Objective:To evaluate the efficacy and toxicity of single-agent bendamustine in patients with indolent B-cell non-Hodgkin's lymphoma (NHL) refractory to rituximab. Methods:Between April 2010 and April 2013, 100 patients with rituximab-refrac-tory indolent B-cell NHL from 8 institutions were enrolled. Bendamustine was administered at 120 mg/m2 on days 1 and 2 every 21 days for 6-8 cycles. The primary endpoint was the overall response rate (ORR). The secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results:One hundred patients with a median age of 56 (rang-ing from 28 to 74) years were recruited in this clinical study. The total number of chemotherapy was 447 cycles, and the median number was 4 cycles. Ninety-three patients could be evaluated for efficacy. Fifteen patients (16.1%) had complete remission (CR), 52 (55.9%) had partial remission (PR), 22 (23.7%) had stable disease (SD), and 4 (4.3%) had progression disease (PD). The ORR and DCR were 72%and 95.7%, respectively. After a median follow-up of 26.6 months (ranging from 2 to 48.4 months), 59 patients (63.4%) had PD.The median PFS was 8.53 (95%CI:6.518-10.542) months, and PFS rate for 1 year was (40.6±5.3)%. Forty-eight patients (48%) had 3/4 grade adverse events, including leucopenia (26%), neutropenia (24%), and anemia (11%). Conclusion:Single-agent bendamustine produced a high rate of objective responses in patients with rituximab-refractory indolent B-cell NHL and could be one of the new op-tions for second-line treatment of these patients. The most common adverse event is hematologic toxicity.

Objective:To investigate the predictive values of baseline hematoma mean CT value and shape regularity (SR) for hematoma enlargement (HE) in patients with spontaneous intracerebral hemorrhage (ICH).Methods:Patients with ICH admitted to Yulin First Hospital from June 2018 to December 2021 were retrospectively included. The first head CT scan was performed within 24 h of onset, and the second head CT scan was performed within 72 h of the first scan. HE was defined as an increase in hematoma volume of at least 6 ml or 33% from the first CT. 3D Slicer software was used to reconstruct 3D images and SR was calculated. Multivariate logistic regression analysis was used to determine the independent factor for HE. Receiver operator characteristic (ROC) curve was used to evaluate the predictive value of baseline hematoma mean CT value for HE. Results:A total of 249 patients with ICH were enrolled, including 134 males (53.8%), and aged 62.2±12.1 years. The median baseline Glasgow Coma Scale score was 12, and the median time from onset to first CT scan was 3.1 h. The median baseline hematoma volume was 10.9 ml, and 58 patients (23.3%) showed HE. The baseline hematoma mean CT value in the HE group (58.5±3.2 HU vs. 60.3±3.3 HU; P<0.01) and baseline SR (0.615±0.146 vs. 0.688±0.100; P<0.001) were significantly lower in the non-HE group. Multivariate logistic regression analysis showed that the time from onset to first CT scan (odds ratio [ OR] 0.867, 95% confidence interval [ CI] 0.786-0.957; P=0.004), the baseline hematoma volume ( OR 1.050, 95% CI 1.028-1.073; P<0.001), and the baseline hematoma mean CT value ( OR 0.809, 95% CI 0.725-0.902; P<0.001) were the independent predictors of HE, while the baseline SR had no significant independent correlation with HE. ROC curve analysis showed that the area under the curve of baseline hematoma mean CT value for predicting HE was 0.652 (95% CI 0.573-0.731; P<0.001), with an optimal cutoff value of 57.97 HU. The sensitivity and specificity for predicting HE were 50% and 75.9%, respectively. Conclusion:The baseline hematoma mean CT value is an independent factor for HE in patients with ICH and has certain predictive value for HE.

Objective To explore the applicability of the three commonly used CT examination decision rules in Chinese head injured children. Methods This prospective observational study included 1538 children and adolescents (aged < 18 years), who were treated at the Emergency Department of First Hospital of Shanxi Medical University after head injuries. The three clinical decision rules include the Children's Head Injury Algorithm for the Prediction of Important Clinical Events (CHALICE; UK); the prediction rule for the identification of children at very low risk of clinically important traumatic brain injury, that was developed by the Pediatric Emergency Care Applied Research Network (PECARN; USA), and the Canadian Assessment of Tomography for Childhood Head Injury (CATCH) rule. Diagnostic accuracy had been evaluated by using the rule-specific predictor variables to predict each rule-specific outcome measure in populations who met inclusion and exclusion criteria for each rule. Sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and ROC curve were referred to the diagnostic accuracy. Indicators were characterized by 95% CI. Results Of the 1538 patients, CTs were obtained for 339 patients (22.04%). Forty-nine patients (3.19%) had positive CT results, 8 patients (0.52%) underwent neurosurgery, 2 patients (0.13%) died, and 1 patient (0.07%) may be missed. In this study, CHALICE was applied for 1394 children (90.70%; 95% CI: 89.24%-92.15%), PECARN for 801 children (52.11%; 95% CI: 49.62%-54.61%), and CATCH for 325 patients (21.15%; 95%CI: 19.10%-23.19%). The validation sensitivities of CHALICE, PECARN, and CATCH rules were 92.6%(74.2%-98.7%), 100% (56.1%-100%), and 85.7% (42.0%-99.2%), respectively; the specificities were 78.1%(75.7%-80.2%), 48.0% (44.5%-51.5%) and 70.8% (65.4%-75.6%); positive predictive value were 7.7% (5.1%-11.3%), 0.9% (0.4%-1.9%) and 6.1% (2.5%-13.2%); and negative predictive value were 99.8% (99.2%-100%), 99.1% (98.1%-99.6%), and 99.6% (97.2%-100%), respectively. Conclusions The clinical decision rules of CHALICE, PECARN and CATCH have high sensitivities. The specificity of PECARN rule is lower than those of CHALICE and CATCH rules. The above three clinical decision rules can be used for the decision of CT examination in Chinese children with head injury in practice.

OBJECTIVE:
To enhance the safety of nasal endoscopic surgery and decrease its complications of eyes.
METHOD:
Three patients of chronic rhinosinusitis and nasal polyposis with lipogranulomas of the eyelids after nasal endoscopic surgery and nasal packing of petrolatum gauze were reported and analyzed, and their treatment results were presented during the last 2 years.
RESULT:
The medial orbital wall injury occurred in all three patients during endoscopic sinus surgery. The patients developed an ipsilateral periocular swelling, eyelid hematoma and palpebral conjunctival edema during 2 to 3 hours after surgery. Nasal packs petrolatum gauze were removed 10-24 hours after surgery. The patients were discharged from hospital when periorbital swelling and eyelid ecchymoma disappeared, and nasal cavity obstruction was improved 6 to 8 days after surgery. The swelling and nodular mass of ipsilateral eyelids (one in left upper eyelid and two in right lower eyelid) were found 12-15 days after surgery, and their eye movement and eyesight were normal. Antibiotic and corticosteroid were administered for 3 4 weeks with only improvement in eyelid swelling. These masses of eyelids were completely excised through palpebral margin 1-6 months after surgery. The histopathological examination of the surgical specimens showed lipogranuloma. No recurrence and symptom of the eyes had been observed during 4-18 months follow up.
CONCLUSION
The lipogranuloma of the eyelid is a rare and late complication after nasal endoscopic surgery and nasal packing with vaspetrolatum gauze. The medial orbital wall injury and bleeding during surgery, and vaseline of nasal packing permeated into the eyelid are the direct causes of this complication. The application of petrolatum gauze should be avoided when the medial orbital wall trauma is identified. The complete excision of granulomas is a best effective therapy.
