OBJECTIVE: To explore the manifestations of jingjin (sinews/fascia) lesions and summarize their distribution rules in the patients with neck-type cervical spondylosis so as to provide the evidences for the development of clinical diagnosis and treatment scheme of acupuncture for cervical spondylosis. METHODS: A total of 120 patients with neck-type cervical spondylosis were collected. The meridian diagnostic method was used to examine the upper back of each patient, the manifestation category of jingjin lesions, locations and the affected muscle regions of twelve meridians were recorded. RESULTS: (1) The punctate lesions of jingjin were detected in 15 regions, and the highest frequency of lesion occurred in the region from the inner upper corner of the scapula to Quyuan (SI 13) (113 cases, 94.2% of lesion frequency). The lesion frequency of 10 regions was ≥50.0%. The punctate lesions were mainly distributed in the muscle regions of hand-shaoyang (349 cases) and foot-taiyang (333 cases). (2) The linear lesions of jingjin were detected in 10 regions, and the highest frequency of lesion occurred in the region from the inner upper corner of the scapula to Quyuan (SI 13) (77 cases, 64.2% of lesion frequency). The lesion frequency of 2 regions was ≥50.0%. The linear lesions occurred mainly in the muscle region of foot-taiyang (251 cases). (3) Eight regions were examined to be the planar lesions of jingjin, and the highest frequency of lesion was found in the site of Jianjing (GB 21) (84 cases, 70.0% of lesion frequency). The lesion frequency of 3 regions was ≥50.0%. The muscle region of foot-taiyang (260 cases) was predominated in the planar lesions. (4) The distribution of all of the punctate, linear and planar lesions of jingjin was analyzed statistically. It was found that 25 regions were involved and those with the high lesion frequency were distributed in the area from the inner upper corner of the scapula to Quyuan (SI 13), the sites of Jianjing (GB 21) and Dazhui (GV 14), transverse processes of C₃ to C₅ and the area from the lateral border of the scapula to the teres minor, separately. The muscle regions of foot-taiyang, hand-shaoyang and hand-yangming were involved in various kinds of jingjin lesions. CONCLUSION Jingjin lesions in patients with neck-type cervical spondylosis can be divided into three categories, namely, punctate, linear and planar lesions; of which, the punctate lesions are dominated. A majority of jingjin lesions is related to the muscle region of foot-taiyang, and the lesion frequency is higher compared with the lesions to the muscle regions of hand-shaoyang and hand-yangming. Jingjin lesions are commonly distributed in the area from the inner upper corner of the scapula to Quyuan (SI 13).

Objective: This study aimed to assess the technical feasibility, efficacy, and safety of the safe triangular working zone (STWZ) approach applied in percutaneous vertebroplasty (PV) for spinal metastases involving the posterior part of the vertebral body. Materials and Methods: We prospectively enrolled 87 patients who underwent PV for spinal metastasis involving the posterior part of the vertebral body, with or without the STWZ approach, from January 2019 to April 2022. Forty-nine patients (27 females and 22 males; mean age ± standard deviation [SD], 57.2 ± 11.6 years; age range, 31–76 years) were included in group A (with STWZ approach), accounting for 54 vertebrae. Thirty-eight patients (18 females and 20 males; 59.1 ± 10.9 years; 29–81 years) were included in group B (without STWZ approach), accounting for 57 vertebrae. Patient demographics, procedure-related variables, and pain relief as assessed using the visual analog scale (VAS) were collected at different time points. Tumor recurrence in the vertebrae after PV was analyzed using Kaplan–Meier curves. Results: The STWZ approach was successful from T1 to L5 without severe complications. Cement filling was satisfactory in 47/54 (87.0%) and 25/57 (43.9%) vertebrae in groups A and B, respectively (v< 0.001). Cement leakage was not significantly different between groups A and B (p= 1.000). Mean VAS score ± SD before and 1 week and 1, 3, 6, 9, and 12 months after PV were 7.6 ± 1.8, 4.2 ± 2.0, 2.7 ± 1.9, 1.9 ± 1.5, 1.7 ± 1.4, 1.7 ± 1.1, and 1.6 ± 1.3, respectively, in group A and 7.2 ± 1.7, 4.0 ± 1.3, 3.4 ± 1.6, 2.4 ± 1.2, 1.8 ± 1.0, 1.4 ± 0.5, and 1.7 ± 0.9, respectively, in group B. Kaplan–Meier analysis showed a lower tumor recurrence rate in group A than in group B (p = 0.001). Conclusion The STWZ approach may represent a new, safe, alternative/auxiliary approach to target the posterior part of the vertebral body in the PV for spinal metastases.

OBJECTIVE: To explore the changes in bone height of the maxillary sinus floor at different sinus ridge heights after transcrestal sinus floor elevation (tSFE) with the simultaneous implantation of short implants. METHODS: A total of 74 Bicon short implants were implanted into 37 patients during the same period of maxillary sinus elevation. The residual bone height (RBH)<4 mm group has 43 sites, and the RBH≥4 mm group has 31 sites. After 5 years of follow-up observation, the implant survival rate and the change in bone height achieved in the maxillary sinus over time were measured and analyzed via clinical examination and X-ray imaging. RESULTS: In the 74 implantation sites, the elevation height of the sinus floor was (6.64±1.32) mm and the bone height of the sinus floor was (3.35±1.29) mm 5 years after loading. No statistical difference was observed in the bone resorption of the implant neck between the RBH<4 mm and RBH≥4 mm groups. Meanwhile, a statistical difference was noted in the bone height obtained in the maxillary sinus between the two groups. CONCLUSIONS When RBH in the maxillary posterior tooth area was <4 mm, the simultaneous implantation of Bicon short implants with tSFE can achieve a high implant survival rate and bone gain in the maxillary sinus, but does not increase the absorption of the alveolar ridge bone.

ObjectiveMicroRNAs (miRNA) play an important role in the development and regression of osteoporosis. This study aims to screen for miRNAs and genes closely related to osteoporosis, and to complete the construction of a miRNA-mRNA regulatory network of osteoporosis.MethodsThe gene chip expression profile of osteoporosis was obtained through the GEO database, and the differentially expressed genes (DEGs) and miRNAs were analyzed and screened via GEO2R. We used volcanic maps to display differential genes and miRNAs, and completed the GO and KEGG pathway analysis through the David online database. The String online database is used to complete PPI protein network analysis. The TargetScan, miRTarBase and miRDB were used to predict the targeted genes. Finally, the PPI and miRNA-mRNA regulatory networks were visualized by Cytoscape software.ResultsWe obtained 15 differential miRNAs and 174 differentially expressed genes through screening. The GO enrichment analysis mainly focused on drug response, angiogenesis, ion transport, regulation of small GTPase mediated signal ransduction, adaptive immune response, etc. NF-κB signaling pathway and HIF-1 signal were obtained through KEGG enrichment analysis. We obtained 10 hub genes through the cytohubba plug-in. We also obtained 3065 targeted genes by processing of seven miRNAs, and then intersected them with 174 DEGs to obtain 44 intersection genes. Finally, we successfully constructed a regulation map of miRNA-mRNA network. The miR-194-5p is significantly up-regulated in osteoporosis.ConclusionThe miR-194-5p might play an important role in osteoporosis by regulating its target gene CDH2, which provides candidate targets for the diagnosis and treatment of osteoporosis.

Objective:To investigate the availability, prices and affordability of essential medicines in pediatric population across China, in the hope of improving rational use of medicines.Methods:A multicenter cross-sectional survey of medicine prices, availability and affordability was conducted in 17 provinces, municipalities and autonomous region across east, south-central part, west and north of China. Data on 42 medicines used in pediatric population, both original and generic, were collected in 55 public hospitals from May 26 to June 2, 2017. Availability was expressed as the percentage of hospitals with stock of the target medicine on the day of data collection,and median price ratio (MPR) was the ratio of price upon investigation to international reference. Based on national minimum daily wage, affordability represents the number of working days needed to earn the expense which covers a standard course using the target medicine. Statistical software SPSS 13.0 was applied for descriptive analysis of availability, MPR and affordability.Results:Mean Availability of original and generic medicine was 33% and 32%, with median MPR being 5.43 and 1.55. Among the 19 medicines with price information for both original and generic product, the median MPR was 7.73 and 2.04 respectively. Regarding the five medicines used to treat four common pediatric diseases (pneumonia,peptic ulcer, congenital hypothyroidism, refractory nephrotic syndrome), the affordability was 0.63 (0.16-6.17) d for generic medicine, and 1.03 (0.16-11.53) d for its original counterpart.Conclusions:The availability to both original and generic products of the 42 medicines used in pediatric population was low in China. The prices of generic medicines seem to be lower and affordability higher than those of original medicines. There is an urgent need to improve the availability and affordability of pediatric medicines.

Objective To understand the epidemiological features and changing patterns of intestinal parasitic diseases in Jiangxi Province from 1989 to 2014, so as to provide scientific evidence for formulating the preventive and control strategy for intestinal parasitic diseases. Methods The data regarding the status of intestinal parasitic diseases in Jiangxi Province were captured from the 1989 national survey on the distribution of human parasites in China and the 2014 national survey on major human parasitic diseases in China, and the status of human intestinal parasite infections was compared between the two surveys in Jiangxi Province. Results The prevalence rate of human intestinal parasite infections was 79.59% and 9.64% in Jiangxi Province in 1989 and 2014, with a decline rate of 87.89% during the 25-year period (χ² = 30 870.5, P < 0.01). There were 24 and 20 species of human intestinal parasites detected in Jiangxi Province in 1989 and 2014, respectively, with totally 26 species detected during the two surveys. In Jiangxi Province, the 3 most highly prevalent human intestinal parasites included Ascaris lumbricoides (71.06%), hookworm (17.61%) and Enterobius vermicularis (17.59%) in 1989, and E. vermicularis (13.73%), hookworm (4.66%), whipworm (0.95%) in 2014. A higher rate of human intestinal parasite infections was found in females than in males in both surveys in Jiangxi Province (P < 0.01), and the prevalence of human intestinal parasite infections reduced by 82.50% to 95.31% in different age groups in Jiangsu Province during the 25-year period. Conclusions The prevalence of human intestinal parasite infections shows a remarkable decline tendency in Jiangxi Province, and soil-transmitted nematodes remain the main species of human intestinal parasites in Jiangxi Province.

Objective Changes in the number and function of myeloid-derived suppressor cells (MDSC) were reported in clinical and experimental Sjögren’s syndrome (SS), whereas the underlying mechanisms of MDSCs in SS remain to be elucidated. This study was to observe the changes in the pathologic structure and function of the submandibular gland and salivary flow in SS mice after adoptive transfer or deletion of MDSCs and explore the action mechanisms of MDSCs. Methods Ten 4-week-old non-obese diabetic (NOD) mice (without SS-like symptoms) received adoptive transfer of purified MDSCs at 1×10⁶ per mouse (the MDSC group, n = 5) or injection of PBS (the PBS group, n = 5). Another ten 10-week-old NOD mice were injected intraperitoneally with anti-Gr1 antibodies (the anti-Gr1 group, n = 5) or commensurable Rat IgG2b isotype antibodies (the Rat IgG2b group, n = 5). At 2 weeks after treatment, we determined the salivary flow rate, examined lymphocytic infiltration in the submandibular glands, and counted the MDSCs on Th2 cells in different groups of the mice. Results Compared with the PBS group, the NOD mice of the MDSC group showed significantly reduced Th2 cells in the peripheral blood ([0.67 ± 0.13] % vs [0.16 ± 0.07] %, P < 0.05) and spleen ([0.80 ± 0.13] % vs [0.37 ± 0.04] %, P < 0.05) and salivary flow ([78.70 ± 6.80] vs [33.85 ± 11.25] µL, P < 0.05), but increased numbers of MDSCs in the peripheral blood ([1.54 ± 0.14] vs [5.47 ± 1.54] ×10⁵, P < 0.05) and spleen ([1.09 ± 0.23] vs [4.50 ± 1.04] ×10⁵, P < 0.05). In comparison with the Rat IgG2b group, the animals of the anti-Gr1 group exhibited remarkably decreased Th2 cells in the peripheral blood ([0.55 ±0.09] % vs [0.92 ± 0.10] %, P < 0.05) and spleen ([0.63 ± 0.08] % vs [1.10 ± 0.06] %, P < 0.05) and salivary flow ([56.48 ± 14.18] vs [121.20 ± 10.34] µL, P < 0.05), as well as decreased numbers of MDSCs in the peripheral blood ([1.53 ± 0.12] vs [0.35±0.16] ×10⁵, P < 0.05) and spleen ([2.53 ± 1.10] vs [0.91±0.07] ×10⁵, P < 0.05). The adoptive transfer of MDSCs aggravated while the injection of anti-Gr1 antibodies attenuated lymphocytic infiltration in the submandibular gland of the mice. Conclusion MDSCs participate in the pathogenesis Sjögren’s syndrome by suppressing the response of Th2 cells, which suggests that increasing the response of Th2 cells by inhibiting MDSCs could be a novel target for the treatment of Sjögren’s syndrome.

Objective To investigate the prevalence of major parasitic diseases and related knowledge,attitude and practice among rural residents in Liyang City,so as to provide the evidence for formulating appropriate preventive strategies and mea-sures.Methods Three villages were selected from three towns as survey sites,and the residents who were above three years old and had been in the village for over six months were investigated.The Kato-Katz technique was applied to detect intestinal para-site eggs in residents'feces,and the cellophane anal swab was used to detect Enterobius vermicularis eggs among children aged 3-6 years. The iodine liquid smear and saline smear methods were used to examine intestinal protozoa cysts or trophozoites. Hookworm species were identified by the tube filter paper culture method.A structured questionnaire was used to collect the in-formation on residents'knowledge,attitude and practice of the prevention and control of major parasitic diseases.Results To-tally 759 residents were investigated and tested at the three rural survey sites,and only 2 cases were detected of parasitic infec-tion and the total infection rate was 0.26%.Both cases were mild infections without mixed infection.The total awareness rate of knowledge on ascariasis,trichuriasis and ancylostomiasis was 37.9%,while the awareness rate of knowledge on clonorchiasis was 13.8%.The age and educational level were important factors of the knowledge on prevention and control of parasitic diseases among the residents.The formation rates of washing hands before meal and after using the toilet,and never drinking unboiled wa-ter were 83.8% and 92.1%,respectively. Totally 11.6% of the residents usually ate raw or half-cooked freshwater fishes and shrimps,and 53.0% had not the behavior to prepare raw and cooked food using the different chopping boards.The proportions of residents using fresh feces as manure and working in the field with bare feet were 13.8% and 22.8% respectively.The proportions of residents who thought they could,could not,or were not sure to change the risk behaviors and habits of parasitic infections were 40.2%,28.5% and 31.4%,respectively.Conclusions The infection rate of major parasitic diseases among the rural resi-dents in Liyang City is low,and the awareness rate of knowledge on preventing parasitic diseases is also low. Therefore,the health education on the prevention and control of parasitic diseases should be strengthened to guide them to develop good hy-giene,diet and farming habits.The environmental sanitation should be continuously improved to block the endemic of parasitic infection.
