Abstract
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.

Abstract
Objective: To prepare the chitin/hyaluronic acid/collagen hydrogel loaded with mouse adipose-derived stem cells and to explore its effects on wound healing of full-thickness skin defects in rats. Methods: The research was an experimental research. Chitin nanofibers were prepared by acid hydrolysis and alkaline extraction method, and then mixed with hyaluronic acid and collagen to prepare chitin/hyaluronic acid/collagen hydrogels (hereinafter referred to as hydrogels). Besides, the hydrogels loaded with mouse adipose-derived stem cells were prepared. Thirty male 12-week-old guinea pigs were divided into negative control group, positive control group, and hydrogel group according to the random number table, with 10 guinea pigs in each group. Ethanol, 4-aminobenzoic acid ethyl ester, or the aforementioned prepared hydrogels without cells were topically applied on both sides of back of guinea pigs respectively for induced contact and stimulated contact, and skin edema and erythema formation were observed at 24 and 48 h after stimulated contact. Adipose-derived stem cells from mice were divided into normal control group cultured routinely and hydrogel group cultured with the aforementioned prepared hydrogels without cells. After 3 d of culture, protein expressions of platelet-derived growth factor-D (PDGF-D), insulin-like growth factor-Ⅰ (IGF-Ⅰ), and transforming growth factor β1 (TGF-β1) were detected by Western blotting (n=3). Eight male 8-week-old Sprague-Dawley rats were taken and a circular full-thickness skin defect wound was created on each side of the back. The wounds were divided into blank control group without any treatment and hydrogel group with the aforementioned prepared hydrogels loaded with adipose-derived stem cells applied. Wound healing was observed at 0 (immediately), 2, 4, 8, and 10 d after injury, and the wound healing rate was calculated at 2, 4, 8, and 10 d after injury. Wound tissue samples at 10 d after injury were collected, the new tissue formation was observed by hematoxylin-eosin staining; the concentrations of interleukin-1α (IL-1α), IL-6, IL-4, and IL-10 were detected by enzyme-linked immunosorbent assay method; the expressions of CD16 and CD206 positive cells were observed by immunohistochemical staining and the percentages of positive cells were calculated. The sample numbers in animal experiment were all 8. Results: At 24 h after stimulated contact, no skin edema was observed in the three groups of guinea pigs, and only mild skin erythema was observed in 7 guinea pigs in positive control group. At 48 h after stimulated contact, skin erythema was observed in 8 guinea pigs and skin edema was observed in 4 guinea pigs in positive control group, while no obvious skin erythema or edema was observed in guinea pigs in the other two groups. After 3 d of culture, the protein expression levels of PDGF-D, IGF-I, and TGF-β1 in adipose-derived stem cells in hydrogel group were significantly higher than those in normal control group (with t values of 12.91, 11.83, and 7.92, respectively, P<0.05). From 0 to 10 d after injury, the wound areas in both groups gradually decreased, and the wounds in hydrogel group were almost completely healed at 10 d after injury. At 4, 8, and 10 d after injury, the wound healing rates in hydrogel group were (38±4)%, (54±5)%, and (69±6)%, respectively, which were significantly higher than (21±6)%, (29±7)%, and (31±7)% in blank control group (with t values of 3.82, 3.97, and 4.05, respectively, Pvalues all <0.05). At 10 d after injury, compared with those in blank control group, the epidermis in wound in hydrogel group was more intact, and there were increases in hair follicles, blood vessels, and other skin appendages. At 10 d after injury, the concentrations of IL-1α and IL-6 in wound tissue in hydrogel group were significantly lower than those in blank control group (with tvalues of 8.21 and 7.99, respectively, P<0.05), while the concentrations of IL-4 and IL-10 were significantly higher than those in blank control group (with tvalues of 6.57 and 9.03, respectively, P<0.05). The percentage of CD16 positive cells in wound tissue in hydrogel group was significantly lower than that in blank control group (t=8.02, P<0.05), while the percentage of CD206 positive cells was significantly higher than that in blank control group (t=7.21, P<0.05). Conclusions: The hydrogel loaded with mouse adipose-derived stem cells is non-allergenic, can promote the secretion of growth factors in adipose-derived stem cells, promote the polarization of macrophages to M2 phenotype in wound tissue in rats with full-thickness skin defects, and alleviate inflammatory reaction, thereby promoting wound healing.

Abstract
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.

Abstract
Objective: To investigate the clinical characteristics of hereditary hypercholesterolemia in childhood. Methods: The clinical data including general conditions, clinical manifestations, laboratory tests, and genetic testing results of 4 children with hereditary hypercholesterolemia who admitted to Henan Children's Hospital from January 2020 to December 2020 were retrospectively analyzed. Results: There were 4 female children aged 5.5,1.5,6.3,3.1 years, all presented with skin xanthoxoma as the chief complaint. Plasma total cholesterol (range 11.8 to 20.9 mmol/L) and low density lipoprotein-cholesterol (range 8.2 to 13.7 mmol/L) were significantly elevated. The serum β-glutamate levels in case 1 (241.2 μmol/L) and case 2 (164.2 μmol/L) increased significantly. Genetic analysis revealed compound heterozygous variants of ABCG8 gene in case 1 and ABCG5 gene in case 2 who were diagnosed with sitosterolemia. Case 3 and 4 who all had family history of hypercholesterolemia and compound heterozygous variants of LDLR gene were diagnosed with familial hypercholesterolemia. After diet treatment, the blood lipids returned normal and the skin xanoma subsided in case 1 and 2. In case 3 and 4, the blood lipids gradually decreased after diet and rosuvastatin treatment. Conclusions: Xanthomatosis is the common clinical manifestation of sitosterolemia and familial hypercholesterolemia. Family history, blood plant sterol profile, genetic variation, and changes in blood lipids after early dietary treatment are helpful for disease identification.

Abstract
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.

Abstract
Objective: To analyse the efficacy of recombinant human growth hormone (rhGH) treatment in children born small for gestational age (SGA) with syndormic and non-syndormic short stature. Methods: The clinical data of 59 children born SGA who were diagnosed as short stature and admitted to the Center of Endocrinology, Genetics and Metabolism, Beijing Children's Hospital from July 2012 to June 2021 were collected and analyzed. According to the 2019 consensus on short stature, they were divided into syndromic group and non-syndromic group. Before treatment and 6, 12, 18 and 24 months after treatment, height standard deviation score (Ht-SDS), difference of height standard deviation (∆Ht-SDS) and homeostasis model assessment-insulin resistance index (HOMA-IR) were compared between groups, while Ht-SDS and HOMA-IR were compared before and after treatment. Independent t test or Kruskal-Wallis test were used for comparison between the 2 groups, and paired t test or Mann-Whitney U test were used for the intra-group comparison. Results: Among the 59 cases, 37 were males and 22 females, aged (5.5±2.3) years. There was no significant difference in Ht-SDS after 12 months of treatment between 2 groups (0.9±0.4 vs. 1.2±0.4, t=1.68, P=0.104) or in height SDS after 24 months of treatment (1.4±0.7 vs. 1.9±0.5, t=1.52, P=0.151). After 12 months of treatment, the insulin resistance index of the non-syndromic group was significantly higher than that of the syndromic group (2.29 (1.43, 2.99) vs. 0.90 (0.55, 1.40), Z=-2.95, P=0.003). There were significant differences in Ht-SDS between 6 months and before treatment, 12 months and 6 months in syndromic type (Z=7.65, 2.83 P<0.001, P=0.020), but all were significant differences in non-syndromic type between 6 months and before treatment, 12 months and 6 months, 18 months and 12 months, 24 months and 18 months (Z=11.95, 7.54, 4.26, 3.83, all P<0.001). Conclusion: The efficacy of rhGH treatment in children born SGA is comparable between syndromic and non-syndromic short stature cases, but non-syndromic children treated with rhGH need more frequent follow-up due to the risk of insulin resistance.

Abstract
OBJECTIVE This study aimed to analyze a comprehensive set of potential risk factors for obesity and overweight among Chinese children with a full range of ages and with wide geographical coverage. METHODS In the Prevalence and Risk Factors for Obesity and Diabetes in Youth (PRODY) study (2017-2019), the authors analyzed 193,997 children aged 3 to 18 years from 11 provinces, autonomous regions, and municipalities that are geographically representative of China. All participants underwent physical examinations, and their caregivers completed questionnaires including dietary, lifestyle, familial, and perinatal information of participants. A multilevel multinomial logistic regression model was used to evaluate the potential risk factors. RESULTS Among the actionable risk factors that were measured, higher consumption frequencies of animal offal (odds ratios [OR] for an additional time/day = 0.91, 95% CI: 0.88-0.95, same unit for OR below unless specified otherwise), dairy products (0.91, 95% CI: 0.88-0.94), freshwater products (0.94, 95% CI: 0.91-0.96), staple foods (0.94, 95% CI: 0.92-0.96), and coarse food grain (OR for every day vs. rarely = 0.92, 95% CI: 0.86-0.98) were associated with lower relative risk of obesity. However, higher restaurant-eating frequency (OR for >4 times/month vs. rarely = 1.21, 95% CI: 1.15-1.29) and longer screen-viewing duration (OR for >2 hours vs. <30 minutes = 1.16, 95% CI: 1.10-1.22) were associated with higher relative risk of obesity. Increased exercise frequency was associated with the lowest relative risk of obesity (OR for every day vs. rarely = 0.72, 95% CI: 0.68-0.77). CONCLUSIONS Changes in lifestyle and diet of Chinese children may help relieve their obesity burden.

Abstract
Objective: To evaluate the consistency of mass spectrometry (MS) and chemiluminescence immunoassay (CLIA) in detecting serum insulin-like growth factor-1 (IGF-1) and IGF-1 standard deviation score (SDS). Methods: This cross-sectional parallel control study prospectively collected the serum samples of 115 children with short stature disorders who were admitted in the Department of Endocrinology, Beijing Children's Hospital, Capital Medical University from February 2020 to December 2021. The serum IGF-1 level was detected by CLIA and MS, and converted to SDS for consistency analysis. Pearson analysis was used to analyze the correlation between the 2 methods, and Deming regression equation was established. Bland-Altman diagram and weighted Kappa coefficient were used to evaluate the consistency of the 2 methods. Results: There were 46 boys (40.0%) and 69 girls (60.0%), aged (8±3) years. Among the 115 cases, 37 were Turner syndrome, 59 were small for gestational age (SGA) at term, 1 was growth hormone deficiency (GHD) and 18 were other diseases. Pearson correlation analysis showed a preferable correlation between IGF-1 measured by the 2 detection methods (r=0.94, P<0.01), and IGF-1 SDS was also significantly correlated (r=0.92, P<0.01). Bland-Altman analysis showed that the consistency of serum IGF-1 levels detected by the 2 methods was poor, and the mean difference between CLIA and MS was 33.38 μg/L. The result detected by CLIA was significantly higher than that by MS, with SDS of 43.51 μg/L (95%CI -51.89-118.7 μg/L). After converting the results to SDS and removing 3 outliers (including 1 GHD patient), the weighted Kappa showed acceptable consistency (κ=0.68). Conclusion: In clinical application, after converting to IGF-1 SDS, IGF-1 detected by MS and CLIA can be used for cross-reference, but too high or too low levels should be cautious about.

Abstract
Objective: To compare the overnight variation trends in the duration of obstructive apnea events, and to explore the adaptive capacity to the pathophysiological consequences of periodic sleep disordered-breathing and its underlying mechanism in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: A retrospective analysis were performed of the polysomnographic (PSG) results of 89 snoring patients including 10 non-OSAHS, 15 mild, 29 moderate and 35 severe OSAHS. The total record time was divided into four equal phases, and the variation trends of the mean apnea duration (MAD) and the longest apnea duration (LAD) were compared with the progression of sleep phases in different groups. Correlation analysis was conducted with demographic indicators, pulse oxygen saturation (SpO2) and sleep related indicators. In addition, the number of apneas-time variability curve was plotted for fitting analysis. Results: In patients with severe OSAHS, both MAD [26.1(20.9, 31.4) s] and LAD [56.5(46.5, 82.0) s] were significantly higher than those of non-OSAHS, mild and moderate OSAHS (P<0.001). In addition, the MAD in the third and fourth quartiles were significantly higher than that in the first quartile [(28.4±9.0) s, (27.3±9.8) s, (22.3±9.9) s, respectively, P=0.046], and the LAD in the third quartile was significantly higher than that in the first quartile [56.5(38.5, 71.0) s, 41.0(28.0, 53.0) s, respectively, P=0.018]. In all subjects, the MAD and LAD in the third and fourth quartiles were significantly higher than those in the first quartile [MAD: 20.3(10.3, 29.2) s, 18.5(11.3, 24.2) s, 12.9(0.0, 21.8) s, respectively, P<0.001; LAD: 28.0(10.3, 50.5) s, 28.0(12.0, 44.5) s, 14.5(0.0, 32.3) s, respectively, P<0.001]. There was no statistical difference in the lowest SpO2 (LSpO2), the mean SpO2 (MSpO2), and the percent of sleep time oxygen saturation below 90% (T90%) of all subjects in different sleep phases (P>0.05). The LAD was positively correlated with obstructive apnea index (OAI, OR=1.660, P=0.025), but no correlation was observed with other indicators (P>0.05). The MAD increased 0.22 s per episode at the onset of sleep (1-31 apnea events), then dropped to 0.04 s of increase per episode, with a dynamics change of 5.5-fold slower. Conclusions: The MAD and LAD show a gradual prolongation trend with the progression of sleep phases, and the prolongation trend is the most obvious in patients with severe OSAHS, while the dynamic change trend of SpO2 is not obvious. There may be multiple adaptation mechanisms for recurrent hypoxic episodes, and the adaptation occurr in stages, with a rapid increase in MAD at the onset of sleep, follow by a markedly slower increase. Patients with severe OSAHS express the most complete pattern, suggesting the most severe pathophysiological outcomes.

Abstract
IMPORTANCE Obesity is a public health challenge in China, but the geographical profiles of overweight and obesity among Chinese children are limited. OBJECTIVE To examine regional disparities in the prevalence of obesity among the heterogeneous population of Chinese children and adolescents to provide a more accurate profile of obesity among children in China. DESIGN, SETTING, AND PARTICIPANTS The Prevalence and Risk Factors for Obesity and Diabetes in Youth (PRODY) study was a cross-sectional survey study conducted from January 1, 2017, to December 31, 2019, among 201 098 children aged 3 to 18 years from 11 provinces, autonomous regions, and municipalities that produced a sample of Chinese children with a full range of ages and wide geographical coverage using a multistage, stratified, cluster-sampling design. EXPOSURES Five regions geographically representative of China (northern, eastern, southern, western, and central). MAIN OUTCOMES AND MEASURES The body weights and heights of all participants were measured. Multilevel, multinomial logistic regression models were used to estimate the prevalence of overweight and obesity. RESULTS Among 201 098 healthy children (105 875 boys [52.6%]; mean [SD] age, 9.8 [3.8] years) from eastern, southern, northern, central, and western China, the highest obesity prevalence was estimated for children aged 8 to 13 years in northern China (from 18.8% [95% CI, 16.2%-21.7%] to 23.6% [95% CI, 20.5%-26.9%]) and for boys aged 3 to 6 years in western China (from 18.1% [95% CI, 10.4%-29.4%] to 28.6% [95% CI, 14.3%-49.0%]). Boys had a higher prevalence than girls of obesity only in eastern and northern China, with a mean difference in prevalence of 4.6% (95% CI, 3.8%-5.4%) and 7.6% (95% CI, 6.5%-8.6%), respectively. CONCLUSIONS AND RELEVANCE In this survey study, substantial geographic disparities in the prevalence of obesity and overweight were found among the heterogeneous population of Chinese children. The results suggest that special attention should be paid to vulnerable children and that regionally adapted interventions are needed to efficiently mitigate obesity in children.

Abstract
Objective: To investigate the clinical and genetic features, and treatment of X-linked hypophosphatemic rickets (XLH). Methods: In this retrospective study, we reviewed the medical records of 25 pediatric patients with XLH who were admitted to Department of Endocrinology Genetics and Metabolism,Beijing Children's Hospital from January 2010 to January 2020. The clinical characteristics, PHEX gene variants, as well as clinical outcome of the patients were summarized. To analyze the correlation between genotype and phenotype, the patients were divided into different subgroups according to the location of the variants, including N-terminal-located vs. C-terminal-located variant, and Zn-binding domain exon 17 or 19 variant vs. non-exon 17 or 19 variant. The age at onset, height standard deviation score (HtSDS), intercondylar or intermalleolar distance, fasting serum phosphorus, and HtSDS and intercondylar or intermalleolar distance at the final follow-up were compared by rank sum test or t text. Results: Among the 25 children with XLH, 8 were boys and 17 were girls. The median age of onset was 1.2 (1.0, 1.8) years, and the median age of diagnosis was 2.5 (1.5, 4.3) years. The main clinical manifestations were abnormal gait and lower limb deformity. The HtSDS was -2.0(-3.2, -0.8), and the intercondylar or intermalleolar distance was 4.5 (3.0, 6.0) cm. The fasting serum phosphorus level was 0.8 (0.7, 0.9) mmol/L, while the serum alkaline phosphatase level was (721±41) U/L and the serum calcium level was (2.5±0.1) mmol/L. Three patients (12%) had parathyroid hormone levels above the upper limit of the normal range. Twenty-five patients (100%) showed radiographic changes of active rickets. Nephrocalcinosis was found in 2 cases (9%). Twenty-four different PHEX variations were detected in 25 patients, among whom 11 (44%) had not been reported previously. No hot spot variation was found. No statistical differences (all P>0.05) were identified in clinical features and outcomes either in comparing patients with N-terminal (21 cases) and C-terminal (4 cases) variants, or in comparing patients with variant located in exon 17 or 19 (4 cases) or not (21 cases). Twenty-four cases (96%) were treated regularly with phosphate supplements and active vitamin D. After 2.7 (1.6, 5.0) years of follow-up, clinical symptoms were relieved in 96% (24/25) of the patients. The HtSDS after treatment had no significant difference compared to that before treatment (-2.0(-3.2, -0.8) vs.-2.0(-2.8, -1.1),Z =-0.156, P>0.05), while the intercondylar or intermalleolar distance after treatment was significantly reduced compared to that before treatment (4.5(3.0, 6.0) vs. 1.5(0, 3.3) cm, Z =-3.043, P<0.05). Bone X-rays were reexamined in 17 cases after treatment, and radiographic signs of rickets were improved. Eighteen cases had secondary hyperparathyroidism and 7 cases had nephrocalcinosis. Conclusions: The main clinical manifestations of XLH are abnormal gait, lower limb deformity and short stature. A high proportion of novel variations of PHEX gene but no hot spot variation neither genotype-phenotype correlation are found. Regular treatment with phosphate supplements and active vitamin D can significantly improve the symptoms except for the height. However, the rate of adverse events including secondary hyperparathyroidism and nephrocalcinosis seems to be high.

Abstract
Objective: To explore the clinical and genetic characteristics of Noonan syndrome in children. Methods: The clinical characteristics,genetic analysis and follow-up data of 20 children diagnosed with Noonan syndrome who were admitted to Department of Endocrinology, Genetics and Metabolism, Beijing Children's Hospital, Capital Medical University from March 2016 to December 2020 were retrospectively analyzed. Results: Among 20 children with Noonan syndrome, 13 were males and 7 were females. The age at diagnosis was 5.9 years (1.1 years to 12.2 years). The most common clinical complaints were delayed height growth, followed by hypospadias or cryptorchidism in 2 cases, and special facial appearance in 1 case. Physical examination revealed 12 cases of Noonan syndrome with facial features, 9 cases with cryptorchidism and hypospadias, 10 cases with abnormal cardiac structure, and 10 cases with mental retardation; Twelve patients were detected with PTPN11 variations, 4 patients carried SOS2 variations, 2 cases were confirmed with variations in SHOC2 and SOS1. Six children received recombinant human growth hormone treatment, and their height increased by 4.0 (2.5-6.0) cm to varying degrees at 9 months. No adverse events occurred. Conclusions: Male Noonan syndrome is more frequently found with external genitalia. In addition to the high frequency of PTPN11 variation, the frequency of gene variation in SOS2 gene is higher than previously reported. All of the SOS2 variations are de novo. The syndrome phenotype profiles could vary with the admitted clinical departments. To understand the full picture of the syndrome, it is necessary to collect medical information from different departments.

Abstract
Objective: To analyze the clinical, genetic characteristics and follow-up data of Chinese patients with hypophosphatasia (HPP). Methods: A retrospective analysis was conducted on six children with HPP admitted to the Department of Endocrinology, Genetics and Metabolism in Beijing Children's Hospital from October 2010 to January 2019. Summarized the clinical and follow-up data of all six patients, as well as the pathogenic variants of five children. Results: The serum alkaline phosphatase levels of all six children (five males and one female) were significantly reduced (2-49 U/L). The 6 patients aged from 2 months to 6 years and 4 months, 4 infantile HPP, 1 childhood HIP and 1 odonto HPP. The four patients with infantile HPP presented with anorexia, slow weight gain and hypercalcemia, whereas the one patient with childhood HPP and the other patient with odonto HPP had tooth loss. The patient with childhood HPP also manifested with motor dysfunction. Genetic testing was conducted for five patients and 4 unrelated Chinese families and revealed 10 variations in ALPL gene, including 7 missense variation, 1 insertion variation, 1 frameshift variation, 1 deletion variation.Of which 3 were novel (p.Y28C, p.268, F>L, p.A176V).One of the infantile patients lost follow-up and the other three deceased. The clinical conditions were much improved with medical intervention for patients with childhood, orodonto HPP. Conclusions: While HPP patients with different ages of onset present with common features, the prognosis differ significantly. The prognosis is good for patients with childhood, orodonto HPP and poor for patients with infantile HPP. Genetic testing is the main method for definitive diagnosis.

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.

Abstract
Objective: To analyze the clinical and genetic features, as well as the treatment outcomes of two boys with nephrogenic syndrome of inappropriate antidiuresis (NSIAD) caused by gain-of-function mutations in the V2 vasopressin receptor gene (AVPR2). Methods: The clinical manifestations, genetic testing, therapeutic interventions and the outcomes of two boys with NSIAD hospitalized in the Department of Endocrinology, Beijing Children's Hospital in April 2019 were reported. A literature search with "Nephrogenic syndrome of inappropriate antidiuresis" and "AVPR2 gene" as keywords was conducted at the China national knowledge infrastructure (CNKI), the Wanfang Data Knowledge Service Platform, PubMed and Springer Link up to May 2020. Relevant published articles were reviewed. Results: The two cases presented with chronic and severe hyponatremia with hypo-osmolality, inappropriately elevated urinary osmolality and urinary sodium levels. The onset age was 5.25-years and 2 months respectively. AVPR2 sequencing revealed a previously described hemizygous activating mutation (c.409C>T, p.R137C) in both of boys, each inherited the variant from their mother. Patient 1 limited fluid intake by himself in his daily life, intravenous and oral sodium supplementations showed no significant increase of serum sodium level. Oral furosemide increased the serum sodium level and maintained it within normal range. The serum sodium and potassium levels were in the normal range during the 1-year follow-up period with oral furosemide. The serum sodium level of Patient 2 increased with restricting fluid intake and with salt supplementation. However, after he experienced respiratory infection, the plasma sodium level decreased. Subsequently, oral anti-infection medicine and furosemide were applied. The serum sodium level increased two days later and remained at a normal range afterwards. The boy was 1 year old with normal growth. He stopped taking furosemide after 4 months while taking 1 gram of salt per day, the blood sodium level maintained at normal range. Literature search identified no reports in Chinese journals, whereas 50 publications were found in English journals. A total of 30 NSIAD probands were reported and 16 of those (53%) had childhood onset, most presented with seizures. The majority had a hotspot change at the nucleotide position of 409 in AVPR2. Nine cases had an amino acid change as R137C and five cases as R137L. Fluid restriction and oral urea intake were main treatment options, no report so far was found with oral furosemide treatment. Conclusions: NSIAD presented with hyponatremia without any other specific presentations. Genetic testing for variants in AVPR2 is helpful for early diagnosis and timely treatment. The first two cases of oral furosemide treatment were reported by the article which helped to maintain a normal serum sodium level after limiting fluid intake and supplementing sodium which showed limited effect.

Abstract
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.

Abstract
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.

Abstract
Trace amounts of selenium (Se) are essential for several organisms, and deficiencies therein have adverse effects on growth, development, and reproduction; this is particularly significant in animals raised for milk and livestock production. To study the effect of Se on Guanzhong dairy goats, their diets were supplemented with different sources (inorganic or organic) and Se concentrations (0.2 or 0.4 mg Se/kg). A non-Se-fortified basal diet served as a negative control, and a sixth treatment group received both inorganic and organic Se sources (0.2 mg Se/kg diet each). Dietary Se supplementation increased milk production, with organic Se being more effective than inorganic Se. Selenium supplementation also increased Se concentration and glutathione peroxidase activity in whole blood, with organic Se more effective than inorganic Se at the same Se concentration. With increasing Se in diets, the Se content in milk increased markedly, reaching a plateau value at day 30 in all groups, and organic Se (0.4 mg/kg diet) had the best effect. In addition, dietary Se sources and concentrations markedly affected Se concentrations in different tissues and organs. Thus, organic Se supplementation of a basal diet at 0.4 mg/kg is practically applicable for Se-enriched milk and meat production in Guanzhong dairy goats.

Abstract
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.

Abstract
BACKGROUND Methylation defects at chromosome 6q24 usually induce transient neonatal diabetes mellitus. There are few reports of permanent neonatal diabetes mellitus caused by abnormalities of 6q24. We report the first case of permanent neonatal diabetes mellitus to be associated with confirmed methylation defects at chromosome 6q24. CASE REPORT A baby girl, small for her gestational age, was found to have high blood glucose 1 day after birth, with no systematic congenital anomalies. She showed no remission of diabetes and has hitherto been reliant on insulin (now aged of 5.5 years), which supports a diagnosis of permanent neonatal diabetes mellitus. The single nucleotide polymorphism array and highly polymorphic short tandem repeat analysis identified paternal uniparental disomy of chromosome 6, and a genome-wide analysis ruled out mutations in coding and non-coding regions. CONCLUSION This report expands the varieties of neonatal diabetes known to be induced by methylation defects at chromosome 6q24, and suggests that the diagnostic evaluation of permanent neonatal diabetes mellitus should be expanded to include testing for 6q24.

Abstract
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.

Abstract
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.

Abstract
Dynamically reconfigurable and transparent signal spectral conversion is expected to play a vital role in seamlessly integrating traditional metropolitan optical networks and mobile fronthaul/backhaul networks. In this paper, a simple digital signal processing (DSP)-enabled spectral converter is proposed and extensively investigated, for the first time, which just utilizes a single standard dual-parallel Mach-Zehnder modulator (DP-MZM) driven by SDN-controllable RF signals and DC bias currents. As an important thrust of the paper, optimum operating conditions of the proposed converter are analytically identified, statistically examined and experimentally verified. Optimum operating condition-supported spectral converter performances in IMDD-based network nodes are explored both theoretically and experimentally in terms of frequency detuning range-dependent conversion efficiency, spectral conversion-induced OSNR/power penalty and transparency to input signal characteristics. The proposed spectral converter has unique advantages including low configuration complexity, strict transparency, SDN-controllable performance reconfigurability and flexibility, as well as negligible spectral conversion-induced latency.

Abstract
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 β cells, and compensatorily enlarged β 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 β 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.

Abstract
Decorin (DCN), a component of the extracellular matrix (ECM), participates in ECM assembly and influences cell proliferation and apoptosis in many mammalian tissues and cells. However, expression and function of DCN in the ovary remain unclear. This study cloned the full-length cDNA of goat DCN obtained from the ovary of an adult goat. Sequence analysis revealed that the putative DCN protein shared a highly conserved amino acid sequence with known mammalian homologs. The tissue distribution of DCN mRNA expression was evaluated by real-time PCR, and the results showed that DCN was widely expressed in the tissues of adult goat. Immunohistochemistry results suggested that DCN protein existed in the granulosa cells and oocytes from all types of follicles and theca cells of antral follicles. Moreover, hCG-induced DCN mRNA expression was significantly reduced by the inhibitors of protein kinase A, PI3K, or p38 kinase (P < 0.05), which are key mediators involved in hCG-induced DCN expression. Overexpression of DCN significantly increased apoptosis and blocked cell cycle progression in cultured granulosa cells (P < 0.05). Western blot analysis also showed that overexpression of DCN upregulated the expression levels of p21 protein (P < 0.05), whereas no effects were observed on the expression of Bax and Bcl-2 and on Bcl-2/Bax ratio (P > 0.05). These findings suggested that DCN regulates the apoptosis and cell cycle of granulosa cells.

Abstract
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 (E2) 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.

Abstract
Brain-derived neurotropic factor (BDNF) and its high-affinity receptor, tyrosine kinase receptor B, have been assumed to be involved in female reproduction and have recently shown to play an essential role in follicle activation and oocyte maturation. In this study, we analyzed the expression of miR-10b and BDNF in the ovary and discovered that the expression of miR-10b was higher in monotocous goat ovaries than in polytocous goat ovaries, whereas the expression pattern of BDNF in ovary was opposite. Moreover, human chorionic gonadotropin induced rapid and transient expression of BDNF messenger RNA and protein. In contrast, human chorionic gonadotropin upregulated miR-10b expression in a time-dependent manner. The BDNF gene was identified as a direct target of miR-10b using a dual-luciferase reporter assay. Transfection of granulosa cells with miR-10b decreased BDNF messenger RNA and protein levels. MiR-10b overexpression inhibited cell proliferation, whereas BDNF promoted cell proliferation. However, a combined treatment with miR-10b and BDNF promoted cell proliferation, indicating that the reintroduction of BDNF reversed the suppressive effect of miR-10b. These results demonstrate that miR-10b downregulates BDNF expression in granulosa cells by directly targeting the 3' untranslated regions and plays an important role in inhibiting granulosa cell proliferation by targeting BDNF.

Abstract
Tissue inhibitor of metalloproteinase 1 (TIMP1) belongs to a group of endogenous inhibitors that control the activity of matrix metalloproteinases and other metalloproteinases. TIMP1 is ubiquitously expressed and implicated in many physiological and pathologic processes. In this study, the full-length complementary DNA of goat (Capra hircus) Timp1 was cloned from adult goat ovary for the first time to better understand the regulatory role of TIMP1. The putative TIMP1 protein shared a high amino acid sequence identity with other species. Real-time polymerase chain reaction results showed that Timp1 was widely expressed in adult goat tissues, and messenger RNA expression was higher in the ovary than in other tissues; meanwhile, increasing expression of Timp1 was also discovered during the process of follicle growth and corpus luteum. We then investigated Timp1 expression patterns in different types of ovarian follicular cells from goats. In small or large antral follicles, Timp1 expression was higher (P < 0.05) in theca cells than in granulosa cells, cumulus cells, and oocytes. Increasing expression of Timp1 in theca and granulosa cells was observed as the variation of the follicle size. Immunohistochemical analyses further revealed the presence of the TIMP1 proteins in follicles at all antral stages of development. The most intense staining for TIMP1 was observed in the theca cells and granulosa cells of large antral follicles and corpus luteum. Timp1 was highly (P < 0.05) induced in granulosa cells in vitro after treatment with the luteinizing hormone agonist, human chorionic gonadotropin. Treatments with forskolin, phorbol 12-myristate 13-acetate, or phorbol 12-myristate 13-acetate + forskolin could also stimulate Timp1 messenger RNA expression. The effects of human chorionic gonadotropin were reduced (P < 0.05) by the inhibitors of protein kinase A, protein kinase C, MAPK kinase, or p38 kinase, indicating that Timp1 expression could be adjusted by luteinizing hormone-initiated activation of these signaling mediators. Our results suggested that TIMP1 may be involved in regulating ovarian follicle development and ovulation.

Abstract
In this study, Xinong Saanen (SN) and Guanzhong (GZ) dairy goat breeds were used to detect single nucleotide polymorphisms (SNPs) in the 5'-flanking region of the KITLG gene by DNA sequencing and primer-introduced restriction analysis-polymerase chain reaction. Two novel SNPs (g.13090G>T and g.13664C>A) were identified (GenBank Accession no. KM658964). Furthermore, g.13090G>T and g.13664C>A loci were closely linked in SN and GZ breeds (r(2) > 0.33). Association analysis results showed that g.13090G>T and g.13664C>A SNPs significantly affected litter size (P < 0.05). The litter size of individuals with the combined genotype GG/CC from both dairy goat breeds was greater than that of individuals with TT/AA in average parity (P < 0.05). Known biochemical and physiological functions, along with our results, indicated that GG/CC could be used in marker-assisted selection to choose individuals with greater litter size from both breeds. These results extend the spectrum of genetic variation in the caprine KITLG gene and may contribute to genetic resources and breeding of goats.

Abstract
Utilizing low-cost, 2.2GHz modulation bandwidth, uncooled and standalone directly modulated VCSEL (DM-VCSEL)-based real-time dual-band optical OFDM (OOFDM) transmitters, aggregated 16.375Gb/s transmissions of OOFDM signals having bandwidths approximately 3.8 times higher than the VCSEL manufacturer-specified modulation bandwidths, are experimentally demonstrated, for the first time, over 200m OM2 MMF links based on intensity modulation and direct detection. The aggregated signal transmission capacities of the aforementioned links vary by just 8% for various OM2 MMFs ranging from 100m to 500m, and by just 10% over a 1GHz passband carrier frequency detuning range. Such dual-band OOFDM adaptability-induced excellent performance robustness and large passband frequency tunability can significantly relax the requirements on VCSEL modulation bandwidth for achieving specific transmission performances for cost-sensitive application scenarios such as data centers.

Abstract
Xinong Saanen (SN) and Guanzhong (GZ) goat breeds were used to detect single nucleotide polymorphisms (SNPs) in the coding regions with their intron-exon boundaries and the proximal flanking regions of KITLG gene by DNA sequencing and genotyped by PCR-restriction fragment (PCR-RFLP). Four novel SNPs (g.12654G>A, g.12772G>A, g.12829T>C and g.23683C>T) were identified (GenBank accession No. KM609289). It was shown that Xinong Saanen and Guanzhong goat breeds were in Hardy-Weinberg disequilibrium at g.12654G>A, g.12772G>A and g.12829T>C loci (P<0.05). The g.12654G>A, g.12772G>A and g.12829T>C loci were closely linked in both goat breeds (r(2)>0.33). Results of an association analysis indicated that SNPs g.12654G>A, g.12772G>A and g.12829T>C had significant effects on litter size (P<0.05). The combined genotypes of four SNP loci also affected litter size with the C7(GG/GG/CC/CC) genotype in the SN goat breed and C1(AA/GG/CC/CC) and C7(GG/GG/CC/CC) genotypes in the GZ goat breed having the highest litter size. The biochemical and physiological functions, together with the results obtained in our investigation, suggest that C7(GG/GG/CC/CC) could be used in marker-assisted selection to select the individuals with higher litter size in both goat breeds. The results extend the spectrum of genetic variation of the caprine KITLG gene, which might contribute to goat genetic resources and breeding.

Abstract
Complementary DNA (cDNA) is valuable for investigating protein structure and function in the study of life science, but it is difficult to obtain by traditional reverse transcription. We employed a novel strategy to clone human leukemia inhibitory factor (hLIF) gene cDNA from genomic DNA, which was directly isolated from the mucous membrane of mouth. The hLIF sequence, which is 609 bp long and is composed of three exons, can be acquired within a few hours by amplifying each exon and splicing all of them using overlap-PCR. This new approach developed is simple, time- and cost-effective, without RNA preparation or cDNA synthesis, and is not limited to the specific tissues for a particular gene and the expression level of the gene.

Abstract
This study reported the analysis of KIT ligand (KITLG) gene polymorphisms in 681 goats of three breeds: Xinong Saanen (SN), Guanzhong (GZ), and Boer (BG). In addition, the study identified three allelic variants: g.769T>C and g.817G>T in SN and GZ breeds, and g.9760G>C in the three goat breeds. The g.769T>C and g.817G>T loci were closely linked (r(2) > 0.33). All the single nucleotide polymorphism loci were in Hardy-Weinberg disequilibrium (P < 0.05). Significant associations were found for litter size with all three loci. Therefore, these results suggest that the KITLG gene is a strong candidate gene affecting litter size in goats.

Abstract
OBJECTIVE To study the prevalence of Diabetes mellitus (DM) in children and adolescents and to describe the characteristics on age, gender and district distribution of schoolchildren, in Beijing. METHODS A cross-sectional screening program the fasting capillary blood glucose (FCBG) was carried out in 19,593 schoolchildren in 7 areas of Beijing from March to October, 2004. According to the WHO diagnostic criteria: DM was set as FCBG < or = 6.1 mmol/L, impaired fasting glucose (IFG) was set as 5.6 mmol/L < or = FCBG < 6.1 mmol/L. RESULTS The total aggregate age-adjusted prevalence rates of DM and IFG were 5.7 per thousand and 13.5 per thousand, respectively. The prevalence rates of DM and IFG in males were significantly higher than that in females (7.7 per thousand vs. 3.6 per thousand and 26.8 per thousand vs. 11.3 per thousand. DM X2 = 12.27, P = 0.0005; IFG X2 =47.29, P = 0.0000). Among seven districts, East District had the highest prevalence rates of DM and IFG, 8.9 per thousand and 27.4 per thousand (companied high obesity 28.68%) while Ping-Gu District having the lowest ones as 2.0 per thousand and 7.5 per thousand (obese 12.75%) respectively (X2 = 13.75, and X2 = 32.65, P = 0.0002 and P < 0.0001). The DM prevalence rates between districts ranged from 2.0 per thousand to 8.9 per thousand, X2 = 18.94, P = 0.004 and the IFG prevalence of districts ranged from 7.5 per thousand to 27.4 per thousand (X2 = 52.05, P < 0.0001). The prevalence rates of DM among different age groups increased with age, with the highest prevalence of IFG on the 10-14 age group. Among boys, the highest prevalence rates of DM and IFG fell in the 15-18 and 10-14 age groups respectively while the highest prevalence rates on both DM and IFG among girls were in the same age group 10-14. CONCLUSION The high prevalence rates on DM and IFG were seen in Beijing and showed significant discrimination on age, gender and district distribution. More developed urban district and males had a higher prevalence, companied by higher obesity prevalence. Age seemed to be a high risk factor on DM for boys while the puberty development seemed a high risk factor for girls.

Abstract
The nucleotide sequence of the Candida albicans ADE2 gene, which encodes phosphoribosylaminoimidazole carboxylase, has been determined. The sequence possesses an uninterrupted open reading frame of 1704 nucleotides corresponding to 568 amino acid residues. The deduced amino acid sequence shares a high degree of homology with ADE2 homologues in other fungal species including Saccharomyces cerevisiae, Pichia methanolica, Schwanniomyces occidentalis and Schizosaccharomyces pombe. Three regions of amino acid sequence were highly conserved among all reported ADE2 genes. The hexanucleotide TGACTC characteristic of genes involved in purine and amino acid biosynthesis is located in front of putative TATA boxes in the promoter region.

Abstract
In-vitro proteinase production by oral Candida albicans isolates from patients with and without HIV infection (18 isolates from each group) was assessed by image analysis of a plate assay, with bovine serum albumin (BSA) as a substrate. The effect of sub-minimal inhibitory concentrations (sub-MICs) of nystatin, amphotericin B, clotrimazole and miconazole on in-vitro proteinase production by these yeast isolates was also investigated. Proteinase production by C. albicans isolates from patients with HIV infection was significantly greater than production by those from individuals without infection. All 18 isolates from HIV-infected individuals produced proteinase, in comparison to 56% of isolates from uninfected individuals. Pre-exposure of C. albicans isolates (seven proteinase producers from each group) to 1/4 and 1/16 MICs of nystatin, amphotericin B, clotrimazole and miconazole resulted in decreased proteinase production in all isolates tested. However, after exposure to the four antimycotic agents, proteinase production was decreased to a significantly greater extent in isolates from uninfected individuals than in those with HIV disease. Furthermore, when the relative concentration effect of antimycotic agents on proteinase production was compared, C. albicans isolates from the HIV-free group demonstrated a salient dose-response relationship compared with the HIV-infected group. These results indicate that C. albicans from patients with HIV infection are significantly more proteolytic than those from individuals without the infection, and that polyenes and imidazoles curtail the proteolytic activity of all C. albicans isolates, albeit to a lesser extent in those from HIV-infected patients. It appears that HIV disease favours oral colonisation by more proteolytic C. albicans isolates, with resilient proteolytic activity.
