Abstract
Objective: To analyze the physical growth of preterm infants with different intrauterine growth patterns. Methods: A total of 10 856 preterm infants who were born in various districts of Haikou City from October 1st, 2015 to June 1st, 2021 and received regular health care and management were retrospectively enrolled. The preterm infants were divided into appropriate for gestational age (AGA), small for gestational age (SGA) and large for gestational age (LGA) groups according to different intrauterine growth patterns. The general characteristics of preterm infants in different groups were compared by H test (Kruskal and Wallis) or Chi-squared test. And the developmental curves were plotted by local regression (LOESS) with their physical growth indexes. Results: Of the 10 856 preterm infants, 6 317 were boys and 4 539 were girls. The gestational age at birth was 35 (34, 36) weeks, and the birth weight was 2.5 (2.1, 2.8) kg. There were 754 (6.9%) SGA, 9 301 (85.7%) AGA, and 801 (7.4%) LGA preterm infants. All preterm infants were followed up until 18 months of corrected age. The birth weight of the SGA group was lower than that of the AGA and LGA groups (Z=2 274.93, P<0.001). The proportion of exclusive breastfeeding at the first health care interview was higher in the AGA group (68.6% (6 378/9 301)) than in the SGA group (62.9% (474/754)) (χ2=13.82, P=0.003). The LOESS curving fitting showed that the weight and height of the preterm infants in all the 3 groups increased rapidly during 0-6 months of corrected age. The regression prediction values of weight for age Z-score (WAZ), height for age Z-score (HAZ) and weight for height Z-score (WHZ) were around 0 s, while the regression prediction values of these three indicators in SGA were all below 0 s but greater than -1 s. The rates of low birth weight, growth retardation and wasting during 0-17 months of corrected age were 0.3% (16/4 838)-1.9% (47/2 506), 0.4% (18/4 838) -2.4% (51/2 124), and 2.1% (88/4 135) -4.4% (214/4 838) in AGA groups, and 0 (0/296) -1.0% (2/199), 0 (0/341) -1.6% (3/186) and 1.0% (2/199) -2.6% (9/341) in LGA group, whereas 7.6% (25/330) -16.8% (28/167), 5.2% (17/330)-10.6%(32/303) and 3.9% (3/77) -12.6% (21/167) in SGA group. In addition, the monthly growth of weight and height of preterm infants in all the 3 groups decreased with the increasing age, and the monthly weight gain. The length increment was 4.0 cm/month during corrected 0-2 month of age and 2.4 cm/month during corrected 2-5 month of age in the SGA preterm infants. Conclusions: Most of the preterm infants could have an appropriate catch-up growth, but the growth and development in the SGA preterm infants lags behind that of their AGA and LGA peers. The physical growth of SGA premature infants should be paid more attention to, to timely correct the growth deviations.

Abstract
The aim of this paper was to investigate the effect of Schizonepetae Herba and Saposhnikoviae Radix(wind medicine) on the expression of AQP4 and AQP8 in colonic mucosa in rats with ulcerative colitis(UC). A total of 35 healthy SD male rats were randomly divided into normal group(gavaged with normal saline), DSS model group, as well as low, middle, and high dose wind medicine groups(Schizonepeta and Saposhnikovia 1∶1, gavaged at dosages of 6, 12, and 24 g·kg~(-1)·d~(-1)), with 7 in each group. UC rat model was established by free drinking of 3% dextran sulphate sodium(DSS) solution for 10 days. At the end of the 10 th day after the treatment, mice were put to death to collect colonic mucosa. The length of colon was measured; the colonic mucosal injury index(CMDI) and pathological changes of colon were observed. ELISA method was used for measuring the content of serum IL-1, IL-8, and immunohistochemical method was used to measure AQP4, AQP8 protein expressions in colon mucosa. The expressions of AQP4, AQP8 mRNA were measured by Real-time PCR. As compared with the normal group, the length of colon tissue was significantly reduced(P<0.01), CMDI scores and pathological scores were significantly increased(P<0.01), the levels of serum IL-1 and IL-8 were significantly increased(P<0.05) in model group; the immunohistochemical results showed that the protein expressions of AQP4, AQP8 were lower; the color was light yellow or brown; AQP4, AQP8 mRNA expressions in colon mucosa were significantly decreased in model group(P<0.01). CMDI scores, pathological scores, and the levels of serum IL-1, IL-8 in high, middle, low dose wind medicine groups were obvious lower than those in the model group(P<0.01 or P<0.05); the protein expressions of AQP4, AQP8 were higher; the color was chocolate brown or dark brown; the length of colon tissue, and the expressions of AQP4, AQP8 mRNA were obvious higher in wind medicine groups(P<0.01 or P<0.05). Schizonepetae Herba and Saposhnikoviae Radix could significantly improve the symptoms and histopathology of UC model rats and accelerate the intestinal mucosal healing. The mechanism may be related with up-regulating the expression level of AQP4 and AQP8 in colonic mucosa.

Abstract
The aim of this paper was to screen the active targets of Schizonepetae Herba and Saposhnikoviae Radix in the treatment of ulcerative colitis by means of network pharmacology,and to investigate their mechanism of action. The effective components of Schizonepetae Herba and Saposhnikoviae Radix were screened out by traditional Chinese medicine systematic pharmacological( TCMSP)database,with oral bioavilability( OB) ≥30% and drug-like( DL) ≥18% selected as the thresholds. Target PPI network was built between the main components and their corresponding targets. One hundred and eighty-two human genes corresponding to the medicine target sites were obtained from Uniprot database; 3 874 genes corresponding to ulcerative colitis were obtained from Genecard database.A total of 115 intersection genes were screened from disease genes and medicine genes,and the PPI interaction analysis was conducted by using String tool. Disease-target PPI network was drawn by using Cytoscape software,and component-target-disease network was constructed. One hundred and eight nodes and 1 882 connections were found,and then Cytoscape software was used to merge the networks and filter the core network for gene GO function analysis and KEGG pathway enrichment analysis. The mechanism of Schizonepetae Herba and Saposhnikoviae Radix was then verified by animal experiment. Gene GO functional analysis suggested that biological process,molecular functions and cell components were involved,and it was found that ulcerative colitis might be related to transcription factor activity,and cytokine receptor binding,etc. Gene KEGG pathway enrichment analysis showed that the mechanism of ulcerative colitis might be associated with TNF and Toll-like receptors( TLRs) signaling pathway-mediated cytoinflammatory factors interleukin-1( IL-1) and interleukin-6( IL6). The possible mechanism of the effective components of Schizonepetae Herba and Saposhnikoviae Radix in treating ulcerative colitis might be related to intervening the cytokine receptor binding of TNF and TLRs signaling pathways,reducing the transcription of nuclear factor-kappaB( NF-κB),and inhibiting the secretion of intestinal inflammatory factors IL-1 and IL-6.

Abstract
BACKGROUND Cavernous hemangiomatosis in the liver and spleen has been reported, but it occurs less commonly in the peritoneum. Here we report a case of peritoneal cavernous hemangiomatosis and share some valuable information about this disease.
CASE SUMMARY A 57-year-old Chinese man had a huge abdominal mass with abdominal distention and a significant reduction of food consumption. An enhanced abdominal and pelvic computed tomography and positron emission tomography–computed tomography revealed multiple cystic masses on the peritoneum, greater omentum, small intestinal mesentery and the surface of the spleen, and a high maximum standardized uptake value of the largest cystic lesion. Exploratory laparotomy was performed, and multiple cystic masses were found on the surface of the peritoneum, greater omentum, mesentery of the small intestine, and surface of the liver and spleen. Dark red bloody cystic fluid was present in the cystic tumor. Pathological examination showed that in the stromal components, the irregular vascular wall was thin. The vessel lumen was interlinked, and the lumen was lined with flat endothelium. According to the intraoperative findings and pathologic results, the patient was diagnosed with peritoneal cavernous hemangiomatosis.
CONCLUSION The possibility of peritoneal cavernous hemangiomatosis should be considered when multiple cystic masses are found in the abdominal cavity by preoperative examination.

Abstract
Circular RNA is a class of non-coding RNAs, which are covalently closed and circular at both ends, showing dissimilar characteristics from linear RNA. Several studies have shown that circular RNAs play an important role in the occurrence and development of primary hepatic cancer. By combining with the latest research progress of this field at home and abroad, we summarized the mechanism regulating the occurrence and development of liver cancer, abnormal expression, and as potential molecular markers for disease diagnosis and treatment.

Abstract
We herein report a rare case of ileal bronchogenic cyst that was found in a 39-year-old Chinese man. He had no symptoms and the physical examination was normal. Tumor markers were within the normal range. Abdominopelvic enhanced computed tomography showed a mass in the lower abdominal cavity and the tumor had a complete capsule. Diagnostic laparoscopy was then performed, which showed that a spheroid mass with a complete capsule was located at the antimesenteric border of the distal ileum 20 cm from the ileocecal valve, measuring 6.0 cm × 6.0 cm × 5.0 cm. Considering that the malignancy of the tumor cannot be ruled out, and there is a risk of rupture during laparoscopic surgery, the patient was converted to an open surgery. Partial resection of the ileum with the tumor was performed, followed by a side-to-side anastomosis. The tumor was gray-red in color, filled with grayish yellow mucus and had no septum. The postoperative pathology revealed that the cystic wall was lined by pseudostratified ciliated columnar epithelium without cellular atypia. The wall consisted of bronchial mucous glands and smooth muscle fibers, and no abnormalities were found in adjacent ileum tissues. Thus, a diagnosis of bronchogenic cyst of the ileum was made.

Abstract
The aim of the present study was to evaluate the add-on effect of acarbose therapy in oxidative stress, and the lipid and inflammatory profiles of patients with type 2 diabetes mellitus (T2DM) treated with insulin. This was an open and unblended study. Patients (n=134) with T2DM (haemoglobin A1c range, 9.0-12.0%) were recruited. After continuous subcutaneous insulin infusion for 7 days for initial rapid correction of hyperglycaemia, a premixed insulin titration period (duration, 4-6 days) subsequently followed. Patients were then randomized (1:1) into two groups as follows: An acarbose plus pre-mixed 30/70 insulin group or a pre-mixed 30/70 insulin only group; each group received treatment for 2 weeks. Plasma high-sensitivity C-reactive protein (Hs-CRP), 8-iso-prostaglandin F2α (8-iso PGF2α), tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-6 levels were measured before and after therapy. Patients that received acarbose plus insulin demonstrated greater reduction in 8-iso PGF2α, Hs-CRP, TNF-α, IL-1β and IL-6 levels when compared with the insulin only patients. Thus, acarbose add-on insulin therapy was identified to be associated with greater improvements in oxidative stress and inflammation in patients with T2DM when compared with those that received insulin only therapy.

Abstract
In this study, petrochemical secondary effluent was treated by a 55 cm diameter pilot-scale biological aerated filter (BAF) with a media depth of 220 cm. Volcanic rock grains were filled as the BAF media. Median removal efficiency of chemical oxygen demand (COD) and ammonia nitrogen (NH3-N) was 29.35 and 57.98%, respectively. Moreover, the removal profile of the COD, NH3-N, total nitrogen and total organic carbon demonstrated that the filter height of 140 cm made up to 90% of the total removal efficiency of the final effluent. By gas chromatography-mass spectrometry, removal efficiencies of 2-chloromethyl-1,3-dioxolane, and benzonitrile, indene and naphthalene were obtained, ranging from 30.12 to 63.01%. The biomass and microbial activity of the microorganisms on the filter media were in general reduced with increasing filter height, which is consistent with the removal profile of the contaminants. The detected genera Defluviicoccus, Betaproteobacteria_unclassified and the Blastocatella constituted 1.86-6.75% of the identified gene, enhancing the COD and nitrogen removal in BAF for treating petrochemical secondary effluent.

Abstract
ABSTRACT Ordinal qualitative data are often collected for phenotypical measurements in plant pathology and other biological sciences. Statistical methods, such as t tests or analysis of variance, are usually used to analyze ordinal data when comparing two groups or multiple groups. However, the underlying assumptions such as normality and homogeneous variances are often violated for qualitative data. To this end, we investigated an alternative methodology, rank regression, for analyzing the ordinal data. The rank-based methods are essentially based on pairwise comparisons and, therefore, can deal with qualitative data naturally. They require neither normality assumption nor data transformation. Apart from robustness against outliers and high efficiency, the rank regression can also incorporate covariate effects in the same way as the ordinary regression. By reanalyzing a data set from a wheat Fusarium crown rot study, we illustrated the use of the rank regression methodology and demonstrated that the rank regression models appear to be more appropriate and sensible for analyzing nonnormal data and data with outliers.

Abstract
OBJECTIVE The study aims to explore the prevalence and clinical features of fulminant type 1 diabetes mellitus (F1DM). SUBJECTS AND METHODS We analyzed 11,202 patients who were diagnosed having diabetes and admitted to the Department of Endocrinology, Nanjin First Hospital, Nanjin, China, from September 2005 to April 2011. Among 198 patients classified having type 1 diabetes mellitus (T1DM), nine patients were diagnosed having F1DM. Clinical features of F1DM were analyzed and compared with typical T1DM. RESULTS The prevalence of F1DM was 4.5% (nine of 198 T1DM patients) in this study. F1DM patients had significantly high levels of random blood glucose (40±9 mmol/L). However, glycated hemoglobin (7.1±1.0%) and C-reactive peptide (0.21±0.15 μg/L) at 2 h postprandial were significantly lower in F1DM patients compared with typical T1DM patients. Six of them had flu-like symptoms. Five of them showed gastrointestinal symptoms. Three patients experienced disturbance of consciousness. However, none of these symptoms was found in patients with typical T1DM. A continuous intravenous insulin infusion therapy using a portable pump was given during the acute phase to control hyperglycemia and ketoacidosis. All F1DM patients survived after treatment. CONCLUSION In this single hospital-based study, nine Chinese patients met the criteria for diagnosis of F1DM. Although F1DM may be fatal, prompt treatment is required and useful to rescue these patients.

Abstract
A two-stage SBR system treating the wastewater containing copper-phthalocyanin dye-Reactive Turquoise Blue KN-G (C. I. Reactive Blue 21, denoted by RTB) was investigated during a 200-cycle operation. The performance of the system, including pollutant removal rates, operating stability and sludge characteristics, may be a concern in the long-term run. The results shows that the system removed RTB efficiently despite the step-up RTB concentration from 13.1 to 107 mg/L in the influent. The average total removal rates of RTB were 81% to 92.5% due to the contribution of both anaerobic and aerobic stages, while stable effluent was produced with the help of the aerobic stage. The sludge in each reactor was in the steady state and of good activity on RTB removal. Moreover, the anaerobic sludge with the SVI value of 109.1 and the aerobic sludge with the SVI value of 103.2 had good settling properties, which was verified by hardly any presence of suspended solids in the effluent and an observation under an electron-scanning microscope. The adsorption and biodegradation were considered as the mechanism for the stability of the SBR system during the long-term run.

Abstract
AIM To investigate the effects of a sea anemone toxin anthopleurin-Q (AP-Q) isolated from Anthopleura xanthogrammica on sodium current (INa) in isolated guinea pig ventricular myocytes. METHODS Single myocytes were dissociated by enzymatic dissociation method. INa was recorded using whole-cell patch-clamp technique. RESULTS AP-Q (3 - 300 nmol/L) increased INa in a concentration-dependent manner. The EC50 value for increasing INa was 104 nmol/L (95 % confidence range: 78 - 130 nmol/L). AP-Q 300 nmol/L shifted the I-V curve to the leftward, changed the membrane potential of half maximal activation to more negative potential from (-36.3 +/- 2.3) mV to (-43 +/- 3) mV (n = 6, P < 0.01) and changed the membrane potential of half maximal inactivation to more positive potential from (-75 +/- 6) mV to (-59 +/- 5) mV (n = 6, P < 0.01). AP-Q 300 nmol/L shortened the half-recovery time of INa from (114 +/- 36) ms to (17 +/- 2) ms (n = 6, P < 0.01). The fast inactivation time constant (tauf) of INa was markedly increased by AP-Q 300 nmol/L. CONCLUSION AP-Q has a stimulating effect on I(Na) with slowing the inactivation course of INa.

Abstract
AIM To investigate the effect of 4-aminopyridine (4-AP) on ion channels of myocytes. METHODS L-type calcium channel and sodium channel currents were recorded in guinea pig single ventricular myocyte using whole-cell patch-clamp techniques. RESULTS 4-AP, 0.1, 0.5 and 1.0 mmol.L-1 were shown to inhibit L-type calcium channel currents (ICa, L) and sodium channel currents (INa) concentration-dependently. The percentage of inhibition were (11.6 +/- 1.7)%, (37.5 +/- 8.3)% and (54.5 +/- 6.9)% (P < 0.01) respectively for ICa, L, and (22.1 +/- 14.3)% (P < 0.05), (39.4 +/- 8.8)% and (62.3 +/- 6.8)% (P < 0.01) respectively for INa. 4-AP 0.5 mmol.L-1 shifted the I-V curves of ICa, L and INa upwardly. CONCLUSION 4-AP blocked L-type calcium channel and sodium channels in guinea-pig ventricular myocytes concentration-dependently.

Abstract
OBJECTIVE To study arterial oxygen saturation (SpO2) obtained by pulse oximetry and dyspnea during active eating (AE) and passive eating (PE) in patients with severe chronic obstructive pulmonary disease (COPD). DESIGN Patients were studied on two consecutive days with AE and PE, which occurred in random order. SpO2 was recorded for 20 mins before and during eating, and dyspnea was recorded by the patient using a 10 cm visual analogue scale before and upon completion of eating. SETTING Subjects were in-patients at an intermediate care facility who were hospitalized for pulmonary rehabilitation or for convalescence after an exacerbation of COPD. POPULATION STUDIED Thirty-five patients with severe COPD (forced expiratory volume in 1 s [FEV1] less than 50% predicted, FEV1 to forced vital capacity ratio less than 65%) were studied. Mean age was 70.5 7.1 years. MAIN RESULTS Mean SpO2 decreased significantly (P<0.05) from 91.7 3.4% to 90.1 4.0% during AE, and 91.7 3.2% to 90. 8 3.6% during PE. Mean lowest SpO2 was lower and percentage of time with SpO2 less than 90% was greater during eating compared with corresponding control periods during both AE and PE. Dyspnea increased significantly (P<0.05) from 1.4 1.2 to 3.3 2.3 cm during AE, and from 1.5 1.5 to 2.4 2.2 cm during PE. The increase in dyspnea was significantly greater during AE than PE. CONCLUSIONS Eating is an activity that can adversely affect SpO2 and increase dyspnea in patients with severe COPD. Oxygen desaturation and particularly increased dyspnea may at least in part relate to the recruitment of upper extremity muscles during eating.

Abstract
BACKGROUND The number of elderly people with small cell lung carcinoma (SCLC) is increasing and currently nearly 25% are older than 70 years. Elderly patients may not tolerate intensive therapy and, therefore, often do not receive such treatment. Additionally, age may be an independent predictor for response and survival. We compared the investigation, staging procedure, and management of patients less than 60 years, 60 to 69, and older than 70 years who were diagnosed with SCLC between 1985 and 1991. We hypothesized that elderly patients were investigated and treated less aggressively, and that their outcome was poorer than that of younger patients with SCLC. METHODS Information on weight loss, performance status, coexisting disease, staging investigations, and treatment was recorded. Treatment was categorized as optimal or suboptimal using predetermined criteria, and correlated with patient age. Toxicity grade, response to treatment, and survival were noted. RESULTS There were no differences among the 3 age groups with respect to disease stage, and weight loss, although poorer performance status and comorbidity were more common in those patients older than 70 years. Elderly patients were investigated and treated less aggressively than the 2 younger patient groups. The oldest group received smaller chemotherapy dosage, fewer cycles, and had more dose reductions compared to the younger patients. Only 1 of 81 elderly patients was enrolled on an experimental protocol as compared with 19% and 28% of the younger patient groups. Furthermore, elderly patients had the highest frequency of supportive care alone. There was a significant relationship between advanced age and suboptimal treatment, with those older than 70 years having an odds ratio (OR) of 0.30 (95% confidence interval (CI) 0.15-0.61), for having received optimal treatment. Despite this, survival was similar for younger and older groups of patients (OR 0.89, CI 0.6-1.3). CONCLUSIONS Elderly patients had poorer pre-treatment performance status, greater comorbidity, were more likely to have suboptimal therapy and were almost never entered into clinical trials. Despite this their survival did not differ from that of younger patients with SCLC. Randomized trials of treatment, with assessment of quality of life, are necessary to determine the effect of modified regimens for elderly patients with SCLC.
