Constraint-induced movement therapy (CIMT) has been a well-established rehabilitative method for upper limb paralysis in patients post-stroke. In recent years, its application to lower limb paralysis (Lower limb CIMT, L-CIMT) has been reported. However, the reported intensive lower limb trainings do not seem enough to target behavioral modifications in an individual's daily life. In this study, we investigated the effects of L-CIMT including the transfer package to induce behavioral transformation in normal daily life of patients with lower limb paralysis. The L-CIMT including the transfer package was administered to three patients with chronic-phase stroke without any constraint on the healthy lower limb for 3.5 hours a day, 5 days a week for 3 weeks. As a result, standing balance and walking ability were improved immediately and within 6 months after the intervention, respectively. All three cases experienced increased daily opportunities for standing and walking. We believe that L-CIMT including the transfer package can bring both short- and long-term improvements in standing balance and walking ability. This can lead to an increase in the frequency of standing and walking in daily living, along with an expanded range of action in ADL and IADL in patients with chronic-phase stroke.

We describe the use of a C1 laminar screw in combination with a C2 laminar screw as a salvage technique to treat two patients, one with persistent first intersegmental artery and the other with vertebral artery occlusion after cervical spine fracture. The combined use of C1 and C2 laminar screws allows for good fixation of the atlantoaxial joint with a lower risk of vertebral artery injury; therefore, it can be an alternative surgical procedure for patients with congenital or traumatic anomalous vertebral artery.

Introduction：There are few detailed evaluations of upper extremity function in Japan, especially for cervical spinal cord injury (CSCI). The capabilities of upper extremity test (CUE-T) evaluates upper extremity function, is specialized for CSCI, and is internationally used；however, there are few reports from Japan. This study verified the reliability, validity, and responsiveness of the CUE-T in Japan.Methods：We determined the interrater reliability, internal consistency, weighted kappa coefficient, intraclass correlation coefficient, and Cronbach's α coefficient for acute and chronic CSCI. The correlation coefficient with other evaluations was calculated and validated. Furthermore, the evaluation was performed twice at regular intervals, and the correlation between the change in CUE-T and other evaluations and the sensitivity to change using the standardized response mean (SRM) were verified.Results：The weighted kappa coefficient was 0.61-1.00, intraclass correlation coefficient was ≥0.9, and Cronbach's α coefficient were ≥0.9. The CUE-T and other evaluation methods showed moderate to strong correlations. In addition, the amount of change between CUE-T and the other evaluations were significantly correlated, and the SRM was ≥0.8.Discussion：In Japan, the CUE-T has been suggested to have good reliability, validity, responsiveness, and interpretability as an evaluation of upper extremity function in patients with CSCI. We will continue to verify the interpretability of the CUE-T and consider its dissemination in Japan.

In cancer gene therapy, restriction of antitumor transgene expression in a radiation field by use of ionizing radiation-inducible promoters is one of the promising approaches for tumor-specific gene delivery. Although tumor suppressor protein p53 is induced by low doses (<1 Gy) of radiation, there have been only a few reports indicating potential utilization of a p53-target gene promoter, such as that of the p21 gene. This is mainly because the transiently transfected promoter of p53-target genes is not much sensitive to radiation. We examined the response of the p21 gene promoter to low-dose radiation when transduced into a human breast cancer cell line MCF-7 by use of recombinant adeno-associated virus (rAAV) vectors. It was shown that the p21 gene promoter transduced by rAAV vectors was more highly radiation-responsive than that transiently transfected by electroporation. A significant induction of the p21 gene promoter by radiation of low doses down to 0.2 Gy was observed. When cells were transduced with the p21 gene promoter-driven HSVtk gene by rAAV vector, they were significantly sensitized to repetitive treatment with low dose radiation (1 Gy) in the presence of the prodrug ganciclovir. It was therefore considered that the p21 gene promoter in combination with a rAAV vector is potentially usable for the development of a low-dose radiation-inducible vector for cancer gene therapy.

Tonsillectomy is an operation generally carried out in otolaryngology. Postoperatively, the pain is very strong and it is often difficult to eat for several days. This time, we experienced a case after tonsillectomy in which rikkosan was effective for pain management. The patient was a 23-year-old woman. With a diagnosis of habitual tonsillitis, we performed her tonsillectomy. Postoperative pain was strong, however, it was difficult to use both non-steroidal anti-inflammatory drug and acetaminophen due to the history of drug eruption. Pain was alleviated immediately after taking rikkosan Subsequently we managed pain by using rikkosan as needed. Following a good postoperative course, she was discharged 6 days after surgery.

Crude drugs that feature the name “gui” have appeared in classical medicinal textbooks with different names,and the correspondence between their names and origins remains the subject of research and discussion. In the present study, we investigated these correspondences using the descriptions in the annotations of the Bencaojingjizhu and through our previous study that revealed the standards of weights and measures in this book. Based on this investigation, we strongly speculate that “gui” in the Bencaojingjizhu was the branch skin of Cinnamomum cassia (C. cassia) (corresponding to cinnamon sticks in the market), which fits with the descriptions about the length and weight of “gui” -related crude drugs in this book. We measured the contents of cinnamic aldehyde and coumarin in the branch skin of C. cassia, and compared these to contents in other crude drugs related to “gui” that can be obtained on the market. The contents of these two compounds in the branch skin of C. cassia were similar to those in the bark of C. cassia from Vietnam that meets the standards for cinnamon bark in the Japanese Pharmacopoeia and is regarded as high-grade in the market. These results support our speculation, and it might be possible that the branch skin of C. cassia can be used as medicine instead of cinnamon bark.
