Estimation of Genetic Parameters for Growth and WSSV Resistance Traits in Litopenaeus vannamei.

The current study aimed to provide a precise assessment of the genetic parameters associated with growth and white spot syndrome virus (WSSV) resistance traits in Pacific white shrimp (Litopenaeus vannamei). This was achieved through a controlled WSSV challenge assay and the analysis of phenotypic values of five traits: body weight (BW), overall length (OL), body length (BL), tail length (TL), and survival hour post-infection (HPI). The analysis included test data from a total of 1017 individuals belonging to 20 families, of which 293 individuals underwent whole-genome resequencing, resulting in 18,137,179 high-quality SNP loci being obtained. Three methods, including pedigree-based best linear unbiased prediction (pBLUP), genomic best linear unbiased prediction (GBLUP), and single-step genomic BLUP (ssGBLUP) were utilized. Compared to the pBLUP model, the heritability of growth-related traits obtained from GBLUP and ssGBLUP was lower, whereas the heritability of WSSV resistance was higher. Both the GBLUP and ssGBLUP models significantly enhanced prediction accuracy. Specifically, the GBLUP model improved the prediction accuracy of BW, OL, BL, TL, and HPI by 4.77%, 21.93%, 19.73%, 19.34%, and 63.44%, respectively. Similarly, the ssGBLUP model improved prediction accuracy by 10.07%, 25.44%, 25.72%, 19.34%, and 122.58%, respectively. The WSSV resistance trait demonstrated the most substantial enhancement using both genomic prediction models, followed by body size traits (e.g., OL, BL, and TL), with BW showing the least improvement. Furthermore, the choice of models minimally impacted the assessment of genetic and phenotypic correlations. Genetic correlations among growth traits ranged from 0.767 to 0.999 across models, indicating high levels of positive correlations. Genetic correlations between growth and WSSV resistance traits ranged from (-0.198) to (-0.019), indicating low levels of negative correlations. This study assured significant advantages of the GBLUP and ssGBLUP models over the pBLUP model in the genetic parameter estimation of growth and WSSV resistance in L. vannamei, providing a foundation for further breeding programs.

Peripheral blood transcriptomic profiling of molecular mechanisms commonly regulated by binge drinking and placebo effects.

Molecular responses to alcohol consumption are dynamic, context-dependent, and arise from a complex interplay of biological and external factors. While many have studied genetic risk associated with drinking patterns, comprehensive studies identifying dynamic responses to pharmacologic and psychological/placebo effects underlying binge drinking are lacking. We investigated transcriptome-wide response to binge, medium, and placebo alcohol consumption by 17 healthy heavy social drinkers enrolled in a controlled, in-house, longitudinal study of up to 12 days. Using RNA-seq, we identified 251 and 13 differentially expressed genes (DEGs) in response to binge drinking and placebo, respectively. Eleven protein-coding DEGs had very large effect sizes in response to binge drinking (Cohen's d > 1). Furthermore, binge dose significantly impacted the Cytokine-cytokine receptor interaction pathway (KEGG: hsa04060) across all experimental sequences. Placebo also impacted hsa04060, but only when administered following regular alcohol drinking sessions. Similarly, medium-dose and placebo commonly impacted KEGG pathways of Systemic lupus erythematosus, Neutrophil extracellular trap formation, and Alcoholism based on the sequence of drinking sessions. These findings together indicate the "dose-extending effects" of placebo at a molecular level. Furthermore, besides supporting alcohol dose-specific molecular changes, results suggest that the placebo effects may induce molecular responses within the same pathways regulated by alcohol.

Microfluidic Controllable Preparation of Iodine-131-Labeled Microspheres for Radioembolization Therapy of Liver Tumors.

Transcatheter arterial radioembolization (TARE) is of great significance for the treatment of advanced hepatocellular carcinoma (HCC). However, the existing radioembolic microspheres still have problems such as non-degradability, non-uniform size, and inability to directly monitor in vivo, which hinders the development of TARE. In this paper, a novel radioembolic agent, 131 I-labeled methacrylated gelatin microspheres (131 I-GMs), is prepared for the treatment of HCC. Water-in-oil (W/O) emulsion templates are prepared by a simple one-step microfluidic method to obtain methacrylated gelatin microspheres (GMs) after UV irradiation. A series of GMs with uniform and controllable size is obtained by adjusting the flow rate of each fluid. Both air-dried and freeze-dried GMs can quickly restore their original shape and size, and still have good monodispersity, elasticity, and biocompatibility. The radiolabeling experiments show that 131 I can efficiently bind to GMs by chloramine-T method, and the obtained 131 I-GMs have good radioactive stability in vitro. The results of in vivo TARE treatment in rats show that 131 I-GMs can be well retained in the hepatic artery and have a good inhibitory effect on the progression of liver cancer, showing the potential for the treatment of HCC.

[Latest Findings on Polyketides/Non-ribosomal Peptides That Are Secondary Metabolites of Streptococcus mutans].

Dental caries is a chronic infectious disease that occurs in the hard tissue of teeth under the influence of multiple factors, among which bacteria being a key factor. Streptococcus mutans ( S. mutans) is considered a major pathogen that causes caries. Secondary metabolites, including bacteriocins and polyketides/non-ribosomal peptides, are a class of small-molecule compounds synthesized by S. mutans. To date, polyketides/non-ribosomal peptides identified in S. mutans include mutanobactin, mutanocyclin, and mutanofactin, which are synthesized by the mub, muc, and muf biosynthetic gene clusters, respectively. These polyketides/non-ribosomal peptides play important roles in bacterial inter-species competition, oxidative stress, and biofilm formation. In this review, we provided an overview of the synthesis, function and regulation of three polyketides/non-ribosomal peptides of S. mutans, including mutanobactin, mutanocyclin, and mutanofactin, aiming to provide new insights into the cariogenic mechanism of S. mutans and to promote the better management of dental caries.

Peripheral blood transcriptomic profiling indicates molecular mechanisms commonly regulated by binge-drinking and placebo-effects.

Molecular changes associated with alcohol consumption arise from complex interactions between pharmacological effects of alcohol, psychological/placebo context surrounding drinking, and other environmental and biological factors. The goal of this study was to tease apart molecular mechanisms regulated by pharmacological effects of alcohol - particularly at binge-drinking, from underlying placebo effects. Transcriptome-wide RNA-seq analyses were performed on peripheral blood samples collected from healthy heavy social drinkers (N=16) enrolled in a 12-day randomized, double-blind, cross-over human laboratory trial testing three alcohol doses: Placebo, moderate (0.05g/kg (men), 0.04g/kg (women)), and binge (1g/kg (men), 0.9g/kg (women)), administered in three 4-day experiments, separated by minimum of 7-day washout periods. Effects of beverage doses on the normalized gene expression counts were analyzed within each experiment compared to its own baseline using paired-t-tests. Differential expression of genes (DEGs) across experimental sequences in which each beverage dose was administered, as well as responsiveness to regular alcohol compared to placebo (i.e., pharmacological effects), were analyzed using generalized linear mixed-effects models. The 10% False discovery rate-adjusted DEGs varied across experimental sequences in response to all three beverage doses. We identified and validated 22 protein coding DEGs potentially responsive to pharmacological effects of binge and medium doses, of which 11 were selectively responsive to binge dose. Binge-dose significantly impacted the Cytokine-cytokine receptor interaction pathway (KEGG: hsa04060) across all experimental-sequences that it was administered in, and during dose-extending placebo. Medium dose and placebo impacted pathways hsa05322, hsa04613, and hsa05034, in the first two and last experimental sequences, respectively. In summary, our findings add novel, and confirm previously reported data supporting dose-dependent effects of alcohol on molecular mechanisms and suggest that the placebo effects may induce molecular responses within the same pathways regulated by alcohol. Innovative study designs are required to validate molecular correlates of placebo effects underlying drinking.

Composite dissolvable microneedle patch for therapy of oral mucosal diseases.

A composite microneedle patch (MN patch) is developed for oral transmucosal administration. To improve the oral transmucosal drug delivery efficiency, the composite MN patch is designed to consist of an array of 100 dissolvable microneedles (MNs) with drug-loaded tips and a backing layer. The MNs are composed of two parts, the hyaluronic acid (HA) tip part and the polyvinylpyrrolidone (PVP) base part. Due to the small size and sufficient mechanical strength, the HA-PVP MNs can painlessly penetrate the oral mucosa barrier and deliver drugs directly to the basal layer or submucosa. Betamethasone sodium phosphate (BSP), as the model drug, is concentrated in the HA tip parts to avoid the drug waste caused by mucosa elasticity. Considering the special moist environment and saliva flow in the mouth, a double-layer backing layer composed of a poly(vinyl alcohol) (PVA) adhesive layer and an ethyl cellulose (EC) waterproof layer is designed and constructed, which could reduce the saliva flow effects. The in vitro and in vivo results demonstrate that the MN patch could achieve rapid and efficient BSP release in oral mucosa due to the rapid dissolution of HA. The proposed MN patch provides a novel strategy for the therapy of oral mucosal diseases.

Novel Multifunctional Stimuli-Responsive Nanoparticles for Synergetic Chemo-Photothermal Therapy of Tumors.

In this study, a novel class of multifunctional responsive nanoparticles is designed and fabricated as drug nanocarriers for synergetic chemo-photothermal therapy of tumors. The proposed nanoparticles are composed of a thermo-/pH-responsive poly(N-isopropylacrylamide-co-acrylic acid) (PNA) nanogel core, a polydopamine (PDA) layer for photothermal conversion, and an outer folic acid (FA) layer as a targeting agent for the folate receptors on tumor cells. The fabricated nanoparticles show good biocompatibility and outstanding photothermal conversion efficiency. The proposed nanoparticles loaded with doxorubicin (DOX) drug molecules are stable under physiological conditions with low leakage of drugs, while rapidly release drugs in environments with low pH conditions and at high temperature. The experimental results show that the drug release process is mainly governed by Fickian diffusion. In vitro cell experimental results demonstrate that the PNA-DOX@PDA-FA nanoparticles can be phagocytized by 4T1 tumor cells and release drugs in tumor cell acidic environments, and confirm that the combined chemo and photothermal therapeutic efficacy of PNA-DOX@PDA-FA nanoparticles is higher than the photothermal therapeutic efficacy or the chemotherapeutic efficacy alone. The proposed multifunctional responsive nanoparticles in this study provide a novel class of drug nanocarriers as a promising tool for synergetic chemo-photothermal therapy of tumors.

Improving the Stability of High-Voltage Lithium Cobalt Oxide with a Multifunctional Electrolyte Additive: Interfacial Analyses.

In recent years, various attempts have been made to meet the increasing demand for high energy density of lithium-ion batteries (LIBs). The increase in voltage can improve the capacity and the voltage platform performance of the electrode materials. However, as the charging voltage increases, the stabilization of the interface between the cathode material and the electrolyte will decrease, causing side reactions on both sides during the charge-discharge cycling, which seriously affects the high-temperature storage and the cycle performance of LIBs. In this study, a sulfate additive, dihydro-1,3,2-dioxathiolo[1,3,2]dioxathiole 2,2,5,5-tetraoxide (DDDT), was used as an efficient multifunctional electrolyte additive for high-voltage lithium cobalt oxide (LiCoO2). Nanoscale protective layers were formed on the surfaces of both the cathode and the anode electrodes by the electrochemical redox reactions, which greatly decreased the side reactions and improved the voltage stability of the electrodes. By adding 2% (wt.%) DDDT into the electrolyte, LiCoO2 exhibited improved Li-storage performance at the relatively high temperature of 60 °C, controlled swelling behavior (less than 10% for 7 days), and excellent cycling performance (capacity retention rate of 76.4% at elevated temperature even after 150 cycles).

[Comparative study between electroacupuncture at Neima point and Neiguan (PC 6) and epidural nerve block for preemptive analgesia in patients undergoing thoracic surgery].

OBJECTIVE: To compare the clinical effect between electroacupuncture (EA) at Neima point and Neiguan (PC 6) and epidural nerve block for preemptive analgesia in patients undergoing thoracic surgery. METHODS: Sixty patients with elective radical esophagectomy were randomly divided into a group A, a group B and a control group, 20 cases in each group. The patients in the group A were treated with injection of 20 mL 0.375% ropivacaine at epidural space 30 min before anesthesia induction, followed by normal anesthesia during operation; the patients in the group B were treated with 30 min EA at bilateral Neima point and Neiguan (PC 6) before anesthesia induction, followed by normal anesthesia during operation; the patients in the control group were treated with general anesthesia alone. Patient-controlled intravenous analgesia was applied for all the patients. The mean arterial pressure (MAP) and heart rate (HR) were recorded at the following time points: before acupuncture/epidural puncture (T0), skin incision (T1), extubation (T2) and 2 h after operation (T3); the dosage of anesthetics and extubation time were recorded; the plasma levels of ß-endorphin (ß-EP), 5-hydroxytryptamine (5-HT) and prostaglandin E2 (PGE2) were measured at the following time points: T0, T3, 12 h after operation (T4), 24 h after operation (T5) and 48 h after operation (T6). Visual analogue scale (VAS) was used to evaluate the analgesic effect. RESULTS: The MAP at T1 and T2 in the group A was lower than that in group B and control group (P<0.05), and HR at T1 and T2 was lower than that in control group (P<0.05). The MAP and HR at T1 and T2 in the group B were lower than those in the control group (P<0.05). The dosage of remifentanil in the group A and group B was lower than that in the control group (P<0.05), and extubation time was earlier than that in the control group (P<0.05). The content of ß-EP at T4, T5 and T6 in the group B was higher than that in the group A and control group (P<0.05); the contents of 5-HT and PGE2 at T3, T4 and T5 in the group A and group B were lower than those in the control group (P<0.05). The VAS scores at T3, T4 and T5 in the group A and group were lower than those in the control group (P<0.05). CONCLUSION: The preemptive analgesia of EA at Neima point and Neiguan (PC 6) and epidural nerve block could both provide effective perioperative analgesia for thoracic surgery. The EA could better maintain intraoperative hemodynamics and has less physiological disturbance.

Visual detection of trace lead(II) using a forward osmosis-driven device loaded with ion-responsive nanogels.

A simple and portable thermometer-type device based on forward osmosis-driven liquid column rising is developed for visual detection of trace Pb2+. The device consists of a top indicator tube, a chamber loaded with Pb2+-responsive poly(N-isopropylacrylamide-co-benzo-18-crown-6-acrylamide) (PNB) smart nanogels and a bottom semipermeable membrane. Upon the recognition of Pb2+, PNB smart nanogels undergo a Pb2+-induced hydrophobic to hydrophilic transition, which simultaneously causes the increase of osmotic pressure inside the device. Driven by this osmotic pressure difference, more Pb2+ solution flows into the device, causing the rise of the liquid column in the indicator tube, which can be directly observed by naked eyes. The relationship between the change of liquid column height and the Pb2+ concentration is investigated for the quantitative detection of Pb2+. With the proposed forward osmosis-driven device, trace Pb2+ as low as 10-10 M in aqueous solutions can be detected. This method provides a novel and simple strategy for the visual detection of trace Pb2+.

Sevoflurane modulates the cancer stem cell-like properties and mitochondrial membrane potential of glioma via Ca2+-dependent CaMKII/JNK cascade.

AIMS: Gliomas are responsible for the majority of deaths from primary brain tumours. Sevoflurane showed inhibition effects on the tumor progression in vitro. However, whether sevoflurane could affect the stemness of glioma stem cells (GSCs) and the potential molecular mechanism have not been well elucidated. MAIN METHODS: Effects of sevoflurane on cell viability, proliferation and invasion ability of glioma cells as well as tumor growth in vivo were assessed. Sphere formation assay was performed to evaluate the effect of sevoflurane on the stemness of GSCs. Effects of sevoflurane on mitochondrial function was evaluated by intracellular/mitochondrial reactive oxygen species (ROS) level and mitochondrial membrane potential. Expression levels of proliferation-related proteins, stemness markers and proteins in CaMKII/JNK cascade were measured by Western blot. KEY FINDINGS: Sevoflurane inhibited the viability, proliferation and invasion ability of glioma cells (U87MG and U373MG). Western blot showed that sevoflurane decreased the expression levels of proliferation and invasion-related proteins. Sphere formation ability of GSCs, expression levels of stemness markers and mitochondrial function were significantly suppressed by sevoflurane. Moreover, sevoflurane treatment significantly increased the Ca2+ concentration and stimulated phosphorylation of CaMKII, JNK and IRS1. Ca2+ chelator BAPTA-AM combined with sevoflurane synergistically inhibited colony forming ability and the expression levels of proliferation-related proteins and stemness markers. In addition, the in vivo study further confirmed that sevoflurane inhibited tumor growth via Ca2+-dependent CaMKII/JNK cascade. SIGNIFICANCE: The present study demonstrated that sevoflurane inhibited glioma tumorigenesis and modulated the cancer stem cell-like properties and mitochondrial membrane potential via activation of Ca2+-dependent CaMKII/JNK cascade.

[Clinical trial of electroacupuncture at Neimadian-point for cancer pain].

OBJECTIVE: To observe the clinical efficacy and safety of electroacupuncture (EA) at Neimadian-point for cancer pain. METHODS: A total of 140 cancer patients with pain were randomly divided into EA and control groups, with 70 cases in each group. The patients of the EA group received EA at Neimadian-point plus analgesia pump (all prepared with normal saline). The patients of the control group were treated by Sufentanil patient-controlled intravenous analgesia plus sham EA (without stimulation). The treatment was conducted once daily for two days at 8 o'clock every morning. Respectively, in 1 h before treatment (T0), 1 h (T1), 8 h (T2), 24 h (T3) after treatment of the first day, 1 h (T4), 8 h (T5), 24 h (T6) after treatment of the second day, the visual analogue scale (VAS) score of pain, and the plasma levels of norepinephrine, 5-HT, leucine enkephalin, ß-endorphin and dynorphin A1-13 were tested. The security level (1-4 grade) was assessed during the treatment. RESULTS: Compared with their own pre-treatment, in T1 to T6, the VAS scores, and the contents of plasma norepinephrine and 5-HT obviously decreased in both groups （P<0.05）, and the contents of leucine enkephalin, ß-endorphin and dynorphin A1-13 all increased (P<0.05) in the EA group. The analgesia effects were significantly higher in the EA group than in the control group in T1, T2, T4 and T5 (P<0.05,P<0.01). The therapeutic effect of EA at Neimadian-point was significantly superior to that of the Sufentanil in down-regulating plasma norepinephrine and 5-HT levels, and in up-regulating leucine enkephalin, ß-endorphin and dynorphin A1-13 levels (P<0.05,P<0.01). CONCLUSION: EA at Neimadian-point can effectively relieve the pain of cancer patients and improve their quality of daily life.

Saliva in the diagnosis of diseases.

Saliva is secreted from the salivary glands and has multiple functions, including mouth cleaning and protection, antibacterial effects and digestion. With the rapid advancement in salivaomics, saliva is well recognized as a pool of biological markers. Saliva, as a non-invasive and safe source, could be a substitute for blood in the diagnosis and prognosis of diseases. This review summarizes the latest advancements in saliva-related studies and addresses the potential value of saliva in the early diagnosis of oral diseases, such as dental caries and periodontal disease, as well as cancer, diabetes and other systemic disorders. Saliva biomarkers range from changes in the biochemical indices of DNA, RNA and proteins to the diversification of microbiota structures. This study integrates data reported in the recent literature and discusses the clinical significance and prospects for the application of saliva in the early diagnosis of diseases, translational medicine and precision medicine.

Peritoneal dialysis for autosomal dominant polycystic kidney disease: a retrospective study.

To describe the long-term clinical outcomes of patients with autosomal dominant polycystic kidney disease (ADPKD) who are on peritoneal dialysis (PD) therapy. We performed a retrospective matched-cohort analysis comparing the clinical outcomes of 30 ADPKD patients with those of 30 non-diabetic patients who had bilateral small kidneys between July 1 2007 and July 31 2014. The patient groups were matched by age, gender, and time of PD initiation. There were no significant differences in the demographic or biochemical parameters, comorbid conditions, residual glomerular filtration rate, or Charlson comorbidity score at the beginning of PD. The median renal volume was 1315 ml for the ADPKD group and 213 ml for the control group. Patients with ADPKD had similar 3-year patient survival (90.6% versus 86.3%, P=0.807) and technique survival (89.2% versus 74.3%, P=0.506) compared with non-ADPKD patients. Also, there was no significant difference in the peritonitis-free survival between the ADPKD and control groups (P=0.22), and rates of peritonitis were similar (0.19 versus 0.21 episodes per patient-year, P=0.26). No differences were observed in the incidence of PD-related complications, such as hernia and dialysate leak. ADPKD is not a contraindication for PD, and a subgroup of ADPKD patients with relatively small kidney volume can be treated using PD.

Predictive and prognostic significance of circulating endothelial cells in advanced non-small cell lung cancer patients.

The aim of this study was to evaluate the predictive and prognostic values of circulating endothelial cells (CECs) in patients with advanced non-small cell lung cancer (NSCLC). A total of 102 newly diagnosed advanced NSCLC patients were enrolled in this study. The amount of CECs was enumerated by flow cytometry (CD45- CD31+ CD146+) at baseline. CEC counts of 56 patients were detected before and after two cycles of chemotherapy. We correlated the baseline and reduction of CECs after therapy with objective response rate (ORR), progression-free survival (PFS), and overall survival (OS). The CEC level was significantly higher in advanced NSCLC patients, ranging from 57 to 1300 cells/10(5) cells (mean ± SD = 299 ± 221 cells/10(5) cells), than in patients with benign lesions (205 ± 97 cells/10(5) cells) and healthy volunteers (117 ± 33 cells/10(5) cells). When the cutoff value of CEC counts was 210 cells/10(5) cells, there was no significant association between CEC counts and OR/PFS/OS of the enrolled patients. However, patients with CEC response after chemotherapy have more chances to achieve OR (P < 0.001), and such patients showed longer PFS (P = 0.048) and OS (P = 0.018) than those without CEC response. In the multivariate analysis, the independent prognostic roles of brain metastasis (HR 6.165, P = 0.001), and CEC response (HR 0.442, P = 0.044) were found. The CEC counts could be considered as diagnostic biomarker for advanced NSCLC patients. And the reduction of CECs after treatment might be more ideal than the baseline CEC counts as a predictive or prognostic factor in patients treated with chemotherapy or anti-angiogenic therapy.

[Observation on electroacupuncture at neimadian (extra) and neiguan (PC 6) for analgesia after thoracic surgery].

OBJECTIVE: To observe the effectiveness and safety of electroacupuncture (EA) at Neimadian (Extra) and Neiguan (PC 6) for analgesia after thoracic surgery. METHODS: One hundred and twenty cases of thoracic surgery were randomly divided into an electroacupuncture (EA) group (60 cases) and a medication group (60 cases). EA was applied at Neimadian (Extra) and Neiguan (PC 6) for postoperation analgesia in the EA group, while patient-controlled intravenous analgesia (PCIA) was applied in the medication group. The score of visual analogue scale (VAS), analgesia effect, safety and beta-endorphin level after the treatment in both groups were compared. RESULTS: Compared with those before the treatment, the VAS scores in every time point after surgery were decreased (all P < 0.05), which were lower in the EA group (P < 0.01). The excellent and good rates were 96.7% (58/60) and 75.0% (45/60) seperately, the analgesia effect in the EA group (2 h after operation) was superior to that in the medication group (P < 0.01). The safety degree in EA group was higher to that in the medication group (P < 0.01). Compared with that before the treatment, the beta-endorphin level in two groups after treatment was both increased, which was higher in the EA group (P < 0.01). CONCLUSION: Electroacupuncture at Neimadian (Extra) and Neiguan (PC 6) has better analgesia effect (2 h after operation) and safety than PICA on analgesia after thoracic surgery.

[Clinical trial of treating stress-induced hyperglycemia patients with sepsis by supplementing QI, nourishing yin, and promoting blood flow].

OBJECTIVE: To investigate the effects of the treatment of supplementing qi, nourishing yin, and promoting blood flow (SQNYPBF) on the serum levels of CRP, TNF-alpha, IL-1 and IL-6, as well as the expression of HLA-DR in the peripheral monocytes in septic patients suffering from stress-induced hyperglycemia. METHODS: In the prospective randomized controlled study, eighty-five stress-induced hyperglycemia patients with sepsis were randomly assigned to the experimental group (45 cases) and the control group (40 cases). On the basis of routine therapies, including anti-infection, nutrition support, and the glucose control with insulin pump, patients in the experimental group additionally received the treatment of SQNYPBF (They were intravenously dripped with Shenmai Injection and Sulfotanshinone Sodium Injection, once daily, for 7 successive days). The serum levels of CRP, TNF-alpha, IL-1, and IL-6 and the HLA-DR expression of the peripheral monocytes were detected using ELISA before treatment and on the 8th day of the treatment. The total dose and the duration of insulin used, the morbidity of hypoglycemia, the APACHE II scores, and the mortality within 28-day hospitalization were compared between the two groups. RESULTS: The total dose of insulin used, the duration of insulin used, the morbidity of hypoglycemia, the APACHE II score on the 8th day of treatment, and the mortality within 28-day hospitalization significantly decreased in the experimental group, when compared with the control group (P < 0.05, P < 0.01). There was no difference in the expression of HLA-DR, the serum levels of CRP, TNF-alpha, IL-1, or IL-6 before treatment between the two groups (P > 0.05). After treatment the serum levels of CRP, TNF-alpha, IL-1, and IL-6 significantly decreased (P < 0.05) and the expression of HLA-DR significantly increased in the two groups (P < 0.05). Better effects were shown in the experimental group (P < 0.05, P < 0.01). CONCLUSION: SQNYPBF combined intensive insulin therapy could better improve the sepsis patients' immunity, decrease the plasma glucose level and duration, increase their survival rate, and improve their prognosis.
