Objective: To analyze the levels and distribution characteristics of blood cadmium and urinary cadmium in American adults, to analyze the relationship between blood cadmium and urinary cadmium and pulmonary function dose response, and to explore the effect of this index on the risk of chronic obstructive pulmonary disease. Methods: In March 2022, 3785 patients from 2007 to 2012 in NHANES database were selected as the subjects. Collect demography data such as gender and age, and test data such as lung function, blood cadmium concentration and Urine cadimium concentration. The relationship between blood and urine cadmium levels and lung function and pulmonary function and chronic obstructive pulmonary diease (COPD) was analyzed by Mann-Whitney U test or Kruskal-Wallis H test, multivariate linear regression and restricted cubic spline method. Results: The geometric mean of blood cadmium and urine cadmium in American adults was 0.37 g/L and 0.28 g/L, FEV(1) and FEV(1)/FVC among different cadmium exposure groups was statistically significant, and there was a negative linear dose-response relationship between serum Cd and urine Cd concentrations and FEV(1)/FVC levels (P(overall)<0.001, P(non-linear)=0.152; P(overall)<0.001, P(non-linear)=0.926). Compared with the lowest quartile concentration (Q1), the highest quartile blood cadmium concentration (Q4) (OR=1.934, P(trend)=0.000) and urinary cadmium concentration (OR=1.683, P(trend)=0.000) may increased the risk of chronic obstructive pulmonary disease. Conclusion: There is a negative correlation between blood cadmium, urinary cadmium levels and lung function in American adults, and cadmium may increase the risk of chronic obstructive pulmonary disease.

Membrane anatomy-based splenic hilar lymph node dissection for gastric cancer / 中华胃肠外科杂志

There is a consensus that selectively perform splenic lymph node dissection is necessary for high-risk patients with proximal gastric cancer to achieve radical treatment. However, there are still some outstanding issues that need to be solved during the practice of splenic lymph node dissection. These include poorly defined boundaries, technical difficulties, and blurred boundaries in No. 10 and No. 11 lymph nodes, etc. Membrane anatomy has achieved successful applications in the field of gastric and colorectal surgery in recent years. The study of membrane anatomy in the splenic hilum region is controversial due to the special location of the splenic hilum, which involves multiple organs and affiliated mesentery undergoing complex rotation, folding, and fusion during embryonic development. In this manuscript, we summarize the following points based on existing research and personal experience regarding membrane anatomy. 1. There is a membrane anatomical structure that can be used for lymph node dissection in the splenic hilum region. 2. The membrane structure in the splenic hilum region can be divided into two layers: the superficial layer is composed of the dorsal mesogastrium, and the deep layer is composed of Gerota fascia, the tail of the pancreas, and the mesentery of the transverse colon (from head to tail). 3. There is a loose space between the two layers that can be used for separation during surgery. The resection of the dorsal mesogastrium belongs to D2 dissection. The No. 10 lymph node in the deeper layer belongs to the duodenal mesentery, and the resection of the No.10 lymph node exceeds D2 dissection. The complete excision of the gastric dorsal mesentery is consistent with the D2+CME surgical mode proposed by Gong Jianping's group.

OBJECTIVE@#To study the epidemiologic characteristics of human herpes virus (HHV) activated infection in the diseases of blood system and patients received allo-HSCT by statistically analyzing the screening results of 8 human herpes viruses (HHVs) of 4164 patients in Hebei Yanda LU Dao-Pei Hospital from 2012 to 2017.@*METHODS@#PCR was used to screen 8 HHVs.@*RESULTS@#Two thousand and fifty-two patients (49.28%) were HHV-positive among 4164 patients screened. Among these patients screened, the infection spectra of 8 human HHVs in hematological diseases as well as patients received allogeneic hematopoietic stem cell transplantation of totally 2994 patients were summarized as follows: the positive rate of EBV (29.49%) was the highest, that of HCMV (23.15%), HHV-6 was 18.77% and HHV-7 was 17.64%, while the remaining 4 HHVs all≤2.1%. The rate of co-infection of various HHVs was significantly higher than that of single infection of HHV among all these disease groups except familial hemophagocytic lymphohistiocytosis, for which single EBV infection was the most common. The differences of positive rates among these 8 human HHVs in hematological diseases as well as patients received allogeneic hematopoietic stem cell transplantation were statistically significant by Chi-square test of R*C tables (χ=54.99, P＜0.05). For each HHV, the differences of positive rates among the above-mentioned disease groups were also statistically significant except HHV-8 (P＜0.05).@*CONCLUSION@#The patients with various blood diseases have different activated infection spectra of HHVs. EBV, HCMV, HHV-6 and HHV-7 are most common in HHVs infection. Different HHVs infections correlate with different hematologion diseases.

Effects of Polygonum cuspidatum on AMPK-FOXO3α Signaling Pathway in Rat Model of Uric Acid-Induced Renal Damage / 中国结合医学杂志

BACKGROUND@#To observe the effects of Chinese medicine (CM) Polygonum cuspidatum (PC) on adenosine 5'-monophosphate-activated protein kinase (AMPK), forkhead box O3α (FOXO3α), Toll-like receptor-4 (TLR4), NACHT, LRR and PYD domains-containing protein 3 (NLRP3), and monocyte chemoattractant protein-1 (MCP-1) expression in a rat model of uric acid-induced renal damage and to determine the molecular mechanism.@*METHODS@#A rat model of uric acid-induced renal damage was established, and rats were randomly divided into a model group, a positive drug group, and high-, medium-, and low-dose PC groups (n=12 per group). A normal group (n=6) was used as the control. Rats in the normal and model groups were administered distilled water (10 mL•kg) by intragastric infusion. Rats in the positive drug group and the high-, medium-, and low-dose PC groups were administered allopurinol (23.33 mg•kg), and 7.46, 3.73, or 1.87 g•kg•d PC by intragastric infusion, respectively for 6 to 8 weeks. After the intervention, reverse transcription polymerase chain reaction, Western blot, enzyme linked immunosorbent assay, and immunohistochemistry were used to detect AMPK, FOXO3α, TLR4, NLRP3, and MCP-1 mRNA and protein levels in renal tissue or serum.@*RESULTS@#Compared with the normal group, the mRNA transcription levels of AMPK and FOXO3α in the model group were significantly down-regulated, and protein levels of AMPKα1, pAMPKα1 and FOXO3α were significantly down-regulated at the 6th and 8th weeks (P<0.01 or P<0.05). The mRNA transcription and protein levels of TLR4, NLRP3 and MCP-1 were significantly up-regulated (P<0.01 or P<0.05). Compared with the model group, at the 6th week, the mRNA transcription levels of AMPK in the high- and medium-dose groups, and protein expression levels of AMPKα1, pAMPKα1 and FOXO3α in the high-dose PC group, AMPKα1 and pAMPKα1 in the mediumdose PC group, and pAMPKα1 in the low-dose PC group were significantly up-regulated (P<0.01 or P<0.05); the mRNA transcription and protein levels of TLR4 and NLRP3 in the 3 CM groups, and protein expression levels of MCP-1 in the medium- and low-dose PC groups were down-regulated (P<0.01 or P<0.05). At the 8th week, the mRNA transcription levels of AMPK in the high-dose PC group and FOXO3α in the medium-dose PC group, and protein levels of AMPKα1, pAMPKα1 and FOXO3α in the 3 CM groups were significantly up-regulated (P<0.01 or P<0.05); the mRNA transcription levels of TLR4 in the medium- and low-dose PC groups, NLRP3 in the high- and low-dose PC groups and MCP-1 in the medium- and low-dose PC groups, and protein expression levels of TLR4, NLRP3 and MCP-1 in the 3 CM groups were down-regulated (P<0.01 or P<0.05).@*CONCLUSION@#PC up-regulated the expression of AMPK and its downstream molecule FOXO3α and inhibited the biological activity of TLR4, NLRP3, and MCP-1, key signal molecules in the immunoinflammatory network pathway, which may be the molecular mechanism of PC to improve hyperuricemia-mediated immunoinflflammatory metabolic renal damage.

Clinical characteristics and prognosis of 34 cases of acute myeloid leukemia with FLT3 internal tandem duplication and MLL gene rearrangement / 中华血液学杂志

Objective: To analyze the clinical characteristics and prognosis of 34 cases of acute myeloid leukemia (AML) with FLT3 internal tandem duplication (FLT3-ITD) and MLL gene rearrangement. Methods: The clinical data of 34 AML patients with FLT3-ITD and MLL gene rearrangement was compared and analyzed for the therapeutic efficacy, prognostic factors when treated with chemotherapy, chemotherapy combined with targeted therapy or allogenic hematopoietic stem cell transplantation (allo-HSCT). Results: Of the thirty-four cases with median age 41 (4-71) years old, 63.6% presented with white blood cells (WBC) greater than 30×10(9)/L, 39.4% greater than 50 × 10(9)/L respectively on admission. M(5) (35.3%) made up the highest proportion. The cytogenetic abnormality reached 61.8%, of which the complex cytogenetic abnormality accounted for 11.8%. Eleven patients (32.35%) had both FLT3-ITD and MLL gene abnormalities. In addition to FLT3 and MLL abnormalities, 23 patients (67.6%) had one or more other gene abnormalities (multiple gene abnormalities). Of the 34 cases, 29.4% patients went into complete remission (CR) after two courses of chemotherapy. 20.6% (7 patients) went into CR after 3 or more courses of chemotherapy. The rate of early relapse in the CR group was 52.9%. Patients with WBC>50×10(9)/L or multiple gene abnormalities had a lower remission rate (7.7%, 5.4%) after two courses of chemotherapy. CR rate for the patients with more than three gene abnormalities was 0. The total 2-year overall survival (OS) in the 34 patients was 28.8% (95% CI 13.5%-46.0%) and the disease-free survival (DFS) was 27.1% (95% CI 12.5%-44.0%). Of the 18 patients treated with chemotherapy alone or chemotherapy combined with targeted therapy, 17 cases died within 2 years and 1 lost follow-up after giving up treatment. For the 16 patients received allo-HSCT, the 3-year OS was 43.4% (95% CI 13.7%-70.4%) and DFS 42.7% (95% CI 13.4%-69.7%). Conclusion: AML patients with FLT3-ITD and MLL gene rearrangement often presented with M(5), accompanied by hyperleukocytosis, cytogenetic or multiple gene abnormalities. Those patients were observed to have low response rate and high early relapse when treated with chemotherapy without allo-HSCT. Patients had multiple gene abnormalities may be an important poor prognostic factor. Allo-HSCT is an effective treatment which could significantly improve the prognosis and survival of AML patients with FLT3-ITD and MLL gene abnormalities.

Huanglian jiedu decoction regulated and controlled differentiation of monocytes, macrophages, and foam cells: an experimental study / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effect of Huanglian Jiedu Decoction (HLJDD) in in vivo regulating differentiation of monocytes in an apolipoprotein E knockout (ApoE(-/-)) mouse model, and to observe the effect of HLJDD-containing serum in in vitro regulating differentiation of macrophages and foam cells.</p><p><b>METHODS</b>Fifteen apoE(-/-) mice were randomly divided into the common diet group, the hyperlipidemia group, and the hyperlipidemia +HLJDD treatment group, 5 in each group. Mice in the common diet group were fed with a chow diet. Mice in the hyperlipidemia group were fed with high cholesterol wild diet (WD). Those in the hyperlipidemia +HLJDD treatment group were fed with high cholesterol WD supplemented with HLJDD. All mice were fed for 4 weeks. Five C57BL/6 wild types were recruited as the wild common diet control group. HLJDD was administered to mice in the hyperlipidemia + HLJDD treatment group by gastrogavage at the daily dose of 5 g/kg. Equal volume of purified water was given by gastrogavage to mice in the rest 3 groups. Four weeks later, subtypes of monocytes in the peripheral blood were detected by FACS. HLJDD administered to another 30 SD rats by gastrogavage at the daily dose of 5 g/kg, once for every 12 h for 5 times in total, thereby preparing 5% HLJDD containing serum to intervene the differentiation of in vitro primary bone marrow-derived macrophage (BMDM) and foam cells. The M2 subtype surface receptor CD206 of macrophages and foam cells were detected by FACS. The expression of Nos2 and Arg1 genes were assayed by Real-time PCR.</p><p><b>RESULTS</b>The ratio of inflammatory subset of monocytes (Ly6C(high)) increased in the peripheral blood after ApoE(-/-) mice were fed with high fat diet for 4 weeks. HLJDD significantly decreased the ratio of inflammatory subset of monocytes (P < 0.05). Compared with the vehicle serum, 5% HLJDD containing serum significantly increased differentiation of CD206 + M2 BMDM (P = 0.034). Results of real-time quantitative PCR showed that the expression level of Arg1 mRNA could be up-regulated by HLJDD containing serum (P < 0.05), and that of Nos2 mRNA down-regulated (P = 0.017). ox-LDL induced the differentiation of M2 subtype foam cells from BMDM, and HLJDD containing serum could further elevate the ratio of CD206 + M2 foam cells and increase the Arg1 mRNA expression level (both P < 0.01). HLJDD containing serum could inhibit the inversion of M2 subtype of foam cells to M1 subtype induced by Th1 factors, significantly elevate the Arg1 mRNA expression level, and decrease the Nos2 mRNA expression level (all P < 0.01).</p><p><b>CONCLUSIONS</b>HLJDD could lower hyperlipidemia induced inflammatory monocyte subtype ratios in the peripheral blood of ApoE(-/-) mice. HLJDD containing serum promoted in vitro differentiation of M2 macrophages and foam cells. HLJDD attenuated and inhibited the occurrence and development of atherosclerosis induced by hyperlipidemia possibly through regulating the functional differentiation of monocytes, macrophages, and foam cells.</p>

<p><b>OBJECTIVE</b>To compare the difference in the clinical efficacy on primary trigeminal neuralgia (PTN) between the comprehensive therapy of electroacupuncture (EA) at qi streets acupoints combined with spinal regulation method and medication with carbamazepine (CBZ).</p><p><b>METHODS</b>Sixty patients were randomized into a comprehensive therapy group (30 cases) and a medication group (30 cases). In the comprehensive therapy group, the acupoints at qi streets on the head such as Taiyang (EX-HN 5) and Sishencong (EX-HN 1) and those at qi streets on the chest and abdomen such as Shenshu (BL 23), Zhongwan (CV 12) and Guanyuan (CV 4), etc. were selected. After arrival of qi, EA was attached on 2 to 4 groups of acupoints. After acupuncture, the spinal regulation method was applied. This comprehensive therapy was given once a day. In the medication group, CBZ was used for oral administration, 100 mg at the first time, twice a day, and 400 to 600 mg each day as the maintenance dose. Separately, before and after treatment, in 2 and 6 months in follow-up, pain rating index (PRI), life satisfaction index B (LSI-B) and hamilton depression scale (HAMD) were adopted to evaluate comprehensively the clinical efficacy in the two groups and compare the adverse reaction during the treatment between the two groups.</p><p><b>RESULTS</b>After treatment, the curative and markedly effective rate in the comprehensive therapy group was 76.7% (23/30), which was better than 63.3% (19/30) in the medication group (P < 0.01). The difference in PRI was not significant after treatment between the two groups (all P > 0.05). In 2 and 6 months follow-up, PRI grade in the comprehensive therapy group was superior to that of the medication group (both P<0. 05). After treatment and in follow-up, HAMD score was all reduced in the two groups (P < 0.01, P < 0.05) and the result in follow-up in the comprehensive therapy group was significant as compared with that in the medication group (all P<0. 05). After treatment, LSI-B score was increased obviously in the two groups (all P < 0.05) and the result in the comprehensive therapy group was better than that in the medication group (P < 0.05). The incidence of adverse reaction in the comprehensive therapy group was 16.7% (5/30), which was lower than 30.0% (9/30, P < 0.01) in the medication group.</p><p><b>CONCLUSION</b>The comprehensive therapy of EA at qi streets acpoints combined with spinal regulation method achieves the long-term efficacy on PTN as compared with oral administration of CBZ in terms of the improvement of psychological condition, analgesia and life quality. It is the safe, effective and stable therapy.</p>

Lumbar disc herniation treated with qi pathway intervention and spinal adjustment: a randomized controlled trial / 中国针灸

<p><b>OBJECTIVE</b>To compare the efficacy difference in the treatment of lumbar disc herniation (LDH) between the comprehensive therapy of qi pathway intervention and the spinal adjustment and the conventional therapy of acupuncture and Tuina and explore the analgesic mechanism.</p><p><b>METHODS</b>Seventy-one cases were randomized into a comprehensive therapy group (36 cases) and a conventional therapy group (35 cases). In the comprehensive therapy group, the acupoints in the region of abdominal qi pathway were selected and stimulated manually with both hands. In combination, the spinal adjustment therapy was applied. In the conventional therapy group, Shenshu (BL 23), Dachangshu (BL 25), Huantiao (GB 30) and Chengfu (BL 36) on the affected side were selected and stimulated with the conventional needling technique. Additionally, the routine Tuina therapy was applied. Before and after treatment, the visual analogue scale (VAS), Oswestry disability index (ODI) questionnaire, the health related quality of life (SF-36) questionnaire and the level of serum tumor necrosis factor (TNF-alpha) were adopted to determine analgesic effect and clinical efficacy.</p><p><b>RESULTS</b>In the comprehensive therapy group, the curative and effective rate was 91.7% (33/36), which was apparently superior to 77.1% (27/35) in the conventional therapy group (P < 0.05). The analgesic effect in the first 10 treatments in the comprehensive therapy group was apparently superior to that in the conventional therapy group (P < 0.05). ODI after treatment was improved significantly in both groups (both P < 0.05), in which the result in the comprehensive therapy group was superior to that in the conventional therapy group (P < 0.05). After treatment, the SF-36 values of gener al health, bodily pain, physiological functioning, social functioning and emotional functioning in the comprehensive therapy group were superior to that in the conventional therapy group (all P < 0.05). After 15 treatments, the level of serum TNF-alpha in the comprehensive therapy group was lowered as compared with that before treatment and lower apparently than that in the conventional therapy group (P < 0.05); after 30 treatments, it was also lower than that in conventional therapy group (P < 0.05).</p><p><b>CONCLUSION</b>In the guide of the theory of qi pathway, the comprehensive therapy of acupuncture and spinal adjustment intervention achieves the quick and good efficacy on LDH as compared with the conventional acupuncture and Tuina and improves the quality of life for the patients to certain extent. The analgesic effect of this therapy is relevant with the decrease of serum TNF-alpha.</p>
