Diabetic nephropathy （DN） is one of the most common and severe microvascular complications of diabetes， with a complex pathogenesis involving immune inflammatory responses， oxidative stress， apoptosis， glomerulosclerosis， renal interstitial fibrosis， and other pathological processes. In recent years， numerous animal or cell model experiments have revealed that the transforming growth factor-β （TGF-β）/mothers against decapentaplegic homolog （Smad）， phosphoinositide 3-kinase （PI3K）/ protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， mitogen-activated protein kinase （MAPK）， AMP-activated protein kinase （AMPK）， nuclear factor-κB （NF-κB）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， neurogenic locus notch homolog protein （Notch）， nuclear factor E₂-related factor 2 （Nrf2）， secretory glycoprotein （Wnt）/β-catenin， and other classical signaling pathways play important roles in the occurrence and development of DN. Traditional Chinese medicines， as natural drugs， possess characteristics such as multiple components， multiple targets， and few adverse reactions， demonstrating unique advantages in regulating the aforementioned signaling pathways and improving renal pathological changes. This review summarized recent research progress on the intervention of DN through the regulation of the aforementioned signaling pathways by single compounds and formulas of traditional Chinese medicine， focusing on their mechanisms of action in regulating immune inflammatory responses， inhibiting renal fibrosis， oxidative stress， improving metabolic disorders， and other aspects. The aim is to provide theoretical references for a deeper understanding of the modern pharmacological basis and clinical application of traditional Chinese medicine in the treatment of DN.

Objective:To investigate the efficacy and safety of lenvatinib plus drug-eluting bead transarterial chemoembolization (DEB-TACE) and FOLFOX-based hepatic arterial infusion chemotherapy (Len+DEB-TACE+HAIC) versus lenvatinib plus DEB-TACE (Len+DEB-TACE) for hepatocellular carcinoma (HCC) larger than 7 cm with portal vein tumor thrombosis (PVTT).Methods:The data from patients diagnosed with HCC (>7 cm) and PVTT who received either Len+DEB-TACE+HAIC ( n=99) or Len+DEB-TACE ( n=102) between July 2019 and June 2021 at six institutions in China were collected and retrospectively analyzed. Tumor responses were evaluated based on modified Response Evaluation Criteria in Solid Tumors. Objective response rate (ORR), disease control rate (DCR), time to progression (TTP), overall survival (OS), and treatment-related adverse event (TRAE) were compared between the two groups by propensity score matching. Subgroup analyses were performed for TTP and OS. Results:After propensity score matching, 83 pairs of patients were included in the study cohorts. The ORR for the Len+DEB-TACE+HAIC group and the Len+DEB-TACE group was 66.3% and 38.6% ( χ2=12.78, P<0.001), respectively. The DCR for the Len+DEB-TACE+HAIC group and the Len+DEB-TACE group was 91.6% and 79.5% ( χ2=4.87, P=0.027), respectively. The median TTP and median OS for the Len+DEB-TACE+HAIC group were significantly longer than those for the Len+DEB-TACE group (TTP, 10.1 months vs. 6.1 months, χ2=35.28, P<0.001; OS, 17.3 months vs. 12.9 months, χ2=16.84, P<0.001). The incidence of ≥grade 3 TRAEs was 38.6% in the Len+DEB-TACE+HAIC group and 33.7% in the Len+DEB-TACE group ( χ2=0.42, P=0.518). Conclusion:Compared with Len+DEB-TACE, Len+DEB-TACE+HAIC led to improved tumor response, TTP and OS with an acceptable safety profile in patients with large HCC and PVTT.

As an important complementary form of decoction pieces of traditional Chinese medicine（TCM）， TCM dispensing granules has the advantages of being free of decoction， easy to take， easy to carry and easy to be dispensed， which greatly improves the capacity of emergency services of TCM and is more in line with the needs of modern society. With the end of the pilot project of TCM dispensing granules， the market has been fully liberalized， the competition has been intensified， and it is in the transition period of switching between the new standard and the old one， and there are some problems such as the shortage of varieties， the change of specifications and the difference of quality， and the production enterprises are facing new opportunities and challenges. Based on this， the authors intend to systematically sort out the policies and regulations， enterprise layout and standard formulation since the pilot of TCM dispensing granules. In view of the problems in the post-pilot stage and from the perspective of survival and development of enterprises， it is suggested that enterprises should establish a quality control system for the whole industry chain of TCM dispensing granules to reduce process costs and increase enterprise competitiveness， further increase the investment in scientific research， overcome the key technical problems of difficult varieties， actively and orderly promote the research of national standards， in order to ensure the integrity of clinical formula varieties， and establish and improve the efficacy evaluation mechanism of TCM dispensing granules， build a consistency evaluation system between TCM dispensing granules and decoction pieces. Government departments should strengthen the guidance， fully mobilize the enthusiasm of scientific research institutions， enterprises and hospitals， and explore the establishment of "government-industry-study-research-application" mode to promote the development of TCM dispensing granule industry.

Background Neck-shoulder pain is one of the most common discomfort symptoms among nursing staff, mostly caused by a heavy workload, restricted workstation, and prolonged poor posture. Objective To investigate the prevalence of neck-shoulder pain among nursing staff in tertiary general hospitals in Hunan Province, and to analyze workload-related risk factors. Methods From October to December 2018, a multi-stage stratified randomized cluster sampling method was adopted to select a total of 1 200 nursing staff who met the inclusion andexclusion criteria in six tertiary general hospitals from five geographic subdivisions of Hunan Province were selected. A self-designed questionnaire was used to collect demographic characteristics, and past 1-month prevalence of neck-shoulder pain, a neck disability index (NDI) was used to assess the impact of neck pain on daily life, and functional disability was graded by the index of impaired neck function; a self-designed questionnaire was adopted to evaluate potential workload-related risk factors (working time, postural load, and force load) of neck-shoulder pain after a Delphi expert consultation. A total of 1 161 valid questionnaires were returned, and χ^２test and logistic regression model were used to screen the potential risk factors for neck-shoulder pain. Results The prevalence rate of neck-shoulder pain in the past 1 month was 87.5% (1 016/1 161) and varied by different characteristics of the nursing staff, ranging from 76.9% to 91.2%. The scores of the 10 items of the NDI ranged from 0 to 5, but most of them were 0, 1, and 2; of the 10 items, neck pain had the greatest impact on sleep (1.30±1.21) and the least impact on self-care behaviors (0.35±0.65). The index of impaired neck function showed that the majority (65.4%) of nurses had mild cervical spine dysfunction and 30.1% had moderate cervical spine dysfunction. The univariate analysis results revealed that 24 out of the 31 workload-related risk factors had significant differences, and further multiple analysis results showed that three variables entered the logistic regression model. Under the same conditions, nurses with ≥5 h of cumulative head-down tasks per shift had 3.03 times higher neck-shoulder pain risks compared with those with ＜1 h. Compared with “occasionally or never”, nurses who “sometimes” and “often” tilted their necks back and maintained this posture for a long time showed 2.36 and 2.94 times higher risks for neck-shoulder pain respectively. The nurses who reported “sometimes” and “often” having difficulty using their force at work due to unnatural posture had 2.78 times and 7.08 times higher neck-shoulder pain risks than those who “occasionally or never” respectively. Conclusion The reported rate of neck-shoulder pain among nurses in tertiary general hospitals in Hunan Province is high, but most of them are mild dysfunction. Working hours and posture load may affect the risk of neck-shoulder pain.

Objective:To study the patterns of tocilizumab (TCZ) use, its efficacy and safety in patients with rheumatoid arthritis (RA) in routine clinical practice.Methods:A total of 407 patients with RA were enrolled from 23 centers and treated with TCZ within 8 weeks prior to the enrollment visit, and were followed for 6-month. The patterns of TCZ treatment at 6 months, the effectiveness and safety outcomes were recorded. Statistical analysis was performed using SAS version 9.4.Results:A total of 396 patients were included for analysis, in which 330 (83.3%) patients received TCZ combined with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), and 16.7%(66/396) received TCZ monotherapy. At baseline, TCZ was initiated in 56.6%(224/396) and 9.6%(38/396) of patients after failure of DMARDs and other biological agents (bDMARDs) respectively. During the 6-month follow-up period, the mean frequency of TCZ administration was (3.7±1.6), the mean TCZ dosage was (7.4±1.2) mg/kg, and the mean interval between doses was (40±13) days. 120(25.8%) patients were on TCZ treatment at the end of the study. Improvements in disease activity, systemic symptoms and patient report outcomes were observed at the end of the study. 22.7%(90/396) patients experienced at least one treatment related adverse event, and 8 patients experienced at least one serious adverse event.Conclusion:This study demonstrates that TCZ treatment is effective in patients with RA when being treated for 6 months with an acceptable safety profile. The duration of TCZ treatment needs to be extended.

Objective To explore the effect of the Internet technology′s application on the hand hygiene compliance of medical staff. Methods Establishing Internet+hand hygiene management model to implement Internet based hand hygiene supervisory and reminding, Internet based hand hygiene publicity and education, and Internet based hand hygiene feedback and communication. This model was applied in Guangdong Provincial Dermatology Hospital to intervene the hand hygiene related activities. Before and after the intervention, the hand hygiene compliance of medical staff in the trial hospital was observed with WHO hand hygiene monitoring table by directly manual observation. Thereafter, the changes of hand hygiene compliance before and after the intervention were compared based on the statistical analysis of test results. Results With the application of Internet+hand hygiene management model, the hand hygiene compliance of medical staff increased from 41.75% (324/776) before the intervention to 72.14% (554/768) after the intervention, and the difference was statistically significant (χ2=145.264, P<0.01). The hand hygiene compliance of both doctors and nurses was significantly increased (doctors: χ2=94.784, P<0.01;nurses:χ2=58.798, P<0.01). In all the five indications, i.e., before patient care, before an aseptic task, after exposure to blood/body fluids, after patient care, and after environmental contact, the hand hygiene compliance was 35.42%(68/192), 63.33%(38/60), 84.38%(54/64), 44.83%(130/290), and 20.00%(34/170) respectively before the intervention;it was 65.38%(102/156), 83.33%(120/144), 95.45%(105/110), 68.52%(148/216), and 55.63%(79/142) after the intervention; and the difference before and after the intervention was statistically significant (χ2=6.305-42.529;P<0.01 or 0.05). Most of the medical staff of the trial department supported this model. Conclusions Internet+ hand hygiene management model could significantly improve the hand hygiene compliance of medical staff and were very popular. And, the model is worth of application in more hospitals.
