Comparative Analysis of Clinical Effects of Insulin Aspart Combined with Acarbose and Metformin in the Treatment of Diabetes Mellitus.

Objective: To investigate the clinical effect of Insulin aspart 30 combined with acarbose and metformin enteric-coated tablets in the treatment of diabetes mellitus. Methods: 90 diabetic patients admitted to our hospital from January 2019 to December 2021 were selected as the research subjects, and the patients were randomly divided into group A (n = 30, using insulin aspart 30 alone), group B (n = 30, using insulin aspart 30 combined with metformin enteric-coated tablets), and group C (n = 30, using insulin aspart 30 combined with acarbose). The blood glucose balance before meals and before going to bed was maintained in the three groups of patients, and the blood glucose fluctuations, time to target, hypoglycemia, insulin dosage, and daily consumption of the three groups were compared. Results: There was no significant difference in blood glucose and average blood glucose at each time point before treatment in the 3 groups of patients (P > 0.05); compared with the blood glucose and average blood glucose at each time point after reaching the target in the three groups, the blood glucose after dinner in group A was significantly higher than that in groups B and C; at 2 : 00, the blood glucose of group A was significantly higher than that of group B (P < 0.05); there was no significant difference in blood glucose and average blood glucose at other time points (P > 0.05). There was no significant difference in blood glucose standard deviation, LAGE, and PPGE at each point in the three groups before treatment (P > 0.05); the standard deviation of blood glucose, LAGE, and PPGE at each point of the three groups of patients after reaching the standard were compared with those in the same group before treatment, and the differences were statistically significant (P < 0.05); there were statistically significant differences in blood glucose standard deviation, LAGE, and PPGE among the 3 groups after reaching the standard (P < 0.05). Compared among the three groups, the standard deviation of blood glucose and LAGE level at each point after reaching the standard, the difference between group B, group C, and group A was statistically significant (P < 0.05); however, there was no significant difference between the patients in group B and group C (P > 0.05); the level of PPGE in group A was higher than that in group B, which was higher than group C, and between group C and group A, the difference was statistically significant (P < 0.05). The time of reaching the standard in 3 groups was statistically significant (P < 0.05); there was no significant difference in the time of reaching the standard between group B and group C (P > 0.05). There was no significant difference in the incidence of hypoglycemia among the 3 groups (P > 0.05); there were significant differences in the proportion of insulin twice a day among the three groups (P < 0.05); there were statistically significant differences in daily insulin dosage among the 3 groups after reaching the standard (P < 0.05). The daily consumption of the three groups of patients after reaching the standard was compared, the difference was statistically significant (P < 0.05), and there was no significant difference between group A and group B (P > 0.05). Conclusion: The effect of insulin aspart 30 alone in the treatment of diabetic patients is not good, it will lead to a large fluctuation of blood sugar in the patient's body, and the time required to reach the standard is relatively long; the use of insulin aspart 30 combined with metformin enteric-coated tablets or acarbose can effectively reduce the blood sugar fluctuation range of diabetic patients and reduce the number of insulin injections, and insulin aspart 30 combined with metformin en teric-coated tablets can also greatly reduce the daily insulin dosage and daily consumption cost of diabetic patients.

Effect of dietary pyrroloquinoline quinone disodium in sows on intestinal health of the offspring.

The objective of this study was to investigate the effects of dietary pyrroloquinoline quinone disodium (PQQ·Na2) supplementation in sows during gestation and lactation on intestinal health in offspring. A total of 40 cross-bred (landrace × large white crossed with Duroc boar) multiparity gestation sows with an average parity of 4.3 were used in this study. Forty sows were allotted to 2 dietary treatments after breeding. One group was the control sows, which were fed a corn-soybean meal control diet (Con treatment, n = 20), and the other group was the treatment sows fed a control diet with 20 mg kg-1 PQQ·Na2 after breeding and through gestation and lactation (PQQ treatment, n = 20). The activities of SOD and GSH-Px were significantly (P < 0.05) increased by PQQ·Na2 supplementation, and MDA activity was decreased (P < 0.05) in the plasma of piglets. CAT, SOD and GSH-Px activities were significantly (P < 0.05) increased, and MDA activity was decreased (P < 0.05) in the small intestine of piglets. The mRNA expression levels of SOD1, CAT and MGST1 in the jejunum were increased in newborn piglets (P < 0.05), and the mRNA expression levels of HO1, SOD1, CAT, SOD2, GPX4, GPX1 and GCLC in the jejunum were increased in weaned piglets (P < 0.05). The mRNA expression of ZO-1 was increased (P < 0.05) in the jejunum of newborn piglets, and the mRNA expression of Occludin and ZO-1 was increased (P < 0.05) in the jejunum of weaned piglets. The villous height of the duodenum and jejunum of weaned piglets was increased (P < 0.05) by dietary PQQ·Na2. In weaned piglets, Bacteroidetes and Firmicutes were the most prevalent phyla in both the Con and PQQ·Na2 treatment groups, and the most prevalent genera were Alloprevotella and Bacteroides. At the phylum level, the abundance of Firmicutes was significantly increased (P < 0.05), and the abundance of Proteobacteria was significantly decreased (P < 0.05). At the genus level, the abundance of Alloprevotella was significantly increased (P < 0.05), and the abundance of Actinobacillus and Escherichia was decreased (P < 0.05). In conclusion, dietary supplementation with PQQ·Na2 in sows during gestation and lactation had positive effects on intestinal health in offspring.

Pyrroloquinoline quinone inhibits the production of inflammatory cytokines via the SIRT1/NF-κB signal pathway in weaned piglet jejunum.

The small intestine is an important digestive organ and plays a vital role in the life of a pig. In this study, we explored the regulatory role and molecular mechanism of pyrroloquinoline quinone (PQQ) on intestinal health and to discussed the interaction between PQQ and vitamin C (VC). A total of 160 healthy piglets weaned at 21 d were randomly divided into four treatment groups according to 2 × 2 factoring. The results showed that dietary PQQ could significantly decrease the levels of plasma globulin, albumin/globulin (A/G), indirect bilirubin (IBIL), blood urea nitrogen (BUN), creatinine (CREA) (P < 0.05 for each), total bilirubin, (TBIL) (P < 0.01), diamine oxidase (DAO) (P < 0.01) and immunoglobulin G (IgG) (P < 0.0001) and increase the levels of immunoglobulin A (IgA) and immunoglobulin M (IgM) (P < 0.0001) in the plasma of weaned piglets. Similarly, dietary VC could significantly decrease the levels of plasma globulin, A/G, DAO (P < 0.05 for each) and IgG (P < 0.0001) and increase the levels of IgA and IgM (P < 0.0001) in the plasma of weaned piglets. In addition, dietary PQQ increased (P < 0.05) the mRNA levels of antioxidant genes (NQO1, UGT1A1, and EPHX1), thereby enhancing (oxidized) nicotinamide adenine dinucleotide (NAD+) concentration and sirtuin 1 (SIRT1) activity in tissues. However, the addition of 200 mg kg-1 VC to the diet containing PQQ reduced most of the effects of PQQ. We further show that PQQ reduced (P < 0.05) the expression of inflammation-related genes (IL-2, IL-6, TNF-α, and COX-2) via the SIRT1/NF-κB deacetylation signaling. In conclusion, our data reveals that PQQ exerts a certain protective effect on the intestines of piglets, but higher concentrations of VC react with PQQ, which inhibits the regulatory mechanism of PQQ.

Chemical structure, chain conformation and rheological properties of pectic polysaccharides from soy hulls.

We obtained a new acidic soy hull polysaccharide (SHP-1) with a molecular weight (Mw) of 4.81 × 105 g/mol through ammonium oxalate and microwave assisted extraction. SHP-1 was mainly composed of galacturonic acid, galactose, rhamnose and arabinose (molar ratio = 46.59%:17.95%:14.77%:13.97%) with small amounts of fucose, glucose, mannose and xylose. The chemical structure was presumed to be of pectin-I type, consisting of 2/3 HGA and 1/3 RG-I. Furthermore, the rheological information and the chain morphology of SHP-1 were different in five solvents. Surfactant, salt and alkali solutions enhanced the solubility and flexibility of the polysaccharide, but the polysaccharide showed decreased fluidity under acidic conditions. The addition of ions and alkali increased the consistency coefficient of the solution, but the effect was far less than that of the cross-linking morphology. The structural and morphological information of purified SHP should aid in further study of its structure-function relationships and applications.

Transcriptome analysis of the effect of pyrroloquinoline quinone disodium (PQQ·Na2) on reproductive performance in sows during gestation and lactation.

BACKGROUND: Pyrroloquinoline quinone (PQQ), which is a water soluble, thermo-stable triglyceride-quinone, is widely distributed in nature and characterized as a mammalian vitamin-like redox cofactor. The objective of this study was to investigate the effects of pyrroloquinoline quinone disodium (PQQ·Na2) on reproductive performance in sows. RESULTS: Dietary supplementation with PQQ·Na2 significantly increased the total number of piglets born, the number of piglets born alive and the born alive litter weight. It also increased the antioxidant status in the placenta, plasma and milk. The concentration of NO was significantly increased in the plasma and placenta. RNA-seq analysis showed that 462 unigenes were differentially expressed between the control (Con) treatment and PQQ treatment groups. Among these unigenes, 199 were upregulated, while 263 unigenes were downregulated. The assigned functions of the unigenes covered a broad range of GO categories. Reproduction (27, 7.03%) and the reproduction process (27, 7.03%) were assigned to the biological process category. By matching DEGs to the KEGG database, we identified 29 pathways. CONCLUSIONS: In conclusion, dietary supplementation with PQQ·Na2 in gestating and lactating sows had positive effects on their reproductive performance.

Effect of pyrroloquinoline quinone disodium in female rats during gestating and lactating on reproductive performance and the intestinal barrier functions in the progeny.

The objective of this study was to investigate the effects of dietary pyrroloquinoline quinone disodium (PQQ·Na2) supplementation on the reproductive performance and intestinal barrier functions of gestating and lactating female Sprague-Dawley (SD) rats and their offspring. Dietary supplementation with PQQ·Na2 increased the number of implanted embryos per litter during gestation and lactation at GD 20 and increased the number of viable fetuses per litter, and the weight of uterine horns with fetuses increased at 1 d of newborn. The mRNA expression levels of catalase (CAT), glutathione peroxidase (GPx2), superoxide dismutase (SOD1), solute carrier family 2 member 1 (Slc2a1) and solute carrier family 2 member 3 (Slc2a3) in the placenta were increased with dietary PQQ·Na2 supplementation. Dietary supplementation with PQQ·Na2 in gestating and lactating rats increased the CAT, SOD and GPx activities of the jejunal mucosa of weaned rats on PD 21. Dietary supplementation with PQQ·Na2 in female rats affected the expression of tight junction proteins (claudin, zonula occludens-1 (ZO-1) and occludin) in the jejunal mucosa of their offspring by increasing the expression of ZO-1 mRNA in the expression of ZO-1 and claudin mRNA in the jejunal mucosa of weaned rats on PD 21. In conclusion, dietary supplementation with PQQ·Na2 in gestating and lactating female rats had positive effects on their reproductive performance and on the intestinal barrier of weaned rats.

[Effect of acupuncture on early cerebral palsy infants with parafunctional sitting position: a multi-centre, randomized, control research].

OBJECTIVE: To study the clinical effect of development theory based acupuncture on early cerebral palsy (CP) infants with parafunctional sitting position. METHODS: Totally 120 early CP infants were randomly assigned to two groups equally, the treatment group and the control group. All received acupuncture combined with training rehabilitation. Patients in the treatment group adopted acupuncture based on infants development theory, while those in the control group were treated by head acupuncture. Sitting functional points in Gross motor function measure (GMFM) 88 were observed in different groups and infant patients of various types before and after treatment. Root mean square (RMS) signals of sitting correlated muscles (latissimus dorsi, erector spinae, rectus abdominis) were recorded by surface electromyography (sEMG). The effective rate was evaluated by Nimodipine method. RESULTS: Compared with before treatment, sitting functional points were significantly improved in the two groups (P<0.01). After treatment, it was higher in the treatment group than in the control group (P<0.01). The advance amplitude was higher in CP infants of the spastic type and the hypotonic type than other types (P<0.01). Along with sitting process, latissimus dorsi RMS signals were gradually tapered, erector spinae RMS signals were gradually enhanced, and rectus abdominis RMS signals were slightly weakened. Compared with the control group, latissimus dorsi RMS signals obviously decreased, and erector spinae RMS signals obviously increased in the treatment group after treatment (all P<0.01). The total effective rate was higher in the treatment group than in the control group (89.29% vs. 77.78%, P<0.05). CONCLUSION: Infants development theory based acupuncture could effectively elevate dorsi-extensor muscles force, improve sitting position of 8 months to 1 year old CP infants with parafunctional sitting position.

[Clinical trials of acupuncture intervention combined with sitting training for cerebral palsy children with parafunctional sitting position].

OBJECTIVE: To observe the clinical effect of electroacupuncture (EA) combined with sitting training for cerebral palsy (CP) children with parafunctional sitting position. METHODS: A total of 120 parafunctional sitting CP child patients were randomly and equally divided into sitting training (control) group and EA plus sitting training (EA) group. The sitting training included assistant-sitting, legs-crossing-sitting, sitting with one-leg extending, long-term sitting, balancing-sitting, chair-climbing, and pron and hand-supporting, twice daily. EA (4 Hz, a tolerable strength) was applied to Mingmen (GV 4), Jizhong (GV 6), Shenshu (BL 23), and Pishu (BL 20) for 30 min, once daily. Both sitting training and EA treatment were conducted 5 times a week and continuously for a month. Twenty-items of sitting functions (0 - 3 point scaling) of Gross Motor Function Measure (GMFM) were used to evaluate the infantile patients' motor function and Nimodipine-method was employed to assess the curative effect. RESULTS: The sitting function scores were significantly increased in both control and EA groups compared with pre-treatment in the same one group (P < 0.01), and were apparently higher in the EA group than in the control group (P < 0.05), suggesting a better therapeutic effect of EA plus sitting training. EA plus sitting training intervention was better for the spastic and hypotonic patterns of CP patients than the other patterns in the therapeutic effect (P < 0.01). Of the two 60 cases of CP children in the control and EA groups, 20 (33.33%) and 22 (36.67%) experienced marked improvement, 24 (40.00%) and 30 (50.00%) were effective, and 16 (26.67%) and 8 (13.33%) failed, with the effective rates being 73.33% and 86.67% respectively. CONCLUSION: Acupuncture intervention combined with sitting training is better than sitting training intervention alone in improving cerebral palsy children with parafunctional sitting position, especially for the spastic and hypotonic CP patients.

[Effects of mild warming moxibustion on acupoints Shenque (RN8) and Guanyuan (RN4) for prevention and treatment of recurrent respiratory tract infection in children with cerebral palsy].

OBJECTIVE: To investigate the clinical effect of mild warming moxibustion (MWM) on acupoints Shenque (RN8) and Guanyuan (RN4) for treatment of recurrent respiratory tract infection (RRTI) in children with cerebral palsy (CP). METHODS: Sixty-four CP patients with RRTI were randomly and equally assigned to two groups, all received conventional rehabilitation treatment, but in acute infection stage, MWM was applied on the treated group, and intravenous dripping of immunoglobulin was given to the control group, all for 3 months. The frequency of RRTI attacking (Fre), the mean cough alleviating time (T-CA) and rale disappearing time (T-RA) during infection, as well as the serum levels of immune globulins during the post-treatment 1-year follow-up period were observed. RESULTS: The effectiveness in the treated group was better than that in the control group, showing in aspects of Fre (2.38 +/- 0.64 times vs. 6.50 +/- 0.84 times), T-CA (3.92 +/- 1.32 days vs. 6.48 +/- 2.18 days) and T-RA (4.66 +/- 1.82 days vs. 7.64 +/- 1.44 days), significant difference was shown between groups (P < 0.01). The serum levels of IgG, IgM and IgA all raised in both two groups (P < 0.05), comparison of immunoglobulin levels between groups showed that they were lower immediately after treatment, but higher at the end of the 1-year follow-up in the treated group than those in the control group. CONCLUSION: MWM on acupoints Shengue and Guanyuan has a better and long-term clinical effect for treatment of RRTI in children with CP.

Effect of warming moxibustion on Shenque acupoint for the treatment of acute diarrhea in children with infantile cerebral palsy.

OBJECTIVE: To observe the effect of warming moxibustion on Shenque acupoint (RN8) for the treatment of acute diarrhea in children with infantile cerebral palsy (ICP). METHODS: Clinical observation was performed on 60 ICP children suffering from acute diarrhea, who were randomly assigned to two groups equally. The Mox group was treated with warming moxibustion on Shenque acupoint (RN8) and the control group treated with Smecta. The efficacy was evaluated by markedly effective rate and total effective rate after a 6-day treatment, diarrhea arresting time as well as stool examination normalization rate and rotavirus negative reversion rate after a 3-day treatment. RESULTS: The total effective rate in the two groups was insignificantly different (P>0.05), but the markedly effective rate was significantly higher in the Mox group than in the control group (P<0.01); a significant difference was also seen between groups in terms of diarrhea arresting time, stool examination normalization rate and rotavirus negative reversion rate (all P<0.05). CONCLUSION: Warming moxibustion on Shenque acupoint is an effective treatment for acute diarrhea in ICP children, with advantages of simple manipulation and rapid effect initiation.

Mango profilin: cloning, expression and cross-reactivity with birch pollen profilin Bet v 2.

Mango can cause severe anaphylactic reactions. Profilin has been assumed partly responsible for the cross-reactivity between mango fruit and other allergens but has not been finally clarified. In this study, two isoforms of mango fruits profilin were amplified by RT-PCR and 3'RACE from total RNA. Each mango profilin cDNA includes an open reading frame coding for 131 amino acids. The deduced amino acid sequence of the corresponding protein show high identity with other allergenic profilins. Expression of the recombinant mango profilin was carried out in Escherichia coli BL21(DE3) using vector PET28a and the purification of the recombinant protein was performed via affinity chromatography with Ni+ coupled to sepharose. IgE reactivity of recombinant mango profilin was investigated by immunoblot and 8 of 18 mango-allergic patients tested presented specific IgE-antibodies to recombinant mango profilin. IgE-inhibition and ELISA inhibition experiments were performed to analyze mango profilin cross-reactivity with profilins from birch pollen and high cross-reactivities have been found.

[Effects of resveratrol on isolated thoracic aorta rings of rats].

OBJECTIVE: To investigate the relaxative characteristics of resveratrol on thoracic aortic artery in the rat and its mechanism. METHOD: We perfused the isolated rings and observed the response of NA-induced artery contraction to resveratrol under the Ca2+-contained and Ca2+-free bath solutions. In the same way were the effect of reveratrol on the vascular smooth muscle observed by adding two different concentration of KCl (30 and 80 mmol x L(-1)), and the effect on the contraction of the vascular smooth muscle depending on the intracellular calcium and extracellular calcium were also observed by adding NA. We also observed the effect of resveratrol on the contraction of rings induced by NA in the presence of L-NNA and Glibenclamide. RESULT: Resveratrol relaxed rat aorta rings precontracted by NA in a dose-dependent manner. The relaxant effect of resveratrol on the rat rings of endothelium-denuded group was reduced compared with that of endothelium-intact group; the relaxant effect of resveratrol on rat rings was higher under the condition of Ca2+-free bath solution than that under the condition of Ca2+-contained bath solution. Resveratrol had a repressive effect on the aorta's contraction induced by intracellular calcium, but had no effect induced by extracellular calcium. Resveratrol relaxed the contractions induced by KCl 30 mmol x L(-1) as well as KCl 80 mmol x L(-1), but the contraction curve of KCl 80 mmol x L(-1) was shifted upward significantly. In the L-NNA group, the relaxant effect was attenuated by (26.0 +/- 4.6) %; but there was no change in the group of Glibenclamide ( P > 0.05). CONCLUSION: The results indicate that resveratrol relaxes vascular smooth muscle in an endothelium dependent manner. The mechanisms for this phenomenon seem to be related with promoting synthesis and release of NO, opening Ca2+ activated K+ channel (KCa channel) as well as the inhibition of Ca2+ influx and release of Ca2+ from intracellular stores.
