Objective To investigate the effect and mechanism of Shuangzhu Kangxian Prescription(Astragali Radix,bran-fried Atractylodis Macrocephalae Rhizoma,vinegar-prepared Rhizoma Curcumae,Bupleuri Radix,Salviae Miltiorrhizae Radix et Rhizoma,Litchi Semen)on improving hepatitic fibrosis induced by carbon tetrachloride(CCl4)in rats based on the Wnt/β-catenin signaling pathway.Methods The rat model of hepatitic fibrosis was replicated by subcutaneous injection of 3.0 mL·kg-1 40%CCl4 twice a week for 8 weeks.SD rats were randomly divided into blank control group(n=8),model group(n=7),positive control group(n=7,intragastric administration of 43.19 mg·kg-1 silymarin),low-dose Chinese medicine group(n=6,intragastric administration of 4.3 g·kg-1Shuangzhu Kangxian Prescription),medium-dose Chinese medicine group(n=6,intragastric administration of 8.6 g·kg-1Shuangzhu Kangxian Prescription),high-dose Chinese medicine group(n=7,intragastric administration of 17.2 g·kg-1Shuangzhu Kangxian Prescription).The continuous intragastric administration was given once a day for 4 consective weeks,in addition to the blank control group,the other groups continued to be subcutaneously injected with CCl4 at the same time.The pathological changes of liver tissue were observed by HE and Masson staining.The levels of serum type Ⅳ collagen(Col Ⅳ),type Ⅲ procollagen(PC Ⅲ),hyaluronic acid(HA)and laminin(LN)were detected by ELISA.The protein expression levels of Wnt1,β-catenin and PPAR-γ in liver tissue were detected by Western Blot.The mRNA expression levels of Wnt1,β-catenin and PPAR-γ in liver tissue were detected by qPCR.Results Compared with the blank control group,the liver of the model group showed partial necrosis of liver cells,the normal hepatic lobule structure was destroyed,the arrangement of liver cell cords was disordered,the central vein or portal area was enlarged,and a large number of inflammatory cells infiltrated to form bridging necrosis.The collagen fibers in the central vein or portal area of the liver proliferated significantly,forming fibrous septa,and the fibrosis score were significantly increased(P＜0.05).The levels of serum Col IV,PC Ⅲ,HA and LN were significantly increased(P＜0.05).The protein and mRNA expression levels of Wnt1 and β-catenin in liver tissue were significantly increased(P＜0.05),and the protein and mRNA expression levels of PPAR-γ were significantly decreased(P＜0.05).Compared with the model group,the steatosis of hepatocytes in the positive control group and the medium-and high-dose groups of Chinese medicine was improved,and the necrosis and inflammatory cell infiltration were reduced.The degree of hepatitic fibrosis was improved,the liver collagen fibers were reduced,and the fibrosis score was significantly reduced(P＜0.05).The levels of serum Col Ⅳ,PC Ⅲ,HA and LN were significantly decreased(P＜0.05).The protein and mRNA expression levels of Wnt1 and β-catenin in liver tissue were significantly decreased(P＜0.05),and the protein and mRNA expression levels of PPAR-γ were significantly increased(P＜0.05).Conclusion Shuangzhu Kangxian Prescription has the effect of anti CCl4-induced hepatitic fibrosis in rats,and its mechanism may be related to the inhibition of Wnt/β-catenin signaling pathway and up-regulation of PPAR-γ expression.

Objective: To analyze the influencing factors and physical and mental development of preschool children with iron deficiency anemia in Dongguan, so as to provide a reference for the prevention of iron deficiency anemia among preschool children. Methods: A total of 118 preschool children with iron deficiency anemia who were examined in Dongguan Maternal and Child Health Center from January 2022 to December 2022 were enrolled in the anemia group, and 118 preschool healthy children who were examined in the hospital at the same time were enrolled in the control group. The physical and mental development of the children were evalucded in both groups. Demographic information and household per capita income were collected. The relationship between risk factors and iron deficiency anemia was analyzed by univariate analysis and multiple Logistic regression. Results: The scores of fine motor skills, gross motor skills, adaptability, social communication, language ability and developmental quotient of children in anemia group were significantly lower than those in control group ( t =4.14, 5.46, 5.60, 5.50, 4.90, 5.83, P <0.01). The difference in scores of adaptability, fine motor skills, gross motor skills language ability, social communication and developmental quotient between the two groups increased with age ( F =390.56, 414.63, 437.35, 409.68, 407.20, 404.54, P < 0.05 ). Multivariate Logistic regression analysis showed that household income, history of past digestive disease, gestational age, maternal anemia during pregnancy, maternal education, consumption of meat, eggs and milk, and intake of nuts were all associated with iron deficiency anemia among preschool children in Dongguan ( OR =2.23，2.99，3.99，3.56，3.11，1.68，1.61, P < 0.05 ). Conclusion The physical and mental development of preschool children with iron deficiency anemia in Dongguan is slower than that of non anemia children of the same age, and the development delay becomes more obvious with increasing age. Attention should be paid to the prevention of iron deficiency anemia among preschool children. It is important to provide reasonable dietary guidance for children with high risk factors such as digestive disease history and prematurity.

ObjectiveTo study the effect of total flavone of Litchi Semen （TFL） on proliferation， apoptosis， migration， and invasion of hepatoma cells HepG2. MethodMethyl thiazolyl tetrazolium colorimetric （MTT） assay was used to detect the effect of different-dose TFL and cisplatin on the proliferation of HepG2 cells. TdT-mediated dUTP nick-end labeling （TUNEL） assay was used to detect the effects of low， medium， and high-dose （70， 140， 210 mg·L^-1） of TFL and cisplatin （60 mg·L^-1） on the apoptosis of HepG2 cells， thus selecting the optimal dose of TFL for the follow-up experiment. HepG2 cells were divided into a blank group， a TFL group （140 mg·L^-1）， a TFL+XL019 group （140 mg·L^-1 TFL+0.5 μmol·L^-1 XL019）， and a TFL+TPI-1 group （140 mg·L^-1 TFL+1 μmol·L^-1 TPI-1）. The effect of TFL on migration and invasion of HepG2 cells were examined by wound healing test and Transwell invasion assay， and the effect of TFL on the expression of epithelial-mesenchymal transition （EMT） marker in HepG2 cells were examined by cell immunofluorescence assay. Western blot was used to detect the expression of key proteins in Janus kinase 2（JAK2）/signal transducer and activator of transcription 3 （STAT3） signaling pathway after the intervention by TFL. ResultMTT assay showed that the proliferation of HepG2 cells was significantly inhibited by TFL and cisplatin at 24 and 48 h as compared with blank group （P<0.01）， and the half maximal inhibitory concentration （IC₅₀） of TFL on HepG2 cells was （136.7±2.40） mg·L^-1 at 24 h and （106.8±1.11） mg·L^-1 at 48 h. The IC₅₀ of cisplatin on HepG2 cells was （58.48±2.04） mg·L^-1 at 24 h and （5.15±0.56） mg·L^-1 at 48 h. The results of TUNEL assay showed that TFL induced apoptosis of HepG2 cells. The optimal dose of TFL was 140 mg·L^-1. The results of wound healing test showed that compared with the blank group， the TFL group， TFL+XL019 group， and the TFL+TPI-1 group significantly inhibited the migration of HepG2 cells （P<0.05， P<0.01）. As compared with the TFL group， the inhibitory effect of the TFL+XL019 Group was significantly increased （P<0.05）， while that of the TFL+TPI-1 group was significantly decreased （P<0.01）. The Transwell invasion assay showed that compared with the blank group， the TFL group， TFL+XL019 group， and the TFL+TPI-1 group significantly inhibited the invasion of HepG2 cells （P<0.01）. As compared with the TFL group， the inhibitory effect of the TFL+XL019 group was significantly increased （P<0.05）， while that of the TFL+TPI-1 group was significantly decreased （P<0.01）. The results of immunofluorescence showed the intervention of TFL up-regulated the expression of E-cadherin， and down-regulated the expression of Vimentin in HepG2 cells， which was stronger in the TFL+XL019 group and weaker in the TFL+TPI-1 group. The results of Western blot showed that compared with the blank group， the TFL group， TFL+XL019 group， and the TFL+TPI-1 group did not affect the expression of JAK2 or STAT3 protein， but significantly decreased the expression levels of phosphorylatied （p）-JAK2 and p-STAT3 （P<0.05， P<0.01）. As compared with the TFL group， the expression levels of p-JAK2 and p-STAT3 in the TFL+XL019 group were significantly decreased （P<0.01）， while those in the TFL+TPI-1 group were significantly increased （P<0.01）. Compared with the blank group， the TFL group significantly increased the expression level of Src-homology domain 2 containing protein tyrosine phosphatase-1（SHP-1） with sh2 domain （P<0.01）. ConclusionTFL has the effects of inhibiting the proliferation， promoting apoptosis of HepG2 cells， and reversing the EMT process of HepG2 cells to reduce the migration and invasion， which are presumably related to the activation of SHP-1 by TFL to block JAK/STAT3 signaling pathway.

Objective:To investigate the feasibility and clinical efficacy of laparoscopic radical cholecystectomy(LRC) for gallbladder cancer.Methods:The clinical data of 247 patients with gallbladder cancer who underwent radical resection from Jan 2013 to Dec 2019 at Department of General Surgery, Sir Run Run Shaw Hospital affiliated to Zhejiang University School of Medicine was analyzed retrospectively. After propensity score matching, 54 patients were included in laparoscopic group and 103 in laparotomy group. The clinicopathological characteristics and the short- and long-term outcomes were compared.Results:Compared to the laparotomy group, patients in the laparoscopic group had less intraoperative blood loss [100(50,200)ml vs. 200(100,300) ml, Z=4.105, P<0.001], earlier postoperative oral diet[1.0(1.0,2.0) d vs. 2.0(1.0,4.0) d, Z=4.157, P<0.001]and drainage removal[6.5(4.0,12.5) d vs. 9.0(6.0,16.0) d, Z=2.769, P=0.006], shorter hospital stay[7.0(5.0,9.3) d vs. 9.0(8.0,14.0) d, Z=3.923, P<0.001]. The number of lymph node dissection in laparoscopic group was significantly lesser than that in open group [6(4,9) vs. 8(5,12), Z=2.639, P=0.008]. There were no significant differences between the two groups in postoperative complications, short-term and long-term survival outcomes. Conclusions:Laparoscopic radical surgery for gallbladder cancer is as safe and feasible, and identical survival prognosis as open surgery, and moreover a less traumatic procedure.

Background and objective As computed tomography (CT) screening for lung cancer becomes more common in China, so too does detection of pulmonary ground-glass nodules (GGNs). Although anumber of national or international guidelines about pulmonary GGNs have been published,most of these guidelines are produced by respiratory, oncology or radiology physicians, who might not fully understand the progress of modern minimal invasive thoracic surgery, and these current guidelines may overlook or underestimate the value of thoracic surgery in the management of pulmonary GGNs. In addition, the management for pre-invasive adenocarcinoma is still controversial. Based onthe available literature and experience from Shanghai Pulmonary Hospital, we composed this consensus about diagnosis and treatment of pulmonary GGNs. For lesions which are considered as adenocarcinoma in situ, chest thin layer CT scan follow-up is recommended and resection can only be adopt in some specific cases and excision should not exceed single segment resection. For lesions which are considered as minimal invasive adenocarcinoma, limited pulmonary resection or lobectomy is recommended. For lesions which are considered as early stage invasive adenocarcinoma, pulmonary resection is recommend and optimal surgical methods depend on whether ground glass component exist, location, volume and number of the lesions and physical status of patients. Principle of management of multiple pulmonary nodules is that primary lesions should be handled with priority, with secondary lesions taking into account.

Objective: To investigate the expression of long non-coding RNA NUP50-AS1 (lncRNA NUP50-AS1) in esophageal squamous cell carcinomas (ESCC) tissues and cell lines, and to explore its effect on proliferation, migration and invasion of human esophageal cancer Eca109 cells. Methods: 49 pairs of ESCC tissues and corresponding para-cancerous tissues obtained from the Biological Specimen Base of the Fourth Hospital of Hebei Medical University during Jan. 2015 to Jan. 2016 were used in this study. qRT-PCR method was applied to detect the expression of NUP50-AS1 in collected tissues samples and five esophageal cancer cell lines (TE1, TE13, Eca109, Kyse150 and Kyse170). ShRNAs were transiently transfected into Eca109 cells to interfere the expression of NUP50AS1 gene, and finally, sh2-NUP50-AS1 was used for the following experiments. The effect of NUP50-AS1 gene knockdown on the proliferation of Eca109 cells was detected by MTS and colony formation assay; the effect of NUP50-AS1 gene knockdown on the migration of Eca109 cells was detected by scratch test, and the effect on cell invasion was detected by Transwell assay. Results: The expression of NUP50-AS1 in ESCC was correlated with the lymphnode metastasis and TNM stage (all P<0.01). The expression of NUP50AS1 in ESCC tissues was significantly higher than that in corresponding normal tissues (2.003±0.870 vs 1.000±0.000, P<0.05). The expression of NUP50-AS1 in five esophageal cancer cell lines was significantly up-regulated (P<0.05), and it had the highest expression in Eca109 cell line. After transfection, sh2-NUP50-AS1 had the highest transfection efficiency, and knocking down NUP50-AS1 gene significantly inhibited the proliferation, invasion and migration of the Eca109 cells. Conclusion: The expression of lncRNA NUP50AS1 in ESCC tissues was significantly higher than that in the para-cancerous tissues, and correlated with the TNM stage and lymphnode metastasis. The down-regulation of NUP50-AS1 inhibited the proliferation, invasion and migration of esophageal cancer cells. The high expression of NUP50-AS1 gene may be closely related to the occurrence and development of ESCC.

Objective To sequence and analyze the near full-length genome of an HIV-1 subtype G strain identified in Guangxi,China.Methods The demographic information of an individual infected with HIV-1 subtype G strain was investigated,whose peripherial blood was collected.Viral RNA in plasma was extracted.The near full-length genome of HIV was amplified in two halves using RT-nested-PCR.The PCR products were purified and sequenced.Phylogenetic analysis was made using MEGA6 software.Results A near full-length genome of 8847 bp was obtained.In the neighbor-joining tree,the strain clustered with subtype G references,as supported by the high Bootstrap value (100%).The closest phylogenetic relationship was found between our strain and another subtype G strain (JN106043)previously identified in Guangxi,which was supported by the genetic distance (5%)and high Bootstrap value (100%).Conclusion The strain identified in the study might have originated from subtype G strains in Guangxi,suggesting that subtype G has spread locally in Guangxi.Further surveillance of subtype G epidemic in Guangxi is necessary.The near full-length subtype G strain genome will provide information for the surveillance of HIV in Guangxi.
