Correlation analysis of serum lipids, HbA1C levels and insulin resistance in obese type 2 diabetes patients / 公共卫生与预防医学

Objective To investigate the changes of blood lipid and glycosylated hemoglobin (HbA1c) levels in obese type 2 diabetes (T2DM) patients and their relationship with insulin resistance (Homa-IR). Methods A total of 120 cases of T2DM newly diagnosed in Motuo County, Tibet from February to October 2022 were selected as the observation group. According to BMI, the patients were divided into diabetes normal weight group (46 cases), overweight group (43 cases) and obesity group (31 cases); 145 healthy subjects were selected as the control group. The levels of HbA1c, fasting blood glucose (FPG), fasting insulin (FINS), serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL-C), and low-density lipoprotein (LDL-C) were detected in the study subjects, and Homa-IR and Homa-β indices were calculated. The height, weight, and abdominal circumference were measured. The differences in the levels of the above indicators between the observation group patients and the control group, as well as among various subgroups within the observation group were compared. The influencing factors of Homa-IR in obese T2DM patients were analyzed. Results Compared with the control group, a significant increase in BMI, abdominal circumference, blood pressure, HbA1c, FBG, FINS, TC, TG, LDL-C, UA, visceral fat area, and the levels of Home-IR and Home-β was found in the observation group (all P<0.05). There were significant differences in BMI, abdominal circumference, and the levels of FINS, Homa IR, Homa-β, and HbA1c in diabetes patients with different BMI (all P<0.05). Correlation analysis showed that TG levels in obese T2DM patients in the observation group were significantly correlated with HbA1c (r=0.396, P=0.027), Homa-IR (r=0.405, P=0.024), and Home-β (r=-0.401, P=0.025); LDL-C was significantly correlated with Homa-IR (r=0.411, P=0.022) and Homa-β (r=-0.412, P=0.021); HbA1c was significantly positively correlated with BMI (r=0.371, P=0.040). Conclusion Insulin resistance is closely related to TG, LDL-C, and BMI in obese T2DM patients from the Motuo ethnic minority of Tibet, suggesting that these factors may play a role in the occurrence of T2DM.

Prevention of portal venous system thrombosis after splenectomy and devasculation / 中华肝胆外科杂志

Objective To investigate the causes and prevention measures for patients with portal hypertension hypersplenism undergone splenectomy plus pericardial devascularization and post-operative portal vein thrombosis (portal vein thrombogenesis,PVT).Methods 178 cases of splenectomy plus devascularization from July 2013 to May 1994 in Cangzhou Central Hospital of Hebei Province,including 102 cases of early postoperative application of low molecular heparin anticoagulant for the prevention group,76 cases without anticoagulant medicine as control group.33 cases with PVT found by B ultrasound or CT scan,were treated with urokinase body intravenous thrombolysis,hepatic artery catheterization thrombolysis,intestinal resection of + Fogarty catheter embolectomy vein stump treatment respectively.Results The total incidence of thrombosis was 18.5％ (33/178),prevention group was 8.8％ (9/102),including 7 cases in grade Ⅰ,Ⅲ,Ⅳ thrombus,in 1 cases,no intestine necrosis.The control group thrombosis rate was 31.6％ (24/76),including 7 cases in grade Ⅰ,Ⅲ,Ⅳ,thrombosis in 17 cases,5 cases of intestine necrosis,two groups of thrombosis rate were significantly differences (x2 =14.932,P =0.000).Thrombus disappeared completely in 7 cases,the thrombus grading decreased in 2 cases in the preventive group after thrombolysis,and thrombus disappeared completely in 6 cases,11 cases of thrombosis degraded in the control group after treatment of thrombolysis,1 case cured by TIPS with thrombolysis and thrombectomy,1 case died of sudden digestive tract bleeding,Among 5 cases of intestinal necrosis,4 cases died and 1 case undergone abdominal exploration being found with intestine & colon necrosis.Conclusions There are a variety of factors causing PVT after splenectomy and devascularization.Early anticoagulation can significantly reduce the incidence of PVT,early discovery and treatment can prevent severe outcome.

Establishment of a digital model of juxtahepatic vena cava / 中华消化外科杂志

Objective To investigate the feasibility of establishing a digital model of juxtahepatic vena cava.Methods The clinical data of 120 participants (without liver diseases) who were admitted to the Cangzhou Central Hospital from January 2013 to May 2013 were collected.The results of computed tomography were analyzed.The diameters of juxtahepatic vena cava on different levels (P1 plane:inferior vena cava at the entrance to the right atrium,P2 plane:the upper margin of the roots of hepatic veins,P4 plane:lower boundary of liver,P5 plane:confluence of renal veins and inferior vena cava),and the circumference of the inferior vena cava and the lengths between these levels were recorded.A digital model of juxtahepatic vena cava was established by these data on the premise that the juxtahepatic vena cava was engorged.All data were analyzed using the analysis of variance,paired sample t test and independent samples t test,and correlation and regression were used in analysis of relations between there data.Results Data of the P1 plane and P2 plane were both missed in 3 cases,and the data of the P4 plane was missed in 8 cases.The theoretical diameter of hepatic vena cava at the P1,P2 and P4 planes were (28.1 ± 4.0) mm,(28.7 ± 3.5) mm and (23.5 ± 2.7) mm,respectively.The median diameter of hepatic vena cava at the P5 plane was 24.3 mm.The juxtahepatic vena cava was a 3 dimensional structure of cylinder with a slightly protruding middle part.There were significant differences in P1D-P2D,P2D-P4D,P1D-P4D (F =77.5,P ＜ 0.05).There were significant differences between P2D-P4D and P1D-P4D (t =14.893,11.210,P ＜ 0.05).The median length of hepatic vena cava between P1 and P2 planes was 7.5 mm.The lengths of hepatic vena cava between P1 and P4 planes,P2 and P4 planes were (85.2 ± 11.0)mm and (78.2 ±9.8)mm,respectively.The median length of hepatic vena cava between the P4 and P5 planes was 10.0 mm.P1D-P2D,P2D-P4D,P2D-P5D and P4D-P5D were positively correlated (r =0.862,0.308,0.186,0.788,P ＜ 0.05),while P1D-P4D and P2D-P5D did not correlated (r =0.180,0.118,P ＞0.05).P2D was correlated with the body weight,and P5 D was correlated with the age (r =0.200,0.130,P ＜ 0.05).The P1 D,P2D,P4D and P5 D of the inferior vena cava were (28.5 ± 3.7) mm,(29.0 ± 3.4) mm,(23.9 ± 2.8) mm and (24.3 ± 2.6) mm in males,and (27.8 ±4.2) mm,(28.5 ± 3.6) mm,(23.1 ± 2.5) mm and 24.0 mm in females.There were no significant difference in P1D,P2D,P4D and P5D between males and females (t =0.911,0.809,1.588,1.902,P ＞ 0.05).The length between P1 and P2 planes was negatively correlated with P1D and P2D (r =-0.245,-0.160,P ＜ 0.05),while the length between P4 and P5 planes was positively correlated with P1D (r =0.149,P ＜ 0.05).The length between P2 and P4 planes was positively correlated with P2D (r =0.195,P ＜ 0.05).The length between P1 and P2 planes did not correlated with the age,height and body weight (r =-0.092,-0.047,-0.033,P ＞ 0.05).The lengths between P2 and P4 planes,P1 and P4 planes were negatively correlated with the age (r =-0.343,-0.371,P ＜ 0.05),but positively correlated with the body weight (r =0.271,0.208,P ＜ 0.05).The length between P4 and P5 planes was positively correlated with the height and body weight (r =0.154,0.255,P ＜ 0.05).There were no significant difference in the lengths between P1 and P2 planes,P1 and P4 planes,P2 and P4 planes,P4 and P5 planes between males and females (t =-1.046,-1.274,-0.908,1.375,P ＞ O.05).The length between P2 and P4 planes was similar to the length of retrohepatic vena cava.The length between P2 and P4 planes(mm) =71.23-0.293 × age (years) +0.32 × body weight (kilogram).Conclusion The establishment of digital model of juxtahepatic vena cava based on the computed tomography imaging data is feasible,which provides basis for clinical investigation.

Objective To study the efficacy of surgical treatment in hilar cholangiocarcinoma patients. Methods One hundred and four cases underwent surgical treatment of hilar cholangiocarcinoma were retrospective enrolled in the study from 1998 to 2008, including 45 cases of radical resection, 38 cases of palliative resection, vitro bridge drainage in 21 cases, 93 cases of postoperative patients. Ninty-three patients were followed up for 5 - 67 months, the different procedures of the treatment was summerized. Results Oneyear survival rate of radical resection and palliative resection was 80. 0% ( 32/40 ) and 86. 8% ( 33/38 ),respectively. No significant difference between the two groups (P ＞0. 01 ) were found; 2-year survival rate was 67. 5% (27/40) and 39. 5% ( 15/38), with significant difference between the two groups (P ＜0. 01 ) ;3-year survival rates were 37.5% ( 15/40 ) and 13.2% ( 5/38 ), with significant difference between the two groups (P＜0. 05). Palliative resection had higher 1-year survival rate than in vitro bridge drainage(P ＜ 0.01).Conclusion Surgical treatment of hilar cholangiocarcinoma is the most effective way to prolong the survival time of radical resection, radical surgery had better efficacy than palliative surgery, and palliative surgery is superior to external drainage. In patients of severe jaundice combined with biliary drainage infection, preoperative bridge drainage would improve the safety.

Comparison study results by two thyroidectomy / 中国基层医药

Objective To compare the clinical efficacy between endoscopic thyroidectomy via breast approach conventional open thyroidectomy in patients with nodular goiter. Methods A series of 70 patients with unilateral nodular goiter divided into two groups, either receiving endoscopic thyroidectomy through breast approach(endoscopic group,35 cases),or conventional open thyroidectomy(open group,35 cases). The therapeutic efficacy was compared between the two groups. Results The operating time of endoscopic group was significantly longer in the endoscopic group (100.4±26.6)min than in the open group (73.5±14.5) min(t=5. 627, P=0. 000). The postoperative drainage volume in the endoscopic group (66.7±24.9) ml significantly more than that in the open group ( 13.3±6.4)ml( t = 14. 403, P = 0. 000 ). The postoperative hospital stasignificantly longer in the endoscopic group (4.3±1.1 )d than in the open group (3.6±0.9)d(t=2.886, P=0.005). And a satisfactory cosmetic result was achieved in significantly more patients in the endoscopic group(9/24 cases) than in the open group(34/51 )(x2 = 7.235, P=0.007). There was no significant difference in intraoperative loss between the endoscopic group (22.5±15.3)ml and the open group (18.3±7.5 )ml(t=1.273, P=0.207), a consumption of analgesics between the endoscopic group (9/24 eases) and the open group(21/51 cases) (X2=0.028, P=0.867), respectively. No severe complications was encountered ,such as massive hemorrhage,injuries of the recurrent or sularyngeal nerve, or parathyroidgland injury. Conclusion Both breast approach endoscopic thyroidectomy and conventional open thyroidectomy are safe and effective, former gives better cosmetic outcomes.
