Relationship of Glucagon-like Peptide 1 and Peptide YY with Catch-up Growth in Children Born Small for Gestational Age

Objective: Children born small for gestational age (SGA) are at a greater risk of developing insulin resistance, type 2 diabetes, and cardiovascular disease in adulthood. Gastrointestinal peptides, some secreted by intestinal L cells, regulate glucose and lipid metabolism and act on the hypothalamus to regulate energy homeostasis. The aim of this study was to explore whether gastrointestinal peptides are involved in metabolic disorders in SGA, which remains unclear. Methods: The secretion of glucagon-like peptide 1 (GLP-1) and peptide YY (PYY) were investigated in prepubertal children born SGA, the differences between catch-up growth and persistent short stature were compared, and correlation with glucose and lipid metabolism was analyzed. GLP-1, PYY, insulin-like growth factor 1, glucose, insulin, and lipid concentrations were analyzed in prepubertal children aged 4-10 years, stratified into three groups: short-SGA (SGA-s), catch-up growth SGA, and normal growth appropriate for gestational age (AGA). Results: Fasting GLP-1 and PYY concentrations were significantly lower in the SGA group than in the AGA group (p<0.05), and the GLP-1 level in infants born SGA with catch-up growth was lower than that in the SGA-s group (p<0.05). In the SGA population, GLP-1 showed a weak negative correlation with catch-up growth (r=-0.326) and positive correlation with fasting insulin (r=0.331). Conclusion: Lower GLP-1 concentrations may be associated with abnormal glucose metabolism in prepubertal children born SGA with catch-up growth. This is indirect evidence that impaired intestinal L cell function may be involved in the development of metabolic complications in SGA children.

[The fenrou zhijian theory in The Inner Canon of Huangdi and the stratified treatment of painful bi syndrome of meridian tendons].

The fenrou zhijian is defined as potential gap between different layers in the three-dimensional network structure formed by the twelve meridian tendons. Various pathological changes of the meridian tendons lead to the adhesion and closure of fenrou zhijian, causing abnormal mechanical conduction of the meridian tendon system, which in turn leads to painful bi syndrome of meridian tendons. As such, restarting the fenrou zhijian is the key to acupuncture treatment for painful bi syndrome of meridian tendons. Under the guidance of musculoskeletal ultrasound, the level and the angle of needle insertion of acupuncture at fenrou zhijian could be accurately controlled, the efficacy of acupuncture is improved.

Clinical efficacy of electromagnetic field therapy combined with traditional Chinese pain-reducing paste in myofascial pain syndrome.

BACKGROUND: Pulsed electromagnetic field (PEMF) therapy is widely used to treat myofascial pain syndrome (MPS). Damp-clearing and pain-reducing paste (DPP) comprises medical herbs and has been a traditional method of reducing myofascial pain in China for a long time, and it is usually administered with heating. However, the synergistic effect of PEMF therapy on heating-DPP in patients with MPS is unclear. AIM: To investigate the synergistic effect of PEMF therapy plus heating-DPP in lumbar MPS. METHODS: This double-blind, randomized, placebo-controlled trial was conducted on 120 patients with lumbar MPS who were randomly divided into an experimental group (EG, n = 60) and a control group (CG, n = 60). Patients in both groups were treated with heating-DPP combined with PEMF therapy; however, the electromagnetic function of the therapeutic apparatus used in the CG was disabled. Each treatment lasted for 20 min and was applied five times a week for two weeks. The short-form McGill Pain Questionnaire was applied at five time points: pretest, end of the first and second weeks of treatment, and end of the first and fourth week after completing treatment. Visual analog scale (VAS), present pain intensity index (PPI), and pain rating index (PRI; total, affective pain, and sensory pain scores) scores were then analyzed. RESULTS: Compared with the CG, the VAS, PPI and PRI scores (total, affective pain and sensory pain scores) in the EG were significantly lower after treatment and during follow-up. CONCLUSION: PEMF therapy combined with heating-DPP showed better efficacy than heating-DPP alone in reducing the overall intensity of pain and sensory and affective pain.

[Interpretation of therapeutic effect of fan-ashi point based on tension transmission of skeletal muscle].

Given that the biomechanical theory cannot well explain the therapeutic effect of fan-ashi point (a special site that may relieve pain by pressing), the skeletal muscle tension is adopted and it is attempted to interpret the mechanism of the curative effect and the effect onset of fan-ashi point. It is viewed that the longitudinal tension conduction and transverse tension conduction pathways of skeletal muscle are the material basis of the effect onset of fan-ashi point. Hence, acupuncture at fan-ashi point may alter the longitudinal or transverse tension conduction of skeletal muscle to relieve muscle and tendon pain.

Clinical, biochemical, molecular and therapeutic characteristics of four new patients of mitochondrial 3-hydroxy-3-methylglutaryl-CoA synthase deficiency.

Thirty patients with mitochondrial 3-hydroxy-3-methylglutaryl-CoA synthase (HMGCS) deficiency, which is a rare autosomal recessive disorder caused by HMGCS2 gene mutation are known. Here, we present four new patients with this disease. The characteristics including several metabolites of patients were recorded. Next-generation targeted sequencing and multiple sequence alignment of PCR amplified products allowed for mutational analysis of HMGCS2. Minigene assay transcript analysis confirmed pathogenicity of a splice site mutation. All cases had recurrent episodes with infections while they had no symptoms during intermissions. Patient 1, a girl, showed recurrent severe metabolic acidosis after infections from 8 months old and presented with weakness, vomiting and lethargy but had normal blood glucose. After treatment, she revived completely. Patients 2, 3 and 4 were boys who showed episodes of hypoglycemia since 8, 27 and 10 months of age, respectively. Glucose infusion reversed the symptoms. All four patients had hepatomegaly and abdominal imaging showed fatty livers. Serum free fatty acid increased. Urinary dicarboxylic acids and urinary 4-hydroxy-6-methyl-2pyrone presented. Diagnosis was confirmed by HMGCS2 gene analysis and 7 mutations (p.R188H, p.F420S, p.R206C, IVS2 + 1G > T, p.E401*, p.A450Pfs*7 and p.Q427*) of this gene were found. Here we report on the characteristics and genetics of four new patients with HMGCS deficiency. This study will enrich our knowledge of this rare autosomal recessive disorder.

Evidence of efficacy of acupuncture in the management of low back pain: a systematic review and meta-analysis of randomised placebo- or sham-controlled trials.

OBJECTIVES: To assess the evidence for the efficacy of acupuncture for non-specific low back pain (NSLBP), compared with sham or placebo therapies. METHODS: We searched Cochrane CENTRAL to December 2016, and conducted searches from 1980 to December 2016 in PubMed, MEDLINE and Embase. There were no regional restrictions applied. We included only randomised controlled trials of adults with NSLBP. Placebo/sham procedures were required of the control interventions. The trials were combined using meta-analysis when the data reported allowed for statistical pooling. RESULTS: 14 trials (2110 participants) were included in the review, and 9 were included in the meta-analysis. Immediately after the acupuncture treatment we found statistically significant differences in pain reduction between acupuncture and sham or placebo therapy (standardised mean difference (SMD) -0.40, 95% CI -0.54 to -0.25; I2 7%; 753 participants; 9 studies), but there were no differences in function (weighted mean difference (WMD) -1.05, 95% CI -3.61 to 1.52; I2 79%; 462 participants; 4 studies). At follow-up, there were significant differences in pain reduction (SMD -0.46, 95% CI -0.82 to -0.09; I2 67%), but not in function (WMD -0.98, 95%CI -3.36 to 1.40; I2 87%). We conducted subgroup analyses both immediately after treatment and at follow-up. CONCLUSION: There is moderate evidence of efficacy for acupuncture in terms of pain reduction immediately after treatment for NSLBP ((sub)acute and chronic) when compared to sham or placebo acupuncture.

[Correlation analysis between the surface electromyography and muscle fiber types of the core muscle group in the patients with myofascial pain syndromes].

OBJECTIVE: To detect the core muscle group in the patients with myofascial pain syndromes(MPS) by using the surface electromyography; to detect the distribution of muscle fiber type by the analysis of the median frequency and the slope of the median frequency. METHODS: From October 2017 to March 2018, there were 100 patients with the MPS, including 45 males and 55 females; the average age was 48.5 years old, ranging from 29 to 76 years old. There were 40 cases of left back pain and 60 cases of right back pain. The course of illness was more than 6 months. Another 40 healthy patients without pain in the waist were included in the control group, 20 males and 20 females; the average age was 47.3 years old, ranging from 29 to 76 years old. All the patients had different degrees of back pain and muscle stiffness, which were diagnosed as lumbar fasciitis by clinical and imaging examination. Surface electromyography was used to measure the characteristics of the lumbar core muscles (multifissions, iliocostal muscles, and longest muscle) of the three groups in the Biering-Sorensen testing, such as median frequency(MF) and absolute slope of median frequency (MFs). RESULTS: The MF values of the multifidus muscle in the three groups were as follows:the left side of the non-pain group was 133.88±26.61, and the right side was 131.39±29.81; left side of lift side pain group 117.29±10.93, right side 133.70±17.81; in the right pain group, the left side was 131.36±17.37, and the right side was 118.28±13.57. The MF values of the iliocostal muscle in the three groups were:106.94±28.01 on the left side of the non-pain group, 114.68±18.96 on the right side; left side of lift side pain group 93.95±11.17, right side 107.60±27.86; in the right pain group, the left side was 105.93±15.52, and the right side was 97.27±19.27. The MF values of the longest muscle in the three groups were:109.24±26.20 on the left side of the non-pain group, 112.58±17.70 on the right side. Left side of left side pain group 95.58±10.83, right side 108.79±26.39; in the right pain group, the left side was 106.50±17.98, and the right side was 98.20±11.16. The MFs values of the multifidus muscle in the three groups were:0.221±0.109 on the left side of the non-pain group, and 0.259±0.169 on the right side; left side of left side pain group 0.318±0.184, right side 0.210±0.159; in the right pain group, the left side was 0.258±0.169, and the right side was 0.386±0.166. The MFs values of the iliocostal muscles in the three groups were:0.241±0.158 for the left side of the non-pain group, and 0.238±0.128 for the right side. Left side of left side pain group 0.330±0.208, right side 0.252±0.171; in the right side pain group, left side 0.249±0.150, right side 0.343± 0.144. The MFs values of the longest muscle of the three groups were:0.244±0.252 on the left side of the non-pain group, and 0.210±0.128 on the right side; left side of left side pain group 0.348±0.255, right side 0.241±0.224; in the right pain group, the left side was 0.239±0.155, and the right side was 0.334±0.233. There were no statistically significant differences in MF and MFs values of the left and right lumbar multifidus muscle, iliocostal muscle and longest muscle in the non-pain group(P>0.05). MF values of the pain side multifidus muscle, iliocostal muscle and longest muscle in the lumbago group were lower than those in the non-pain group(P<0.05). MFs values of the painful side multifidus muscle, iliocostal muscle and longest muscle in the low back pain group were higher than those in the non-pain group(P<0.05). CONCLUSIONS: The muscle fatigue degree of the back muscle in the pain side of patients with MPs is decreased, and the muscle fiber type is dominated by II muscle fiber.

The diagnosis of cystinosis in patients reveals new CTNS gene mutations in the Chinese population.

Background Cystinosis is a rare autosomal-recessive disorder caused by a defective transport of cystine across the lysosomal membrane. Previous studies have mapped cystinosis to the CTNS gene which is located on chromosome 17p13, and various CTNS mutations have been identified to correlate them with this disease. Methods We analyzed six patients from five unrelated families who were diagnosed with cystinosis in our hospital. We described the diagnostic procedures for all the patients and proposed alternative therapies for cystinosis patients instead of using cysteamine, an orphan drug which was commercially unavailable in China. Moreover, genetic analysis of all patients' samples was carried out to identify novel CTNS gene mutations. Results and conclusions The patients in this study were followed up from 1 to more than 10 years to monitor their growth and development, which indicated that the alternative therapies we used were helpful to ameliorate the complications of the cystinosis patients without cysteamine. Furthermore, by sequencing the patients' genome, we identified novel mutations in the CTNS gene including: c.477C > G (p.S159R), c.274C > T (p.Q92X) and c.680A > T (p.E227V); these mutations were only observed in cystinosis patients and had never been reported in any other populations, suggesting they might be specific to Chinese cystinosis patients.

Clinical and Molecular Spectrum of Glutamate Dehydrogenase Gene Defects in 26 Chinese Congenital Hyperinsulinemia Patients.

OBJECTIVE: To characterize the genotype and phenotype of Chinese patients with congenital hyperinsulinism (CHI) caused by activating mutations in GLUD1, the gene that encodes mitochondrial enzyme glutamate dehydrogenase (GDH). METHODS: The clinical data of glutamate dehydrogenase hyperinsulinism (GDH-HI) patients were reviewed, and gene mutations were confirmed by whole exome sequencing (WES) and Sanger DNA sequencing. RESULTS: Twenty-six patients with GDH-HI heterozygous missense mutations were identified from 240 patients diagnosed as congenital hyperinsulinism over past 15 years. The median age at onset was 8 months (range: 1 day of life to 3 years). Seizure disorder was common in our cohort of patients (23/26). Four patients had normal serum ammonia levels; the median serum concentration was 101 µmol/L (range: 37-190 µmol/L). Hypoglycemic symptoms could be triggered by fasting or protein meals in all patients while blood glucose could be well controlled in all patients with diazoxide. Dosage of diazoxide could be reduced by protein restriction. Attempts to lower ammonia levels failed with different therapies such as protein restriction, benzoate, or N-carbamoyl glutamate. In follow-up, 15 of 26 patients had normal intelligence. Eleven patients developed epilepsy at the age of 6 months to 11 years. De novo mutations in GLUD1 were found in 24 cases, and dominant inheritance was observed in the other two; all were heterozygous. A total of 35% (9/26) patients carried c.1493C>T (p.S445L) mutation. CONCLUSIONS: Phenotypic heterogeneity of GDH-HI patients was observed within the Chinese cohort in the present study. The fact that most patients had a GLUD1 p. S445L mutation implies that this site could be a hotspot in Chinese patients. A high frequency of GDH-HI with normal ammonia has been reported in this study. Hence, GLUD1 mutational analysis may be an important method to differential diagnosis of GDH-HI from other diazoxide-responsive CHI in Chinese patients.

Effects of electroacupuncture stimulation at different spinal segmental levels in a rat model of diabetes mellitus.

BACKGROUND: Diabetes mellitus (DM) is associated with high morbidity, mortality and economic cost. Studies have shown that acupuncture can improve many symptoms of DM. OBJECTIVES: To examine for differences in effects of electroacupuncture (EA) stimulation at Weiwanxiashu, BL15 and BL23 in the streptozotocin (STZ)-induced DM rat model, to help guide clinical selection of acupuncture points. METHODS: 90 male rats weighing 160±5 g were used. 12 rats were control fed (Normal group) and 78 were fed a high-fat high-sugar diet for 8 weeks and underwent intraperitoneal STZ injection to model DM. 60 animals that met modelling criteria were randomly divided into an untreated DM group and four groups receiving EA at Weiwanxiashu (DM+WWX group), BL15 (DM+BL15 group), BL23 (DM+BL23 group) or a non-traditional acupuncture point on the tail (DM+Tail group). Fasting blood glucose, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and insulin levels were determined and an oral glucose tolerance test (OGTT) performed. RESULTS: EA at Weiwanxiashu had a glucose-lowering effect on the 21st and 28th days, decreased TC, TG and LDL-C levels, increase insulin levels and improved glucose tolerance. EA at BL15 had a glucose-lowering effect on the7th, 14th and 21st days of intervention but did not impact lipids, insulin or OGTT parameters. EA at BL23 or on the tail had no significant effects. CONCLUSION: EA at Weiwanxiashu and BL15 had differential effects on metabolic markers in the STZ-induced rat model of DM. These effects may be explained neuroanatomically by variations in the segmental innervation of the tissues at these locations.

Acupuncture for Primary Dysmenorrhea: A Meta-analysis of Randomized Controlled Trials.

Context • Primary dysmenorrhea (PD) is one of the most common complaints among young women. Acupuncture has been widely applied as a therapeutic modality in China and abroad for PD; however, the evidence for its benefits is still not convincing. Objective • The study intended to conduct a systematic review of randomized, controlled trials (RCTs) to evaluate the evidence regarding the use of acupuncture in treating PD. Design • The research team retrieved reports for RCTs published in 7 databases from their inception to March 2016, with no language restrictions: PubMed, Medline, Embase, the Cochrane Central Register of Controlled Trials, the Chinese National Knowledge Infrastructure database, the Chinese Biomedical database, and the Wanfang database. Setting • The study was conducted at the Beijing University of Traditional Chinese Medicine (Beijing, China). Participants • Participants in the reviewed studies were women aged 14 to 49 y who had received a diagnosis of PD in the absence of any visible pelvic pathology. Interventions • The types of acupuncture included traditional acupuncture, electroacupuncture, ear acupuncture, scalp acupuncture, superficial acupuncture, electrosuperficial acupuncture, wrist-ankle acupuncture, and abdominal acupuncture. Outcome Measures • The primary outcome was pain relief measured using a visual analogue scale (VAS), a verbal rating scale (VRS), or a numerical rating scale (NRS). The secondary outcomes included (1) overall improvement as measured by the short-form McGill pain questionnaire or symptom scale based on the Clinical Study Guideline for New Developed Chinese Medicine, (2) menstrual distress as measured by the Menstrual Distress Questionnaire, (3) quality of life as measured by a validated scale (eg, the short-form 36), and (4) adverse effects. Results • Twenty-three trials enrolling a total of 2770 patients were included in the review. Overall, most trials were of poor quality. Among the trials, only 6 were evaluated as having a low risk of bias, 3 of which indicated that acupuncture was statistically more effective than sham acupuncture-mean difference (MD), -3.51; 95% confidence interval (CI), -5.27 to -1.75; P < .0001; I², 0%-or no treatment-MD, -21.95; 95% CI, -25.45 to -18.45; P < .00001; I², 0%-on the VAS (0 to 100 mm). Acupuncture also showed superiority to the control arms on the VRS, the NRS, and the McGill pain questionnaire, but those findings had been influenced by methodological flaws. Conclusions • The available evidence suggests that acupuncture may be effective for PD and justifies future high-quality studies.

[Effect of Electroacupuncture at "Weiwanxiashu" (EX-B 3) on Islet Morphology and the Expression of Pancreatic Glucagon-like Peptide-1 Receptor in Type 2 Diabetes Rats].

OBJECTIVE: To observe the effect of electroacupuncture (EA) on pancreatic glucagon-like peptide-1 receptor (GLP-1 R), pancreatic and duodenal homeobox 1 (PDX-1) protein expression and blood glucose in type 2 diabetes rats, so as to explore the underlying mechanism of EA treatment in improving type 2 diabetes. METHODS: Sprague-Dawley rats were randomly divided into blank control group, model group, "Weiwanxiashu" (EX-B 3) group, "Xinshu" (BL 15) group, and "Shenshu" (BL 23) group, 12 rats in each group. Diabetes model was established by feeding the rat with high fat and high sugar diet combined with intraperitoneal injection of streptozotocin (35 mg/kg). All the EA groups received 2 Hz, 2 mA continuous wave treatment for 20 min everyday, 6 times per week lasting for 4 weeks. Fasting blood glucose was measured by Roche glucometer before and after treatment. Hematoxylin and eosin (HE) staining and Masson staining were used to detect pancreas morphology. GLP-1 R and PDX-1 protein expressions in the pancreas were detected by Western blot. RESULTS: Compared to the blank control group, fasting blood glucose was significantly increased in the model group(P<0.01), accompanied with shrunken islet area, reduced nucleus counts of islet ß cells, and compensatorily enlarged ß cell nucleus. Compared to the model group, EA intervention significantly reduced fasting blood glucose level only in the EX-B 3 group (P<0.05), partly restored pancreas morphology and nucleus counts of islet ß cells in the EX-B 3, BL 15, and BL 23 groups. Compared to the blank control group, GLP-1 R and PDX-1 expressions were decreased in the model group (P<0.01), while EA treatment could obviously increase GLP-1 R expression in the EX-B 3(P<0.01), BL 15 (P<0.01) and BL 23 (P<0.05) groups compared with the model group. The expression of GLP-1 R in the BL 15 group was the highest among the three EA groups (P<0.05,P<0.01), and that in the EX-B 3 group was higher than in the BL 23 group (P<0.05).There were no signifincant differences in the expression of PDX-1 protein among the three EA groups (P>0.05). CONCLUSIONS: EA treatment at EX-B 3 can reduce blood glucose via regulating pancreas function, increasing pancreatic GLP-1 R expression, and partly restoring the morphology of pancreas.

PI3K-GLUT4 Signal Pathway Associated with Effects of EX-B3 Electroacupuncture on Hyperglycemia and Insulin Resistance of T2DM Rats.

Objectives. To explore electroacupuncture's (EA's) effects on fasting blood glucose (FBG) and insulin resistance of type 2 diabetic mellitus (T2DM) model rats and give a possible explanation for the effects. Method. It takes high fat diet and intraperitoneal injection of streptozotocin (STZ, 30 mg/kg) for model preparation. Model rats were randomly divided into T2DM Model group, EA weiwanxiashu (EX-B3) group, and sham EA group (n = 12/group). EA (2 Hz continuous wave, 2 mA, 20 min/day, 6 days/week, 4 weeks) was applied as intervention. FBG, area under curve (AUC) of oral glucose tolerance test (OGTT), insulin resistance index (HOMA-IR), pancreatic B cell function index (HOMA-B), skeletal muscle phosphorylated phosphatidylinositol-3-kinase (PI3K), glucose transporter 4 (GLUT4), and membrane GLUT4 protein expression were measured. Results. EA weiwanxiashu (EX-B3) can greatly upregulate model rat's significantly reduced skeletal muscle PI3K (Y607) and membrane GLUT4 protein expression (P < 0.01), effectively reducing model rats' FBG and AUC of OGTT (P < 0.01). The effects are far superior to sham EA group. Conclusion. EA weiwanxiashu (EX-B3) can upregulate skeletal muscle phosphorylated PI3K protein expression, to stimulate membrane translocation of GLUT4 and thereby increase skeletal muscle glucose intake to treat T2DM.

Efficacy and safety of domestic leuprorelin in girls with idiopathic central precocious puberty: a multicenter, randomized, parallel, controlled trial.

BACKGROUND: In central precocious puberty (CPP), the pulse secretion and release of gonadotropin-releasing hormone (GnRH) are increased due to early activation of the hypothalamic-pituitary-gonadal axis, resulting in developmental abnormalities with gonadal development and appearance of secondary sexual characteristics. The CPP without organic disease is known as idiopathic CPP (ICPP). The objective of the study was to evaluate the clinical efficacy and safety of domestic leuprorelin (GnRH analog) in girls with ICPP. METHODS: A total of 236 girls with ICPP diagnosed from April 2012 to January 2014 were selected and were randomized into two groups. One hundred fifty-seven girls in the test group were treated with domestic leuprorelin acetate, 79 girls in the control group were treated with imported leuprorelin acetate. They all were treated and observed for 6 months. After 6-month treatment, the percentage of children with peak luteinizing hormone (LH) ≤3.3 U/L, the percentage of children with peak LH/peak follicle stimulating hormone (FSH) ratio <0.6, the improvements of secondary sexual characteristics, gonadal development and sex hormone levels, the change of growth rate of bone age (BA) and growth velocity, and drug adverse effects between two groups were compared. RESULTS: After the treatment, the percentage of children with a suppressed LH response to GnRH, defined as a peak LH ≤3.3 U/L, at 6 months in test and control groups were 96.80% and 96.20%, respectively, and the percentage of children with peak LH/FSH ratio ≤0.6 at 6 months in test and control groups were 93.60% and 93.70%, respectively. The sizes of breast, uterus and ovary of children and the levels of estradiol (E 2 ) were significantly reduced, and the growth rate of BA was also reduced. All the differences between pre- and post-treatment in each group were statistically significant (P < 0. 05), but the differences of the parameters between two groups were not significant (P > 0.05). CONCLUSIONS: Domestic leuprorelin is effective and safe in the treatment of Chinese girls with ICPP. Its effectiveness and safety are comparable with imported leuprorelin.

Effectiveness of multiple daily injections or continuous subcutaneous insulin infusion for children with type 1 diabetes mellitus in clinical practice.

Aims. To determine whether multiple daily injections (MDIs) or continuous subcutaneous insulin infusion (CSII) contributes to better glucose control in children with different type 1 diabetes duration. Methods. Subjects were grouped according to early (≤1 year after disease onset; 1A) or late (1-3 years after onset; 2A) MDIs/CSII treatment initiation. Corresponding control groups (1B, 2B) received insulin injections twice daily. Results. HbA1c levels were consistently lower in group 1A than in group 1B (6 months (T2): 7.37% versus 8.21%; 12 months (T3): 7.61% versus 8.41%; 24/36 months (T4/T5): 7.61% versus 8.72%; all P < 0.05), but were lower in group 2A than in group 2B only at T2 (8.36% versus 9.19%; P = 0.04). Levels were lower in group 1A than in group 2A when disease duration was matched (7.61% versus 8.49%; P < 0.05). Logistic regression revealed no correlation between HbA1c level and MDIs/CSII therapy. HbA1c levels were only negatively related to insulin dosage. Conclusions. Blood glucose control was better in patients receiving MDIs/CSII than in those receiving conventional treatment. Early MDIs/CSII initiation resulted in prolonged maintenance of low HbA1c levels compared with late initiation. MDIs/CSII therapy should be combined with comprehensive management.
