Objective To guide the treatment of acute exacerbation of chronic obstructive puhnonary diseases (AECO- PD) through studing the principally related factors of AECOPD.Methods 190 AECOPD patients were investigated through retrospective study.First,we studied the thirty-two possible factors with single-factor analysis,then procee- ded to perform multiple-factor analysis with Logistic regression among the factors which P value was below 0.2 in single -factor analysis,and analyzed the principally related factors with two-factor correlation.Results According to Mul- tiple-factor analysis with Logistic regression analysis,there were eight factors that showed significance,which were us- age of respiratory excitant,LBC,usage of antioxidant,heart failure,Cr,selection of antibiotics respectively,WBC and Hb.Correlative analysis of the principally related factors showed no correlation between WBC and LBC.Conclusion The principally related factors of AECOPD prognosis were their recited in results.

The angle between the lower extremity force line and the position of the unicondylar prosthesis is an important factor affecting the long-term survival and rate clinical outcome of the unicondylar replacement prostheses. Insufficient lower limb alignment will accelerate the wear of prosthesis and reduce the survival rate of prosthesis. Excessive lower limb alignment will accelerate the progress of contralateral interventricular arthritis. It is generally believed that the lower limb force line should be corrected in mild varus after unicompartmental knee arthroplasty. However, some scholars believe that the lower limb alignment has no effect on the functional score and prosthesis survival rate after unicompartmental knee arthroplasty. The poor position of femoral and tibial prosthesis will cause unexplained pain and even prosthesis wear, but the optimal position of femoral and tibial prosthesis is controversial. It is generally believed that the posterior tibial slope should be corrected in the range of 3° to 7° in unicompartmental knee arthroplasty, but some scholars believe that excessive change of posterior tibial slope will also affect the balance of knee joint space and knee joint range of motion. This study shows that the correction of lower limb alignment to mild varus is still the best lower limb alignment for unicompartmental knee arthroplasty. The best position of femoral and tibial prosthesis needs to be confirmed by further biomechanical research. The correction of tposterior tibial slope should be changed according to the specific original dissection angle of patients before operation.

OBJECTIVE: To investigate the clinical effect the treatment of arthroscopy-assisted calcaneal spur resection combined with plantar fascia release and calcaneal decompression in the treatment of the patients with intractable calcaneal pain. METHODS: The clinical data of 50 patients with intractable heel pain from January 2016 to January 2019 were retrospectively analyzed, including 20 males and 30 females;aged from 40 to 68 years old with an average of (50.12±7.35)years old, the medical history ranged from 1 to 4 years. All patients underwent arthroscopy-assisted calcaneal spur resection combined with plantar fascia release and calcaneal decompression, and were followed up, the duration ranged from 24 to 60 months with an average of(42.00±3.28) months. All patients had obvious heel pain before surgery, and X-ray examinations often showed the presence of calcaneal spurs. In addition to the routine foot examination, the changes in the height and angle of the arch of the foot were also measured pre and post-operatively by X-ray, for the evaluation of clinical effect. The VAS system was used to evaluate the degree of foot pain;the AOFAS scoring system was used to comprehensively evaluate the foot pain, voluntary movement, gait and stability. RESULTS: The VAS decreased from (8.75±1.24) before surgery to (5.15±2.35) at 3 months after surgery, (4.07±2.53) at 6 months after surgery, and (3.95±2.44) at the last fllow-up(P<0.05). The AOFAS score increased from (53.46±4.17) before surgery to(92.46±2.53) at 3 months after surgery, (96.33±2.46) at 6 months after surgery, and (97.05±2.37) at the last follow-up(P<0.05). The arch height was (41.54±1.15) mm before operation and (41.49±1.09) mm after the operation, the difference was not statistically significant(P>0.05). The internal arch angle of the foot arch was (121±6)° before operation and (122±7)° after operation. The difference was not statistically significant(P>0.05). CONCLUSION Arthroscopy-assisted calcaneal bone spurs resection combined with plantar fascia release and calcaneal decompression exhibited great clinical effect for treating intractable heel.

OBJECTIVE: To explore the knowledge of, attitude to and practice in nutrition and food safety, the influence factors, and to provide reference for relevant health education programs. METHODS: A total of 510 randomly selected students from Grade 1 to 3 randomly selected were surveyed by a nutrition and food safety questionnaire in Huize of Yunnan Province and Zhen'an of Shaanxi Province. Multiple-linear regression was used to analyze the influence factors of nutrition and food safety. RESULTS: The correct answer rate on nutrition and food safety knowledge of the pupils from Grade 1 to 3 was 74.4%. Nutrition and food safety knowledge score was 11.16±2.51, but only 7.8% of the students correctly answered "How much water should we drink every day". Students who agreed that it is necessary to learn nutrition and food safety knowledge in school accounted for 78.6% and 73.9%, respectively. At least half of the students showed correct behaviors in 7 aspects. The students who ate beans and meat daily or regularly accounted for 28.4% and 34.9%, but only 9.2% of the students drank more than 7 cups of water daily. The multiple-linear regression showed that the major influence factors were the area, grade, status of lodge and singleton. CONCLUSION Education is needed for students to form better dietary habits, especially those in low grades, non-singleton, and in board schools.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.
