Objective:To investigate and verify a novel acute graft versus host disease (aGVHD) prevention protocol in the context of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) .Methods:Patients who underwent haplo-HSCT in our center between January 2022 and December 2022 were included. All patients received reduced doses of cyclophosphamide, Rabbit anti-human tymoglobulin, ruxolitinib, methotrexate, cyclosporine, and MMF to prevent aGVHD. The transplantation outcomes, complications, and survival rate of all patients were investigated.Results:A total of 52 patients with haplo-HSCT were enrolled, 29 (55.8%) male and 23 (44.2%) female, with a median age of 28 (5-59) years. There were 25 cases of acute myeloid leukemia, 17 cases of acute lymphocyte leukemia, 6 cases of myelodysplastic syndrome, 2 cases of chronic myeloid leukemia and 2 cases of myeloproliferative neoplasms. 98.1% of patients had successful engraftment. The incidence of Ⅱ-Ⅳ aGVHD and Ⅲ-Ⅳ aGVHD was 19.2% (95% CI 8.2% -30.3% ) and 7.7% (95% CI 0.2% -15.2% ), respectively. No patients experienced severe gastrointestinal mucositis. The Epstein-Barr virus and CMV reactivation rates were 40.4% and 21.3%, respectively. 9.6% of patients relapsed during followup, with 1-year overall survival, progression-free survival, and non-relapse mortality rates of 86.5% (95% CI 76.9% -96.1% ), 78.8% (95% CI 67.4% -90.3% ) and 11.5% (95% CI 2.6% –20.5% ), respectively. Conclusion:Ruxolitinib combined with a low dose of PTCY is a safe and effective first-line aGVHD prevention strategy.

Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

OBJECTIVE: To explore the effectiveness of arthroscopic binding fixation using suture through single bone tunnel for posterior cruciate ligament (PCL) tibial insertion fractures in adults. METHODS: Between October 2019 and October 2021, 16 patients with PCL tibial insertion fractures were treated with arthroscopic binding fixation using suture through single bone tunnel. There were 11 males and 5 females with an average age of 41.1 years (range, 26-58 years). The fractures were caused by traffic accident in 12 cases and sports in 4 cases. The time from injury to operation ranged from 2 to 10 days with an average of 6.0 days. The fractures were classified as Meyers-McKeever type Ⅱ in 4 cases and type Ⅲ in 9 cases, and Zaricznyi type Ⅳ in 3 cases. There were 2 cases of grade Ⅰ, 7 cases of grade Ⅱ, and 7 cases of grade Ⅲ in the posterior drawer test. There were 3 cases combined with lateral collateral ligament injury and 2 cases with meniscus injury. The visual analogue scale (VAS) score, Lysholm score, International Knee Documentation Committee (IKDC) score, and knee range of motion were used to evaluate knee joint function. The posterior drawer test and knee stability tester (Kneelax 3) were used to evaluate knee joint stability. The X-ray films were used to evaluate fracture reduction and healing. RESULTS: All incisions healed by first intention after operation. There was no incision infection, popliteal neurovascular injury, or deep venous thrombosis of lower limbs. All patients were followed up 6-12 months, with an average of 10 months. X-ray films at 6 months after operation showed the fractures obtained bone union. There were 11 cases of grade 0, 4 cases of gradeⅠ, and 1 case of grade Ⅱin posterior drawer test, showing significant difference when compared with preoperative results ( Z=23.167, P<0.001). The VAS score, Lysholm score, IKDC score, knee range of motion, and the results of Kneelax3 examination all significantly improved when compared with preoperative results ( P<0.05). CONCLUSION For adult patients with PCL tibial insertion fractures, the arthroscopic binding fixation using suture through single bone tunnel has the advantages of minimal trauma, good fracture reduction, reliable fixation, and fewer complications. The patient's knee joint function recovers well.

In this study, we used a rat model of pulmonary arterial hypertension (PAH) induced by monocrotaline (MCT) to investigate the role and mechanism of angiotensin (Ang)-(1-7) in regulating pulmonary artery diastolic function. Three weeks after subcutaneous injection of MCT or normal saline, the right ventricular systolic pressure (RVSP) and right ventricular hypertrophy index (RVHI) of rats were detected using a right heart catheter. Vascular endothelium-dependent relaxation was evaluated by acetylcholine (ACh)-induced vasodilation. The relaxation function of vascular smooth muscle was evaluated by sodium nitroprusside (SNP)-induced vasodilation. Human pulmonary artery endothelial cells (HPAECs) were incubated with Ang-(1-7) to measure nitric oxide (NO) release levels. The results showed that compared with control rats, RVSP and RVHI were significantly increased in the MCT-PAH rats, and both ACh or SNP-induced vasodilation were worsened. Incubation of pulmonary artery of MCT-PAH rats with Ang-(1-7) (1 × 10^-9-1 × 10^-4 mol/L) caused significant vaso-relaxation. Pre-incubation of Ang-(1-7) in the pulmonary artery of MCT-PAH rats significantly improved ACh-induced endothelium-dependent relaxation, but had no significant effect on SNP-induced endothelium-independent relaxation. In addition, Ang-(1-7) treatment significantly increased NO levels in HPAECs. The Mas receptor antagonist A-779 inhibited the effects of Ang-(1-7) on endothelium-dependent relaxation and NO release from endothelial cells. The above results demonstrate that Ang-(1-7) promotes the release of NO from endothelial cells by activating Mas receptor, thereby improving the endothelium-dependent relaxation function of PAH pulmonary arteries.

One hundred eighty-four cases of awake craniotomy in Xijing Hospital from September 2010 to June 2019 were retrospectively included in the study.Patients were divided into Asleep-Awake-Asleep (AAA) group and monitored anesthesia care (MAC) group.In AAA group, general anesthesia was used in the early arousal period, sedatives and analgesics were stopped during the arousal period, and the bispectral index (BIS) value was maintained at 60-80 in the late arousal period.In MAC group, dexmedetomidine and remifentanil were intravenously infused in the early arousal period, and the BIS value was maintained at 60-80 in the late arousal pericd.Dexmedetomidine and remifentanil infused were reduced or stopped according to the Observer′s Assessment of Altertness/Sedation score during the arousal period, so that the patient could be awakened at any time, and the BIS value was maintained at 60-80 in the late arousal period.Compared with AAA group, the consumption of local anesthetic and remifentanil was significantly decreased, the operation and anesthesia time was shortened, the requirement for rescue analgesia was decreased, mean arterial pressure, end-tidal pressure of carbon dioxide (P ETCO 2) and partial pressure of arterial carbon dioxide (PaCO 2) were increased and partial pressure of arterial oxygen (PaO 2) was decreased after laryngeal mask insertion or sedation, and heart rate and PaO 2 were decreased, P ETCO 2 and PaCO 2 were increased after awakening in group MAC ( P<0.05). There were no significant differences in anesthesia failure rate in the awake craniotomy, incidence of adverse events during the arousal period, intraoperative incidence of tachycardia/bradycardia and hypertension/hypotension, Observer′s Assessment of Alertness/Sedation score during the arousal period, rate of postoperative visual analogue scale score>5 after surgery, postoperative requirement for rescue analgesia, neurological deficit rate and rehabilitation discharge rate between the two groups ( P>0.05). Compared with those after laryngeal mask insertion or after sedation, mean arterial pressure, heart rate, P ETCO 2 and PaCO 2 were significantly increased, and PaO 2 was decreased after awakening in AAA group ( P<0.05), and no statistically significant change was found in the parameters mentioned above after awakening in MAC group ( P>0.05). In summary, MAC shortens the operation and anesthesia time, no artificial airway is required, and it is suitable for the short time and minor operation.AAA has a better hemodynamics and oxygenation in the early arousal period, but the patient′s stress is more obvious after awakening, and effective prevention and intervention are needed.

Objective: To investigate the efficacy and safety of cuboid stereotactic aspiration of necrotic brain tissue for treating malignant middle cerebral artery infarction in the elderly patients. Methods: Sixteen elderly patients with malignant middle cerebral artery infarction were selected from June 2017 to January 2019 in our hospital. Patients were followed up for 6 months to evaluate the efficacy of stereotactic aspiration of necrotic brain tissue using the modified Rankin Scale (mRS). Results: The 30-day mortality was 18.75%. Among the 16 elderly patients, 6 (37.5%) had an mRS score of 3 (defined as moderate disability), 6 (37.5%) had an mRS score of 4 (defined as moderate to severe disability), 1 (6.25%) had an mRS score of 5 (defined as severe disability), and 3 (18.75%) had an mRS score of 6. The probability of 6-month favorable outcome, defined as an mRS score of ≤3, was 37.5%, and the 6-month mortality was 18.75%. Conclusions It is a simple, minimally invasive, effective and safe method to treat malignant middle cerebral artery infarction in the elderly patients with cuboid stereotactic aspiration of necrotic brain tissue, which needs to be confirmed by further randomized controlled studies.

ObjectiveTo evaluate the efficiency and safety of № I Empirical Prescription for Chronic Prostatitis (№ I EPCP) in the treatment of type Ⅲ refractory chronic prostatitis.

METHODSWe randomly assigned 53 cases of type Ⅲ refractory chronic prostatitis with damp-heat and blood stasis to an experimental and a control group to receive № I EPCP at 1 dose per day and saw palmetto extract at 160 mg bid), respectively, all for 8 weeks. Before and after 4 and 8 weeks of treatment, we obtained The National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) scores, Traditional Chinese Medicine Syndrome Scores (TCMSS), maximum urinary flow rate (Qmax), average urinary flow rate (Qavg), Hamilton Depression Rating Scale (HAMD) scores and Hamilton Anxiety Rating Scale (HAMA) scores, and compared them between the two groups of patients.

RESULTSTotally 48 of the patients completed the medication and follow-up, 25 in the experimental and 23 in the control group. Compared with the baseline, the NIH-CPSI scores after 8 weeks of treatment were significantly decreased in the experimental (27.82 ± 7.25 vs 15.46 ± 4.77, P <0.05) and the control group (25.98 ± 6.47 vs 21.06 ± 5.74, P <0.05), and so were the TCMSSs (24.64 ± 9.82 vs 16.42 ± 6.33 and 9.15 ± 3.74, P <0.05, and 23.67 ± 8.73 vs 18.55 ± 5.92 and 13.48 ± 4.45, P <0.05); the Qmax at 8 weeks were dramatically increased in the experimental group (［18.45 ± 7.81］ vs ［23.44 ± 8.73］ ml/s, P <0.05) and the control (［17.58 ± 6.92］ vs ［21.26 ± 8.32］ ml/s, P <0.05), and so was the Qavg (［11.27 ± 5.33］ vs ［16.51 ± 7.36］ ml/s, P <0.05 and ［10.66 ± 5.82］ vs ［13.44 ± 6.16］ ml/s, P <0.05); the HAMD scores were remarkably reduced in the experimental group (22.74 ± 6.37 vs 17.62 ± 5.71 and 12.54 ± 5.22, P <0.05) and the control (23.55 ± 7.14 vs 22.34 ± 6.88 and 21.62 ± 5.63, P <0.05), and so were the HAMA scores (21.37 ± 7.15 vs 18.42 ± 6.35 and 14.63 ± 7.11, P <0.05 and 20.54 ± 6.77 vs 19.87 ± 6.24 and 19.42 ± 7.04, P <0.05). No obvious adverse reactions were observed in either of the two groups during the medication.

CONCLUSIONS№ I EPCP deserves promotion and clinical application for its definite effectiveness and safety in the treatment of type Ⅲ refractory chronic prostatitis with damp-heat and blood stasis.

Objective: To investigate the efficiency and safety of hypofractionated radiotherapy (HFR) combined with chemotherapy using paclitaxel for the treatment of esophageal cancer (EC) patients with post-operative tracheoesophageal groove lymph node (TGLN) metastasis. Methods: A total of fifty-three post-operative EC patients with TGLN metastasis were randomly divided into HFR group (n=25), receiving a radiation of 60 Gy/20 fractions, and conventional fractionated radiotherapy (CFR) group (n=28), receiving a radiation of 60 Gy/30 fractions combined with chemotherapy using paclitaxel with a dosage of 50 mg once per week through tossing a coin. the adverse events and the prognosis between two groups were compared. Results: The incidence of radiation esophagitis and pneumonitis (grade 3-4) between the HFR group and CFR group showed no statistically significant difference (44.0%, 25.0%, P>0.05; 16.0%, 7.1%, P>0.05). No statistical difference was noticed in the efficiency between the HFR group and the CFR group (P>0.05). The efficiency in patients with lymph node metastasis at diameters ≤2 cm was significantly higher than that with lymph node metastasis at diameters >2 cm (P<0.05). The median overall survival (OS) of the HFR group showed a significant increase compared with that of the CRF group [24.2 months (95%CI 16.2-32.1 months) vs. 11.8 months (95%CI 9.2-14.4 months)] (χ²=5.063, P<0.05). Both univariate and multivariate analysis indicated that TGLN diameter (P<0.05) and fractioned types (P<0.05) were factors that affected the prognosis. Conclusions: The combination of HFR and chemotherapy contributed to the improvement of prognosis in EC patients with TGLN metastasis and there was no obvious increase in the adverse events.

Objective To compare the effect of clustered acupuncture of the scalp combined with constraint induced movement therapy (CIMT) with that of conventional acupuncture of the body points plus conventional rehabilitation intervention after cerebral infarction using blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI).Methods Thirty acute cerebral infarction patients with hemiplegia were equally divided into two groups at random.The test group received the clustered acupuncture of the scalp combined with CIMT,while the control group received the body point acupuncture plus conventional rehabilitation intervention.Before and after two weeks of treatment,blood oxygenation level-dependent functional magnetic resonance imaging at 3.0 T was performed during a passive digital opposition movement.The volume and intensity of the activated areas were compared.Fugl-Meyer assessment (FMA) was carried out as well.Results The most pronounced activation appeared in the contralateral somatosensory motor cortex for both groups.There was no significant difference in average FMA scores between the two groups before the treatment,but after the treatment the averages were significantly different.An increase in activated volume and intensity in the contralateral SMC was observed in both groups after the treatment,but the test group showed a much larger change in both activated volume and intensity.Conclusion The clustered acupuncture of the scalp combined with CIMT can achieve a more significant improvement in functional recovery after acute cerebral infarction than conventional acupuncture of the body points plus conventional rehabilitation intervention.Such combined therapy is worthy of application in clinical practice.

OBJECTIVETo investigate the effect of platelet-rich plasma (PRP) gel in total knee arthroplasty.

METHODSFrom January 2011 to January 2013, 30 patients of total knee arthroplasty were received PRP (PRP group) and 30 patients won't received PRP(normal saline group).Routine drainage and functional exercise were applied to the two groups after operation. Postoperative drainage volume, inflammatory reaction, grade of wound healed, Hospital for Special Surgery (HSS) Score for knee, the Feller Score for patella and range of motion (ROM) for knee were evaluated.Independent samples t-test, grade data used rank sum test were used to compared two groups.

RESULTSPostoperative drainage volume was (152 ± 22) ml in PRP group and (432 ± 35) ml in normal saline group. Postoperative drainage volume were statistically significant difference between two groups (t = 37.098, P < 0.05). At 4 days after operation, no inflammatory reaction was observed in 27 cases of PRP group and in 24 cases of normal saline group, mid inflammatory reaction in 2 cases of PRP group and in 4 cases of normal saline group, moderate inflammatory reaction in 1 cases of PRP group and in 2 cases of normal saline group.Wound healed by first intention in 30 patients of PRP group and in 29 patients of normal saline group (29/30), by second intention after 3 days of dressing change in 1 patient of normal saline group using 75% alcohol wet compressed. The adverse reaction rate was 3.3%. The average follow-up period was 16 months, ranging from 10 to 24 months. Three months postoperative HSS score for knee, scores of patellar, scores of anterior knee pain and ROM for knee were statistically significant difference in PRP group and normal saline group (t = 2.288, 2.097, 2.630, 2.104; all P < 0.05). Inflammatory reaction, grade of wound healed, final follow-up HSS score for knee, scores of patellar, scores of anterior knee pain and ROM for knee had no statistically significant difference between PRP group and normal saline group (P > 0.05).

CONCLUSIONSUsing PRP gel in total knee arthroplasty can reduce postoperative drainage volume, accelerate the healing of operation incision with no extra complications.It has good short-term clinical effect.
