ABSTRACT

OBJECTIVE@#To explore the genetic basis for a Chinese pedigree affected with X-linked retinoschisis.@*METHODS@#Clinical data of the pedigree was collected. Following DNA extraction, PCR and Sanger sequencing were carried out to detect potential variant in the RS1 gene. The result was verified by using PCR and restriction fragment length polymorphism assay.@*RESULTS@#All male patients were found to harbor a c.458T>G (p.Val153Gly) variant of the RS1 gene, for which Their mothers were heterozygous carriers. The same variant was not detected among unaffected members of the pedigree as well as 100 healthy controls. Bioinformatic analysis suggested the variant to be pathogenic.@*CONCLUSION@#The c.458T>G (p.Val153Gly) variant of the RS1 gene probably underlay the X-linked retinoschisis in this pedigree.

ABSTRACT

Objective To explore the clinical characteristics and treatment of Pseudomonas peritoneal dialysis-associated peritonitis(PsP). Methods The data of patients receiving peritoneal dialysis in four tertiary hospitals in Jilin province from 2015 to 2019 were retrospectively analyzed.According to the etiological classification,the patients with peritoneal dialysis-associated peritonitis(PDAP)were classified into PsP group and non-PsP group.The incidence of PsP was calculated,and the clinical characteristics and treatment outcomes of the two groups were compared.Kaplan-Meier method was used to draw the survival curve,and Cox regression was performed to analyze the risk factors affecting the technical failure of PsP.The treatment options of Pseudomonas aeruginosa-caused PDAP and the drug sensitivity of PsP were summarized. Results A total of 1530 peritoneal dialysis patients with complete data were included in this study,among which 439 patients had 664 times of PDAP.The incidence of PsP was 0.007 episodes/patient-year.PsP group had higher proportion of refractory peritonitis(41.38% vs.19.69%,P=0.005),lower cure rate(55.17% vs.80.79%, P=0.001),and higher extubation rate(24.14% vs.7.09%,P=0.003)than non-PsP group.The technical survival rate of PsP group was lower than that of non-PsP group(P<0.001).Multivariate Cox regression analysis showed that Pseudomonas aeruginosa was an independent risk factor for technical failure in patients with PsP(HR=9.020,95%CI=1.141-71.279,P=0.037).Pseudomonas was highly sensitive to amikacin,meropenem,and piperacillin-tazobactam while highly resistant to compound sulfamethoxazole,cefazolin,and ampicillin. Conclusion The treatment outcome of PsP is worse than that of non-PsP,and Pseudomonas aeruginosa is an independent risk factor for technical failure of PsP.

ABSTRACT

Objective:To investigate the incidence, drug sensitivity and drug resistance characteristies, and theraputic effect of staphylococcal peritoneal dialysis-associated peritonitis (PDAP), aim to provide clinical evidences for standardizing treatment therapy of staphylococcal PDAP. Methods:Clinical data of PDAP patients admitted to the Second Hospital of Jilin University, the First Hospital of Jilin University-the Eastern Division, Jilin Central Hospital and Jilin First Automobile Work General Hospital during January 1, 2013 and December 31, 2019 were retrospectively collected. The results of etiology, drug sensitivity and drug resistance of staphylococcal PDAP patients were collected. According to the pathogenic bacteria, patients were divided into staphylococcus aureus group ( n=48) and coagulase-negative staphylococcus group ( n=232). According to the results of methicillin resistance, patients were divided into drug-resistant group ( n=71) and drug-sensitive group ( n=30). The prognosis of antibiotic therapy in each group were compared. Poisson regression was used to test the changing trend of the incidence of staphylococcal PDAP. The changes of drug sensitivity and drug resistance of staphylococcus were compared between 2013 and 2019 by linear trend χ2 test. Results:A total of 1 085 cases of PDAP occurred in 625 patients were screened, and 280 cases of staphylococcal PDAP were finally included. The incidences of staphylococcal PDAP, staphylococcus aureus PDAP and coagulase-negative staphylococcal PDAP were 0.063 times per patient year, 0.010 times per patient year and 0.053 times per patient year respectively. In addition, the incidence of PDAP caused by staphylococcus, staphylococcus aureus and coagulase-negative staphylococcus decreased year by year (all P<0.05). With the change of years, the sensitivity rate of staphylococcus to rifampicin increased, while the sensitivity rate of staphylococcus to moxifloxacin decreased (both P<0.05). The drug resistance rate of staphylococcus to levofloxacin increased ( P<0.05). The staphylococcus aureus group was more prone to refractory PDAP and catheter removal than that in coagulase-negative staphylococcus group, and the recurrence rate was higher than that in coagulase-negative staphylococcus group (all P<0.05). The proportion of vancomycin used during the whole course of antibiotic therapy in drug-resistant group was higher than that in drug-sensitive group ( P<0.05). Conclusions:The incidence of staphylococcal PDAP decreases year by year, and the drug sensitivity characteristics of staphylococcus also change. The therapeutic outcomes of staphylococcus aureus PDAP are worse than that of coagulase-negative staphylococcus.

ABSTRACT

CNKI, PubMed and other databases were retrieved to extract eligible randomized controlled trial(RCT) about modified Xuefu Zhuyu Decoction(MXZD) combined with Western medicine(trial group) versus Western medicine alone(control group) in the treatment of leiomyoma. Therefore, a total of 25 RCTs were included, involving 2 328 patients. Bias risk evaluation tool in Cochrane Handbook 5.1.0 was used for evaluating the quality of these RCTs. Meta-analysis was performed for the reported indicators, including total efficiency, serum hormone level [progesterone(P), luteinizing hormone(LH), estradiol(E_2), follicle stimulating hormone(FSH)], uterine size, fibroids size and adverse reactions by using Stata 14.0 software. Meta-analysis showed that the total efficiency(RR=1.21,95%CI[1.17,1.25],P<0.05) of trial group was better than that of control group. Serum hormone level(WMD_P=-3.86,95%CI[-4.31,-3.41],P<0.05; WMD_(LH)=-3.64,95%CI[-4.47,-2.82],P<0.05; WMD_(E_2)=-39.99,95%CI[-53.45,-26.52],P<0.05; WMD_(FSH)=-3.79,95%CI[-4.86,-2.72],P<0.05), uterine size(WMD=-50.02,95%CI[-55.98,-44.06],P<0.05), fibroids size(WMD=-15.79,95%CI[-18.11,-13.46],P<0.05) and adverse reactions(RR=0.65,95%CI[0.48,0.88],P<0.05) of trial group were all lower than those of control group, with statistical significances. Trial sequential analysis(TSA) was performed by using TSA 0.9 software, and showed a reliable therapeutic effect of the experimental group. In short, our study indicated that modified Xuefu Zhuyu Decoction combined with Western medicine had a better therapeutic effect on leiomyoma than Western medicine alone, but more high-quality studies are needed to verify this conclusion in the future.

ABSTRACT

Objective To investigate the pollution level of 9,10-anthraquinone in teas sold in Wuhan, and to assess the dietary exposure of 9,10-anthraquinone ingested through tea. Methods The content of 9,10-anthraquinone in teas collected from local tea markets in Wuhan was analyzed by GC-MS/MS. Results 9,10-anthraquinone was detected in all 36 tea samples with a concentration ranging from 0.0080 mg/kg to 0.137 mg/kg. The standard limit for 9,10-anthraquinone has not yet been set in China. Referring to EU standards, the total over-standard rate was 86.11% (31/36). Generally, the concentration of residual 9,10-anthraquinone was higher in highly fermented teas. The highest average concentration of residual 9,10-anthraquinone was found in fully/post-fermented tea (0.0762 mg/kg), and the over-standard rate was 100%. The second highest was in semi-fermented tea (0.0452 mg/kg), and the over-standard rate was 86.7%. The concentration of 9,10-anthraquinone in non-fermented tea was 0.0262 mg/kg, and the over-standard rate was 42.9%. According to people’s tea-drinking habits, tea samples were brewed with boiling water(1:50)for 5 minutes, and the concentration of 9,10-anthraquinone in tea soup was 0.0004 mg/kg~0.01 mg/kg, with an average leaching rate of 7.2%. The average daily intake exposure of tea for an adult was 0.0551μg/kg bw/day. Conclusion There was a certain degree of 9,10-anthraquinone pollution in the teas sold in Wuhan, and the rate exceeding the standard was high. Since the acceptable daily intake (ADI) for 9,10-anthraquinone has not been established, it is impossible to assess the health risks of 9,10-anthraquinone ingested through tea.

ABSTRACT

The poor stability of the ligustilide (LIG) makes its quantitation in Angelica sinensis (AS) difficult. This study establishes a chemical conversion method for the determination of ligustilide content in AS and proposes a national pharmacopoeia standard. Mechanical agitation and sonication of a powdered AS extract in a methanol/cyprolamine mixture facilitated the stabilization and transformation of ligustilide. Using an external reference HPLC-DAD method, the cyclopropyl-ligustilide (LIGc) content in the mixture could be determined. The content of ligustilide was greater than 1.0% based on 144 AS specimens including 68 obtained from the originally planted areas of Qinghai and Gansu Province; 55 specimens were obtained from Minxian and Weiyuan County medicine markets, and 21 specimens for which the storage period reached or exceeded 1.5 years. According to the Hong Kong Chinese materis medica standards, the content of ligustilide in AS should not be lower than 0.6%. The developed method could also be applied to the quality control of other Chinese medicinal materials (such as Ligusticum chuanxiong) or Chinese patent medicines in which ligustilide is the main component.

ABSTRACT

Objective:To determine the epidemiological characteristics and incidence trends of sexually transmitted diseases (STD) in Mengla County of Yunnan Province, and provide evidence for future prevention and control of STD. Methods:STD case information from 2005 to 2017 was extracted from the National Notifiable Infectious Disease Report Information System. Data were collected by year and disease type,and the incidence rate, epidemic characteristics and suspicious contact history of STD were statistically analyzed. Results:A total of 1 251 STD cases were reported in Mengla county from 2005 to 2017, including 490 gonorrhea, 483 syphilis, 216 condyloma acuminatum, 16 genital chlamydial infection and 46 genital herpes. The average annual incidence of STD was 35.57/100 000. The majority of STD cases were 20-29 years old (n=541,43.25%), married (n=603,48.20%), Han people (n=638,50.10%), with education of middle school (n=536,42.85%), and occupation of farmers (n=702, 56.12%). The 42.61% of STD cases had non-marital sexual contact history, in which the proportion was significantly higher among male (55.05%) than female (28.98%). In addition, the proportion of non-marital sex among STD cases increased gradually by year and significantly differed. Conclusion:The epidemic status of STD in Mengla county is relatively low. However, STD incidence increased gradually by year, which warrants more and specific measures on the STD control and prevention.

ABSTRACT

Objective:To study the relationship between the expression of tumor markers and radical resection in patients with gastric cancer.Methods:The medical records of gastric cancer patients undergoing surgery in Department of Gastrointestinal Surgery, Puji District, Dongguan People′s Hospital Affiliated to Southern Medical University from June 2018 to December 2019 were retrospectively analyzed, and 136 patients were selected.Collected patient data, including general information, the expression levels of tumor markers carcinoembryonic antigen(CEA), carbohydrate antigen 19-9(CA19-9), carbohydrate antigen 72-4(CA72-4), and the surgical method used.The relationship between the expression of tumor markers and radical resection was observed.Results:There was no statistically significant difference in the radical resection rate of gastric cancer in different genders, ages, and locations of gastric cancer (all P>0.05). TNM classification (tumor node metastasis classification) stage III patients had a lower radical resection rate (63.3%(38/60)) than stage I (100%(27/27)) and II (100%(49/49)) (χ 2=58.166 and 81.208, P<0.001). The radical resection rate of CEA(+ ) patients (47.8%(44/92)) was lower than that of CEA(-) patients (90.9%(40/44))(χ 2=23.394, P<0.001). The radical resection rate of CA19-9(+ ) patients (47.7%(42/88)) was lower than that of CA19-9(-) patients(87.5%(42/48))(χ 2=20.804, P<0.001). The radical resection rate of CA72-4(+ ) patients (54.3%(51/94)) was lower than that of CA72-4(-) patients (78.6%(33/42)) (χ 2=7.268, P=0.007). The variables with P<0.1 in univariate analysis were included in the logistic regression model, including 4 variables including TNM stage, CEA, CA19-9, and CA72-4.The results showed that TNM staging ( OR=1.169, 95% CI=0.925-1.634, P=0.001), CEA ( OR=1.067, 95% CI=1.364-4.338, P=0.024), CA19-9( OR=3.012, 95% CI=1.679-6.317, P=0.007), and CA72-4 were independent risk factors for radical resection( OR=5.364, 95% CI=0.675-3.224, P=0.004). The number of positive expressions of tumor markers was negatively correlated with the radical resection rate ( r=-0.621, P<0.05). The expression levels of CEA, CA19-9, and CA72-4 in patients with radical resection were 75.36(3.76, 198.20)μg/L, 152.76(34.81, 241.09)kU/L, 126.60(4.01, 218.07)kU/L, respectively.The expression levels of CEA, CA19-9, and CA72-4 in the radically resected patient group were 173.65(120.78, 254.87) μg/L, 255.88(102.45, 395.11) kU/L, 201.71(79.15, 325.92)kU/L.The expression level of CEA, CA19-9, CA72-4 in the group with radical resection were lower than that in the group with no radical resection, and the difference was statistically significant (the Z values were 10.672, 8.945, 9.862, all P<0.001). ROC curve showed that AUC of CEA, CA19-9 and CA72-4 were 0.627, 0.714 and 0.768, respectively.The best cut-off value of CA72-4 was 87.62 kU/L, the sensitivity was 88.1% (74/84) and the specificity was 90.4% (47/52). Conclusion:The expression levels and number of tumor markers CEA, CA19-9, CA72-4 in patients with gastric cancer were correlated with the risk of radical resection.

ABSTRACT

BACKGROUND@#Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease.@*OBJECTIVE@#This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m@*MAIN OUTCOME MEASURES@#The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment.@*RESULTS@#A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group.@*CONCLUSION@#SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone.@*TRIAL REGISTRATION NUMBER@#NCT02063100 on ClinicalTrials.gov.

ABSTRACT

Objective:To investigate the clinical characteristics of E. coli peritoneal dialysis-associated peritonitis (PDAP) and the risk factors for its occurrence and treatment failure.Methods:The clinical data of patients with episodes of PDAP in four general hospitals in Jilin Province from 2013 to 2019 were retrospectively reviewed. According to the pathogenic bacteria, the patients were divided into E. coli and non- E. coli groups. The incidence of E. coli PDAP in the last seven years was calculated and the clinical characteristics were compared between two PDAP groups. Logistic regression was used to analyze the risk factors for the occurrence and treatment failure of E. coli PDAP. Results:A total of 693 PDAP episodes/cases were enrolled in this study, including 100 episodes/cases in the E. coli group and 593 episodes/cases in the non- E. coli group. The incidence rate of E. coli PDAP in the four hospitals showed a decreasing trend during 2013 to 2019. Compared with the non-E.coli group, the proportion of diabetic patients and the average blood albumin levels in the E. coli group were lower ( χ2=5.006, Z=-2.992, P<0.05), while the proportion of refractory peritonitis was higher, and the duration of antibiotic therapy was longer ( χ2=6.350, Z=-2.779, P<0.05). Multivariate Logistic regression analysis showed that history of PDAP ( OR=1.577, 95% CI: 1.015-2.448) and low baseline serum albumin level ( OR=0.958, 95% CI: 0.923-0.995) were independent risk factors for the development of E. coli PDAP, while concomitant diabetes was an independent protective factor for E. coli PDAP ( OR=0.538, 95% CI: 0.330-0.876). Moreover, long-term dialysis was an independent risk factor for treatment failure of E. coli PDAP ( OR=1.047, 95% CI: 1.018-1.076). Conclusion:The incidence rate of E. coli PDAP in study institutions has declined in the past 7 years, but the rate of refractory PDAP is still high. The history of PDAP and low blood albumin level are independent risk factors for the occurrence of E. coli PDAP, while concomitant diabetes is an independent protective factor for the occurrence of E. coli PDAP. Long-term dialysis is an independent risk factor for treatment failure of E. coli PDAP.

ABSTRACT

@#To explore the effect of IL-33 on various tumor types,exogenous injection of recombinant mouse IL-33 protein (mIL-33) was used to study the efficacy of different subcutaneous tumor-bearing mouse models. In this study,mIL-33 has been found to significantly inhibit the growth of liver,lung,gastric,prostate,and colon cancers. However,the inhibition of tumor growth by mIL-33 was not completely consistent in different types of tumor. A lower dose of mIL-33 (10 μg/kg) significantly inhibited tumor growth in subcutaneous tumor-bearing mice of liver,lung,and gastric cancers,while a higher dose of mIL-33 (90 μg/kg) was required to exert the corresponding antitumor effect in subcutaneous tumor-bearing mouse models with prostate and colon cancers. In addition,the growth inhibitory effect of mIL-33 on subcutaneous tumors of colon cancer was also correlated with the duration of administration and the stage of tumor progression. The results of this study indicate that mIL-33 significantly inhibits the growth of a variety of tumors,suggesting that IL-33 might be an effective target for tumor treatment.

ABSTRACT

OBJECTIVE@#To study the clinical screening and genetic diagnosis of children suspected of Prader-Willi syndrome (PWS), as well as the differences in the scores of clinical diagnostic criteria among the children with a confirmed diagnosis of PWS.@*METHODS@#A total of 94 children suspected of PWS who were admitted from July 2016 to December 2018 were enrolled as subjects. Methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) was performed to confirm the diagnosis. For the children with a confirmed diagnosis of PWS, the scores of clinical diagnostic criteria were determined, and the perinatal characteristics were analyzed.@*RESULTS@#A total of 11 children with PWS were confirmed by MS-MLPA, with a detection rate of 12%, among whom there were 7 boys and 4 girls, with a median age of 3 years and 4 months (range 25 days to 6 years and 8 months) at the time of confirmed diagnosis. Among the 11 children with PWS, only 5 children (45%) met the criteria for clinical diagnosis. The main perinatal characteristics of the children with PWS were decreased fetal movement (9 cases, 82%), cesarean section birth (11 cases, 100%), hypotonia (11 cases, 100%), feeding difficulties (11 cases, 100%), and weak crying (11 cases, 100%).@*CONCLUSIONS@#Gene testing should be performed as early as possible for children suspected of PWS by clinical screening. PWS may be missed if only based on the scores of clinical diagnostic criteria.

ABSTRACT

Three bibenzyls 1-3 and six other compounds 4-9 were firstly isolated from Dendrobium huoshanense stems. They were identified as 3',4-dihydroxy-3,5'-dimethoxybibenzyl(1), batatasin Ⅲ(2), 3,4'-dihydroxy-5-methoxy bibenzyl(3), dihydroconiferyl dihydro-p-coumarate(4), syringaresinol(5), 3-(4-hydroxyphenyl)-propionic acid ethyl ester(6),(3-ethylphenyl)-1,2-ethanediol(7),(S)-5-hydroxy-3,4-dimethyl-5-pentylfuran-2(5H)-one(8) and loliolide(9). Anti-inflammation assay showed that bibenzyls 1-3 could significantly inhibit the production of nitric oxide(NO) and the expression of tumor necrosis factor α(TNF-α) and interleukin 1β(IL-1β) mRNA in LPS-induced RAW264.7 macrophages. Mechanism study exhibited that the phosphorylation of nuclear factor kappa B(NF-κB) p65, inhibitor of κB(IκB), extracellular regulatedprotein kinase(ERK), c-Jun N-terminalkinase(JNK), p38 and Akt of LPS-induced RAW264.7 macrophages could be remarkably reduced by 1. These results suggested that the inflammatory response of LPS-induced RAW264.7 macrophages could be significantly inhibited by 1-3. Additionally, the anti-inflammatory effect of 1 might be contributed to its ability on the regulation of NF-κB, MAPKs and Akt signaling pathways.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for a patient featuring multiple carboxylase deficiency (MCD).@*METHODS@#PCR and Sanger sequencing were used to detect variant in the coding region of BT and HLCS genes in the patient. Suspected variants were verified in her parents and 80 unrelated healthy controls by a PCR-restriction fragment length polymorphism (PCR-RFLP) method.@*RESULTS@#The patient was found to carry compound heterozygous variants of the HLCS gene, namely c.286delG (p.Val96Leufs*162) and c.1648G>A (p.Val550Met). The c.286delG (p.Val96Leufs*162) was verified to be novel variant based on the result of PCR-RFLP analysis. No variant was found in the coding regions of BT gene in the patient.@*CONCLUSION@#The compound c.286delG (p.Val96Leufs*162) and c.1648G>A (p.Val550Met) variants probably underlie the MCD disorder in this patient. Above results have enriched the variant spectrum of MCA.

ABSTRACT

The aim of this paper was to investigate the immunosuppressive effects of dihydroartemisinin and Huobahua compatibility in mice with delayed hypersensitivity and explore its possible mechanism. The delayed-type hypersensitivity(DTH) model in mice was established to observe the immunosuppressive effects of dihydroartemisinin and Huobahua compatibility in DTH mice. ELISA assay was used to detect the contents of interferon(IFN-γ); histopathological changes and degree of mononuclear infiltration of right ear tissues were examined by HE staining; the expression level of intercellular cell adhesion molecule-1(ICAM-1) in the right ear of mice was detected by immunohistochemistry; the protein expression levels of p38 phospho mitogen activated protein kinase(p-p38 MAPK) was detected by Western blot analysis. As compared with the control group, the degree of ear swelling, thymus/spleen index, serum IFN-γ as well as the number and degree of infiltration of monocytes were significantly increased in the model group. As compared with the model group, the degree of ear swelling and thymus/spleen index of the mice in the combination group were significantly reduced; the number and degree of infiltration of monocytes were significantly relieved; the serum levels of IFN-γ and the expression levels of p-p38 MAPK and ICAM-1 proteins in the right ear were also significantly reduced. The combination of dihydroartemisinin and Huobahua can significantly inhibit the DTH response, and it may regulate the production and secretion of related inflammatory factor IFN-γ by inhibiting the phosphorylation activity of p38 MAPK, thereby further reducing the expression of ICAM-1 and thus exerting the immunosuppressive effect.

ABSTRACT

OBJECTIVE@#To explore the effective therapy for treating chronic scapulohumeral periarthritis of cold-damp stagnation.@*METHODS@#A total of 90 cases of patients with chronic scapulohumeral periarthritis of cold-damp stagnation were randomly divided into an acupuncture and moxibustion group, a herbal cake separated moxibustion group and a routine rehabilitation group, 30 cases in each group. The routine rehabilitation group was treated with diclofenac sodium sustained-release tablets (0.1 g each time, taken after breakfast) and rehabilitation exercise, once a day. On the basis of the treatment in the routine rehabilitation group, the herbal cake separated moxibustion group was treated with herbal cake separated moxibustion at the affected side of Jianyu (LI 15), Jianliao (TE 14) and Jianzhen (SI 9), once a day. On the basis of the treatment in the herbal cake separated moxibustion group, the acupuncture and moxibustion group was additionally given umbrella shaped acupuncture with round sharp needle at the affected side of Jianyu (LI 15), Jianliao (TE 14), Jianzhen (SI 9), Naohui (TE 13), Jianqian (Extra), Jugu (LI 16), etc. once every other day. Each group was treated for 10 d. Before and after treatment the pain visual analogue scale (VAS) score and activities of daily living (ADL) score, and degree of changes in shoulder joint activity were compared in each group, and the clinical effect was evaluated.@*RESULTS@#After treatment, the pain VAS scores of three groups were decreased (@*CONCLUSION@#On the basis of routine rehabilitation training, herbal cake separated moxibustion combined with umbrella shaped acupuncture with round sharp needle treating chronic scapulohumeral periarthritis of cold-damp stagnation can significantly reduce shoulder joint pain and improve shoulder joint function.

ABSTRACT

Objective To investigate the nutrient contents of various grains in Hubei Province, and to provide a scientific basis for a balanced diet. Methods Various grains (except potatoes and beans) on the market in Hubei Province were collected. The samples were prepared by peeling and milling, or directly milling, and the nutrient contents were determined according to the national standard methods. With reference to the American nutrient profiling model, protein, dietary fiber, vitamin C, vitamin A, vitamin E, potassium, magnesium, iron and calcium, the nine nutrients were selected as recommended nutrients, and sodium, added sugars and fat were restricted nutrients. On the basis of 100 g for calculation, a nutrient-rich food model (Nutrient-rich foods, NRF9.3) was established and applied to evaluate the grains. Results The evaluation results showed that wheat and buckwheat grains contained a higher recommended nutrient content than restricted nutrient content, and had higher nutritional value. Among them, quinoa (black) had the highest NRF index of 102.4, indicating the most nutritional value. After peeling, the loss rate of nutrient value (NRF9.3 index) of various grains was 38.73% to 65.00%. Conclusion It is recommended that people should try to choose whole grains when purchasing grain products.
