ABSTRACT

ObjectiveThis study aims to understand the recognition of practitioners in traditional Chinese medicine (TCM) hospitals on hospital-based health technology assessment (HB-HTA), assessment needs, challenges, and suggestions, so as to provide references for the future work. MethodThe convenient sampling method was adopted to survey the relevant practitioners in TCM hospitals. The questionnaire included 39 questions in 4 dimensions and was distributed through the online platform Weijuanxing. ResultA total of 244 questionnaires were recovered, and the obtained data were analyzed in SPSS. The results showed that 137 practitioners were very familiar with HB-HTA and there was no significant difference in the recognition of practitioners in different occupations (F=0.251; P=0.778). The practitioners in Hong Kong, Macao, and Taiwan had lower recognition than those in other regions. In terms of the assessment needs, 127 practitioners believed that it was very necessary to carry out HB-HTA in TCM hospitals in the future. Chinese patent medicines/Chinese herbal medicine decoction pieces (5.91) and TCM appropriate technology (5.57) had higher assessment priority scores. The assessment needs were high for the effectiveness (235 practitioners) and safety (224 practitioners) of health technology. The lack of specialized organization and standardized evaluation process system and the shortage of talents were considered to be the major challenges for the future development in this field. ConclusionThe stakeholders carrying out the health technology assessment in TCM hospitals had certain awareness of HB-HTA. Most practitioners believed that it was necessary to carry out HB-HTA in TCM hospitals in the future, while the work might face challenges such as the lack of organizations and system and the shortage of talents, which requires policy support.

ABSTRACT

Da Qinjiaotang is a common classical prescription for the treatment of stroke. It originates from Collection of Writings on the Mechanism of Disease, Suitability of Qi, and the Safeguarding of Life as Discussed in the Basic Questions (《素问病机气宜保命集》) by physician LIU Wansu, and is composed of Gentianae Macrophyllae Radix, Glycyrrhizae Radix et Rhizoma, Chuanxiong Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, Asari Radix et Rhizoma, Notopterygii Rhizoma et Radix, Saposhnikoviae Radix, Scutellariae Radix, Gypsum Fibrosum, Angelicae Dahuricae Radix, Atractylodis Macrocephalae Rhizoma, Rehmanniae Radix, Rehmanniae Radix Praeparata, Poria, and Angelicae Pubescentis Radix. Doctors of all dynasties have disputed the composition principle of the prescription and argued whether its treatment of stroke belongs to the theory of "internal wind" or "external wind". Through collating and analyzing ancient and modern literature related to the indications of Da Qinjiaotang, this paper was dedicated to the origin of syndrome differentiation and treatment of Da Qinjiaotang. According to LIU Wansu's original works, Da Qinjiaotang is a prescription for the treatment of "internal wind", and in the prescription, wind medicinal herbs such as Gentianae Macrophyllae Radix, Notopterygii Rhizoma et Radix and Angelicae Pubescentis Radix removes stagnation, clears sweat pore, and makes qi and blood channels flow smoothly. However, later generations, affected by the idea of "external wind", believe that this prescription is used for the treatment of "external wind". Ancient physicians gradually supplemented the symptoms of stroke, such as wry eye and mouth, hemibody pain and limb numbness, which were treated by Da Qinjiaotang, and Da Qinjiaotang was also applied to the treatment of other diseases, such as tendon dryness, convulsion and arthralgia. Modern doctors still explain the disease pathogenesis from the theory of "external wind" as deficiency in channels and collaterals and the entry of pathogenic wind, and the prescription has the effect of dispersing wind, clearing heat and nourishing and activating blood. In clinical practice, Da Qinjiaotang is mainly used to treat cerebrovascular diseases and peripheral facial paralysis in nervous system diseases, gouty arthritis and rheumatic arthritis in the rheumatic immune system and skin diseases. The above findings facilitate the research and development of Da Qinjiaotang.

ABSTRACT

ObjectiveTo explore the effect of Baitouweng Tang (BTWT) on the apoptosis of human colorectal cancer HCT116 cells and decipher the underlying mechanism based on the Hedgehog (Hh) signaling pathway. MethodHCT116 cells were treated with BTWT (25, 50, 100, 200, 500, 750, and 1 000 mg·L-1) for 24 h, and then the cell proliferation was detected by methyl thiazolyl tetrazolium (MTT) colorimetry. Five groups were designed for the treatment of HCT116 cells, including a blank control group, BTWT groups (125, 250, and 500 mg·L-1), and a positive control (5-fluorouracil, 5-FU, 40 mmol·L-1) group. The cell morphology was observed under an inverted microscope. The migration of the cells was detected by scratch test, and the apoptosis by Hoechest 33324/propidium iodide (PI) staining and flow cytometry. Western blot was employed to determine the protein levels of sonic hedgehog (SHh), GLI family zinc finger protein 1 (Gli1), smoothened (Smo), suppressor of fused (SuFu), cellular-myelocytomatosis viral oncogene (c-Myc), and the apoptosis-related proteins B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax). The quantitative real-time reverse transcription PCR (Real-time PCR) was employed to determine the mRNA levels of Bax, Bcl-2, SHh, Gli1, Smo, SuFu, and c-Myc. ResultCompared with the blank control group, BTWT changed the cell morphology (making the cell become round with dense nucleus), inhibited the proliferation of HCT116 cells in a dose-dependent manner, decreased the ability of migration (P<0.05, P<0.01), and increased apoptotic cells. Compared with the blank control group, BTWT (500 mg·L-1) treatment for 24 h up-regulated the protein and mRNA levels of Bax (P<0.05, P<0.01) and down-regulated the protein and mRNA levels of Bcl-2 in HCT116 cells (P<0.05, P<0.01). Moreover, the treatment down-regulated the mRNA and protein levels of SHh, Gli1, Smo, and c-Myc (P<0.05, P<0.01) and up-regulated the mRNA and protein levels of SuFu (P<0.05, P<0.01). ConclusionBTWT inhibited the proliferation and migration and induced the apoptosis of colorectal cancer HCT116 cells by down-regulating the Hh signaling pathway.

ABSTRACT

This paper reports the clinical pharmacist participated in the diagnosis and treatment of a patient with acanthoma caused by nivolumab. This patient developed acanthoma 2 weeks after medication, involving scalp, neck, trunk, back of hand, sole of foot and other parts, with moderate pruritus. The clinical pharmacist determined it as “yes” according to the causality evaluation method of adverse reactions. After reviewing the literature, clinical pharmacists found that acanthoma caused by immune checkpoint inhibitors was more commonly seen in male elderly patients with malignant melanoma, and mainly involved the trunk, extremities and hands. Under the general principle of considering the effectiveness, safety, economy and accessibility of therapeutic drugs, the clinical pharmacist finally decided to give the patient a comprehensive treatment scheme of Halometasone cream for external use + oral administration of Retinoic acid capsules + oral administration of Ebastine tablets after discussion with the doctor, with maximum respect for the patient’s wishes,and continued to use navulizumab for immunotherapy. At the same time, pharmaceutical care and psychological counseling were conducted by clinical pharmacist. Finally, the patient successfully completed the treatment, and the acanthoma gradually subsided after the end of navulizumab treatment. The diagnosis and treatment process of this patient indicated that the participation of clinical pharmacists is helpful to improve the continuity and safety of immunotherapy.

ABSTRACT

Objective:To observe the effect and mechanism of Tanhuo Prescription on regulating the activation of M1 microglia and alleviating brain tissue injury in rats with cerebral ischemia.Methods:Male SD rats were divided into sham-operation group, model group, Tanhuo Prescription high-(3.68 g/kg), medium-(1.84 g/kg), low-dosage(0.92 g/kg) groups, and ginaton group (0.06 g/kg) using random number table method. Except for the sham-operation group, the other groups established cerebral ischemia rat models using the middle cerebral artery occlusion method. The balance beam walking test was used to evaluate the symptoms of neurological deficit. MRI-T2 mapping was used to measure the damage to brain tissue. LFB staining was used to observe the damage to nerve fibers. HE staining was used to observe the damage to nerve cell, and Iba-1 and CD16/Iba-1 immunofluorescence staining were used to observe the condition of microglial activation.Results:Compared with the model group, the scores of balance beam walking ability of rats in Tanhuo Prescription high-dose group and ginaton group at 24 h, 48 h and 72 h after ischemia were significantly improved ( P<0.05, P<0.01). The scores of balance beam walking ability of rats in Tanhuo Prescription low- and medium- dose groups at 72 h after ischemia were improved ( P<0.01). Compared with the model group, the T2 values of the cortex and striatum around the infarct of rats in Tanhuo Prescription high-dose group and ginaton group were significantly reduced ( P<0.05, P<0.01), and the T2 values of the striatum around the infarct of rats in Tanhuo Prescription low- and medium- dose groups were significantly reduced ( P<0.05). Compared with the model group, the LFB IOD of the cortex, striatum and outer capsule around the infarct decreased in the Tanhuo Prescription high-,low-dose group and ginaton group ( P<0.01). The LFB IOD of striatum around infarct decreased in medium- dose Tanhuo Prescription group ( P<0.01). Compared with the model group, the pathological injury degree of the striatum around the infarct of rats in Tanhuo Prescription low- ,medium-, and high-dose groups decreased, and the cell density decreased ( P<0.05, P<0.01). The density of the cortical and striatum cells around the infarct of rats in ginaton group increased ( P<0.01, P<0.05). Compared with the model group, the number of Iba-1 and CD16/Iba-1 positive cells in the cortex and striatum around the infarct decreased in Tanhuo Prescription medium-, high-dose and ginaton groups ( P<0.01). The number of CD16/Iba-1 positive cells in the cortex and striatum around the infarct of rats in Tanhuo Prescription low-dose group decreased ( P<0.01), and the number of Iba-1 positive cells in the striatum around the infarct of rats in Tanhuo Prescription low-dose group decreased ( P<0.01). Conclusion:Tanhuo Prescription can improve the symptoms of neurological deficits in rats with cerebral ischemia, reduce the neuropathological damage in the cerebral area around ischemic infarction, and inhibit the activation of M1 microglia.

ABSTRACT

Objective: T lymphocyte exhaustion is an important component of immune dysfunction. Therefore, exploring peripheral blood-exhausted T lymphocyte features in patients with hepatitis B virus-related acute-on-chronic liver failure may provide potential therapeutic target molecules for ACLF immune dysfunction. Methods: Six cases with HBV-ACLF and three healthy controls were selected for T-cell heterogeneity detection using the single-cell RNA sequencing method. In addition, exhausted T lymphocyte subpopulations were screened to analyze their gene expression features, and their developmental trajectories quasi-timing. An independent sample t-test was used to compare the samples between the two groups. Results: Peripheral blood T lymphocytes in HBV-ACLF patients had different differentiation trajectories with different features distinct into eight subpopulations. Among them, the CD4(+)TIGIT(+) subsets (P = 0.007) and CD8(+)LAG3(+) (P = 0.010) subsets with highly exhausted genes were significantly higher than those in healthy controls. Quasi-time analysis showed that CD4(+)TIGIT(+) and CD8(+)LAG3(+) subsets appeared in the late stage of T lymphocyte differentiation, suggesting the transition of T lymphocyte from naïve-effector-exhausted during ACLF pathogenesis. Conclusion: There is heterogeneity in peripheral blood T lymphocyte differentiation in patients with HBV-ACLF, and the number of exhausted T cells featured by CD4(+)TIGIT(+)T cell and CD8(+)LAG3(+) T cell subsets increases significantly, suggesting that T lymphocyte immune exhaustion is involved in the immune dysfunction of HBV-ACLF, thereby identifying potential effective target molecules for improving ACLF patients' immune function.

ABSTRACT

Objective: To evaluate HPV prevalence and type distribution in Chinese juvenile-onset recurrent respiratory papillomatosis (JoRRP) patients. Methods: We searched China National Knowledge Infrastructure, Wanfang data, China Biology Medicine disc, PubMed, Embase, and the Cochrane Library for studies assessing HPV infection of Chinese JoRRP patients up to 1 October, 2022. Two authors independently performed literature selection, data extraction, and quality assessment. HPV prevalence and HPV type-specific prevalence were pooled using a random effects model after Freeman-Tukey double arcsine transformation. All analyses were performed with R 4.1.3 software. Results: Nineteen publications investigating HPV infection of JoRRP patients were included in the final analyses. Of these, 16 studies reported HPV prevalence with a sample size of 1 528 patients, and 11 studies reported HPV6 prevalence and HPV11 prevalence with a sample size of 611 patients. All studies were graded as medium quality. In Chinese JoRRP patients, the synthesized HPV prevalence was 92.0% (95%CI:86.0%-96.6%, I2=87%), HPV6 prevalence was 42.4% (95%CI:34.9%-50.1%, I2=61%), and HPV11 prevalence was 72.3% (95%CI:59.0%-83.9%, I2=87%). All the pooled prevalence persisted in subgroup analyses stratified by publication year, sample size, and specimen type (P>0.05). There was no evidence of publication bias. In Chinese JoRRP patients, HPV16, 18, 31, 33, 52, and 58 prevalence was very low. Conclusions: Our findings suggested high HPV prevalence in Chinese JoRRP patients, and the most common HPV types were HPV6 and HPV11.

ABSTRACT

In China, the current standard for cosmetic adverse reactions related skin disease (GB/T 17149.1-1997) was jointly issued by the Ministry of Health and the State Bureau of Technical Supervision in 1997, cosmetic-allergic adverse reactions include allergic contact dermatitis and photo-allergic contact dermatitis according to this standard. The increasing use and changes in cosmetic ingredients or formula lead to a significant increase for the incidence of adverse reactions as the cosmetics industry is developing rapidly in the last 20 years. In the meantime, the clinical manifestations have become more diverse. In recent years, there have been many reports on the special manifestations for cosmetic allergy and allergen test, which provide a reference for the subsequent improvement of the diagnosis and prevention.

ABSTRACT

Objective: To investigate the effects of human umbilical cord mesenchymal stem cells (hUCMSCs) combined with autologous Meek microskin transplantation on patients with extensive burns. Methods: The prospective self-controlled study was conducted. From May 2019 to June 2022, 16 patients with extensive burns admitted to the 990th Hospital of PLA Joint Logistics Support Force met the inclusion criteria, while 3 patients were excluded according to the exclusion criteria, and 13 patients were finally selected, including 10 males and 3 females, aged 24-61 (42±13) years. A total of 20 trial areas (40 wounds, with area of 10 cm×10 cm in each wound) were selected. Two adjacent wounds in each trial area were divided into hUCMSC+gel group applied with hyaluronic acid gel containing hUCMSCs and gel only group applied with hyaluronic acid gel only according to the random number table, with 20 wounds in each group. Afterwards the wounds in two groups were transplanted with autologous Meek microskin grafts with an extension ratio of 1∶6. In 2, 3, and 4 weeks post operation, the wound healing was observed, the wound healing rate was calculated, and the wound healing time was recorded. The specimen of wound secretion was collected for microorganism culture if there was purulent secretion on the wound post operation. In 3, 6, and 12 months post operation, the scar hyperplasia in wound was assessed using the Vancouver scar scale (VSS). In 3 months post operation, the wound tissue was collected for hematoxylin-eosin (HE) staining to observe the morphological changes and for immunohistochemical staining to observe the positive expressions of Ki67 and vimentin and to count the number of positive cells. Data were statistically analyzed with paired samples t test and Bonferronni correction. Results: In 2, 3, and 4 weeks post operation, the wound healing rates in hUCMSC+gel group were (80±11)%, (84±12)%, and (92±9)%, respectively, which were significantly higher than (67±18)%, (74±21)%, and (84±16)% in gel only group (with t values of 4.01, 3.52, and 3.66, respectively, P<0.05). The wound healing time in hUCMSC+gel group was (31±11) d, which was significantly shorter than (36±13) d in gel only group (t=-3.68, P<0.05). The microbiological culture of the postoperative wound secretion specimens from the adjacent wounds in 2 groups was identical, with negative results in 4 trial areas and positive results in 16 trial areas. In 3, 6, and 12 months post operation, the VSS scores of wounds in gel only group were 7.8±1.9, 6.7±2.1, and 5.4±1.6, which were significantly higher than 6.8±1.8, 5.6±1.6, and 4.0±1.4 in hUCMSC+gel group, respectively (with t values of -4.79, -4.37, and -5.47, respectively, P<0.05). In 3 months post operation, HE staining showed an increase in epidermal layer thickness and epidermal crest in wound in hUCMSC+gel group compared with those in gel only group, and immunohistochemical staining showed a significant increase in the number of Ki67 positive cells in wound in hUCMSC+gel group compared with those in gel only group (t=4.39, P<0.05), with no statistically significant difference in the number of vimentin positive cells in wound between the 2 groups (P>0.05). Conclusions: The application of hyaluronic acid gel containing hUCMSCs to the wound is simple to perform and is therefore a preferable route. Topical application of hUCMSCs can promote healing of the autologous Meek microskin grafted area in patients with extensive burns, shorten wound healing time, and alleviate scar hyperplasia. The above effects may be related to the increased epidermal thickness and epidermal crest, and active cell proliferation.

ABSTRACT

Huoluo Xiaoling Dan is a classical prescription commonly used for blood circulation and pain relief in clinic with obvious effects. To make it directly treat lesion and improve the effect, this research optimized the preparation process of Huoluo Xiaoling gel paste and further evaluated its in vitro transdermal absorption performance, so as to provide a scientific basis for its development and utilization. Using primary viscosity, holding viscosity, and sensory score as evaluation indexes, the matrix amount of gel paste was determined by the single factor test and Box-Behnken response surface method. The ultra-performance liquid chromatography(UPLC) method was established to determine the content of eight active ingredients, including Danshensu, ferulic acid, salvianolic acid B, salvianolic acid A, ligustilide, tanshinone Ⅱ_A, 11-keto-β-boswellic(KBA), and 3-acetyl-11-keto-β-boswellic acid(AKBA). A mo-dified Franz diffusion cell method was used to evaluate and compare the absorption properties of the gel paste without volatile oil and with volatile oil microemulsion. The results showed that the optimal prescription for Huoluo Xiaoling gel paste matrix was NP700(1.35 g), glycerol(7.00 g), micropowder silica gel(1.25 g), sodium carboxymethyl cellulose(0.20 g), tartaric acid(0.06 g), and glyceryl aluminum(0.04 g). The mass fractions of eight active ingredients in the paste were successively 0.48, 0.014, 0.95, 0.39, 0.57, 0.055, 0.35, and 0.97 mg·g~(-1). The results of the in vitro transdermal absorption test showed that the addition of the volatile oil or the volatile oil microemulsion promoted the transdermal absorption of the active ingredients, and the law of drug penetration conformed to the zero equation or the Higuchi equation. The gel paste prepared by the optimal prescription has good appearance and adhesion, with no residue, and has the characteristics of skeletal slow-release preparation, which is easy to reduce the number of administration, la-ying a foundation for the development of new external dosage forms of Huoluo Xiaoling Dan.

ABSTRACT

OBJECTIVE@#The aim of this case-control study was to explore the association between serum uric acid to high density lipoprotein cholesterol ratio (UHR) and the risk of nonalcoholic fatty liver disease (NAFLD) in Chinese adults.@*METHODS@#A total of 636 patients with NAFLD and 754 controls were enrolled from the Affiliated Hospital of Qingdao University, China, between January and December 2016. All patients completed a comprehensive questionnaire survey and underwent abdominal ultrasound examination and a blood test. NAFLD was diagnosed using ultrasonography after other etiologies were excluded. Logistic regression and restricted cubic spline model were conducted to evaluate the relationship of UHR with NAFLD risk.@*RESULTS@#The multivariable adjusted odds ratio (95% confidence interval, CI) for NAFLD in the highest versus lowest quartile of UHR was 3.888 (2.324-6.504). In analyses stratified by sex and age, we observed significant and positive associations between UHR and the risk of NAFLD in each subgroup. In analyses stratified by body mass index (BMI), a significant and positive association was found only in individuals with a BMI of ≥ 24 kg/m2. Our dose-response analysis indicated a linear positive correlation between UHR and the risk of NAFLD.@*CONCLUSION@#UHR is positively associated with the risk of NAFLD and may serve as an innovative and noninvasive marker for identifying individuals at risk of NAFLD.

ABSTRACT

OBJECTIVE@#Identifying novel strategies to prevent particulate matter (PM)-induced lung injury is crucial for the reduction of the morbidity of chronic respiratory diseases. The combined intervention represented by herbal formulae for simultaneously targeting multiple pathological processes can provide a more beneficial effect than the single intervention. The aim of this paper is therefore to design a safe and effective medicinal and edible Chinese herbs (MECHs) formula against PM-induced lung injury.@*METHODS@#PM-induced oxidative stress, inflammatory response and apoptosis A549 cell model were used to screen anti-oxidant, anti-inflammatory and anti-apoptotic MECHs, respectively. A network pharmacology method was utilized to rationally design a novel herbal formula. Ultra performance liquid chromatography-mass spectrometer was utilized to assess the quality control of MECHs formula. The excretion of magnetic iron oxide nanospheres of the MECHs formula was estimated in zebrafish. The MECH formula against PM-induced lung injury was investigated with mice experiments.@*RESULTS@#Five selected herbs were rationally designed to form a new MECH formula, including Citri Exocarpium Rubrum (Juhong), Lablab Semen Album (Baibiandou), Atractylodis Macrocephalae Rhizoma (Baizhu), Mori Folium (Sangye) and Polygonati Odorati Rhizoma (Yuzhu). The formula effectively promoted the magnetic iron oxide nanospheres excretion in zebrafish. The mid/high dose formula significantly prevented PM-induced lung damage in mice by enhancing the activity of SOD and GSH-Px, reducing the MDA and ROS level and attenuating the upregulation of pro-inflammatory cytokine (IL-6, IL-8, IL-1β and TNF-α), down regulating the protein expression of NF-κB, STAT3 and Caspase-3.@*CONCLUSION@#Our findings suggest that the effective MECHs formula will become a novel strategy for preventing PM-induced lung injury and provide a paradigm for the development of functional foods using MECHs.

ABSTRACT

The purpose of this study was to explore transrectal ultrasound (TRUS) findings of prostate cancer (PCa) guided by multiparametric magnetic resonance imaging (mpMRI) and to improve the Prostate Imaging Reporting and Data System (PI-RADS) system for avoiding unnecessary mpMRI-guided targeted biopsy (TB). From January 2018 to October 2019, fusion mpMRI and TRUS-guided biopsies were performed in 162 consecutive patients. The study included 188 suspicious lesions on mpMRI in 156 patients, all of whom underwent mpMRI-TRUS fusion imaging-guided TB and 12-core transperineal systematic biopsy (SB). Univariate analyses were performed to investigate the relationship between TRUS features and PCa. Then, logistic regression analysis with generalized estimating equations was performed to determine the independent predictors of PCa and obtain the fitted probability of PCa. The detection rates of PCa based on TB alone, SB alone, and combined SB and TB were 55.9% (105 of 188), 52.6% (82 of 156), and 62.8% (98 of 156), respectively. The significant predictors of PCa on TRUS were hypoechogenicity (odds ratio [OR]: 9.595, P = 0.002), taller-than-wide shape (OR: 3.539, P = 0.022), asymmetric vascular structures (OR: 3.728, P = 0.031), close proximity to capsule (OR: 3.473, P = 0.040), and irregular margins (OR: 3.843, P = 0.041). We propose subgrouping PI-RADS score 3 into categories 3a, 3b, 3c, and 3d based on different numbers of TRUS predictors, as the creation of PI-RADS 3a (no suspicious ultrasound features) could avoid 16.7% of mpMRI-guided TBs. Risk stratification of PCa with mpMRI-TRUS fusion imaging-directed ultrasound features could avoid unnecessary mpMRI-TBs.

ABSTRACT

Objective Primary ovarian small cell carcinoma of pulmonary type (SCCOPT) is a rare ovarian tumor with a poor prognosis. The platinum-based chemotherapy is the standard treatment. However, there is little research on the clinical characteristics of SCCOPT and the potential benefits of other treatments due to its low incidence. The study aims to investigate clinicopathological characteristics and treatment of SCCOPT.Methods We summarized the clinical, imaging, laboratorical and pathological characteristics of 37 SCCOPT cases, in which 6 cases were admitted to the Gansu Provincial Hospital from the year of 2008 to 2022 and 31 cases reported in 17 English and 3 Chinese literatures.Results The median age of the studied SCCOPT cases (n=37) was 56.00 (range, 22-80) years. Almost 80% of them had a stage Ⅲ or Ⅳ tumor. All patients underwent an operation and postoperative chemotherapy. Nevertheless, all cases had a poor prognosis, with a median overall survival time of 12 months. Immunohistochemically, the SCCOPT of all patients showed positive expressions of epithelial markers, such as CD56 and sex-determining region of Y chromosome-related high-mobility-group box 2 (SOX-2), and negative expressions of estrogen receptor, progesterone receptor, vimentin, Leu-7, and somatostatin receptor 2. The tumor of above 80% cases expressed synaptophysin. Only a few cases expressed neuron-specific enolase, chromogranin A, and thyroid transcription factor-1. Conclusions SCCOPT had a poor prognosis. SOX-2 could be a biomarker to be used to diagnose SCCOPT.

ABSTRACT

This study systematically evaluated the clinical efficacy and safety of Fengliao Changweikang prescription for treating acute gastroenteritis(AGE). The databases of CNKI, Wanfang, VIP, SinoMed, Medline, Cochrane Library and two clinical trial registration platforms were retrieved from inception to August 30, 2022, to collect randomized controlled trial(RCT) on Fengliao Changweikang prescription treating AGE. Two researchers independently conducted literature screening, data extraction, and risk of bias assessment according to pre-established inclusion and exclusion criteria. RevMan 5.4.1 was used for data analysis. Finally, 18 RCTs were included, involving 3 489 patients. Meta-analysis showed that compared with conventional western medicine, Fengliao Changweikang prescription improved the relief rate of abdominal pain(RR=1.27, 95%CI[1.17, 1.38],P<0.000 01); Fengliao Changweikang prescription + conventional western medicine increased the cure rate(RR=1.43, 95%CI[1.12, 1.82], P=0.004), shortened the duration of diarrhoea(RR=-1.65, 95%CI[-2.44,-0.86], P<0.000 1), abdominal pain(RR=-1.46, 95%CI[-2.00,-0.92], P<0.000 01), vomiting(RR=-2.16, 95%CI[-2.51,-1.81], P<0.000 01) and fever(RR=-2.61, 95%CI[-4.00,-1.23], P=0.000 2), down-regulated the level of interleukin-8(IL-8)(RR=-1.07, 95%CI[-1.26,-0.88], P<0.000 01), IL-6(RR=-8.24, 95%CI[-8.99,-7.49], P<0.000 01) and hypersensitive C-reactive protein(hs-CRP)(RR=-3.04, 95%CI[-3.40,-2.69], P<0.000 01) and recurrence of AGE(RR=0.20, 95%CI[0.05, 0.90], P<0.04). In conclusion, Fengliao Changweikang prescription was safe in clinical application. It was beneficial to alleviate the clinical symptoms of diarrhea, abdominal pain, vomiting, and fever, and down-regulate the levels of some serum inflammatory factors in AGE patients. However, considering that few high-quality studies have evaluated the efficacy and safety of Fengliao Changweikang prescription in treatment of AGE, further evidence is needed in the future.

ABSTRACT

【Objective】 To investigate the practice and benefit of national standardized management of type 2 diabetes in Yulin City. 【Methods】 We recruited the adult type 2 diabetes patients who sought medical help at our hospital from May 2020 to October 2022 as subjects. We collected their basic information (sex and age); measured height, weight, waist and hip circumference, and blood pressure; calculated body mass index (BMI); and detected blood glucose, c-peptide, HbA1c, biomarkers, urinary microalbumin, sensory nerve conduction velocity of lower limbs, ABI, and subcutaneous and visceral fat at the time of MMC recruited and the end of six months. T test and Mann-Whitney U rank sum test were used for measurement data and χ2 test or Fisher’s exact probability method for counting data to analyze the data. 【Results】 After 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, and visceral and subcutaneous fat in all the patients decreased, but the level of fasting c-peptide increased compared with the baseline (all P<0.05). Secondly, compared with the baseline, the control rate of HbA1c (35.21% vs. 13.71% ) and the comprehensive control rate (13.97% vs. 7.26% ) were both significantly increased at six months (P<0.05). Thirdly, after 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, TG, TC, and UA were decreased more, while the fasting c-peptide and postprandial c-peptide were increased more in the patients of the HbA1c standard group (HbA1c<7% ) than those of the non-standard group. 【Conclusion】 The multiple benefits of blood glucose, blood lipid, uric acid and islet function can be achieved by taking type 2 diabetes patients into MMC. Meanwhile, the rates of HbA1c control and comprehensively reaching the standard are significantly increased. Therefore, MMC can explore a new way for the management of type 2 diabetic patients in this area.

ABSTRACT

【Objective】 To evaluate the interference of anti-CD47 monoclonal antibody on transfusion compatibility detection, in order to establish methods for removing interference and evaluate its efficacy. 【Methods】 Blood samples from 8 patients in our clinical trial who were treated with anti-CD47 monoclonal antibody from Tianjing and Xinda were collected. ABO and Rh blood group antigen identification, direct anti-human globulin test, unexpected antibody screening test and cross-matching test were performed by ZZAP, Gamma-clone(an anti-globulin reagent lacking IgG4) and Immucor Capture-R solid phase agglutination kit. 【Results】 ABO blood group identification of 5 subjects were interfered after treatment with anti-CD47 monoclonal antibody. All 8 subjects showed 2+ to 4+ agglutination intensity on direct anti-human globulin test and 3+ to 4+ on unexpected antibody screening. The results of unexpected antibody screening by Gamma-clone and Immucor Capture-R solid phase agglutination kit were all negative, while the cross-matching test were compatible. Patients with anemia caused by CD47 monoclonal antibody treatment were transfused with 2 U suspension red blood cells, and the evaluation showed that the transfusion was effective. 【Conclusion】 The CD47 monoclonal antibody can interfere with transfusion compatibility detection, and the use of antiglobulin reagents lacking IgG4 and Immucor Capture-R solid phase agglutination kit can remove the interference, with good transfusion efficacy in patients.

ABSTRACT

Since the global COVID-19 pandemic, SARS-CoV-2 infection, which causes COVID-19, has been associated with a range of diseases whose atypical manifestations have been increasingly reported. The mild encephalitis or encephalopathy associated with reversible corpus callosum lesions or mild encephalitis/encephalopathy with reversible splenial lesion (MERS) is a rare clinical and radiographic syndrome. At present, the pathogenesis of MERS caused by COVID-19 is still unclear, and its pathogenesis may include hypoxic damage, inflammatory response, immune disorders, changes in osmotic pressure, excitatory amino acid toxicity, oxidative stress and functional abnormalities of renin-angiotensin system. This paper reports a case of severe COVID-19 complicated with MERS, and discusses the pathogenesis from a pathophysiological point of view.

ABSTRACT

Objective:To investigate the relationship between the CT images of a lateral condylar tibial plateau fractures and complete medial collateral ligament (MCL) injury.Methods:Data of 59 patients with lateral condylar fracture of tibial plateau complicated with MCL injury admitted to Tianjin Hospital from January 2020 to November 2021 were collected, including 32 males and 27 females, aged 42.4±12.3 years (range, 19-65 years), there were 26 cases of extension injury and 33 cases of flexion injury. The patients were separated into two groups: those with partial MCL injury and those with total rupture based on preoperative MR examination and intraoperative valgus stress test following fracture fixation. According to the ABC fracture classification of lateral condyle tibial plateau proposed by Sun et al., the fracture locations were determined on CT images, and the lateral plateau collapse depth (LPD) was measured. The relationship between LPD and MCL complete rupture was analyzed by receiver operating characteristic (ROC) curve.Results:Among 59 patients with lateral condylar tibial plateau fracture and MCL injury, 42 had partial injuries and 17 had complete ruptures. According to the ABC fracture classification, there were 26 cases of extension injury (involving area A), 21 cases of AB type, and 5 cases of ABC type; and 33 cases of flexion type injury, 19 cases of B type, 12 cases of BC type, and 2 cases of C type. All the 17 cases of MCL complete fracture occurred in extension injury, including type AB (14 cases) and type ABC (3 cases). The difference between the mean LPDs of the MCL full rupture group and the partial injury group was not statistically significant ( t=0.11, P=0.567), and the mean LPDs of both groups were 11.7±5.3 mm (range, 4.3-28.1 mm) and 11.5±4.8 mm (range, 3.8-23.6 mm), respectively. The area under the curve (AUC) of the ROC curve analysis was 0.504, and there was no statistical correlation between lateral platform collapse depth and MCL injury. Among the 26 patients with extensional injury area, MCL was completely ruptures in 17 cases and partially injury in 9 cases, LPD was 11.7±5.3 mm (range, 4.3-28.1 mm) and 6.6±1.8 mm (range, 3.8-9.4 mm), respectively, and the difference was statistically significant ( t=3.57, P=0.009). The best predictive cut-off value of LPD was 7.25 mm, the sensitivity was 88.2%, the specificity was 77.8%, and the AUC was 0.868. Conclusion:When the lateral condyle fracture of the tibial plateau is located in the extensional injury area (involving the A area in the ABC fracture classification) and the LPD measured on the CT image is greater than 7.25 mm, the complete rupture of the MCL should be considered. Clinical MCL repair is required after the fracture fixation surgery for improved surgical outcomes.
