Objective To observe the incidence of radiation pneumonitis (RP) in patients with non-small cell lung cancer (NSCLC) or esophageal carcinoma treated by three-dimensional conformal radiation therapy (3DCRT), and investigate the predictive value of low dose volume of the lung on RP.Methods From Mar 2005 to Aug 2008, 161 patients with locally advanced NSCLC or esophageal carcinoma received 3DCRT. Fifty-three patients with NSCLC received radiotherapy of 60 Gy/30 -34 fx and concurrent chemotherapy of navelbine plus cisplatin (NP). Among the 108 patients with esophageal carcinoma with prescription doses ranging from 58 Gy/29 fx to 70 Gy/35 fx, 46 and 62 received 3DCRT alone or 3DCRT with concurrent chemotherapy of calcium folinate, 5-Fu and cisplatin (LFP), respectively. Univariate and multivariate analysis and receiver operating characteristics (ROC) curves were performed to assess the correlated factors of RP. Results The follow-up rate was 100%. The rate of RP was 57. 8% (93/161) for all patients, 94% (50/53,including 1 with Grade 4 and 1 with Grade 5) for patients with NSCLC, and 39.8% (43/108, none with Grade 4 and 5) for patients with esophageal carcinoma. The correlative factors included the sex, volume of gross tumor volume (GTV), mean lung dose (MLD), V5, V10, V15, V20, V25 and V30 of normal lung according to Spearman correlative analysis. Univariate analysis showed that all the 9 factors could predict RP. Only V5 and the volume of GTV were found independently associated with Grade 2 or more RP in multivariate analysis. ROC analysis indicated that the cut-off point of the curve was 55% with the area under ROC curve of 0. 684 (P = 0. 000). For the patients with lung V5 ≥ 55% and < 55% ,43% (36/84) and 18% (14/77) developed RP of Grade 2 or more, respectively. Conclusions Dosimetric parameters including MLD, normal tissue complication probability, and V5-V30 could predict RP. V5 may be the most valuable predictor. When V5 exceeds 55%, the probability of RP of grade 2 or more may increase notably. Besides the limitation of MLD, V20 and V30, the volume of low dose region should be also limited to a lower range during treatment planning.

Feline calicivirus (FCV) is an important and highly prevalent pathogen of cats that causes feline respiratory disease. The reverse genetic systems for FCV have been established in national and international laboratories since 1995. This technique has been used widely in FCV basic research and good progress has consequently been made to determine the relationship between viral genome structures and the function of their proteins, the expression of foreign proteins, virus-host interactions, and viral pathogenic mechanisms. In this article,we review the state of progress with regards to the establishment and application of the FCV reverse genetic operating system,which will provide a useful reference tool for future related research.

The enantiomers separation of thirteen drugs collected in Ch.P2010 was performed on chiral stationary phase of cellulose ramification (chiralpak OD and chiralpak OJ) by high performance liquid chromatographic (HPLC) methods,which included ibuprofen (Cl),ketoprofen (C2),nitrendipine (C3),nimodipine (C4),felodipine (C5),omeprazole (C6),praziquantel (C7),propranolol hydrochloride (C8),atenolol (C9),sulpiride (C10),clenbuterol hydrochloride (C11),verapamil hydrochloride (C12),and chlorphenamine maleate (C13).The mobile phase consisted of isopropanol and n-hexane.The detection wavelength was set at 254 nm and the flow rate was 0.7 mL/min.The enantiomers separation of these thirteen racemates on chiralpak OD column and chiralpak OJ column was studied,while the effects of proportion of organic additives,alcohol displacer and temperature on the separation were studied.And the mechanism of some of racemates was discussed.The results indicated that thirteen chiral drugs could be separated on chiral stationary phase of cellulose ramification in normal phase chromatographic system.The chromatographic retention and resolution of enantiomers could be adjusted by factors including column temperature and the concentration of alcohol displacer and organic alkaline modifier in mobile phase.It was shown that the resolution was improved with reducing concentration of alcohol displacer.When concentration of organic alkaline modifier was 0.2％ (v/v),the resolution and the peak shape were fairly good.Most racemates mentioned above had better resolution at column temperature of 25 ℃.When racemates were separated,the temperature should be kept so as to obtain stable separation results.

To assess the correlation between thyroid function and glucolipid metabolism in type 1 diabetic adults. A retrospective analysis was conducted in 230 type 1 diabetic adults who were hospitalized in the Department of Endocrinology of Shandong Provincial Hospital Affiliated to Shandong University from January 2008 to January 2020. It showed that thyroid stimulating hormone(TSH) was significantly positively correlated with total cholesterol (TC) ( r=0.239), triglycerides (TG) ( r=0.166) and low-density lipoprotein cholesterol (LDL-C) ( r=0.249), respectively (all P<0.05). Free triiodothyronine (FT 3) was significantly negatively correlated with fasting plasma glucose (FPG) ( r=-0.272), glycated hemoglobin (HbA1c) ( r=-0.240), TC ( r=-0.197) and LDL-C ( r=-0.220), respectively (all P<0.05). Free thyroxine (FT 4) was negatively correlated with TC ( r=-0.171) and LDL-C ( r=-0.170), respectively (all P<0.05). TC was an independent predictor of TSH, FT 3 and FT 4, FT 3 and FT 4 were independent predictors of HbA1c. TSH was an independent predictor of TC, TG and LDL-C. Thyroid function is closely related to glucolipid metabolism in type 1 diabetic adults.

Objective:To compare the postoperative tunnel enlargement and clinical outcomes of anterior cruciate ligament (ACL) reconstruction using the all-inside technique with the traditional outside-in graft introduction technique.Methods:A retrospective analysis was conducted on 47 patients with ACL injuries who were admitted to the First Hospital of the University of Science and Technology of China between December 2021 and July 2022. The patients were categorized into two groups based on the surgical approach used for ACL reconstruction. There were 25 cases in the all-inside group, 18 males and 7 females, aged 27.72±7.33 years, 17 cases on the left side and 8 cases on the right side; 22 cases in the traditional group, 11 males and 11 females, aged 27.82±7.12 years, 11 cases on the left side and 11 cases on the right side. Clinical parameters including the length of hospital stay, surgical duration, pain levels assessed via the visual analogue scale (VAS), Lysholm score, International Knee Documentation Committee (IKDC) score, and Tegner score were recorded and compared between the two groups. Additionally, femoral and tibial tunnel enlargement was evaluated using postoperative CT scans conducted one year after surgery.Results:All patients were followed up for 15.64±2.04 months (range, 12-21 months). The mean operation time was 178.60±42.90 min in the all-inside group and 133.60±28.77 min in the traditional group, indicating a statistically significant longer operation time in the all-inside group ( P<0.05). On postoperative days 1 and 15, the VAS scores were lower in the all-inside group (7.08±1.29 and 5.56±1.33 points) compared to the conventional group (7.96±1.29 and 6.32±1.13 points), with a statistically significant difference ( P<0.05). However, the differences in VAS scores between the two groups at postoperative months 1, 6, and 12 were not statistically significant ( P>0.05). The preoperative Lysholm, IKDC, and Tegner scores in the all-inside group and the conventional group were 34.00±18.63, 36.24±15.01, 1.20±1.12 points and 36.18±13.64, 38.23±14.94, 1.55±1.14 points, respectively, and at 6 months after surgery, respectively were 72.60±13.95, 74.12±12.03, 3.56±1.05 points, and 68.41±10.80, 66.59±17.93, 3.23±1.15 points, and at 12 months postoperatively were 92.32±5.23, 81.40±7.24, 5.28±1.62 points and 91.27±6.32, 82.18±7.26, 4.96±1.25 points. Both groups improved at 6 months postoperatively compared with preoperatively ( P<0.05), and further improved at 12 months postoperatively compared with 6 months postoperatively ( P<0.05), but the differences in each functional score between the two groups were not statistically significant at all time points ( P>0.05). At 1 year postoperatively, the values of femoral and tibial tunnel enlargement in the all-inside group (1.78±1.03 mm, 1.18±0.97 mm) were smaller than those in the conventional group (2.30±1.33 mm, 1.83±1.00 mm), and the differences were statistically significant ( P<0.05). The difference between the femoral side tunnel enlargement and tibial side enlargement in the traditional group was not statistically significant ( P>0.05), while the femoral side enlargement in the all-inside group was significantly larger than the tibial side ( P<0.05). The difference in Lysholm, IKDC and Tegner scores between grade 0 and grade 1 tunnel enlargement on the femoral side and tibial side was not statistically significant ( P>0.05). Conclusion:The short-term clinical outcomes following ACL reconstruction using the all-inside technique versus the traditional tunnel technique were comparable. However, early postoperative pain was less severe with the all-inside technique, and tunnel enlargement was smaller. The degree of bone tunnel enlargement did not significantly impact early clinical outcomes.

OBJECTIVETo investigate the hemodynamics evidence of the descending branch of lateral circumflex femoral artery in a reversed way. To explore the clinical result of using the reversed descending branch of the lateral circumflex femoral artery as the receipt artery for free flaps for reconstruction of the leg soft-tissue defect.

METHODSFrom October 2005 to February 2012, 38 patients with severe leg soft-tissue defects were treated. The proximal antegrade and retrograde mean artery pressure of the descending branch of the lateral circumflex femoral artery in 16 of 38 patients were recorded during operation. All wounds had osteomyelitis, bone and tendon exposure requiring coverage reconstruction. And there was no recipient artery in the injured lower leg for free flaps in all 38 patients. Reversed descending branches of lateral femoral circumflex arteries were used as recipient arteries for free flaps (free latissimus dorsi flap, free thoracoumbilical flap, and free anterolateral thigh flap) in all patients. The flap donor site was closed directly or with the skin graft.

RESULTSThe proximal antegrade mean artery pressure of the descending branch of lateral circumflex femoral artery was(81.6 +/- 12.4) mmHg. The proximal retrograde pressure was(48.2 +/- 10.7) mmHg. The proximal retrograde mean artery pressure was 59.07 percent of the proximal antegrade pressure. The donor skin graft survived and wound healed primarily. After operation, 2 flaps had distal partial necrosis and healing was achieved after dressing change. All the other flaps survived completely without vascular problems. All the patients were followed up for 11 months to 2.5 years (mean, 1.6 years). The flap appearance was satisfactory. The texture and color of flaps in all cases were good.

CONCLUSIONSThe reverse descending branch of lateral circumflex femoral artery is a reliable recipient artery for the free flaps. It is an easy and simple technique that can be used for reconstruction of the defects in the lower leg, with the reversed descending branch of lateral circumflex femoral artery as recipient artery.
