Abstract
In the present study, clinical manifestations of two Chinese Okihiro syndrome families were analyzed, and genetic detections were performed on the two probands by exome sequencing and verified by Sanger sequencing for family members to determine the biological pathogenesis. Prenatal diagnoses were provided for three high-risk fetuses. The affected members exhibited a wildly spectrum of phenotypes, including ultrasound abnormalities of skeletal system (radius deformity and abnormal posture), and cardiac system (persistent common arterial trunk and ventricular septal defect) in the prenatal period of family 1, the severe phenotypes (grossly shortened and deformed forearm, Duane's anomaly and hearing loss), and the mild ones (usually only thenar dysplasia, or short radius styloid process). Two SALL4 variants, c.844delC p.(Q282Kfs*8) and c.2210delG p.(G737Vfs*23), have been identified respectively in two probands, and c.2210delG of SALL4 gene was unreported previously. The two variants were verified in all affected individuals, not in normal family members. Genotyping results of three fetuses indicated that one fetus was normal, and the two fetuses with heterozygous variation were affected. The two variants of SALL4 gene, c.844delC p.(Q282Kfs*8) and c.2210delG p.(G737Vfs*23), were the molecular pathological cause of Okihiro syndrome in the present study and enriched the spectrum of SALL4 variants. Our study provides accurate prenatal genetic diagnosis for the two families to avoid the birth of affected children.

Abstract
To evaluate the clinical value of emergency endovascular embolization in the interventional treatment for oral hemorrhage caused by carcinoma, 32 patients with oral hemorrhage caused by carcinoma, who received emergency endovascular embolization due to unsatisfactory hemostatic effect of conventional conservative treatment in the First Affiliated Hospital of Zhengzhou University from January 2014 to December 2019, were included in this study and their clinical data, laboratory data and imaging information were retrospectively analyzed. There were 16 males and 16 females, aged (60.6±13.6) years (34-88 years). Technical successful rate of emergency endovascular embolization, immediate successful rate of controlling hemorrhage, blood pressure before and after operation, hemoglobin before and after operation, postoperative complications and recurrence rate of oral hemorrhage were statistically analyzed. Results showed that technical successful rate of operation and immediate successful rate of controlling oral hemorrhage are both 100% (32/32). Recurrent oral hemorrhage occurred in 4 patients (13%). The hemorrhagic shock symptoms of all patients were significantly improved after interventional therapy. After operation, local swelling happened in 34% (11/32) patients and intermittent local pain happened in 22% (7/32) within 24 hours; the swelling and the pain gradually disappeared from 2nd to 5th days. Mild complications of transient fever happened in 9% (3/32) patients and disappeared spontaneously in the short term. No serious complications such as blindness, cerebrovascular accident or central nervous system disturbance occurred in all patients after operations. During the whole follow-up period (1 to 12 months), a total of 8 patients died. The causes of death were progression and metastasis of carcinoma (n=4), heart failure (n=2), severe pneumonia (n=1) and respiratory failure caused by recurrent oral hemorrhage (n=1). Owing to the remarkable short-term curative effect, repeatable operation, low recurrence rate of oral hemorrhage and low incidence of complications, emergency endovascular embolization can be used in the clinical therapy and application of oral hemorrhage caused by carcinoma.

Abstract
Objective: To assess the feasibility and value of real-time image fusion technique guiding the procedure of transjugular intrahepatic portosystemic shunt(TIPS). Methods: From July 2017 to May 2018,a total of 48 consecutive patients complicated by portal venous hypertension due to cirrhosis who underwent TIPS were prospectively allocated into two groups that 27 cases underwent normal TIPS and 21 cases underwent image fusion guided TIPS. There were 25 males and 23 females with a mean age of 29-74(51±10) years. The differences of portal vein(PV) between image fusion angiographyand digital subtraction angiography(DSA), and the times of puncture PV, X-ray exposure dose and exposure time and contrast agent amount of all cases were collected and analyzed. Results: The longitudinal and traverse difference of PV between image fusion angiography and DSA were 1.7-2.5(2.1±0.2) mm and 0.9-1.8(1.4±0.3) mm, respectively.The times of puncture PV, X-ray exposure time and dose, and contrast agent amount between normal TIPS group and image fusion guided TIPS group were 1-7(3.8±0.6) times vs 1-3(2.0±0.6) times, 41-63(53±8)min vs 27-42(35±5) min, 513-787(644±96) mGy vs 357-524(423±59) mGy,102-196(151±23) ml vs 87-145(105±14) ml(all P<0.05), respectively. Conclusions: There are minor differences between image fusion angiography of PV and DSA. Real-time image fusion guided TIPS is feasible and valuable to reduce intraprocedural X-ray exposure time and dose and contrast agent amount of TIPS.

Abstract
Objective: To investigate the effect of interleukin (IL)-7 on anti-tumor activity of CD8(+) T cells in non-small cell lung cancer (NSCLC) patients. Methods: Twenty-seven NSCLC patients and ten healthy controls were included from Zhengzhou Central Hospital between January 2017 and July 2017. Plasma, peripheral blood mononuclear cells (PBMCs), and bronchial alveolar lavage fluid (BALF) (both tumor site and non-tumor site) were collect from NSCLC patients, while plasma and PBMCs were also collected from healthy controls. IL-7 level and IL-7 receptor α (CD127) mRNA relative expression was measured. Purified CD8(+) T cells and primary NSCLC cells were stimulated with recombinant IL-7. Cellular proliferation, cytokines secretion, and protein expression in IL-7 signaling pathway were investigated. Direct/indirect contact coculture system of CD8(+) T cells and primary NSCLC cells was also used to assess the cytolytic and noncytolytic activity after IL-7 stimulation. Results: Plasma IL-7 level was significantly reduced in NSCLC patients compared with normal controls[1 731 (1 364, 2 536) vs 2 686 (1 692, 4 786) ng/L, P=0.023). IL-7 level in BALF isolated from tumor site was also remarkably down-regulated compared with non-tumor site in NSCLC patients[1 045 (562, 1 550) vs 1 599 (1 166, 2 107) ng/L, P=0.006 9). There was no statistical difference of CD127 mRNA between the two groups. Recombinant IL-7 stimulation did not affect cellular proliferation and cytokines production in primary NSCLC cells, however, remarkably increased cellular proliferation, interferon (IFN)-γ/tumor necrosis factor (TNF)-α secretion, and signal transducers and activators of transcription 5 (STAT5) phosphorylation and suppressor of cytokine signaling 3 (SOCS3) expression of CD8(+) T cells from NSCLC patients. IL-7 stimulation also significantly enhanced the cytolytic and noncytolytic function of CD8(+) T cells on primary NSCLC cells. Conclusion: IL-7 enhances anti-tumor activity of CD8(+) T cells in NSCLC patients.

Abstract
AIM To evaluate the safety and feasibility of enhanced recovery after surgery (ERAS) for total laparoscopic uncut Roux-en-Y gastrojejunostomy after distal gastrectomy.
METHODS The clinical data of 42 patients who were divided into an ERAS group (n = 20) and a control group (n = 22) were collected. The observed indicators included operation conditions, postoperative clinical indexes, and postoperative serum stress indexes. Measurement data following a normal distribution are presented as mean ± SD and were analyzed by t-test. Count data were analyzed by χ2 test.
RESULTS The operative time, volume of intraoperative blood loss, and number of patients with conversion to open surgery were not significantly different between the two groups. Postoperative clinical indexes, including the time to initial anal exhaust, time to initial liquid diet intake, time to out-of-bed activity, and duration of hospital stay of patients without complications, were significantly different between the two groups (t = 2.045, 8.685, 2.580, and 4.650, respectively, P < 0.05 for all). However, the time to initial defecation, time to abdominal drainage-tube removal, and the early postoperative complications were not significantly different between the two groups. Regarding postoperative complications, on the first and third days after the operation, the white blood cell count (WBC) and C reactive protein (CRP) and interleukin-6 (IL-6) levels in the ERAS group were significantly lower than those in the control group.
CONCLUSION The perioperative ERAS program for total laparoscopic uncut Roux-en-Y gastrojejunostomy after distal gastrectomy is safe and effective and should be popularized. Additionally, this program can also reduce the duration of hospital stay and improve the degree of comfort and satisfaction of patients.

Abstract
This study aimed to investigate the correlation between age-related macular degeneration (AMD) of the liver-kidney yin-deficiency type and complement factor H (CFH) polymorphism, and to determine whether the C allele of the T1277C (Y402H) variant is a risk factor for this condition. We performed a case-control investigation of 60 patients with liver-kidney yin-deficiency AMD and 60 normal control subjects. Peripheral blood was collected from each participant for DNA extraction. Following amplification by polymerase chain reaction, the DNA samples were sequenced, and polymorphism of the CFH gene was examined. Data were analyzed with the chi-square test, with P < 0.05 signifying statistical significance. The frequency of the C allele was significantly higher in the wet than in the dry AMD group (P = 0.044). In addition, the TC and CC genotypes were markedly more common in the former than in the control group (P = 0.013), and there was a significant difference in the distribution of the T and C alleles between wet AMD patients and control subjects (P < 0.05). Based on this, we conclude that liver-kidney yin-deficiency AMD is associated with the C allele and TC and CC genotypes of the CFH Y402H polymorphism. Among patients with this condition, CFH genotypes were normally distributed. The principal CFH genotypes that induce liver-kidney yin-deficiency AMD are the mutant homozygote CC and heterozygote TC forms. Moreover, C allele carriers are at higher risk of developing this disease.

Abstract
OBJECTIVE To evaluate the prognostic value of combination of plasma brain natriuretic peptide(BNP) with the ratio of early diastolic mitral inflow velocity to early diastolic mitral annulus velocity(E/E') in the patients with septic shock. METHODS From June 2012 to December 2013 , 127 patients with septic shock were consecutively recruited and underwent trans-thoracic echocardiography examination within 6 h after admission to Intensive Care Unit(ICU), Zhejiang Provincial People's Hospital. Plasma BNP concentration was measured using ELISA method. All Clinical, laboratory, and survival data were prospectively collected. RESULTS Of 127 patients enrolled, mean values for age were(59.9±17.3) years and APACHE Ⅱ score(16.8±5.8), respectively. 95 patients(74.8%) took mechanical ventilation. 28- , 60-day mortality rate was 36.3% and 42.3%, respectively. Univariate Cox regression analysis showed that age, coronary artery disease, serum creatinine and lactate, plasma BNP, left ventricular ejection fraction(LVEF), E/E' and APACHE Ⅱ score were significantly(P≤0.05) associated with 60-day mortality. Multivariate analysis revealed that serum lactate, plasma BNP(χ(2)=9.4, P=0.002) , E/E'(χ(2)=4.89, P=0.02) and APACHE Ⅱ score(χ(2)=10.6, P=0.001) remained independent predictors for 60-day mortality. ROC curve analysis showed that the optimal plasma BNP and E/E' cutoff values identified were 338.8 pg/ml and 10.8, and the areas under ROC curve were 0.89(sensitivity: 83.7%; specificity: 81.4%)and 0.83(sensitivity: 76.7%; specificity: 72.9%)for 60-day mortality, respectively. In addition to plasma BNP and clinical predictors, the E/E' could provide in independent and incremental prognostic value of 60-day mortality(χ(2)=59.3 vs 47.8, P<0.001). CONCLUSION Plasma BNP and E/E' are independent predictors for 60-day mortality, and combination of plasma BNP and E/E' could improve risk stratification in patients with septic shock.

Abstract
Cystoid macular edema (CME), a commonly seen sign for multiple fundus diseases, is able to induce visual deterioration. The incidence rate of CME is constantly increasing; however, the existing clinical treatments cannot achieve satisfactory curative effects. To explore the curative effect of intravitreous injection of triamcinolone acetonide (TA) in treating CME, this study carried out a clinical test on 39 patients (42 eyes) from The First Affiliated Hospital of Zhengzhou University who developed CME induced by central retinal vein occlusion (CRVO). All 42 eyes received intravitreous injection of 40 mg/ml TA (0.1 ml) and then were followed up for 11-23.5 months. Eyes were examined by slit-lamp microscope, fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) and best corrected visual acuity (BCVA), and intraocular pressure (IOP) of those eyes were detected before and after treatment. Average vision of eyes was 0.1 before treatment, and the vision improved in one month (vision ≥ 0.2: 100%; vision ≥ 0.5: 42.9%) and three months (vision ≥ 0.2: 64.3%; vision ≥ 0.5: 21.4%) after treatment; but as time went on, the vision of some patients declined; at the last follow-up, patients with vision ≥ 0.2 accounted for 28.6% and those with vision ≥0.5 accounted for 7.1%; compared to before treatment, 71.4% patients had improved vision and the remaining 28.6% had declined vision. Some patients were observed with high IOP during treatment, and 7 eyes were found with secondary cataract in posterior capsule of lens at the last follow-up. Intravitreous injection of triamcinolone acetonide proved to have significant short-term curative effect on CEM which is non-sensitive to conventional therapies, but it is likely to induce high IPO and posterior capsular opacification.

Abstract
AIM AND METHODS Oxygen consumption of gastrocnemius in rats of frostbite at normoxia (FN), frostbite during acute hypoxia (FAH) and frostbite during hypoxia after hypoxic acclimation (FHAC) groups was investigated with a system of oxygen consumption measurement before and after the rats' right hind legs were frozen in order to provide theoretical data for exploring the reasons that hypoxic acclimation could aggravate tissue damage of animals wth frostbite. RESULTS Before freezing, oxygen consumption of gastrocnemius in rats of FHAC group decreased by 26.2%. At the first day after freezing, oxygen consumption of gastrocnemius in rats of FN, FAH and FHAC groups was 5.93 +/- 0. 66, 4.74 +/- 1.87 and 0.76 +/- 0.39 [kPa/(g x min)], and decreased by 76.3%, 77.9% and 95.9% respectively as compared with themselves before freezing, and that of FHAC group was much lower than those of FN and FAH groups. At the fifth day after freezing, oxygen consumption of gastrocnemius of the three groups returned to 62.8%, 44.9% and 28.8% of those themselves before freezing respectively, and that of FHAC group was much smaller than those of FN and FAH groups, showing that post-frostbite metabolic rate of skeletal muscle of rats acclimated to hypoxia decreased further and restored much slowly. CONCLUSION Both hypoxic acclimation and frostbite could decrease the oxygen consumption of gastrocnemius in rats, the complex of those two effects on oxygen consumption made the oxygen consumption to decrease further, suggesting that the changes in tissue metabolism could be one of the main factors that affected the degree of tissue damage and recovery.

Abstract
Correlations were examined between habitat characters and clonal structures determined by the RAPD (random amplified polymorphic DNA) assay in five populations of Oryza rufipogon in China. Nine of 175 decameric primers were used in the study because they reproducibly amplified polymorphisms. The extent of clonality together with the clonal and sexual reproductive strategies varied greatly among the five populations and correlated with the habitats where they occur. The populations under serious disturbance or seasonal drought tended to have small clones with relatively high clonal diversity caused by sexual reproduction, whereas the populations with little disturbance and sufficient supply of water were prone to have large clones with relatively low clonal variation and low sexual reproduction. Therefore, the dynamics of sexual vs. clonal reproduction of this species depended mainly on environmental factors, such as external disturbance and water supply, rather than latitudes indicated by previous study. These results have important implications for in situ conservation of O. rufipogon. Adequate external disturbance and water supply control are essential for maintaining high clone diversity of in situ conserved populations. According to the extent of clonality of the populations examined, we recommend that an interval of >12 m should be required for collecting samples for ex situ conservation and for population genetic studies to capture possible genetic diversity for O. rufipogon in China.

Abstract
AIM To correlate the injury of vascular endothelial cells during various pathological conditions with the change of vWF (von Willebrand Factor) in different VEC lines. METHODS Flow cytometer(FCM) were used to defect the immunoflourescent stained vWF in pulmonary artery endothelial cells (PAEC) of pig and aortic endothelial cells(AEC) of rats. RESULTS The positive rates of vWF in PAEC of pigs is similar with that in AEC of rats under normal condition, but it decreased differently after hypoxic or cold injury. It was very interesting that the mean fluorescence intensity of positive PAEC or AEC exposed to hypoxia or cold elevated significantly compared with those of control. CONCLUSIONS The change of vWF in VEC can be used to evaluate the function of VEC under different stress.

Abstract
AIM To study the structure-activity relationship of Torpedo acetylcholinesterase (AChE) and explore whether the anionic subsite of the active center is a constituent of the conformational epitope of enzyme. METHODS Using ELISA and enzyme inhibition test to examine the effect of 1-methyl-2-hydroxyiminomethylpyridium chloride (2-PAM), an anionic subsite probe of AChE, on the immunoreactivity between Torpedo AChE and its monoclonal antibody (McAb) 3F3. RESULTS McAb 3F3 did not react with 2-PAM-AChE complex. 2-PAM decreased the inhibitory rate of McAb 3F3 on AChE in a concentration-dependent fashion, but did not dissociate the McAb 3F3-AChE complex. CONCLUSION Anionic subsite of the active center of Torpedo AChE constructs a part of its conformational epitope.

Abstract
AIM To study the type of epitope of native Torpedo acetylcholinesterase (AChE) directed by its monoclonal antibody (McAb) 3F3. METHODS Enzyme-linked immunosorbent assay (ELISA) was used for the assay of the reaction between antigen and antibody. RESULTS McAb 3F3 immunoreacted well with the native AChE, but not with the reduced- and alkylated-AChE (RA-AChE) at all. Soman did not interfere the binding of 3F3 with AChE molecule. The synthesized 24-peptide containing the active serine residue of the AChE active center did not react with McAb 3F3. CONCLUSION 3F3 is a monoclonal antibody against the conformational epitope of Torpedo AChE active center, but dose not occupy the active serine residue of the enzyme.

Abstract
Human Pro-Urokinase (Pro-UK) is expressed in CHO-DHFR- cells at high efficiency by co-transfecting the mouse dhfr gene and Pro-UK cDNA under the control of the SV40 late promoter. After gene co-amplification, the product level could reach 2-3 micrograms/10(6) cells/24 h in the presence of 5 x 10(-6) mol/L MTX, and the levels can be further raised to 3.5-4 micrograms/10(6) cells/24 h by PMA superinduction. The copy number of Pro-UK cDNA in the genomes of host cells is about 200-300 copies/cell. The Western blot analysis shows that the recombinant Pro-UK has similar molecular weight to its natural counterpart, and also the amidolytic activity of the product is determined by S-2444 assay.

Abstract
The red cell C3b receptor activity of 52 patients with esophageal cancer, 19 patients with cancer of gastric cardia and 31 age-matched normal persons was studied by the ability of forming ZC3b-rosette (rosette formation with zymosan particles treated by guinea pig complement) and IC-Z rosette (rosette formation with zymosan particles). The results showed that the ZC3b-rosette formation rate was significantly lower in cancer patients than that of the normal subjects (P less than 0.01), but the IC-Z rosette formation rate was significantly higher in the cancer patients (P less than 0.01). This suggests that the esophageal cancer and cancer of gastric cardia be associated with surface changes in the erythrocytes, especially those of the receptors which are responsible for immune adherence reaction. The methods of detecting the red cell C3b receptor are also described.
