the same time to compare with the international reference strains Gilliam, Karp, Kato. Sequencing analysis of the Sta56 gene was also used to further identify the precise gene types.

RESULTSOf the 35 samples, 33 had the same products in the amplification of template Ot-DNA. They all belonged to Kawasaki strains endemic in Japan while 2 (FXS4 and LHGM2 strain) belonged to Karp strains. The Sta56 gene sequence homologies to Japan Kawasaki strain of the 2 representative strains (B-16 and FXS2 strain) of the 33 samples were 94.22%, 95.21% respectively, but they were less than 75.87% to other prototype strains; The homologies to Karp strain of FXS4 and LHGM2 strain were 83.03%, 96.45% respectively. B-16 and FXS2 strain were designated as of types strain Japan Kawasaki, FXS4 and LHGM2 as Karp strain.

CONCLUSIONThe results indicated that the dominant Ot strains in Shandong Province were similar to Kawasaki strains, but Karp strains also existed.

OBJECTIVEThis research intends to amplify the entire coding region sequences of SLC25A13 mRNA which encodes citrin, and to investigate sequence features of the transcripts for this gene in cultured human amniocytes. This study will provide laboratory evidence for prenatal diagnosis of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) at mRNA level.

METHODSOne amniocyte sample was collected from a pregnant woman who underwent prenatal diagnosis of citrin deficiency and whose fetus has proven a carrier of 851del4 mutation by genomic DNA analysis. Another amniocyte sample, as a control, was from a fetus without family history of citrin deficiency. Total RNA was extracted from cultured amniocytes, cDNA was synthesized, and then nested-PCR was performed to amplify the entire coding region sequences of SLC25A13. The PCR products were cloned and analyzed by sequencing.

RESULTSThe entire coding region of SLC25A13 gene was successful amplified from two cultured human amniocytes. The splice variant of SLC25A13, SLCA (normal mRNA), was identified in the two samples. SLCB (CAG insertion between exon 9-10) was identified in the control. SLCC (exon 5-11 skipping), but not transcriptional product from the allele with 851del4 mutation, was identified in the 851del4 mutation carrier.

CONCLUSIONSThis study demonstrated that the entire coding region of SLC25A13 cDNA can be successfully amplified from two cultured human amniocytes, and revealed exon 5-11 skipping as a novel SLC25A13 transcript. Normal mRNA predominated in the transcripts in normal control and 851del4 mutation carrier, suggesting that the two fetuses were not at risk for NICCD. These SLC25A13 transcription features provided laboratory evidence for prenatal diagnosis of NICCD.

OBJECTIVETo compared the effect between early anatomical open reduction, internal fixation (ORIF) and closed reduction, internal fixation (CRIF) for treatment of children displaced femoral neck fracture.

METHODSFrom March 2006 to May 2010,34 children with displaced femoral neck fractures were reviewed retrospectively. These patients were divided into two groups. Among them, 19 cases were treated by open reduction and internal fixation (ORIF) as group A, included 11 males and 8 females with an average age of (8.1 +/- 1.3), the other 15 cases were treated by closed reduction and internal fixation (CRIF) as group B, included 9 males and 6 females with an average age of (7.9 +/- 1.5). Complications were observed and the short term effectiveness was evaluated by Ratliff standard.

RESULTSAll children were followed-up from 1 to 3 years (means 1.2 years). All fractures were healed. There was statistical different in the curative effects between the two groups (Z=2.389, P= 0.017). The incidence of complications in two groups had statistical different (P=0.046).

CONCLUSIONThe early ORIF could get better reduction with fewer complications than CRIF in fractures of the displaced femoral neck in children in Delbet type-II and type-III, therefore, ORIF should be considered.

OBJECTIVETo identify plasma biomarkers with specific relation to the various liver fibrosis stages that can be used to assess hepatitis B virus (HBV)-infected patients for non-invasive liver fibrosis and to evaluate the prognosis of the liver fibrosis.

METHODSPlasma samples were collected from 80 HBV-positive patients at the Hepatitis Department of Shanghai Public Health Clinical Center between September 2008 and January 2011. The samples were grouped according to the patient's stage of hepatic fibrosis determined by liver biopsy: S0-1 (n = 40), S2-3 (n = 20), and S4 (n = 20). Each plasma sample was processed to remove the two most abundant proteins, albumin and immunoglobulin G (IgG), and then resolved by two-dimensional (2D) electrophoresis. ImageMaster 2D analysis software was used to identify differentially expressed proteins related to the liver fibrosis stages. After trypsin digestion, the differential proteins were identified by online reversed-phase nano-flow liquid chromatography coupled with electrospray ionization ion trap mass spectrometry (MS).

RESULTSThe patients in the three groups were not significantly different in age (range: 30-50 years; P = 0.053) or sex (x² = 0.155, P = 0.926). Low-abundance proteins were efficiently enriched by the albumin/IgG depletion method. Fourteen differentially expressed proteins were detected among the S0-1, S2-3 and S4 groups, all of which were identified by tandem MS and included fibrinogen gamma chain, haptoglobin, complement C3, Ig kappa chain C region, and apolipoprotein A-I.

CONCLUSIONPlasma proteomic analysis of chronic hepatitis B patients identified a panel of differentially expressed proteins related to different stages of liver fibrosis. These proteins may represent diagnostic and prognostic biomarkers of HBV-related hepatic fibrosis.
