OBJECTIVE:
To investigate the correlation between serum vitamin D level and clinical outcomes after repair of rotator cuff tears.
METHODS:
A total 122 patients who met the inclusion criteria and were followed up for 12 months from March 2018 to March 2020 were analyzed retrospectively, including 50 males and 72 females with an average age of(62.10±8.39) years old (ranged, 34 to 82 years old). All patients were divided into deficiency group(vitamin D<20 μg/L) and control group(vitamin D≥20 μg/L), including 62 cases in the deficiency group, with vitamin D (14.80±3.18) μg/L;60 cases in the control group, with vitamin D(25.17±5.64) μg/L. The two groups were compared in terms of age, gender, body mass index(BMI), tear size, degree of retraction, degree of fatty infiltration, injury factors, postoperative pain VAS score, postoperative shoulder joint function score, and re-tear rate. The age of all patients was divided into two categories:<60 years old and ≥60 years old;BMI was divided into <24 kg/m2 and ≥ 24 kg/m2;tear size was divided into ≤3 cm and >3 cm;retraction degree was divided into ≤2 cm and >2 cm;fat infiltration was divided into ≤2 grade and >2 grade;and the course of the disease was ≤3 months and >3 months. The correlation between Sugaya re-tear type and the variables listed above were analyzed and calculated.
RESULTS:
There were no major complications such as joint infection, anchor withdrawal and revision surgery in any of the 122 patients who were followed up on. There were no statistical differences in age, gender, injury factor, BMI, tear size, degree of retraction, degree of fatty infiltration, and duration of disease between the two groups (P>0.05). The Constant-Murley scores, UCLA scores, and ASES scores of the two groups all improved considerably after surgery(P<0.05);however, there was no statistical differences in the postoperative shoulder function scores between the two groups (P>0.05). There was significant difference in VAS between the two groups 1 month and 3 months after operation, with vitamin D deficiency group scoring higher, and there was no significant differences 6 and 12 months after operation. Tear size(>3 cm), degree of retraction(>2 cm), degree of fatty infiltration(>2 degree) were all shown to be the independent risk factors for retear after surgery by Logistic regression analysis(P<0.05). The comparison between the two groups of patients using a 2×5 row list showed that the Sugaya classification of rotator cuff re-tear(grade Ⅰto Ⅴ) between the vitamin D deficiency group and the control group was statistically different(t=14.228, P=0.007). It was discovered that the Sugaya classification after surgery was statistically different between the two groups.
CONCLUSION
Vitamin D deficiency is not correlated with clinical function scores and re-tear rate, however it is associated with the early postoperative pain (1 and 3 months) and the quality of rotator cuff healing (Sugaya classification) after surgery.

OBJECTIVETo evaluate mid-term clinical results of microendoscopic discectomy (MED) for the treatment of lumbar disc hermiation.
METHODSIn the study, 117 patients were reviewed,including 63 male and 54 female, ranging in age from 24 to 72 years,with an average of 50.6 years. Among the patients, 60 patients had simple lumbar disc herniation, 10 patients had simple lateral crypt stenosis, 32 patients had lumbar disc herniation combined with lateral crypt stenosis, and 15 patients were combined with calcified nucleus pulposus. Two patients had herniation in L3-L4, 56 patients in L4-L5, 48 patients in L5-S1, 11 patients in L4-L5 and L5-S1. The central type of lumbar disc herniation occurred in 22 patients and the lateral type of herniation occurred in other 95 patients. The Protrusion type of herniation occurred in 32 discs, ruptured type in 73 discs, and free type in 12 discs. Ninety-eight patients had lumbar and leg pain in one side, and 19 patients in double sides. MED was used to remove the nucleus and decompress the nerve root canal.
RESULTSAll the patients were followed up and the duration ranged from 48 to 84 months,with an average of 5.5 years. According to lumbar and leg pain evaluation criteria from spinal group of Chinese Orthopaedic Association, there were 93 patients got an excellent result, 16 good and 8 poor.
CONCLUSIONAppropriate control indications and skillful surgical techniques are the key points to decrease the complication and to improve the curative effect.

Chinese Journal of Integrated Traditional and Western Medicine 2010;30(2):208-210
OBJECTIVETo study the influence of modified Shegan Mahuang Decoction (SGMH) on cytokines such as tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-10 and IL-13 in children suffered from cough and variant asthma (C&VA).
METHODSOne hundred and fifty-four children with C&VA were randomly assigned to two groups: 79 in the treatment group were medicated orally with SGMH one dose per day taking in twice; 75 in the control group were medicated with Montelukast once a day in dose of 4 mg for children aged from 2 to 5 years and 5 mg for those from 6 to 14 years, the medication for all was given 4 weeks. Serum contents of cytokines, including TNF-alpha, IL-10 and IL-13, in patients were measured before and after treatment. Besides, serum contents of these cytokines in 45 healthy children were measured for control.
RESULTSSerum levels of TNF-alpha and IL-3 in the treatment group were 2510 +/- 1500 ng/L and 60.76 +/- 23.67 ng/L, and in the control group, 2890 +/- 1410 ng/L and 61.56 +/- 20.37 ng/L, respectively, all were significantly higher than those of healthy (709 +/- 280 ng/L and 39.49 +/- 3.09 ng/L, P < 0.01); but level of IL-10 was significant lower in the two patient groups than that in control (1546 +/- 1434 ng/L and 1823 +/- 1314 ng/L vs 7123 +/- q2641 ng/L, P < 0.01). After treatment, the levels of TNF-alpha and IL-13 decreased and IL-10 increased significantly in the treatment group, and showed significant different to those in the control group respectively (960 +/- 420 ng/L, 43.67 +/- 12.37 ng/L and 6834 +/- 2216 ng/L vs 2610 +/- 1220 ng/L, 50.56 +/-19.56 ng/L and 2529 +/- 1223 ng/L, P < 0.01). Clinical efficacy between groups also showed that the total effective rate in the treatment group was significantly better (86.07% vs. 42.67%, P < 0.01).
CONCLUSIONSGMH can regulate the serum levels of TNF-alpha, IL-10 and IL-13, and shows evident clinical effect in treating children's C&VA.

Objective To investigate the effects of PTD4-GFP-Apoptin protein on proliferation inhibition and apoptosis-inducing of different types of leukemia cells. Methods Genetic engineering was used to restructure a carrier containing PTD4-GFP-Apoptin gene, and MTT was applied to detect the expressed PTD4-GFP-Apoptin fusion protein and its effect on the leukemia cell proliferation. Flow cytometry (FCM) was used to detect the effects on cell apoptosis. Results MTT cell proliferation inhibitory experiment showed that PTD4-GFP-Apoptin had different degree of proliferation inhibition on different types of leukemia cells;furthermore, the inhibitory effect presented positive correlation with time and concentration. FCM showed that PTD4-GFP-Apoptin had apoptosis-inducing effect on HL-60 cells, and the apoptotic rate had significant difference compared with the control group (P <0.05). Conclusions PTD4 can carry large proteins to penetrate the cell membrane, and PTD4-GFP-Apoptin may produce the inhibiting proliferation in vitro for a variety of leukemia cells. Apoptin can induce tumor cell apoptosis without affecting normal cells, which might become a new agent for the clinical treatment of leukemia.

Objective To investigate the associations of variants in signal transducer and activator of transcription 4 (STAT4) in Chinese Han population with rheumatoid arthritis (RA). Methods The study was performed in 228 RA cases and 228 controls. Haplotypes from the HapMap database Chinese population were used to select tag-single-nucleotide polymorphisms (SNPs) (r2=0.9) in STAT4 gene. Twenty-three SNPs located in STAT4 gene were examined by multiplex polymerase chain reaction (PCR) and matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS). The Hardy-Weinberg equilibrium (HWE) was tested by a chi-square and Fisherˊs analysis. Differences in genotypes of the STAT4 polymorphism variants were evaluated using a Chi-square test. All statistical analyses were done with Haploview 4.1 software. Results Significant difference was detected in three SNPs (rs11685878, rs129888 and rs16833437) in allele frequencies analysis (χ2=6.014 8, 4.024 8, 5.539 1, P<0.05). Association was detected for three SNPs (rs11685878, rs16833437 and rs12988825) in genotype analysis ( χ2=6.814 9, 6.098 7, 6.691 7, P<0.05). Conclusion STAT4 may associate with susceptibility in Chinese Han population.

BACKGROUND:Shengji Yuhong col agen showed good curative effect of promoting angiogenesis and tissue healing compared with Shengji Yuhong Gao and col agen alone or gelatin alone.
OBJECTIVE:To explore the curative effect and mechanism of subcutaneous implantation of Shengji Yuhong col agen in rabbits in promoting angiogenesis and repair.
METHODS:Shengji Yuhong col agen as the experimental group and collagen as the control group was implanted inside the rabbit subcutaneous pockets of the back of New Zealand rabbits. The implanted samples and
surrounding tissues were obtained at 3, 7, 14, 28 and 56 days fol owing surgery. Pathological sections were made and the repair of surrounding tissue was observed. Hemoglobin levels in col agen were measured.
Immunofluorescence and CD34 dyeing marking method were utilized to observe capil ary angiogenesis. Western blot assay was employed to examine vascular endothelial growth factor and angiogenin-1 expression.
Immunohistochemistry was used to observe the secretion of typeⅠ and Ⅲ col agen on the surrounding tissues.
RESULTS AND CONCLUSION:The experimental group showed increased subcutaneous vascularization. There were reduced inflammatory exudation, granulation tissue hyperplasia, and mature fiber connective tissue at 28 days.
Angiogenesis and hemoglobin contents were greater in the experimental group than in the control group (P<0.05 or P<0.01). At 3 and 7 days fol owing surgery, vascular endothelial growth factor and angiogenin-1 expression was greater in the experimental group than that in the control group (P<0.05 or P<0.01). The secretion of type Ⅰ col agen was
identical between the experimental and control groups. However, the secretion of type Ⅲ col agen was higher in the experimental group than in the control group at 28 and 56 days (P<0.05), and the proportion of type Ⅰ and Ⅲ
col agen was lower in the experimental group than in the control group at 28 and 56 days (P<0.01). These suggested that Shengji Yuhong col agen can significantly promote angiogenesis in the surrounding tissues with the possible
mechanisms of adjusting the protein expression of vascular endothelial growth factor and angiogenin-1. At the same time, it has the function of regulating col agen formation with better ratio of typeⅠ and type Ⅲ col agen to acquire higher
quality of wound healing with reduced scar formation.

Objective To evaluate the effects of Chuanglingye decoction on angiogenesis and wound healing. Methods With a series of dosages of Chuanglingye decoction, their optimal effects of angiogenesis were searched for through the chicken embryo allantois membrane model(CAM). The vascular endothelial cell proliferation experiment (MTT) and the migration assay were used for the detection of effects. The gauze loading with Chuanglingye decoction of 0.2 ml as the experimental group and with saline of 0.2ml as the control group were applied on the total skin mechanical round wound of 1.5cm diameter and changed every other day. The sizes of area were detected on the day of 0,3,7,14 and 28 as well as the scores of inflammatory response, contains of TNF-αand Il-6 were detected on the day of 3 and 7. Results The CAM experiments showed that the angiogenic effects of 0.2 ml and 0.3 ml dosage of the Chuanglingye group were significantly lower than those of the control group(P<0.05). The 0.2 ml dosage of Chuanglingye decoction was chosen for the further experiment. The HUVEC proliferation rate of the experimental group decreased 21%, as compared with the results of control group. The cell migration movement of 12 hours, 24 hours in the experimental group were significantly lower than those in the control group. For theanimal experiments, the area sizes of the wound were similar in the experimental and control group without any significant differences. The scores of inflammatory response and contains of TNF-α(768±107)ng/L,(380±47)ng/L and Il-6(664±133)ng/L,(363±43)ng/L in the experimental group were significant decreased than those of the control group on the day of 3(958± 140)ng/L,(2215±314)ng/Land 7(512±62)ng/L,(1562±174)ng/L. Conclusion It showed that Chuanglingye decoction had negative effects on vascular endothelial cell migration and proliferation and thus inhibiting angiogenesis. These effects did not infer the process of the wound healing due to its ameliorating the inflammatory response which may be a help to wound healing.

Objective:To investigate the effect of interleukin-33 (IL-33) on lipopolysaccharide (LPS)-induced permeability of rat cardiac microvascular endothelial cells (RCMECs).Methods:RCMECs were cultured in vitro to be divided into control group, LPS group, IL-33 group and LPS+IL-33 group. The effect of IL-33 on the proliferation of RCMECs was detected by cell counting reagent (CCK8). Fluorescein isothiocyanate (FITC)-dextran assay was used to evaluate the permeability of RCMECs. The expression of vascular endothelial calmodulin, ras homologous gene family (Rho) member A (RhoA) and phosphorylated Rho-associated coiled-coil-containing protein kinase (p-ROCK2) proteins were tested by western blot. High-throughput sequencing and gene ontology (GO) were performed for gene expression in LPS and LPS+IL-33 groups.Results:No significant effect of IL-33 at 10-50 ng/ml on the proliferation of RCMECs was observed ( P>0.05). Compared with the control group, the permeability of RCMECs (permeability coefficient ratio 1.404±0.029 vs. 1.000±0.200, P<0.05) was significantly increased in LPS group and the expression of vascular endothelial calmodulin (relative gray value 0.429 5±0.012 9 vs. 0.594 9±0.014 2, P<0.05) was down-regulated, while the permeability of monolayers (permeability coefficient ratio, 0.948±0.013, P<0.01) was decreased in LPS+IL-33 group and the expression of vascular endothelial calmodulin (relative grayscale value 0.549 1±0.012 0, P<0.005) was up-regulated compared with the LPS group. High-throughput sequencing data revealed that the differential genes downregulated in the LPS and LPS+IL-33 groups were associated with cytoskeleton and Rho signaling pathway. Compared with the control group, RhoA (relative gray value 0.211 4±0.009 9 vs. 0.135 0±0.007 6, P<0.000 1) and p-ROCK (relative gray value 0.656 3±0.013 2 vs. 0.503 6±0.036 2, P<0.000 1) protein expression was upregulated in the LPS group. When compared with LPS group, RhoA (relative gray value 0.157 7±0.010 7, P=0.000 2), p-ROCK (relative gray value 0.427 7±0.003 8, P<0.000 1) protein expression was decreased in LPS+IL-33 group. Conclusion:IL-33 may improve LPS-induced hyperpermeability of RCMECs by inhibiting RhoA and p-ROCK protein expression in Rho/Rho-associated coiled-coil-containing protein kinase signaling pathway.
