ABSTRACT

Objective:To investigate the efficacy and adverse effects of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in preventing neutropenia in patients undergoing sequential adjuvant radiotherapy after postoperative chemotherapy for breast cancer.Methods:A total of 43 female patients with breast cancer from January 2017 to January 2019 in Shandong Cancer Hospital and Institute were analyzed prospectively. Twenty-one patients in the experimental group were given 6 mg of PEG-rhG-CSF subcutaneously 1-3 days before radiotherapy. In the control group, 22 patients were enrolled without PEG-rhG-CSF utilization. The lowest absolute neutrophil count (ANC), the number of days of radiotherapy interruption due to neutropenia, the number of recombinant human granulocyte colony-stimulating factor (rhG-CSF) used during radiotherapy and the occurrence of drug-induced skeletal muscle pain in the two groups were statistically analyzed.Results:No neutropenia fever was observed in the two groups during radiotherapy. In the experimental group, there was no case of grade Ⅲ neutropenia; while in the control group, there were 3 cases of grade Ⅲ neutropenia. The median value of the lowest ANC in the experimental group was 1.56×10 9/L, higher than that in the control group (1.37×10 9/L), with a statistically significant difference ( Z=-2.261, P=0.023). The median number of rhG-CSF used in the experimental group was 1, which was smaller than 2 in the control group, and the difference was statistically significant ( Z=-2.498, P=0.012). The median numbers of days of radiotherapy interruption due to neutropenia were 0 and 3 in the experimental group and the control group, with a statistically significant difference ( Z=-3.117, P=0.001). One case (4.8%) of drug-induced skeletal muscle pain was found in the experimental group and 5 cases (22.7%) in the control group, with no statistically significant difference ( χ2=1.586, P=0.208). Conclusion:PEG-rhG-CSF can effectively prevent neutropenia caused by radiotherapy after postoperative chemotherapy for patients with breast cancer, and can reduce the interruption of radiotherapy and the use of rhG-CSF during radiotherapy, which is helpful to the smooth process of radiotherapy.

ABSTRACT

Objective To explore the relationship between different types of female reproductive system dysplasia and age of visit, clinical manifestations, common types of combined malformations and endometriosis. Methods The patient′s medical records in the Second Hospital of Hebei Medical University from December 2002 to June 2016 were collected and retrospectively analyzed. Results Among 924 cases of genital tract dysplasia, uterine dysplasia (65.3%, 824/1 261) was the most common, followed by vaginal dysplasia (28.3%, 357/1 261), hymen atresia and urogenital fistula (3.7%, 47/1 261), and cervical dysplasia (2.6%, 33/1 261). (1) The youngest age was in patients with hymen atresia and urogenital fistula, with a median of 14.5 years old, while the older age were in patients with uterine, vaginal and cervical dysplasia, with median age of 25.0, 24.0 and 23.0 years old, respectively. (2) The clinical manifestations were lack of specificity, mainly abnormal findings of physical examination or accessory examination, primary amenorrhea, lower abdominal pain, infertility, adverse pregnancy history. (3) About other systemic malformations, urological malformations were the most common (4.8%, 44/924), followed by spinal malformations (0.5%, 5/924), inguinal hernia (0.4%, 4/924), heart malformations (0.2%, 2/924), cleft lip and palate (0.2%, 2/924). Oblique vaginal septal syndrome and MRKH syndrome were the most likely to be associated with other system malformations. (4) About combination with endometriosis, there was no significant difference between obstructive genital tract malformations (2.3%, 9/385) and non obstructive genital tract malformations (1.7%, 9/539; P=0.469). Conclusions Female reproductive system dysplasia is the most common in uterine dysplasia, followed by vaginal dysplasia, hymen atresia and urogenital fistula, and cervical dysplasia. The age of visit is generally older, often found by abnormal findings of physical examination or accessory examination, primary amenorrhea, lower abdominal pain, infertility, adverse pregnancy history;and could be combined with a variety of other system malformations, most seen by urinary system malformations,there is also the risk of endometriosis.

ABSTRACT

Objective To investigate the efficacy of ventilation with selective lobar collapse for thoracic surgery in elderly patients with chronic obstructive pulmonary disease (COPD).Methods Thirty ASA Ⅱ or Ⅲ patients with COPD,aged 65-80 yr,with a body mass index of 16-28 kg/m2,undergoing radical resection of esophagus cancer,were randomly divided into 2 groups (n=15 each):one-lung ventilation (OLV) group and ventilation with selective lobar collapse group (group SLC).In group OLV,OLV was performed,while in group SLC,the balloon of the blocker was placed at 0.5 cm below the opening of the upper lobe bronchus and the lower lobe was collapsed when chest was open.The patients were mechanically ventilated (VT =7-8 ml/kg,RR =14-16 bpm,I∶E=1∶1.5-2.0,FiO2 =100%).Peak pressure (Ppeak),plateau pressure (Pplat),airway resistance (Raw),and dynamic lung compliance (Cd) were measured at 10 min of two-lung ventilation in supine position (T0),at 5,45 and 90 min of OLV or selective lobar collapse (T1-3) and at 10 min of two-lung ventilation in lateral position after the end of operation (T4).Arterial blood samples were obtained at To,T3 and T4 for blood gas analysis.Oxygenation index (OI),alveolar-arterial oxygen gradiant (P(A-a)O2),and respiratory index (RI) were calculated.Results Ppeak,Pplat and Raw were significantly lower at T2-4,while Cd was significantly greater at T1-4,OI was significantly higher at T3,4,and P(A-a)O2 and RI were significantly lower at T3,4 in group SLC than in group OLV.Conclusion The thoracic operation can be completed safely using ventilation with selective lobar collapse and OLV,however,ventilation with selective lobar collapse can improve oxygenation and provides better ventilatory efficacy than OLV in elderly patients with COPD.
