Objective The leptin receptor,encoded by the LEPR gene,is involved in tumorigenesis.A potential functional variant of LEPR,rs1137101(Gln223Arg),has been extensively investigated for its contribution to the risk of digestive system(DS)cancers,but results remain conflicting rather than conclusive.Here,we performed a case-control study and subsequent meta-analysis to examine the association between rs1137101 and DS cancer risk. Methods A total of 1,727 patients with cancer(gastric/liver/colorectal:460/480/787)and 800 healthy controls were recruited.Genotyping of rs1137101 was conducted using a polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)assay and confirmed using Sanger sequencing.Twenty-four eligible studies were included in the meta-analysis. Results After Bonferroni correction,the case-control study revealed that rs1137101 was significantly associated with the risk of liver cancer in the Hubei Chinese population.The meta-analysis suggested that rs1137101 is significantly associated with the risk of overall DS,gastric,and liver cancer in the Chinese population. Conclusion The LEPR rs1137101 variant may be a genetic biomarker for susceptibility to DS cancers(especially liver and gastric cancer)in the Chinese population.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective The relationship between parasitic infections and cancer has become a research hotpot.Although reports of single intestinal protozoan infection in gastrointestinal cancer patients,co-infections are rare.To investigate co-infections of intestinal protozoa in gastrointestinal cancer patients.Methods The DNA of 195 fecal specimens was amplified using nested PCR and sequenced for the presence of Pentatrichomonas hominis,Giardia duodenalis,Cryptosporidium parvum,Blastocystis hominis,Dientamoeba fragilis,and Enterocytozoon bieneusi.Results An overall infection rate of 48.72％(95/195),with 23 cases(24.21％)co-infected with two parasites,three cases(3.16％)co-infected with three parasites.Additionally,67 cases(70.52％)were infected with one protozoa,including 56 cases with Pentatrichomonas hominis,one with Blastocystis hominis,nine with Cryptosporidium parvum,and one case with Dientamoeba fragilis.No infection with Enterocytozoon bieneusi was detected.Conclusion The results indicated a high rate of intestinal protozoan co-infection among gastrointestinal cancer patients.Through one-way ANOVA analysis,it was observed that cases of individual infection with P.hominis were significantly higher compared to those of co-infection with two or three types of protozoa containing P.hominis(P=0.0022)and cases of co-infection with three types of protozoa(P=0.0019).However,no significant difference in the infection rates was observed between two and three types of protozoa(P=0.2775),suggesting that cases of single infection with P.hominis were higher than cases of co-infection with two or more types of protozoa in gastrointestinal cancer patients.BLAST and single nucleotide polymorphism analysis revealed that gene sequences of different infected protozoa,except for a few with 100％homology to the GenBank reference sequence,exhibited varying degrees of base mutations,insertions,or loss at different loci.This study offers crucial insights for understanding the etiology,diagnosis,and prevention of gastrointestinal cancer.

OBJECTIVE: To evaluate the efficacy and safety of Jianpi Jieyu Decoction (JJD) for treating patients with mild-to-moderate depression of Xin (Heart)-Pi (Spleen) deficiency (XPD) syndrome. METHODS: In this multi-center, randomized, controlled study, 140 patients with mild-to-moderate depression of XPD syndrome were included from Xiyuan Hospital of China Academy of Chinese Medical Sciences and Botou Hospital of Traditional Chinese Medicine from December 2017 to December 2019. They were randomly divided into JJD group and paroxetine group by using a random number table, with 70 cases in each group. The patients in the JJD group were given JJD one dose per day (twice daily at morning and evening, 100 mL each time), and the patients in the paroxetine group were given paroxetine (10 mg/d in week 1; 20 mg/d in weeks 2-6), both orally administration for a total of 6 weeks. The primary outcome was the change of 17-item Hamilton Depression Rating Scale (HAMD-17) score at week 6 from baseline. The secondary outcomes included the Hamilton Anxiety Scale (HAMA) score, Traditional Chinese Medicine Symptom Scale (TCMSS), and Clinlcal Global Impression (CGI) scores at the 2nd, 4th, and 6th weekends of treatment, HAMD-17 response (defined as a reduction in score of >50%) and HAMD-17 remission (defined as a score of ⩽7) at the end of the 6th week of treatment. Adverse events (AEs) were also recorded. RESULTS: From baseline to week 6, the HAMD-17 scores decreased 10.2 ± 4.0 and 9.1 ± 4.9 points in the JJD and paroxetine groups, respectively (P=0.689). The HAMD-17 response occurred in 60% of patients in the JJD group and in 50% of those in the paroxetine group (P=0.292); HAMD-17 remission occurred in 45.7% and 30% of patients, respectively (P=0.128). The differences of CGI scores at the 6th week were not statistically significant (P>0.05). There were significant differences in HAMD-17 scores between the two groups at 2nd and 4th week (P=0.001 and P=0.014). The HAMA scores declined 8.1 ± 3.0 and 6.9 ± 4.3 points from baseline to week 6 in the JJD and paroxetine groups, respectively (P=0.905 between groups). At 4th week of treatment, there was a significant difference in HAMA between the two groups (P=0.037). TCMSS decreased 11.4 ± 5.1, and 10.1 ± 6.8 points in the JJD and paroxetine groups, respectively (P=0.080 between groups). At the 6th week, the incidence of AEs in the JJD group was significantly lower than that in the paroxetine group (7.14% vs. 22.86%, P<0.05). CONCLUSION Compared with paroxetine, JJD was associated with a significantly lower incidence of AEs in patients with mild-to-moderate depression of XPD syndrome, with no difference in efficacy at 6 weeks.

AIM: To evaluate retinal vascularization caused by the intravitreal injection of Conbercept in the treatment of a series of retinopathy of prematurity(ROP)cases in Type Ⅰ(threshold and pre-threshold period)and aggressive ROP(A-ROP).METHODS: The data of 34 ROP cases(67 eyes)treated by intravitreal injection of Conbercept(IVC)in the ophthalmology department of the Xiamen Children's Hospital from July 2017 to March 2020 were retrospectively analyzed. Reactivation, which refers to recurrence of acute phase features, occurred at any stage of the disease in the presence or absence of other diseases. RESULT: The average gestational age of the 34 children was 28.82±2.32wk. The average birth weight was 1155.18±398.22g. The lesion zone of 19 cases(37 eyes)was Zone Ⅰ. In 10 cases(20 eyes), the lesion was in Zone Ⅱ, and in 5 cases(10 eyes), the lesion was in the posterior Zone Ⅱ. The total effective rate of disease control in ROP children treated with once IVC was 73.1%(49/67), and the vascularization of Zone Ⅱ was completed. The patients showed variable changes in the vascularization in Zone Ⅲ. For the patients who received one treatment and did not reactivate, the average rate of Type Ⅰ vascularization of ROP was 9.11±2.49wk, and the A-ROP was 13.40±4.04wk. The rate of A-ROP vascularization in Zone Ⅱ was significantly longer compared to Type Ⅰ.CONCLUSION: IVC effectively completes vascularization in Zone Ⅱ.

Compound 1 is a novel macrocyclic flavonoid, and all the others are reported from this plant for the first time. In vitro cytotoxic activities of compounds 1-7 were evaluated by MTS testing with five cancer cell lines. Compound 7 exhibited weak cytotoxicity against tumor cell lines A549, SMMC-7721, and SW480.

Different from other trauma, the scar and pigmentation formed after healing of burn wound not only hinder beauty but also easily lead to a series of sequential psychological problems, such as depression and anxiety. Music therapy, as a supplementary treatment, is widely used in many fields including medical and health care and psychological regulation. However, affected by factors such as medical resources, the awareness and acceptance of music therapy among burn treatment workers in China are still low. Based on the clinical characteristics of burns, this paper matches the applicability of music therapy with it, summarizes the supplementary application of music therapy in the field of burn treatment, expounds this natural science with both science and aesthetics, and puts forward feasible suggestions for its future development.

OBJECTIVE: To assess the efficacy and safety of mulberry twig alkaloids (Sangzhi alkaloids, SZ-A) for treatment of type 2 diabetes in a randomized, double-blind, placebo-controlled multicenter clinical trial. METHODS: A total of 200 patients were randomized to receive SZ-A (n=100) or placebo (n=100) for 16 weeks. The data analysis system for electronic data capture clinical trial central randomization system was used for randomization and dispensing of drugs. The primary outcome was the change in glycosylated hemoglobin (HbA1c) level. The secondary outcome included the proportions of cases with HbA1c <7.0% and HbA1c <6.5%, fasting blood glucose (FBG), postprandial blood glucose (PBG), area under curve for the PBG (AUC_0-2h), body weight, and body mass index (BMI). Adverse events (AEs), severe adverse events (SAEs), treatment-related adverse events (TAEs), gastrointestinal disorders (GDs), blood pressure, routine blood tests, and liver and kidney function were monitored. RESULTS: Compared with baseline, the change of HbA1c at week 16 was -0.80% (95% CI: -0.98% to -0.62%) and -0.09% (95% CI: -0.27% to 0.09%) in SZ-A group and placebo group, respectively. The proportion of patients with HbA1c <7% and <6.5% was higher in the SZ-A group than in the placebo group (46.8% vs. 21.6% and 29.9% vs. 10.8%). The observed values and changes in FBG, 1 h-PBG, 2 h-PBG, and AUC_0-2h differed significantly between groups (P<0.001), but differences were not significant in body weight and BMI (P>0.05). The incidence rates of AEs, TAEs, and GDs differed significantly between groups (P=0.010, P=0.005, and P=0.006, respectively), whereas the incidence rates of SAEs showed no significant differences between groups (P=1.000). CONCLUSION SZ-A are effective and safe for treatment of type 2 diabetes. The protocol was registered in http://www.chictr.org.cn/showproj.aspx?proj=60117 (ChiCTR2000038550).

The study investigates the mechanism by which Peganum harmala L. (Luotuopeng, LTP) inhibits tube formation in retinal vascular endothelial cells. Tube formation was induced by treatment of retinal vascular endothelial cells with glucose. The cells were divided into a normal group, model group, and an LTP group. The total length of tube formation was measured. The active components, targets, and pathway by which LTP acts in the treatment of diabetic retinopathy was explored by network pharmacology. The mRNA expression levels of targets [extracellular signal-regulated kinase 2 (ERK2), phosphoinositide 3 kinase catalytic alpha polypeptide (PIK3CA), serine/threonine-protein kinase 1 (AKT1)] related to the mitogen-activated protein kinase (MAPK) signaling pathway and vascular endothelial growth factor (VEGF) signaling pathway was measured by real-time PCR. The results of tube formation indicated that compared with the normal group, the total tube length increased in the model group (P < 0.01); after the treatment with LTP, the total tube length decreased compared with the model group (P < 0.01). Network pharmacology revealed that the targets of LTP included PIK3CA, AKT1, and ERK2, and the pathways involved the MAPK signaling pathway and the VEGF signaling pathway. Real-time PCR indicated that compared with the normal group, the mRNA expression levels of ERK2, PIK3CA and AKT1 were elevated in the model group (P < 0.05); after treatment with LTP, the mRNA expression levels of ERK2, PIK3CA and AKT1 decreased compared with the model group (P < 0.05). LTP may inhibit retinal vascular endothelial cell tube formation by regulating the MAPK signaling pathway and the VEGF signaling pathway. This study confirms the multi-targets and multi-pathways of LTP and provides a basis for its use in the treatment of diabetic retinopathy．

Objective:To analyze the source of infection， clinical symptoms and epidemiological characteristics of pertussis surveillance cases in Minhang District of Shanghai from 2017 to 2019，so as to provide the basis for pertussis surveillance and immunization strategy. Methods:Descriptive epidemiological method was used to analyze the pertussis surveillance cases. Results:A total of 334 cases were included in the pertussis active surveillance system， 237 cases were confirmed cases. There were 13 towns or streets in Minhang District， except for Pujin Street， all the other 12 towns or streets had cases. The high risk group （131/237， 55.27% of the cases） were the infants under five months old who did not reach the age of immunization or did not complete the basic immunization of diphtheria， tetanus， and acellular pertussis combined vaccine （DTaP）. The cases mainly occurred in March to July， accounting for 71.31% （169/237）. The highest culture-positive rate of Bordetella pertussis was in August （82.76%， 24/29）； the highest positive rate of polymerase chain reaction （PCR） detection was in March （58.82%， 20/34）. All the monitored cases had cough symptoms with an average cough days of 22.05±9.81 in confirmed cases. A total of 64 clustered outbreaks were detected， with an attack rate of 37.45% （94/251）. 32.91% （78/237） of the cases had contact history with coughing patients 21 days before the onset， and 94.87% （74/78） of them were family members. The aggregation of pertussis was mainly transmitted from adults to infants and infants to adults. Conclusion:Children under five months old are the high incidence population of pertussis， and family members are the main source of infection. It is suggested that pertussis monitoring and prevention should be carried out in adolescents and adults.
