OBJECTIVETo study the serum proteomics in hypertension patients with Gan-Dan damp-heat syndrome (GDDH) for tentatively find special proteins associated with the syndrome.

METHODSStudy was performed in 60 hypertensive patients and 39 healthy persons as control. In the patients enrolled, 40 were differentiated as GDDH syndrome and the other 20 as non-GDDH syndrome. Their serum proteins were captured by weak cation nano-magnetic beads, and proteomic fingerprint was made by matrix assistant laser demodulation ionizing time-of-flight mass spectrometry (MALDI-TOF-MS) through mapping with protein chip reader type PBS II-C. After all the proteomic fingerprints being analyzed by Biomarker Wizard 3.1, the special expressed proteins for GDDH syndrome were identified by Biomarker Patterns Software 5.0 to create the syndrome decision model.

RESULTSTotally, 182 difference protein peaks between patients of GDDH and healthy persons (P<0.05); and 132 difference protein peaks between patients of GDDH and non-GDDH were detected (P<0.05). A decision model consisted 5 screened out protein peaks with mass-to-charge ratio of 2761.555, 6624.362, 2487.192, 2461.610 and 2744.318 was created, which could well differentiate the GDDH syndrome, with the sensitivity of 96.55%, specificity of 90%, false positive rate of 10% and false negative rate of 3.45%. Further blind test for prospective check showed its sensitivity being 81.82%, specificity 89.66%, false positive rate 10.34% and false negative rate 18.18%.

CONCLUSIONThe differently expressed protein is the material foundation of GDDH syndrome; molecular biological decision model established on the basis of this foundation can offer a tool for making Chinese medicine syndrome differentiation more objectively and accurately.

OBJECTIVETo evaluate color Doppler ultrasonography (CDU) appearances of renal vein thrombosis (RVT) and its diagnostic value.

METHODSTen patients with RVT were analyzed retrospectively. Renal structure, distributions of intrarenal flow signals, echogenicity, and flow fullness in main renal veins were observed with CDU. Resistance index (RI) was recorded from the waveforms of segmental or interlobar renal artery.

RESULTSTen kidneys in nine patients were confirmed to have thrombus within the main renal veins, and one patient was confirmed to have thrombus within the small intrarenal veins. The appearances of the main renal vein thrombosis included full of solid echogenicity or strip echogenicity and complete or partial filling defect within the main renal veins, and absent or a few intrarenal venous flow signals in 70% of kidneys involved. The appearances of intrarenal vein thrombosis included obscure renal structure and no venous flow signal within the involved part of the kidneys. Reverse diastolic flow in the intrarenal artery had only a sensitivity of 36% (4/11); in other 7 kidneys without intrarenal arterial reverse diastolic flow, increased RI (mean, 0.84; range, 0.74-0.96) was found.

CONCLUSIONCDU is helpful for rapid clinical diagnosis and follow-up of RVT, and therefore can be the first imaging modality of choice for RVT.

OBJECTIVETo investigate the epithelial growth factor (EGF) expression of EGF gene-transfected keratinocytes and its effect on cell proliferation after grafting.

METHODSNewborn Balb/c mouse keratinocytes and gene transfected keratinocytes were seeded on the surface of acellular dermal matrix and cocultured in different ratios as follows: 1:1, 1:3, or 1:5 1 week after culture. The composite skin was grafted onto the full-thickness wound in Balb/c mouse. Specimen was harvested at interval after grafting and underwent the immunohistochemistry staining for EGF and proliferating cell nuclear antigen (PCNA).

RESULTSImmunohistochemical staining showed EGF was expressed in the newly generated epidermis 1-2 week after grafting of the composite skin comprising Balb/c mouse keratinocytes and gene-transfected keratinocytes (at the ratio of 1:5). One week after surgery, Anti-PCNA positive basal cells were more than that in composite skin containing Balb/c mouse keratinocytes alone (P<0.01).

CONCLUSIONThe gene-transfected keratinocytes expresses EGF and promotes the proliferation of keratinocytes in the early stage after transplantation.

OBJECTIVETo clone novel gene from suppression subtraction library established for screening down-regulated genes in gastric carcinoma, and the effects of novel gene on gastric tumorigenicity were analyzed.

METHODSSequencing results of 860 positive colonies chosen randomly were compared by Blast program in GenBank. Novel gene fragment was amplified by rapid amplification of cDNA ends (RACE). The mRNA expression of novel gene was detected by Northern blot and semi-quantitative PCR in 25 cases of gastric carcinoma tissue and counterpart normal gastric mucosa. The structure and chromosomal location of novel gene were investigated by Bio-message technique.

RESULTSA 233 bp novel gene fragment was screened out from 860 clones and a 802 bp novel gene was obtained by RACE. The novel gene was named as GDDM, registered in the number of AF494508 by GenBank. The mRNA expression of GDDM in gastric carcinoma tissue (4.496+/-0.637) was significantly lower than that in the counterpart normal gastric mucosa (36.919+/-6.290)(P<0.01). Chromosomal location of GDDM gene was at 4q31.

CONCLUSIONThe cloned novel gene, GDDM, is down-regulated in gastric carcinoma, and it is likely to be involved in gastric tumorigenicity.

OBJECTIVETo evaluate the effects of cyclosporine A (CsA) whole-blood concentration on the early response to immunosuppressive therapy (IST) in severe and very severe aplastic anemia (SAA/VSAA).

METHODSNinety SAA/VSAA patients treated with rabbit antithymocyte globulin (ATG) plus CsA as first line therapy in our hospital were retrospectively analysed. CsA levels between the response group and non-response group, and response rates of patients with variant CsA levels were compared respectively.

RESULTS(1) There was no significant difference in the beginning unmodified CsA blood concentration between IST responded and non-responded SAA/VSAA patients. The beginning unmodified C(0) 133.91 ug/L in IST 2-month responders was higher than that of 49.9 ug/L in non-responded SAA patients (P = 0.009); (2) The mean CsA C(0) and C(2) levels during the third month following IST were significantly different in responders and non-responders(197.52 µg/L vs 161.49 µg/L, P = 0.024, and 738.76 µg/L vs 615.46 µg/L, P = 0.009), and no significant difference in other periods of IST (P > 0.05); (3) The response rate (87.5%) was significantly higher in patients with CsA C(0) ≥ 200µg/L the third month following IST than those of 55.6% in patients with CsA C(0) 150 - 200 µg/L (P = 0.023) and 59.3% in patients with CsA C(0) < 150 µg/L (P = 0.046), respectively. The response rate was significantly higher of C(2) ≥ 700 µg/L group than that of C(2) < 700 µg/L group (80.5%vs 55.3%, P = 0.012).

CONCLUSIONSThe CsA concentration related to the early IST response. The third month CsA concentrations was the most important for the response and maintaining CsA levels with C(0) ≥ 200 µg/L and C(2) ≥ 700 µg/L may improve the response to IST in SAA/VSAA.

Biochemistry is not only a basic course for biology majors, but also one of the fastest growing frontier courses. Facing the complicated system of biochemistry, the traditional teaching mode exposes many problems, and the teaching effect is not good. With the development of Internet technology, " Internet +" education has developed rapidly. Online courses such as MOOCs and micro-courses provide many colleges and universities with rich learning resources. Online courses such as Dingding Classroom, Tengxun Classroom, Rain Classroom, and WeChat exchange platform also allow students to achieve synchronous learning conveniently. Online teaching has become the main teaching mode of colleges and universities across the country during the COVID-19 epidemic. However, after several years of promotion, pure online teaching has also exposed many problems in terms of teaching effect. In order to give full play to the respective advantages of online and offline teaching, blended teaching has become a new direction. South China Agricultural University began to cooperate with Wisdom Tree Platform in early 2019 to establish the MOOC of biochemistry. During the COVID-19 outbreak in 2020, the online mixed teaching mode of “MOOC + online meet course” is used in teaching. Teaching feedback results showed that "MOOC + online meet course" can be more generally recognized by students than relying solely on MOOC learning. This teaching mode improves students′ learning interest and initiative, improves teaching quality and learning effect, and provides a reference for the application of "MOOC + offline course" in the future.

This article analyzed the medical records of two patients with Vibrio vulnificus primary sepsis who were admitted to the First Affiliated Hospital of Naval Medical University and reviewed the latest literature. On November 6, 2019, a 54-year-old male patient was admitted to the hospital. The patient's lower limbs were red, swollen, and painful with ecchymosis and hemorrhagic bullae after he ate freshwater products. The emergency fasciotomy was performed 3 h after admission, and the multiple organ failure occurred after operation. The patient was given up treatment 24 h after admission. On August 12, 2020, a 73-year-old male patient was admitted to the hospital. He was in shock state on admission and had hemorrhagic bullae on his right lower limb after he ate seafood. At 3 h post admission, he underwent emergency surgical exploration and amputation of right thigh. Six days later, he received negative pressure wound treatment on the stump. On the 13^th day post admission, his families forgo the active treatment and he died 15 d after admission. The two cases were both failed to be diagnosed at the first time, and the disease progressed rapidly. Necrotizing fasciitis and multiple organ failure occurred. After the diagnosis was confirmed, timely fasciotomy and high amputation were performed respectively. The microbiological examinations both reported Vibrio vulnificus. Although the 2 cases were not cured successfully, the course of disease and some indexes of patient with early amputation were better than those of patients with fasciotomy. Vibrio vulnificus is widely distributed and frequently detected in fresh water products. The pathogenic pathway is fuzzy and complex, and it is easy to be misdiagnosed. It is necessary to establish the treatment process of Vibrio vulnificus sepsis. Early and aggressive surgical intervention should be carried out as soon as possible, fasciotomy and debridement should be thorough, and the patients with hemorrhagic bullae should be amputated early. Postoperative comprehensive measures are also important for improving the survival rate of patients.
