ABSTRACT
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 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.

ABSTRACT
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.

ABSTRACT
Objective To observe the effects of perfusion of the gastrodin in abdominal aorta for alleviating the spinal cord ischemia reperfusion injury (SCIRI). Methods A total of 36 New Zealand white rabbits were divided randomly into sham-operated group (group S), control group (group C) and gastrodin group (group G), 12 rabbits for each group. Aorta abdominalis infrarenalis blocking method was applied to establish the SCIRI model. The changes of motor evoked potentials (MEPs) before the ischemia and on 30 min, 60 min, 6 h, 12 h and 24 h of reperfusion of the gastrodin were respectively recorded, and the neurologic function score before the ischemia, on the 6 h, 12 h and 24 h of the reperfusion of the gastrodin were assessed. And the changes of the concentration of serum neuron specific enolase (NSE), interleukin (IL)-lβ and IL-8 were measured before the ischemia, after 45 min of ischemia, and on 30 min, 60 min, 6 h, 12 h and 24 h of reperfusion of gastrodin. Then the levels of spinal cord nerve cells mitochondrial superoxide dismutase (SOD), reactive oxygen species (ROS), glutathione peroxidase (GSH-PX), malondialdehyde (MDA), total antioxidant capacity (T-AOC) and mitochondrial swelling degree (MSD) were tested and the histopathologic changes in spinal cord tissues were observed. Results The levels of the NSE, IL-lβ, IL-8, ROS, MDA and MSD of group C were all significantly elevated after the ischemia (P < 0.01); the levels of the spinal nerve cell mitochondria SOD, GSH-PX and T-AOC were all significantly reduced (P < 0.01), MEPs and spinal cord tissue pathology were damaged significantly (P < 0.01). The rate of motor neuron abnormalities and the damages of spinal cord tissue pathology of group G were significantly milder than those of group C (P < 0.01); the levels of NSE, IL-lβ, IL-8, ROS, MDA and MSD were significantly lower than those of group C (P < 0.01), but the levels of SOD, GSH-PX and T-AOC were all significantly higher than those of group C (P < 0.01), and the recovery of neurologic function score during the reperfusion of gastrodin was significantly faster than group C (P < 0.01). Conclusions Perfusion of the gastrodin in abdominal aorta can alleviate the spinal cord ischemia reperfusion injury by promoting the mitochondrial antioxidant capacity and inhibiting the inflammatory reaction.

ABSTRACT
<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>

<p><b>OBJECTIVE</b>To compare the difference in the efficacy of cervical spondylosis between the combined therapy of spinal balancing and the intervention of pathway of qi and the conventional acupuncture and massage therapy.</p><p><b>METHODS</b>Two hundred and seventy-four cases of cervical spondylosis were randomized into a spinal balancing group and a conventional acupuncture group, 137 cases in each one. In the spinal balancing group, the points on the pathway of qi on the head and on the abdomen were selected [the pathway of qi on the head: Baihui (GV 20), Tianzhu (BL 10), Wangu (GB 12) and the others; the pathway of qi on the abdomen: Shenshu (BL 23), Guanyuan (CV 4), Zhongji (CV 3) and the others]. The bimanual needling technique was applied in combination with spinal balancing therapy. In the conventional acupuncture group, the points were Jiaji (EX-B 2) (C3-C7), Fengchi (GB 20), Wangu (GB 12), Baihui (GV 20), etc. The conventional acupuncture technique and massage therapy were adopted. The neck pain questionnaire (NPQ) was adopted to assess the clinical efficacy of the two groups before and after treatment.</p><p><b>RESULTS</b>NPQ score was all improved significantly after treatment in the two groups (all P < 0.05). The result in the spinal balancing group was superior to the conventional acupuncture group (P < 0.05). The curative and effective rate was 83.2% (114/137) in the spinal balancing group, which was better than 69.3% (95/137) in the conventional acupuncture group (P < 0.05). In terms of the types of cervical spondylosis, from high to low, the efficacy sequence was cervical type, nerve root type, vertebral artery type, sympathetic nerve type and spinal cord type.</p><p><b>CONCLUSION</b>The combined therapy of spinal balancing and the intervention of pathway of qi achieves the superior efficacy on various types of cervical spondylosis as compared with the conventional acupuncture and massage therapy. It apparently relieves the symptoms and improves the life quality of the patients.</p>

<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>
