Objective To investigate the correlation between the level of postprandial blood glucose (PBG)and the incidence of coronary artery disease(CAD). Methods Eighty-five patients performed coronary angiography with abnormal blood glucose levels were divided into 3 groups according the blood glucose levels: impaired fasting glucose(IFG)group(28 cases), impaired glucose tolerance(IGT)group(29cases)and diabetes mellitus(DM)group(28 cases). The detection rate and the extent of CAD were observed. The risk factors of CAD in 3 groups such as C-reactive protein(CRP),carotid artery intima-media thickness(CIMT), blood lipids, blood pressure, body mass index(BMI)and the correlation with CAD were analyzed. Results Sixty-two cases were confirmed CAD by coronary angiography. The incidence rate of CAD in IGT group[79.3%(23/29)]and DM group[85.7%(24/28)]was significantly higher than that in IFG group[53.6%(15/28)](P ＜ 0.01). The incidence rate of CAD in DM group was higher than that in IGT group, but there was no significant difference(P ＞ 0.05). The incidence rate of two-lesion and three-lesion in IGT group and DM group were significantly higher than those in IFG group(P＜ 0.01). The incidence rate of two-lesion and three-lesion in DM group were higher than those in IGT group, but there was no significant difference(P＞0.05). The levels of CRP, CIMT, BMI, triacylglycerol(TG)and systolic blood pressure(SBP)were higher and HDL-C was lower in IGT group and DM group than those in IFG group(P ＜ 0.01 or ＜ 0.05).The levels of CRP,TG and SBP were higher in DM group than those in IGT group(P＜0.05). Correlation analysis showed, in IGT group and DM group,2 h PG had significantly positive correlation with CRP, CIMT,B MI, TG(P＜0.05 or＜0.01), and had significantly negative correlation with HDL-C(P＜0.05 or ＜0.01).Conclusions PBG is closely related with the development of CAD.IGT patients should be intervened as early as possible, which can be effective in preventing cardiovascular events.

Objective To study the effects of asiaticoside on the growth of melanoma B16 cell cultures in vitro. Methods Melanoma B16 cells were subcultured and the inhibition of cellular growth was investigated. The morphology of the cells was observed after inhibition. The induction of apoptosis by asiaticoside was determined by flow cytometry.

Robotic-assisted transanal total mesorectal excision (R-TaTME) has unique advantage in low rectal cancer. Single incision plus oneport (SIPOP) laparoscopic operation can synchronously cooperate with robotic-assisted transanal operation, in order to the difficulty of operation, improve the quality of operation and shorten the time of operation. A retrospective analysis was conducted on the clinical and pathological data of one patient who underwent SIPOP synchronously combined with R-TaTME + sigmoid-anal anastomosis + ileostomy at the Department of General Surgery, Army Characteristic Medical Center on September 11, 2019. This 71-year-old patient was male with body mass index of 24.08 kg/m 2 and received preoperative chemotherapy. Rectal adenocarcinoma was confirmed by colonoscopy biopsy, and distance from tumor lower edge to anal verge was 3 cm. MRI indicated T2N1 stage. The operation was completed successfully, and the transabdominal and robotic transanal surgery totaled 117 minutes, with 15 minutes for the robotic transanal preparation step. There was about 20 ml of intraoperative blood loss and no blood transfusion was performed. The patient was discharged 6 days after operation. No intraoperative or postoperative complications occurred. The postoperative TNM staging was stage I (pyT2N0cM0). No recurrence or metastasis was found at postoperative 7 month. It is a safe, effective and feasible technique for patients with low rectal cancer.

Objective To explore clinical effect of distal tibial tubercle-high tibial osteotomy(DTT-HTO)in treating knee osteoarthritis(KO A)with medial meniscus posterior root tear(MMPRT).Methods A retrospective analysis was performed on 21 patients with varus KOA with MMPRT from May 2020 to December 2021,including 3 males and 18 females,aged from 49 to 75 years old with an average of(63.81±6.56)years old,the courses of disease ranged from 0.5 to 18.0 years with an average of(5.9±4.2)years,and 4 patients with grade Ⅱ,14 patients with grade Ⅲ,and 3 patients with grade Ⅳ according to Kellgren-Lawrence;14 patients with type 1 and 7 patients with type 2 according to MMPRT damage classification.The distance of medi-al meniscusextrusion(MME)and weight-bearing line ratio(WBLR)of lower extremity were compared before and 12 months after operation.Visual analogue scale(V AS),Western Ontarioand and McMaster Universities(WOMAC)osteoarthritis index,and Lysholm knee score were used to evaluate knee pain and functional improvement before operation,1,6 and 12 months after operation,respectively.Results Twenty-one patients were followed up for 12 to 18 months with an average of(13.52±1.72)months.MME distance was improved from(4.99±1.05)mm before operation to(1.87±0.76)mm at 12 months after operation(P＜0.05).WBLR was increased from(15.49±7.04)％before operation to(62.71±2.27)％at 12 months after operation(P＜0.05).VAS was decreased from(7.00±1.14)before operation to(2.04±0.80),(0.90±0.62)and(0.61±0.50)at 1,6 and 12 months after operation.WOMAC were decreased from preoperative(147.90±9.88)to postoperative(103.43±8.52),(74.00±9.54)and(47.62±9.53)at 1,6 and 12 months,and the difference were statistically significant(P＜0.05).Lysholm scores were increased from(46.04±7.34)before oepration to(63.19±8.93),(81.10±6.41)and(89.29±3.04)at 1,6 and 12 months after operation(P＜0.05).Conclusion For the treatment of varus KOA with MMPRT,DTT-HTO could reduce medial meniscus pro-trusion distance,improve the ratio of lower limb force line,and effectively reduce knee pain and improve knee joint function.

Objective: To investigate the feasibility of transumbilical single-incision plus one port (SIPOP) robotic total mesorectal excision. Methods: Clinical data of a 70-year-old male patient with BMI 22.1 kg/m(2) who successfully underwent transumbilical single-incision plus 1 port robotic total mesorectal resection of upper rectal cancer at the General Surgery Department of Daping Hospital of Army Military Medical University on September 18, 2019 were retrospectively analyzed. Preoperative colonoscopy revealed that the distance of upper rectal cancer to anal edge was 14 cm, and the tumor size was 2.5 cm×1.5 cm×1 cm. Pathological result confirmed rectal moderately differentiated adenocarcinoma. The preoperative abdominal CT showed thickened bowel-wall of upper rectum and the blurred perirectal fat, suggesting tumor infiltration. Results: The operation was successful. There were no conversion to laparotomy or abdominal auxiliary incision, and the mesorectum of the specimen was intact. The operation time was 165 minutes, the blood loss was about 20 ml, and there were no complications such as injury to peripheral organs. Postoperative pathology showed ulcerative moderately differentiated adenocarcinoma of the upper rectum with TNM stage IVA (T4N2b). The postoperative recovery was smooth. Patient ambulated on the 1st day, the catheter was removed on the 7th day, and discharged from the hospital on the 8th day. Conclusion: The transumbilical SIPOP robotic total mesorectal excision is safe, effective and feasible.

OBJECTIVETo analyze the clinical characteristics of three Chinese cases of Niemann-Pick disease type C patients with neonatal cholestasis as initial presentation, and enhance awareness of Niemann-Pick disease type C among pediatricians.

METHODThree sporadic cases with confirmed Niemann-Pick disease type C initially presented as neonatal cholestasis were retrospectively reviewed in this study. Their peripheral blood specimens were collected after obtaining informed consent. All exons and the intron-exon boundaries of NPC1 gene were examined by bi-directional sequencing.

RESULTThree patients, 1 female and 2 males, aged from 2 months to 5 years and 10 months, all first complained of jaundice in the neonatal period. Laboratory tests showed total bilirubin and direct bilirubin significantly increased with predominant increase of direct bilirubin. Total bile acid, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were also increased, while high-density lipoprotein cholesterol decreased. All patients were also accompanied by hepatosplenomegaly, with two of them having increased bronchovascular markings in chest X-ray. Two heterozygous changes of NPC1 gene, c.2741G>T +c.3020C>G (p. C914F + p. P1007R), c.2177G>C + c.3734_ 3735delCT (p.R726T + p. P1245RfsX12), and c.2054T>C + c.2128C>T(p.I685T + p.Q710X), were identified in patient 1, 2 and 3, respectively.

CONCLUSIONWe reported three cases suffered from Niemann-Pick disease type C with initial presentation as neonatal cholestasis in the mainland of China. For newborns with prolonged jaundice in the neonatal period, as well as neonatal cholestasis, hepatosplenomegaly, Niemann-Pick type C should be included in consideration of differential diagnosis. Genetic testing can identify causative mutations for diagnosis.

OBJECTIVETo analyze the clinical characteristics of the patient with tyrosine hydroxylase deficiency, and investigate it's molecular mechanism.

METHODThe clinical characteristics of a patient with tyrosine hydroxylase deficiency were summarized and analyzed, his and his family's peripheral blood specimens were collected after informed consent was signed. All exons and the intron-exon boundaries of guanosine triphosphate hydroxylase I gene, tyrosine hydroxylase gene and sepiapterin reductase gene were examined by DNA-PCR, bi-directional sequencing.

RESULTThe patient was a 3-year-old boy, presented with unexplained dystonia for 3 years, without significant impairment of intelligence. Physical examination showed limb muscle strength grade V, rigidity of extremities, hypertonicity, brisk deep tendon reflexes in limbs, without obvious abnormalities in auxiliary examination, such as brain MRI, hepatic biochemical panel, creatine kinase, and ceruloplasmin. He dramatically responded to small doses of levodopa in the follow-up for half a year. A homozygous missense change in exon 5 of TH gene, c.605G > A (p.R202H), which was a known pathogenic mutation, was found in the patient. His parents were heterozygous for the R202H mutation.

CONCLUSIONThe age of onset in tyrosine hydroxylase deficiency patients is usually within the first year of life. Unexplained dystonia and hypokinesia were the main clinical features of tyrosine hydroxylase deficiency. The dopa-responsive effects for some patients are so obvious that we should strengthen awareness of the disease. TH gene c.605G > A (p.R202H) may be a common type of causative mutations for the mild form at home and abroad.
