ObjectiveTo explore the pathological mechanism-syndrome-treatment patterns of approved Chinese patent medicines （CPMs） that treat collateral disorders， providing a reference for the principle of "treating different diseases with the same therapy" in collateral pathology. MethodsCPMs that apply treatment strategies based on collateral disorders were identified from the Pharmacodia database by extracting information from the "efficacy" or "indications" sections of drug package inserts. A database was established to extract the names and compositions of the CPMs， as well as their indications， related traditional Chinese medicine （TCM） symptoms， disease locations （affected areas）， and pathological factors. Frequency statistics were performed. Using the Apriori algorithm， an association rule analysis was conducted on CPMs and disease-location combinations related to the top three most frequent pathological factor combinations. Core formulas for these combinations were identified and analyzed through drug network analysis and MCODE module clustering. ResultsA total of 660 CPMs targeting collateral disorders were retrieved， involving 299 indications， 323 TCM symptoms， 21 disease locations， 19 pathological factors， and 124 pathological factor combinations. The most frequent pathological factor combinations were blood stasis （involved in 109 CPMs， 16.52%）， exogenous wind （外风） -cold-dampness （involved in 43 CPMs， 6.52%）， and qi deficiency-blood stasis （involved in 42 CPMs， 6.36%）. Analysis of the core formulas for these combinations revealed common ingredients such as Honghua （Carthami Flos）， Chuanxiong （Chuanxiong Rhizoma）， Danggui （Angelicae Sinensis Radix）， and Dilong （Pheretima）. ConclusionCollateral disorders involve a wide range of pathogenesis and represent a fundamental mechanism in the onset and development of various diseases， characterized by obstruction and stagnation. The primary therapeutic principle is unblocking of the collaterals. Blood stasis obstructing the collaterals is the core pathological basis， and the strategy of activating blood circulation and resolving stasis to unblock the collaterals should be central to the treatment. The core medication pattern involves combining blood-activating and stasis-resolving herbs with insect-derived medicinals that unblock collaterals. Exogenous wind is often the initiating patholo-gical factor in colla-teral disorders， and the appropriate addition of wind-dispelling herbs can enrich the treatment strategies for such conditions.

Objective To investigate the correlation between the expression of long non-coding ribonucleic acid growth arrest specific 5(lncRNA GAS5),phospholysine phosphohistidine inorganic pyrophosphate phos-phatase(LHPP)and epithelial-mesenchymal transition(EMT)in cancer tissues of patients with non-small cell lung cancer(NSCLC)and its clinical significance.Methods Cancer tissues and adjacent tissues of 90 patients with NSCLC who underwent surgical resection in the First Hospital Affiliated to Hebei North College from June 2018 to January 2020 were collected.The expressions of lncRNA GAS5,LHPP and EMT-associated pro-teins[E-calmodulin(E-Cad),N-calmodulin(N-Cad),and vimentin(VIM)]were detected by real-time fluores-cence quantitative polymerase chain reaction.The relationship between lncRNA GAS5 and LHPP mRNA and clinicopathological features in cancer tissues of NSCLC patients was analyzed,and the correlation between ln-cRNA GAS5 and LHPP mRNA and EMT-associated proteins expression in cancer tissues of NSCLC patients was analyzed by Pearson correlation.Kaplan-Meier method was used to plot the survival curves of NSCLC pa-tients with different lncRNA GAS5 and LHPP mRNA expressions,and multivariate Cox regression was used to analyze the prognostic factors of NSCLC patients.Results The expressions of lncRNA GAS5,LHPP mR-NA and E-Cad mRNA in cancer tissues of NSCLC patients were lower than those in adjacent tissues,while the expressions of N-Cad mRNA and VIM mRNA were higher than those in adjacent tissues,with statistical sig-nificance(P＜0.05).Pearson correlation analysis showed that lncRNA GAS5 in cancer tissues of NSCLC pa-tients was positively correlated with E-Cad mRNA expression(r=0.724,P＜0.001),and negatively correla-ted with N-Cad mRNA and VIM mRNA expression(r=-0.699,-0.689).P＜0.001);lncRNA GAS5 was positively correlated with LHPP mRNA expression(r=0.651,P＜0.001).The mRNA expressions of ln-cRNA GAS5 and LHPP in cancer tissues of NSCLC patients with different degrees of differentiation,tumor TNM stage and lymph node metastasis were significantly different(P＜0.05).Kaplan-Meier survival curve a-nalysis showed that the 3-year overall survival rate in the lncRNA GAS5 high expression group[68.18％(30/44)]was higher than that in the lncRNA GAS5 low expression group[36.96％(17/46)].The 3-year overall survival rate in the high LHPP mRNA expression group[67.39％(31/46)]was higher than that in the lowLHPP mRNA expression group[36.36％(16/44)],and the difference was statistically significant(x2=10.274,10.322,P＜0.05).Low differentiation,TNM stage Ⅲ and lymph node metastasis were independent risk factors for death in NSCLC patients,and lncRNA GAS5≥1.32 and LHPP mRNA≥1.12 were independ-ent protective factors(P＜0.05).Conclusion The low expression of lncRNA GAS5 and LHPP mRNA in cancer tissues of patients with NSCLC is related to EMT-associated proteins expression,differentiation de-gree,tumor TNM stage,lymph node metastasis and prognosis,and may become a new target for the diagnosis and treatment of NSCLC.

Objective:To explore the correlation between high cholinergic pathway signaling and cognitive function in patients with Parkinson disease(PD) accompanied with sleep disorder.Methods:PD patients admitted from 2017 to 2022 were divided into PD with sleep disorder group (PD-SD group) ( n=56) and PD without sleep disorder group (PD-NSD group) ( n=41) according to the Parkinson's disease sleep scale (PDSS) score. All participants underwent magnetic resonance imaging examination.All patients were evaluated by the PDSS, Hoehn-Yahr (H-Y), Montreal cognitive assessment scale (MoCA), and cholinergic pathways hyper intensities scale (CHIPS). The difference of cognitive function between the two groups and the correlation between CHIPS and cognitive function were analyzed.Independent sample t-test, Spearman correlation analysis, and binary Logistic regression analysis were performed on the data by SPSS 26.0 statistical software. Results:(1)The MoCA score of the PD-SD group (22.00 (5.00)) was lower than that of the PD-NSD group (26.00 (5.00)) ( Z=-3.830, P<0.05). The total and all aspects scores of CHIPS in PD-SD group were higher than those in PD-NSD group(the total score of the low external capsule: 12.00(8.00), 0(8.00), the total score of the high external capsule: 12.00(2.00), 6.00(9.00), the total score of the radial crown: 8.00(0), 4.00(4.00), the total score of the centrum semiovale: 3.00(4.00), 0(2.00), the total score of the right side: 16.00(9.00), 5.00(10.00), the total score of the left side: 17.00(6.00), 7.00(9.00), the total score of CHIPS: 32.00(14.00), 14.00(20.00))( Z=-5.081, -5.873, -4.933, -3.211, -5.562, -6.232, -5.995, all P<0.05). (2)The correlation analysis between the score of CHIPS and cognitive function in the PD-SD group showed that, the total score of the low external capsule ( r=-0.286), the total score of the centrum semiovale ( r=-0.307), the total score of the right side ( r=-0.376), the total score of the left side ( r=-0.284) and the total score of CHIPS ( r=-0.349) were negatively correlated with MoCA(all P<0.05). (3)Binary Logistic regression analysis showed that white matter lesions in centrum semiovale, low inner capsule, right and left leukodystrophy were not influence factors for cognitive impairment (all P>0.05). Conclusion:PD patients with sleep disorders have lower cognitive function scores, higher CHIPS scores, and significant changes in white matter lesions compared to those without sleep disorders. In PD patients with sleep disorders, the higher the CHIPS score, the lower the cognitive function score, and the more significant the rate of cognitive impairment occurrence and development.

The combination of yang-raising and dampness-removing medicinal （212 times）， often using Qianghuo （Hansenia weberbaueriana）， Chaihu （Elephantopus scaber）， Fangfeng （Carum carvi）， and this type of medicinal is most frequently used for headache， and atrophy-flaccidity is the most frequent disease. The combination of medicinal for specialised diseases was used the least frequently （39 times）. ConclusionCangzhu-Huangbai pair were often combined with medicinal of yang-raising and dampness-removing， spleen-fortifying and dampness-removing， and heat-clearing and dampness-draining to expel dampness pathogen， at the same time combined with disease-specific medicinal to treat disease and syndrome together.

BACKGROUND:Currently,there have been a variety of conservative and surgical treatment plans for spontaneous osteonecrosis of the knee,achieving excellent results.However,a broad consensus on indication and guide of surgical treatment has not been announced.In clinical practice,there is still a misunderstanding that unicondylar replacement or total knee arthroplasty should be performed upon the discovery of spontaneous osteonecrosis of the knee,while an urgent need for universal access to the concept of stepwise therapy. OBJECTIVE:To summarize and find the factors leading to the poor effect of conservative treatment in spontaneous osteonecrosis of the knee,which occurred on the medial femoral condyle,from the literature and clinical cases,at the same time,combined with the Koshino stage,to propose the strategy of stepwise spontaneous osteonecrosis of the knee treatment on the medial femoral condyle. METHODS:A systematic search of the literature database was conducted to summarize the factors leading to poor outcomes of conservative treatment in spontaneous osteonecrosis of the medial femoral condyle.Meanwhile,according to the Clinical&Health Records for analytics&Sharing system,the cases receiving conservative and surgical treatment in spontaneous osteonecrosis of the medial femoral condyle in the Department of Orthopedics of Guangdong Provincial Hospital of Chinese Medicine from January 2017 to January 2023 were analyzed retrospectively,then the causes of success and failure in typical cases were summarized and analyzed. RESULTS AND CONCLUSION:(1)Early diagnosis and treatment of spontaneous osteonecrosis of the knee were very important for prognosis.For sudden knee pain in some patients,if no obvious abnormality was found in the X-ray examination,and the symptoms persisted and could not be relieved for more than 1 week,an MRI examination was recommended to detect early spontaneous osteonecrosis of the knee.(2)The X-ray images of Koshino stage 1 and stage 2 of spontaneous osteonecrosis of the medial femoral condyle were difficult to be distinguished,which needed to be probed by MRI.MRI images of Koshino stage 1 were mainly characterized by bone marrow edema,and an osteonecrosis area with a clear boundary was not formed,while MR images of Koshino stage 2 showed a necrotic area with a clear boundary.(3)Five factors leading to the poor effect of conservative treatment on spontaneous osteonecrosis of the medial femoral condyle were summarized:a.The necrotic area was＞5 cm2;b.The necrotic area accounted for more than 40%of the condyle;c.relative compression percentage of medial meniscus≥33%(with or without medial meniscus injury and subchondral bone marrow edema);d.MRI depth of necrotic area(anterior-posterior diameter of sagittal necrotic area)＞20 mm;e.varus deformity of lower limb＞6°.(4)Conservative treatment of spontaneous osteonecrosis of the knee in Koshino stage 1 was good.For spontaneous osteonecrosis of the knee in Koshino stage 2,conservative treatment was preferred or combined with drilling decompression.If there was no relief or improvement of symptoms or in MRI after 3 months,while the patient had any of the previous five factors,then knee preservation surgery should be considered.For spontaneous osteonecrosis of the knee in Koshino stage 3 and stage 4,knee preservation surgery should be selected based on the previous five factors,including age,gender and activity level of the patient.Total knee arthroplasty was used for spontaneous osteonecrosis in Koshino stage 4,which was associated with symptomatic patellofemoral arthritis,valgus alignment,or necrotic area,which greatly affected the stability of unicondyle prosthesis.

Objective:To analyze the level of interleukin-36(IL-36) family cytokines in peripheral blood, and explore the regulatory role of recombinant human IL-36α in monocyte function in patients with diabetic kidney disease(DKD).Methods:A total of 41 type 2 diabetes mellitus(T2DM) patients, 36 DKD patients, and 20 controls were consecutively enrolled. Plasma and peripheral blood mononuclear cells(PBMCs) were isolated. Enzyme-linked immunosorbent assay(ELISA) was used to measure plasma levels of IL-36α, IL-36β, IL-36γ, and IL-36 receptor antagonist(IL-36Ra). PBMCs were sorted, and real-time quantitative PCR was performed to detect the mRNA expression of IL-36 receptor subunits in monocytes. Monocytes were stimulated with recombinant IL-36α, and levels of cytotoxic molecules and cytokines in the culture supernatant were measured. Flow cytometry was used to assess the expressions of programmed death receptor-1(PD-1) and cytotoxic T-lymphocyte-associated protein 4(CTLA-4). Co-culture of monocytes with Vero cells was performed to evaluate monocyte cytotoxicity.Results:Plasma levels of IL-36α and IL-36β in the T2DM and DKD groups were significantly higher than those in the control group. The DKD group also showed higher plasma levels of IL-36α compared to the T2DM group( P<0.05). There were no significant differences in IL-36γ and IL-36Ra levels among the three groups( P>0.05). The mRNA expression of IL-36 receptor subunits in monocytes was comparable among the three groups( P>0.05). The DKD group had higher level of tumor necrosis factor-alpha(TNF-α) compared to the control and T2DM groups( P<0.05). The levels of PD-1 and CTLA-4 were lower in the DKD group than those in the control and T2DM groups( P<0.05). The proportion of monocyte-induced Vero cell death was significantly higher in the DKD group compared to the control and T2DM groups( P<0.05). After stimulation with recombinant human IL-36α, monocytes from DKD patients showed a significant increase in the secretion of granzyme B and TNF-α( P<0.05), as well as an increased proportion of monocyte-induced Vero cell death( P=0.024). Conclusion:In DKD patients, elevated IL-36α and granzyme B levels in monocytes enhance monocyte function.

Objective:To investigate the distribution of physical and chemical water improvement areas of drinking water-borne endemic fluorosis in Inner Mongolia Autonomous Region, as well as the use of household water purifiers.Methods:From April to October 2021, a survey was conducted in a drinking water-borne endemic fluorosis areas in Inner Mongolia Autonomous Region where physical and chemical water improvement was carried out. The survey included the basic situation of the affected villages (number of permanent households, number of permanent residents, historical water fluoride content) and the use of residential water purifiers. Household peripheral water samples were collected to test the water fluoride content. Water purifier installation rate, normal usage rate, qualified water fluoride rate in normal usage, and the proportion of households covered by filter replacement departments were calculated.Results:In Inner Mongolia Autonomous Region, the physical and chemical water improvement areas of drinking water-borne endemic fluorosis were distributed in 2 735 villages in 11 leagues (cities) throughout the region, with 192 950 permanent households and 540 216 permanent residents. The average historical water fluoride content in all leagues (cities) was 2.18 mg/L, and the current average water fluoride content was 0.40 mg/L. A total of 134 763 water purifiers were installed, with an installation rate of 69.84% (134 763/192 950). A total of 10 773 households were surveyed, with 10 396 households using water purifiers normally and a normal usage rate of 96.50% (10 396/10 773). Among them, 10 158 households had qualified water fluoride of normal usage, with a qualified water fluoride rate of 97.71% (10 158/10 396). Of the 10 396 households using water purifiers normally, 3 974 households (38.23%) had filter cartridges used within one year, and 3 961 households had qualified water fluoride, with a qualified rate of water fluoride of 99.67% (3 961/3 974). Six thousand four hundred and twenty-two households (61.77%) had filter cartridges used for more than one year, with 6 197 households had qualified water fluoride and a qualified rate of water fluoride of 96.50% (6 197/6 422). There was a statistically significant difference in the qualified rate of water fluoride between purifiers with different filter cartridge usage times (χ 2 = 110.73, P < 0.001). Among the 10 773 surveyed households, the filter cartridges replacement department covered 10 470 households, accounting for 97.19% (10 470/10 773). Conclusions:In Inner Mongolia Autonomous Region, the physical and chemical water improvement areas of drinking water-borne endemic fluorosis are widely distributed, and the normal usage rate of household water purifiers is relatively high. The qualified rate of water fluoride in household water purifiers with filter cartridges used for more than one year is low.

Objective:To investigate the arsenic metabolism pattern and possible influencing factors in the population in drinking-water-borne endemic arsenic poisoning (drinking-water-borne arsenic poisoning for short) areas.Methods:In December 2004, a cluster sampling method was used to select arsenic poisoning population (arsenic poisoning group) and healthy population (control group) in drinking-water-borne arsenic poisoning area of Bayannur City, Inner Mongolia Autonomous Region as the survey subjects. A questionnaire survey was conducted. Arsenic content in drinking water at home of survey subjects, the levels of urinary arsenic and its metabolites, including [trivalent arsenic (As Ⅲ), inorganic arsenic (iAs), monomethylarsenic acid (pentavalent, MMA V), dimethylarsenic acid (pentavalent, DMA V), total arsenic (tAs), percentage of inorganic arsenic (iAs%), percentage of monomethylarsenic acid (MMA%), percentage of dimethylarsenic acid (DMA%), primary methylation index (PMI), secondary methylation index (SMI)] were tested using high performance liquid chromatography-inductively coupled plasma mass spectrometry; nail arsenic and nail selenium levels were tested using atomic fluorescence spectrometer. The influencing factors of arsenic metabolism pattern were analyzed by multiple linear regression. Results:A total of 536 survey subjects were included, including 155 individuals in the arsenic poisoning group and 381 in the control group. The water arsenic level ranged from 0.0 to 825.7 μg/L. Compared with the control group, there was no significant difference in the distribution of gender, education level and dental fluorosis in the arsenic poisoning group ( P > 0.05), but there were significant differences in the distribution of age, marital status, smoking, drinking and water arsenic ( P < 0.05). Compared with the control group, the levels of urinary As Ⅲ, iAs, MMA V, DMA V, tAs, MMA%, MMA/DMA and nail arsenic in the arsenic poisoning group were higher ( P < 0.05), while the levels of urinary DMA%, SMI and nail selenium were lower ( P < 0.05); but there was no statistically significant difference in the levels of urinary iAs% and PMI ( P > 0.05). Gender, education level, depth of wells, water arsenic, total number of wells and nail arsenic were the influencing factors of urinary As Ⅲ (β = - 19.82, - 23.83, 0.61, 0.21, 7.26, 2.98, P < 0.05). Age, depth of wells, water arsenic and nail arsenic were the influencing factors of urinary tAs (β = 3.18, 3.25, 1.31, 15.59, P < 0.05). Gender, education level, depth of wells, water arsenic, total number of wells and nail arsenic were the influencing factors of urinary iAs (β = - 20.47, - 25.90, 0.64, 0.25, 7.87, 3.11, P < 0.05). Age, gender, education level, water arsenic and nail arsenic were the influencing factors of urinary MMA V (β = 0.52, - 17.07, - 21.84, 0.22, 2.77, P < 0.05). Age, depth of wells, water arsenic and nail arsenic were the influencing factors of urinary DMA V (β = 2.35, 2.47, 0.85, 9.22, P < 0.05). Conclusions:Compared with healthy individuals, there are differences in arsenic metabolism pattern among individuals with drinking-water-borne arsenic poisoning. Age, gender, education level, depth of wells, water arsenic, total number of wells and nail arsenic may be influencing factors of different arsenic metabolism patterns.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

OBJECTIVE To explore the self precipitation source of Erhuang powder, determine the content of related components and its efficacy on HeLa cells. METHODS Bifurcation study to identify the main compatibility of precipitating. The self precipitation, supernatant and extract of Erhuang powder were analyzed by UHPLC-Q-Exactive MS. The main compounds in Coptidis Rhizoma and Catechu, catechin, epicatechin, epicberberine, coptisine, berberine and palmatine were selected as controls. A analysis method of UHPLC for self precipitation, supernatant and extract of Erhuang powder was established and the related components were quantitatively determined. The effects of self precipitation, supernatant and extract on HeLa cells were evaluated by MTT method and flow cytometry. RESULTS A slight flocculation precipitate appeared when the decoction of Erhuang powder was mixed in pairs, while a large amount of flocculation appeared when the decoction of Coptidis Rhizoma and Catechu water was mixed. The self precipitation, supernatant and extract samples contained 39 compounds, which were mainly alkaloids and phenolic acids. The contents of catechin and berberine in the 6 index components were mostly, which accounted for 73.56% of the total content of the index components in self precipitation and 61.89% of the total content of the index components in extract. Inhibition effect on HeLa cells: extract ≈ self precipitation > supernatant, and inducing apoptosis: self precipitate ≈ extract, supernatant had no apoptosis-inducing effect. CONCLUSION Coptidis Rhizoma-Catechu is the main compatible formula for precipitation formation. The self precipitation and extracts of Erhuang powder are mainly alkaloids and phenolic acids, among which berberine and catechin are high in content and can be used as representative components. The effect of self-precipitation and extract on HeLa cells was better than that of supernatant. This basically indicates that the self precipitation components and pharmacological effects of Erhuang powder are similar to those of the extract.
